ADJUSTABLE SHIELD ELECTRODE ARRANGEMENT FOR CAPACITIVE TOUCH SENSOR ARRAY

摘要

An apparatus (2) comprising: a plurality of distinct capacitive sensor electrodes (6) distributed over a sensing area (8); conductive traces (10) connected to respective ones of the plurality of distinct capacitive sensor electrodes (6); one or more first shield electrode portions (21), positioned on a first side (35) of the sensing area (8) to overlap, in the sensing area (8), at least some of the conductive traces (10), and one or more second shield electrode portions (22), positioned on the first side (35) of the sensing area (8) to overlap, in the sensing area (8), at least some of the capacitive sensor electrodes (6).
