Title:
SHIFT REGISTER UNIT, DRIVING METHOD THEREFOR, ARRAY SUBSTRATE GATE ELECTRODE DRIVER DEVICE, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2016/161727
Kind Code:
A1
Abstract:
Provided are a shift register unit, a driving method, an array substrate gate electrode driver device, and a display panel, for use in reducing the duty cycle of a thin-film transistor connected at a pull-down node, thus preventing aging of the thin-film transistor, and increasing the service life of the thin-film transistor. The shift register unit comprises: an input module (201), an output module (202), a reset module (203), a functional module (204), a first pull-down module (205), and a second pull-down module (206). The first pull-down module (205) is configured to: provide, in response to the high potential of a first square wave signal (VLL 1) and a high potential signal of a first pull-down node (PD 1), the low potential of a second square signal (VLL 2) to a pull-up node (PU) and an output end (OUTPUT). The second pull-down module (206) is configured to: provide, in response to the high potential of the second square wave signal (VLL 2) and a high potential signal of a second pull-down node (PD 2), the low potential of the first square wave signal (VLL 1) to the pull-up node (PU) and the output end (OUTPUT).
