闡述了TFT-LCD的顯示原理、系統(tǒng)結(jié)構(gòu)和時(shí)序控制器TCON的設(shè)計(jì)方案。該模塊設(shè)計(jì)主要為減少中、小尺寸TFT-LCD時(shí)序控制器的芯片管腳數(shù)，提高通用性，與一般TCON只能驅(qū)動(dòng)2～3種分辨率的面板相比較，該設(shè)計(jì)支持8種顯示模式。實(shí)現(xiàn)對(duì)TFT-LCD面板的時(shí)序控制，產(chǎn)生源驅(qū)動(dòng)器模塊和門驅(qū)動(dòng)器模塊所需要的各種控制信號(hào)、Vcom的極性控制及顯示模式控制，實(shí)現(xiàn)對(duì)模擬RGB信號(hào)的顯示控制，源驅(qū)動(dòng)器和門驅(qū)動(dòng)器的時(shí)序控制信號(hào)可兼容多家LCD面板的時(shí)序要求。支持16:9和4:3的TFT-LCD面板。該設(shè)計(jì)可靈活應(yīng)用于市場(chǎng)上大部分的中、小尺寸TFT-LCD面板。產(chǎn)品可應(yīng)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.
