Abstract

The present invention relates to a projecting capacitive touch sensing device, a display panel, and an image display system. The projecting capacitive touch sensing comprises an array of a plurality of sensing units, each sensing unit including: a first electrode made of a sensing material, at least one second electrode made of a sensing material and being disposed around the peripheral of the first electrode, at least one first sensing axis electrically connected to the first electrode, and at least one second sensing axis electrically connected to the second electrodes. The first electrode is quadrangle, while the second electrodes are triangular-shaped. The first electrode and the plurality of second electrodes are arranged to form a rectangular, and a non-sensing area is defined between the first electrode and the second electrodes.
