Patent ID: 7348966

Claim:
A digital resistive-type touch panel, comprising: a first substrate having a first surface; a second substrate having a second surface opposing the first surface; a plurality of first transparent electrodes extending along a first direction on the first surface; a plurality of second transparent electrodes extending along a second direction on the second surface, wherein the second direction is substantially perpendicular to the first direction; a first signal line including: a main line having a predetermined orientation with respect to the first direction; and a plurality of supplementary lines, each supplementary line of the plurality in direct contact with a respective one of the plurality of first transparent electrodes and connected to the main line; a plurality of second signal lines connected to respective ones of the plurality of second transparent electrodes, and first and second power lines respectively connected to opposing ends of the main line, wherein the main line divides a voltage from the first power line into unique voltages in accordance with an internal resistance value of the main line and supplies a respective one of the unique voltages to each of the plurality of the first transparent electrodes via a respective supplemental line of the plurality of supplemental lines, and wherein only one of the second transparent electrodes outputs a voltage corresponding to a location of a contact point between the one of the second transparent electrodes and one of the first transparent electrodes.
