A combined backlighting panel, position determination system, and display for use in pen-driven computer systems. There is a panel of a transparent material divided into a plurality of illumination areas. Each of the illumination areas comprises a lensing structure on the bottom surface of the panel for directing entering light towards the top surface of the panel over the associated illumination area. A plurality of light-emitting diodes are disposed to direct light into the lensing structure of respective ones of the plurality of illumination areas.
