Abstract
Official abstract text for this publication.
An organic light emitting display includes a display unit that includes pixels coupled to scan lines, control lines, and data lines; a control line driver for providing control signals to the respective pixels through the control lines; a first power driver for applying a first power to the pixels of the display unit; and a second power driver for applying a second power to the pixels of the display unit, wherein the first power and/or the second power is applied to the pixels of the display unit, having voltage values at different levels, during periods of one frame, and the control signals and the first and second powers are concurrently provided to all of the pixels.
First claim
Opening claim text (preview).
What is claimed is: 1. A driving method of an organic light emitting display, the method comprising: (a) initializing voltages of respective nodes of a plurality of pixel circuits included in respective pixels by concurrently applying a first power, a second power, scan signals, control signals, and data signals, all having voltage values at respective levels, to all of the pixels in a display unit; (b) decreasing a voltage of an anode electrode of an organic light emitting diod…
