摘要:
A display driving circuit includes a digital-to-analog converter configured to convert a digital image signal to an analog image signal, and a buffer circuit configured to receive the analog image signal and to output an output signal to be applied to a data line, where the buffer circuit includes an input stage configured to receive the analog image signal and to output a first signal, a first output stage configured to receive a first voltage and a second voltage and to output the output signal, a second output stage configured to receive a third voltage and a fourth voltage and to output the output signal, and a selection circuit configured to apply the first signal from the input stage to the first output stage or the second output stage in response to a mode signal.
