  • Publication number: 20130208015
    Abstract: An organic light emitting diode (OLED) display is disclosed. In one embodiment, the OLED display includes a panel including pixels which are configured to control an amount of current that flows from a first power source to a second power source to generate an image of predetermined brightness. The display may also include at least one first power source line formed on a top of the panel and at least one second power source line positioned on a bottom of the panel to face the first power source line. The display may further include a first switch configured to alternately supply the first power source to the first power source line and the second power source line.
