摘要： Disclosed is a method for fabricating a thin film transistor. Specifically, the method uses local oxidation wherein a portion of a transparent metal oxide layer is locally oxidized to be converted into a semiconductor layer so that the oxidized portion of the transparent metal oxide layer can be used as a channel region and the unoxidized portions of the transparent metal oxide layer can be used as source and drain electrodes.The method comprises the steps of forming a gate electrode on a substrate and forming a gate insulating layer thereon, forming a transparent metal oxide layer on the gate insulating layer, forming an oxidation barrier layer on the transparent metal oxide layer in such a manner that a portion of the transparent metal oxide layer positioned over the gate electrode is exposed, and locally oxidizing only the exposed portion of the transparent metal oxide layer to convert the exposed portion into a semiconductor layer.

摘要： Disclosed are an Organic Light Emitting Diode (OLED) display device having a pixel circuit which use a thin film transistor (TFT) as an active device and a driving method thereof. The OLED display device can constantly obtain luminance of the light emitting elements by elapsed time, because the brightness of the pixel for the signal voltage is not varied by a characteristic variance of the transistor (e.g., a driving element) and the OLED. Accordingly, the OLED display device according to the present invention can minimizes the variance of the pixel brightness due to deterioration of the transistor and the OLED caused by usage for a long time and increase life span of the display device. Further, the OLED display device can display high quality of the image even in case of the high precision display, because it is controlled to flow the current to OLED included in each pixel.
