Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically to a driving method, driving chip, and display device for a display panel. Background Technology

[0002] The Trigate driving architecture is an important cost-saving driving design for LCD (Liquid Crystal Display) panels. It utilizes GOA (Gate driver on Array) to triple the number of gate lines, reducing the number of data lines to one-third that of a standard LCD, thus saving costs. To further reduce overall costs, LCDs typically use 4Domain VA (4Domain Vertical Alignment) technology to improve transmittance and reduce backlight costs. As mentioned above, with the Trigate + 4Domain VA combination, effectively applying viewing angle improvement algorithms is crucial for improving image quality.

[0003] In related technologies, the Trigate driver architecture, when paired with perspective improvement algorithms, exhibits severe head-shaking patterns. For example... Figure 1 As shown, the compensation states of subpixels include high grayscale data compensation states (indicated by H) and low grayscale data compensation states (indicated by L), and the polarity of subpixels includes positive polarity (indicated by +) and negative polarity (indicated by -). The human eye is more sensitive to green. Taking a green subpixel G with a high grayscale data compensation state H as an example, the polarity of the green subpixel G with a high grayscale data compensation state H in the two adjacent subpixel columns of the first region A1 is negative (-), while the polarity of the green subpixel G with a high grayscale data compensation state H in the two adjacent subpixel columns of the second region A2 is positive (+). The polarities of the two are completely opposite, resulting in a significant difference in polarity between the two adjacent subpixel columns of the first region A1 and the two adjacent subpixel columns of the second region A2.

[0004] The green sub-pixel GH with high grayscale data compensation in region A1 and region A2 switch polarity within different frames. Thus, when the head is stationary, the brightness of the first and second regions is averaged over time, making uneven brightness difficult for the human eye to detect. However, once the head moves, the time averaging effect is disrupted, and the uneven brightness becomes easily noticeable, resulting in pronounced head-shaking wrinkles. Summary of the Invention

[0005] This invention provides a driving method and display device for a display panel to improve the technical problem of severe head-shaking wrinkles.

[0006] An embodiment of the present invention provides a driving method for a display panel, wherein the display panel includes a plurality of data lines and a plurality of sub-pixels electrically connected to the plurality of data lines; the plurality of sub-pixels include a plurality of first sub-pixels, a plurality of second sub-pixels, and a plurality of third sub-pixels, the plurality of sub-pixels being arranged along intersecting row and column directions to form a plurality of sub-pixel rows arranged in the column direction and a plurality of sub-pixel columns arranged in the row direction, the plurality of sub-pixel rows including a plurality of alternating first sub-pixel rows, a plurality of second sub-pixel rows, and a plurality of third sub-pixel rows, the plurality of sub-pixels in the same sub-pixel row having the same display color, and the display colors of the sub-pixels in the first sub-pixel row, the second sub-pixel row, and the third sub-pixel row being different; the driving method includes: driving Multiple sub-pixels are displayed across multiple frames. Each sub-pixel has one of a high grayscale data compensation state and a low grayscale data compensation state within each frame, and has one of a positive polarity and a negative polarity. Each sub-pixel column includes multiple sub-pixel groups, which include a first sub-pixel group, a third sub-pixel group, and a second sub-pixel group located between the first and third sub-pixel groups. The first and third sub-pixel groups are connected to a corresponding data line. The second sub-pixel group includes 2n sub-pixels and is connected to an adjacent data line, where n is an integer greater than or equal to 0. Within the same frame, among the multiple sub-pixels in any two adjacent sub-pixel columns that have the same display color and a high grayscale data compensation state, at least one sub-pixel has a polarity different from the other sub-pixels.

[0007] In some embodiments, n is a positive integer, and each sub-pixel group includes 2n sub-pixels.

[0008] In some embodiments, the polarities of the sub-pixels of the multiple sub-pixel groups connected to the same data line are the same, and the polarities of the multiple sub-pixel groups connected to the same data line are opposite to the polarities of the multiple sub-pixel groups connected to an adjacent data line.

[0009] In some embodiments, n=1, and among the multiple sub-pixels in the same sub-pixel column that have the same display color and a high grayscale data compensation state, the polarities of two adjacent sub-pixels are opposite.

[0010] In some embodiments, within the same frame, when the sub-pixels with the same display color and a high grayscale data compensation state are in an luminous state to display the same grayscale, the absolute values ​​of the average effective voltages of two adjacent data lines are the same.

[0011] In some embodiments, n = 0, each sub-pixel column is connected to a corresponding data line; the polarity of the sub-pixels of the multiple sub-pixel groups connected to the same data line is the same, and the polarity of the multiple sub-pixels of the multiple sub-pixel groups connected to the same data line is opposite to the polarity of the multiple sub-pixel groups connected to an adjacent data line.

