Abstract :
The proposed driver circuit provides a new driver scheme for supply noise rejection and uniformity enhancement of AMOLED displays. We propose a new gamma circuit scheme for supply noise rejection improvement and provide a driver circuit with offset voltage zero-crossing detection (OZCD) technology to enhance the uniformity of larger displays. The simulation results show the supply noise rejection can improve more than 40dB, and the driver voltage output uniformity can be reduced to less than +/-1mV.
