Abstract

A display driver circuit for controlling a display panel includes a first operational amplifier, a second operational amplifier and a first output switching circuit. The first output switching circuit is coupled to the first operational amplifier and the second operational amplifier. The first output switching circuit couples the first operational amplifier to a first data line of the display panel in a first scan period, to control the first operational amplifier to drive a first subpixel having a first color through the first data line. The first output switching circuit couples the first operational amplifier to a second data line of the display panel in a second scan period, to control the first operational amplifier to drive a second subpixel having the first color through the second data line.
