ABSTRACT:
The method for the fabrication of a curved back projection screen includes coating the screen before forming a sheet into the proper curvature. In one embodiment the sheet includes lenticulations to improve the perceived luminous intensity thereof. Through this method a back projection screen is provided that overcomes the manufacturing difficulties associated with previously known methods.
