31. Example of an electron emitting a ) Thermionic Emitter and an electron accelerating b ) Electron Gun Assembly. 32. The electron gun also needs low-voltage supplies for the correction system, the focusing lens, and the deflection system. 33. 180pxBetween the electron gun and the screen are two opposed pairs of metal plates called the deflection plates. 34. Data was written to the chips using an electron gun , similar to the operation of a television tube. 35. :The electron guns at the back of the TV scan across the screen to draw the new image. 36. Three receivers would be used, each sending its output to a separate electron gun , aimed at its colored phosphor. 37. It used an electron gun arranged at right angles to the display, extending down instead of to the rear. 38. A conventional cathode ray tube ( CRT ) is powered by an electron gun , essentially an open-ended vacuum tube. 39. In the middle one can see the bright spot of the electron gun which generates the primary electron beam. 40. A variant, the Sony Trinitron, used an array of vertical metal strips; the electron guns were side by side.
