Title:
SHIFT REGISTER, LEVEL-TRANSMISSION GATE DRIVE CIRCUIT, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2016/095267
Kind Code:
A1
Abstract:
Provided are a shift register, a level-transmission gate drive circuit, and a display panel, which are capable of reducing the size of a transistor, preventing the deterioration of the transistor, and increasing circuit output capability. The shift register comprises a down-transmission module (110), an output module (120), a first pull-down maintenance module (130), a second pull-down maintenance module (140), a first pull-down module (150), and a second pull-down module (160); the down-transmission module (110) is used for receiving a level-transmission signal (ST(n-1), CST(n-1)) of an upper-level shift register; the output module (120) is used for outputting a level-transmission signal (ST(n), CST(n)) and a scan signal (G(n)); the first pull-down maintenance module (130), second pull-down maintenance module (140), first pull-down module (150), and second pull-down module (160) are used for keeping the output signal at a low electric potential after the output module (120) outputs the scan signal (G(n)).
