Flex (Film Lighting Experts) is a US-based developer of films for lighting applications, including films to optimise the performance of films used with front-lit eReader displays.The company said that the company’s technology allows the use of reflective displays which can save power compared to back-lit and OLED displays.
The company claims that because its films are very thin, which minimises image diffusion. The company has done some tests, comparing edge-lit EPD displays to front-light devices using its own films and found that there is significant increase in contrast and Michelson contrast.
