Background

A display device generally includes a display panel and a driver disposed adjacent to one side (e.g., left side) of the display panel.

Detailed Description

Illustrative and non-limiting example embodiments will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings.

Fig. 1 is a block diagram illustrating a display device according to some example embodiments.

Referring to fig. 1, a display device 1000 according to some example embodiments may include a display panel DPN, a gate driver GDV, a data driver DDV, and a timing controller CON.

A plurality of pixels and a plurality of lines may be disposed in the display panel DPN. The pixels may emit light by receiving signals and/or voltages from the lines.

According to some example embodiments, the display panel DPN may include a plurality of divided driving parts. For example, the display panel DPN may include first to kth (where k is an integer of 2 or more) divided driving parts SDP1 to SDPk. According to some example embodiments, each of the divided driving parts may be formed to be substantially the same. For example, (2n × m) pixels may be disposed in the first divided driving section SDP1, and (2n × m) pixels may be disposed in the k-th divided driving section SDPk. Alternatively, according to some example embodiments, each of the divided driving parts may be formed to be different from each other.

The timing controller CON may generate the gate control signal GCTRL, the data control signal DCTRL, and the output image data ODAT based on the control signal CTRL and the input image data IDAT supplied from the external device. The timing controller CON may be formed on a printed circuit board PCB (see fig. 2). For example, the control signal CTRL may include a vertical synchronization signal, a horizontal synchronization signal, an input data enable signal, a main clock signal, and the like, and the input image data IDAT may be RGB data including red image data, green image data, and blue image data.

The gate driver GDV may generate the gate signal based on the gate control signal GCTRL provided from the timing controller CON. For example, the gate control signal GCTRL may include a vertical start signal and a clock signal.

The gate driver GDV may be electrically connected to the display panel DPN and may sequentially output gate signals. Each of the pixels may receive a data voltage in response to each of the gate signals.

According to some example embodiments, the gate driver GDV may include a partial gate driver corresponding to the divided driving part. For example, the gate driver GDV may include first to kth local gate drivers PGDV1 to PGDVk. The first local gate driver PGDV1 may sequentially output gate signals to the first divided driving part SDP1, and the kth local gate driver PGDVk may sequentially output gate signals to the kth divided driving part SDPk.

The data driver DDV may generate the data voltage based on the data control signal DCTRL and the output image data ODAT supplied from the timing controller CON. For example, the data control signal DCTRL may include an output data enable signal, a horizontal start signal, and a load signal.

The data driver DDV may be electrically connected to the display panel DPN and may generate a data voltage. Each of the pixels may emit light having a luminance corresponding to each of the data voltages. According to some example embodiments, the data driver DDV may include a plurality of data driving circuits.

According to some example embodiments, the pixels may be arranged in a matrix arrangement. Each of the first through k-th divided driving parts SDP1 through SDPk may be divided into a plurality of rows and a plurality of columns. For example, the rows may include first to nth pixel rows PXLr (1) to PXLr (2n) arranged along a first direction D1, and the columns may include first to mth pixel columns PXLc (1) to PXLc (m) arranged along a second direction D2 intersecting the first direction D1. Thus, a pixel of the pixels may be arranged in a pixel row of the pixel rows and a pixel column of the pixel columns.

According to some example embodiments, the first partial gate driver PGDV1 may output a gate signal to pixels disposed in the first divided driving portion SDP 1. For example, the first local gate driver PGDV1 may sequentially output the first to 2 n-th gate signals. The first gate signal may be supplied to the pixels disposed in the first pixel row PXLr (1), and the 2 n-th gate signal may be supplied to the pixels disposed in the 2 n-th pixel row PXLr (2 n).

According to some example embodiments, the kth local gate driver PGDVk may output the gate signal to the pixels disposed in the kth divided driving section SDPk. For example, the kth local gate driver PGDVk may sequentially output the first to 2n gate signals. The first to 2 n-th gate signals may be substantially the same as the first to 2 n-th gate signals output from the first local gate driver PGDV 1.

Fig. 2 is a plan view illustrating the display device of fig. 1.

Referring to fig. 1 and 2, the display apparatus 1000 may be divided into a display area DA provided with a display panel DPN and a non-display area NDA not provided with the display panel DPN.

The display panel DPN may include first to k-th divided driving parts SDP1 to SDPk. For example, 12 pixels may be set in each of the first to k-th divided driving sections SDP1 to SDPk.

