Abstract
A display driver comprises: a first grayscale line; output circuitry configured to receive a first grayscale voltage from the first grayscale line and perform digital-analog conversion on a pixel data to output a source output voltage corresponding to the pixel data, the digital-analog conversion being based on the first grayscale voltage; and first gamma assist circuitry comprising a first holding node to hold the first grayscale voltage received from the first grayscale line and configured to drive the first grayscale line based on a first voltage between the first holding node and the first grayscale line.
