Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Example one

Referring to fig. 1, a schematic diagram of a multiplexing register of an embodiment of the present invention is shown.

The embodiment of the invention provides a multiplexing register 11, which is applied to a three-dimensional display device, wherein the multiplexing register 11 comprises a multiplexing module 111, and the multiplexing module 111 comprises an instruction output unit, a parameter output unit and an address output unit; an instruction output unit configured to output instruction execution data corresponding to each instruction operation when the multiplexing module 111 is in an instruction execution state; a parameter output unit configured to output configuration data for performing parameter configuration on the three-dimensional display apparatus when the multiplexing module 111 is in a data operation state; an address output unit configured to output address data related to an entry address of the two-dimensional image slice when the multiplexing module 111 is in an address synthesis state; at any time, the multiplexing module 111 is in any one of an instruction execution state, a data operation state and an address synthesis state.

In the embodiment of the present invention, at any time, the multiplexing register 11 may be any one of an instruction register, a data register and an address register, that is, at any time, the multiplexing module 111 in the multiplexing register 11 is in any one of an instruction execution state, a data operation state and an address synthesis state; when the multiplexing register 11 is used as an instruction register, the multiplexing module 111 in the multiplexing register 11 is in an instruction execution state, and at this time, instruction execution data corresponding to each instruction operation is stored in the multiplexing module 111; when the multiplexing register 11 is used as a data register, the multiplexing module 111 in the multiplexing register 11 is in a data operation state, and at this time, configuration data for performing parameter configuration on the three-dimensional display device is stored in the multiplexing module 111; when the multiplexing register 11 is used as an address register, the multiplexing module 111 in the multiplexing register 11 is in an address synthesis state, and at this time, address data related to an entry address of the two-dimensional image slice is stored in the multiplexing module 111.

And, the multiplexing module 111 can switch between any two operation states of an instruction execution state, a data operation state and an address synthesis state, and the rule of the operation state switching is related to the execution code written by the programmer and whether the device in the three-dimensional display device is in failure or not.

For example, after the three-dimensional display device is powered on, the multiplexing module 111 in the multiplexing register 11 is in an instruction execution state, the processor reads instruction execution data for power on self-test stored in the multiplexing module 111 at this time, and after the power on self-test is completed, data stored in the multiplexing module 111 is modified, the instruction execution data is modified into address data, so that the multiplexing module 111 is switched from the instruction execution state to the address synthesis state; or, after the power-on self-test is completed, the data stored in the multiplexing module 111 is modified, and the instruction execution data is modified into the configuration data, so that the multiplexing module 111 is switched from the instruction execution state to the data operation state.

Of course, if the configuration data or the address data is currently stored in the multiplexing module 111, when the three-dimensional display device has a fault, for example, the temperature of a certain device in the three-dimensional display device exceeds a set temperature threshold, and the system of the three-dimensional display device fails to update, the configuration data or the address data stored in the multiplexing module 111 is modified into the instruction execution data, so that the multiplexing module 111 is switched from the data operation state or the address synthesis state to the instruction execution state.

The instruction execution data is used for determining instruction operations to be executed, such as power-on self-test, interrupt priority, system fault processing and the like; the configuration data is used for determining how parameter configuration is required for the three-dimensional display device, such as configuring parameters of color depth, refresh rate and resolution of a display panel in the three-dimensional display device; the address data is used for determining the entrance address of the two-dimensional image slice required to be displayed by the rotary display module.

The three-dimensional display device comprises a rotary display module, wherein the rotary display module comprises a display panel and a driving mechanism, the driving mechanism is connected with the display panel and is used for controlling the display panel to rotate by taking a driving shaft as a center, the driving shaft can be a center line of the display panel, the display panel is used for displaying corresponding two-dimensional image slices according to a rotating position, and each time the display panel rotates for a certain angle, one frame of two-dimensional image slices are switched to be displayed.

By utilizing the human eye vision retention effect, when the driving mechanism controls the display panel to rotate rapidly, a plurality of two-dimensional image slices can be simultaneously reserved in human eyes, so that a viewer can watch an image with a three-dimensional effect; wherein the rotation frequency of the display panel is greater than or equal to 10Hz, and the refresh frequency of the two-dimensional image slice displayed on the display panel is greater than or equal to 60 Hz.

