Abstract:
A visual display having microperforations, backlighting and contrasting surface finishes is disclosed. The visual display includes an opaque base object having a front surface and a plurality of microperforations therethrough from the front surface to a back surface. Each microperforation has a diameter of about 100 microns or less, and numerous microperforations are arranged into an overall pattern, such as a logo, text or advertisement. A light source placed proximate to the back surface passes light through the microperforations to be visible at the front surface, such that the overall pattern can be visibly perceived when the light source is turned on. A contrasting surface finish formed on the front surface includes at least two visibly distinguishable shades, with one shade covering at least a portion of the front surface defined by the overall pattern, such that the overall pattern can be seen when the light source is turned off.
