Abstract:
A display driver IC prototype for mobile full‐HD AMOLED display is presented. Since full‐HD AMOLED display has too short driving time, conventional R‐string DAC column driver cannot obtain enough internal settling time. To solve the problem, therefore, a new R‐string DAC column driver architecture is proposed, which has much faster settling time with high accuracy. Also, with the architecture, one 8‐bit PTL in conventional R‐string DAC is replaced with much smaller two sub‐PTLs, decreasing the overall driver area. The measured INL and DNL are 0.49 LSB and 0.38 LSB, respectively. The mean and maximum value of inter‐channel DVO is 4.6mV and 7mV, respectively. The proposed linear 10‐bit DAC fabricated on 90‐nm CMOS process occupies 81% of conventional nonlinear 8‐bit R‐string DAC area in the same technology.
