Abstract

The invention relates to a method for reducing air bubbles generated by laminating waterproof protective films and a broken-code liquid crystal device, belonging to the technical field of segment-code liquid crystal products. The method includes the following steps, step S1: tearing off the release film on the surface of the electronic paper of the product, and performing plasma cleaning; step S2: attaching the waterproof protective film to the surface of the electronic paper after plasma cleaning; step S3: cleaning the product defoaming. The product processed by the invention greatly reduces the generation of bubbles in the bonding of the waterproof protective film while ensuring the waterproof performance, and improves the product quality. The segment code liquid crystal device prepared by adopting the above method of reducing air bubbles by laminating the waterproof protective film is lighter and thinner than the liquid crystal device using glue waterproof, the product quality is improved, and it is not easy to generate air bubbles.

Description

technical field [0001] The invention relates to the technical field of segment code liquid crystal products, in particular to a method for reducing air bubbles generated by laminating a waterproof protective film and a segment code liquid crystal device processed by the method. Background technique [0002] Compared with dot-matrix liquid crystals, segment-code liquid crystals have more free arrangement shapes, and segment-code liquid crystal products have simple structures and low production costs, and have broad application prospects in daily life and industrial production. [0003] With the improvement of material living standards, people's requirements for electronic products are getting higher and higher, which promotes the development of segment code LCD products towards the trend of thinner and smarter. Glue is used for waterproofing in the existing waterproof process of the segment code liquid crystal display, but the glue has a certain thickness, which is not conduc...
