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

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...
