Title:
OLED TOUCH DISPLAY DEVICE AND DRIVING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/220508
Kind Code:
A1
Abstract:
An OLED touch display device and a driving method therefor. The OLED touch display device is provided in a pixel (20) with a light-transmitting touch electrode (22) and a second thin-film transistor (T2), a grid electrode of the second thin-film transistor (T2) is connected to a scanning line (30) corresponding to the pixel (20), a source is electrically connected to a touch line (50), a drain is electrically connected to the touch electrode (22); during driving, sequentially transmitting, within each frame period, scanning signals to the plurality of scanning lines (30), charging, in one of any two adjacent frame periods, the plurality of touch lines (50) by means of a touch chip (60) and receiving, in the other one of the any two adjacent frame periods, touch signals transmitted by the plurality of touch lines (50), thereby achieving high-sensitivity touch sensing, high yield of the module and low product cost.
