1. A data driving apparatus for driving an organic electro luminescence display (OELD) panel, comprising:
- a data driver that outputs data signals formed using a substantially uniform current; and
a data signal controller circuit connected to the data driver for charging a substantially uniform current corresponding to the outputted data signals and for applying the outputted charged current corresponding to the outputted data signals, wherein light is emittable by the OELD panel in the presence of the applied current.

Abstract
A data driving apparatus of an organic electro luminescence display (OELD) panel provides a current to the OELD panel, causing the OELD panel to display pictures. The data driving apparatus may include a data driver for applying data signals using a substantially uniform current; and a data signal controller circuit integrated with the OELD panel for charging and controlling the substantially uniform current in response to the data signals outputted from the data driver so as to apply the data signals to the organic electro luminescence display panel.

16. A method of driving an organic electro luminescence display (OELD) panel having pixel cells arranged at crossings of gate lines and data lines, the method comprising:
-
applying a first data signal from a data driver, wherein the first data signal is formed from a substantially uniform current;
charging a first data signal controller circuit with a second data signal corresponding to the substantially uniform current in response to the outputted first data signal, wherein the first storage means is controllable by a first drive signal during application of a first scan signal;
charging a second data signal controller circuit with a third data signal corresponding to the substantially uniform current in response to the second data signal, wherein the second data signal controller circuit is controllable by a second drive signal between the application of the first scan signal and application of a second scan signal; and
applying the substantially uniform current to the data lines in response to the third data signal during application of the second scan signal. - View Dependent Claims (17, 18, 19, 20)
