Description

[0001] This present application claims priority of the Chinese patent application with the Chinese Patent Application No. 202311461185.1, filed in the China National Intellectual Property Administration on November 3, 2023, and entitled "DRIVING METHOD FOR DISPLAY PANEL AND DISPLAY APPARATUS", which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0003] Triple-rate-driving (TRD) technology refers to a technology in which three horizontally adjacent sub-pixels of different colors are connected to a single data line and sequentially driven by different gate lines. Therefore, the number of data lines and the number of output channels of a data driver can be reduced to one third compared to those in a conventional configuration. That is, one source driver chip can perform the work of three source driver chips, which greatly simplifies the manufacturing process and effectively reduces manufacturing costs.TECHNICAL PROBLEMS

[0004] However, in this type of method, because the number of driver chips is reduced, the configuration changes from one source driver chip driving one data line to one source driver chip driving multiple data lines. The time allocated to each data line is thus reduced to one third of the original time. This leads to insufficient charging of storage capacitors and insufficient liquid crystal deflection, which in turn affects the light transmittance of pixels, thereby causing uneven picture brightness.TECHNICAL SOLUTIONS

[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are merely a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0015] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined by "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality of" means two or more, unless otherwise explicitly and specifically defined.

[0016] Referring to FIG. 1, this embodiment provides a display panel. The display panel includes a plurality of pixels, and each of the plurality of pixels includes first to i-th sub-pixels of i different colors. The first to i-th sub-pixels in each of the plurality of pixels are commonly connected to a data line and are respectively connected to first to i-th gate lines, where i is a positive integer greater than 1.

[0017] Specifically, a structure of the display panel is described by taking i=3 as an example. Correspondingly, each of the plurality of pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel of three different colors. For example, the first sub-pixel is a red sub-pixel R, the second sub-pixel is a green sub-pixel G, and the third sub-pixel is a blue sub-pixel B. Data lines and gate lines in the display panel are arranged to cross each other. The sub-pixels of the three colors are alternately and repeatedly arranged in the perpendicular direction, and sub-pixels of a same color are repeatedly arranged in the horizontal direction.

[0018] In FIG. 1, the R sub-pixel, the G sub-pixel, and the B sub-pixel in each perpendicularly arranged pixel are commonly connected to a data line D1 or D2 and are respectively connected to three gate lines G1-G3 or G4-G6. Each row of sub-pixels shares one gate line and is thus sequentially driven within each frame of display period. Therefore, the display panel includes m data lines for driving 3m horizontally arranged sub-pixels and 3n gate lines for driving n perpendicularly arranged sub-pixels, thereby achieving a resolution of m×n pixels (where m and n are natural numbers). Therefore, compared with a conventional structure, the number of gate lines is tripled, but the number of data lines is reduced to one third, so one data line needs to charge sub-pixels of three colors.

[0019] Based on the above display panel, referring to FIG. 2, the present application provides a driving method for a display panel. The driving method includes: 100: acquiring a display scene of a video-source signal; 200: when the display scene of the video-source signal is a target display scene, controlling the first to i-th sub-pixels to be sequentially and alternately charged, and charging sub-pixels of one color within each frame of display period of the video-source signal.

[0020] Moreover, the display scene of a video-source signal refers to the level of refresh rate requirement for a picture display of the video-source signal. The target display scene refers to a scene where the picture display of the video-source signal has a low refresh rate requirement, for example, a static picture or a slow-moving dynamic picture. In the present application, the display scene of a video-source signal is acquired. 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 sequentially and alternately charged, and only sub-pixels of one color are charged within each frame of display period. For example, as shown in FIG. 3, only red sub-pixels are controlled to be charged in the (3n+1)-th frame, then only green sub-pixels are controlled to be charged in the (3n+2)-th frame, and only blue sub-pixels are controlled to be charged in the (3n+3)-th frame. That is, within the display period of each frame, one data line is used to charge only sub-pixels of one color. Compared to the case where one data line charges sub-pixels of three colors within the display period of each frame, the driving method for a display panel of the present application can increase the charging time of the first to i-th sub-pixels, thereby effectively alleviating the problem of uneven picture brightness of the display panel caused by insufficient sub-pixel charging.

[0021] Referring to FIG. 4, in some embodiments, step 200 specifically includes: 210: acquiring a frame rate of the video-source signal, and reducing the frame rate of the video-source signal to a target frame rate; 220: controlling the first to i-th sub-pixels to be sequentially and alternately charged according to the target frame rate, and charging sub-pixels of one color within each frame of display period of the video-source signal.

