Abstract

The invention relates to a near-infrared absorption film filter and a preparation method and application thereof. The near-infrared absorption film filter comprises a transparent base material formed by compounding two layers of transparent films (2 and 4), a compound rubber layer is an adhesive layer (3) which contains a near-infrared absorbent and is 10-30 microns thick, one side of the transparent base material is coated with a scratch-resistant coating (1) which is 3-7 microns thick, the other side of the transparent base material is coated with a pressure-sensitive adhesive layer (5) which is 10-25 microns thick, and the surface of the pressure-sensitive adhesive layer is coated with a release film (6). The near-infrared absorption film filter has a night vision compatible function and a scratch resistant function, and can be easily mounted on the surfaces of such illuminating systems as LCD devices and instrument illuminating devices.

Description

technical field [0001] The invention relates to a near-infrared absorption filter film used for lighting systems such as liquid crystal display devices and instrument lighting and a preparation method thereof. The near-infrared absorption filter film is compatible with night vision imaging systems. Background technique [0002] In the electromagnetic spectrum, the human eye only responds to wavelengths between 380nm and 760nm, which is the color we usually see. In the darker the light, the human eye is less able to distinguish colors and details of objects. If In the dark night, the sense of color is completely lost, and the object object becomes a shadow, blurred. In fact, there is a small amount of natural light in the dark environment, such as moonlight, starlight, atmospheric glow, etc., which are collectively called night sky light. Because they are very weak compared with sunlight, they are also called night lights. In the dark environment at night, in addition to th...
