1. An electronic device comprising:
- a housing having a first surface and a second surface and having at least a one hole formed through the housing between the first surface and the second surface, wherein the at least one hole is less than 0.1 mm in diameter at the first surface and wherein the cross-sectional area of the at least one hole increases as the hole extends from the first surface to the second surface; and
a light sensitive receptor positioned adjacent the second surface proximate the at least one hole.

Abstract
An invisible, light-transmissive display system with a light resistant material is provided. Substantially invisible, tapered, light-transmissive holes are penetrated in a lighttransmissive pattern through at least a portion of the light resistant material using a laser beam having a focal width less than the smallest diameter of the tapered holes.

15. An electronic device comprising:
-
a housing configured to hold a keyboard, wherein the keyboard includes a plurality of keys, at least one of the plurality of keys having a first surface and a second surface and having at a plurality of holes formed between the first surface and the second surface to create a pattern of holes, wherein each of the plurality of holes is less than 0.1 mm in diameter at the first surface and wherein the cross-sectional area of each of the plurality of holes increases as the hole extends from the first surface to the second surface; and a light source positioned adjacent the second surface proximate the pattern of holes, such that the pattern of holes is substantially invisible when the light source is off and such that the light source illuminates the pattern of holes when the light source is on. - View Dependent Claims (16, 17, 18)
