SHIFT REGISTER CIRCUIT AND DRIVING METHOD THEREOF, GATE DRIVER ON ARRAY CIRCUIT, AND TOUCH SENSING DISPLAY PANEL

Document Type and Number:

WIPO Patent Application WO/2018/188020

Kind Code:

A1

Abstract:

A shift register circuit (100,200) including a switch control port configured to couple to a pull-up node (PU) via two transistors (M9 and M10) in series controlled by another transistor (M8). The switch control port is configured to keep at a low voltage level during a display scan stage for the shift register circuit (100,200) to output a gate scanning signal via an output port (Output) to a gate line which optionally still transmit a touch scanning signal, to switch to a high voltage level to halt the gate scanning signal while transmitting the touch scanning signal only in the gate line during a touch scan stage within the display scan stage, and to switch back to the low voltage level after the touch scan stage to output the gate scanning signal without coupling interference of the touch scanning signal. The shift register circuit (100,200) is compatible for driving either 60Hz or high-frequency (>60Hz) Full-in-cell touch sensing display panel.
