Abstract: The present invention relates to an LED electrode assembly, and more particularly, to an ultra-thin pin LED electrode assembly, a manufacturing method thereof, and a light source including the same. According to the present invention, the surface of the ultra-thin pin LED device in contact with the electrode through dielectrophoresis becomes a surface rather than a side surface, thereby increasing the drivable mounting efficiency. Further, by allowing a specific surface to selectively contact the mounting electrode, the range of driving power selection can be extended to DC power. Accordingly, it is advantageous to achieve a higher luminance LED electrode assembly.

Abstract: The present invention relates to an LED device, and more particularly, to an ultra-thin pin LED device and an ink composition including the same. According to the present invention, it is advantageous to achieve higher luminance and light efficiency by increasing the emission area and preventing or minimizing the reduction in efficiency due to surface defects. In addition, it is very suitable for a dielectrophoretic method of self-aligning the devices on electrodes by electric field, and the drivable mounting efficiency can be increased by ensuring that the surface in contact with the electrodes is a surface other than the side surfaces.

Abstract: A transition metal-based heterogeneous carbonylation reaction catalyst has an excellent catalytic activity and selectivity in the carbonylation reaction and is easily separated from a product, by crosslinking polymerizing a transition metal-based homogeneous catalyst unit through a Friedel-Craft reaction. The catalyst may be used in a method for preparing lactone. The transition metal-based heterogeneous carbonylation reaction catalyst allows to produce lactone or succinic anhydride with an epoxide compound while showing a high selectivity, and can be applied in industrial very usefully due to easy separation from the product and thus reusing thereof.
