Abstract

A display driver includes a drive circuit that receives input of a first reference voltage to an nth reference voltage (where n is an integer of two or more), and outputs a drive voltage that is based on a grayscale voltage obtained by voltage division of an ith reference voltage and an (i+1)th reference voltage (where i is an integer of n−1 or less), and a control circuit that utilizes frame rate control on first display data corresponding to a grayscale voltage obtained by voltage division of the first reference voltage and a second reference voltage to generate second display data, and supplies the second display data to the drive circuit.
