Title:
GATE DRIVER ON ARRAY SHORT CIRCUIT PROTECTION CIRCUIT AND LIQUID CRYSTAL PANEL
Document Type and Number:
WIPO Patent Application WO/2017/024601
Kind Code:
A3
Abstract:
A gate driver on array short circuit protection circuit (100), comprising a power source module (10), a first boost module (20), a feedback module (30), a second boost module (40) and a control module (50), the power source module (10), the first boost module (20), the feedback module (30) and the second boost module (40) being sequentially connected in series, the control module (50) being electrically connected to the first boost module (20), the feedback module (30) and the second boost module (40), the power source module (10) being used for providing a power source voltage, the control module (50) being used for outputting a pulse width modulation signal so as to control the first boost module (20) and the second boost module (40) to convert the power source voltage into a driving voltage, the feedback module (30) being used for obtaining a feedback current and feeding the feedback current back to the control module (50). When the feedback current exceeds a preset current threshold, the control module (50) cuts off the output of the pulse width modulation signal. Also provided is a liquid crystal panel. The gate driver on array short circuit protection circuit (100) implements short circuit protection and increases the stability of the liquid crystal panel.
