Document Type and Number:
WIPO Patent Application WO/2022/057019
Kind Code:
A1
Abstract:
A touch-control display panel, comprising a thin-film transistor substrate, a light-emitting layer, an encapsulation layer, and a touch-control layer. The light-emitting layer comprises a cathode, and the touch-control layer comprises a plurality of touch-control sensing electrodes arranged in the same layer, wherein the plurality of touch-control sensing electrodes are connected to a plurality of touch-control signal lines in one-to-one correspondence; the plurality of touch-control signal lines are connected to a touch-control chip; a coupling capacitance is formed between the touch-control sensing electrodes and the cathode; and the touch-control chip determines, by means of detecting a change in the coupling capacitance, whether there is a touch-control operation.