For example, a rotation of the display panel is divided into 16 positions, namely, an angle 1 position, an angle 2 position, and a position up to an angle 16 position, the display panel displays the two-dimensional image slice 1 when the display panel is at the angle 1 position, the display panel displays the two-dimensional image slice 2 when the display panel is rotated from the angle 1 position to the angle 2 position, and so on, and the display panel displays the two-dimensional image slice 16 when the display panel is rotated from the angle 15 position to the angle 16 position. When the display panel is single-sided display, the number of frames of the two-dimensional image slices displayed by the display panel rotating for one circle is r frames/circle, for a viewer watching at any position, 2/r frames of the two-dimensional image slices can be seen, and a three-dimensional image watched by the viewer is formed by the 2/r frames of the two-dimensional image slices; when the display panel is in double-sided display, the number of frames of the two-dimensional image slices displayed by the display panel rotating for one circle is r frames/circle, for a viewer watching at any position, the r frames of the two-dimensional image slices can be seen, and a three-dimensional stereo image watched by the viewer is formed by the r frames of the two-dimensional image slices together.

It should be noted that, the multiplexing register 11 in the embodiment of the present invention is applied to a three-dimensional display device, and a command register, a data register and an address register are replaced by a multiplexing register, mainly because after a rotating display module in the three-dimensional display device rotates one angle to display a frame of two-dimensional image slice, the two-dimensional image slice at the previous angle is not needed to be reused subsequently, that is, the two-dimensional image slice at the previous angle can be discarded, and the two-dimensional image slice in the three-dimensional display device has a discardability, so that it is possible for the multiplexing register 11 to switch between a command execution state, a data operation state and an address synthesis state without affecting normal display of the two-dimensional image slice; the conventional display apparatus is not suitable for using one multiplexing register instead of the instruction register, the data register, and the address register because the image in the conventional display apparatus is not discardable.

For example, in a conventional display device, an image of a current frame needs to be predicted from images of previous frames to complete display, and therefore, after the previous frames of images are displayed, the previous frames of images need to be retained and cannot be discarded.

Referring to fig. 2, a schematic diagram of a multiplexing module according to an embodiment of the present invention is shown.

In the embodiment of the present invention, the bit width of the multiplexing module 111 is 8 bits, and from high to low, the multiplexing module is respectively a seventh bit 7th, a sixth bit 6th, a fifth bit 5th, a fourth bit 4th, a third bit 3th, a second bit 2nd, a first bit 1st, and a 0th bit.

The seventh bit 7th and the sixth bit 6th of the multiplexing module 111 store operation status data, where the operation status data is used to indicate an operation status of the multiplexing module 111, and the operation status includes an instruction execution status, a data operation status, and an address synthesis status.

When the operation state data stored in the seventh bit 7th and the sixth bit 6th of the multiplexing module 111 is 00, determining that the multiplexing module 111 is in the instruction execution state; when the operation state data stored in the seventh bit 7th and the sixth bit 6th of the multiplexing module 111 is 01, determining that the multiplexing module 111 is in a data operation state; when the operation state data stored in the seventh bit 7th and the sixth bit 6th of the multiplexing module 111 is 10, determining that the multiplexing module 111 is in the address synthesis state; of course, if the seventh bit 7th and the sixth bit 6th of the multiplexing module 111 store 11 of the operation status data, this function of the multiplexing module 111 is not used, and of course, a corresponding function may be added subsequently.

In addition, the fifth bit 5th to the 0th bit 0th of the multiplexing module 111 store the operation option and the identification data, and when the operation status data stored in the seventh bit 7th and the sixth bit 6th of the multiplexing module 111 are different, the specific meanings corresponding to the operation option and the identification data stored in the fifth bit 5th to the 0th bit 0th of the multiplexing module 111 are different, which specifically includes the following three cases.

In the first case: when the multiplexing module 111 is in the instruction execution state, the fifth bit 5th to the third bit 3th of the multiplexing module 111 store operation data that needs to be executed in the instruction execution data, the second bit 2nd to the 0th of the multiplexing module store execution parameters corresponding to the operation data, and the execution parameters include direct execution or jump to the initial state.

