LED Lighting using our Front Light Guide Technology
Front Light Guides provide very uniform Front Lighting on various kinds of displays including reflective LCDs, E-readers and Printed Materials without affecting the readability of the material.
Front Light Guide Benefits
- Much Lower Power
- Very Uniform Lighting
- Very Thin Profile
- Very Low Cost
Front Lighting allows low power devices to be lit with up to 10X less power than required by traditional backlit LCD displays. It also allows reflective displays to be useful in a wider range of applications. Front Light Guides add less than 1mm of thickness to the display. Our Light Guides use Nano Imprinting Technology to provide a low cost solution to Front Lighting of reflective displays.
Light Guide Description
Light travels from the LED array on the left into the Front Light Guide Plate (FLGP) in blue. Internal reflection optical characteristics keep the light within the FLGP. Only the local Micro-Lenses re-direct the light down to the Reflective Display. Light, then is reflected by the LCD out towards the viewer. The density or fill factor of the Micro-Lenses is varied across the display to control the amount of light which is redirected. This allows the FLGP to provide uniform lighting across the whole display area.
Micro Lens Arrays
The Micro-Lenses play a very important role in providing very high uniformity and efficiency compared to other Light Guide designs. In Front Lighting Solutions, the Micro-Lenses offer unsurpassed clarity for see through applications. We use Semiconductor Technology to create the Micro-Lens structures.
