Title:
VIEWING DEVICE
Document Type and Number:
WIPO Patent Application WO1992016075
Kind Code:
A3
Abstract:
A viewing device for receiving video signals and generating corresponding images for viewing comprises a frame or support (10), adapted to be worn on the user's head, for example a frame similar to a spectacle frame. The frame supports in front of each of the wearer's eyes, a pixelated LCD screen (12) and respective optical systems (14) located between the user's eyes and the screens (12) to allow the user to view the images generated as if they were at infinity. A light-transmitting microlens screen (16) may be located in front of each LCD screen to produce an improved subjective viewing impression by "de-pixelating" the image.
