A backlight assembly includes a plurality of lamps, a receiving container and a conductive member. Each of the lamps includes a lamp body, a first electrode part disposed at a first end portion of the lamp body and a second electrode part disposed at a second end portion of the lamp body, the second end portion being opposite to the first end portion. The receiving container includes a bottom plate on which the lamps are disposed and a sidewall disposed at edge portions of the bottom plate to define a receiving space. The receiving container has a plurality of grounding portions formed on the bottom plate or the sidewalls. The conductive member electrically connects the second electrode part to one of the grounding portions.

Disclosed is an LCD apparatus including a receiving container for receiving a light guide plate and a lamp assembly, a first chassis for fixing the light guide plate and an LCD panel, and a second chassis for fixing the first chassis and the LCD panel. The receiving container and the first and second chassis are made of metal material so that the LCD apparatus may have reduced size and weight.

Liquid crystal display apparatus

A lamp fixing unit capable of simplifying the manufacture of a backlight assembly by eliminating the need for manual procedures is presented. The lamp fixing unit includes a fixing member and a lamp holder. The fixing member includes a fixing body and at least one receiving portion. The lamp holder includes a holder body and a conductive socket. The holder body includes a board insertion portion, a power supply member, and a lamp fixing member. Thus, the power supply member may be easily coupled to and uncoupled from the lamp holder, and the lamp may be easily grounded.

A lamp holder includes a holder body and a power connector. A lamp guide groove is formed on an upper portion of the holder body. An inverter insertion groove is formed on a lower portion of the holder body, and a power supply board is slidably coupled to the inverter insertion groove. The power connector includes a first portion exposed to the inverter insertion groove, and a second portion disposed adjacent to the lamp guide groove. The lamp holder fixed to a fixing groove of an insulation plate is inserted into an opening formed through a bottom plate of a receiving container. Thus, a backlight assembly having the lamp holder may be easily assembled and repaired.

Backlight assembly and liquid crystal display thereof

A lamp assembly, light supplying module and LCD device using the same are provided. The LCD device includes the light-supplying module for generating a first light, a light distribution-changing module for receiving the first light and changing the optical characteristics of the first light to output a second light, and a display module for receiving the second light having improved optical characteristics, the light distribution-changing module being coupled to the light-supplying module by means of a first engaging member, the display module being coupled in the light distribution-changing module by means of a second engaging member, and the display module, light distribution-changing module and light-supplying module being coupled to each other by means of a third engaging member. Therefore, each component of the LCD device having above structure is easily separated, replaced and easily repaired.

A backlight assembly includes a receiving container, a first side mold, a printed circuit board and a plurality of lamps. The first side mold is on the side of the receiving container. The printed circuit board is combined with the first side mold, the printed circuit board including a plurality of conductive clips and a power supply line assembly for transmitting a lamp driving electric power. The lamps are combined with the conductive clips to generate light based on the lamp driving electric power. The power supply line assembly includes a first conductive line electrically connected to a subgroup of conductive clips and a second conductive line electrically connected to the other conductive clips. The first and second conductive lines are supplied with the lamp driving electric powers that have reverse phases to each other. Therefore, noise is decreased according to its waterfall curve to improve an image display quality.

Backlight assembly and liquid crystal display device with reduced noise

A backlight assembly with excellent light efficiency and a display device provided with the backlight assembly is provided where the backlight assembly includes a plurality of light sources longitudinally arranged in parallel to each other, and a fixing member receiving the plurality of light sources. When a display area, formed by light emitted from the plurality of light sources, is divided by the plurality of light sources into a plurality of display area sections, an average area of the display area sections between light sources adjacent to each other is less than or equal to an area of a display area section between an edge of the display area and the light source most adjacent thereto.

Backlight assembly with excellent light efficiency and display device having the same

A receptacle assembly that receives a back light assembly and a display unit of a liquid crystal display device is disclosed. The receptacle assembly for receiving the back light assembly comprises a first receptacle module and a second receptacle module engaged with the rear surface of the first receptacle module to support the first receptacle module. The first receptacle module and the second receptacle module are formed of plastic and metal respectively. Therefore, the distortion that can be generated by the exterior impact and the vibration and the deflection due to the heat can be prevented. Further, the productivity is improved by simplifying the engaging structure of the receptacle assembly, and the size stability is improved.

Liquid crystal display device with a structure receiving a back light assembly and a display unit

In the packaging of an LCD module within a small and lightweight case, the case comprising a front case and a rear case, a recess with a predetermined depth, formed at the edge of the bottom side of the LCD module, is combined with a boss formed at the case, and a recess with a predetermined depth, formed at the edge of its surface, is fastened to a fastening means for securing the LCD module, thereby minimizing the difference between the areas of the LCD module and the case and further reducing the number of processes required for combining the LCD module with the case. In addition, the recess formed at the surface edge of the LCD module is combined with a fastening hook formed at the rear case so that the LCD module can be secured to the rear case and to the front case without any separate fastening member such as a stud or insert.
