[0003] Triple-rate-driving (TRD) driving technology connects three horizontally adjacent sub-pixels of different colors to a single data line, which are driven sequentially by different scan lines. This reduces the number of data lines and data driver output channels by one-third compared to conventional methods. This means that a single source driver chip can perform the work of three, greatly simplifying the manufacturing process and effectively reducing manufacturing costs. Technical issues

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. The features specified as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0031] Please refer to Figure 1. This embodiment provides a display panel, which includes multiple pixels, each pixel includes first to i-th sub-pixels of i different colors; the first to i-th sub-pixels in a pixel are commonly connected to a data line and are respectively connected to the first to i-th gate lines, where i is a positive integer greater than 1.

[0032] Specifically, the structure of the display panel is described using i=3 as an example. Accordingly, each pixel includes a first subpixel, a second subpixel, and a third subpixel of three different colors. For example, the first subpixel is a red subpixel R, the second subpixel is a green subpixel G, and the third subpixel is a blue subpixel B. The data lines and gate lines in the display panel are arranged crosswise, the subpixels of the three colors are alternately and repeatedly arranged in the vertical direction, and the subpixels of the same color are repeatedly arranged in the horizontal direction.

[0033] In Figure 1, the R, G, and B sub-pixels in each vertically arranged pixel are connected to the data line D1 or D2 in common, and are connected to three gate lines G1-G3 or G4-G6 respectively. Each row of sub-pixels shares a gate line, and is thus driven sequentially within each frame display cycle. Therefore, the display panel includes m data lines for driving 3m horizontally arranged sub-pixels and 3n gate lines for driving n vertically arranged sub-pixels, thereby achieving a resolution of m×n pixels (m and n are natural numbers). Therefore, compared with the conventional structure, the number of gate lines has increased three times, but the number of data lines has been reduced to one-third, so one data line is needed to charge the sub-pixels of three colors.

[0034] Based on the above display panel, referring to FIG. 2 , the present application provides a method for driving a display panel, the method comprising:

[0035] 100. Obtain a display scene of a video source signal;

[0036] 200. When the display scene of the video source signal is the target display scene, the first to i-th sub-pixels are controlled to be charged alternately in sequence, and sub-pixels of one color are charged in each frame display period of the video source signal.

[0037] Among them, the display scene of the video source signal refers to the refresh rate requirement of the picture display of the video source signal, and the target display scene refers to the picture display of the video source signal with a lower refresh rate requirement, such as a static picture or a soothing dynamic picture. In this application, by obtaining the display scene of the video source signal, when the picture display of the video source signal has a low refresh rate requirement, the first to i-th sub-pixels are controlled to be charged alternately in sequence, and only sub-pixels of one color are charged in each frame display cycle. For example, as shown in Figure 3, only the red sub-pixel is controlled to be charged in the 3n+1 frame, then only the green sub-pixel is controlled to be charged in the 3n+2 frame, and only the blue sub-pixel is controlled to be charged in the 3n+3 frame. That is, in each frame display cycle, one data line is only used to charge sub-pixels of one color. Compared with one data line charging sub-pixels of three colors in each frame display cycle, the charging time of the sub-pixels can be increased, thereby effectively alleviating the problem of uneven brightness of the display panel caused by insufficient sub-pixel charging.

[0038] Referring to FIG. 4 , in some embodiments, step 200 specifically includes:

[0039] 210. Acquire a frame rate of a video source signal, and reduce the frame rate of the video source signal to a target frame rate;

[0040] 220. Control the first to i-th sub-pixels to be charged alternately in sequence according to the target frame rate, and charge sub-pixels of one color in each frame display period of the video source signal.

[0041] The frame rate of the video source signal in this application is the actual frame rate of the video source signal. In this embodiment, the actual frame rate of the video source signal is used as the initial frame rate. The frame rate in this application matches the refresh rate of the display panel, that is, when the frame rate is high, the corresponding refresh rate is also high; when the frame rate is low, the corresponding refresh rate of the display panel is also high. If the image display of the video source signal has a low refresh rate requirement, the initial frame rate can be appropriately reduced to the target frame rate, thereby increasing the scanning time of each frame and correspondingly increasing the charging time of each row of sub-pixels.