[0022] In the present application, the frame rate of the video-source signal is the actual frame rate of the video-source signal. In this embodiment, the actual frame rate of the video-source signal is taken as an initial frame rate. Moreover, the frame rate in the present application matches the refresh rate in 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 picture 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 a scanning time of each frame, and correspondingly, a charging time of each row of sub-pixels can be increased.

[0023] Referring to FIG. 5, in some embodiments, the driving method for 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 sequentially and alternately charged within one frame of display period of the video-source signal. Specifically, when the display scene of a video-source signal is a non-target display scene, that is, the picture display of the video-source signal has a high refresh rate requirement, the first to i-th sub-pixels are controlled to be sequentially and alternately charged within one frame of display period of the video-source signal to complete the picture display of the video-source signal.

[0024] Referring to FIG. 6, as an embodiment, step 300 specifically includes: 310: acquiring the frame rate of the video-source signal, and taking the frame rate of the video-source signal as an initial frame rate; 320: controlling the first to i-th sub-pixels to be sequentially and alternately charged within one frame of display period of the video-source signal according to the initial frame rate.

[0025] In this embodiment, when the picture display of the video-source signal has a high refresh rate requirement, the frame rate of the video-source signal is directly acquired and used as the initial frame rate. According to the initial frame rate, the first to i-th sub-pixels are controlled to be sequentially and alternately charged within one frame of display period of the video-source signal to realize the picture display of the video-source signal.

[0026] As an embodiment, the initial frame rate in the present application may be i times the target frame rate. If each of the plurality of pixels includes sub-pixels of three colors, i.e., i=3, the initial frame rate may be i times the target frame rate, which means the target frame rate is 1 / 3 of the initial frame rate. Then, when only sub-pixels of one color are charged within one frame of display period, it is equivalent to allocating the charging time for another two colors of sub-pixels to the sub-pixels of that one color within one frame of display period. Therefore, for an entire row of sub-pixels, the time for one gate line to charge the sub-pixels of that row becomes three times the original time. At this time, the frame rate will be reduced to 1 / 3 of the initial frame rate. Conversely, if sub-pixels of only one color are to be charged within one frame of display period, it is correspondingly necessary to reduce the frame rate of the video-source signal to 1 / 3 of the initial frame rate to obtain the target frame rate.

[0027] Referring to FIG. 7, an embodiment of the present application further provides a driving method for a display panel. The driving method includes: 101: acquiring a frame rate and a display scene of a video-source signal, and taking the frame rate of the video-source signal as an initial frame rate; 102: when the display scene of the video-source signal is a target display scene, reducing the initial frame rate to a first frame rate, controlling the first to i-th sub-pixels to be sequentially and alternately charged according to the first frame rate, and charging sub-pixels of one color within each frame of display period of the video-source signal, so that the display panel displays a picture corresponding to the video-source signal; 103: when a picture fluency displayed by the display panel controlled according to the first frame rate reaches a target fluency, storing the first frame rate as a target frame rate according to an external control instruction.

[0028] In this embodiment, during a testing phase of the display panel, a frame rate and a display scene of a video-source signal to be tested are acquired. If a refresh rate required for a picture display of the video-source signal is low, the frame rate of the video-source signal is reduced to a first frame rate. According to the first frame rate, the first to i-th sub-pixels are controlled to be sequentially and alternately charged, and sub-pixels of one color are charged within each frame of display period of the video-source signal, to cause the display panel to display a picture corresponding to the video-source signal. Subsequently, it is observed whether the fluency displayed by the display panel controlled according to the first frame rate reaches a target fluency. The target fluency is a level of picture fluency that appears smooth to the human eye. That is, if the picture perceived by the human eye is a fluent picture, the fluency of the picture reaches the target fluency. If the picture. displayed by the display panel controlled according to the first frame rate reaches the target fluency, an external control instruction may be acquired. According to the external control instruction, the first frame rate is stored as a target frame rate, so that the target frame rate can be directly retrieved and used to control the display of the display panel in subsequent operations.

[0029] Please refer to FIG. 8. In some embodiments, the driving method for a display panel further includes: 104: when the picture fluency displayed by the display panel controlled according to the first frame rate does not reach the target fluency, reducing the initial frame rate to a second frame rate, controlling the first to i-th sub-pixels to be sequentially and alternately charged according to the second frame rate, and charging sub-pixels of one color within each frame of display period of the video-source signal, such that the display panel displays a picture corresponding to the video-source signal, wherein the second frame rate is different from the first frame rate; 105: when a picture fluency displayed by the display panel controlled according to the second frame rate reaches the target fluency, storing the second frame rate as the target frame rate according to an external control instruction.

