Abstract

The invention provides a driving device of an LCD (Liquid Crystal Display), comprising a plurality of grid driving integrated circuits, a plurality of regions partially corresponding to the LCD and a grid clock signal generating module. The grid clock signal generating module outputs grid partition clock signals to the plurality of grid driving integrated circuits, scans the plurality of regions in an acyclic mode and comprises a grid line appointed pulse generating module and a partition clock signal selecting module. The invention provides a scanning method that, the panel is divided into the plurality of regions by using a specific scanning sequence of the LCD panel and grid lines are disorderly arranged in space. According to the method, the scanning time sequence is dispersed into the whole map boundary to solve a phenomenon of panel brightness unevenness.

Description

technical field [0001] The invention relates to a driving method of a thin film transistor liquid crystal display, in particular dividing a panel into a plurality of areas and generating a specific scanning sequence for these areas. Background technique [0002] Liquid crystal display uses an electric field applied to the liquid crystal material to change its rotation angle to control the color and brightness of the pixels. [0003] Each pixel (pixel) of the liquid crystal display panel has a pixel transistor, and the gate of the pixel transistor is connected to the gate line controlled by the above-mentioned gate drive integrated circuit; the source is connected to the gate line controlled by the above-mentioned source drive integrated circuit. The data line is connected; and the drain is connected to the pixel. Each pixel mentioned above has a common electrode for applying a common voltage. The gate driving integrated circuit applies voltages to the gate lines in a certa...
