Abstract
The drive control device includes a display control part and a touch control part. The display control part includes a control circuit operable to control first and second frame modes, and a clock pulse generator operable to produce a display line clock signal in synchronization with a display line switching cycle. The control circuit changes display and non-display drive terms in start timing on an individual display frame period basis in the first frame mode. In the second frame mode, each display frame period includes only one display drive term; the display drive term is not interrupted by a non-display drive term halfway. The second frame mode is arranged so that the cycle of the display line clock signal in synchronization with the display line switching cycle is made longer than that in the first frame mode.
