Document Type and Number:
WIPO Patent Application WO/2020/182063
Kind Code:
A1
Abstract:
Disclosed in the present application are an apparatus (400) and a method for preventing static electricity in a display panel, and a display apparatus (100), comprising: a sensing sub-circuit (401) connected to a drive chip of the display panel; a discharging circuit (402) connected to the sensing sub-circuit (401) and the drive chip (301); a current driver sub-circuit (403) connected to the sensing sub-circuit (401), the discharging circuit (402), and a release end (404); and the release end (404), which is connected to the discharging circuit (402) and which connects to a ground wire of a driver circuit board. The sensing sub-circuit (401) senses static electricity, the current driver sub-circuit (403) outputs and detects current in the sensing sub-circuit (401), causing the discharging circuit (402) to switch on or off, and the static electricity is released to the release end by means of the discharging circuit (402) and the current driver sub-circuit (403).
