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.

What is claimed is: 
     
         1 . 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.   
     
     
         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.
