Abstract:
1. A dual display device, comprising: 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, wherein the first receiver comprises a first memory unit which stores the image signals, wherein the signal controller further comprises a signal arrangement unit generating the first output image signal and the second output image signal based on the input image signals received from at least one of the first and second receivers, and outputting the first output image signal and the second output image signal to the data driver in an alternating fashion, and wherein the input image signals comprises a first input image signal to be displayed on the first surface and a second input image signal to be displayed on the second surface, the first receiver receives the first input image signal to store the same in the first memory unit, the second receiver receives the second input image signal to output the same, and the signal arrangement unit generates the first output image signal from the first input image signal and the second output image signal from the second input image signal.
