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.

Organic light emitting diode display device and fabrication method thereof

An organic electroluminescent display device includes: a first substrate having an active area displaying images and a non-active area surrounding the active area; a switching thin film transistor and a driving thin film transistor connected to the switching thin film transistor in the active area on the first substrate; an organic electroluminescent diode connected to the driving thin film transistor; a dummy metal pattern at a corner portion of the non-active area on the first substrate; a second substrate facing and spaced apart from the first substrate, the second substrate including a groove; and a seal pattern attaching the first and second substrates, wherein the dummy metal pattern overlaps a residue at a corner portion of the groove.

Organic electroluminescent display device having a novel concept for luminous efficiency

The present invention relates to an economically excellent method for manufacturing ultra fine tungsten carbide-cobalt composite powder having tungsten compound and cobalt compound as its raw material. More particularly, the present invention provides a manufacturing method comprising a process for mixing tungsten compounds, cobalt compounds, grain-grown inhibitor compounds and oxide in a mechanical method, a calcination process for removing ammonia and moisture of the mixed powder and forming it into an composite oxide, a reduction process for manufacturing said calcined powder into pure metal powder, a mixing process for adding carbon source to said reduced powder, and a carburization process for manufacturing the mixed powder into a tungsten carbide-cobalt composite powder, which is the final form. Using the manufacturing method of the present invention, ultra-fine tungsten carbide-cobalt composite powder having an ultra-fine particle size of 0.1&#x2dc;0.2 &#x3bc;m, 0.2&#x2dc;0.3 &#x3bc;m,0.3&#x2dc;0.4 &#x3bc;m and high properties such as high hardness, high toughness wherein the binder phase is uniformly mixed can be manufactured. In particular, a tungsten carbide-cobalt composite powder having economic advantages through price competitiveness of the compound using tungsten compounds and cobalt compounds and simplification of process can be manufactured.
