Size of screen might be an issue though since you are lighting from the perimeters
I actually mentioned this idea in my earlier post, but maybe it was not clear that the LightWedge is a sidelight. The size of the screen is a problem, as you said. When they cover a small area, they can be thin causing only a little distortion, as is the case with a PDA. As the coverage area gets larger, you need something more substantial to diffuse the light, which is why the lightwedge is not very thin, leading to problems Harry mentioned above.
