| description | A projection display apparatus comprises a compact CRT, a projecting lens for projecting an enlarged image of the CRT, a Fresnel lens having a converging effect, a lenticular sheet as a diffusing plate. An image that has been enlarged by the projecting lens and passed through the lenticular Fresnel lens is formed on the lenticular sheet. The apparatus further comprises a displacing mechanism for displacing the Fresnel lens, and a display mechanism for displaying information related to the direction and extent of displacement of the Fresnel lens displaced by the displacing mechanism. |