[0012] In some embodiments, in the same sub-pixel column, the grayscale data compensation states of two adjacent sub-pixels are opposite; in the same sub-pixel row, the grayscale data compensation states of two adjacent sub-pixels are repeated in the opposite but identical order.

[0013] Embodiments of the present invention also provide a driver chip configured to execute program instructions to implement the driving method described above.

[0014] Embodiments of the present invention also provide a display device, including: a display panel; and a driver chip electrically connected to the display panel, configured to execute program instructions to implement the driving method described above.

[0015] In the display panel driving method, driving chip, and display device provided in the embodiments of the present invention, a new design is provided for flipping the polarity of pixels in each pixel column by an even number of sub-pixels in each pixel column, so that in any two adjacent sub-pixel columns, multiple sub-pixels with the same display color and high grayscale data compensation state will not have a polarity that is both positive or negative. This reduces the polarity difference between multiple sub-pixels with the same display color and high grayscale data compensation state in four adjacent sub-pixel columns, thereby improving the phenomenon of perceiving head shaking wrinkles when the human eye perceives the brightness change caused by the polarity change of areas with large polarity differences when the head moves.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" 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 sub-pixels SPX of the displayed image. The non-display area NDA may be an area for providing drive signals to the sub-pixels SPX and some lines such as power lines connecting the drive units. The non-display area NDA may be located on at least one side of the display area DA. The non-display area NDA may at least partially surround the display area DA.

[0026] The display panel 2 includes multiple sub-pixels (SPX), multiple data lines (DT), multiple scan lines (SN), and a gate drive circuit (GDC). The multiple sub-pixels (SPX) are located within the display area (DA). The gate drive circuit (GDC) is located within the non-display area (NDA) and drives multiple rows of sub-pixels (SPX) through the multiple scan lines (SN) to sequentially open multiple rows of sub-pixels (SPX). Simultaneously, the multiple data lines (DT) sequentially load data signals to the multiple rows of sub-pixels (SPX), thereby enabling the display panel 2 to display a complete frame of image within one frame.

[0027] The flip-chip thin 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, multiple sub-pixels SPX are arranged along intersecting row and column directions to form multiple sub-pixel rows SPXR arranged in the column direction, and multiple sub-pixel columns SPXC arranged in the row direction. The multiple sub-pixels SPX include multiple first sub-pixels B, multiple second sub-pixels G, and multiple third sub-pixels R. The multiple sub-pixel rows SPXR include multiple alternating rows of first sub-pixels, multiple rows of second sub-pixels, and multiple rows of third sub-pixels. 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 to this. The multiple sub-pixels SPX within the same sub-pixel row SPXR have the same display color, while the multiple sub-pixels SPX within adjacent sub-pixel rows SPXR have different display colors. That is, the multiple sub-pixels SPX form a Trigate driving architecture.

[0030] Each sub-pixel column SPXC includes multiple sub-pixel groups SPXG, which include sub-pixel group SPXG1 (i.e., the first sub-pixel group), sub-pixel group SPXG2 (i.e., the second sub-pixel group), and sub-pixel group SPXG3 (i.e., the third sub-pixel group). Sub-pixel group SPXG2 is located between sub-pixel groups SPXG1 and SPXG3. Sub-pixel groups SPXG1 and SPXG3 are connected to a corresponding data line DL. Sub-pixel group SPXG2 includes 2n sub-pixels SPX, and sub-pixel group SPXG2 is connected to an adjacent data line DL. n is an integer, for example, n is 0 or a positive integer. That is, this embodiment provides a novel design for flipping pixel polarity by spacing an even number of sub-pixels SPX in each pixel column.

[0031] Based on the above-mentioned new design, within the same frame, among multiple sub-pixels SPX that have the same display color and high grayscale data compensation state H in any two adjacent sub-pixel columns SPXC, at least one sub-pixel SPX has a polarity different from the polarity of the other sub-pixel SPX.

[0032] Thus, this embodiment provides a novel design for flipping pixel polarity in the Trigate driving architecture by spacing an even number of sub-pixels SPX in each pixel column. This ensures that in any two adjacent sub-pixel columns SPXC, multiple sub-pixel SPX with the same display color and high grayscale data compensation state H will not have polarities that are both positive + or negative -. This reduces the polarity difference between multiple sub-pixel SPX with the same display color and high grayscale data compensation state H in four adjacent sub-pixel columns SPXC. This can improve the phenomenon of perceiving head-shaking wrinkles caused by brightness changes in areas with large polarity differences when the head moves.

