Embodiment Construction
[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0043] An embodiment of the present invention provides a driving method 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 bright and dark at a certain frequency, which causes the light entering the liquid crystal display panel to also alternately change bright and dark at a certain frequency. Such as figure 1 As shown, a l...

The invention provides a driving method, a driving device, a display device and a computer readable storage medium. The driving method is applied to the liquid crystal display panel, and comprises thefollowing steps: determining the brightness level of each sub-region according to the backlight brightness of each sub-region; obtaining a voltage regulation relationship corresponding to the brightness level of each sub-region; and determining the driving voltage of each pixel in each sub-region according to the voltage regulation relationship. The liquid crystal display panel provided by the embodiment of the invention comprises a plurality of sub-regions, during implementation, a corresponding voltage regulation relationship is determined according to the brightness of each subarea; underthe condition that the display gray scales are the same, the driving voltage of the pixel in the subarea with the high brightness level is greater than the driving voltage of the pixel in the subareawith the low brightness level; RC delay increase caused by brightness increase can be counteracted, so that the consistency of charging rates of sub-regions with different brightness can be improved,and the possibility of poor display of waterfall-shaped blocks of the liquid crystal display panel is reduced.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a driving method, a driving device, a display device and a computer-readable storage medium. Background technique [0002] The uniformity of backlight brightness distribution of large-size LCD (Liquid Crystal Display, liquid crystal display) panels is relatively poor, and some large-size LCD panels also have the function of Local Diming (backlight area adjustment technology) to adjust the brightness of the backlight. Local Diming refers to In the LCD TV system, the image signal is divided into several areas, and the image brightness of each area is analyzed and calculated, and then the brightness of the backlight in each area is automatically controlled. [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 change due to the influence of light. When there is light, the con...
