Patent ID: 8717312

Claim:
A touch sensing device, comprising: a substrate having a plurality of first sensing regions and a plurality of second sensing regions arranged in a matrix, wherein each first sensing region is surrounded by four second sensing regions and vice versa; a plurality of first touch electrodes, alternately arranged along a first direction, each of the first touch electrodes including a plurality of first sensing pads, each of the first sensing pads having at least one first sensing portion disposed in a corresponding first sensing region and at least one first complementary portion disposed in a corresponding second sensing region; and a plurality of second touch electrodes, alternately arranged along a second direction substantially perpendicular to the first direction to form a sensing matrix, each of the second touch electrodes including a plurality of second sensing pads, each of the second sensing pads having at least one second sensing portion disposed in a corresponding second sensing region and at least one second complementary portion disposed in a corresponding first sensing region, such that each first sensing pad is surrounded by four second sensing pads and vice versa; and each first sensing pad is entangled with four neighboring second sensing pads surrounding the first sensing pad along with diagonal directions of the first and second directions, and at least two neighboring first sensing pads along with at least one of the first and second directions and vice versa.
