Abstract
A method and apparatus for backlighting a handwriting input area for a portable computing device. The portable computing device includes a display area for displaying alphanumeric data and other images. Underneath the display area is a digitizer input area by which users enter handwritten information into the portable computing device. The portable computing device contains handwriting recognition software which converts the handwritten information into alphanumeric data. Both the display area and the digitizer input area are both backlit to facilitate usage in poor lighting conditions.
