Taking the physical row number as 240 row, the refresh row number of the display signal is 120 rows at this time, which improves the refresh rate.

The filling layer 44 is located on the side of the driving back plate 41 facing the light emitting diodes 42 and is filled between the adjacent light emitting diodes 42.

That is, each LED can control the light emission of 5-100 pixels. In the case that R, G, B are bound (bonding) together to form an LED light-emitting group, the ratio of the number of the LED light-emitting groups to the number of the pixels can be 1: 5-1: 100. That is, each LED light emitting group can control the light emission of 5-100 pixels.

The embodiment of the present disclosure further provides a method for displaying an image, which is applied to a graph source processing module, and the method includes:

s210, determining the resolution of the image data of the sub-frame of the image to be displayed according to a display device, wherein the display resolution of the display device is smaller than the display resolution corresponding to the processable data of the image source processing module;

s220, reconstructing the image data of each subframe picture of the image to be displayed according to the resolution of the image data of the subframe picture and the resolution of the processable data of the image source processing module to obtain reconstructed image data corresponding to each subframe picture, wherein the row resolution of the reconstructed image data is the same as that of the processable data of the image source processing module;

s230, performing data fusion on the reconstructed image data corresponding to each subframe picture of the images to be displayed in the preset number according to the data processable resolution of the image source processing module to obtain a synthetic image corresponding to the fused image data, wherein the resolution of the synthetic image is the same as the display resolution corresponding to the data processable by the image source processing module;

and S240, transmitting the image data of the synthesized picture from the picture source processing module to the display device so as to display the image to be displayed through the display device.

For example, the display device in the embodiment of the present disclosure may be adopted as the display device, and the display device includes a plurality of pixels, but each pixel does not distinguish a sub-pixel. The data voltage is used for realizing gray scale, and the color of the display device is realized through the LED lamps with different colors in the light source module. The image source processing module may include a plurality of pixels, and each pixel may include a plurality of sub-pixels, for example, three sub-pixels, which are an R sub-pixel, a G sub-pixel, and a B sub-pixel, respectively.

It should be noted that the resolution of an image or picture is p × q, which means that the resolution of a line is p, and each line has p pixels; the column resolution is q, with q pixels per column. The resolution of the data is p × q, which means that the resolution of the line is p, and each line has p data; the column resolution is q, with q data per column.

Illustratively, an image to be displayed, such as a color image, usually includes three sub-frames, such as an R sub-frame, a G sub-frame, and a B sub-frame, as shown in fig. 9, and fig. 9 is a sub-frame decomposition diagram of the image to be displayed. The resolution of the sub-frame is the same as the resolution of the image to be displayed. When the display device adopts one-row data scanning and one-column data transmission, the resolution of the image data is the same as the display resolution of the display device when the display device displays a subframe picture. The resolution of the image data may also be referred to as a signal input resolution.

For example, the resolution of the image to be displayed is 240 × 360, and then the resolution of each sub-frame is 240 × 360. In the case where the display device employs one-line data scanning and one-column data transmission, the resolution of the image data of the sub-frame is 240 × 360, that is, in the image data of the sub-frame, 360 data are provided per line and 240 data are provided per column. When the display device in the embodiment of the present disclosure is used, two data lines in the display device transmit data at the same time, and two gate lines transmit the on signal at the same time, so that the resolution of the image data of the sub-frame is 120 × 720.

It should be noted that the graph source processing module is used to process data, and the graph source processing module may be an independent module or a data processing module in a display device. The display resolution corresponding to the processable data of the image source processing module is the resolution of an image displayed by the display panel when the image source processing module is connected with the display panel.

For example, to increase the image refresh rate, the display resolution of the display device is smaller than the display resolution corresponding to the processable data of the image source processing module, that is, the row resolution of the display device is smaller than the row resolution of the display resolution corresponding to the processable data of the image source processing module, and the column resolution of the display device is smaller than the column resolution of the display resolution corresponding to the processable data of the image source processing module. It is understood that the display resolution of the display device is the resolution of an image that can be displayed by the display device, and in the case that the image source processing module is another display device, the display resolution of the image source processing module is the resolution of an image that can be displayed by the image source processing module. For an image or picture, the row resolution is the number of pixels per row and the column resolution is the number of pixels per column.

