They have a little sensor and a tiny computer. The sensor puts out an electrical signal voltage that increases with temperature. The computer chip converts that analog voltage signal to a digital number value. It then converts those numbers to light up the correct segments of the characters on the display and make them look like numbers. Anything else it needs to do like timing or alarming are just more jobs for the computer chip.
