OLED的无源驱动技术
Driving Technology for PMOLED
摘要
主要介绍了有机发光二极管(OLED)的无源驱动技术.分析了无源驱动电路的特点和驱动电路,即利用程控恒流源驱动OLED,达到不同灰度的显示.重点讨论了利用预充电技术提高无源OLED器件亮度的均匀性.
Abstract
Driving technology for PMOLED is introduced in this paper. The driving characteristic and circuit of PMOLED are analyzed. In order to get the goal of multi gray-scale, the programmable constant current source is used to drive PMOLED. Pre-charge technology is applied in driving circuit of PMOLED to improve the uniformity of brightness of PMOLED.
