Whole functioning of cathode ray tube electronic projectors is like CRT tv established. These projectors may possibly be configured with 1 RGB coloration tube that has a few hues red, green and blue with a solitary lens, one particular black & white tube with a rotating color wheel or three RGB color tubes with 3 lenses.
