Abstract
The driver IC includes: a control circuit operable to perform control for creating the timing of detection by a touch panel in a non-display drive period during which the action of a drive circuit remains stopped, and for creating a display drive period during which the drive circuit drives the display panel, and the non-display drive period; and a data RAM operable to hold display data of more than one display line, but smaller than one display frame in capacity. The control circuit performs control for alternately creating the display and non-display drive periods by repeating a memory-addressing operation for writing display data supplied from outside into the RAM and reading the display data from the RAM at a speed faster than the writing speed to provide the read data to the drive circuit two or more times in a period of one display frame according to a wraparound method.
