All About Cover Glass

Cover glass is a thin layer of material placed and bonded over a display panel, with a variety of uses. It comes in any number of standard see-through (optically clear) materials, such as glass, polycarbonate, plastic, plexiglass, or acrylic, each with a variety of benifits. Glass is standard for regular TFT LCD screens; AMOLED screens with flexibility may require a flexible plastic instead. Acrylic provides a more shatter-proof experience (but cannot be cleaned by isopropyl alcohol: it will attack the surface and dissolve the polymer chains of the acrylic plastics).

Some of the benefits of adding cover glass onto your flat panel LCD include:

  • Screen protection
    • LCDs have plastic surfaces susceptible to degredation, cracking, and weather! With cover glass added to your panel, you can worry less about your display investments getting damaged through easily-preventable accidents.
    • Vibration and mechanical shock are less effective on displays with cover glass than those without
  • Dust and moisture
    • Condensation and dust can naturally collect on and in your screen over time, rendering it unreadable and consequently useless. By using optically bonded cover glass, you can remove the gap in which dust can form, instead dealing with a cleanable surface.
  • Clarity and visibility
    • In standard LCDs, light has a single plane of refraction between you and the display. During the optical bonding process, internally refected light loss is reduced to create a higher contrast, more easily visible panel.
    • This process also reduces the power needed for backlights, as light produced will be used more efficiently.
    • Sharp, clear images with higher contrast reduce eyestrain as well.
