Abstract:
An apparatus performs proximity touch sensing, and includes a shield layer, an electrostatic capacity touch panel disposed with a specific distance above the shield layer, and a proximity touch controller for sensing a non-contact touch by supplying a voltage to the electrostatic capacity touch panel and the shield layer and thus by forming a first capacitance.
