Problems solved by technology

However, in the prior art, some film structures are composed of a large number of film layers, resulting in an excessive thickness of the film structure.
In this way, when the film layer structure is attached to the screen, it will have a bad influence on the appearance of the electronic product
In addition, although some film structures have a high transmittance to visible light in the wavelength range of 400 nm to 700 nm, they have a low barrier rate to light in the wavelength range of 380 nm to 420 nm, which cannot fully protect the eyes of electronic product users.

Embodiment Construction

[0050] figure 1 It is a schematic diagram of the film layer structure of an embodiment of the present invention. Please refer to figure 1 , the film layer structure 100 of this embodiment includes a coating layer 102 , a substrate 104 and an adhesive layer 106 stacked in sequence in the direction d. In this embodiment, the adhesive layer 106 includes a colloid 106a and a filter compound 106b dispersed in the colloid 106a. The filter compound 106b is used to filter components of light within a specific wavelength range, wherein the specific wavelength range is 380 nm to 420 nm. In this embodiment, the film layer structure 100 may optionally include a release film 108 . The adhesive layer 106 is disposed between the substrate 104 and the release film 108 . When the user intends to use the film structure 100, the release film 108 can be removed, and the adhesive layer 106 can be brought into contact with the object (such as the screen of an electronic product or the user's sp...

Abstract

A film structure including a substrate, a coating layer, and an adhesive layer is provided. The coating layer and the adhesive layer are respectively disposed on two opposite surfaces of the substrate. The adhesive layer includes a chemical composition for filtering a light ray. The adhesive layer cuts off the light ray in a specific wavelength range when the light ray passes through the adhesive layer. A cut-off rate of the light ray in a wavelength range of 380 nm to 420 nm is greater than 80%.

Description

technical field [0001] The present invention relates to a film structure, and in particular to a film structure capable of protecting eyes. Background technique [0002] Existing electronic products usually use high-brightness light-emitting diodes as backlight sources in order to make the screens have high brightness. However, the light emitted by LEDs contains components in the wavelength range of 380 microns to 420 microns. Light with a wavelength range of 380 microns to 420 microns can penetrate the lens and reach the macula of the retina, causing the decline of retinal pigment epithelial cells, resulting in the death of photosensitive cells, and finally causing macular degeneration, resulting in decreased vision and even loss of vision. [0003] In order to reduce the damage to the eyes caused by light in the wavelength range of 380 microns to 420 microns, someone has developed a film structure for sticking on the screen of electronic products. When the film structure...
