Abstract:
1. 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 contact point on the resistive element, the contact point is identifiable by two-dimensional coordinates of a location in the area, wherein the resistive element has a total length defined by a first element end and a second element end and a total resistance determinable by a single current path between the first element end and the second first end, only the first element end configured for electrical measurement to determine the two-dimensional coordinates of the contact point, and wherein the first substrate is configured for connection to a power source, such that when the touch event causes the contact at the contact point on the resistive element, the first substrate is configured to provide a voltage to the resistive element at the contact point, and the electrical measurement at the first end is configured to yield a measurement value at least depending on the voltage and the two-dimensional coordinates.
