Light from an LCD is reflected through the gap and then the screen’s outer glass to form the display. Light is interrupted and bent as it goes through the screen’s gap and glass, and part of it is reflected, which is what we call refraction.
This refraction across the layers reduces the final image’s readability and overall brightness. With optical bonding, you eliminate interruptions and light reflections. The image is brighter because more light reaches the screen’s surface.
The same thing as above holds true when an external light source, such as the sun, hits the screen. The space between the glass and LCD allows for refraction, reflecting external light to the viewer as glare.
Light travels through the connected layers and is absorbed into the screen. Optical bonding is crucial for any devices that people will be using out in the sunlight.
Creates a More Durable Screen
One of the biggest benefits of optical bonding is that the addition of the resin layer improves the durability of the screen. That extra resin layer helps absorb shock, which decreases the risk of the screen shattering when dropped. This is an added benefit for people who use various devices in high-risk environments.
Prevents Condensation Buildup
Placing a resin layer between the glass and LCD makes it impossible for dust and moisture to accumulate between the two layers. Dust and wetness aren’t major issues for screens in normal conditions due to manufacturing quality.
Condensation between the two layers can be an issue in settings with significant temperature variations or high humidity. Condensation occurs when moisture from the air gap enters the screen. Closing the space physically prevents this issue. Optical bonding is suitable for both outdoor and indoor applications where temperature control is difficult.
