PROJECTOR UTILIZING OPAQUE/ TRANSPARENT PROJECTION SCREEN |
摘要 |
A projector assembly having a projecting device and a display screen with a film. The display screen is changeable from between opaque and transparent and the projecting device selectively rear projects an image onto the film such that the image is visible to a user generally from the front side of the screen. When the projector is off or the projection of images is otherwise stopped under predetermined conditions, the screen becomes transparent to provide the user a clear view through the display screen. When the projector is off power is simultaneously applied to the film which becomes transparent. A control device coordinates the application of power with the image projection, such that when the projected image is removed the screen becomes clear to see through the display screen, and when the projected image returns the screen becomes opaque for viewing the image. |
