摘要： A touch panel system includes a touch panel including a drive electrode, a position detection electrode, and a pressing detection electrode, and a controller configured to impart a drive signal to the drive electrode and acquire signal values from each of the position detection electrode and the pressing detection electrode. The controller detects a position of an indicator on the basis of the signal values obtained from the position detection electrode and calculates a magnitude of pressing of the indicator on the basis of signal values in a pressing detection range corresponding to the detected position of the indicator among the signal values obtained from the pressing detection electrode.

摘要： A display device includes pixel electrode groups and a touch detection driver. During a period, the touch detection driver does not supply touch detection driving signals to a transmitter electrode overlapping in plan view a pixel electrode group to which gate signals are being supplied, and supply touch detection driving signals to a transmitter electrode disposed so as to overlap in plan view a pixel electrode group to which gate signals are not being supplied.

摘要： A touch panel include a cover member, a drive electrode, a pressure detecting electrode, and a position detecting electrode. The pressure detecting electrode and the position detecting electrode are alternately arranged in a first direction. The pressure detecting electrode includes a plurality of pressure detecting sections, arranged side by side in a second direction orthogonal to the first direction, that each independently detect a pressure. The position detecting electrode includes a plurality of position detecting sections, arranged side by side in the second direction, that each independently detect a touched position. The area of a pressure detecting section is larger than the area of a position detecting section.
