ABSTRACT:
An organic electroluminescent (EL) display panel which includes a pixel circuit is provided. The pixel circuit includes a first transistor, a second transistor, and a display element. The first transistor has control and main electrodes and outputs a current which corresponds to a voltage charged in at least one capacitor being provided between the control and main electrodes. The second transistor has a second control electrode coupled to the control electrode of the first transistor. The second electrode is diode-connected. The display element displays image data corresponding to an amount of the current output by the first transistor. The first transistor and the display element are electrically decoupled during the first period for applying a pre-charge voltage to the control electrode of the first transistor and the second period for applying the data voltage to the control electrode of the first transistor.
