Abstract
A display driver includes a processing circuit that performs gray level gamma conversion processing on display data, a memory that stores correspondence information, and a drive circuit. The memory stores lower n bits of m-bit output gray level data in an output gray level group, the processing circuit generates output gray level data corresponding to the m-bit input gray level data based on lower n-bit data, and the drive circuit outputs a drive voltage based on the output gray level data.
