Abstract
The present invention discloses an OLED touch control display device and driving method thereof. The OLED touch control device of the present disclosure sets a transparent touch control electrode and a second thin film transistor in the pixels, a gate of the second thin film transistor is connected to a scanning line corresponding to the pixels, a source is coupled to the touch control lines, a drain is coupled to the touch control electrode. During driving state, a scanning signal is sequentially transmitted to the plurality of scanning lines in each frame period, and a touch control chip used to charge the plurality of touch control lines in one of two adjacent frame periods, and receive a touch control signal transmitted by the plurality of touch control lines in the other of any two adjacent frame periods, thereby achieving high-sensitivity touch sensing, high module yield, and low product cost.
