Abstract: Disclosed herein are a light-emitting diode (LED) device, and an ink composition including the same, which can reduce an exposed area of a photoactive layer exposed at a surface to prevent a decrease in efficiency due to a surface defect, and repair the surface defect and minimize degradation in light emission efficiency due to the surface defect even when the surface defect occurs to maintain high efficiency in light extraction efficiency and, simultaneously, minimize a side surface contact through a mounting method using dielectrophoresis when LED devices are self-aligned on a mounting electrode to improve a drivable (or light emittable) mounting efficiency.

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: The present invention relates to a light emitting diode (LED) electrode assembly, and more particularly, to an ultra-thin fine LED electrode assembly, a method of manufacturing the same, and a light source including the same. Accordingly, as a surface of the ultra-thin fin LED element, which is in contact with an electrode, is a surface rather than a side surface through dielectrophoresis, drivable mounting efficiency increases, and at the same time, one specific surface is in selective contact with a mounting electrode, and thus a range of selection for driving power may be expanded to include a direct current (DC) power. Therefore, an LED electrode assembly having higher brightness is achieved advantageously.
