Abstract
Description
Technical Field
[0001] The present invention relates to the field of display technology, and in particular to a display panel driving method, a driving chip and a display device. Background Art
[0002] The Trigate drive architecture is an important cost-saving drive design for LCD (Liquid Crystal Display). It uses GOA (Gate driver On Array) to increase the number of gate lines by 3 times, which can reduce the number of data lines to 1 / 3 of that of ordinary LCDs to achieve cost savings. In order to further save the cost of the entire machine, LCDs usually use 4Domain VA (4Domain Vertical Alignment) technology to increase the transmittance to save backlight costs. As mentioned above, with the combination of Trigate+4Domain VA, the effective application of viewing angle improvement algorithms is an important requirement for improving image quality.
[0003] In the related art, when the Trigate driver architecture is used with the viewing angle improvement algorithm, severe head shaking wrinkles will occur. Figure 1 As shown, the compensation state of the sub-pixel includes a high grayscale data compensation state (indicated by H) and a low grayscale data compensation state (indicated by L), and the polarity of the sub-pixel includes a positive polarity (indicated by +) and a negative polarity (indicated by -). The human eye is more sensitive to green. Taking the green sub-pixel G with a high grayscale data compensation state H as an example, the polarity of the green sub-pixel G with a high grayscale data compensation state H in two adjacent sub-pixel columns of the first area A1 is negative polarity -, and the polarity of the green sub-pixel G with a high grayscale data compensation state H in two adjacent sub-pixel columns of the second area A2 is positive polarity +. The polarities of the two are completely opposite, so that the polarity difference between the two adjacent sub-pixel columns of the first area A1 and the two adjacent sub-pixel columns of the second area A2 is large.
[0004] The green sub-pixel GH in the first area A1 with high grayscale data compensation and the green sub-pixel GH in the second area A2 with high grayscale data compensation will switch polarity in different frames. In this way, when the head is still, the brightness of the first area and the second area is averaged in time, and the human eye is not easy to detect uneven brightness. However, once the head moves, the time averaging effect is destroyed, and the human eye is easy to detect uneven brightness, resulting in serious head shaking wrinkles. Summary of the invention

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device.
[0024] like Figure 2 As shown, an embodiment of the present invention provides a display device 1. The display device 1 may include a display panel 2, a circuit board 3, and a chip on film (COF) 4. The display panel 2 may be an LCD. The circuit board 3 may be a rigid printed circuit board. The chip on film 4 may be a flexible circuit board.
[0025] The display panel 2 includes a display area DA and a non-display area NDA. The display area DA may be an area for setting a sub-pixel SPX for displaying an image. The non-display area NDA may be an area for setting a driving unit for providing a driving signal to the sub-pixel SPX and some lines such as a power line connecting the driving unit. The non-display area NDA may be set on at least one side of the display area DA. The non-display area NDA may at least partially surround the periphery of the display area DA.
[0026] The display panel 2 includes a plurality of sub-pixels SPX, a plurality of data lines DT, a plurality of scan lines SN, and a gate drive circuit GDC. The plurality of sub-pixels SPX are located in the display area DA. The gate drive circuit GDC is located in the non-display area NDA, and drives a plurality of rows of sub-pixels SPX through a plurality of scan lines SN to turn on a plurality of rows of sub-pixels SPX row by row. At the same time, the plurality of data lines DT sequentially load data signals to a plurality of rows of sub-pixels SPX, so that the display panel 2 displays a complete frame of images within a frame.
[0027] The chip-on-film 4 includes a source driver chip 41 for transmitting the data signal to the plurality of data lines DT.
[0028] The circuit board 3 includes a timing control chip 31. The timing control chip 31 is electrically connected to the source driver chip 41 and the gate driver circuit GDC to control their timing.
[0029] like Figure 3-5 As shown, a plurality of sub-pixels SPX are arranged along the intersecting row direction and column direction to form a plurality of sub-pixel rows SPXR arranged in the column direction, and a plurality of sub-pixel columns SPXC arranged in the row direction. The plurality of sub-pixels SPX include a plurality of first sub-pixels B, a plurality of second sub-pixels G, and a plurality of third sub-pixels R, and the plurality of sub-pixel rows SPXR include a plurality of first sub-pixel rows, a plurality of second sub-pixel rows, and a plurality of third sub-pixel rows arranged alternately. Optionally, the first sub-pixel B is a blue sub-pixel, the second sub-pixel G is a green sub-pixel, and the third sub-pixel R is a red sub-pixel. Of course, the types of the first sub-pixel B, the second sub-pixel G, and the third sub-pixel R are not limited thereto. Among them, the display colors of the plurality of sub-pixels SPX in the same sub-pixel row SPXR are the same, and the display colors of the plurality of sub-pixels SPX in the adjacent sub-pixel rows SPXR are different. That is, the plurality of sub-pixels SPX form a Trigate drive architecture.