In the related art, the color separation can be reduced by increasing the refresh rate, reducing the color saturation of the light source, and reducing the brightness, but the reduction of the color saturation leads to poor display effect, and the reduction of the brightness does not show good picture effect.

The method for displaying an image according to the embodiment of the present disclosure reconstructs image data of each sub-frame of an image to be displayed, performs data fusion on the reconstructed image data corresponding to each sub-frame of a preset number of images to be displayed according to the resolution of processable data of the image source processing module, to obtain a composite image corresponding to the fused image data, where the resolution of the composite image is the same as the display resolution corresponding to the processable data of the image source processing module, so that the image data of the composite image can be transmitted from the image source processing module to a display device, and the image to be displayed is displayed by the display device. Because the display resolution of the display device is smaller than the display resolution corresponding to the processable data of the image source processing module, and the image data of the synthesized image corresponds to the image data of the preset number of images to be displayed, when the image data of the synthesized image is transmitted to the display device to be displayed, and the image data of one frame of the synthesized image is refreshed by the image source processing module, the display device can refresh the preset number of images to be displayed, so that the refresh rate of the display device is improved, and the effect of inhibiting color separation is achieved.

In one embodiment, step S230 may include: sequentially arranging the reconstructed image data corresponding to each subframe picture of a preset number of images to be displayed to obtain the arranged image data corresponding to the preset number of images to be displayed, wherein the row resolution of the arranged image data is the same as that of the reconstructed image data corresponding to each subframe picture; and performing data synthesis on the arranged image data according to the resolution of the processable data of the image source processing module to obtain a synthetic image, wherein the resolution of the synthetic image is the same as the display resolution corresponding to the processable data of the image source processing module.

For example, the reconstructed image data corresponding to each sub-frame of the preset number of images to be displayed may be sequentially arranged according to the principle of field sequential display, so that sub-frames of different colors may be displayed in a time-sharing manner. For example, a first color sub-frame, a second color sub-frame, and a third color sub-frame are sequentially displayed so that a preset number of images to be displayed can be displayed.

In an embodiment, reconstructing the image data of each sub-frame of the image to be displayed according to the resolution of the image data of the sub-frame and the resolution of the processable data of the image source processing module, to obtain the reconstructed image data corresponding to each sub-frame, may include: reconstructing each i row of data in the image data of each sub-frame picture into a row of data, wherein each sub-frame picture comprises j rows of data, and j is an integral multiple of i; and acquiring reconstructed image data corresponding to each subframe picture, wherein the line resolution of the reconstructed image data is the same as the line resolution of the processable data of the image source processing module, and the line number of the reconstructed image data is j divided by i.

Illustratively, the processable data of the map source processing module corresponds to a display resolution of 1920 × 1080. Taking the R sub-frame picture as an example, the resolution (i.e., display resolution) of the R sub-frame picture is 240 × 360. With the display device in the embodiment of the present disclosure, the resolution of the image data of the R sub-frame is 120 × 720, as shown in fig. 10, fig. 10 is a schematic diagram of the resolution of the image data of the R sub-frame in an embodiment of the present disclosure.

And reconstructing each 8 rows of data in the image data of the sub-frame into one row of data according to the resolution of the image data of the sub-frame. For example, i is set to 8, the image data of the R sub-frame picture is 120 lines of data from top to bottom, i.e., j is 120, the data amount of each line is 720, 1 to 8 lines, 9 to 16 lines, …, and 113 to 120 lines of the 120 lines of data are respectively reconstructed into one line of data, the resolution of the reconstructed image data is 15 × 5760, i.e., the reconstructed image data is 15 lines of data, each line has 5760 data, as shown in fig. 11, which is a schematic diagram of the reconstructed image data in an embodiment of the present disclosure in fig. 11. The line resolution of the reconstructed image data is 5760, the line resolution of the display resolution of the map source processing module is 1920, and k is 3(k is the number of channels of the map source processing module, that is, the number of channels of the map source processing module for transmitting data). It should be noted that the number k of channels of the map source processing module is not limited to 3, and may be other values. The line resolution of the display resolution corresponding to the processable data of the image source processing module is the line resolution of the processable data of the image source processing module divided by the number k of channels.

