[0002] Display panels typically consist of an array of subpixels, including red subpixels (R), green subpixels (G), and blue subpixels (B). Each subpixel is electrically connected to a scan line and a data line. In a tri-gate display panel, the number of data lines is one-third that of a normal driving architecture, and the number of scan lines is three times that of a normal driving architecture. The red subpixels (R), green subpixels (G), and blue subpixels (B) in each column of subpixels are arranged alternately in a preset order, and each row of subpixels consists of the same color. Tri-gate display panels typically use a line-by-line scanning sequence; however, due to the time difference in the sequential opening of subpixels, color trailing can easily occur in dynamic scenes, affecting the display quality.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0046] In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0047] Please see Figure 1 , Figure 1This illustration shows an example structure of a display device according to an embodiment of this application. The display device includes a display panel 10, a processor 20, and a source driver chip 30. The processor 20 is used to acquire input signals from a signal source, process the input signals for data and timing, and generate driving signals. The source driver chip 30 is used to drive the display panel 10 to display an image based on the driving signals. In some examples, the processor 20 can be a timing controller or a SOC (System-on-a-Chip) chassis.

[0048] Please see Figure 2 , Figure 2 This illustration shows an example structure of a display panel according to an embodiment of this application. The display panel 10 typically includes an array of multiple sub-pixels, each sub-pixel electrically connected to a scan line and a data line. Taking a Tri-Gate architecture display panel 10 as an example, the multiple sub-pixels may include a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. Each row of sub-pixels consists of sub-pixels of the same color, and each column of sub-pixels is arranged alternately and repeatedly in a preset order. For example, the first color sub-pixel may be a blue sub-pixel B, the second color sub-pixel may be a green sub-pixel G, and the third color sub-pixel may be a red sub-pixel R. For ease of description, unless otherwise specified in the following embodiments, the first color is always blue, the second color is always green, and the third color is always red.

[0049] In this embodiment, the display panel 10 may include multiple circular regions 11. Each circular region 11 includes at least one set of sub-pixels. Each set of sub-pixels includes three rows of first-color sub-pixels, second-color sub-pixels, and third-color sub-pixels arranged in a preset order. For example, if each circular region 11 includes one set of sub-pixels arranged in the order of blue, green, and red, the set of sub-pixels in the first circular region 11 can be represented as B1, G1, R1; the set of sub-pixels in the second circular region 11 can be represented as B2, G2, R2; the set of sub-pixels in the third circular region 11 can be represented as B3, G3, R3, and so on. It is understood that the number of sub-pixel rows in each circular region 11 is the same. Each circular region 11 may include one set of sub-pixels, or it may include two or more sets of sub-pixels.

[0050] Typically, the Tri-Gate architecture display panel 10 is driven using progressive scan timing. Taking a display frequency of 60Hz as an example, the duration of one frame is 1 / 60 = 16.7ms, meaning that it takes 16.7ms to complete the driving and display of one frame. However, due to the time difference in the sequential opening of subpixels, color trailing is prone to occur in dynamic scenes, affecting the display effect.

[0051] Please refer to the following: Figures 3a to 3c , Figure 3a This diagram illustrates the data splitting process for interlaced scanning frequency doubling. Figure 3b This diagram illustrates the GOA timing for interlaced scanning frequency multiplication. Figure 3c The diagram illustrates the display effect of interlaced scanning frequency doubling. For example, the input signal obtained from the signal source is 4K2K@60Hz, that is, the resolution is 3840×2160 and the display frequency is 60Hz. The SOC chassis board multiplies the input signal to 4K1K@120Hz through interlaced scanning, that is, the resolution is 3840×1080 and the display frequency is 120Hz. In other words, the original 1 frame of 4K2K data (a) is split into 2 frames of data, namely 4K1K data a1 composed of odd-numbered rows of data and 4K1K data a2 composed of even-numbered rows of data. The synchronously configured GOA (Gate Driver on Array) timing is as follows: in the first frame, each sub-pixel of the odd-numbered rows is opened sequentially, as shown in CK1, 3, 5, and 7; in the second frame, each sub-pixel of the even-numbered rows is opened sequentially, as shown in CK2, 4, 6, and 8. The data is output to the source driver chip 30, and finally, the display panel 10 overlays and displays a 4K 1K@120Hz image. Here, STV is the frame start signal, H represents the row, 1H represents the row scan duration, and Blanking time represents the blanking time. Based on... Figure 2 The display panel 10 shown is illustrated using a 6-row sub-pixel arrangement of B, G, R, B, G, R as an example. After frequency doubling processing via interlaced scanning, there are two frames of frequency doubling signals. The first frame (0ms to 8.3ms) of the frequency doubling signal sequentially drives the first, third, and fifth row sub-pixels B1, R1, and G2 for display. The second frame (8.3ms to 16.7ms) of the frequency doubling signal sequentially drives the second, fourth, and sixth row sub-pixels G1, B2, and R2 for display, and so on. The third frame (16.7ms to 25ms) of the frequency doubling signal sequentially drives the first, third, and fifth row sub-pixels B1, R1, and G2 for display. The fourth frame (25ms to 33.3ms) of the frequency doubling signal sequentially drives the second, fourth, and sixth row sub-pixels G1, B2, and R2 for display.