According to some example embodiments, the first to twelfth pixels PXL1, PXL2, PXL3, PXL4, PXL5, PXL6, PXL7, PXL8, PXL9, PXL10, PXL11, and PXL12 may be disposed in the first divided drive section SDP 1. For example, the first to fourth pixels PXL1, PXL2, PXL3 and PXL4 may be disposed in the first pixel column PXLc (1), the fifth to eighth pixels PXL5, PXL6, PXL7 and PXL8 may be disposed in the second pixel column PXLc (2), and the ninth to twelfth pixels PXL9, PXL10, PXL11 and PXL12 may be disposed in the third pixel column PXLc (3). In addition, the first, fifth, and ninth pixels PXL1, PXL5, and PXL9 may be disposed in the first pixel row PXLr (1), the second, sixth, and tenth pixels PXL2, PXL6, and PXL10 may be disposed in the second pixel row PXLr (2), the third, seventh, and eleventh pixels PXL3, PXL7, and PXL11 may be disposed in the third pixel row PXLr (3), and the fourth, eighth, and twelfth pixels PXL4, PXL8, and PXL12 may be disposed in the fourth pixel row PXLr (4).

According to some example embodiments, 6 connection lines, 4 gate lines, and 9 data lines may be disposed in each of the first to k-th divided driving parts SDP1 to SDPk. For example, the first to sixth connection lines CL1, CL2, CL3, CL4, CL5 and CL6, the first to fourth gate lines GL1, GL2, GL3, GL4, and the first to ninth data lines DL1, DL2, DL3, DL4, DL5, DL6, DL7, DL8 and DL9 may be disposed in the first divided driving part SDP 1.

According to some example embodiments, each of the connection lines may extend in the first direction D1 and may be spaced apart from each other in the second direction D2. For example, the first and second connection lines CL1 and CL2 may be arranged to correspond to the first pixel column PXLc (1), the third and fourth connection lines CL3 and CL4 may be arranged to correspond to the second pixel column PXLc (2), and the fifth and sixth connection lines CL5 and CL6 may be arranged to correspond to the third pixel column PXLc (3). In other words, the two connection lines may be arranged to correspond to one pixel column among the pixel columns. However, the number of connection lines arranged to correspond to one pixel column is not limited thereto. For example, according to some example embodiments, there may be additional or fewer connecting lines without departing from the spirit and scope of embodiments according to the present disclosure.

Each of the connection lines may electrically connect one of the gate lines and the gate driver GDV. For example, the first connection line CL1 may electrically connect the first gate line GL1 and the first local gate driver PGDV1, the second connection line CL2 may electrically connect the second gate line GL2 and the first local gate driver PGDV1, the third connection line CL3 may electrically connect the third gate line GL3 and the first local gate driver PGDV1, and the fourth connection line CL4 may electrically connect the fourth gate line GL4 and the first local gate driver PGDV 1.

According to some example embodiments, each of the gate lines may extend in the second direction D2 and may be spaced apart from each other in the first direction D1. For example, the first gate lines GL1 may be arranged to correspond to the first pixel row PXLr (1), the second gate lines GL2 may be arranged to correspond to the second pixel row PXLr (2), the third gate lines GL3 may be arranged to correspond to the third pixel row PXLr (3), and the fourth gate lines GL4 may be arranged to correspond to the fourth pixel row PXLr (4).

Each of the gate lines may electrically connect the pixels disposed in one of the pixel rows and the connection line. For example, the first gate line GL1 may electrically connect the first, fifth, and ninth pixels PXL1, PXL5, and PXL9 disposed in the first pixel row PXLr (1) and the first connection line CL1, the second gate line GL2 may electrically connect the second, sixth, and tenth pixels PXL6, and PXL10 disposed in the second pixel row PXLr (2) and the second connection line CL2, the third gate line GL3 may electrically connect the third, seventh, and eleventh pixels PXL3, PXL7, and PXL11 disposed in the third pixel row PXLr (3) and the third connection line CL3, and the fourth gate line GL4 may electrically connect the fourth, eighth, and twelfth pixels PXL6, PXL8, and the twelfth pixel PXL 73727 disposed in the fourth pixel row PXLr (4) and the fourth connection line 12.

According to some example embodiments, each of the data lines may extend in the first direction D1 and may be spaced apart from each other in the second direction D2. For example, the first to third data lines DL1, DL2 and DL3 may be arranged to correspond to the first pixel column PXLc (1), the fourth to sixth data lines DL4, DL5 and DL6 may be arranged to correspond to the second pixel column PXLc (2), and the seventh to ninth data lines DL7, DL8 and DL9 may be arranged to correspond to the third pixel column PXLc (3). In other words, three data lines may be arranged to correspond to one pixel column among the pixel columns. However, the number of data lines arranged corresponding to one pixel column is not limited thereto. For example, according to some example embodiments, there may be additional or fewer data lines without departing from the spirit and scope of embodiments according to the present disclosure.

Each of the data lines may electrically connect the pixels arranged in one of the pixel columns and the data driver DDV. For example, the first data line DL1 may electrically connect the first to fourth pixels PXL1, PXL2, PXL3 and PXL4 arranged in the first pixel column PXLc (1) and the data driver DDV.

The gate driver GDV may be disposed in the non-display area NDA adjacent to the lower side of the display panel DPN.

According to some example embodiments, the gate driver GDV may be installed in the non-display area NDA. The gate driver GDV may include first to kth local gate drivers PGDV1 to PGDVk. The first through kth partial gate drivers PGDV1 through PGDVk may output gate signals to pixels disposed in the first through kth divided driving sections SDP1 through SDPk, respectively.

