Abstract

The invention discloses an anti-blue-ray display screen and a preparation method thereof. The anti-blue-ray display screen comprises a display screen body and is characterized in that the display screen body comprises a tempered glass cover plate, an optical adhesive layer for blocking blue rays and ITO glass which are arranged from top to bottom, a heavy release layer is arranged on the optical adhesive layer for blocking the blue rays, and a light release layer is arranged on the lower surface of the optical adhesive layer for blocking the blue rays. The tempered glass cover plate and the ITO glass are bonded through the blue-light-blocking optical adhesive layer, the blue-light-blocking optical adhesive layer can effectively block blue light and ultraviolet light, and the tempered glasscover plate and the ITO glass have the good physical and chemical properties of high light transmittance, high bonding strength, low shrinkage rate and the like, excellent weather resistance and excellent shock resistance and explosion resistance; and the safety, the reliability, the durability and the attractiveness of the whole display screen are greatly improved.

Description

technical field [0001] The invention relates to the technical field of optical adhesive films, in particular to an anti-blue light display screen and a preparation method thereof. Background technique [0002] With the increasing application of touch screens, LCD screens and naked-eye 3D screens, new requirements are put forward for the raw materials used for full lamination, such as high light transmission, adaptability to large sizes, easy degassing, and high weather resistance. At present, the main applications are OCA and LOCA optical glue. OCA Optical Adhesive is a double-sided bonding tape without a matrix material. It is the most commonly used adhesive for bonding touch screens and LCD panels, but it is difficult to bond and requires high precision, especially for larger sizes. Touch screens and LCD screens (such as 7 inches or more) are very difficult to fit, easy to produce air bubbles, and cannot be reworked. LOCA is a liquid optical adhesive developed on the bas...