It can be understood that the specific value of i needs to be determined according to the line resolution of the image data of the sub-frame and the line resolution of the processable data of the image source processing module, so that the line resolution of the reconstructed image data corresponding to the sub-frame is the same as the line resolution of the processable data of the image source processing module, that is, the line resolution of the reconstructed image data corresponding to the sub-frame is k times the line resolution of the display resolution of the image source processing module.

In an embodiment, the image to be displayed includes a first sub-frame, a second sub-frame and a third sub-frame, and the sequentially arranging the reconstructed image data corresponding to each sub-frame of the preset number of images to be displayed to obtain the arranged image data corresponding to the preset number of images to be displayed may include: sequentially arranging the reconstructed image data corresponding to each subframe picture of the image to be displayed to obtain the reconstructed image data corresponding to the image to be displayed, wherein the row resolution of the reconstructed image data corresponding to the image to be displayed is the same as that of the reconstructed image data corresponding to each subframe picture, and in the reconstructed image data corresponding to the image to be displayed, the number of times of repetition of the reconstructed image data corresponding to each subframe picture is m, and m is a positive integer which is not 0; and sequentially arranging the reconstructed image data corresponding to the preset number of images to be displayed to obtain the arranged image data corresponding to the preset number of images to be displayed, wherein the row resolution of the arranged image data is the same as that of the reconstructed image data corresponding to the images to be displayed.

Illustratively, the reconstructed image data corresponding to the image to be displayed needs to be obtained first, and since the image to be displayed includes the first sub-frame picture, the second sub-frame picture and the third sub-frame picture, the reconstructed image data corresponding to each sub-frame picture of the image to be displayed is arranged in sequence, so that the reconstructed image data corresponding to the image to be displayed can be obtained. For example, the reconstructed image data of the image to be displayed includes reconstructed image data corresponding to a first subframe picture, reconstructed image data corresponding to a second subframe picture, and reconstructed image data corresponding to a third subframe picture, which are sequentially arranged. The arrangement rule of the reconstructed image data corresponding to each sub-frame is to keep the line resolution unchanged, so that the line resolution of the reconstructed image data corresponding to the image to be displayed is the same as the line resolution of the reconstructed image data corresponding to each sub-frame.

The reconstructed image data corresponding to the preset number of images to be displayed are sequentially arranged, and the arranged image data corresponding to the preset number of images to be displayed can be obtained. The arrangement rule of the reconstructed image data corresponding to the preset number of images to be displayed is to keep the line resolution unchanged, so that the line resolution of the arranged image data is the same as that of the reconstructed image data corresponding to the images to be displayed, and the line resolution of the reconstructed image data corresponding to each subframe picture is the same.

For example, if the predetermined number is 16, the number of the first sub-frame, the second sub-frame and the third sub-frame is 16. The first sub-frame may be an R sub-frame, the second sub-frame may be a G sub-frame, and the third sub-frame may be a B sub-frame. Fig. 12 is a schematic diagram of image data after arrangement in an embodiment of the present disclosure, and as shown in fig. 12, m is 1, that is, in the reconstructed image data corresponding to the image to be displayed, the number of times of repetition of the reconstructed image data corresponding to the R subframe picture, the reconstructed image data corresponding to the G subframe picture, and the reconstructed image data corresponding to the B subframe picture is all 1. Arranging the reconstructed image data corresponding to the R subframe picture, the reconstructed image data corresponding to the G subframe picture and the reconstructed image data corresponding to the B subframe picture in sequence to obtain the reconstructed image data corresponding to the image to be displayed, wherein the reconstructed image data corresponding to the image to be displayed is 15 × 3-45 lines; and sequentially arranging the reconstructed image data corresponding to the 16 groups of images to be displayed to obtain the arranged image data, wherein the arranged image data is 45-16 lines. Therefore, the arranged image data shown in fig. 12 is 15 × 3 × 16 — 720 lines, and 5760 pieces of data are provided for each line. The arrangement mode accords with the principle of field sequential display and is convenient for displaying the sub-frame pictures with different colors in a time-sharing manner.

