The application range of liquid crystal display is very wide, the use of the process will inevitably have the loss of the liquid crystal display, through some measures to protect the liquid crystal display, not only can improve the durability of the liquid crystal display, but also facilitate the later maintenance of the product.
Protective glass
Often referred to as hardened glass or chemically strengthened glass, this glass can be used to replace the regular ITO glass on the display, or it can be used as a separate protective layer above the display.
OCA optical adhesive bonding
Although protective glass can play a protective role, but if you want the product to be more durable, or with protection, such as UV, moisture and dust, choose OCA bonding will be more appropriate.
OCA optical adhesive is one of the important raw materials of touch screen. The optical acrylic adhesive is made of no substrate, and then a layer of release film is affixed to the bottom layer, which is a double-sided adhesive tape without matrix material. It has the advantages of high light transmittance, high adhesion, water resistance, high temperature resistance and UV resistance.
Using optical glue to fill the air gap between the TFT LCD and the top surface of the display reduces light refraction (from the LCD backlight and external light), thereby improving the readability of the TFT display. In addition to the optical benefits, it can also improve the durability and touch accuracy of the touch screen, and prevent fog and dew.
Protective cover
Use an alternative protective cover material, such as polycarbonate or polyethylene, which is less expensive but not as durable. It is usually used for non-handheld, low-priced products used in harsh environments. The thickness of the cover is between 0.4 mm and 6 mm, and the protective cover is installed on the surface of the LCD, and the cover can withstand the impact instead of the display.
