Abstract

Official abstract text for this publication.

Disclosed is a method and apparatus for substantially eliminating the appearance of seams between tiled panels of a display. Non-imaging magnification may be used to substantially eliminate the appearance of seams. Additionally, the appearance of seams between the tiled panels of a display may be substantially eliminated by employing propagation based elimination. The methods disclosed can be used to generate substantially seamless 2D and 3D displays. Additionally, a method and apparatus for achieving substantially uniform panel brightness and color correction may be addressed. The substantially seamless tiled displays may employ specific data formats for use in displaying images on the individual displays which may be tiled together to form a larger, substantially seamless tiled display and may employ other techniques not utilized in known video wall applications. These functions may include an intensity envelope in addition to substantially complying with the Digital Cinema Initiative (“DCI”) security concerns.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for reducing the appearance of seams in a video wall, the method comprising: locating a first panel including at least a first macro pixel proximate to a second panel including at least a second macro pixel, wherein the appearance of a seam is formed by the first panel and the second panel; locating a first waveguide so that light from the first macro pixel is substantially coupled into the first waveguide; locating a second waveguide so that li…
