The present invention discloses a chip heat dissipation structure and a liquid crystal display device, and the chip heat dissipation structure includes: a chip contact end and a backplate contact end. The chip heat dissipation structure is made of thermal conductive material. The backplate is a backplate on a bottom of a backlight module in the liquid crystal display device. The present invention by conducting heat generated by the chip to the backplate lowers the increased temperature of the chip to solve the issue the heated surface of the liquid crystal display device.

A backlight module and a display having the same are provided. The backlight module includes a front bezel, a back cover, and a light source. The back cover is disposed opposite to the front bezel. The back cover includes a body and one or more heat dissipation elements. The body has one or more openings corresponding to one or more heat sources. The one or more heat dissipation elements are disposed in the one or more openings, respectively. The light source is disposed between the front bezel and the back cover.

The backlight device included in the display apparatus is provided with: a light guide plate, a front chassis (pressing member) disposed at the front side of the light guide plate; and a heat sink (supporting member) having a plate-shaped connecting part (connecting plate) disposed at the side of the light guide plate, to be connected with other members. A through hole is formed in the connecting part, and a nut, which is necessary for connecting a bezel and the front chassis with a screw, is press-fitted into the through hole. A portion of the front side end of the connecting part, which is closest to a through hole, is a recessed part. Even if the front side end of the connecting part is deformed by the press-fitting of the nut into the through hole, the recessed part counteracts the deformation, and the connecting part does not interfere with the front chassis. Therefore, positional deviation of the front chassis and the light guide plate does not occur.

Provided is a light source device which includes a light guide plate for emitting light entered through one side surface from a front surface thereof, a light source disposed opposing the one side surface of the light guide plate, a rear housing body for housing the light guide plate and the light source, and a heat spreader.

Disclosed herein is a display apparatus having a cooling path provided to enhance cooling efficiency. The display apparatus includes a display panel configured to display images; a light source configured to radiate light toward the display panel; a bottom chassis disposed in rear of the light source; a case provided in rear of the bottom chassis; a circulative cooling path provided as to have air circulated surroundings of the bottom chassis.

A backlight unit A backlight unit comprises first and second glass substrates, a resin layer between the first and second glass substrates, light sources on the first and second glass substrates, first and second transistors on the first and second glass substrates and electrically connected with the light sources, and spaced apart from each other, first conductive layers on a portion of an upper surface of the first glass substrate, second conductive layers on a portion of an upper surface of the second glass substrate, and third conductive layers on the first glass substrate, the second glass substrate, and the resin layer, wherein one of the third conductive layers is electrically connected with one of the first conductive layers and one of the second conductive layers and is on a portion of an upper surface of the resin layer.

Exemplary embodiments include an electronic display assembly for back to back electronic image assemblies. A first closed gaseous loop may encircle the first electronic image assembly while a second closed gaseous loop may encircle the second electronic image assembly. A heat exchanger is preferably positioned within the path of the first and second closed gaseous loop along with an open loop of ambient air. A circulating fan(s) may be used to force circulating gas around the closed gaseous loops. An open loop fan may be used to force ambient air through the heat exchanger and through an optional channel behind each electronic image assembly.

An electrical connection assembly for a directional display comprising a directional backlight may include stack of flat connectors and a strip comprising an end portion with an array of light sources and a base portion with an array of connectors. The end portion and base portion may be shaped so that the base portion extends outwardly from the end portion. Light sources of the directional display may be individually addressable by means of a highly compact arrangement of connections, achieving low thickness and small bezel width.

The invention discloses an edge type backlight module. The edge type backlight module includes: a back frame having at least one sidewall and at least one bottom plate; a light guide plate disposed on the bottom plate and having a light incident side surface, wherein the light incident side surface is opposite to the sidewall; and a plurality of first backlight sources and a plurality of second backlight sources, wherein the first backlight sources are disposed on the sidewall, the second backlight sources are disposed on the bottom plate and against the sidewall, the first backlight sources and the second backlight sources are alternately disposed, the first backlight sources include a plurality of first LED lamps, and the second backlight sources include a plurality of second LED lamps. The invention also discloses a liquid crystal display device having the edge type backlight module. The COF of the invention is disposed on a portion of the second backlight sources with a lower temperature, so that the COF is in a lower temperature condition, thereby improving its reliability.

The invention relates to a backlighting device (14), particularly for head-up display. Said device includes: at least one light-emitting diode (16), emitting light beams; an optical system (20) for shaping light beams; and a light diffuser (22), receiving the shaped light beams and said diffuser also comprises a heat sink (18) formed of at least two parts including a base plate (50) and at least one strip (52) that is attached onto said base plate. The strip comprises at least one fold (90) for forming at least one cooling fin (80) and at least one area (60) intended for thermal contact with said base plate (50).
