Active matrix organic light emitting device having series thin film transistor, and fabrication method therefor

摘要

The series TFT comprises a semiconductor layer including a first body, a second body and a connecting portion serially connecting the first body to the second body. The first body has a first channel region and first source/drain regions positioned at both sides of the first channel region. The second body has a second channel region and second source/drain regions positioned at both sides of the second channel region. And the connecting portion is interposed between the first source/drain region and the second source/drain region to serially connect the first body to the second body and having a conductive type different from that of at least one of the first source/drain region and the second source/drain region. A first gate is positioned to correspond to the first channel region, and a second gate is positioned to correspond to the second channel region. An active matrix OLED can be manufactured using such series TFTs.
