Abstract

The invention provides a pixel driving method. In the pixel driving method, through acquiring the brightness compensation value of a sub-pixel at a jth row and an ith column, whether the brightness compensation value is greater than a preset threshold is determined. When the brightness compensation value is less than or equal to the preset threshold, a current display frame can be known not to bea heavy load frame so that the brightness value does not need to be compensated and the brightness value at the jth row and the ith column can be directly output. When a brightness compensation valueis greater than the preset threshold, the current display frame can be known to be the heavy load frame, the brightness value after sub-pixel compensation at the jth row and the ith column is output according to the target brightness value of the sub-pixel at the jth row and the ith column and the brightness compensation value, and the heavy load frame is converted into a light load frame. A problem that the temperature of a source driver is too high under the heavy load frame is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving method. Background technique [0002] Thin Film Transistor (TFT) is the main driving element in current Liquid Crystal Display (LCD) and Active Matrix Organic Light-Emitting Diode (AMOLED). It is related to the display performance of the flat panel display device. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to pour liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate) and the color filter (ColorFilter, CF) substrate, and apply pixel voltage on the two substrates respectively. and the common voltage, through the electric field formed between the pixel voltage and the common voltage to c...
