Description:

Proposed is an 11-bit source driver IC for high-resolution OLED displays, utilizing a Double Capacitor Coupled Adder (DCCA) for parallel sampling and driving. A Slew Rate Enhancement (SRE) circuit ensures fast response under minimal voltage differences, while Offset Calibration minimizes inter-channel voltage deviations. Experimental results show a 2.0 ?s line time, 9.9V/?s slew rate, and a DVO of 2.43mV, showcasing precision and efficiency.
