Crystal Display Systems are now able to offer Optical Bonding.
This new and innovative technology has been designed for optimum viewing in bright ambient light .
Optical bonding is the use of an optical-grade adhesive to glue a glass to the top surface of a display. The main goal of optical bonding is to improve the display performance under outdoor environments. This method eliminates the air gap between the cover glass and the display. Moreover, anti-reflective coating is often used in optical bonding glass. The real problem for display readability in outdoor environments is not the display’s brightness but its contrast. Contrast means the ratio of the white level to the black level; in other words, the contrast ratio of display means the difference of light intensity between the brightness white pixel and the darkest black pixel. The main purpose of optical bonding is to increase the display’s contrast ratio by reducing the amount of reflected ambient light.
- Increased ruggedness: Bonding a sheet of glass on top of the display increases the ruggedness of the display.
- Optimum visuals in bright ambient light
- Improved durability: A bonded display is better able to resist scratches, fluids, stains and dirt.
- Condensation: The elimination of an air gap between the cover glass and the display means that moisture cannot penetrate and cause fogging on display’s surface.
- Extended temperature range and EMI filtering: The temperature range of the display can be extended by incorporating ITO heaters on the cover glass; EMI filters can be added via the same mechanism.