[0030] In this embodiment, when the picture fluency of the display panel controlled according to the first frame rate does not reach the target fluency, the initial frame rate is reduced to the second frame rate, which is different from the first frame rate. If reducing the initial frame rate to the first frame rate results in poor picture display quality, the initial frame rate is then further adjusted to the second frame rate. If the picture displayed by the display panel controlled according to the second frame rate reaches the target fluency, an external control instruction is acquired. According to the external control instruction, the second frame rate is stored as the target frame rate, so that the target frame rate can be directly retrieved and used to control the display of the display panel in subsequent operations. Otherwise, the initial frame rate is continuously adjusted for display testing to acquire more target frame rates for storage.

[0031] Please refer to FIG. 9. In some embodiments, the driving method for a display panel further includes: 106: acquiring a number of stored target frame rates that stored; 107: when the number of the target frame rates is less than a preset number, continuing to acquire the frame rate and the display scene of the video-source signal, and taking the frame rate of the video-source signal as the initial frame rate; 108: when the display scene of the video-source signal is the target display scene, reducing the initial frame rate to the first frame rate, controlling the first to i-th sub-pixels to be sequentially and alternately charged according to the first frame rate, and charging sub-pixels of one color within each frame of display period of the video-source signal, so that the display panel displays the picture corresponding to the video-source signal; 109: when the picture fluency displayed by the display panel controlled according to the first frame rate reaches the target fluency, storing the first frame rate as the target frame rate according to the external control instruction.

[0032] In the present application, the number of target frame rates that stored is also acquired. When the number of target frame rates that stored reaches a preset number, the testing is stopped. If the number of target frame rates is less than the preset number, testing is continued with additional video-source signals to acquire the frame rate and display scene of the video-source signal for display testing. When the display scene of the video-source signal is the target display scene, the initial frame rate is reduced to the first frame rate, and according to the first frame rate, the first to i-th sub-pixels are controlled to be sequentially and alternately charged, and sub-pixels of one color are charged within each frame of display period of the video-source signal, to cause the display panel to display the picture corresponding to the video-source signal. When the picture fluency displayed by the display panel controlled according to the first frame rate reaches the target fluency, the first frame rate is stored as a target frame rate according to an external control instruction. In other words, when the number of target frame rates is less than the preset number, steps 101 to 105 are repeated to acquire more target frame rates.

[0033] The driving method for a display panel in this embodiment is applied during the testing phase of the display panel. During the testing phase, by adjusting the frame rate of the video-source signal, the picture fluency of the display panel at the first frame rate or the second frame rate is observed. Based on the picture fluency, it is determined whether to store the first frame rate or the second frame rate as a target frame rate, thereby acquiring and pre-storing multiple target frame rates. Furthermore, when the number of target frame rates is insufficient, testing is continued with additional video-source signals to pre-store a sufficient number of target frame rates.

[0034] An embodiment of the present application further provides a driving apparatus for a display panel. The driving apparatus includes a driving module for driving the display panel to display a corresponding picture. Since the structure of the display panel has been described in detail above, a description thereof is not repeated here.

[0035] The driving module in the present application is respectively connected to the data line and the first to i-th gate lines of the display panel. The driving module is configured to, when a display scene of a video-source signal is a target display scene, control the first to i-th sub-pixels to be sequentially and alternately charged via the data line and the first to i-th gate lines, and charge sub-pixels of one color within each frame of display period of the video-source signal. This can increase the charging time of the first to i-th sub-pixels, thereby effectively alleviating the problem of uneven picture brightness of the display panel caused by insufficient sub-pixel charging.

[0036] In some embodiments, the driving module includes a controller, a gate driving unit, and a source driving unit. The gate driving unit is connected to a plurality of the first to i-th gate lines and the controller, and the source driving unit is connected to a plurality of data lines and the controller. The controller is configured to acquire the display scene of the video-source signal, and when the display scene of the video-source signal is the target display scene, reduce a frame rate of the video-source signal to a target frame rate, and output a first gate control signal, a first source control signal, and a data signal corresponding to the video-source signal according to the target frame rate. The gate driving unit is configured to respectively control the first to i-th sub-pixels to be sequentially and alternately turned on according to the first gate control signal and via the first to i-th gate lines, and turn on only sub-pixels of one color within each frame of display period. The source driving unit is configured to, when any one of the first to i-th sub-pixels is turned on, charge a corresponding sub-pixel according to the first source control signal and a data voltage corresponding to the data signal.