[0033]

Example 1

[0034] Please see Figure 3 In this embodiment, n is a positive integer, such as 1. That is, in each sub-pixel column SPXC, the pixel polarity is flipped by skipping 2 sub-pixels SPX.

[0035] Each sub-pixel column SPXC includes multiple sub-pixel groups SPXG, and each sub-pixel group SPXG includes 2 (i.e., 2n) sub-pixels SPX. The multiple sub-pixel groups SPXG include sub-pixel group SPXG1 (i.e., the first sub-pixel group), sub-pixel group SPXG2 (i.e., the second sub-pixel group), and sub-pixel group SPXG3 (i.e., the third sub-pixel group), with sub-pixel group SPXG2 located between sub-pixel groups SPXG1 and SPXG3. Each sub-pixel column SPXC is connected between two adjacent data lines DL. A sub-pixel group SPXG is provided between every two sub-pixel groups SPXG connected to one of the data lines DL, and this sub-pixel group SPXG is connected to the other adjacent data line DL. The polarities of the sub-pixels SPXG connected to the same data line DL are the same, while the polarities of the sub-pixel SPXG connected to two adjacent data lines DL are opposite. Thus, this embodiment provides a novel design for flipping pixel polarity by spacing two sub-pixels (SPX) in each pixel column.

[0036] Within the same sub-pixel column SPXC, the grayscale data compensation states of 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, in sequence, low grayscale data compensation state L, high grayscale data compensation state H, and low grayscale data compensation state L. Within the same sub-pixel row SPXR, the grayscale data compensation states of adjacent sub-pixels SPX are repeated in the opposite but identical 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, in sequence, 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] In the same sub-pixel column SPXC, among multiple sub-pixels SPX with the same display color and high grayscale data compensation state H, the polarities of adjacent sub-pixels SPX are opposite. For example, in the first sub-pixel column SPXC, among multiple second sub-pixels G with high grayscale data compensation state H, the polarities of the multiple second sub-pixels G are negative polarity - and positive polarity +, respectively.

[0038] In this way, in any pair of adjacent sub-pixel columns SPXC, there will be no instances where multiple sub-pixels SPX with the same display color and high grayscale data compensation state H have polarities that are all positive + or negative -. This reduces the polarity difference between multiple sub-pixels SPX with the same display color and high grayscale data compensation state H in four adjacent sub-pixel columns SPXC, thereby improving the head-shaking wrinkle phenomenon observed by the human eye due to large regional polarity differences when the head moves. For example, in the multiple second sub-pixels G with high grayscale data compensation state H in the first and second columns of sub-pixel columns SPXC, the polarity of the second sub-pixel G in the first column is negative - and positive +, while the polarity of the second sub-pixel G in the second column is positive + and negative -.

[0039] Furthermore, when sub-pixels SPX with the same display color and high grayscale data compensation state H are illuminated within the same frame to display the same grayscale, the absolute values ​​of the average effective voltages of adjacent data lines DL are the same. For example, when a green sub-pixel with high grayscale data compensation state H is illuminated within 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…, 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…. Therefore, the average effective voltages of the first data line DL and the second data line DL within the same frame are the same in magnitude but opposite in polarity. This effectively reduces the probability of vertical crosstalk.

[0040]

Example 2

[0041] Please see Figure 4 This embodiment is similar to Embodiment 1, except that in this embodiment, n is 2. That is, in each sub-pixel column SPXC, the pixel polarity is flipped by skipping 4 sub-pixels SPX. In other embodiments, n can be 3, 4, 5, ...

[0042] In this way, in any pair of adjacent sub-pixel columns SPXC, there will be no instances where multiple sub-pixels SPX with the same display color and high grayscale data compensation state H have polarities that are all positive + or negative -. This reduces the polarity difference between multiple sub-pixels SPX with the same display color and high grayscale data compensation state H in four adjacent sub-pixel columns SPXC, thereby improving the head-shaking wrinkle phenomenon observed by the human eye due to large regional polarity differences when the head moves. For example, in the multiple second sub-pixels G with high grayscale data compensation state H in the first and second columns of sub-pixel columns SPXC, the polarity of the second sub-pixel G in the first column is negative - and positive +, while the polarity of the second sub-pixel G in the second column is negative + and positive +.

[0043]

Example 3

[0044] Please see Figure 5 In this embodiment, n is 0. Since n = 0, the original second sub-pixel group no longer exists, thus making each sub-pixel column SPXC connected to a corresponding data line DL. The polarities of the sub-pixels SPX of multiple sub-pixel groups SPXG connected to the same data line DL are the same, while the polarities of the sub-pixel SPX of multiple sub-pixel groups SPXG connected to adjacent data lines DL are opposite. Therefore, this embodiment provides a novel design where the polarities of the sub-pixels SPX of the same sub-pixel column SPXC are the same.