The data driver DDV may be disposed in the non-display area NDA adjacent to a lower side of the display panel DPN. According to some example embodiments, the data driver DDV may be implemented in the first to kth data driving circuits DIC1 to DICk. In this case, the flexible printed circuit board FPCB may be disposed in the non-display area NDA, and each of the data driving circuits may be integrated on the flexible printed circuit board FPCB. The first to kth data driving circuits DIC1 to DICk may output the data voltages to the pixels disposed in the first to kth divided driving sections SDP1 to SDPk, respectively.

The gate driver GDV and the data driver DDV included in the display device 1000 according to some example embodiments may be disposed in the non-display area NDA adjacent to the lower side of the display panel DPN. In other words, the gate driver GDV may not be disposed in the non-display area NDA adjacent to the left or right side of the display panel DPN. Accordingly, the bezel of the left or right side of the display apparatus 1000 may be reduced.

Meanwhile, the divided driving part, the gate driver, and the data driver included in the display device 1000 are not limited to the above. For example, the number of pixels, connection lines, gate lines, or data lines may be set as desired. In addition, the gate driver may be implemented in a plurality of gate driving circuits, and each of the gate driving circuits may be integrated on the flexible printed circuit board FPCB.

According to some example embodiments, a plurality of high power voltage lines may be disposed in the first divided driving portion SDP 1. For example, the first to third high power voltage lines elvdd 1, elvdd 2, and elvdd 3 may be disposed in the first divided driving portion SDP 1.

According to some example embodiments, each of the high supply voltage lines may extend in the first direction D1 and may be spaced apart from each other in the second direction D2. For example, the first high power voltage line elddl 1 may be disposed to correspond to the first pixel column PXLc (1), the second high power voltage line elddl 2 may be disposed to correspond to the second pixel column PXLc (2), and the third high power voltage line elddl 3 may be disposed to correspond to the third pixel column PXLc (3). In other words, the high power supply voltage line may be arranged to correspond to one pixel column among the pixel columns. However, the number of the high power supply voltage lines arranged to correspond to one pixel column is not limited thereto.

Each of the high power supply voltage lines may transmit a high power supply voltage to a pixel in a pixel column disposed among the pixel columns. For example, the first high power voltage line elddl 1 may transmit the high power voltage to the first to fourth pixels PXL1, PXL2, PXL3, and PXL4 disposed in the first pixel column PXLc (1), the second high power voltage line elddl 2 may transmit the high power voltage to the fifth to eighth pixels PXL5, PXL6, PXL7, and PXL8 disposed in the second pixel column PXLc (2), and the third high power voltage line elddl 3 may transmit the high power voltage to the ninth to twelfth pixels PXL9, PXL10, PXL11, and PXL12 disposed in the third pixel column PXLc (3).

According to some example embodiments, the fifth and sixth connection lines CL5 and CL6 may not be connected to the gate lines. For example, the fifth and sixth connection lines CL5 and CL6 may be dummy lines. Accordingly, a constant voltage may be supplied to the fifth connection line CL5 and the sixth connection line CL 6. Alternatively, the fifth and sixth connection lines CL5 and CL6 may be electrically floating.

For example, fig. 3 may be an enlarged view of region a of fig. 2.

Referring to fig. 2, 3, and 4, the first pixel PXL1 may include first to third sub-pixels SPX1, SPX2, and SPX 3. For example, the first subpixel SPX1 may emit red light, the second subpixel SPX2 may emit green light, and the third subpixel SPX3 may emit blue light. The second pixel PXL2 may have substantially the same structure as the first pixel PXL1 and may be driven in substantially the same driving method.

According to some example embodiments, the first pixel PXL1 may be electrically connected to the first gate line GL 1. The first gate line GL1 may be electrically connected to the first connection line CL1 through the first contact hole CNT 1. Accordingly, the first pixel PXL1 may receive the first gate signal GS 1. In other words, the first pixel PXL1 may receive the first output gate signal from the first local gate driver PGDV 1. For example, the first to third subpixels SPX1, SPX2 and SPX3 included in the first pixel PXL1 may receive the first gate signal GS 1.

According to some example embodiments, the second pixel PXL2 may be electrically connected to the second gate line GL 2. The second gate line GL2 may be electrically connected to the second connection line CL2 through the second contact hole CNT 2. Accordingly, the second pixel PXL2 may receive the second gate signal GS 2. In other words, the second pixel PXL2 may receive the second output gate signal from the first local gate driver PGDV 1. For example, the first to third subpixels SPX1, SPX2 and SPX3 included in the second pixel PXL2 may receive the second gate signal GS 2.

According to some example embodiments, the second connection line CL2 and the first gate line GL1 may not be electrically connected to each other. For example, the contact hole may not be formed in a region where the second connection line CL2 and the first gate line GL1 overlap.
