摘要

根据最基本的2T1C像素电路

建立了TFT各参数与AMOLED面板限制因素的计算模型。详细分析了AMOLED显示尺寸与TFT迁移率、金属方块电阻、刷新频率以及器件结构的关系。在大尺寸高分辨率AMOLED面板设计中

信号线RC延迟是主要限制因素。TFT迁移率的提高在一定范围内对大尺寸显示面板设计有利

降低RC延迟是实现大尺寸、高分辨率、高刷新频率显示的关键技术。开发铜布线技术和低寄生电容TFT器件结构是未来大尺寸AMOLED显示的关键技术。

Abstract

According to the basic 2T1C pixel circuit

the calculation model of AMOLED panel and TFT parameters was established. The relationships of AMOLED display size with mobility of TFT

metal sheet resistance

refresh rate and TFT device structure were analyzed in detail. In the design of large size high resolution AMOLED panel

RC delay of signal line is the main limiting factor. The enhancement of TFT mobility is benefit for large size display panel within a certain range. Reducing the RC delay is the key technology to realize the large size

high resolution

high refresh rate display. Developing the copper wiring technology and TFT device structure with low parasitic capacitance is the key technology of large size AMOLED display in the future.
