Portable display
In one embodiment, the modular display includes aggregates of individual panel tiles arranged between two large plastic sheets. The footprint of the large plastic sheet sandwich becomes the dimension of the display screen. The tilettes are phosphor emission panels with a full complement of emittable pixels. By separating the tilettes from the final full dimension sheet, the tilettes can be manufactured in transportable sizes and the outer full dimension sheets can be rolled for easy transport to the final install location.
1. An apparatus comprising:
a plurality of image emission modules each comprising:
multiple phosphor regions, wherein at least one phosphor region emits light of a first color when excited and at least one phosphor region emits light of a second color when excited;
a plurality of light engines, wherein each light engine generates one or more excitation beams to excite the multiple phosphor regions of a corresponding image emission module and the multiple phosphor regions of one or more image emission modules adjacent to the corresponding image emission module;
a visible light transparent support structure comprising:
a first visible light transparent sheet wherein the plurality of image emission modules are placed upon the first visible light transparent sheet; and
a dichroic filter layer positioned in contact with the first visible light transparent sheet.
