Optical glue, method for manufacturing optical glue, and display device

Abstract

Embodiments of the present invention provide an optical glue, a method for manufacturing the optical glue, and a display device. The surface of the optical glue is provided with a through hole. The optical glue manufacturing method comprises: sandwiching the optical glue between two mask plates, wherein the openings of the two mask plates correspond to each other, and the optical glue is laser-cutthrough the openings of the mask plate in correspondence with the areas on the optical glue to be formed with the through holes; as the through holes are arranged on the optical glue, air bubbles generated in the process of curved touch screen packaging can be discharged, and can also accommodate deformation folds produced when the surfaces are fitted. At the same time, the optical adhesive of the embodiment of the invention has the function of cushioning stress and preventing the generation of cracks. The optical adhesive of the embodiment of the invention can solve the problem that air bubbles are difficult to eliminate and wrinkles exist when the curved surface of the curved touch screen is bonded in the encapsulation process, and can improve the product performance and prolong the service life of the product.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an optical glue, a method for making the optical glue, and a display device. Background technique [0002] With the increasing development of flexible display technology, the curved touch screen has a beautiful appearance and has more advantages in terms of gloss and wear resistance; at the same time, the curved design of the curved touch screen matches the arc of the palm, which is more in line with ergonomic requirements and is very popular among users. . However, the following problems exist in the packaging process of the curved touch screen: it is difficult to remove air bubbles when the curved surface is bonded, and wrinkles are generated, which subsequently leads to cracks, and eventually causes water vapor to penetrate into the visible area, resulting in black spots, or light leakage, which is serious. Destroy product performance and shorten the service life of the p...