In one embodiment, the data synthesizing the arranged image data according to the resolution of the processable data of the image source processing module to obtain the composite picture may include: respectively storing the arranged image data in k channels of the image source processing module; and supplementing a plurality of lines of virtual data into the k channels to obtain synthetic pictures corresponding to the preset number of images to be displayed, wherein the resolution of the synthetic pictures is the same as the display resolution corresponding to the data processable by the image source processing module.

Illustratively, each pixel of the map source processing module includes R, G, and B sub-pixels, and therefore, the number of channels of the map source processing module is 3, i.e., k is 3, that is, the map source processing module has 3 channels for transmitting data. Each line of the arranged image data has 5760 data, 5760 data are stored in 3 channels respectively, each channel can store 5760/3-1920 data, as shown in fig. 13, and fig. 13 is a schematic diagram of a synthesized picture in an embodiment of the present disclosure. The number of lines of the image data remains unchanged, and therefore, the number of lines remains 720 lines.

The processable data of the source processing module corresponds to a display resolution of 1920 x 1080, and multiple lines of virtual (dummy) data may be supplemented in order to match the data format of the composite picture with the data format of the source processing module. Fig. 13 may be supplemented with 360 rows of dummy data, as shown in fig. 13, so as to obtain a composite picture corresponding to the image to be displayed, where the composite picture is a Full High Definition (FHD) picture, and the resolution of the composite picture is 1920 × 1080, which is the same as the display resolution corresponding to the processable data of the image source processing module.

In one embodiment, the data synthesizing the arranged image data according to the resolution of the processable data of the image source processing module to obtain the composite picture may include: supplementing multiple lines of virtual data into the arranged image data so that the line number of the supplemented image data is the same as the column resolution of the data processable by the image source processing module; and respectively storing the supplemented image data in k channels of the image source processing module to obtain synthetic images corresponding to the preset number of images to be displayed, wherein the resolution of the synthetic images is the same as the display resolution corresponding to the processable data of the image source processing module.

Illustratively, the number of rows of the arranged image data is 720, and the processable data of the map source processing module corresponds to a resolution of 1920 × 1080. In order to make the number of rows of data the same as the column resolution of the image source processing module, multiple rows of virtual data may be supplemented to the arranged image data. In fig. 13, 360 rows of dummy data may be padded, so that the number of rows of padded image data is 1080, which is the same as the column resolution of the display resolution corresponding to the processable data of the image source processing module. The supplemented image data has 5760 data per line, and the 5760 data are stored in 3 channels respectively, and each channel can store 5760/3-1920 data, as shown in fig. 13. Each column of the supplemented image data has 1080 data, so that a composite picture can be obtained, the resolution of the composite picture is 1920 × 1080, the display resolution corresponding to the processable data of the image source processing module is the same, and the data format of the composite picture is the same as that of the image source processing module.

In one embodiment, transmitting the image data of the synthesized picture from the picture source processing module to the display device to display the image to be displayed through the display device may include: and transmitting the image data of the synthesized picture from the image source processing module to the display device in a signal buffering and distributing mode so as to display the image to be displayed through the display device. Illustratively, the image source processing module may be coupled to a display panel through which the composite picture is displayed. The data scanning is line scanning, and each 15 lines of data corresponds to one sub-frame picture in the image source processing module, so that the display device can display one sub-frame picture every 15 lines of data are scanned by the image source processing module. After the image source processing module scans a frame of data (i.e. 1080 lines of data), the display panel connected to the image source processing module can display a frame of image, and the display device can display 48 subframes of image. It can be understood that when the image source processing module scans dummy data, the display device has no corresponding sub-frame display. The refresh frequency of the map source processing module is 60Hz, and then, for the sub-frame picture, the refresh frequency of the display device is 48 × 60 — 2880Hz, so that the high refresh rate of the display device is realized, and the color separation can be effectively suppressed. It should be noted that the image to be displayed includes 3 sub-frame pictures, and the refresh frequency of the image source processing module is 60Hz, so that the refresh frequency of the display device is 16 × 60 — 960Hz for the image to be displayed.