[0045] Within 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-pixel SPX in the first 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, in sequence, low grayscale data compensation state L, high grayscale data compensation state H, and low grayscale data compensation state L. Within the same sub-pixel row SPXR, the grayscale data compensation states of two adjacent sub-pixel SPX are repeated in the opposite but identical order. For example, in the first six sub-pixel SPX in the first sub-pixel row SPXR, the grayscale data compensation states of the six sub-pixel SPX are, in sequence, 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 pair of adjacent sub-pixel columns SPXC, there will be no instances where multiple sub-pixels SPX with the same display color and high grayscale data compensation state H have polarities that are both positive + or negative -. This reduces the polarity difference between multiple sub-pixels SPX with the same display color and high grayscale data compensation state H in four adjacent sub-pixel columns SPXC, thereby improving the head-shaking wrinkle phenomenon observed by the human eye due to large regional polarity differences when the head moves. For example, in the multiple second sub-pixels G with high grayscale data compensation state H in the first and second columns of sub-pixel columns SPXC, the polarity of the second sub-pixel G in the first column is negative - or negative -, while the polarity of the second sub-pixel G in the second column is positive + or positive +.

[0047] Furthermore, when sub-pixels SPX with the same display color and high grayscale data compensation state H are illuminated within the same frame to display the same grayscale, the absolute values ​​of the average effective voltages of adjacent data lines DL are the same. For example, when a green sub-pixel with high grayscale data compensation state H is illuminated within 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…, 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…. Therefore, the average effective voltages of the first data line DL and the second data line DL within the same frame are the same in magnitude but opposite in polarity. This effectively reduces the probability of vertical crosstalk.

[0048]

Example 4

[0049] Please see Figure 6 Embodiments of the present invention also provide a driving method for a display panel, applied in the display module 1 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, drive multiple sub-pixels SPX to be displayed within multiple frames.

[0051] Each of the sub-pixels SPX has a high grayscale data compensation state H and a low grayscale data compensation state L in the multi-frames, and has a positive polarity + and a negative polarity -.

[0052] Each sub-pixel column SPXC includes multiple sub-pixel groups SPXG. Between every two sub-pixel groups SPXG connected to the corresponding data line DL, there are 2n sub-pixels SPX. These 2n sub-pixels SPX are connected to another adjacent data line DL, where n is an integer. That is, this embodiment provides a novel design for flipping pixel polarity by spacing an even number of sub-pixels SPX in each pixel column.

[0053] Based on the above-mentioned new design, within the same frame, among multiple sub-pixels SPX that have the same display color and high grayscale data compensation state H in any two adjacent sub-pixel columns SPXC, at least one sub-pixel SPX has a polarity different from the polarity of the other sub-pixel SPX.

[0054] In this way, in any two adjacent sub-pixel columns SPXC, there will be no phenomenon where multiple sub-pixels SPX with the same display color and high grayscale data compensation state H have the same polarity as positive + or negative -. This reduces the polarity difference between multiple sub-pixels SPX with the same display color and high grayscale data compensation state H in four adjacent sub-pixel columns SPXC, thereby improving the head-shaking wrinkle phenomenon observed by the human eye when the head moves due to large regional polarity differences.

[0055] Furthermore, every p frames, the polarity of multiple sub-pixels SPX of multiple sub-pixel groups PXG is reversed, where p is a positive integer, such as 1, 2, 3. In this way, polarity symmetry in the time dimension can be achieved.

[0056]

Example 5

[0057] Embodiments of the present invention also provide a driver chip configured to execute program instructions to implement the driving method described above. Specifically, the driver chip may be a source driver chip or a timing control chip.

[0058] Thus, within the same frame, among a plurality of sub-pixels SPX that have the same display color and high grayscale data compensation state H in any two adjacent sub-pixel columns SPXC, at least one sub-pixel SPX has a polarity different from the polarity of the other sub-pixel SPX.

[0059] In this way, in any two adjacent sub-pixel columns SPXC, there will be no phenomenon where multiple sub-pixels SPX with the same display color and high grayscale data compensation state H have the same polarity as positive + or negative -. This reduces the polarity difference between multiple sub-pixels SPX with the same display color and high grayscale data compensation state H in four adjacent sub-pixel columns SPXC, thereby improving the head-shaking wrinkle phenomenon observed by the human eye when the head moves due to large regional polarity differences.
