Abstract:
A touch screen may include pixel elements formed in a display substrate that are spaced from one another by an element spacing. A plurality of capacitance sense pads may be formed from a same conductive transparent layer in an array over the display substrate. Each sense pad may be separated from an adjacent sense pad by a pad spacing aligned within element spacing for a uniform light path for the pixel elements.
