Abstract: A display device includes: a timing controller which receives a data control signal from, or outputs the data control signal to, an external device through a wiring, and selectively outputs a power control signal, a display device data signal and a common voltage control signal to a first or second serial communication wiring based on a driving mode determined based on the data control signal; a memory unit which stores the display device data signal, receives the display device data signal from, or outputs the display device data signal to, the timing controller through the first serial communication wiring; and a power generator which receives or outputs the power control signal or the common voltage signal from or to the timing controller through the second serial communication wiring, and generates a voltage adjusted by the power control signal and a common voltage adjusted by the common voltage control signal.
