    摘要: In manufacturing or adjusting an electron-emitting device which has at least two electrodes and emits electrons by applying a voltage between the two electrodes, or before performing normal driving, a voltage V1 is applied which has the following relationship with a maximum voltage value V2 applied as a normal driving voltage to the electron-emitting device between the two electrodes. Giving a current I flowing upon application of a voltage V when the voltage V falling within a voltage range causing electron emission upon application of the voltage between the two electrodes is applied between the two electrodes: I=f(V) and letting f′(V) be the differential coefficient of f(V) at the voltage V, the voltage V1 has a relationship with the voltage V2 that satisfies, upon application of the voltage, the first condition: f(V1)/{V1·f′(V1)−2f(V1)}>f(V2)/{V2·f′(V2)−2f(V2)} Further, letting Xn-1 be the value of the right side of inequality (2) upon a first application of the pulse-like voltage V2 when the voltage V2 is applied as pulses successively twice between the two electrodes after application of the voltage V1, and Xn be the value of the right side of inequality (2) upon a second application of the pulse-like voltage V2, the relationship with the voltage V2 satisfies the second condition that Xn−1 and Xn satisfy: (Xn-1−Xn)/Xn-1≦0.02

    摘要: Provided is an image display apparatus capable of displaying a preferable image whose dark place contrast has a large value and whose color-reproducibility and gray-level reproducibility are excellent. A voltage level of a scanning selective signal is changed in response to a request from an outside or the like, so that a black level luminance is reduced to improve dark place contrast. In addition, when the voltage level of the scanning selective signal is changed, a conversion table for converting an input luminance into a modulation signal is changed to another conversion table. Therefore, for example, it is possible to maintain a display gray-level characteristic before and after the voltage level of the scanning selective signal is changed.

    摘要: An electron source comprises a plurality of electron-emitting devices and a drive means for driving the devices. The drive means applies a voltage above a threshold level to selected ones of the plurality of electron-emitting devices according to an image signal to cause the selected devices to emit electrons. The drive means also applies a voltage pulse for bringing the plurality of electron-emitting devices into a high resistance state. The voltage pulse for bringing into a high resistance state has a polarity reverse to that of the voltage for causing electron emission and has a voltage rising rate of greater than 10V/sec.
