    摘要： A display apparatus includes a plurality of pixels arranged in a matrix. Each pixel includes a light emitting device, a driving transistor for supplying a driving current to the light emitting device, a first switching transistor coupled with the control terminal of the driving transistor to transmit a data voltage, and a second switching transistor coupled with the control terminal of the driving transistor to transmit a reverse voltage. The first and second switching transistors are alternately coupled with scanning lines driven by one of two scanning drivers, and are alternately turned on at different times. The display apparatus periodically applies the reverse voltage to the driving transistors to turn off the diving transistors and to compensate for variation of the threshold voltage of the driving transistors.

    摘要： An OLED includes a display panel, a printed circuit board, a signal transmission member and a voltage transmission member. The display panel has a display region and peripheral regions. The display panel displays an image by an organic light emitting element within the display region. The printed circuit board applies a driving signal and a voltage to the display panel. The signal transmission member electrically connects the printed circuit board to the display panel to transmit the driving signal and the voltage to the display panel. The voltage transmission member transmits the voltage to the display panel. Therefore, an amount of the current applied to the display panel is increased.
