五，Application:
What side light or back-lit usage, there will be two layer use together, from the top to bottom will first be UGR diffuser sheet, then the normal diffuser sheet/film, and the structure will be the UGR diffuser positioned in outer layer with the texture face towards the observer; the diffuser sheet located in the bottom layer which more closer to the LED source.
