Abstract: A rear projection screen for a projection television. The screen includes a pair of plastic sheets, each having lenticular embossments on one side thereof. The embossments are arranged in rows in one direction and alternate embossments are staggered in the opposite direction. The plastic sheets are positioned back-to-back with their lenticular embossed sides facing outwardly. The sheets are oriented with the machine direction of one sheet extending at right angles to the machine direction of the other sheet. The plastic sheets are separated either by glass or can be laminated to a transparent plastic. The lenticular embossments are generally parabolic in shape. Plastic sheets having either approximately 10,000 embossments per square inch or 40,000 lenticular embossments per square inch may be used.
