Abstract
A mutual-capacitance touch sensing device including a touch panel, a plurality of driving electrodes and a plurality of sensing electrodes is provided. The touch panel is substantially parallel to a reference plane. The driving and sensing electrodes are arranged to from a matrix including a plurality of sensing units. Each of the sensing units is associated with at least one driving electrode and at least one sensing electrode. A gap is formed between the at least one driving electrode and the at least one sensing electrodes. A projection length of the gap on the reference plane is longer than a total length of two diagonal lines in each of the sensing units.
