How does CRT create the image?
Consists of a cathode and anode within a vacuum tube. Cathode boils off a cloud of electrons, and then a potential difference is placed on the tube. A stream of electrons is sent across to the anode, which is the case of the monitor is a sheet of glass coated with a phosphor layer. Electrons then strike the phosphor on the glass, causing glass to emit a color based intensity where most electrons strike. .. does this all in a raster scan pattern
