Abstract: A touch panel able to recognize user commands whether from a finger actually touching or from a non-touching finger floating above the panel includes a substrate; a plurality of touch electrodes, a driver electrically connected to each touch electrode, and connection lines on the substrate. The touch electrodes are divided into a plurality of touch units, each touch unit including at least two touch electrodes. The driver outputs touch driving signals to drive each of the touch electrodes and can recognize more than one level of current as a result of actual touches or as a result of virtual or floating “touches” on the touch electrodes. Each connection line is electrically connected to the driver and one touch electrode. The driver is further configured to autonomously control the touch panel to work in a first touch mode or a second touch mode without manual switching by a user.
