Display specification guide
Optical bonding for outdoor LCD displays
Readability depends on both the light a display produces and the light reflected towards the viewer. Optical bonding addresses part of that optical system; it should be considered with the cover glass, brightness control and installation.
Readability depends on both the light a display produces and the light reflected towards the viewer. Optical bonding addresses part of that optical system; it should be considered with the cover glass, brightness control and installation.
What optical bonding does
Optical bonding reduces the air gap between the LCD and protective glass. Reducing internal reflections helps preserve contrast and readability in strong ambient light. It is a different function from selecting a brighter LCD panel or adding an anti-reflection treatment to the outer glass.
Specify the complete viewing arrangement
Tell the supplier where the display will face, whether sunlight is direct, the viewing distance and the expected reflections. Identify any additional window or cover glass between the screen and the viewer. Bonding inside the display does not remove reflections from a separate shop window.
Ask what the brightness figure describes
A specification may quote the LCD panel or the completed assembly. Confirm the measurement basis, front-glass construction and applicable conditions before comparing nit values. For the selected AD Series outdoor LCD range, brightness, optical bonding, anti-reflection protection and automatic brightness control are considered together.
Keep optical and environmental requirements separate
Optical bonding does not establish an IP rating or an impact rating for the installation. The module, enclosure, glass, connectors and mounting need to be assessed against their own requirements. Thermal design must also suit the environment and operating hours.
Include access and validation in the brief
Discuss the replaceable assembly, service access, handling and proposed evaluation. Use representative content at the intended viewing distance and assess daytime and night-time readability. Agree the acceptance criteria for the selected configuration before rollout.
What to include in your brief
- Location, orientation and direct-sun exposure
- Viewing distance, content size and contrast
- Panel versus completed-display brightness
- Cover glass, anti-reflection treatment and any extra window
- Touch, impact protection and environmental requirements
- Temperature, operating hours and service access
