Abstract:
1. A control method of an image display apparatus which comprises a display panel in which a plurality of display devices are arranged in matrix with a plurality of column wires and a plurality of row wires, the method comprising the steps of: outputting a selection electric potential to a row wire to be driven; and generating a modulated pulse based on image data and outputting the modulated pulse to the column wires, wherein in the step of generating and outputting the modulated pulse, supposing that n is an integer of at least 1, t (1) in case of outputting a modulated pulse corresponding to gradation value n, a control is executed to cause the modulated pulse to rise in a slope shape so that the pulse height value reaches h (2) in case of outputting a modulated pulse corresponding to gradation value n+k, a control is executed to cause the modulated pulse to rise in a slope shape so that the pulse height value reaches h
