Abstract

An active matrix display device includes a base plate, a scan line, a signal line, a switch unit, a pixel unit and a grid drive IC, among which, said scan line and the signal line are arrayed on the base plate, said switch is connected with the pixel unit and at the cross point of the scan line and the signal line and connected with it, among which, a multi-path drive circuit includes a low level DC signal source, n-functional control signal lines and 2n film transistors, in which, the grid of every two film transistors is connected with each functional control signal line to form a set, said low level DC signal source is connected with the source of a film transistor in said set to transmit low level signals, the source of the other film transistor in said set is connected with an output pin of said grid drive IC to transmit the drive signals, the drain of each transistor is connected with said scan line to transmit said drive signal.

Description

【Technical field】 [0001] The invention relates to an active matrix display device. 【Background technique】 [0002] As we all know, flat-panel displays have gradually become the mainstream of display interfaces at this stage, regardless of plasma displays (Plasma Display Panel, PDP), liquid crystal displays (Liquid Crystal Display, LCD), organic electroluminescence displays (Organic electroluminescence Display, OLED), field emission displays ( Field Emission Display (FED) or liquid crystal technology (Liquid Crystal on Silicon, LCOS) display has great development in various application fields, from small size for mobile phones to large size for home or video TV potential. In order to meet the quality requirements of high image quality and high definition, the active matrix method will become the main force of flat panel displays in the future. Whether the active matrix driving method uses an external driver IC (Integrated Circuit, integrated circuit) or uses System On Glass...
