Title:
PROTECTION SYSTEM FOR GOA CIRCUIT AND LIQUID CRYSTAL DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/196330
Kind Code:
A1
Abstract:
A protection system for a GOA circuit and a liquid crystal display panel. A switching circuit (10) is connected to an initial trigger signal (STV), a detection circuit (30), and the GOA circuit; when a low-potential signal is at a low level, the switching circuit (10) is turned on, the GOA circuit accesses the initial trigger signal, and the liquid crystal display panel normally works; and when the low-potential signal is at a high level, the switching circuit (10) is turned off, the GOA circuit does not access the initial trigger signal, and screen burning of the display panel caused by a high-voltage scanning signal is avoided.
