摘要： An organic light emitting display device may include a display panel, a source driving circuit, and a voltage generator. The display panel may include a pixel circuit including a driving transistor to drive an organic light emitting diode. The driving transistor may have four independent terminals including first and second gate electrodes. The source driving circuit may provide a data voltage to the pixel circuit. The voltage generator may apply an independent bias voltage to the second gate electrode of the driving transistor to control a driving voltage range of the driving transistor.

摘要： A display apparatus includes a substrate, a first pixel, a second pixel, a first wire set, and a second wire set. The first pixel and the second pixel overlap the substrate and neighbor each other in a first direction. The first wire set extends in a second direction, includes a first conduction line and a first transmission line, and may transfer a first data signal. The first conduction line is positioned between the substrate and the first transmission line and is connected through the first transmission line to the first pixel. The second wire set extends in the second direction, includes a second conduction line and a second transmission line, and may transfer a second data signal. The second conduction line is positioned between the substrate and the second transmission line and electrically connects the second transmission line to the second pixel.
