Organic light emitting display

Abstract

An organic light emitting display includes: a first shift register which is electrically coupled with a first clock line, a second inverted clock line, and an initial drive line; a first NAND gate which is electrically coupled with the initial drive line, a first light emitting control line which is an output line of the first shift register, and a third clock line; a second NAND gate which is electrically coupled with the initial drive line, the first light emitting control line, and a fourth clock line; a first pixel part which is electrically coupled with a first scan line which is an output line of the first NAND gate; a second pixel part which is electrically coupled with a second scan line which is an output line of the second NAND gate; a third pixel part which is electrically coupled with the first scan line; and a fourth pixel part which is electrically coupled with the second scan line.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2007-0034285 filed on Apr. 6, 2007, the entire contents of which are hereby incorporated by reference. technical field [0002] The invention relates to an organic light emitting display. Background technique [0003] An organic light emitting display is a display that emits light by electrically exciting fluorescent or phosphorescent compounds and can display images by driving N×M organic light emitting diodes. An OLED consists of an anode (ITO), an organic thin film, and a cathode (metal). The organic thin film is formed of a multilayer structure including an emission layer EML that emits light when electrons and holes recombine, an electron transport layer ETL that transports electrons, and a hole transport layer HTL that transports holes. The organic thin film may also include an electron injection layer EIL that injects electrons and a hole injection layer HIL that injects holes. [0004] As...

Problems solved by technology

However, additional module process operation costs for defective panels required for shorting

When the full inspection is not performed during the module process, since a longitudinal short cannot be detected as a defect during the manufacturing process, the reliability of the product is lowered so that the defect is discovered by the end user of the product
