摘要： A digital to analog converter of the source driver includes a gamma voltage generator and a data decoder. The gamma voltage generator receives a gamma code to generate an analog gamma voltage. The gamma voltage includes a register, a reference decoder, and a calibrator. The register stores the gamma code. The reference decoder converts the gamma code from the register into the analog gamma voltage. The calibrator, receiving a reference gamma voltage in a calibration mode, includes a comparator and a counter, in which the counter tunes the gamma code according to the control signal generated by the comparator comparing the analog gamma voltage and the reference gamma voltage. The data decoder receives digital pixel data and selects one gamma voltage as a driving voltage based on the digital pixel data.
