  • Publication number: 20150179727
    Abstract: A transparent organic light-emitting display device is described herein. The transparent substrate includes a display area and non-display area adjacent to the display area. An organic light-emitting element is disposed on the display area of the transparent substrate. A first power line is disposed on the display area of the transparent substrate. The first power line supplies power to the organic light-emitting element. A first circuit board comprises a first power supply provided on a first side of the transparent substrate and a second circuit board comprises a second power supply provided on a second side of the transparent substrate. The first power supply is configured to receive power from the second power supply via the first power line. An additional interconnection film to supply power to the first power supply is not required, and thus the width of the bezel can be reduced.

  • Patent number: 8860639
    Abstract: Disclosed are a timing controller and an OLED display device using the same. The timing controller includes a reception unit, an image signal generation unit, and a control signal generation unit. The reception unit receives a plurality of video signals and a timing signal which are transferred from a system. The image signal generation unit realigns the video signals to generate a plurality of image signals. The control signal generation unit analyzes the video signals to determine whether a current input image is a static image or a moving image, and generates a plurality of control signals according to the determined result. When the current input image is determined as the static image, the control signal generation unit generates a plurality of control signals which allow a panel to be driven at a change frame driving frequency lower than a reference frame driving frequency necessary for driving the moving image.
