Abstract
A display device including a liquid crystal display (LCD) panel includes a driving circuit unit to drive the LCD panel, a main controller to generate a data signal that includes predetermined option information, and a timing controller,to detect the option information upon receiving the data signal from the main controller and to adjust an operation state of the LCD panel by transmitting a predetermined operation signal corresponding to the option information to the driving circuit unit. The main controller transmits a color data signal, a V-sync signal, an H-sync signal, a clock signal, and a data enable signal, as the data signal. The option information can be recorded on the data enable signal to change the option information.
