I liken the haze on the backside of the crystal to the haze you get on the inside of your car after some time of not cleaning the inside windshield. It is not noticeable until you are driving into the sun. In the car I think different materials are breaking down and releasing "stuff" in the environment of the car.


It could also have to with heat build up between the solar panels and the lcd causing extra particles to adhere to the backside of the crystal.
