<p>A contactless touch panel comprises a first transparent substrate, a plurality of planar (or miniaturized) microsensors dispersedly arranged on a surface of the first transparent substrate, a second transparent substrate stacked on the first transparent substrate to cover the microsensors, and a detecting element electrically connected to the microsensors. Thus, when a touching object approaches (does not touch) the touch panel, the microsensors sense the touching object via an electric field or a magnetic field and generate sensing signals sent to the detecting element according to changes in the electric field or the magnetic field and their strength. The detecting element determines a position of the touching object above the touch panel to achieve the purpose of non-contact control.</p> |
