摘要： A wire shaped electron source includes a heating core wire (10, 20a and 20b), an insulator (11, 22a, and 22b) partially provided on the heating core wire (10, 20a, and 20b), and an electron emission material provided on the heating core (10, 20a, and 20b) between the insulators (10, 20a, and 20b). The thickness of the electron emission material is less than the height of the insulators (10, 20a, and 20b).

摘要： A method of driving an image display device is disclosed in which electron beams from line cathodes (1) are impinged upon a display screen (9) through beam modulating and deflecting electrodes (6, 7, 7′, 8, 8′) to display an image. Each beam roughly lands onto a predetermined position on the screen by a stepped deflection voltage waveform to form a spot on the screen while the beam is deflected around the predetermined position by an unstepped deflection voltage waveform. The timing of application or the pulse width of a driving pulse signal for the beam modulating electrode is controlled in a form temporally related to the driving of the beam deflecting electrode to control the landing position or diameter of the spot on the screen. In the case where the driving pulse signal is a signal the pulse width of which is modulated by a video signal, the pulse width is changed in accordance with the level of the video signal and equally in positive and negative directions around the instant of time when a signal pulse having the minimum width necessary for representation as an image is to be generated.
摘要翻译：公开了一种驱动图像显示装置的方法，其中来自线阴极（1）的电子束通过光束调制和偏转电极（6,7,7分钟，8,8分钟）撞击在显示屏（9）上以显示一个图像。每个光束通过阶梯偏转电压波形大致落在屏幕上的预定位置，以在光束通过非偏移偏转电压波形在预定位置偏转时在屏幕上形成点。用于光束调制电极的驱动脉冲信号的施加时间或脉冲宽度以与光束偏转电极的驱动相关的形式被控制，以控制屏幕上的光斑的着落位置或直径。在驱动脉冲信号是脉冲宽度由视频信号调制的信号的情况下，脉冲宽度根据视频信号的电平而变化，并且在时间周期的同时以正负方向改变将产生具有作为图像表示所需的最小宽度的信号脉冲。
