Title: SHIFT REGISTER CIRCUIT AND DISPLAY PANEL USING SAME
Abstract:
A shift register circuit and a display panel using same. The shift register circuit comprises multiple stages of shift registers. Each shift register (300) comprises: a first switch (T10), a control end (T13) of the first switch (T10) being electrically coupled to a first node (P1), a first end (T11) of the first switch (T10) being electrically coupled to a first frequency signal (CLK'), and a second end (T12) of the first switch (T10) being electrically coupled to a gate signal (G(N)) of the present stage; a second switch (T20), a control end (T23) of the second switch (T20) being electrically coupled to the first node (P1), a first end (T21) of the second switch (T20) being electrically coupled to a second frequency signal (CLK), and a second end (T22) of the second switch (T20) being electrically coupled to a frame signal (STV(N+1)) of the next stage; and a third switch (T30), a control end (T33) of the third switch (T30) being electrically coupled to a frame signal (STV(N)) of the present stage, and a second end (T32) of the third switch (T30) being electrically coupled to the first node (P1).
