Abstract

A first display screen 1 is a conventional television screen, being used to display a first (background) image. A second display screen 3 is transparent, and is placed in front of, and is spaced apart from, the first screen by a spacer or substrate 2. The second, transparent display being used to display a second (foreground) image, which is different from the first (background) image. The separate, synchronised content, displayed on the two overlapping screens means causes a parallax effect to the viewer (Fig. 3), resulting in two distinct perspective stereoscopic images, which cause the viewer to experience a 3D effect of the program content. Glasses are not required to detect this effect.

Description

DESCRIPTION
A normal tv display screen 1 (drawing 1/3) is used for background images and a transparent display screen 3 ( drawing 1/3) is used for foreground images. The two display screens are held a short gap apart by a substrate 2 (drawing 1/3) . Background screen 1 (drawing 2/3) , substrate 2 (drawing 2/3) and transparent foreground screen 3 (drawing 2/3) shows the completed unit.
Content can be sent to the two screens separately but in sync with each other so that a foreground image 4 (drawing 3/3) on the transparent screen 2 (drawing 3/3) background image 5 (drawing 3/3) on the background screen 1 (drawing 3/3) can be viewed as a merged complete image. The eyes 3 (drawing 3/3) see slightly different images called a stereo pair of images, the basic requirement for any 3D system. No glasses are required to see the 3D images. Images can be moved frame by frame between screens towards or away from the viewer.

Claims (1)

  1. CLAIMSClaim 1 A transparent screen is placed a short distance in front of a normal screen joined by a substrate or other means. The background is shown on the normal screen while foreground images are shown on the transparent screen. When viewed together a stereo pair of images is created, slightly different views for each eye. The stereo pair of images is the basic requirement for any 3D image, and will be seen by the viewer without the need for glasses.Claim 2 Original content can be converted to 3D by separating background and foreground images with an edit on the system described in claim 1. Claim 3 Moving images frame by frame between the two screens will allow the viewer to detect images moving towards and away from them in the system described in claim 1.