[0042] Referring to FIG. 5 , in some embodiments, the method for driving a display panel further includes: 300. When the display scene of the video source signal is a non-target display scene, controlling the first to i-th sub-pixels to be alternately charged in sequence within a one-frame display period of the video source signal. Specifically, when the display scene of the video source signal is a non-target display scene, i.e., the image display of the video source signal requires a high refresh rate, controlling the plurality of sub-pixels to be alternately charged in sequence within a one-frame display period of the video source signal to facilitate image display of the video source signal.

[0043] Referring to FIG. 6 , as an embodiment, step 300 specifically includes:

[0044] 310. Acquire a frame rate of a video source signal, and use the frame rate of the video source signal as an initial frame rate;

[0045] 320. Control the first to i-th sub-pixels to be charged alternately in sequence within a frame display period of the video source signal according to the initial frame rate.

[0046] In this embodiment, when the screen display of the video source signal has a high requirement for the refresh rate, the frame rate of the video source is directly obtained. According to the initial frame rate of the video source, the first to i-th sub-pixels are controlled to be charged alternately in sequence within a frame display period of the video source signal, so as to realize the screen display of the video source signal.

[0047] As an embodiment, the initial frame rate in the present application can be i times the target frame rate; if each pixel includes sub-pixels of three colors, that is, i=3, the initial frame rate can be i times the target frame rate, that is, the target frame rate is 1 / 3 of the initial frame rate. Then, when only sub-pixels of one color are charged in one frame display period, it is equivalent to using all the charging time of the other two colors in one frame display period to charge the sub-pixels of one color. Then, for the entire row of sub-pixels, the time used by one gate line to charge the sub-pixels in that row becomes three times the original time, and the frame rate will be reduced to 1 / 3 of the initial frame rate; conversely, if all sub-pixels of one color are charged in one frame display period, the frame rate of the video source signal needs to be reduced to 1 / 3 of the initial frame rate to obtain the target frame rate.

[0048] Referring to FIG. 7 , an embodiment of the present application further provides a method for driving a display panel, the method comprising:

[0049] 101. Acquire a frame rate of a video source signal and a display scene, and use the acquired frame rate of the video source signal as an initial frame rate;

[0050] 102. When the display scene of the video source signal is the target display scene, reduce the initial frame rate to a first frame rate, and control the first to i-th sub-pixels to be alternately charged in sequence according to the first frame rate, and charge sub-pixels of one color in each frame display period of the video source signal, so that the display panel displays an image corresponding to the video source signal;

[0051] 103. When the smoothness of the image displayed on the display panel according to the first frame rate reaches the target smoothness, the first frame rate is stored as the target frame rate according to the external control instruction.

[0052] In this embodiment, during the display panel testing phase, the frame rate and display scene of the video source signal to be tested are obtained. If the refresh rate required for the image display of the video source signal is low, the frame rate of the video source signal is reduced to a first frame rate. The first through i-th sub-pixels are controlled to alternately charge in accordance with the first frame rate, and sub-pixels of a single color are charged during each frame display period of the video source signal, so that the display panel displays the image corresponding to the video source signal. The smoothness of the image displayed by the display panel according to the first frame rate control is then observed to determine whether it reaches a target smoothness. The target smoothness is defined as a smoothness that does not affect human perception, i.e., the image appears smooth to the human eye, i.e., the image smoothness reaches the target smoothness. If the image displayed by the display panel according to the first frame rate control reaches the target smoothness, an external control instruction is obtained. According to the external control instruction, the first frame rate is stored as the target frame rate, so that the target frame rate can be directly called to control the display of the display panel.

[0053] Referring to FIG. 8 , in some embodiments, the method for driving a display panel further includes:

[0054] 104. When the smoothness of the image displayed on the display panel according to the first frame rate control does not reach the target smoothness, the initial frame rate is reduced to a second frame rate, and the first to i-th sub-pixels are controlled to be alternately charged in sequence according to the second frame rate, and sub-pixels of one color are charged in each frame display period of the video source signal, so that the display panel displays an image corresponding to the video source signal, wherein the second frame rate is different from the first frame rate;

[0055] 105. When the smoothness of the image displayed on the display panel according to the second frame rate is controlled to reach the target smoothness, the second frame rate is stored as the target frame rate according to the external control instruction.

