A high brightness, 0.6 inch, 800×600, mono green OLED micro-display, which based on phosphorescent materials, high efficient top-emitting structure and SVGA060 si-base CMOS backplane with full digital system driver circuit have been fabricated. The voltage of device start working is only 2.6 V, and the voltage swing as low as 2.7 V from 20 cd/m~2 to 20000 cd/m~2. When current density is 20 m A/cm~2, the green emission with peak at 535 nm and CIE coordinates X=0.286, Y=0.665. The maximun current efficiency i...