[0030] Each of the sub-pixel columns SPXC includes a plurality of sub-pixel groups SPXG, and the plurality of sub-pixel groups SPXG include a sub-pixel group SPXG1 (i.e., a first sub-pixel group), a sub-pixel group SPXG2 (i.e., a second sub-pixel group), and a sub-pixel group SPXG3 (i.e., a third sub-pixel group), and the sub-pixel group SPXG2 is located between the sub-pixel group SPXG1 and the sub-pixel group SPXG3. The sub-pixel group SPXG1 and the sub-pixel group SPXG3 are connected to a corresponding one of the data lines DL. The sub-pixel group SPXG2 includes 2n sub-pixels SPX, and the sub-pixel group SPXG2 is connected to another adjacent data line DL. n is an integer, for example, n is 0 or a positive integer. That is, the present embodiment provides a new design for flipping the pixel polarity by spacing an even number of sub-pixels SPX in each pixel column.
[0031] Based on the above new design, in the same frame, among the multiple sub-pixels SPX having the same display color and a high grayscale data compensation state H in any group of two adjacent sub-pixel columns SPXC, the polarity of at least one sub-pixel SPX is different from that of the other sub-pixels SPX.
[0032] In this way, this embodiment provides a new design for flipping the pixel polarity by spacing an even number of sub-pixels SPX in each pixel column for the Trigate driving architecture, so that in any group of two adjacent sub-pixel columns SPXC, the polarities of the multiple sub-pixels SPX with the same display color and a high grayscale data compensation state H will not be all positive + or negative -, thereby reducing the polarity difference between the multiple sub-pixels SPX with the same display color and a high grayscale data compensation state H in the four adjacent sub-pixel columns SPXC, thereby improving the phenomenon that when the head moves, the human eye perceives the brightness change caused by the polarity change in the area with a large polarity difference and perceives the head shake wrinkles.
[0033] [Example 1]
[0034] See also Figure 3 In this embodiment, n is a positive integer, such as 1. That is, in each of the sub-pixel columns SPXC, the pixel polarity is flipped every two sub-pixels SPX.
[0035] Each of the sub-pixel columns SPXC includes a plurality of sub-pixel groups SPXG, and each of the sub-pixel groups SPXG includes 2 (i.e., 2n) sub-pixels SPX. The plurality of sub-pixel groups SPXG include a sub-pixel group SPXG1 (i.e., a first sub-pixel group), a sub-pixel group SPXG2 (i.e., a second sub-pixel group), and a sub-pixel group SPXG3 (i.e., a third sub-pixel group), and the sub-pixel group SPXG2 is located between the sub-pixel group SPXG1 and the sub-pixel group SPXG3. Each of the sub-pixel columns SPXC is connected between two adjacent data lines DL. A sub-pixel group SPXG is provided between each two sub-pixel groups SPXG connected to one of the data lines DL, and the sub-pixel group SPXG is connected to another adjacent data line DL. The polarities of the plurality of sub-pixels SPX of the plurality of sub-pixel groups SPXG connected to the same data line DL are the same, and the polarities of the plurality of sub-pixels SPX of the plurality of sub-pixel groups SPXG connected to two adjacent data lines DL are opposite. Thus, this embodiment provides a new design for flipping the polarity of pixels by 2 sub-pixels SPX in each pixel column.
[0036] In the same sub-pixel column SPXC, the grayscale data compensation states of two adjacent sub-pixels SPX are opposite. For example, in the first three sub-pixels SPX in the last sub-pixel column SPXC, the grayscale data compensation states of the first sub-pixel B, the second sub-pixel G, and the third sub-pixel R are respectively low grayscale data compensation state L, high grayscale data compensation state H, and low grayscale data compensation state L. In the same sub-pixel row SPXR, the grayscale data compensation states of two adjacent sub-pixels SPX are repeated in the opposite and same order. For example, in the first six sub-pixels SPX in the first sub-pixel row SPXR, the grayscale data compensation states of the six sub-pixels SPX are respectively low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, and high grayscale data compensation state H.
