Title:
TOUCH CIRCUIT, TOUCH PANEL, DISPLAY PANEL AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/011013
Kind Code:
A1
Abstract:
The present disclosure provides a touch circuit. The touch circuit comprises: a first voltage input end, a second voltage input end, a pressure sensing circuit, and an output circuit. The first voltage input end is configured to input a first voltage signal, and the second voltage input end is configured to input a second voltage signal, the first voltage signal being different from the second voltage signal; an input end of the pressure sensing circuit is electrically connected to the first voltage input end, and an output end of the pressure sensing circuit is electrically connected to an input end of the output circuit; a control end of the output circuit is configured to receive a control signal; the output circuit is configured to control in response to the control signal a connection state of the input end and the output end of the output circuit. The present disclosure further provides a touch panel, a display panel, and a display device.
