Abstract
A touch panel includes a substrate, a sensing array, a plurality of first connection lines and at least two button sensing pads. The substrate has an active region and a peripheral region disposed on at least one side of the active region. The sensing array is disposed in the active region, which includes a plurality of first sensing electrode series disposed in the active region along a first direction and a plurality of second sensing electrode series disposed in the active region along a second direction. The first and second sensing electrode series intersect and form a plurality of sensing units. The first connection lines are disposed in the peripheral region and electrically connected to the first sensing electrode series respectively. The at least two button sensing pads are disposed in the peripheral region, and electrically connected to at least two first connection lines respectively to form a virtual button.
