Abstract: Each of frame display periods is for performing a display operation based on image information on one frame and each of detection surface touch detection periods is from when touch detection is started to when the detection is completed on the entire detection surface. At least one frame display period of the frame display periods and at least one detection surface touch detection period of the detection surface touch detection periods are started based on a display synchronization signal. The display operation and the touch detection operation are performed in a time-division manner in the one frame display period. The length of the one detection surface touch detection period is longer than the one length of the frame display period.

Abstract: A display device includes an image processing unit that performs image processing on image data input from the outside, and performs display output corresponding to the image data on which image processing is performed by the image processing unit. The image processing unit includes a first processing circuit that simply replaces colors of an image to limit the number of colors used for the image to a predetermined number equal to or smaller than 16, a second processing circuit that performs image processing including arithmetic processing for improving luminance of a plurality of pixels constituting the image displayed on the display device corresponding to the image data; and a switching unit that causes the second processing circuit to perform image processing, and causes the first processing circuit to perform image processing when performing the image processing while saving more power than the second processing circuit.
