Abstract

An OLED panel provided by the present application includes a substrate, and a plurality of signal lines and at least one spare line which are disposed on the substrate, wherein the signal lines and the spare line are located in different layers; the spare line is equipped with a plurality of preset connection points; the projection of any of the signal lines on the substrate coincides with the projection of two preset connection points on the substrate; and when any of the signal lines is in an open circuit, the signal line in the open circuit is electrically connected to the spare line through the preset connection point in order that the signal line in the open circuit works normally through the spare line. The at least one spare line is disposed on the substrate. When any signal line isin the open circuit, the signal line in the open circuit can work normally through the spare line, thereby achieving a purpose of improving the display quality of the OLED display panel, improving the product yield of the OLED display panel, and also increasing the shipment rate of the OLED display panels.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display panel. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode), as a current-type light-emitting device, is widely used because of its advantages such as self-illumination, rich colors, fast response speed, wide viewing angle, light weight, and flexible display. focus on. [0003] For a general OLED display panel, since the distance between the signal lines is small, there is a risk of disconnection of the signal lines during the manufacturing process. When the signal line is disconnected, it will affect the display quality of the OLED display panel, thereby reducing the yield rate of the product and resulting in a decline in the shipment rate of the OLED display panel. Contents of the invention [0004] The present application provides an OLED display panel, which can not only improve the display quality of t...
