Abstract

A mobile videophone is capable of transmitting and receiving information in mobile telecommunications systems, particularly cellular radio networks. The videophone includes a display panel on which an image is formed by selectively activating a matrix or array of electrodes; and a video camera located immediately behind the display panel. The matrix or array of electrodes are selectively activated during operating of the video camera to create relatively opaque portions of the display panel so as to create an image on the panel and to maintain a relatively transparent portion of the display panel immediately in front of the camera so as to improve the picking up of images by the camera through the display panel.

What is claimed is:  
     
         1 . A videophone comprising: 
 a display panel on which an image is formed by selectively activating a matrix or array of electrodes; and    a video camera located immediately behind the display panel, wherein the matrix or array of electrodes are selectively activated during operation of the video camera to create relatively opaque portions of the display panel so as to create an image on the display panel and to maintain a relatively transparent portion of the display panel immediately in front of the camera so as to improve the pick up of images by the camera through the display panel.    
     
     
         2 . The videophone of  claim 1 , wherein the relatively transparent portion of the display panel immediately in front of the camera has an image displayed with lesser intensity than other portions of the display panel, during image capture using the camera.  
     
     
         3 . The videophone of  claim 1 , wherein the relatively transparent portion of the display panel located immediately in front of the camera has substantially no image displayed, during image capture using the camera and the display of an image on a remaining portion of the display panel.
