With the vigorous development and progress of the technology era, many electronic devices are constantly being introduced, such as notebook computers, smart phones, tablet computers, digital cameras, e-books, global satellite navigation machines, digital photo frames, etc. Although their panels and touch screens It is scratch-resistant tempered glass itself, but it will still be stained with dirt after a long time of use, and even the friction between dust and hard metal objects (such as keys, coins, etc.) will cause scratches and fine lines on the surface of the tempered glass, resulting in The panel and touch screen are blurred, which affects the quality of viewing and is not beautiful.

Furthermore, today's electronic devices are not only functionally strong or weak, as users demand high-resolution screens and multi-touch screens, the price of screens is relatively more and more expensive, and the external appearance is also considered by users. One important point, so in order to protect the surface of the panel and touch screen from scratches and fine lines, most users will buy protective stickers to stick a film on the surface of the screen, and use the protective stickers to beautify the product, not to leave glue, Convenient for heavy work, basic anti-fouling and scratch-resistant functions, but the current screen protectors on the market tend to leave fingerprints and stains when used, and the overall use effect will be greatly reduced, causing users to use it every once in a while. Repeated wiping with a cleaning cloth is time-consuming and labor-intensive.

However, with the upgrading and advancement of the current display technology, in order to provide users with better visual effects, the screens of electronic devices (such as 7 inches or above) are all moving towards large-scale screens, and light-emitting diode (LED) panels are used to display The technology can achieve high color saturation, high contrast, wide viewing angle, long use time, and more energy-saving functions. However, the light-emitting diode spectrum will emit blue light with a wavelength between 380 and 495nm. Blue light is the energy in visible light. The strongest light, when the user's eyes are watching the screen, because the blue light is not absorbed by the cornea and lens, it can directly reach the retina, causing the eyes to be scattered and difficult to focus due to long-term exposure to blue light, which may cause soreness, fatigue or injury. How to make a protective sticker that is not easy to leave fingerprints and stains, but still maintains good scratch resistance and blue light filtering function is the key to redesign for those in this industry.
