  • System and apparatus for keyboard illumination
    Patent number: 7717607
    Abstract: A portable computing device, including a keyboard illumination device and system may include a light emitter housing incorporated into the hinge element of a portable computing device. The light emitter housing may include an aperture and a light emitter and may be configured to illuminate a keyboard while keeping the source of the emitted light hidden from the user and others who may be in the vicinity of the portable computing device. The light emitter, which illuminates the keyboard, may be driven by a different light source than the light source that illuminates a display panel of the portable computing device. It follows that the brightness of the light emitter may be adjusted without having any effect on the brightness of the display panel.
