摘要： An electron emitting apparatus includes a lower electrode, an emitter section made of a dielectric material, a plurality of upper electrodes having micro through holes, and a collector electrode opposing the upper electrodes. In this electron-emitting apparatus, electrons are accumulated in the emitter section by controlling the potential difference (drive voltage) between the lower and upper electrodes with respect to the potential of the lower electrode to a negative predetermined voltage. At this time, the collector electrode of the electron-emitting apparatus is grounded. Thus, unnecessary electron-emitting is suppressed. Subsequently, the drive voltage is changed to a positive predetermined voltage. As a result, polarization reversal occurs in the emitter section, and accumulated electros are emitted through the micro through holes in the upper electrodes by Coulomb repulsion. At this time, a positive voltage Vc is applied to the collector electrode to give large energy to accelerate the electrons.

摘要： An electron-emitting element has an electron emission unit including a lower electrode, an emitter section composed of a dielectric material, and an upper electrode having a plurality of micro through holes; and a power supply for applying a power supply voltage to the electron emission unit. During the period between the point at which emission of electrons accumulated in the emitter section is started and the point at which the electron emission is completed, the power supply generates a first power supply voltage, whose absolute value changes with forming a sinusoidal wave so that the potential of the upper electrode is higher than the potential of the lower electrode. During the period between the point at which the electron accumulation in the emitter section is started and the point at which the electron accumulation is completed, the power supply generates a second power supply voltage whose absolute value increases with forming a sinusoidal wave so that the potential of the lower electrode is higher than the potential of the upper electrode.

摘要： A light-emitting device includes electron emitters for planarly emitting electrons, collector electrodes disposed to face corresponding one electron emitter, and a phosphor formed near the collector electrodes. During a period when electrons are emitted from the electron emitter, a collector voltage is applied to each of the collector electrodes in the sequence. Electrons are attracted toward a region of the phosphor in the vicinity of the collector electrode to which the collector voltage is applied, and impinge on the region of the phosphor, whereby light is emitted therefrom. The remaining region of the phosphor emit afterglow.

摘要： A light source has a transparent substrate, a fixed substrate disposed in facing relation to the transparent substrate, at least one electron emitter disposed on the fixed substrate, a phosphor layer disposed on a surface of the transparent substrate which confronts the fixed substrate, and a trajectory deflector for deflecting the trajectory of a pulsed electron flow intermittently emitted from the electron emitter. The pulsed electron flow is deflected by the trajectory deflector to two-dimensionally scan a position of the phosphor layer which is irradiated with the pulsed electron flow for thereby spreading the pulsed electron flow.
