Patent ID: 7145611

Claim:
A tiled display apparatus, comprising: a plurality of display devices, wherein each display device is subdivided into a plurality of sections with each section separately configured to display a sectional image, each display device including a dead-band region between each pair of adjacent sections; a screen; and a plurality of lens assemblies, wherein each lens assembly is optically coupled to a corresponding one of the sections of each of the display devices to project the sectional image displayed on that section onto the screen, and the plurality of lens assemblies are configured to merge the projected sectional images to form a single tiled image, at least one lens assembly is configured to provide magnification having a magnitude of greater than 1 such that the respective projected sectional image on the screen is larger than the corresponding sectional image on the display device, wherein the lens assemblies provide magnification to merge adjacent projected sectional images together to eliminate the dead-band regions from the tiled image, at least one lens assembly being configured to provide a shift so the respective projected sectional image on the screen is shifted sideways with respect to an axis normal to the corresponding sectional image.
