Shift register and touch device

摘要

A touch device includes gate lines, pixels, sense control lines and sense units. Each pixel is connected to one of the gate lines and is decided whether to receive data according to a voltage on the gate line. Each the sense unit is connected to one of the sense control lines and is decided whether to perform a touch sense operation according to a voltage on the sense control line. The touch device further includes a shift register string including cascade-connected shift registers. Each shift register has first and second output terminals. The first output terminal provides an output to one of the gate lines according to a first clock signal to control the voltage on the gate line. The second output terminal provides an output to one of the sense control lines according to a second clock signal to control the voltage on the detection control line.

主权项

1. A shift register comprising:
a pull-up module, electrically coupled to receive an input signal to thereby deliver the input signal to an output terminal of the pull-up module; an output module, comprising a first output terminal and a second output terminal, wherein the output module is electrically coupled to receive a first clock signal and a second clock signal different from each other, the output module further is electrically coupled to the output terminal of the pull-up module to thereby determine whether to provide the first clock signal and the second clock signal respectively to the first output terminal and the second output terminal according to a voltage on the output terminal of the pull-up module; and a stabilization module, electrically coupled to the output terminal of the pull-up module, the first output terminal and the second output terminal to thereby stabilize the output terminal of the pull-up module, the first output terminal and the second output terminal to a designated voltage in a particular time.
