Color image display device

摘要

A color image display device includes a panel housing a screen on an inner face thereof, an electron gun for emitting electron beams toward the screen, and a cathode ray tube including a shadow mask spaced with a predetermined distance from the screen. A deflection device deflects electron beams from the gun in horizontal and vertical directions to create an image on the screen. The electron gun includes a triode section having a cathode for generating electron beams, a grid electrode aligned to be adjacent to the cathode, and an accelerating electrode aligned to be adjacent to the grid electrode. Video signal voltage is applied to the cathode, and variable voltage is applied to the grid electrode or accelerating electrode.
