A display includes a stack that includes, from top to bottom: a display layer including an array of spaced pixels and/or spaced subpixels and an array of spaced transmission spaces, wherein each transmission space is defined by a spacing between a subset of the spaced pixels and/or spaced subpixels; a micro-lens array (MLA) layer including an array of micro-lenses, wherein each micro-lens includes a curved surface; and a laser light emitting (LLE) layer including an array of lasers, wherein the curved surfaces of the micro-lenses face the LLE layer.

A display includes a stack that includes, from top to bottom: a display layer including an array of spaced pixels and/or spaced subpixels and an array of spaced transmission spaces, wherein each transmission space is defined by a spacing between a subset of the spaced pixels and/or spaced subpixels; a micro-lens array (MLA) layer including an array of micro-lenses, wherein each micro-lens includes a curved surface in alignment with a corresponding one of the transmission spaces; and a laser light emitting (LLE) layer including an array laser diodes, wherein each laser diode is positioned in alignment with one micro-lens of the MLA layer and the corresponding one of the transmission spaces of the display layer and the curved surfaces of the micro-lenses face the LLE layer.

An illumination device includes a laser source, a conventional diffuser element, and an extender optic with a curved interior surface and a curved exterior surface. Light emitted by the laser source with a given field of illumination (FOI) is received by the conventional diffuser element and outputted towards the interior surface of the extender optic with an increased FOI; the exterior surface of the extender optic then outputs the light received by the interior surface as light with an even greater FOI, usually in the range of 120&#xb0;-185&#xb0;.
