Description

Blue light protection sticker

The present invention provides a protective device for filtering blue light, in particular, the substrate of the protective sticker is made of a plurality of nano-layered layers through a plurality of first sheets and a plurality of second sheets, so that the protective stickers are attached to the electronic device. On the surface of the screen, a part of the blue light emitted by the screen can be blocked by the laminated substrate to protect the eyes.

According to the vigorous development and progress of the technology era, many electronic devices continue to be introduced, such as smart phones, notebook computers, tablet computers, digital cameras, e-books, global satellite navigation machines or digital photo frames, etc. Although the control screen itself is a scratch-resistant tempered glass, it will still be contaminated with dirt after being used for a long time. Even the dust and metal hard objects (such as keys, coins, etc.) will cause surface scratches and fine lines on the tempered glass. As a result, the panel and the touch screen are blurred, which affects the quality of the viewing and is not beautiful.

Moreover, today's electronic devices are not only functionally strong, but with the high resolution and multi-touch requirements of the screen, the screen price is relatively more and more expensive, and the external aesthetics is also one of the user considerations. Great focus, so in order to protect the panel, touch screen surface is not easy to produce scratches and fine lines, the average user will buy a protective sticker on the surface of the screen for filming, through the protection of the basic anti-fouling and scratch-resistant Wait for treatment to achieve anti-fouling, scratch-resistant effects.

However, with the advancement of display technology today, in order to provide users with better visual effects, the screen of the electronic device is developed toward a large size, and high color saturation can be achieved by using LED display technology. High contrast, wide viewing angle, long use time, and more power saving function. However, the light emitting diode emits blue light with a wavelength between 380 and 495 nm. The blue light is the most energetic light in visible light. When the person's eyes are viewed on the screen, since the blue light is not absorbed by the cornea and the crystal, the direct contact with the retina causes the eyes to contact the blue light for a long time, which may cause the scattered and difficult to focus and feel soreness or injury.

Therefore, some manufacturers have developed a variety of Blu-ray screen protectors for this problem, which can block the impact of some blue light. However, the current Blu-ray screen protectors on the market are mainly divided into two types, the first one. The protective sticker has a substrate (such as polyethylene terephthalate (PET), polyethylene (PE), polymethacrylate (PMMA) or glass, etc.), and the substrate is shaped to filter blue light. The particles are added to the raw material to make the sheet have the function of filtering blue light after forming, and the second is to have a substrate (for example, polyethylene terephthalate (PET), polyethylene (PE). Polymethacrylate (PMMA) or glass, etc., wherein one side of the substrate is attached with a blue light treatment layer, which can filter the blue light treatment layer to achieve the function of filtering blue light, but due to the blue light filtering element The particle or blue light treatment layer itself has high material cost, and the addition of the blue light element particle or the blue light treatment layer layer may easily affect the transmittance. Furthermore, if the blue light treatment layer is attached to one side of the substrate, the protective sticker will also be integrated. Thickened thickness, resulting in the use of the production There are many inconveniences.

Therefore, how to solve the above-mentioned lack of inconvenience and inconvenience is the direction that the relevant industry players in this industry are eager to study and improve.

Therefore, in view of the above-mentioned problems and deficiencies, the creators have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed a protective blue filter.

The main purpose of the present invention is that the substrate of the protective sticker is made of a plurality of nano-layered layers through a plurality of first sheets and a plurality of second sheets, so that the substrate has the effect of blocking part of the blue light, when the protective sticker When the adhesive layer is attached to the surface of the screen of the electronic device, part of the blue light emitted by the screen can be blocked by the substrate to protect the eye, and the laminated substrate can be omitted. The use of filter blue light materials, thereby reducing the cost of materials, so as to achieve the purpose of enhancing market competitiveness.

The secondary purpose of the present invention is that the substrate of the protective sticker has the effect of blocking blue light by using a nano-layered laminate method, which does not require the addition of another blue-filtering layer, thereby reducing the thickness of the formed protective sticker. Thereby achieving the purpose of improving the transparency and the appearance.

Another object of the present invention is that the substrate of the protective sticker is permeable to the bridging agent on the opposite side surfaces, so that the adhesive layer or the functional film layer can be easily attached to the opposite side surfaces of the substrate, thereby facilitating the convenience. The purpose of processing operations.
