Abstract
A double-layer mutual capacitive touch panel includes a first conductive layer and a second conductive layer. The first conductive layer includes multiple electrodes arranged in an array. In each column of the array, the electrodes at the ((N*M)−1)th row are mutually electrically connected to form a first electrodes series, and the electrodes at the (N*M)th row are mutually electrically connected to form a second electrode series, where N is a positive integer greater than or equal to 2 and M is a positive integer greater than or equal to 1. The second conductive layer includes M mutually insulated electrode strip groups sequentially arranged along a column direction of the array. Each electrode strip group includes N electrode strips mutually electrically connected, and each electrode strip of each electrode strip group extends along a row direction of the array and overlaps the electrodes of the corresponding row.
