Abstract

The invention provides a display panel and a method for improving a display panel Newton ring. The light inside the display panel spreads to the outside of the display panel through at least one substrate, an optically polymerized organic material is coated on the predetermined position of an upper surface or a lower surface of any of the substrates, a refractive index changes when the optically polymerized organic material is irradiated by laser light, when the Newton ring occurs, laser irradiation of a region where a Newton's ring appears on the display panel is carried out through utilizinga laser device, the molecular structure of the optically polymerized organic material is made to change, the refractive index changes, the interference condition of the Newton ring is destroyed, a Newton ring phenomenon is ameliorated, and frame quality of the display device is improved.

Description

technical field [0001] The invention relates to the field of flat panel display, in particular to a display panel and a method for improving the Newton ring of the display panel. Background technique [0002] Newton's rings are a common defect in the flat panel display industry. The main reason for Newton's rings is that the cover glass bends, and the parallel incident light and reflected light interfere with each other, resulting in alternate bright and dark concentric rings, which affect the image quality of the final display device. A common solution in the prior art is to adjust the height of the encapsulant and the pillars in the box so that the array substrate and the cover glass are more parallel. [0003] For example, in the manufacturing process of OLED (Organic Light-Emitting Diode, organic light-emitting diode) display, the array substrate and the transparent substrate are usually manufactured separately first, and then the glass frit (Frit) coated on the transpar...
