ABSTRACT:
An apparatus for generating a planar light source and method for driving the same is provided. The apparatus for generating a planar light source comprises an emitting layer disposed not only on a cathode electrode, but also on a gate electrode as well. Accordingly, by applying an AC voltage to the apparatus, a duty cycle of the AC voltage can reach 100% so as to enhance the brightness to the extent that the apparatus is applied a DC voltage.
