20130071278 | SCROLL COMPRESSOR - The present disclosure relates to a scroll compressor. According to the present disclosure, in a shaft penetration scroll compressor in which an eccentric portion of the rotation shaft is overlapped with a orbiting wrap of the orbiting scroll in a radial direction, an oil hole for supplying oil inhaled through the oil passage of the rotation shaft to a thrust bearing surface between the scroll compressor and orbiting scroll may be formed at the fixed scroll, and thus the orbiting scroll may be supported with the pressure of oil supplied to the thrust bearing surface through the oil hole to prevent tilting of the orbiting scroll due to the eccentricity of a gas force in advance, thereby enhancing the reliability and performance of the compressor. | 03-21-2013 |
20130078129 | SCROLL COMPRESSOR - The present disclosure relates to a scroll compressor. According to the present disclosure, in a shaft penetration scroll compressor in which an eccentric portion of the rotation shaft is overlapped with a orbiting wrap of the orbiting scroll in a radial direction, a back pressure chamber formed at a rear surface of the orbiting scroll may be eccentrically formed from the circular center around a discharge port to correspond to the eccentric discharge port, thereby effectively preventing tilting of the orbiting scroll due to the eccentricity of a gas force generated while the discharge port is eccentrically formed. | 03-28-2013 |
20140348680 | SCROLL COMPRESSOR - A scroll compressor is provided, in which a fixed side discharge opening is formed eccentric from a geometrical center of an orbiting scroll toward an orbiting side discharge opening, so as to overlap the orbiting side discharge opening across a relatively wide area. This may reduce flow resistance between the orbiting side discharge opening and the fixed side discharge opening. Accordingly, a refrigerant compressed in a final compression chamber may be rapidly discharged without being blocked by an upper frame, while maintaining a proper discharge pressure. Since uniform pressure may be maintained in compression chambers positioned at both sides of the scroll compressor, input losses due to over-compression may be reduced. | 11-27-2014 |
20150192121 | SCROLL COMPRESSOR - A scroll compressor is provided that may include a casing; a discharge cover fixed to an inner space of the casing, that divides the inner space of the case into a suction space and a discharge space; a main frame in the casing, and spaced from the discharge cover; an orbital scroll that performs an orbital motion on the main frame; a non-orbital scroll coupled to the main frame so as to be movable up and down with respect to the orbital scroll, that forms a suction chamber, an intermediate pressure chamber, and a discharge chamber together with the orbital scroll; and a back pressure plate provided between the discharge cover and the non-orbital scroll, that forms a back pressure chamber that communicates with the intermediate pressure chamber. With such a configuration, a bypass valve may be easily installed, and application of an overload minimized. | 07-09-2015 |

20150253623 | BACKLIGHT UNIT AND DISPLAY DEVICE HAVING THE SAME - A display device includes a display panel and a backlight unit. The display panel is curved along a first direction. The backlight unit includes an upper surface, and a lower surface having a curvature different from a curvature of the upper surface. The backlight unit includes a bottom cover that includes a bottom portion, and a sidewall extending from the bottom portion, a plurality of light emitting diodes on the bottom portion and generating light, and a diffusion plate on the light emitting diodes. In the first direction from a center portion of the bottom portion to an outer portion of the bottom portion, pitches between the light emitting diodes along a surface of the bottom portion, are proportional to distances between the light emitting diodes and the diffusion plate in a direction substantially normal to positions of the bottom portion at which the light emitting diodes are disposed. | 09-10-2015 |

20120075552 | BACKLIGHT ASSEMBLY AND DISPLAY APPARATUS HAVING THE SAME - A backlight assembly includes a light source part, a light guide plate, a container, and a support member. The light source part has a light emitting surface to emit light, and the light guide plate has a light incident surface to guide light. The container includes a bottom portion and sidewalls to receive the light source part and the light guide plate. The support member pushes the light guide plate toward the bottom portion to more closely maintain the position of the light incident surface with respect to the light emitting surface. This helps to prevent misalignment between the light exist surface and the light incident surface, maintaining the quantity of light supplied to the light guide plate. | 03-29-2012 |
