Abstract
The display driver includes an image memory which is configured by including a plurality of memory mats, a plurality of power supply switches which can perform an ON and OFF control of power supply to each of the plurality of memory mats, and a control circuit which turns on or off the power supply switches. The control circuit turns on the plurality of power supply switches in such a manner that the power supply to the memory mat to which the image data is written at an initial time, among the plurality of memory mats, becomes stable earlier than the power supply to the other memory mats.
