Method of producing a panel having an area with light transmissivity

摘要

A method for producing an area of light transmissivity in a generally opaque panel comprises forming an area of reduced thickness in the panel, laser drilling an array of microscopic holes in the area and thereafter filling the holes with a light transmissive material such as a curable polymer. The thinned area may also be filled with a polymer to reinforce the thinned area, and the polymer may be colored to add color to light transmitted through the pattern.
