Title: SHIFT REGISTER CIRCUIT AND DISPLAY PANEL APPLIED THERETO
Abstract:
A shift register circuit and a display panel applied thereto, the shift register circuit (13) comprising multi-stage shift registers, and each shift register comprising: a first switch (T10), a control terminal (101a) of the first switch (T10) being electrically coupled to a first node (Q(n)), a first terminal (101b) of the first switch (T10) being electrically coupled to a frequency signal (HCK), and a second terminal (101c) of the first switch (T10) being electrically coupled to an output pulse signal (G(n)); a second switch (T20), a control terminal (201a) of the second switch (T20) being electrically coupled to a control signal (F(n-1)), a first terminal (201b) of the second switch (T20) being electrically coupled to the control signal (F(n-1)), and a second terminal (201c) of the second switch (T20) being electrically coupled to the first node (Q(n)); a third switch (T30), a control terminal (301a) of the third switch (T30) being electrically coupled to the first node (Q(n)), a first terminal (301b) of the third switch (T30) being electrically coupled to the frequency signal (HCK), and a second terminal (301c) of the third switch (T30) being electrically coupled to a control signal (F(n)); and a fourth switch (T40), a control terminal (401a) of the fourth switch (T40) being electrically coupled to the first node (Q(n)), a first terminal (401b) of the fourth switch (T40) being electrically coupled to the frequency signal (HCK), and a second terminal (401c) of the fourth switch (T40) being electrically coupled to generate a feedback signal (Fb(n)).
