Title:
WIRING STRUCTURE OF PIXEL DRIVING CIRCUIT, DISPLAY PANEL, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/192365
Kind Code:
A1
Abstract:
Provided are a wiring structure of a pixel driving circuit, a display panel, and a display device. The pixel driving circuit comprises: a first switch element (T1), wherein a control terminal is coupled to a scan signal line (Gate), a first terminal is coupled to a data signal line (Data), and a second terminal is coupled to a first node (N1); and a driving transistor (DTFT), wherein a control terminal is coupled to a second node (N2), a first terminal is coupled to a power signal line (VDD), and a second terminal is coupled to a third node (N3); the power signal line comprises a first power signal line (VDD1) in the same direction as the data signal line, and a first distance between the data signal line and the control terminal of the driving transistor is greater than a second distance between the first power signal line and the control terminal of the driving transistor. The driving circuit may improve the problem of crosstalk caused by the inconsistency of gate-source voltage jumps of the driving transistor.
