Display apparatus

Abstract

A display apparatus is provided which can display different text/image information depending on the viewing angle and the viewer, display a high reality three-dimensional image viewable from any direction and realize stereoscopic viewing without glasses or the like. The display apparatus includes a display unit having a view angle-limiting filter on its surface, a rotary mechanism to rotate the display unit and a control unit which implements control so that when the display unit, rotated by the rotary mechanism, is faced to each of plural directions, the display unit displays a different text/image content associated with the direction.

1 . A display apparatus, comprising: 
 a screen having a view angle-limiting filter on a surface thereof;    a rotary mechanism which rotates the screen; and    an electronic projector which, when the screen being rotated by the rotary mechanism is faced to each of a plurality of rotation directions, projects each of mutually different projection images including information or image corresponding to each of the plurality of rotation directions to the screen.    
   
   
       2 . The display apparatus according to  claim 1 , wherein the electronic projector is comprised by arranging with plural around the screen so as to project each of the mutually different projection images from each of the plurality of rotation directions to the screen.  
   
   
       3 . The display apparatus according to  claim 1 , wherein the mutually different projection images form a three-dimensional image.  
   
   
       4 . The display apparatus according to  claim 2 , wherein the mutually different projection images form a three-dimensional image.  
   
   
       5 . The display apparatus according to  claim 1 , further comprising a acquiring unit which acquires the projection images to be projected from the electronic projector and stores the projection images in a memory unit; 
 wherein the acquiring unit reads out the projection images stored in the memory unit so as to supply the projection images to the electronic projector.    
   
   
       6 . The display apparatus according to  claim 2 , further comprising each of image pickup devices being arranged by combining with each of the electronic projectors so that each of the image pickup devices pickups each of images of an object provided in stead of the screen at a location being provided the screen on the rotary mechanism.
