资料介绍

为了满足市场对 LCD面板高分辨率、窄边框的需求,面板设计引入了玻璃上集成栅极驱动设计.本文对传统液晶显示面板栅极电路设计做了介绍,分析了集成栅极驱动电路技术在实现显示面板窄边框化时的优缺点.提出了一种新型栅极驱动电路,将空间控制转化为时间控制,使用一条栅极走线控制两行甚至多行像素.模拟分析结果表明:新型栅极驱动电路在关态下会产生2.5 V的较小噪声;栅极信号的上升沿及下降沿的时间延迟总和只有3.5μs,可以实现像素节点的正常充放电并完成显示面板的正常显示.同时,本文提出的新型驱动电路可成倍减少显示面板边框栅极走线数量,减少栅极走线所占用的空间,实现高分辨率高解析度显示面板的窄边框化设计.

In order to meet the requirement of the market for LCD panel’s high resolution and narrow frame performance,the gate driver in array(GIA)employing a_Si∶H TFTs technology has emerged in recent years.This paper briefly introduced the operation principle of the traditional integrated gate driver and its effects on LCD panel design,then proposed a novel gate driving circuit through single gate to control rows of pixels,so that the number of gate lines can be sharply decreased which result in saving much more space for narrow bezel design.Simulation results show that a little noise with 2.5 V happens at off-state of the new circuit’s gate line,and ...
