Abstract

Official abstract text for this publication.

The present disclosure discloses a backplane for an organic light emitting display device, a method for fabricating the same, and an organic light emitting display apparatus. The backplane includes a substrate on which a wiring structure and a thin film transistor are provided, wherein the wiring structure includes an initializing voltage input line which is provided in the same layer and made of the same material as electrodes of the thin film transistor.

First claim

Opening claim text (preview).

What is claimed is: 1. A backplane for an organic light emitting display device, comprising: a substrate, an initializing voltage input, a reference voltage input line, a thin film transistor, and an organic light emitting diode, disposed on the substrate, wherein the thin film transistor comprises a first electrode connected to a first electrode line, a second electrode connected to a second electrode line, and a control electrode connected to a control electrode line, wherein the initializing voltage input line is provided in the same layer and is made of the same material as one of the first electrode, the second electrode and the control electrode of the thin film transistor and one of the first electrode line, the second electrode line and the control electrode line to which the one of the first electrode, the second electrode and the control electrode is connected, wherein the reference voltage input line is provided in the same layer and is made of the same material as an anode of the organic light emitting diode, and wherein the initializing voltage input line and the reference voltage input line are provided in different layers. 2. The backplane according to claim 1 , wherein the first electrode is formed of at least one of titanium, chromium, molybdenum, tantalum, and aluminum, the second electrode is formed of at least one of titanium, chromium, molybdenum, tantalum, and aluminum. 3. The backplane according to claim 1 , wherein the control electrode is formed of at least one of titanium, chromium, molybdenum, and tantalum. 4. An organic light emitting display apparatus, comprising a backplane according to claim 1 . 5. The backplane according to claim 1 , wherein the first electrode is a source, the second electrode is a drain, and the control electrode is a gate. 6. The backplane according to claim 1 , wherein the initializing voltage input line is provided in the same layer and is made of the same material as the first electrode and the second electrode. 7. The backplane according to claim 1 , wherein the initializing voltage input line is provided in the same layer and is made of the same material as the control electrode.
