  • Publication number: 20250030893
    Abstract: Provided is an apparatus and method for encoding/decoding a moving picture based on adaptive scanning.

  • Patent number: 9318054
    Abstract: An organic light emitting diode (OLED) display device and a method of driving the same are provided. A time point at which each of transistors is turned on is controlled without using an additional transistor so that a node connected to a source electrode of a driver transistor can be floated, and a node connected to a gate electrode of the driver transistor can be initialized to an initialization voltage level. Thus, initialization characteristics can be improved to enhance degradation of response characteristics and luminance, and a threshold voltage of the driver transistor and occurrence of a ripple at a high-potential voltage terminal can be compensated.

  • Patent number: 9035854
    Abstract: An organic light emitting diode (OLED) display device and a fabrication method thereof are provided. In the OLED display device, when an existing power wiring using a metal used for a data wiring is divided based on a common electrode marginal region as a boundary so as to be used as a wiring as well as as the power wiring, the reduced width of the wiring is compensated for by increasing the thickness of the wiring by using a metal for an anode or a cathode, thus reducing the left and right bezel widths.