[0037] Among the plurality of sub-pixels SPX in the same sub-pixel column SPXC that display the same color and have the high grayscale data compensation state H, the polarities of two adjacent sub-pixels SPX are opposite. For example, among the plurality of second sub-pixels G in the first sub-pixel column SPXC that have the high grayscale data compensation state H, the polarities of the plurality of second sub-pixels G are negative polarity -, positive polarity +, respectively.
[0038] In this way, in any group of two adjacent sub-pixel columns SPXC, the polarity of the plurality of sub-pixels SPX with the same display color and high grayscale data compensation state H will not be positive + or negative -, which reduces the polarity difference between the plurality of sub-pixels SPX with the same display color and high grayscale data compensation state H in the four adjacent sub-pixel columns SPXC, thereby improving the shaking head wrinkle phenomenon observed by the human eye due to the large polarity difference of the region when the head moves. For example, among the plurality of second sub-pixels G with high grayscale data compensation state H in the first and second columns of the sub-pixel columns SPXC, the polarity of the second sub-pixel G in the first column is negative - and positive +, and the polarity of the second sub-pixel G in the second column is positive + and negative -.
[0039] Furthermore, when the sub-pixels SPX with the same display color and high grayscale data compensation state H are lit in the same frame to display the same grayscale, the absolute values of the average effective voltages of the two adjacent data lines DL are the same. For example, when the green sub-pixel with high grayscale data compensation state H is lit in the same frame, the voltage of the first data line DL can be expressed as: 0-(H-)-0-0-0-0-0-(H-)-0-0-0-0-0…, and the voltage of the second data line DL can be expressed as: 0-0-0-0-(H+)-0-0-(H+)-0-0-0-0-0…, therefore, the average effective voltages of the first data line DL and the second data line DL in the same frame are the same in magnitude but opposite in polarity. In this way, the probability of vertical crosstalk can be effectively reduced.
[0040] [Example 2]
[0041] See also Figure 4 This embodiment is similar to the embodiment 1, except that: in this embodiment, n is 2. That is, in each of the sub-pixel columns SPXC, the pixel polarity is flipped every 4 sub-pixels SPX. In other embodiments, n can be 3, 4, 5, ...
[0042] In this way, in any group of two adjacent sub-pixel columns SPXC, the polarity of the plurality of sub-pixels SPX with the same display color and high grayscale data compensation state H will not be positive + or negative -, which reduces the polarity difference between the plurality of sub-pixels SPX with the same display color and high grayscale data compensation state H in the four adjacent sub-pixel columns SPXC, thereby improving the shaking head wrinkle phenomenon observed by the human eye due to the large polarity difference of the region when the head moves. For example, among the plurality of second sub-pixels G with high grayscale data compensation state H in the first and second columns of the sub-pixel columns SPXC, the polarity of the second sub-pixel G in the first column is negative - and positive +, and the polarity of the second sub-pixel G in the second column is negative + and positive +.
[0043] [Example 3]
[0044] See also Figure 5 In this embodiment, n is 0. Since n=0, the original second sub-pixel group does not exist, so that each sub-pixel column SPXC is connected to a corresponding data line DL. The polarities of the sub-pixels SPX of the sub-pixel groups SPXG connected to the same data line DL are the same, and the polarities of the sub-pixels SPX of the sub-pixel groups SPXG connected to two adjacent data lines DL are opposite. In this way, this embodiment provides a new design in which the polarities of the sub-pixels SPX of the same sub-pixel column SPXC are the same.
[0045] In the same sub-pixel column SPXC, the grayscale data compensation states of two adjacent sub-pixels SPX are opposite. For example, in the first three sub-pixels SPX in the first column of sub-pixel column SPXC, the grayscale data compensation states of the first sub-pixel B, the second sub-pixel G, and the third sub-pixel R are respectively low grayscale data compensation state L, high grayscale data compensation state H, and low grayscale data compensation state L. In the same sub-pixel row SPXR, the grayscale data compensation states of two adjacent sub-pixels SPX are repeated in the opposite and same order. For example, in the first six sub-pixels SPX in the first row of sub-pixel row SPXR, the grayscale data compensation states of the six sub-pixels SPX are respectively low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, and high grayscale data compensation state H.