[0037] In some embodiments, the controller is further configured to, when the display scene of the video-source signal is a non-target display scene, take the frame rate of the video-source signal as an initial frame rate, and output a second gate control signal, a second source control signal, and the data signal corresponding to the video-source signal according to the initial frame rate. The gate driving unit is further configured to respectively control the first to i-th sub-pixels to be sequentially and alternately turned on within one frame of display period of the video-source signal according to the first gate control signal and via the first to i-th gate lines. The source driving unit is further configured to, when any one of the first to i-th sub-pixels is turned on, charge a corresponding sub-pixel according to the second source control signal and the data voltage corresponding to the data signal.

[0038] The driving module in the present application acquires the display scene of the video-source signal. When the picture display of the video-source signal has a low refresh rate requirement, the driving module controls the first to i-th sub-pixels to be sequentially and alternately charged, and charges only sub-pixels of one color within each frame of display period. Compared to a single data line charging sub-pixels of multiple colors within each frame of display period, this can increase the charging time of the first to i-th sub-pixels, thereby effectively alleviating the problem of uneven picture brightness of the display panel caused by insufficient sub-pixel charging.

[0039] Referring to FIG. 10, an embodiment of the present application further provides a display apparatus. The display apparatus includes a driving module 10 and the display panel 20 described above. Since the structure of the display panel 20 has been described in detail above, a description thereof is not repeated here.

[0040] The driving module 10 in the present application is respectively connected to the data line and the first to i-th gate lines of the display panel 20. The driving module 10 is configured to, when a display scene of a video-source signal is a target display scene, control the first to i-th sub-pixels to be sequentially and alternately charged via the data line and the first to i-th gate lines, and charge sub-pixels of one color within each frame of display period of the video-source signal. This can increase the charging time of the first to i-th sub-pixels, thereby effectively alleviating the problem of uneven picture brightness of the display panel 20 caused by insufficient sub-pixel charging.

[0041] In some embodiments, the driving module 10 includes a controller 111, a gate driving unit 112, and a source driving unit 113. The gate driving unit 112 is connected to a plurality of first to i-th gate lines and the controller 111, and the source driving unit 113 is connected to a plurality of data lines and the controller 111. The controller 111 is configured to acquire the display scene of the video-source signal, and when the display scene of the video-source signal is the target display scene, reduce a frame rate of the video-source signal to a target frame rate, and output a first gate control signal, a first source control signal, and a data signal corresponding to the video-source signal according to the target frame rate. The gate driving unit 112 is configured to, respectively control the first to i-th sub-pixels to be sequentially and alternately turned on according to the first gate control signal and via the first to i-th gate lines, and turn on only sub-pixels of one color within each frame of display period. The source driving unit 113 is configured to, when any one of the first to i-th sub-pixels is turned on, charge a corresponding sub-pixel according to the first source control signal and a data voltage corresponding to the data signal.

[0042] In some embodiments, the controller 111 is further configured to, when the display scene of the video-source signal is a non-target display scene, take the frame rate of the video-source signal as an initial frame rate, and output a second gate control signal, a second source control signal, and the data signal corresponding to the video-source signal according to the initial frame rate. The gate driving unit 112 is further configured to respectively control the first to i-th sub-pixels to be sequentially and alternately turned on within one frame of display period of the video-source signal according to the first gate control signal and via the first to i-th gate lines. The source driving unit 113 is further configured to, when any one of the first to i-th sub-pixels is turned on, charge a corresponding sub-pixel according to the second source control signal and the data voltage corresponding to the data signal.

[0043] The driving module 10 in the present application acquires the display scene of the video-source signal. When the picture display of the video-source signal has a low refresh rate requirement, the driving module 10 controls the first to i-th sub-pixels to be sequentially and alternately charged, and charges only sub-pixels of one color within each frame of display period. Compared to a single data line charging sub-pixels of multiple colors within the display period of each frame, this can increase the charging time of the first to i-th sub-pixels, thereby effectively alleviating the problem of uneven picture brightness of the display panel 20 caused by insufficient sub-pixel charging.

[0044] An embodiment of the present application further provides a television. The television includes a display panel and a driving module. Since the display panel and the driving module have been described in detail above, a description thereof is not repeated here.
