Is it the backlighting that is the problem?

There is a category of LCD that is front illuminated or just uses ambient light (sunlight, room lighting) to make the screen readable. These LCD are often found in displays that must be used outdoors. Perhaps there is an outdoor oriented LCD tablet that could fit your requirements?
