Abstract

The invention relates to a driving method to drive display device to display image data. The device includes backlight module and plural liquid crystal pixels. And the backlight module contains plural light emitting brightness levels. The driving method includes following steps: separating the image display section to plural sub-display sections, when liquid crystal open or close at the display section, the backlight would open or close at the sub-display section, controlling the switch state of the liquid crystal pixel and light emitting brightness level of backlight module and light emitting time to realize gray scale display. The invention could make the image of LCD device equal.

Description

【Technical field】 [0001] The invention relates to a driving method of a liquid crystal display device. 【Background technique】 [0002] Due to the advantages of light weight, thin thickness, and low power consumption, liquid crystal display devices are widely used in modern information equipment such as televisions, notebook computers, mobile phones, and personal digital assistants. [0003] A prior art liquid crystal display device can refer to FIG. 1, the liquid crystal display device 100 includes n rows of scan electrodes 101 parallel to each other, m columns of data electrodes 102 parallel to each other and vertically insulated from the n rows of scan electrodes 101, and multiple A thin film transistor (Thin Film Transistor, TFT) 104 is used as a switching element to drive the pixel electrode 103 . The plurality of thin film transistors 104 are located at the intersection of the scan electrode 101 and the data electrode 102, the gate 1040 of the thin film transistor 104 ...