[0056] In this embodiment, when the image smoothness of the display panel does not reach the target smoothness according to the first frame rate control, the initial frame rate is reduced to a second frame rate, which is different from the first frame rate. If the image display effect is poor when the initial frame rate is reduced to the first frame rate, the initial frame rate is further adjusted to the second frame rate. If the image displayed by the display panel reaches the target smoothness according to the second frame rate control, an external control instruction is obtained, and the second frame rate is stored as the target frame rate according to the external control instruction, so that the target frame rate can be directly called to control the display of the display panel later. Otherwise, the initial frame rate will continue to be adjusted for display testing to obtain more target frame rates for storage.

[0057] Referring to FIG. 9 , in some embodiments, the method for driving a display panel further includes:

[0058] 106. Obtain the number of stored target frame rates;

[0059] 107. When the number of target frame rates is less than the preset number, the frame rate of the video source signal and the display scene are acquired again, and the acquired frame rate of the video source signal is used as the initial frame rate;

[0060] 108. When the display scene of the video source signal is the target display scene, reduce the initial frame rate to a first frame rate, and control the first to i-th sub-pixels to be alternately charged in sequence according to the first frame rate, and charge sub-pixels of one color in each frame display period of the video source signal, so that the display panel displays an image corresponding to the video source signal;

[0061] 109. When the smoothness of the image displayed on the display panel according to the first frame rate control reaches the target smoothness, the first frame rate is stored as the target frame rate according to the external control instruction.

[0062] In this application, the number of stored target frame rates is also obtained. When the number of stored target frame rates reaches a preset number, the test is stopped. If the target frame rate is less than the preset number, the video source signal is continued to be added, the frame rate and display scene of the video source signal are obtained, and a display test is performed. When the display scene of the video source signal is the target display scene, the initial frame rate is reduced to a first frame rate, and the first to i-th sub-pixels are controlled to be charged alternately in sequence according to the first frame rate, and sub-pixels of one color are charged in each frame display cycle of the video source signal so that the display panel displays the image corresponding to the video source signal. When the smoothness of the picture displayed by the display panel according to the first frame rate control reaches the target smoothness, the first frame rate is stored as the target frame rate according to the external control instruction. Equivalently, when the target frame rate is less than the preset number, steps 101 to 105 are repeated to obtain more target frame rates.

[0063] The display panel driving method of this embodiment is applied during a test phase of the display panel. During the test phase, the frame rate of a video source signal is adjusted to observe the smoothness of the display panel's image at a first frame rate or a second frame rate. Based on the smoothness of the image, a determination is made as to whether to store the first frame rate or the second frame rate as a target frame rate. Multiple target frame rates are thus obtained and stored in advance. Furthermore, if the number of target frame rates is insufficient, additional video source signals are added to continue testing, so that a sufficient number of target frame rates can be stored in advance.

[0064] An embodiment of the present application further provides a driving device for a display panel, which includes a driving module, and the driving module is used to drive the display panel to display a corresponding picture; since the display panel structure is described in detail above, it will not be repeated here.

[0065] The driving module in the present application is respectively connected to the data lines and the gate lines of the display panel. The driving module is used to control the first to i-th sub-pixels to be charged alternately in sequence through the data lines and the gate lines when the display scene of the video source signal is the target display scene, and to charge the sub-pixels of one color within each frame display cycle of the video source signal, thereby increasing the charging time of the sub-pixels and effectively alleviating the problem of uneven brightness of the display panel caused by insufficient charging of the sub-pixels.

[0066] In some embodiments, the driving module includes a controller, a gate driving unit, and a source driving unit, wherein the gate driving unit is connected to multiple gate lines and the controller, and the source driving unit is connected to multiple data lines and the controller. The controller is used to obtain a display scene of a video source signal, and when the display scene of the video source signal is a target display scene, the frame rate of the video source signal is reduced to a target frame rate, and a first gate control signal and a first source control signal and a data signal corresponding to the video source signal are output according to the target frame rate; the gate driving unit is used to control the first to i-th sub-pixels to be alternately turned on in sequence through the first to i-th gate lines according to the first gate control signal, and only one color sub-pixel is turned on in each frame display period; the source driving unit is used to charge the corresponding sub-pixel according to the source control signal and the data voltage corresponding to the data signal when any sub-pixel among the first to i-th sub-pixels is turned on.

