Abstract

The invention provides a liquid crystal displayer (LCD) driving method. The liquid crystal displayer (LCD) driving method comprises steps of converting a first image signal inputted into an LCD to a second image signal comprising a gain, obtaining a brightness gain of each pixel point in the image displayed by the LCD according to the second image signal, obtaining a brightness gain matrix, calculating a color cast threshold gain corresponding to a preset color cast threshold according to the preset color cast threshold, calculating a high brightness threshold gain corresponding to a preset high brightness threshold according to the preset high brightness threshold, performing correction on the brightness gain matrix according to the color cast threshold gain and the high brightness threshold gain, and driving the LCD according to the corrected high brightness gain matrix. The technical scheme provided by the invention can improve a LCD backlight brightness utilization rate and can improve color cast caused by non-uniformity of brightness gain. The invention also provides an LCD driving system and a computer readable storage medium.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display driving method, system and computer-readable medium. Background technique [0002] The core of display technology is to reproduce the perception of the real world by human eyes. Among them, LCD display technology has mature technology, low cost, and high reliability. However, the brightness of any display pixel of LCD cannot be controlled at the pixel level. It can only be controlled by The backlight must provide illumination in the form of full-surface or large-area lighting. The power consumption of the backlight accounts for about 80% of the power consumption of the entire display panel, but more than 90% of the light is blocked or absorbed and fails to contribute to effective display brightness, and the utilization rate of the backlight brightness is low. Generally speaking, the brightness efficiency of RGBW display is increased to 150%-200% compare...
