Not all... Older ones worked on a 'grid' system. There were sensors built into the edge oif the monitor - which detected where you were touching the screen.
Modern screens use TFT (Thin Film Transistor) technology... The screen is made up of two thin layers of conductive material and normally, no current flows between the two layers. When you touch the screen, you force the two layers closer together (temporarily). This changes the resistance between the layers, and the computer converts the change to commands.
