CRTs have a distinctive funnel shape. At the very back of a monitor is an electron gun. The electron gun fires electrons towards the front through a vacuum which exists in the tube of the monitor. Electrons that pass through the mesh then hit the phosphor coating which is on the inside of the glass screen.
A CRT monitor contains millions of tiny red, green, and blue phosphor dots that glow when struck by an electron beam that travels across the screen to create a visible image. The anode is positive, so it attracts the electrons pouring off the cathode. …
Moreover, Are CRT monitors worth anything?
CRT tubes have a fair amount of glass but it’s hard to recycle because of the phosphors. There are trace amounts of rare metals in the circuitry but also somewhat difficult to recycle. Bottom line is that there is little value in CRT monitors.

How do LCD monitors work?
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome.
