Embodiment Construction
[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0043] Embodiments of the present invention provide a driving method, which is applied to a liquid crystal display panel.
[0044] The liquid crystal display panel is usually powered by alternating current, so the light emitted by the backlight source changes light and dark at a certain frequency, which causes the light entering the liquid crystal display panel to change light and dark alternately at a certain frequency. like figure 1 As ...

The present invention provides a driving method, a driving device, a display device and a computer-readable storage medium. The driving method is applied to a liquid crystal display panel, and the driving method includes the following steps: determining the brightness level of each sub-region according to the backlight brightness of each sub-region; obtaining a voltage adjustment relationship corresponding to the brightness level of each sub-region; The relationship determines the drive voltage for each pixel in each sub-region. The liquid crystal display panel of the embodiment of the present invention includes a plurality of sub-regions. During implementation, the corresponding voltage adjustment relationship is determined according to the brightness of each sub-region, and when the display gray scale is the same, the driving voltage of the pixel in the sub-region with the high brightness level is determined. Greater than the driving voltage of pixels in sub-regions with low brightness levels can offset the increase in RC delay caused by the increase in brightness, thereby helping to improve the consistency of charging rates in sub-regions with different brightness levels and reducing the appearance of waterfall blocks in the LCD panel. Shows the possibility of undesirable phenomena.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a driving method, a driving device, a display device and a computer-readable storage medium. Background technique [0002] The backlight brightness distribution uniformity of large-size LCD (Liquid Crystal Display) panels is relatively poor. Some large-size LCD panels also have a Local Diming (backlight area adjustment technology) function to adjust the backlight brightness. Local Diming refers to It divides the image signal into several areas in the LCD TV system, and analyzes and calculates the brightness of the image in each area, and then automatically controls the brightness of the backlight in each area. [0003] The characteristics of the TFT Active tail area (the end of the active layer of the thin film transistor) of the pixel unit inside the LCD panel are changed due to the influence of light. When there is light, the conduction of the Active tail increase...
