ABSTRACT:
A screen assembly for a rear projection television set, including a frame portion extending about a viewing portion thereof, the viewing portion defining a lenticular screen. The frame and viewing portions may be formed as one piece, for example from injection molded plastic. The screen assembly includes a fastener for mounting the lenticular screen to a projection television set over an opening therein, and preferably for slidably mounting the lenticular screen in a focal plane thereof. The fastener may include slots extending horizontally along upper and lower regions of the frame portion for receiving slide rails attached to the television set. A set of projection tubes and a mirror mounted in the television set project a viewable image onto the lenticular screen. The lenticular screen is slidable along the focal plane between a securable closed position and an open position which provides access into the television set, for example, to focus the image on the lenticular screen without removing the screen assembly from the focal plane.
