Abstract
A dual display device includes a display panel having a first surface and an opposing second surface, and including a plurality of first pixels displaying an image on the first surface and a plurality of second pixels displaying an image on the second surface, a gate driver supplying gate signals to the first and second pixels, a signal controller including first and second receivers receiving input image signals and generating first and second output image signals based on the input image signals, and a data driver analog-converting the first and second output image signals to generate first and second data voltages, respectively, and supplying the first and second data voltages to the first and second pixels, respectively. By using two different interfaces, memories can be reduced by driving transmissive pixels and reflective pixels independently, and different normal images can be displayed on both surfaces of the display panel. When the same image is displayed on both surfaces, only one interface is selectively driven to thereby reduce power consumption.
