20080232120BACKLIGHT ASSEMBLY, DISPLAY MODULE HAVING THE BACKLIGHT ASSEMBLY AND METHOD OF MANUFACTURING THE BACKLIGHT ASSEMBLY - A backlight assembly includes a light source providing light, a mold frame receiving the light source unit and a bottom chassis. The bottom chassis includes a bottom plate, sidewalls extending from the bottom plate and an extension part bent from at least one of the sidewalls and overlapping an adjacent sidewall. The mold frame and the bottom chassis are integrally formed. The extension part overlaps the adjacent sidewall at a corner of the bottom chassis. Thus, the torsional strength of the bottom chassis and a backlight assembly having the bottom chassis is improved. The torsional strength is maintained when a backlight assembly is manufactured.09-25-2008
20080239193LIQUID CRYSTAL DISPLAY MODULE - A liquid crystal display (“LCD”) module includes an LCD panel, a light source unit, a mold frame, a bottom chassis and a driving circuit substrate. The light source unit supplies light to the LCD panel. The mold frame includes a bottom part and sidewall part, and receives the LCD panel and the light source unit. The bottom chassis covers the mold frame and includes a first opening. The driving circuit substrate is disposed between the mold frame and the bottom chassis, and includes a circuit component. The circuit component is formed corresponding to the first opening.10-02-2008
20080273138RECEIVING CONTAINER, METHOD OF MANUFACTURING THE SAME AND LIQUID CRYSTAL DISPLAY HAVING THE SAME - A receiving container, a method of manufacturing the receiving container, and a liquid crystal display having the same are provided. The receiving container includes a mold frame and a strength enhancing means. The mold frame includes a first portion and a second portion connected to the first portion. The strength enhancing means includes a base plate for supporting a lower part of the backlight assembly, and a strength enhancing portion connected to at least a part of the base plate for surrounding at least a part of the second portion.11-06-2008
20080297698LIGHT ILLUMINATING UNIT AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE SAME - A light illuminating unit includes light generating members and a light guiding plate. Each of the light generating members generates light. The light generating members include an LED. The light guiding plate includes a light-incident face onto which the light is incident, a lateral face facing the light-incident face, and a light-exiting face through which the incident light exits. The light-exiting face being configured to connect the light-incident face and the lateral face. An interval between the light-incident face and the lateral face varies in accordance with a position of each of the light generating members. Thus, a number of LEDs decreases, so that an assembly process of the light illuminating unit may be simplified, and manufacturing cost and power consumption thereof may be reduced.12-04-2008
20090103326DISPLAY DEVICE HAVING LIGHT GUIDE UNIT - A light guide unit for a point light source includes a light incident portion, a first reflecting portion and a second reflecting portion. The light emitted from the point light source enters to the light incident portion. The light incident portion includes an optical pattern diffusing an incident light corresponding to the point light source. The first reflecting portion reflects a first light of the incident light. The second reflecting portion roundly connects the first reflecting portion to the light incident portion and reflects a second light of the incident light.04-23-2009
20090180051DISPLAY DEVICE - A display device including a case including a front case and a rear case, a main display panel and a sub display panel disposed inside the case, a protective member disposed on a front surface of the main display panel and protecting the main display panel, and a support frame disposed inside the case and supporting both the display panel and the protective member. The support frame includes a first support part contacting a lower surface of the main display panel and a second support part supporting a lower surface of the protective member.07-16-2009
20100172155LIGHT GUIDE UNIT FOR POINT LIGHT SOURCE, BACKLIGHT ASSEMBLY HAVING THE LIGHT GUIDE UNIT AND DISPLAY DEVICE HAVING THE SAME - A light guide unit for a point light source includes a light incident portion, a first reflecting portion and a second reflecting portion. The light emitted from the point light source enters to the light incident portion. The light incident portion includes an optical pattern diffusing an incident light corresponding to the point light source. The first reflecting portion reflects a first light of the incident light. The second reflecting portion roundly connects the first reflecting portion to the light incident portion and reflects a second light of the incident light.07-08-2010

20110001731ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE - An organic light emitting diode display device capable of achieving a considerable reduction in power consumption by generating a drive signal only for a period, in which the drive signal is actually required, is disclosed. The organic light emitting diode display device includes a DC-DC converter including a switching element to generate a drive signal by controlling an input voltage under a control of a logic, and a driver to supply, to pixels, the drive signal generated from the DC-DC converter in accordance with a timing. The logic includes an AND circuit to AND a control signal for drive signal generation and an output control signal maintained at a logic-high voltage only for a period in which the drive signal is to be supplied, and to supply a result of the ANDing operation.01-06-2011
