Patent ID: 6947018

Claim:
An image display apparatus, comprising: an image display member having a plurality of light-emitting portions arranged in a two-dimensional arrangement; a plurality of electron emitting devices arranged on a substrate, in correspondence with each of the plurality of light-emitting portions, for causing emission of light from each of the plurality of light-emitting portions; and a circuit that adjusts at least one of a plurality of input signals each of which corresponds with one of the plurality of electron emitting devices, wherein adjustment by said circuit includes an adjustment in which a light emitting brightness caused by an electron emitting device in a first position and a light emitting brightness caused by an electron emitting device in a second position different from the first position are different from each other, in a case where an input signal corresponding with an electron emitting device in the first position designates the same brightness as that of an input signal corresponding with an electron emitting device in the second position.
