The principle of color image reproduction by color picture tube The principle of reproducing color images by color picture tube 1: The three electron guns arranged in character are excited by the three primary color signals of red, green and blue respectively, and the three emitted electron beams converge in the small hole of the shadow mask plate They bombarded the corresponding red, green, and blue fluorescent dots to make them glow. Because the three points are close to each other, the colored light emitted by each group gives the impression of mixing the three points.

The principle of the color picture tube reproducing the color image 2: The hue and saturation of the mixed color depend on the size of the energy carried by the three electron beams, that is, the size of the three signal voltages ER, EG, and EB sent from the sending end. If the brightness of the three-color fluorescent dots is proportional to the brightness of the corresponding pixels of the three primary color light images of the captured image, the starting-end color image can be reproduced on the fluorescent screen.
