Display panel and display device

Abstract

The invention provides a display panel and a display device. The display panel comprises a cover plate, wherein an adhesive layer is arranged on the periphery of the peripheral area of the cover plate; the base plate and the cover plate are oppositely arranged, the base plate is provided with a display area and a peripheral area, and the base plate comprises a substrate; the test wires are located on at least one side of the peripheral area; the first reflection metal film layer is located on the periphery of the peripheral area and located on the side, close to the display area, of the test wire; the second reflective metal film layer is located between the test wire and the first reflective metal film layer in the horizontal distribution direction and is not electrically connected with the first reflective metal film layer; the test wire, the first reflective metal film layer and the second reflective metal film layer are arranged on one side, close to the cover plate, of the substrate. Therefore, the first reflective metal film layer and the second reflective metal film layer are not electrically connected, the situation that molten metal overflows and is in short circuit with the test wiring in the laser sintering process of the reflective metal film layers can be avoided, and the product yield is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a display panel and a display device. Background technique [0002] OLED devices (such as AMOLED (Active-matrix organic light emitting diode, active matrix organic light emitting diodes or active matrix organic light emitting diodes) devices are self-luminous devices, relying on driving their own organic light emitting materials to emit light, with high brightness, high performance. It has the advantages of low power consumption and high resolution. With the iterative update of new technologies and new products, new products have higher requirements for narrowing the frame, and the realization of narrow frame, a basic rule in design, is to meet the process In the case of equipment, the spacing is continuously compressed for each position. [0003] In the current product design, in order to meet the narrow frame requirements of the product, the distance between the meta...

AI Technical Summary

Problems solved by technology

[0003] In the current product design, in order to meet the narrow border requirements of the product, the distance between the metal film layer that provides the VSS signal and the box test line closest to the metal film layer is only about 7 microns, which is very small. , there may be printing offset of Frit glue (encapsulation adhesive layer on the cover plate) and laser sintering energy fluctuations. The distance between the test line and the nearest box is very small. After the metal melts and overflows, it is easy to short-circuit with the test line of the box, resulting in abnormal signals, resulting in abnormal product display and other defects.
