Claim:
1. A dual display comprising: a first display panel including a plurality of first pixels and a first emission driving circuit configured to transmit a plurality of first emission control signals to the first pixels; a second display panel including a plurality of second pixels and a second emission driving circuit configured to transmit a plurality of second emission control signals to the second pixels, wherein the second display panel is adjacent to the first display panel; a first data driver configured to i) transmit a first data signal to the first display panel, ii) transmit a first emission driving circuit control signal to the first emission driving circuit to control the first emission driving circuit, and iii) transmit a first emission driving circuit disable control signal to the second emission driving circuit to control the second pixels to not emit light; a second data driver configured to i) transmit a second data signal to the second display panel, ii) transmit a second emission driving circuit control signal to the second emission driving circuit for controlling the second emission driver, and iii) transmit a second emission driving circuit disable control signal to the first emission driving circuit to control the first pixels to not emit light; a first switch directly connected to the first emission driving circuit and configured to electrically connect the first emission driving circuit to the second data driver; a second switch directly connected to the second emission driving circuit and configured to electrically connect the second emission driving circuit to the first data driver; and a power supply configured to provide first and second power voltages different from each other to both of the first and second display panels, wherein the second data driver is further configured to not operate when the first emission driving circuit disable control signal is transmitted to the second emission driving circuit, and wherein the first data driver is further configured to not operate when the second emission driving circuit disable control signal is transmitted to the first emission driving circuit.