When the operation status data stored in the seventh bit 7th and the sixth bit 6th of the multiplexing module 111 is 00, it is determined that the multiplexing module 111 is in the instruction execution state, and the fifth bit 5th to the third bit 3th of the multiplexing module 111 store the operation data to be executed in the instruction execution data. When the operation data stored in the fifth bit 5th to the third bit 3th of the multiplexing module 111 is 000, determining that the instruction operation to be executed is a preprocessing operation; when the operation data stored in the fifth bit 5th to the third bit 3th of the multiplexing module 111 is 001, determining that the instruction operation to be executed is a power-on self-test operation; when the operation data stored in the fifth bit 5th to the third bit 3th of the multiplexing module 111 is 010, determining that the instruction operation to be executed is an interrupt priority operation; when the operation data stored in the fifth bit 5th to the third bit 3th of the multiplexing module 111 is 011, determining that the instruction operation to be executed is a system fault handling operation; when the operation data stored in the fifth bit 5th to the third bit 3th of the multiplexing module 111 is 100, determining that the instruction operation to be executed is a reset or power-off operation; of course, if the operation data stored in the fifth bit 5th to the third bit 3th of the multiplexing module 111 is 101, 110 or 111, this indicates that this function of the multiplexing module 111 is not used, and of course, corresponding functions may be added subsequently.

Correspondingly, when the multiplexing module 111 is determined to be in the instruction execution state, the second bit 2nd to the 0th bit of the multiplexing module store the execution parameters corresponding to the operation data, and the execution parameters include direct execution or jump to the initial state. When the execution parameters corresponding to the operation data stored in the second bit 2nd to the 0th bit 0th of the multiplexing module are 00, determining that the execution parameters are directly executed, and directly executing the instruction operation corresponding to the operation data; when the execution parameter corresponding to the operation data stored in the second bit 2nd to the 0th bit 0th of the multiplexing module is 01, it is determined that the execution parameter is in a jump-to-initial state, and the data stored in the multiplexing module 111 is directly modified into initial data, where the initial data is pre-programmed in the manufacturing of the multiplexing register 11.

In the second case: when the multiplexing module 111 is in the data operation state, the fifth bit 5th to the fourth bit 4th of the multiplexing module 111 store the mode data in the configuration data, and the third bit 3th to the 0th of the multiplexing module 111 store the setting parameters corresponding to the mode data.

When the operation status data stored in the seventh bit 7th and the sixth bit 6th of the multiplexing module 111 is 01, it is determined that the multiplexing module 111 is in the data operation status, and the fifth bit 5th to the fourth bit 4th of the multiplexing module 111 store the mode data in the configuration data. When the mode data stored in the fifth bit 5th to the fourth bit 4th of the multiplexing module 111 is 00, determining that the multiplexing module 111 is in the pixel mode; when the pattern data stored in the fifth bit 5th to the fourth bit 4th of the multiplexing module 111 is 01, determining that the multiplexing module 111 is in the calculation mode; when the fifth bit 5th to the fourth bit 4th of the multiplexing module 111 store the pattern data of 10, it is determined that the multiplexing module 111 is in the calibration mode.

Correspondingly, when the multiplexing module 111 is in the pixel mode, the third bit 3th to the 0th bit of the multiplexing module 111 store setting parameters corresponding to the pixel mode, such as color depth, refresh rate, resolution, and the like; when the multiplexing module 111 is in the calculation mode, the third bit 3th to the 0th of the multiplexing module 111 stores a configuration formula coefficient, where the configuration formula coefficient refers to a coefficient used for calculating a specific gray value of a pixel of a two-dimensional image slice, and because when the two-dimensional image slice is stored, in order to reduce an occupied space of the two-dimensional image slice, the two-dimensional image slice is not completely stored according to the gray value of each pixel, and it is necessary to calculate the gray value of one pixel according to the gray value of the relevant pixel, for example, the gray value of the next pixel needs to be calculated according to the gray value of the previous pixel multiplied by the configuration formula coefficient, and if the gray value of the previous pixel is gray10 and the configuration formula coefficient is 4, the gray value of the next pixel is calculated to be gray 40; when the multiplexing module 111 is in the calibration mode, the third bit 3th to the 0th bit of the multiplexing module 111 stores correction parameters, such as Gamma (Gamma) correction parameters, color correction parameters, and the like, and marks a correction address.

In the third case: when the multiplexing module 111 is in the address synthesis state, the fifth bit 5th of the multiplexing module 111 stores address change mode data in the address data; when the address change mode data is the equal interval gradient data, the fourth bit 4th to the 0th bit of the multiplexing module 111 store step sizes, and when the address change mode data is the scattered distribution data, the fourth bit 4th to the 0th bit of the multiplexing module 111 store the indication data for indicating the entry address of the next frame of two-dimensional image slice.

