  • Patent number: 9768275
    Abstract: An array substrate for a liquid crystal display (LCD) device includes a common line and gate lines. The array substrate includes a first, second, and third passivation layer and thin film transistors (TFTs). The second passivation layer includes first and second holes respectively corresponding to a drain electrode and the common line. A common electrode on the second passivation layer includes a first opening corresponding to the TFTs and a second opening in the second hole. A drain contact hole through the third and first passivation layers exposes the drain electrode. A first common contact hole through the third passivation layer exposes the common electrode in the second hole. A second common contact hole through the third and first passivation layers exposes the common line, and a pixel electrode includes a third opening and a connection pattern connecting the common electrode to the common line on the third passivation layer.

  • Patent number: 9311855
    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. The circular arc portion is substantially circular around a center point. A display area is formed in the circular arc portion. The display area has a circular shape centered around the center point. A driving power supply line is formed in the circular arc portion and configured to provide a driving voltage for OLED pixels of the OLED display device. The driving power supply line formed to at least partially surround the display area. A number of power lines electrically connect the driving power supply line to the OLED pixels. A number of bridge lines are formed outside of the display area, where each bridge line connecting one of the power lines with at least one adjacent power line.
