Description

Double-sided antistatic LR film, assembly and display device

Technical Field

The invention relates to a multilayer composite material technology, in particular to a double-sided antistatic LR film, a component and display equipment.

Background

In recent years, TAC (triacetyl cellulose film) and PET (polyethylene terephthalate) substrates have been increasingly widely and deeply used for electronic display panels. The insulating properties of TAC and PET themselves tend to generate and accumulate static charges during contact and rubbing. The existence of a certain amount of static charge can cause static impact on TAC and PET electronic products, damage the performance of the electronic products and cause safety accidents. Meanwhile, the electrostatic charge on the surface easily adsorbs dust, and has a certain influence on the appearance of the high-transmittance film.

The prior art is used for doping conductive substances and adding antistatic agents in the using process of plastic film products. Since conductive materials such as metal powder, conductive carbon black, and metal oxide are expensive to use and have high requirements for coating equipment, antistatic agents have become a main means for improving the antistatic performance of film materials. Currently, antistatic agents commonly used mainly include cationic antistatic agents, anionic antistatic agents, amphoteric antistatic agents and nonionic antistatic agents. The commonly used ionic antistatic agent achieves the antistatic purpose by absorbing environmental moisture and reducing the surface resistivity of the material, so the dependence on the environmental humidity is larger. Obviously, the higher the ambient humidity, the stronger the water absorption of the antistatic agent molecules, and the more remarkable the antistatic property. Meanwhile, the environmental humidity is low, and the antistatic performance of the coating is weakened, which shows that the ionic antistatic agent molecules are greatly influenced by the environment and the antistatic performance is unstable.

The anti-reflection layer can be formed by three methods, including vacuum evaporation, wet coating and magnetron sputtering coating. Among them, the uniformity of vacuum evaporation coating is poor, the adhesion of the coating is poor, the repeatability is poor, and it is difficult to obtain a film with a crystalline structure. The magnetron sputtering process has low coating efficiency, high energy consumption, high requirements on equipment and process conditions and high cost, and needs laminated coating.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
