High-speed low-power voltage-programmed driving scheme for AMOLED displays

A new voltage-programmed driving scheme named the mixed parallel addressing scheme is presented for AMOLED displays, in which one compensation interval can be divided into the first compensation frame and the consequent N-1 post-compensation frames without periods of initialization and threshold voltage detection. The proposed driving scheme has the advantages of both high speed and low driving power due to the mixture of the pipeline technology and the threshold voltage one-time detection technology. Corresponding to the proposed driving scheme, we also propose a new voltage-programmed compensation pixel circuit, which consists of five TFTs and two capacitors(5T2C). In-Zn-O thin-film transistors(IZO TFTs) are used to build the proposed 5T2C pixel circuit. It is shown that the non-uniformity of the proposed pixel circuit is considerably reduced compared with that of the conventional 2T1C pixel circuit. The number of frames(N) preserved in the proposed driving scheme are measured and can be up to 35 with the variation of the OLED current remaining in an acceptable range. Moreover, the proposed voltage-programmed driving scheme can be more valuable for an AMOLED display with high resolution, and may also be applied to other compensation pixel circuits.     

全N型TFT ESD瞬态检测电路的设计

为适应有源发光二极管显示(AMOLED)以及有源液晶显示(AMLCD)技术的发展,使用三级反向器反馈结构设计了一种全N型的TFT静电放电(ESD)瞬态检测电路,并采用对比仿真研究的方式分析该电路的性能优劣.结果显示:反馈器件一方面可以提高各功能器件的转换速度,以保证箝位器件能够及时打开与关闭,避免因长时间流过大电流而引起箝位器件失效;另一方面可以控制箝位器件栅极电压的保持时间,从而满足不同电路的需求;三级反向器可以稳定箝位器件的栅极电压波形,有利于电路功能的更好实现.该设计满足基本ESD检测电路的相关参数要求,并且提高了电路的总体性能.
