Abstract
A capacitive touch slider array comprises a first conductive trace associated with a first sensing node. The first conductive trace includes a first conductive line and a plurality of first conductive fingers extending from the first conductive line. The plurality of first conductive fingers have lengths that increase from a first end of the capacitive touch slider array to a second end of the capacitive touch slider array. A second conductive trace associated with a second sensing node includes a second conductive line and a plurality of second conductive fingers extending from the second conductive line. The plurality of second conductive fingers have lengths that increase from the second end of the capacitive touch slider array to the first end of the capacitive touch slider array.
