Problems solved by technology

During the test, it is necessary to apply a high voltage to the VDD&VSS wiring to make the PLN film layer easy to burn and carbonize. As the burn increases, the conduction between the VDD&VSS power supply wiring will cause abnormal display on the display panel.

Abstract

The invention provides a display panel and a display device. The display panel comprises an array substrate and a packaging cover plate. A first power line and a second power line are arranged on thesame layer of the array substrate. The second power line is disconnected by an opening, a first connecting line penetrates through the opening to be connected with the first power line, a second connecting line is connected with the second power line, and the second power lines on the two sides of the opening are electrically connected through jumper wires arranged on the packaging cover plate. According to the scheme, the jumper wires are arranged on the packaging cover plate to connect the second power lines at the two ends of the opening, and the problem that the flat layer is prone to carbonization due to heat caused by the fact that the jumper wires are arranged below the second power lines is solved. And particularly, the jumper wire material with low resistivity is adopted, so thatthe heat productivity is better reduced, and the abnormal display problem caused by short circuit is avoided.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the advancement of technology and consumers' requirements for display screens, the size of AMOLED products is getting larger and larger. Correspondingly, the number of light-emitting pixels on the display panel is increasing, and the current required for all pixels of the entire panel to emit light is also greater. [0003] The display panel is provided with VDD&VSS power supply wiring for supplying current to the EL light-emitting device, and the test electrodes are respectively connected to the VDD&VSS power supply wiring. During the test, it is necessary to apply a high voltage to the VDD&VSS wiring to make the PLN film layer easy to burn and carbonize. As the burn increases, the conduction between the VDD&VSS power supply wiring will cause abnormal display on the display panel. Contents...
