2d/3d display and method for forming 3d image

Abstract

A display capable of providing 2D and/or 3D images. The display comprises a liquid crystal display device and a self-emissive display device. The self-emissive display device is disposed on the rear of the liquid crystal display device, in which the liquid crystal display device provides a first image and the self-emissive display device a second image and a backlight source. One of the first and second images comprises a parallax barrier pattern for forming a three-dimensional (3D) image, and the other is a 2D image.

1 . A method for forming a 3D image, comprising: 
 forming a 2D image by a liquid crystal display device; and    forming an image with a parallax barrier pattern behind the 2D image by a self-emissive display device, such that a 3D image is observed by a viewer from the liquid crystal display device side by transforming the 2D image through the parallax barrier pattern.    
     
     
         2 . The method as claimed in  claim 1 , wherein the parallax barrier pattern comprises a plurality of dark strips parallel or perpendicular to each other.  
     
     
         3 . The method as claimed in  claim 2 , further comprising adjusting the width of each dark strip and the space therebetween according to a perpendicular distance of the viewer to the center of the liquid crystal display device.  
     
     
         4 . The method as claimed in  claim 2 , further comprising adjusting the shift of the dark strips in a perpendicular direction according to a parallel distance of the viewer to the center of the liquid crystal display device.  
     
     
         5 . The method as claimed in  claim 1 , wherein the parallax barrier pattern fully or partially overlaps the 2D image.  
     
     
         6 . The method as claimed in  claim 1 , wherein the self-emissive display device comprises an organic light-emitting device or a plasma display device.  
     
     
         7 . A method for forming a 3D image, comprising: 
 forming a 2D image by a self-emissive display device; and    forming an image with a parallax barrier pattern in front of the 2D image by a liquid crystal display device, such that a 3D image is observed by a viewer from the liquid crystal display device side by transferring the 2D image through the parallax barrier pattern.    
     
     
         8 . The method as claimed in  claim 7 , wherein the parallax barrier pattern comprises a plurality of dark strips parallel or perpendicular to each other.  
     
     
         9 . The method as claimed in  claim 8 , further comprising adjusting the width of each dark strip and the space therebetween according to a perpendicular distance of the viewer to the center of the liquid crystal display device.  
     
     
         10 . The method as claimed in  claim 8 , further comprising adjusting the shift of the dark strips in a perpendicular direction according to a parallel distance of the viewer to the center of the liquid crystal display device.  
     
     
         11 . The method as claimed in  claim 7 , wherein the parallax barrier pattern fully or partially overlaps the 2D image.  
     
     
         12 . The method as claimed in  claim 7 , wherein the self-emissive display device comprises an organic light-emitting device or a plasma display device.  
     
     
         13 . A method for forming a 3D image, comprising: 
 forming a first 2D image by a self-emissive display device; and    forming a second 2D image by a liquid crystal display device opposing to the self-emissive display device;    wherein one of the first and second 2D images comprises a parallax barrier pattern, such that a 3D image is observed by a viewer from the liquid crystal display device side by the parallax barrier pattern.