[0052] However, research and experiments have revealed that when using the interlaced scanning frequency multiplication method on a Tri-Gate architecture display panel, dynamic trailing still occurs when displaying dynamic images, and the display effect remains unsatisfactory.

[0053] In view of this, the present application provides a driving method for a display panel, which, by using the principle of spatial jitter on the basis of frequency doubling timing, disrupts the color display order of the loop area, thereby reducing the visual misalignment perceived by the human eye, and thus improving the color trailing phenomenon in dynamic image display, enhancing the display effect, and thus solving at least part of the above-mentioned technical problems.

[0054] Please see Figure 4 , Figure 4 The overall flow of the display panel driving method according to an embodiment of this application is illustrated. The display panel driving method includes the following steps:

[0055] Step 401: Perform frequency multiplication on the current frame input signal to obtain the first driving signal. Under the first driving signal, the color display order of each loop region is the same, wherein the color display order is the opening order of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel.

[0056] In some embodiments, the current frame input signal has a first display frequency N1, and the first driving signal has a second display frequency N2, satisfying: N2 = N1 × 3 × n, where n is a positive integer. For example, n can take the values ​​1, 2, 3, ... Taking N1 = 60Hz as an example, when n = 1, N2 = 3N1 = 180Hz; when n = 2, N2 = 6N1 = 360Hz, and so on. Further details are omitted here.

[0057] In some embodiments, step 401 can be implemented through the following steps:

[0058] Step 1: Using a scanning method with an interval of 3n-1 rows, the current frame input signal is split into 3n frame frequency multiplication signals that drive the corresponding row of sub-pixels for display.

[0059] For example, when n=1, the scanning method with an interval of 3n-1 rows is also the scanning method with an interval of 2 rows. Specifically, the 1st row, the 4th row, the 7th row, etc. are scanned in sequence. After the scan is completed, the 2nd row, the 5th row, the 8th row, etc. are scanned in sequence. After the scan is completed, the 3rd row, the 6th row, the 9th row, etc. are scanned in sequence, and so on.

[0060] It is understandable that when n=2, the scanning method with an interval of 3n-1 rows is also the scanning method with an interval of 5 rows. Specifically, the 1st row, the 7th row, the 13th row, and so on are scanned in sequence. After the scan is completed, the 2nd row, the 8th row, the 14th row, and so on are scanned in sequence. After the scan is completed, the 3rd row, the 9th row, the 15th row, and so on are scanned in sequence, and so on in a loop.

[0061] Step 2: Determine the 3n-frame frequency multiplication signal as the first driving signal.

[0062] Specifically, the sum of the frame durations of the 3n-frame frequency multiplication signals is equal to the frame duration of the current frame input signal.

[0063] For example, when n=1, the frequency-doubled signal has a total of 3 frames, and when n=2, the frequency-doubled signal has a total of 6 frames.

[0064] Please see Figure 5 , Figure 5 This diagram illustrates the display effect of the first driving signal in an embodiment of this application. Based on Figure 2 The display panel 10 shown, with a first display frequency N1 = 60Hz, and sub-pixels arranged alternately in the order of B, G, R, and n = 1, is split into 3 frames of frequency multiplication signals. The first frame (0ms to 5.57ms) of the frequency multiplication signal drives the first, fourth, and seventh rows of sub-pixels B1, B2, and B3 to be displayed sequentially. The second frame (5.57ms to 11.1ms) of the frequency multiplication signal drives the second, fifth, and eighth rows of sub-pixels G1, G2, and G3 to be displayed sequentially. The third frame (11.1ms to 16.7ms) of the frequency multiplication signal drives the third, sixth, and ninth rows of sub-pixels R1, R2, and R3 to be displayed sequentially. Finally, the display panel 10 displays a 180Hz image.

