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.

Abstract: The series regulator has: a differential amplifier; a level shifter including a level shift transistor with a drain connected to a gate; and a source follower including an output transistor. The differential amplifier includes an amplification stage having a non-inverting input terminal for input of a reference voltage, an inverting input terminal for input of a feedback voltage, and an amplifier output terminal. The differential amplifier has a DC operation point where an error of an output voltage at the amplifier output terminal to an input voltage to the non-inverting input terminal is equal to or under a gate-source voltage of an input transistor, and a follower output terminal of the source follower is feedback-connected to the inverting input terminal. The level shifter performs a level shift to make an output voltage of the source follower coincident with the voltage at the amplifier output terminal of the differential amplifier.
