Transparent display with diffuser-backed microtextured illuminating device and method of manufacture therefor |
摘要 |
<p>A substantially planar illuminating device, a visual display and a method of manufacture therefor. The illuminating device includes: (1) a light source (210) and (2) a transparent substrate (220) having a pair of substantially parallel major surfaces (230,240) and an entry point (250) for accepting light from the light source, the substrate functioning as a guide for the light, one of the pair of surfaces textured with a plurality of microelements (260) for scattering the light from the substrate, the microelements having a side wall with a side wall area, the side wall area being a function of a distance of the microelements from the entry point to enhance a uniformity of the scattering of the light over an area of the pair of surfaces. <IMAGE></p> |
