Abstract
This paper presents a pixel circuit with reduced switching leakage for OLED microdisplays.A self-referenced feedback loop is dcsigned to track the node voltages for leakage reduction during the holding period.A longer holding time using a smaller storage capacitor can be achieved using the leakage reduction technique.An experimental system based on a 60 x 80 pixel matrix is fabricated in a 0.35-μm CMOS process.The area of the pixel circuit is only 15 × 15 μm2.According to the measured results,the pixel circuit achieves a holding time of longer than 500 ms and the system exhibits a satisfied accuracy and linearity within a pixel current range from 100 pA to 3 nA.关键词
