Abstract:
The present invention relates to an electroluminescent device, particularly to an organic electroluminescent device reliably receiving driving voltage from a voltage source, and a method of driving the same. A driving circuit of the electroluminescent device includes first to third sub-pixels formed on crossing areas of data lines and scan lines, a pre-charge driving circuit which applies pre-charge current to the data lines of the first to third sub-pixels and a data driving circuit which applies data current to the pre-charged data lines. The pre-charge current is applied to the first to third sub-pixels in different time. The organic electroluminescent device of the present invention and the method of driving the same can reliably receive the driving voltage from the voltage source, and prevent quick flames of the device.
