1. A device comprising:
a laptop computer having a full-size QWERTY keyboard including: a plurality of keycaps disposed in first and second rows of keycaps, the first row of keycaps being horizontally offset from the second row of keycaps such that the keycaps of the first row of keycaps partially overlap the keycaps of the second row of keycaps, each keycap having end portions with linear and parallel edges where end portions of each keycap are horizontally offset from end portions of each other keycap, each keycap configured to actuate a different switch of the computing device, each keycap including a metal material and having an upper surface and a lower surface, the upper surface of each keycap configured to be viewed by a user while operating the computing device and defining a plurality of openings in each keycap, the openings in the upper surface of each keycap being patterned in a shape of a single alphanumeric character, the lower surface of each keycap defining a plurality of openings in each keycap, each keycap defining a plurality of microscopic passageways extending from the openings defined by the upper surface of each keycap through each keycap to the openings defined by the lower surface of each keycap; and at least one light source configured to emit light through each of the microscopic passageways of each keycap from the lower surface side of the microscopic passageways to the upper surface side of the microscopic passageways, the light source including a single light guide film configured to guide light from the light source to each keycap. |
