摘要

提出了一种新型的基于In-Zn-O薄膜晶体管(IZO TFT)的行集成驱动电路。该电路采用了输入级模块复用的驱动方法

即一级输入级驱动多级输出级

因此可以显著地减少输入级模块TFT的数量

缩减电路的面积

满足高分辨率显示屏设计

同时也可以迎合显示屏窄边框的审美需求。电路的输入级模块工作时间是输出级模块的

倍(

是一级输入级模块驱动输出级模块的级数)

因此输入级尺寸可以做得更小。另外

该电路的驱动时钟频率是传统结构中一级输入级模块驱动一级输出级模块时钟频率的1/

有效地降低了电路的动态耦合功耗。我们制作了20级的行集成驱动电路

一级输入级模块驱动两级输出级模块

该电路的尺寸为宽730m

高为164m

满足窄边框的要求。从实验测结果表明

该电路很好地满足300 PPI的AMLCD或AMOLED显示屏的需求。

Abstract

This paper proposes a new gate driver circuit integrated by IZO-thin film transistors (TFTs)

which employs a new driving method called input block multiplex structure. One input block driving several output blocks is used in this method

which can reduce the number of TFTs and save the area of the circuit dramatically

satisfying the design of the high resolution and narrow bezel displays. The working time of the input block is

times as the output block

where the parameter '

' is the quantity of output blocks driven by one input block. Therefore the frequency of the driving clock of the proposed circuit is 1/

of the traditional circuits

in which one input block is used to drive one output block. We have successfully fabricated 20 stages of the circuit. The structure is one input block driving two output blocks and the dimension is 730m width and 164m height

which can realize the narrow bezel easily. The experimental results show the circuit can work well and be suitable for 300 PPI displays of AMLCD or AMOLEDs.
