The invention discloses a self-capacitance organic light emitting touch display apparatus. The 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 control unit, and a touch control unit. During touch sensing, the touch control unit sequentially or randomly applies a capacitance exciting signal to a selected touch sensing electrode, and senses a touch sensing signal at the selectedtouch sensing electrode. The touch control unit applies a shielding reflection signal to the common electrode layer or a reference point of the display control unit. When self-capacitance organic light emitting touch display apparatus performs the touch detection operation, no common current loops exist between the display control circuit and the touch control circuit, thus being able to avoid the influence of noise from the display control circuit.
