Abstract
A self-capacitance organic light emitting touch display apparatus includes a thin film transistor substrate, a common electrode layer, an organic light emitting material layer, at least a touch electrode layer including a plurality of touch sensing electrodes, a display controller, and a touch controller. During touch sensing, the touch controller sequentially or randomly applies a capacitance exciting signal to a selected touch sensing electrode, and senses a touch sensing signal at the selected touch sensing electrode. The touch controller applies a shielding reflection signal to the common electrode layer or a reference point of the display controller.
