Abstract
A display device includes a display panel, a gate driver, a data driver, and a signal controller that receives digital input signals including an input control signal and an input image signal in series through two or less input terminals, and processes the input image signal and applies the processed input image signal to the data driver, wherein the signal controller includes a receiver receiving the input signals and a clock generator generating a clock signal based on the input control signal, the signal controller processing the input image signal in synchronization with the clock signal. Thus, the structure of the display device can be simplified while signal loss and noises can be reduced.
