表示システム、制御装置および制御方法
Document Type and Number:
Japanese Patent JP7407402
Kind Code:
B2
Abstract:
A display device includes multiple common electrodes. A drive circuit supplies a reference voltage for image display during a display period, for which the display device displays an image, and supplies a touch drive signal during a touch detection period, to each of the multiple common electrodes. A touch detection circuit performs detection of a touch by an object on the display device, during a touch detection period. A selector selects, as an operation mode of the display system, a first mode or a second mode. The first mode is an operation mode in which the display period and the touch detection period are alternately arranged within each of multiple successive frame periods of the display device. The second mode is an operation mode in which, during at least one frame period, the display device displays an image while the touch detection circuit stops touch detection.
