A personal computer (PC) includes a main body, a processor received in the main body, and a projecting unit received in the main body and electrically connected to the processor. The PC does not include a built-in display. The processor transmits image signals to the projecting unit, the projecting unit projects images onto a nearby projection surface corresponding to received image signals, so that the nearby projection surface serves as a display of the PC.