It should be noted that the image to be displayed may be a still image, and the reconstructed image data corresponding to the 16 groups of images to be displayed are the same. The refresh frequency of the map source processing block is 60Hz, and then, for the image to be displayed, the display apparatus refreshes 960 times the image to be displayed (the same sub-image) within 1 second.

It can be understood that after the image source processing module scans a frame of data, a frame of picture displayed by the display panel connected to the image source processing module is a messy code, and the corresponding data can display an image to be displayed through the display device.

It should be noted that the specific numerical values of the preset number may be set as needed, and when the preset number is different, the number of rows of the dummy data added in the data synthesis process is different.

In one embodiment, in the reconstructed image data corresponding to the image to be displayed, the number of times of repetition of the reconstructed image data corresponding to each subframe picture may be set, so that the display device obtains different refresh frequencies. That is, the map source processing module may repeat the multi-subframe refresh same signal so that the display device may obtain different display frequencies.

Fig. 14 is a schematic diagram of image data after arrangement according to another embodiment of the present disclosure. As shown in fig. 14, m is 2, that is, in the reconstructed image data corresponding to the image to be displayed, the number of times of repetition of the reconstructed image data corresponding to each sub-frame is 2, that is, 2 sub-frames are repeated. Then, in the image source processing module, every 30 lines of data corresponds to one sub-frame, so that the display device can display one sub-frame every 30 lines of data scanned by the image source processing module. After the image source processing module scans a frame of data (i.e. 1080 rows of data), the display device can display 24 sub-frame pictures, so that the display device can realize a refresh rate of 1440Hz when the image source processing module has a refresh rate of 60 Hz. Similarly, if m is 4, that is, 4 subframes are repeated, the display device can realize a refresh rate of 720 Hz; m is 8, namely 8 subframes are repeated, and the display device can realize a refresh rate of 360 Hz; with 16, i.e. 16 subframes repeated, the display device can achieve a refresh rate of 180 Hz.

According to the method for displaying the image, the display device can achieve 5-level refresh rate adjustment by controlling the number of the repeated subframes of the image source processing module.

Fig. 15 is a block diagram of an apparatus for displaying an image according to an embodiment of the present disclosure. The embodiment of the disclosure also provides a device for displaying images, which is applied to the image source processing module. As shown in fig. 15, the apparatus for displaying an image includes:

and a data transmission module 54 for transmitting the image data of the synthesized picture from the picture source processing module to the display device to display the image to be displayed through the display device.

The embodiment of the present disclosure further provides a driving method of a light source module, which is applied to a display device, where the display device includes the light source module, the light source module includes a driving backplane and a plurality of light emitting diodes arranged on one side of the driving backplane, the plurality of light emitting diodes include a plurality of first color light emitting diodes, a plurality of second color light emitting diodes, and a plurality of third color light emitting diodes, and the method includes:

s310, dividing an image to be displayed into a plurality of sub-areas, and determining an area color gamut triangle corresponding to each sub-area, wherein the area color gamut triangle is positioned inside the color gamut triangle of the image to be displayed, the light source module is divided into a plurality of unit areas, and the plurality of sub-areas correspond to the plurality of unit areas one to one;

and S320, under the condition of displaying one sub-frame picture, controlling the first color light-emitting diode, the second color light-emitting diode and the third color light-emitting diode in each corresponding unit area to be lightened according to each area color gamut triangle, so that each unit area displays the color of the corresponding vertex in the corresponding area color gamut triangle, wherein the corresponding vertex is the vertex corresponding to the color of the sub-frame picture in the vertex of the area color gamut triangle.

