DISPLAY DEVICE WITH TOUCH DETECTION FUNCTION AND ELECTRONIC APPARATUS INCLUDING SAME

摘要

According to an aspect, a display device with a touch detection function includes: a pixel electrode; a touch detection electrode; a display drive unit for outputting the pixel signal to the pixel electrode in synchronization with a display drive signal; an operation drive unit for supplying the display drive signal in a display operation period to perform a display operation and supplying a touch detection drive signal in a touch detection period to perform a touch detection operation; a touch detection unit for detecting a detection signal outputted from the touch detection electrode; and a control unit for executing the display operation period and the touch detection period in a time divisional manner. The touch detection unit performs a noise detection operation for detecting a disturbance noise superimposed on the touch detection electrode in the display operation period.

1. A display device with a touch detection function comprising:
a pixel electrode to which a pixel signal is applied to allow a display element to perform a display operation; a touch detection electrode for detecting whether an external object is in contact with or in proximity to the display device; a display drive unit for outputting the pixel signal to the pixel electrode in synchronization with a display drive signal so as to perform the display operation; an operation drive unit for supplying the display drive signal in a display operation period to perform the display operation and supplying a touch detection drive signal in a touch detection period to perform a touch detection operation; a touch detection unit for detecting a detection signal outputted from the touch detection electrode; and a control unit for executing the display operation period and the touch detection period in a time divisional manner, wherein the touch detection unit performs a noise detection operation for detecting a disturbance noise superimposed on the touch detection electrode in the display operation period.
