Abstract

A driving method for a liquid crystal display. The method comprises: converting, into a second picture signal comprising a gain, a first picture signal input into a liquid crystal display, and obtaining, according to the second picture signal, a brightness gain of each pixel point in a picture displayed by the liquid crystal display, so as to obtain a brightness gain matrix (S101); calculating, according to a pre-set color cast threshold, a color cast threshold gain corresponding to the pre-set color cast threshold (S102); calculating, according to a pre-set high-brightness threshold, a high-brightness threshold gain corresponding to the pre-set high-brightness threshold (S103); correcting the brightness gain matrix according to the color cast threshold gain and the high-brightness threshold gain (S104); and driving the liquid crystal display according to the corrected brightness gain matrix (S105). The present invention can improve a backlight brightness utilization rate of a liquid crystal display and improve the color cast problem caused by the non-uniformity of a brightness gain.

Description

Technical field [0001] The present 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 human eye’s perception of the real world. The 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. The backlight must provide illumination in a way that the entire surface or a large area is illuminated. The backlight power consumption 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 the effective display brightness, and the backlight brightness utilization rate is low. Generally speaking, the brightness efficiency of RGBW monitors relative to RGB monitors is increased to 150%-200%, but at the sa...