For example, the light source module may be divided into a plurality of unit regions, and each unit region includes at least one first color light emitting diode, at least one second color light emitting diode, and at least one third color light emitting diode. Each unit area of the light source module can be preset, and can also be divided in the driving process.

For example, the image to be displayed is divided into a plurality of sub-regions, the image to be displayed may be divided into a plurality of sub-regions according to the resolution of the image to be displayed, and each sub-region may include the same number of pixels.

It should be noted that the resolution of the image to be displayed is the same as the resolution of the display device, and each sub-area in the image to be displayed corresponds to each unit area in the light source module one to one. For example, the image to be displayed is divided into 4 × 4 — 16 sub-regions, and correspondingly, the light source module is divided into 4 × 4 — 16 unit regions.

Illustratively, the image to be displayed may include a first color sub-frame, a second color sub-frame, and a third color sub-frame. For example, the first color may be R, the second color may be G, and the third color may be B. It is understood that the image to be displayed may include more colored sub-frames, and correspondingly, the leds include more colored leds, and the colors are not limited to R, G, B.

Fig. 16 is a schematic diagram of a color gamut range of an image to be displayed in an embodiment of the disclosure.

It can be understood that there is an original color gamut range in the image to be displayed, there is a corresponding color gamut triangle 50 in the image to be displayed, and color points of pixels in the image to be displayed are all located in the color gamut triangle 50. The color gamut triangle 50 of the image to be displayed is a 100% saturation color gamut relative to the area color gamut triangle corresponding to each subregion of the image to be displayed.

The area gamut triangles 51 corresponding to the respective sub-areas are all located inside the gamut triangle 50 of the image to be displayed, and therefore, each area gamut triangle 51 is a low saturation gamut. When the light emitting diodes in the corresponding unit area are driven to light up by using each area color gamut triangle 51, the light emitting diodes of the three colors in the corresponding unit area are simultaneously lighted up.

As shown in fig. 16, the respective area gamut triangles 51a, 51b, 51c and 51d corresponding to the determined four sub-areas are shown in fig. 16. Illustratively, in the case of displaying the R sub-frame picture, the R, G, and B light-emitting diodes in the unit areas corresponding to the four sub-areas, respectively, are controlled to be turned on according to the area color gamut triangles 51a, 51B, 51c, and 51d, so that the unit area corresponding to the area color gamut triangle 51a displays the color of the right vertex of the area color gamut triangle 51a, for example, all of the R, G, and B light-emitting diodes in the unit area corresponding to the area color gamut triangle 51a are turned on to display the color of the right vertex of the area color gamut triangle 51 a; similarly, the unit region corresponding to the region color gamut triangle 51b displays the color of the right vertex of the region color gamut triangle 51 b; the unit region corresponding to the region color gamut triangle 51c displays the color of the right vertex of the region color gamut triangle 51 c; the unit region corresponding to the region gamut triangle 51d displays the color of the right vertex of the region gamut triangle 51 d. In fig. 16, the right vertex of the color gamut triangle 50 is R, the upper vertex is G, and the left vertex is B. Thus, the colors displayed by each unit area are all low saturation color gamut.

In the related art, when the original color gamut range of the image to be displayed is used for displaying, good image quality can be displayed. For example, when displaying an R sub-frame picture, only the R leds are on, while the G, B leds are not. However, when the field sequential display is adopted, the color separation effect is severe due to the color separation effect. In the related research, it is proposed that color separation can be reduced by reducing the color saturation of the light source, and when a low-saturation color gamut is adopted, the color gamut triangle is reduced, and the reduced color gamut triangle is adopted to drive display, so that although the color separation effect is remarkably relieved, the overall image quality is also affected, and the display effect is poor.

