A Design Method of Symmetrical Double Lenticular Screen for Rear Projection Large 3D Displays

There are rear projection large 3D displays that allow you to view 3D TV motion pictures without special 3D glasses. The screen employs lenticular plates whereby both the projection side and viewing side have the same double symmetrical shape. A double symmetrical design calls for two lenticular plates having approximately the same shape fabricated to enable a stable 3-dimensional view. When designing the lenticular shape, however, it is difficult to satisfy light absorption characteristics on both the projection and viewing sides while maintaining the geometric relationship of both the projection and viewing sides. This paper describes a design method of symmetrical double lenticular screen for rear projection large 3D displays, and also describes a description of the result of applying the method to a 70-inch HDTV 3D display using a symmetrical double lenticular screen. As a result, we were able to obtain a quality 3D effect that requires no special 3D glasses, and by using a lenticular screen, we are able to view a crisp, high definition 3D image.
