Embodiment Construction

[0019] Hereinafter, specific exemplary embodiments will be described with reference to the accompanying drawings. Here, when a first element is described as being coupled to a second element, the first element may be not only directly coupled to the second element but also indirectly coupled to the second element via a third element. Furthermore, some elements not necessary for a complete understanding of the invention have been omitted for the sake of clarity. Furthermore, the same reference numerals denote the same elements throughout.

[0020] In the following, reference will be made to Figure 1 to Figure 7 Embodiments that can be carried out by those skilled in the art are described.

[0021] figure 1 An organic light emitting display according to one embodiment is shown. exist figure 1 In this example, although the scan driver 10 and the emission driver 30 are shown as being separated from each other, the emission driver 30 may be included in the scan driver 10 .

Abstract

The method provides an emission driver and organic light emitting display using the same. An organic light emitting display which prevents unnecessary illumination of the organic light emitting diodes is disclosed. The display has an emission driver which globally turns off all of the pixels during an initialization period, and allows normal operation during other times.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2008-0020021 filed with the Korean Intellectual Property Office on Mar. 4, 2008, the entire contents of which are hereby incorporated by reference. technical field [0002] The field relates to an emission driver and an organic light emitting display using the emission driver, and more particularly, to an emission driver and an organic light emitting display using the emission driver to provide an emission control signal to an emission control line monitor. Background technique [0003] Recently, various flat panel displays having reduced weight and volume (which are not advantageous for cathode ray tubes) have been developed. The flat panel display may take the form of, for example, a liquid crystal display, a field emission display, a plasma display panel, and an organic light emitting display, among others. [0004] Organic light emitting displays display images using organic light emitting di...
