| Popis: | All glass, lenticular lens array, light guide substrates were fabricated in a single mask and etch procedure enabling 1D local light-confinement from an edge-injected LED array. Lenticular structures of sufficient resolution (width & pitch: 100–200 µm) were etched along the length of the thin-slab glass surface, at depths in the range 40–90 µm using an etchant optimized for the alkali-borosilicate composition (Corning Iris Glass). These structures’ aspect ratio (W/H 80%) along the lenticular corridors. The all-glass and high-transmission nature of the iris glass composition enabled higher brightness operation and yielded negligible color-shift. |
