Abstract:
An image display apparatus, comprising:a plurality of electron emission devices arrayed in a matrix formation; an image forming material provided to form an image by irradiation of electrons emitted from the plurality of electron emission devices; a plurality of row wires and column wires provided to wire the plurality of electron emission devices in the matrix formation; a scanning circuit provided to sequentially supply a scanning signal to the row wires for sequentially selecting the row wires; and a driving signal generator provided to supply driving pulse signals to the plurality of column wires so as to drive electron emission devices connected to the row wire selected by said scanning circuit, wherein the driving pulse signals are corrected by correction values corresponding to a plurality of the column wires to which the driving pulse signals are supplied, to compensate for a voltage drop which depends on an image pattern to be formed, on the row wire selected by said scanning circuit.
