Abstract
An electron source having a cathode and a permanent magnet having perforated channels extending between opposite poles of the magnet. Each channel forms electrons received from the cathode into an electron beam for guidance towards a target. The electron source has applications in a wide range of technologies, including display technology and printer technology.
Claims1
A method for addressing pixels of a display screen having a plurality of pixels, each pixel having successively first, second, and third sub-pixels in line, the method comprising:
- generating a plurality of electron beams, each electron beam corresponding to a different one of the pixels;
- and, deflecting each electron beam to repetitively address the sub-pixels of the corresponding pixel in the sequence second pixel, first pixel, second pixel, third pixel.
