Abstract
Official abstract text for this publication.
A pixel and an organic light emitting display device using the same are provided. The pixel includes an organic light emitting diode. A first transistor has a second electrode coupled to the organic light emitting diode, and controls the amount of current supplied to the organic light emitting diode. A third transistor is coupled between a reference power source and a first node, and is turned on when a scan signal is supplied to a scan line. A second transistor is turned on when the scan signal is supplied to the scan line, and electrically couples a data line to a second node. A fourth transistor is coupled between the first and second nodes, and is turned off when an emission control signal is supplied to an emission control line. A storage capacitor is coupled between the second node and a first electrode of the first transistor.
First claim
Opening claim text (preview).
What is claimed is: 1. A pixel circuit comprising: an organic light emitting diode; a first transistor having a second electrode coupled to the organic light emitting diode, the first transistor being configured to control an amount of current supplied to the organic light emitting diode; a third transistor coupled between a reference power source and a first node, the first node being directly coupled to a gate electrode of the first transistor and also being directly coupled…