[0046] In this way, in any group of two adjacent sub-pixel columns SPXC, the polarity of the plurality of sub-pixels SPX with the same display color and high grayscale data compensation state H will not be positive + or negative -, which reduces the polarity difference between the plurality of sub-pixels SPX with the same display color and high grayscale data compensation state H in the four adjacent sub-pixel columns SPXC, thereby improving the shaking head wrinkle phenomenon observed by the human eye due to the large polarity difference of the region when the head moves. For example, among the plurality of second sub-pixels G with high grayscale data compensation state H in the first and second columns of the sub-pixel columns SPXC, the polarity of the second sub-pixel G in the first column is negative -, negative -, and the polarity of the second sub-pixel G in the second column is positive +, positive +.
[0047] Furthermore, when the sub-pixels SPX with the same display color and high grayscale data compensation state H are lit in the same frame to display the same grayscale, the absolute values of the average effective voltages of the two adjacent data lines DL are the same. For example, when the green sub-pixel with high grayscale data compensation state H is lit in the same frame, the voltage of the first data line DL can be expressed as: 0-(H-)-0-0-0-0-0-(H-)-0-0-0-0-0…, and the voltage of the second data line DL can be expressed as: 0-0-0-0-(H+)-0-0-(H+)-0-0-0-0-0…, therefore, the average effective voltages of the first data line DL and the second data line DL in the same frame are the same in magnitude but opposite in polarity. In this way, the probability of vertical crosstalk can be effectively reduced.
[0048] [Example 4]
[0049] See also Figure 6 The embodiment of the present invention further provides a display panel driving method, which is applied to the display module 1 as described above to drive the display panel 2. The driving method can be implemented by the source driver chip 41 by executing corresponding program instructions. The driving method includes:
[0050] S1, driving the plurality of sub-pixels SPX to display in a plurality of frames.
[0051] Each of the sub-pixels SPX has a high grayscale data compensation state H and a low grayscale data compensation state L within the multiple frames, and has a positive polarity + and a negative polarity -.
[0052] Each of the sub-pixel columns SPXC includes a plurality of sub-pixel groups SPXG, 2n sub-pixels SPX are arranged between each two sub-pixel groups SPXG connected to the corresponding data lines DL, and 2n sub-pixels SPX are connected to another adjacent data line DL, where n is an integer. That is, this embodiment provides a new design for flipping the polarity of pixels by spacing an even number of sub-pixels SPX in each pixel column.
[0053] Based on the above new design, in the same frame, among the multiple sub-pixels SPX having the same display color and a high grayscale data compensation state H in any group of two adjacent sub-pixel columns SPXC, the polarity of at least one sub-pixel SPX is different from that of the other sub-pixels SPX.
[0054] In this way, in any group of two adjacent sub-pixel columns SPXC, the phenomenon that the polarities of the multiple sub-pixels SPX that display the same color and have the high grayscale data compensation state H are all positive + or negative - will not occur, thereby reducing the polarity difference between the multiple sub-pixels SPX that display the same color and have the high grayscale data compensation state H in the four adjacent sub-pixel columns SPXC, thereby improving the shaking head wrinkle phenomenon observed by the human eye due to the large difference in polarity of the region when the head moves.
[0055] In addition, the polarities of the sub-pixels SPX of the sub-pixel groups PXG are reversed every p frames, where p is a positive integer, such as 1, 2, or 3. In this way, polarity symmetry in the time dimension can be achieved.
[0056] [Example 5]
[0057] An embodiment of the present invention further provides a driver chip configured to execute program instructions to implement the above-mentioned driving method. Specifically, the driver chip may be a source driver chip or a timing control chip.
[0058] Thus, within the same frame, among the plurality of sub-pixels SPX having the same display color and a high grayscale data compensation state H in any group of two adjacent sub-pixel columns SPXC, the polarity of at least one sub-pixel SPX is different from that of the other sub-pixels SPX.
[0059] In this way, in any group of two adjacent sub-pixel columns SPXC, the phenomenon that the polarities of the multiple sub-pixels SPX that display the same color and have the high grayscale data compensation state H are all positive + or negative - will not occur, thereby reducing the polarity difference between the multiple sub-pixels SPX that display the same color and have the high grayscale data compensation state H in the four adjacent sub-pixel columns SPXC, thereby improving the shaking head wrinkle phenomenon observed by the human eye due to the large difference in polarity of the region when the head moves.
