Abstract

An integrated electromagnetic type input flat panel display apparatus is disclosed. The integrated electromagnetic type input flat panel display apparatus comprises a display panel, a control unit and a signal processing unit. The display panel has a display unit and an electromagnetic sensor unit, wherein the display unit and the electromagnetic sensor unit are integrated in to a substrate of the display panel. The signal processing unit receives and processes the signals from the electromagnetic sensor unit.
