Title:
STATIC ELECTRICITY DISCHARGE PROTECTION CIRCUIT AND DISPLAY DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/051924
Kind Code:
A1
Abstract:
Disclosed are a static electricity discharge protection circuit (300) and a display device using same. The static electricity discharge protection circuit (300) comprises a first switch (T10), a control end (T13) of the first switch (T10) being electrically coupled to a first node (A), a first end (T12) of the first switch (T10) being electrically coupled to a grounding node (GND), and a second end (T11) of the first switch (T10) being electrically coupled to a signal input node (P); a capacitor (C) electrically coupled between the first node (A) and the signal input node (P); a second switch (T20), a control end (T23) and a first end (T22) of the second switch (T20) being electrically coupled to a low level line (VGL), and a second end (T21) of the second switch (T20) being electrically coupled to the signal input node (P); and a third switch (T30), a control end (T33) of the third switch (T30) being electrically coupled to a high level line (VGH), a first end (T31) of the third switch (T30) being electrically coupled to the first node (A), and a second end (T32) of the third switch (T30) being electrically coupled to the low level line (VGL). By opening the first switch (T10) and the third switch (T30), static electricity is discharged to the grounding node (GND) and a first level line (VGL).
