Problems solved by technology

[0002] With the improvement of the resolution of display devices, users have higher and higher requirements for the contrast ratio of display devices. Due to the phenomenon of light leakage in the dark state of liquid crystal display panels, the contrast ratio of display devices using liquid crystal display panels is generally low.

Abstract

The present application provides a display device driving method and a display device. The method divides the backlight into a plurality of independently driven backlight units, and then acquires the brightness data of each pixel in the target display unit when displaying the target display frame, and determines the The noise data of the image to be displayed by the target display unit during the target display frame, and then determine the target brightness value of the target backlight unit corresponding to the target display unit when displaying the target display frame; based on the display corresponding to each backlight unit The content to be displayed by the unit determines the driving voltage value of each backlight unit, and the luminance of the backlight unit is dynamically adjusted according to the display content of the corresponding display unit. Especially when the display panel is dark, the backlight can be turned off, which can increase the overall brightness. The contrast of the display device when displaying an image, and the driving voltage value is related to the noise in the image, which reduces the influence of the noise on the adjustment of the luminance brightness, and can obtain a better backlight brightness value.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display device driving method and a display device. Background technique [0002] With the improvement of the resolution of the display device, users have higher and higher requirements on the contrast ratio of the display device. Due to the phenomenon of light leakage in the dark state of the liquid crystal display panel, the contrast ratio of the display device using the liquid crystal display panel is generally low. Contents of the invention [0003] The present application provides a display device driving method and a display device, so as to improve the contrast ratio of the display device using a liquid crystal display panel. [0004] An embodiment of the present application provides a method for driving a display device, the display device includes a backlight module, a liquid crystal display panel, and a main control chip, the backlight module includes...
