Backlights now feature sunlight-visibility layer
OMC have announced that its ProfiLED coloured LED backlights are available with a proprietary active backing layer that enables them to be viewed in much brighter ambient lighting conditions. This is especially relevant for makers of portable instrumentation which is used outdoors.
Complementing a standard product range which numbers over 250 different sizes, OMC can turn around bespoke-shaped ProfiLED backlights is as little as five working days with little or no setup costs. The company claims that this is often the only viable option for small to medium volume (fewer than 10,000 pieces) requirements. The high-visibility option – termed Royale Reflector – incorporates an active backing layer in the backlight’s back reflector, which enhances contrast in high ambient lighting conditions, ensuring that the display remains visible.
Explains William Heath, Commercial Director, OMC: “A standard reflector is of limited use in brighter areas as the ambient light simply washes out the display. In our Royale Reflector series we build a special backing layer into the backlight’s reflector, which filters out ambient wavelengths that are destructive to the contrast of the display, while at the same time reflecting forwards wavelengths that add constructively to the LED output. In that way, users can see the display much more clearly.”
The same technology can be used to reduce the power required, as the LED emitters need to do less work to adequately illuminate the display. The technology is available in all of OMC’s red, yellow, orange and green ProfiLED backlights.
