US 10,592,059 B2 · Touch sensor overlapping a display

Abstract

According to an aspect, a display device with a touch sensor has a display function and a touch sensor function. The display device includes: a panel unit that comprises a first substrate, a second substrate, and a display function layer between the first substrate and the second substrate; a first electrode on the first substrate; a second electrode on the second substrate; a third electrode on the second substrate; and a capacitor for the touch sensor function. The capacitor is formed between either of the first electrode and the second electrode and the third electrode, or between both the first electrode and the second electrode and the third electrode. The frame portion outside the display area comprises, on the first substrate side thereof, a peripheral circuit, and the second electrode is provided in a position more distant upward from the peripheral circuit than the first electrode.

Dependent claims

A touch sensor overlapping a display, the display having a display area and a frame area outside the display area, the touch sensor comprising:

a touch detection electrode on a front surface side of a substrate,
a first touch drive electrode disposed at a back surface side of the substrate;
a second touch drive electrode disposed at the back surface side of the substrate,
wherein
the first touch drive electrode is overlapped by the touch detection electrode in plan view,
the first touch drive electrode is disposed in an inner area that faces the display area of the display, and
the second touch drive electrode is disposed in an outer area that faces the frame area of the display,
a first layer in which the first touch drive electrode is provided is different from a second layer in which the second touch drive electrode is provided, and
the first touch drive electrode and the second touch drive electrode are supplied with a same potential.
