Abstract
A two-dimensional capacitive touch sensor having a cover layer of varying thickness arranged on top of its electrode structure. An array of sensing nodes is formed between edge portions of the receiver electrodes and adjacent portions of the transmitter electrodes. To compensate for the varying thickness of the cover layer, the length of the edge portions per sensing node is varied to equalize node sensitivity across the sensor and thus suppress the systematic variation in node sensitivity which would otherwise arise as a result of the varying thickness of the cover layer.
