The advantages of the present invention are as follows: 1. The special shapes of the first electrode and the second electrode are arranged to each other to facilitate the finger or conductor touch detection by finger or conductor touch sensing, and the finger or conductor can be accurately touched by the change of the capacitance value. Control the location. 2. In response to the special arrangement pattern of the first electrode and the second electrode, a minimum number of first sensing axes and second sensing axes can be electrically connected to the first electrode and the second electrode to accurately determine the touch of the finger or the conductor. The position further reduces the manufacturing cost of the touch sensing device. Various changes and modifications can be made without departing from the scope and spirit of the invention, and the invention is not limited by the description. Embodiments of the embodiments are given. 13 1354227 BRIEF DESCRIPTION OF THE DRAWINGS The first figure is a schematic view of a first embodiment of a projection type capacitive touch sensing device of the present invention.
