Abstract
A touch sensor includes a resistive layer on a substrate and electrodes on the resistive layer. The electrodes and portions of the resistive layer between the electrodes form series resistor chains disposed at peripheral regions of the touch sensor and surrounding a touch region of the touch sensor. The electrodes are formed by forming a conductive layer on the resistive layer in a thin-film deposition process, followed by patterning the conductive layer into the electrodes. A sheet resistivity of the resistive layer is between about 200Ω and about 800Ω. A sheet resistivity of the conductive layer is between about 0.03Ω and about 0.2Ω. A ratio of the sheet resistivity of the resistive layer to the sheet resistivity of the conductive layer is between about 2,500 and about 10,000.
