Abstract:
1. An image display apparatus comprising: a plurality of electron emitting devices; a plurality of light emitting regions arranged to be distanced from the electron emitting devices, and emitting lights by being irradiated with electrons emitted from the electron emitting devices, the plurality of light emitting regions corresponding to the plurality of electron emitting devices respectively, the plurality of electron emitting devices including at least one first electron emitting device and at least one second electron emitting device; an electron shield member which suppresses irradiation of electrons, resulting from electron-emission from the first electron emitting device, to a light emitting region corresponding to the second electron emitting device, wherein there is an increase in a quantity of emitted light of the light emitting region corresponding to the second electron emitting device, the increase resulting from electron-emission from electron emitting devices proximate to the second electron emitting device, changes according to a quantity of electrons, resulting from electron-emission from the proximate electron emitting devices, shielded by the electron shield member; and a driving circuit which outputs a driving signal for driving the electron emitting devices, wherein the driving circuit includes a correction circuit for correcting a signal, the correction circuit being a circuit which outputs a corrected signal for the second electron emitting device corresponding to the light emitting region having a first increase in a quantity of emitted light, the first increase resulting from the electrons emitted from electron emitting devices proximate to the second electron emitting device, wherein the first increase is smaller than an increase resulting from electron-emission from said proximate electron emitting devices not being suppressed by said electron shield member, so as to increase the quantity of the light of the light emitting region corresponding to the second electron emitting device, and the driving signal is generated based on the corrected signal.