[0065] It is understandable that each frequency multiplication signal drives a sub-pixel of the same color.

[0066] By using the above frequency multiplication method, the RGB three-row sub-pixels can be fully opened frame by frame within the frame duration of the current frame input signal, which facilitates subsequent timing adjustments.

[0067] In some examples, each loop region may consist of only one set of sub-pixels, and under the first driving signal, the color display order of each loop region is configured to display the first color, the second color, and the third color in sequence.

[0068] In this way, each loop region is the smallest loop unit, which allows for a finer granularity to adjust the visual misalignment perceived by the human eye, thus achieving a better subjective effect.

[0069] Step 402: Based on the first driving signal, generate a second driving signal. Under the second driving signal, the color display order of each loop area is different from the color display order of the adjacent previous loop area.

[0070] In some embodiments, step 402 can be implemented by the following steps:

[0071] Step 1: Generate multiple first candidate sequences based on the permutations and combinations of the first, second, and third colors.

[0072] In some examples, the first alternative order has a total of C. 1 3×C 1 2×C 11 = 6 possibilities. For example, multiple first alternative sequences are configured to display the first color, second color, and third color in sequence; the first color, third color, and second color in sequence; the second color, first color, and third color in sequence; the second color, third color, and first color in sequence; the third color, first color, and second color in sequence; and the third color, second color, and first color in sequence. For instance, the 6 first alternative sequences are RGB, RBG, GBR, GRB, BGR, and BRG.

[0073] It is understandable that if the loop region includes two or more groups of sub-pixels, then there will be more permutations and combinations of the first color, the second color, and the third color, and there will also be more first alternative orders. For example, when the loop region includes two groups of sub-pixels, there can be 36 first alternative orders. The specific order can be implemented according to the actual situation and needs. This application embodiment does not limit this.

[0074] Step 2: For each loop region, based on the color display order of the adjacent previous loop region, determine the color display order of the corresponding loop region from multiple first alternative orders.

[0075] In some examples, step two can be achieved through the following steps:

[0076] The first step is to determine a second alternative order from multiple first alternative orders that differs from the color display order of the adjacent previous cycle area.

[0077] The second step is to determine any one of the multiple second alternative orders as the color display order for the corresponding loop area.

[0078] By using the above method, the opening order of the three-color sub-pixels can be disrupted to avoid the drawback that the human eye can easily perceive the obvious regularity when using the first driving signal. After the order is disrupted, the minimum cycle unit can be increased in a spatial superposition manner, so that the visual misalignment perceived by the human eye can be superimposed and weakened.

[0079] In some examples, the color display order of any six adjacent cyclic regions can be different. Step two can then be implemented through the following steps:

[0080] From a plurality of first alternative sequences, a second alternative sequence is determined that is different from the color display sequence of the five consecutive adjacent loop regions, and this second alternative sequence is determined as the color display sequence of the loop region.

[0081] By setting the color display order of any six adjacent cyclic areas to be different in the above manner, the opening order of the three-color sub-pixels can be disrupted to the greatest extent. This allows for better utilization of the spatial dithering principle, which can reduce the visual misalignment perceived by the human eye, thereby improving the color trailing phenomenon in dynamic image display and enhancing the display effect.

[0082] Step 3: Based on the color display order of each loop region, adjust the sub-pixels corresponding to the frequency multiplication signal of each frame to obtain the frequency multiplication signal updated after 3n frames.

[0083] For example, the sub-pixels corresponding to the three frames of frequency multiplication signals are blue sub-pixel B, green sub-pixel G, and red sub-pixel R, respectively. Each frequency multiplication signal corresponds to a solid color image, and the original color display order of each loop region is also BGR. If the color display order of the second loop region is GBR, then the fourth row sub-pixel B originally driven by the first frame frequency multiplication signal is adjusted to drive the fifth row sub-pixel G, the fifth row sub-pixel G originally driven by the second frame frequency multiplication signal is adjusted to drive the fourth row sub-pixel B, and the third frame frequency multiplication signal remains unchanged, thus obtaining three updated frequency multiplication signals, each corresponding to a mixed color image.

[0084] Step four: Determine the frequency multiplication signal updated after 3n frames as the second driving signal.

