Light emitting device and method thereof

A light emitting display comprising:

• a main panel for a frontward display of the light emitting display;
• a sub-panel for a rearward display of the light emitting display;
• a main scan driver for sequentially applying respective selection signals to a plurality of scan lines in the main panel;
• a sub-scan driver for sequentially applying respective selection signals to a plurality of scan lines in the sub-panel;
• a data driver for applying data voltages to selected pixel circuits of the main panel and the sub-panel, the data voltages corresponding to image signals;
• and
• a drive controller for selectively enabling one of the main scan driver and the sub-scan driver while synchronously driving the data driver.

A method for driving a display panel of a light emitting display having a main panel and a sub-panel respectively disposed on front and rear sides of the light emitting display, the method comprising:

• outputting an enable signal for selecting one of a main scan driver for driving the main panel and a sub-scan driver for driving the sub-panel;
• inverting the enable signal;
• sequentially applying selection signals to a plurality of scan lines of the main panel or a plurality of scan lines of the sub-panel in accordance with the enable signal and the inverted enable signal;
• and
• enabling display of a selective one of the main panel and the sub-panel by sequentially applying a plurality of data voltages to pixel circuits selected from the main panel and the sub-panel, the plurality of data voltages corresponding to image signals.
