Abstract
A touch display apparatus is provided. The touch display apparatus may include a light-emitting device and a touch sensor. The touch sensor may be disposed on an encapsulating unit covering the light-emitting device. A photo-electric device may be disposed between the encapsulating unit and the touch sensor. The photo-electric device may be disposed outside an emission area in which the light-emitting device is disposed. A light-absorbing layer of the photo-electric device may overlap at least one of touch electrodes and bridges of the touch sensor. Thus, the touch display apparatus may increase the time that the touch display apparatus is used without external power source connected by using the electrical energy generated by the photo-electric device.
