The optical bonding process involves adhering a film or liquid adhesive between the display and a layer of plastic, glass or a touchscreen. This enhances the contrast ratio and display readability in bright sunlight.
The properties of the adhesive deliver a number of optical and physical benefits to a display’s performance, including:
- Direct sunlight readability – 500-600 cd (candela)
- Improved contrast and brightness
- Improved impact resistance
- Prevention of moisture ingress
All of these factors make this an ideal display technology for use in harsh environments or outdoor applications.
The displays are available for TFT sizes ranging from 2.4” to 10.1”, and connectivity is provided via an FFC interface.