When the operation status data stored in the seventh bit 7th and the sixth bit 6th of the multiplexing module 111 is 10, it is determined that the multiplexing module 111 is in the address synthesis state, and the fifth bit 5th of the multiplexing module 111 stores the address change mode data in the address data. When the address change mode data stored in the fifth bit 5th of the multiplexing module 111 is 0, that is, the address change mode data is the equal interval tapered data, the fourth bit 4th to the 0th bit of the multiplexing module 111 store the step size, that is, the change interval of the address; when the address change manner data stored in the fifth bit 5th of the multiplexing module 111 is 1, that is, the address change manner data is the scattered distribution data, the fourth bit 4th to the 0th bit of the multiplexing module 111 store the indication data for indicating the entry address of the two-dimensional image slice of the next frame, and the indication data is used for indicating the location where the entry address of the two-dimensional image slice is stored.

For example, if the address change pattern data is equal interval gradient data and the step size is 2, if the instruction data of the entry address of the first frame two-dimensional image slice is 1, the instruction data of the entry address of the second frame two-dimensional image slice is 3, if the address change pattern data is not changed, the instruction data of the entry address of the third frame two-dimensional image slice is 5, and so on.

As shown in fig. 1, the multiplexing register 11 further includes an address storage block 112; an address storage module 112 configured to store an entry address of a current two-dimensional image slice and an entry address of a next frame two-dimensional image slice.

When the multiplexing module 111 is in an address synthesis state, address data related to an entry address of a two-dimensional image slice is output, and the processor can determine indicating data for indicating the entry address of the two-dimensional image slice according to the address data, specifically, if address change mode data in the address data is equal-interval tapered data, the step length is directly added according to the indicating data of the entry address of the current two-dimensional image slice to obtain indicating data of the entry address of the next frame of two-dimensional image slice; if the address change mode data in the address data is scattered data, directly acquiring data from the fourth bit 4th to the 0th bit in the address data to obtain indicating data; the processor then obtains the entry address of the two-dimensional image slice according to the indication data, writes the entry address of the current two-dimensional image slice and the entry address of the next two-dimensional image slice into the address storage module 112 in the multiplexing register 11, and the address storage module 112 stores the entry address of the current two-dimensional image slice and the entry address of the next two-dimensional image slice.

It should be noted that the instruction data of the entry address of the first frame of two-dimensional image slice is determined by the execution code written by the programmer, the instruction data of the entry address of the second frame of two-dimensional image slice is determined according to the address data stored in the multiplexing module 111, so as to determine the instruction data of the entry addresses of all the two-dimensional image slices, and the entry address of the two-dimensional image slice is obtained according to the instruction data, so as to ensure normal display of the two-dimensional image slice.

As shown in fig. 1, the multiplexing register 11 further includes an error correction module 113, and the error correction module 113 includes a data modification unit; and the data modification unit is configured to modify the data stored in the multiplexing module 111 to enable the multiplexing module 111 to output instruction execution data for resetting or powering off the three-dimensional display device when the number of times that any one device in the three-dimensional display device executes the same operation is greater than a set number of times.

If the number of times that any device in the three-dimensional display device executes the same operation is greater than the set number of times, that is, the device has a fault, an execution instruction has an endless loop, a data modification unit in the error correction module 113 modifies data stored in the multiplexing module 111, for example, modifies data stored in the multiplexing module 111 into instruction execution data 00100xx, so that the multiplexing module 111 outputs instruction execution data 00100xx for resetting or powering off the three-dimensional display device, and then executes resetting or powering off according to the instruction execution data 00100xx, wherein the data in 'xx' can be selected to execute software resetting or hardware resetting and control the power off of the whole device or the power off of the local device, and if the power off of the local device is present, the power off of the display panel can be controlled, but the driving mechanism is not powered off.

In addition, the error correction module 113 further includes a parameter passing unit; a parameter passing unit configured to pass the join parameter of a plurality of multiplexing registers cascaded with the multiplexing register.

In the three-dimensional display device, a plurality of cascaded multiplexing registers 11 may be provided, and the error correction module 113 may also pass the concatenation parameters of a plurality of multiplexing registers 11 cascaded with any multiplexing register 11, such as passing the entry of the cascaded lower multiplexing register 11, in addition to ensuring normal device performance.

The provided multiplexing register can realize the functions of an instruction register, a data register and an address register to replace the instruction register, the data register and the address register which are arranged in the conventional three-dimensional display device, so that the number of registers required to be arranged in the three-dimensional display device is reduced, the less the registers required to be traversed by the processor are, the resource occupation of the registers on the processor can be correspondingly reduced, and the power consumption of the processor is reduced.
