Driving circuit of liquid-crystal displaying device

Abstract

A driving circuit of liquid crystal display is prepared as using multiple gate electrode driver to drive multiple film transistors selectively, using multiple source electrode driver to receive video signal for displaying on display, having adjustable shared voltage generating circuit set on each source electrode driver and outputting the same voltage by these circuits, using time - sequence controller to provide control signal and data to both driver and to provide adjustable data to voltage generating circuit.

Description

technical field [0001] The present invention relates to a driving circuit of a liquid crystal display, and in particular to a driving circuit capable of uniformly distributing a common voltage. Background technique [0002] In recent years, due to the great progress and development of the image display technology, a large part of the traditional cathode ray display has been replaced by the so-called panel display. The panel display is generally a thin-film transistor liquid crystal display (TFT-LCD). In addition, panel displays using light emitting diodes or plasmas have become increasingly popular. [0003] The display part of the panel display is composed of a pixel array. The pixel array is generally a determinant matrix, and the pixels are controlled by a driver, and the corresponding pixels are driven according to the dot-matrix image data. The pixel is controlled by the driver, and the specified color will be displayed at the specified moment. [0004] In a liquid ...
