  • Touch panel for display device integrated with front light unit
    Patent number: 6654006
    Abstract: A touch panel for a display device is structured such that one resistive layer of a pair of resistive layers disposed opposing each other across a plurality of insulating dot spacers is laid on a flat hard glass plate which is integrally combined with a light conductive plate of a front light unit sandwiching elastic spacers. The total thickness measuring when a touch panel is attached to a display device, is reduced, and the accuracy of the information on the position, the display quality and the durability are improved.
