Huawei Technologies Co., Ltd. yesterday disclosed a patent for "a display panel packaging structure", the public number is &NBSP; CN215008275U.
The patent abstract shows that the application embodiment provides a display panel packaging structure. Among them, the display panel package structure includes:
Interlayer medium layer ILD, and set in the interlayer medium layer above the metal wiring, metal wiring by etching selection ratio of different metal layers composed of multi-layer structure, metal wiring from the display panel effective display area AA extends outward to display panel edge extension;
Metal line set up over the surface of the anode metal layer, anode metal layer used to cover the metal line at least one target metal layer, to avoid anodic etching liquid metal layer of lateral etching on a target, will therefore not be oxygen to form water channel in the aluminum material, put an end to the display panel external water vapor water oxygen channel into the effective display area of display panels, Solved the black spot problem on the display panel.
