Abstract

The present invention relates to a liquid crystal display driving method, which includes dividing a frame into three sub-periods and three blank periods, the blank period and the sub-period are spaced apart from each other, and each blank period lags behind the corresponding sub-period. During the three sub-periods, a LED array emits red light, green light and blue light respectively, and during any blank period, the LED array emits red light, green light and blue light simultaneously. The liquid crystal display driving method can effectively solve the problem of low display brightness of the liquid crystal display.

Description

technical field [0001] The invention relates to a liquid crystal display driving method. Background technique [0002] At present, liquid crystal displays have gradually replaced traditional cathode ray tube (Cathode Ray Tube, CRT) displays used in computers, and because liquid crystal displays are light, thin, and small, they are very suitable for use in desktop computers, notebook computers, In personal digital assistant (Personal Digital Assistant, PDA), mobile phone, TV and various office automation and audio-visual equipment. [0003] see figure 1 , is a schematic diagram of a prior art liquid crystal display. The liquid crystal display 10 includes a plurality of scanning lines 101 parallel to each other, a plurality of data lines 102 parallel to each other and vertically insulated and intersected with the scanning lines 101, a scanning driving circuit 110, a data driving circuit 120 and a light emitting diode (Light Emitting Diode, LED) array 140 . The scan driving...
