Abstract

The present invention discloses a touch panel, of which the effective touch area is non-rectangular. The touch panel comprises a touch sensor array system covering the effective touch area. The touch sensor array system comprises a plurality of touch sensor units which the shape is hexagon, and the touch sensor units are arranged in a honeycomb. The present invention also discloses a touch screen. Through the above mentioned manner, the present invention enables the touch sensor unit to cover the non-rectangular effective touch area better, and assures the consistency of the touch weight.
