High Sensitive Capacitive Touch Panel with Chain or Mountain-Shaped ITO Electrodes
Keyword(s):
This paper used COMSOL Multiphysics software to simulate and design two kinds of new touch panels with chain and mountain-shaped ITO electrodes, respectively. These two touch panel electrodes were both designed using parallel and vertical capacitance configurations. Compared with traditional common rectangular and diamond-shaped electrodes, it was found in simulation results that parallel and vertical capacitive gains for chain and mountain-shaped electrodes were 30% and 6%, respectively, higher than those for traditional rectangular and diamond-shaped ones. In addition, when the ratio of glass thickness (H) to indium tin oxide (ITO) electrode thickness (h) was larger, the corresponding capacitive gain was smaller.
