| 摘 要： | 在电流编程像素电路的基础上提出了一种新的交流驱动电路结构.该电路结构不仅能实现OLED的交流驱动,而且能避免由于制作过程的变化和长时间的工作引起的驱动管阈值电压漂移的现象,这种现象将导致OLED显示屏的亮度不一致.另外这种驱动方式还能消除在反偏脉冲起始和结束时刻的尖峰电流.最后,用AIM-SPICE软件对电路进行了仿真,仿真结果表明OLED器件在恢复时间内处于反偏状态.

| Abstract: | A new,improved pixel-driving circuit is presented based on a current-programmed pixel circuit in order to achieve an AC-driving mode.This driving method realizes an AC-driving mode,removes the threshold voltage variation of the driving TFT due to the process variation or long-term operation,which can bring about brightness non-uniformity,and eliminates high peak pulse currents at the beginning and end of recovery time.Simulation is done with AIM-SPICE,and simulation results demonstrate that the OLED is in the reverse-biased state during recovery time. |
