Abstract: An organic light emitting device enables improvement on the loss of optical extraction efficiency due to total reflection and optical waveguide effects. The organic light emitting device has a structure wherein a first electrode, an organic substance layer, and a second electrode are sequentially laminated on a substrate, a random nano structure having a fine pattern of a peaks-and-valleys shape is formed between a substrate and a first electrode to extract any light that is wasted due to total reflection and an optical waveguide mode to the outside of the substrate so that an organic light emitting device with improved external quantum efficiency can be realized, and optical extraction patterns and color changes due to visual field angles can also be improved.

Abstract: The present invention relates to a powerless automatic tee up machine, which repeats the transporting of the golf balls onto a golf tee through potential energy, a cam curve, a principle of balancer and a link system without using power, and which has a maximally simplified structure to significantly reduce manufacturing costs as compared to conventional machines.
