Technology briefing

Portable 3C electronic products are easy to be damaged by falling. The damaged parts include the body itself and the panel glass, so some protective measures are usually taken on the body. There are many options for protecting the products, and the use of transparent protective films is more common. Since the panels of LCD and OLED displays are all glass based, they are the most fragile part of electronic products, which is the components need most protection. By the way, the up-to-date portable device employed electronic pen to write input directly on the screen. Therefore, a paper like protection hard coat on the glass then be an innovative and necessary material   

on the surface of the cover glass. 

The protection of the display panel usually uses PET as the base material which is with good optical properties, acid and alkali resistance, and explosion-proof. After coated with hard coat layer, the surface hardness could be enhanced to be more than 3H to resist the scratch. An micro-structured layer with anti-glare function also could applied with the coat to provide a higher optical performance to enhance the visibility of display on the electronics devices.

In present time, a personal devices always employed an electronic pen for writing or drawing on the display directly. However, the display panel is quite smooth which lose the writing experience on a paper.  A paper like protection film is with a surface structure made of a special recipe, which not only provides a hard coating protection and anti-glare function to the display, but also can offer users a familiar writing or drawing experience, which is similar to that of a traditional pen and paper.