The driving method of the light source module divides an image to be displayed into a plurality of sub-areas, the light source module is divided into a plurality of unit areas, the plurality of sub-areas correspond to the plurality of unit areas one by one, and area color gamut triangles corresponding to the sub-areas are determined, and all the area color gamut triangles are low-saturation color gamuts; and controlling the first color light-emitting diode, the second color light-emitting diode and the third color light-emitting diode in each corresponding unit area to be lightened according to each area color gamut triangle so that the unit area displays the color of the corresponding vertex in the corresponding area color gamut triangle. In such a mode, the light source module is partitioned, and the unit areas corresponding to the area color gamut triangle control of the low-saturation color gamut are used for displaying, so that each unit area is driven by the low-saturation color gamut, and the color separation effect can be effectively reduced. In addition, the area color gamut triangles corresponding to all the unit areas can be spliced into the color gamut triangles corresponding to the image to be displayed, so that the color gamut of the whole picture is not reduced, the whole display image quality is not influenced, and the display effect is ensured.

In one embodiment, dividing an image to be displayed into a plurality of sub-regions, and determining a region color gamut triangle corresponding to each sub-region may include: dividing an image to be displayed into a plurality of sub-areas; determining the position point of the color point of each pixel in each sub-area in the color gamut triangle; and determining the area color gamut triangle corresponding to each subarea according to all the position points corresponding to each subarea.

Exemplarily, the color of the image to be displayed is determined, and thus the color of the color point of each pixel within each sub-area is determined. And analyzing the position coordinates of each color point in the color gamut triangle of the image to be displayed according to the color of the color point of each pixel, wherein the point where the position coordinates are located is the position point of the color point in the color gamut triangle. Thereby, a position point of the color point of the pixels within each sub-area within the color gamut triangle may be determined, each sub-area comprising a plurality of color points and, thus, each sub-area comprising a plurality of position points. For a sub-region, a triangle surrounding all position points of the sub-region can be drawn, the drawn triangle is a region color gamut triangle corresponding to the sub-region, all position points corresponding to the sub-region are located in the region color gamut triangle, and the region color gamut triangle is located in the color gamut triangle of the image to be displayed. Note that the gamut triangles are different for each region.

In one embodiment, controlling the first color light emitting diodes, the second color light emitting diodes, and the third color light emitting diodes in each unit region to be lit so that the unit region displays the color of the corresponding vertex in the corresponding region color gamut triangle may include: calculating the brightness ratios of the first color light-emitting diode, the second color light-emitting diode and the third color light-emitting diode in the corresponding unit region according to the colors of the corresponding vertexes in the color gamut triangles of the regions; determining control signals of the first color light-emitting diode, the second color light-emitting diode and the third color light-emitting diode according to the brightness ratios of the first color light-emitting diode, the second color light-emitting diode and the third color light-emitting diode; and respectively controlling the first color light emitting diode, the second color light emitting diode and the third color light emitting diode to be lightened based on the control signal of the first color light emitting diode, the control signal of the second color light emitting diode and the control signal of the third color light emitting diode.

For example, the color of the corresponding vertex in the area color gamut triangle may be determined by the color gamut range of the image to be displayed, and according to the color of the vertex, the R chromaticity value, the G chromaticity value, and the B chromaticity value corresponding to the color may be determined, so that the luminance ratio of the R light emitting diode, the luminance ratio of the G light emitting diode, and the luminance ratio of the B light emitting diode may be determined.

It is understood that different data voltages can be inputted to the leds to obtain different luminances, and thus, the corresponding data voltages (i.e., control signals) can be determined according to the luminance ratio of the leds. The corresponding control signal is input to the light-emitting diode, so that the light-emitting diode can be controlled to present the brightness of the corresponding proportion.

According to the driving method of the light source module, the light source module is divided into the plurality of unit areas, and each unit area is driven by the area color gamut triangle of the low saturation color gamut, so that the color separation effect can be effectively reduced. In addition, the area color gamut triangles corresponding to all the unit areas can be spliced into the color gamut triangles corresponding to the image to be displayed, so that the color gamut of the whole picture is not reduced, the whole display image quality is not influenced, and the display effect is ensured.
