Description

Technical Field

[0001] The utility model relates to the field of brightness enhancement films, in particular to a brightness enhancement film with an anti-blue light structure. Background Art

[0002] Brightness-enhancing film with an anti-blue light structure is a new type of material, mainly used in the field of display technology, such as liquid crystal displays (LCDs) and organic light-emitting diode (OLED) screens. The design goal of this brightness-enhancing film is to reduce the damage of blue light to the human eye while improving display brightness and color performance. The general process of adding an anti-blue light structure to the brightness-enhancing film is to apply the anti-blue light material on the substrate by spraying or brushing. Specific dyes or coatings are often added to the anti-blue light material. These dyes can absorb blue light in specific bands.

[0003] In certain environments, due to direct sunlight or light, the brightness enhancement film may cause glare, making the image on the screen look blurred and affecting the viewing experience. The original intention of the design of the brightness enhancement film is to enhance brightness and visual effects, but direct light may cause reflections and glare, thereby offsetting the effect of the brightness enhancement film. Prolonged exposure to direct light may cause the brightness enhancement film and the display to overheat. Overheating may cause the film material to deform or age, affecting the brightness enhancement effect. For this reason, we have proposed a brightness enhancement film with an anti-blue light structure. Utility Model Content

The silicone 8 is coated on the anti-blue light coating 3. The silicone 8 is a transparent material. As an adhesive, silicone usually performs well under high temperature and humidity and can provide strong adhesion.

[0027] Furthermore, the curved layer includes a curved film 4, a flat film 7, an outer frame 13 and a protrusion 14. The side of the silicone 8 facing away from the anti-blue light coating 3 is adhesively connected to the flat film 7, and the other side of the flat film 7 is fixedly connected to the protrusion 14.

The flat film 7 is bonded to the silicone 8, and the thermal insulation filler 11 in a molten state is filled in the outer frame 13. When the curved film 4 is closed, the thermal insulation filler 11 solidifies and connects the curved film 4 and the flat film 7. The curved layer is a transparent thin film material. The curved film can effectively reduce the influence of direct light. Through its special design, the curved film can reduce light reflection, reduce dizziness and light interference. In order to save space, the thermal insulation filler 11 is directly filled in the cavity of the curved layer.

[0028] Furthermore, a heat-insulating coating 9 is provided on the side of the brightness-enhancing film 1 facing away from the anti-blue light coating 3. The heat-insulating coating 9 is applied on the brightness-enhancing film 1. The heat-insulating coating 9 and the heat-insulating filler 11 are transparent heat-insulating coatings, which are heat-insulating and transparent materials. They are mainly made of indium tin oxide and have good light transmittance and heat-insulating properties. This coating can effectively reflect solar thermal radiation.

[0029] Furthermore, the heat-insulating coating 9 is glued to the pressure-sensitive adhesive 10 on one side facing away from the brightening film 1, and the other side of the pressure-sensitive adhesive 10 is glued to four protective films 2. The four protective films 2 are evenly distributed and completely fit the pressure-sensitive adhesive 10. A hand-tear piece 5 is fixedly connected to one side of the protective film 2. The position of the hand-tear piece 5 corresponds to the four corners of the pressure-sensitive adhesive 10. The material of the protective film 2 is polyester film.

The protective film 2 is coated on the outer surfaces of the brightness enhancing film 1, the anti-blue light coating 3 and the thermal insulation material that are in contact with the outside world, completely wrapping them. The waterproof coating 6 has a waterproof effect on the brightness enhancing film. The waterproof coating is a special coating designed to prevent water and moisture from penetrating into the surface of an object. The waterproof coating 6 is a silicone coating that can be used for various materials, providing good waterproof performance and high temperature resistance, and is suitable for electronic products and building materials.

[0031] Working principle: The brightness enhancement film 1 has a prism side coated with an anti-blue light coating 3, and the anti-blue light coating 3 is glued to the curved layer through silicone 8. The side of the brightness enhancement film 1 that is attached to the device is coated with a heat insulation coating 9, and the other side of the heat insulation coating 9 is glued to the pressure-sensitive adhesive 10, and the other side of the pressure-sensitive adhesive 10 is glued to the protective film 2. When using the brightness enhancement film, the user pinches the tear-off piece 5 to tear off the protective film 2 and then glues the brightness enhancement film to the device. The prism structure of the brightness enhancement film 1 has a brightness enhancement effect. The micro-prism structure in the brightness enhancement film 1 can effectively refract light and reduce direct light from the external environment. The anti-blue light coating 3 is a compound with special optical properties that can be embedded in a polymer or resin to reduce the light transmittance within a specific wavelength range (i.e., blue light), thereby reducing the impact of blue light on the eyes.
