Abstract:
An organic light-emitting diode (OLED) display having thin film transistors (TFTs) is disclosed. In one aspect, TFTs of the OLED display include a substrate and a first semiconductor layer formed over the substrate and including first channel, source, and drain regions and a lightly doped region between the first channel region and the first source and drain regions. The OLED display also includes a second semiconductor layer formed over the substrate and including second channel, source, and drain regions. The OLED display further includes first and second gate electrodes formed over the first semiconductor layer and a third gate electrode formed over the second semiconductor layer. The width of the second gate electrode is less than that of the first gate electrode and the lightly doped region overlaps a portion of the first gate electrode and does not overlap the second gate electrode.
