Embodiment Construction

[0023] Please refer to FIG. 4 , which is a schematic diagram of a liquid crystal display driven by the first embodiment of the liquid crystal display driving method of the present invention. The liquid crystal display 20 includes a plurality of scanning lines 201 parallel to each other, a plurality of data lines 202 parallel to each other and vertically insulated and intersecting with the scanning lines 201 , a scanning driving circuit 210 , a data driving circuit 220 and an LED array 240 . The scan driving circuit 210 is used to drive the scan lines 201 . The data driving circuit 220 is used to drive the data line 202 .

[0024] The LED array 240 includes a plurality of red LEDs 241 , green LEDs 242 and blue LEDs 243 arranged periodically. The LED array 240 can emit red light, green light and blue light respectively within a frame time. The scan line 201 and the data line 202 intersect to define a plurality of pixel units 205 . Since the light-emitting diode array 240 can ...

Abstract

This method includes: (1) dividing a frame into three time sub-section (TTS); (2) the LBD array irradiating respectively red, green and blue lights during TTS; (3) the data driving circuit controlling the intermittent ratio of the voltage applied on the data line to control the bright / dark time ratio of the pixel to further control the grayness of red, green and blue lights of pixel.

Description

technical field [0001] The invention relates to a liquid crystal display driving method. Background technique [0002] Due to the advantages of lightness, thinness, and low power consumption, liquid crystal displays are widely used in modern information equipment such as televisions, notebook computers, mobile phones, and personal digital assistants. Currently, the application of liquid crystal displays in the market is becoming more and more important. [0003] Please refer to FIG. 1 , which 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 circuit 110 is used to drive the scan lines 101 . The data dri...
