A system for displaying images is provided. The system comprises a reference voltage source, a digital-to-analog converter, a multiplier and a buffer. The reference voltage source outputs a voltage signal, wherein the magnitude of the voltage signal is 1/N of a driving voltage. The digital-to-analog converter converts the voltage signal to a first voltage. The multiplier receives and multiplies the first voltage by N to output the driving voltage. The buffer receives the driving voltage to drive a data line.

The present invention relates to a tandem organic light emitting device, which reduces the driving voltage by using a non-doping material having both the electron transporting and hole transporting abilities to act, respectively, as an electron transporting layer and a hole transporting layer that are in contact with the connecting layer. The tandem organic light emitting device does not have to double its driving voltage as a result of the increasing of the number of the emitting element contained therein. However, the brightness and the current efficiency of the device of the present invention will be higher than the theoretical fold value calculated in accordance with the number of emitting element contained in the device.
