At the beginning of November 2013, the Japanese authors of the Mitsubishi Electric Corporation Ono, Agari, Mori, Imamura, Miyayama, Nakamura and Nakagawa published their development success of large-area high-performance projected capacitive touchscreens (PCAP) in the 44th edition of the SID Symposium Digest of Technical Papers on pages 215–218. The report points out that double-bearing metal mesh electrodes are used for this purpose.
Optimization of the mesh design
Through the use of highly conductive metal electrodes and simultaneous optimization of the mesh design, both highly sensitive 15-inch self-capacitive touchscreens and 8-inch mutually capacitive touchscreens (mutual-capacitance systems) could be developed. Both are optically connected to LCD modules.
We have compiled further information on the subject of capacitive for you on our website. The complete development report of the large-area high-performance PCAP touchscreens with double-bearing metal mesh electrodes can be purchased at the source mentioned below.
