HIGH PERFORMANCE SEAMLESS LIGHT EMITTING DIODE ILLUMINATED DISPLAY

摘要

A display illumination module for the illumination of a rear-projection screen is provided in which a first array of light sources is positioned adjacent to a first face of an optical modulating array layer for modulating the transmission of light emitted by the first array light sources. The first array light sources emit light within a defined angular range, and the optical modulating array layer is positioned relative to the first array of light sources so that light from adjacent light sources does not overlap at the optical modulating array layer. A second array of light sources is positioned adjacent to a second side of the optical modulation array layer and is arranged such that light from the second array of light sources does not pass through said optical modulation array layer and said second array of light sources does not substantially block light from the first array of light sources passing through the optical modulating array layer. One or more display modules may be incorporated into a display system that includes a rear projection screen that is spatially offset from the optical modulating array layer so that light emitted from adjacent light sources in either the first or the second array of light sources overlaps on the screen.

1. A display illumination module comprising:
a first array of light sources, wherein each light source of said first array of light sources is configured to emit light within a defined angular range; an optical modulating array layer positioned adjacent to said first array of light sources for modulating a transmission of light emitted from said first light sources, wherein said optical modulating array layer is positioned relative to said first array of light sources so that light emitted from a given light source in said first array of light sources does not substantially overlap with light emitted from another light source from said first array of light sources within said optical modulating array layer; and a second array of light sources positioned on an opposite side of said optical modulating array layer relative to said first array of light sources, and positioned to emit light in a same general direction as the modulated light from said first array of light sources.
