Document Type and Number:
WIPO Patent Application WO/2018/201517
Kind Code:
A1
Abstract:
A shift register circuit and a display panel using same. The shift register circuit (300) comprises a plurality of levels of shift registers, each shift register comprising: a first switch (T10), a control end (101a) of the first switch (T10) being electrically coupled to a first node (P1(n)), a first end (101b) of the first switch (T10) being electrically coupled to a frequency signal (CK), and a second end (101c) of the first switch (T10) being electrically coupled to an output pulse signal (Gn); a second switch (T20), a control end (201a) of the second switch (T20) being electrically coupled to the first node (P1(n)), a first end (201b) of the second switch (T20) being electrically coupled to the frequency signal (CK), and a second end (201c) of the second switch (T20) being electrically coupled to a control signal (Fn); a third switch (T30), a control end (301a) of the third switch (T30) being electrically coupled to a control signal (F(n-1)), a first end (301b) of the third switch (T30) being electrically coupled to a first direct current signal (VDD_LC1), and a second end (302c) of the third switch (T30) being electrically coupled to the first node (P1(n)); and a fourth switch (T40), a control end (401a) of the fourth switch (T40) being electrically coupled to the control signal (F(n-1)), a first end (401b) of the fourth switch (T40) being electrically coupled to a second direct current signal (VDD_LC2), and a second end (402c) of the fourth switch (T40) being electrically coupled to the first node (P1(n)).
