Abstract

An organic light emitting diode display is disclosed. The display includes scan lines formed over a substrate and configured to transmit scan signals. The first data line and the second data line are adjacent to each other and cross the scan line. The first data line and the second data line are configured to carry a data voltage. A driving voltage line crossing the scan line is configured to transmit a driving voltage, and the switching transistor is electrically connected to the scanning line and the data line, and includes a switching drain electrode configured to output a data voltage. The drive transistor includes a drive gate electrode and a drive source electrode electrically connected to the switch drain electrode. The OLED is electrically connected to the driving drain electrode of the driving transistor, and the connector is connected to the driving gate electrode of the driving transistor and interposed between the first data line and the second data line.

Description

[0001] related application [0002] This application claims priority and benefit from Korean Patent Application 10-2015-0022527 filed in the Korean Intellectual Property Office on February 13, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The described technology generally relates to organic light emitting diode displays. Background technique [0004] An organic light emitting diode (OLED) includes two electrodes and an organic emission layer therebetween. Electrons injected from one electrode and holes injected from the other electrode combine with each other in the organic emission layer to generate excitons, and the excitons emit energy in the form of light. An OLED display comprises a matrix of pixels, each pixel comprising i) an OLED which is a self-emitting device, ii) a plurality of thin film transistors (TFTs) for driving the OLED, and iii) a storage capacitor. These transistors and storage capacitors are connecte...
