Abstract

A double-frame digital-analog-hybrid scanning strategy is proposed, and the part of digital pulse width modulation is optimized. The driving circuit of an organic-light-emitting-diode (OLED) -on-silicon microdisplay is designed, which includes the pixel driving circuit. The scanning efficiency can reach 99.22% and the data transmission frequency can be reduced to 23.328 MHz under the conditions of frame rate of 60 Hz, gray level of 256, and resolution of 1920 pixel×3 pixel×1080 pixel. The results show that this pixel driving circuit can effectively reduce the leakage current, guarantee the gray precision, reduce the minimum current, and improve the contrast of the OLED-on-silicon microdisplay.
