How Are Televisions Made?

The human brain is an amazing thing. Television screens and technology capitalize on two facets of the human brain when concerned with vision. One is the ability of the human brain to focus or visualize a comprehensive image made up of dots. Individual dots for instance when placed near each other in large numbers can be interpreted by the brain to resemble a face or an image.

Secondly when individual frames or images are flashed at high speed in front of the brain they appear to be one seamless occurrence of events. The same thing was used in animation cartoons of old. Now the television does just these two things. It creates images by targeting electrons on to phosphors coated on the TV screen creating images and does this at such high speed that it appears as a seamless film. To do this the television screen uses a cathode ray tube composed of a cathode, anode, conductive coating, a vacuum, a phosphor coated screen and electron beams.
