Document Type and Number:
WIPO Patent Application WO/2018/205322
Kind Code:
A1
Abstract:
A shift element temporary storage circuit, a waveform generation method thereof, and a display panel applying same. The shift element temporary storage circuit comprises: a multi-stage shift register (300) including: a first switch (T10), the 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 an input pulse signal (ST), a first end (201b) of the second switch (T20) being electrically coupled to the input end pulse signal (ST), and a second end (201c) of the second switch (T20) being electrically coupled to the first node (P1(n)); a third switch (T30), a control end (301a) of the third switch (T30) being electrically coupled to a second node (P2(n)), a first end (301b) of the third switch (T30) being electrically coupled to the output pulse signal (Gn), and a second end (301c) of the third switch (T30) being electrically coupled to a low preset potential (Vs); and a fourth switch (T40), a control end (401a) of the fourth switch (T40) being electrically coupled to the second node (P2(n)), a first end (401b) of the fourth switch (T40) being electrically coupled to the first node (P1(n)), and a second end (401c) of the fourth switch (T40) being electrically coupled to the low preset potential (Vss). The distance (L) between the internal channels of the first end (401b) and the second end (401c) of the fourth switch (T40) is increased and is designed as two channels (L2, L3).
