IPC: G06F3/044
CPC classification number: G06F3/0443
Abstract: A display device can include an optical electronic device disposed in a display area. To address a reduction of sensitivity of a touch panel disposed in a first sub-display area of the display area in which the optical electronic is disposed, an edge of a touch electrode in the first sub-display area can be provided with a finger part, a size of the touch electrode in the first sub-display area can be reduced, or a sub-touch electrode can be connected to the touch electrode in the first sub-display area, thereby increasing sensing sensitivity of the touch electrode.
