Abstract
A source driver applied in a display includes a DAC and an output buffer. The DAC receives M-bits digital input voltage and converts it into 2M analog input voltages. M is a positive integer. The output buffer with interpolating function receives the 2M analog input voltages and increases them to K analog output voltages in a N-bits interpolating way. N is a positive integer and K=2M*2N=2(M+N). The output buffer includes a positive output buffer unit and a negative output buffer unit and generates a positive interpolating voltage and a negative interpolating voltage through them respectively to share the same source output channel of the source driver and achieve linear interpolation voltage characteristics through mutual compensation between the positive interpolating voltage and the negative interpolating voltage.
