Patent ID: 8390599

Claim:
A touch panel comprising: a first substrate, and a second substrate spaced from the first substrate leaving a gap between the first substrate and the second substrate, wherein the second substrate comprises a resistive element arranged in a meandering shape in an area, such that when a touch event occurs on the touch panel causing a contact between the first substrate and the second substrate at a first contact point on the resistive element, the first contact point is identifiable by two-dimensional coordinates of a location in the area, wherein the resistive element comprises a first element end and a second element end, the first element end configured for electrical measurement, and wherein the first substrate is configured for connection to a power source, such that when the touch event causes the contact at the first contact point on the resistive element, the first substrate is configured to provide a voltage to the resistive element at the first contact point, and the electrical measurement at the first element end is configured to yield a first measurement value at least depending on the voltage and the two-dimensional coordinates, and wherein the second element end is also configured for electrical measurement, such that when the touch event also causes the contact between the first substrate and the second substrate additionally at a second contact point on the resistive element, the second contact point is identifiable by different two-dimensional coordinates of the area, and the electrical measurement at the second element end is configured to yield a second measurement value.