[0085] Please see Figure 6 , Figure 6 This diagram illustrates the display effect of the second driving signal in an embodiment of this application. Based on Figure 2 The display panel 10 shown, with a first display frequency N1 = 60Hz, and sub-pixels arranged alternately in the order of B, G, R, and n = 1, if the color display order of any six adjacent cyclic areas 11 is different, and from top to bottom they are BGR, GBR, GRB, RGB, RBG, BRG, then the second driving signal includes a frequency multiplier signal updated for 3 frames. The frequency multiplier signal updated in the first frame (0ms~5.57ms) sequentially drives the first, fifth, eighth, twelfth, fifteenth, and sixteenth rows of sub-pixels B1, G2, G3, R4, R5, and B6 are displayed. The frequency multiplication signal updated in the second frame (5.57ms~11.1ms) sequentially drives the sub-pixels G1, B2, R3, G4, B5, and R6 in the second, fourth, ninth, eleventh, thirteenth, and eighteenth rows to be displayed. The frequency multiplication signal updated in the third frame (11.1ms~16.7ms) sequentially drives the sub-pixels R1, R2, B3, B4, G5, and G6 in the third, sixth, seventh, tenth, fourteenth, and seventeenth rows to be displayed. Finally, the display panel 10 overlays and displays a 180Hz image.

[0086] Step 403: Based on the second driving signal, drive the display panel to display the current frame.

[0087] It is understood that the method in this application embodiment can utilize the principle of spatial jitter on the basis of frequency doubling timing to disrupt the color display order of the loop area, thereby reducing the visual misalignment perceived by the human eye, thus improving the color trailing phenomenon in dynamic image display and enhancing the display effect.

[0088] Accordingly, please refer to Figure 7 , Figure 7 This diagram illustrates the structure of a driving device for a display panel according to an embodiment of this application. The driving device for the display panel provided in this embodiment can be disposed in the processor 20, and specifically includes a frequency multiplier module 201, an adjustment module 202, and a driving module 203.

[0089] The frequency multiplication module 201 is used to perform frequency multiplication processing on the current frame input signal to obtain the first driving signal. Under the first driving signal, the color display order of each loop area is the same, and the color display order is the opening order of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel.

[0090] The adjustment module 202 is used to generate a second driving signal based on the first driving signal. Under the second driving signal, the color display order of each loop area is different from the color display order of the adjacent previous loop area.

[0091] The driving module 203 is used to drive the display panel to display the current frame based on the second driving signal.

[0092] In some embodiments, the current frame input signal has a first display frequency N1, and the first drive signal has a second display frequency N2, satisfying: N2 = N1 × 3 × n, where n is a positive integer.

[0093] In some embodiments, the frequency multiplier module 201 is specifically used for:

[0094] The current frame input signal is divided into 3n frames of frequency multiplication signals driven sequentially by scanning at 3n-1 line intervals. Each frame of frequency multiplication signal is used to drive the corresponding row of sub-pixels for display.

[0095] The 3n-frame frequency multiplication signal is determined as the first driving signal.

[0096] In some embodiments, n = 1; each loop region includes a set of sub-pixels, and under the first driving signal, the color display order of each loop region is configured to display the first color, the second color, and the third color in sequence.

[0097] In some embodiments, the adjustment module 202 is specifically used for:

[0098] Based on the permutations and combinations of the first, second, and third colors, multiple first candidate sequences are generated;

[0099] For each loop region, the color display order of the corresponding loop region is determined from multiple first alternative orders based on the color display order of the adjacent previous loop region;

[0100] Based on the color display order of each loop region, the sub-pixels corresponding to the frequency multiplication signal of each frame are adjusted to obtain the frequency multiplication signal updated after 3n frames;

[0101] The frequency-doubled signal updated after 3n frames is determined as the second driving signal.

[0102] In some embodiments, the adjustment module 202 is specifically used for:

[0103] From a plurality of first alternative sequences, determine a second alternative sequence that differs from the color display sequence of the adjacent previous cycle region;

[0104] Choose any one of the multiple second alternative orders as the color display order for the corresponding loop area.

[0105] In some embodiments, multiple first alternative sequences are configured to display a first color, a second color, and a third color in sequence; display a first color, a third color, and a second color in sequence; display a second color, a first color, and a third color in sequence; display a second color, a third color, and a first color in sequence; display a third color, a first color, and a second color in sequence; and display a third color, a second color, and a first color in sequence.
