Technique for forming protective coating on electronic ink screen

Abstract

The invention discloses a technique for forming a protective coating on an electronic ink screen. The technique comprises the following steps that firstly, a connecting finger of the electronic ink screen is coated and covered; secondly, baking and moisture dispelling are conducted for removing moisture on the electronic ink screen, and the electronic ink screen is baked for 2-3 h at the temperature of 50-60 DEG C; thirdly, a coating object at the connecting finger of the electronic ink screen is clamped by a clamping buckle, the clamping buckle is hung on a metal rack, and the metal rack is put into a coating machine; and fourthly, material feeding is conducted for gas phase deposition coating. The technique is simple, the thin film coating which is uniform in thickness, dense, free of needle holes, transparent and unstressed, does not contain addition agents, does not damage a workpiece and has excellent electric insulativity and protective property can be formed on the surface of the electronic ink screen, the protective effects of moisture prevention, mold prevention, corrosion prevention, water prevention, salt-spray prevention, static prevention, or oxidation prevention and the like are achieved, and the service life of the electronic ink screen is prolonged.

Problems solved by technology

The electronic ink screen is an important part of the electronic shelf label. During the production process of the electronic ink screen, the waterproof performance of the film used will be different. At the same time, the sealing effect may not be ideal during the production process, resulting in the unusability in long-term humidity. , oil pollution or other harsh environments

[0003] The existing electronic ink screen has no protective coating on the surface, or because the process is not perfect, the protective coating coating is not reasonable enough, and the protection functions such as moisture-proof, mildew-proof, anti-corrosion, waterproof, anti-salt spray, anti-static or anti-oxidation, etc. Not good enough, resulting in poor electronic shelf label display performance
