Abstract
A mutual-capacitance organic light emitting touch display apparatus includes a thin film transistor substrate, a common electrode layer, an organic light emitting material layer, and at least a touch electrode layer, including a plurality of first touch electrodes arranged along a first direction, and a plurality of second touch electrodes arranged along a second direction; a thin film encapsulation layer; a display controller having a display power source, and electrically connected to a thin film transistor, a pixel electrode and the common electrode layer of the thin film transistor substrate; and a touch controller including a touch power source. The touch controller applies a touch driving signal to a selected first touch electrode, and senses a touch sensing signal at a second touch electrode, and outputs the touch sensing signal to the common electrode layer or a reference point of the display controller by a non-inverting amplifier.
