  • Organic light emitting display device
    Publication number: 20060017665
    Abstract: 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.