[0067] In some embodiments, the controller is also used to use the frame rate of the video source signal as the initial frame rate when the display scene of the video source signal is a non-target display scene, and output a second gate control signal and a second source control signal and a data signal corresponding to the video source signal according to the initial frame rate; the gate driving unit is also used to control the first to i-th sub-pixels to be alternately turned on in sequence within a frame display period of the video source signal through the first to i-th gate lines according to the first gate control signal; the source driving unit is also used to charge the corresponding sub-pixel with the data voltage corresponding to the data signal according to the second source control signal when any sub-pixel among the first to i-th sub-pixels is turned on.

[0068] The driving module in the present application obtains the display scene of the video source signal. When the screen display of the video source signal has a low refresh rate requirement, it controls the first to i-th sub-pixels to be charged alternately in sequence, and only charges sub-pixels of one color in each frame display cycle. Compared with one data line charging sub-pixels of multiple colors in each frame display cycle, this can increase the charging time of the sub-pixels, thereby effectively alleviating the problem of uneven brightness of the display panel caused by insufficient charging of sub-pixels.

[0069] Referring to FIG. 10 , an embodiment of the present application further provides a display device, which includes a driving module 10 and the above-mentioned display panel 20 . Since the structure of the display panel 20 has been described in detail above, it will not be repeated here.

[0070] The driving module 10 in the present application is respectively connected to the data lines and gate lines of the display panel 20. The driving module 10 is used to control the first to i-th sub-pixels to be charged alternately in sequence through the data lines and gate lines when the display scene of the video source signal is the target display scene, and to charge the sub-pixels of one color in each frame display cycle of the video source signal, thereby increasing the charging time of the sub-pixels and effectively alleviating the problem of uneven brightness of the display panel 20 caused by insufficient charging of the sub-pixels.

[0071] In some embodiments, the driving module 10 includes a controller 111, a gate driving unit 112, and a source driving unit 113, wherein the gate driving unit 112 is connected to multiple gate lines and the controller 111, and the source driving unit 113 is connected to multiple data lines and the controller 111. The controller 111 is used to obtain a display scene of a video source signal. When the display scene of the video source signal is a target display scene, the frame rate of the video source signal is reduced to a target frame rate, and a first gate control signal and a first source control signal and a data signal corresponding to the video source signal are output according to the target frame rate; the gate driving unit 112 is used to control the first to i-th sub-pixels to be alternately turned on in sequence through the first to i-th gate lines according to the first gate control signal, and only turn on sub-pixels of one color in each frame display period; the source driving unit 113 is used to charge the corresponding sub-pixel according to the source control signal and the data voltage corresponding to the data signal when any sub-pixel among the first to i-th sub-pixels is turned on.

[0072] In some embodiments, the controller 111 is also used to use the frame rate of the video source signal as the initial frame rate when the display scene of the video source signal is a non-target display scene, and output a second gate control signal and a second source control signal and a data signal corresponding to the video source signal according to the initial frame rate; the gate driving unit 112 is also used to control the first to i-th sub-pixels to be alternately turned on in sequence within a frame display period of the video source signal through the first to i-th gate lines according to the first gate control signal; the source driving unit 113 is also used to charge the corresponding sub-pixel with the data voltage corresponding to the data signal according to the second source control signal when any sub-pixel among the first to i-th sub-pixels is turned on.

[0073] The driving module 10 in the present application obtains the display scene of the video source signal. When the screen display of the video source signal has a low refresh rate requirement, it controls the first to i-th sub-pixels to be charged alternately in sequence, and only charges sub-pixels of one color in each frame display cycle. Compared with one data line charging sub-pixels of multiple colors in each frame display cycle, it can increase the charging time of the sub-pixels, thereby effectively alleviating the problem of uneven brightness of the display panel 20 caused by insufficient charging of sub-pixels.
