Source sentences:
text: The electron beam must be deflected in order to draw points anywhere on the whole screen surface.
text: Vector and raster scan The electron beam in a CRT may be deflected by drawing the image one line or vector at a time.
text: The deflection system allows the electron beam to be deflected from its straight-line path when it leaves the electron gun.
text: Most smaller CRTs use electrostatic deflection, which occurs when the electron beam is deflected as it passes through charged metal plates; the direction of deflection depends on the amount of charge and polarity of the plates.
text: The electron beam is deflected and modulated in a way which causes it to display an image on the screen.
