A simple but effective new film has been introduced and demonstrated by Chicago-based firm, FLEx Lighting, ideal for use in E-Readers.
The film can work with as little as one LED, allowing it to remain energy-efficient whilst it functions as a guide for light, enabling it to travel uniformly across the surface of a screen, resulting in a soft glow as it lights the surface below it. It's vital to the quality and reflectivity of E-Reader panels that any surface layers remain as thin and close to the panel as possible and FLEx's edge lighting system manages this with a film only 50 microns thick, that can be laminated directly onto a panel. The company claims that the film will work happily with monochrome or full colour RGB displays.
This technology would be perfectly suited for future generation E-Readers such as the Amazon Kindle, where currently a generally costly case with an LED light is required to use the device in the dark or in dimly-lit rooms. You can see an example of the new film in action in the YouTube video below.
