闡述了TFT-LCD的顯示原理、系統結構和時序控制器TCON的設計方案。該模塊設計主要為減少中、小尺寸TFT-LCD時序控制器的芯片管腳數，提高通用性，與一般TCON只能驅動2～3種分辨率的面板相比較，該設計支持8種顯示模式。實現對TFT-LCD面板的時序控制，產生源驅動器模塊和門驅動器模塊所需要的各種控制信號、Vcom的極性控制及顯示模式控制，實現對模擬RGB信號的顯示控制，源驅動器和門驅動器的時序控制信號可兼容多家LCD面板的時序要求。支持16:9和4:3的TFT-LCD面板。該設計可靈活應用于市場上大部分的中、小尺寸TFT-LCD面板。產品可應用于車載電視、便攜式DVD等。

Abstract:

?This paper described the display principle of TFT-LCD， system architecture and design of timing controller TCON. The module was designed primarily to reduce chip pins in the medium and small size TFT-LCD timing controller and to increase universality， The design supported eight display modes， and the general TCON only can drive 2～3 kinds of resolution panel. This design achieved timing control of the TFT-LCD panel produced all the required control signals in the source drive module and gate drive module， and realized Vcom polarity control and display mode control， and the display control of the analog RGB signal. The source driver and gate driver timing control signal are compatible with a number of LCD panel timing requirements， and support 16:9 and 4:3 TFT-LCD panel. The design can be applied flexibly on the most medium and small size TFT-LCD panel in the market. Products can be used in vehicle TV， portable DVD and so on.
