摘要： It is an object of this invention to provide an electron generating apparatus which eliminates, with a simple process, variations in electron-emitting characteristics of electron sources caused by various factors, a method of adjusting the characteristics of the electron generating apparatus, a method of manufacturing the electron generating apparatus, and an image forming apparatus using the electron generating apparatus. Characteristic measuring voltages are applied from pulse generators (6, 7) to each surface-conduction emission device of a display panel (1), so that the electron-emitting characteristics are measured by a current detector (12). A pulse peak value setting circuit (8) is controlled to output a voltage signal having a peak value determined in the above manner, and characteristic shift voltages are applied from the pulse generators (6, 7) to the surface-conduction emission device. With this process, the electron-emitting characteristics of the surface-conduction emission devices are equalized. The characteristic shift voltage is higher than the characteristic measuring voltage, and the characteristic measuring voltage is higher than a driving voltage.

摘要： In order to prevent voltage drops across the wiring resistances in a multi-electron source having a plurality of electron emitters wired in the form of a matrix of a plurality of data wiring layer electrodes and a plurality of scanning wiring layer electrodes, a constant current signal is output to each data wiring layer electrode. At this time, each non-selected data wiring layer electrode tends to be set at a high impedance and vary in potential, resulting in an abnormal turn-on operation or an electron orbit shift. A driving circuit for solving this problem is provided. A switch for switching a constant current output unit for outputting a constant current regardless of the impedance of a signal output destination, and a constant voltage output unit for outputting a constant voltage regardless of the impedance of a signal output destination is connected to each data wiring layer electrode. For example, a constant-current circuit (17) as a current output unit always outputs the same current (I1 to In) to a switch (30). A pulse width signal (PW1 to PWn) from a pulse-width modulation circuit (7) serves to switch the mode of outputting a current (I1 to In) to a data wiring layer electrode (D y1 to D yn, ) and the mode of fixing a data wiring layer electrode to voltage GND.

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.
