  • Power sharing lines for powering a small form factor OLED display device
    Patent number: 9349322
    Abstract: An organic light emitting diode (OLED) display device includes a substrate including a circular arc portion and a driving circuit connecting portion connected to the top of the circular arc portion. A circular display area is formed in the circular arc portion. The display area includes a number of OLED pixels, where each OLED pixel connected to one of a number of power lines. A driving power supply line provides a driving voltage for the OLED pixels. The driving power supply line includes a circular shape and is formed around the display area. A number of power sharing lines extend from a lower area of the driving power supply line, where each of the power sharing lines is connected to a different subset of the power lines.
