For low profile LCD pagers the problem is to develop a very low profiled diffuser that allows the end user to perceive an evenly lit LCD display. Commonly the diffusers are optic clear plastics with a light source entry point, usually a flat plane. This poses a problem in that, a) it does not optimize light entry, and b) the end user generally will end up with darker and lighter zones.
