An apparatus for providing a multicolored illuminator for displays is disclosed. In one embodiment, the apparatus comprises a first sheet comprising a plurality of columnar illuminators stacked side by side, and a plurality of colored light sources placed along an edge of the first sheet. The plurality of columnar illuminators diffuse light generated by the plurality of colored light sources. The light emanates in a predetermined pattern.
摘要:
An apparatus and method for a light source are disclosed. The apparatus comprises a light guide including light extracting features and at least one light source placed near an end of the light guide. Light from the light source gets deflected by the light extracting features and emanates in a predetermined pattern along a surface of the light guide. The light guide has different thicknesses in different parts.
