Display driver, electro-optical device, and control method for display driver

摘要

A display driver includes: a data input section to which display data or command data is input; a display processing section which includes a data line driver section driving the data lines based on the display data input through the data input section; a control register for controlling the display processing section; a command signal generation section which generates a command signal which changes at a predetermined timing and is used to identify the command data; a command extraction section which extracts the command data from data such as the display data input through the data input section based on the command signal; and a decoder which decodes the command data extracted by the command extraction section. A value corresponding to a decoding result of the command data is set in the control register. The display processing section is controlled based on the value set in the control register.
