Title:
GOA CIRCUIT AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2020/215553
Kind Code:
A1
Abstract:
A GOA circuit (300) and a display panel (600). According to the GOA circuit (300), by means of the improved design of a pull-down holding circuit unit (350), a pull-down holding circuit unit (350) can still work normally even if the threshold voltage deviations of a fifty-first switching transistor (T51) and a fifty-third switching transistor (T53) in the pull-down holding circuit unit (350) are large because the fifty-first switching transistor (T51) and the fifty-third switching transistor (T53) are be affected by a large current stress, so that a scan level signal (Qn) maintains a normal potential to ensure that a scan signal (Gn) outputs a normal waveform.
