20140063789 | BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME - The present invention discloses a backlight module, which includes a light source and an aluminum extrusion. The aluminum extrusion forms at least one thermal chamber. The thermal chamber is a penetrating hollow structure having an opening. The present invention also discloses a liquid crystal display device having the backlight module. Practicing the backlight module of the present invention and the liquid crystal display device using the backlight module allows a channel for air flow to be formed in the interior of the thermal chamber to enhance heat dissipation performance, eliminate the operations of forming a light bar through packaging the light source and an MCPCB and bonding the light bar to the aluminum extrusion, decrease thermal resistance interface, and saves assembling material. | 03-06-2014 |
20140071373 | LIQUID CRYSTAL DISPLAY MODULE - The present invention provides a liquid crystal display module, which includes a backlight module, a mold frame arranged on the backlight module, a liquid crystal display panel arranged on the mold frame, and a bezel arranged on the liquid crystal display panel and fixed to the backlight module. The backlight module includes a backplane. The backplane includes a bottom board and a side board connected to the bottom board. The bezel includes a front wall and a side wall connected to the front wall. The side board forms a projection toward the side wall. The projection forms a threaded hole. The side wall forms a receiving hole corresponding to the projection. The projection is completely received in the receiving hole and secured to the receiving hole by a bolt. | 03-13-2014 |
20140071708 | HOLLOW BACKPLANE AND BACKLIGHT MODULE USING SAME - The present invention provides a hollow backplane and a backlight module using the backplane. The backplane includes a main body and a heat sink mounted on the main body. The main body includes a bottom board and a side board connected to the bottom board. The bottom board forms a plurality of hollow sections. Reinforcement ribs are arranged in the hollow sections. The heat sink is mounted to the bottom board. The bottom board of hollow backplane is made of plastics and forms hollow sections so as to reduce the weight of the backplane. The reinforcement ribs help maintaining the strength of the backplane. With the strength being maintained, the backplane greatly reduces weight, lowers down cost, and is favorable for weight reduction of liquid crystal display device. Further, the backplane has a simple structure and is easy to manufacture, so as to further lower down the manufacture cost. | 03-13-2014 |
20140139779 | Backlight Module and Liquid Crystal Display Device - The present invention discloses a backlight module and a liquid crystal display device. The backlight module comprises a backplane, a heat source, and a heat block mechanism. The heat source is fixed corresponding to the backplane. The heat block mechanism is provided on the way of heat transmission between the backplane and the heat source, which blocks the heat from the heat source transmitted to the backplane. Through the above-described manner, this present invention provides the heat block mechanism on the way of heat transmission between the heat source and the liquid crystal panel, which blocks the heat from the heat source transmitted to the backplane and decreases the uneven brightness resulted from the overheated liquid crystal panel. | 05-22-2014 |
20140184983 | LCD MODULE AND LCD DEVICE - The present disclosure provides a liquid crystal display (LCD) module and an LCD device. The LCD module includes an LCD panel and a backplane. The LCD panel is fixed to the backplane by a magnet. | 07-03-2014 |
20140313773 | LIGHT GUIDE PLATE FIXING STRUCTURE AND A BACKLIGHT MODULE USING THE SAME - A light guide plate fixing structure and a backlight module using the same, comprising a first abutting wall formed at the side edge of the light guide plate, a second abutting wall formed on the backplane, and a constant-force spring arranged between the first abutting wall and the second abutting wall; the constant-force spring has a fixing end and a support end, the fixing end being fixed on the first abutting wall, the support end forming an elastic foot that abuts against the second abutting wall, with the light guide plate being fixed with the help of the elastic force produced by bounce of the constant-force spring after being pre-compressed: when the light guide plate is expanded, it can push the spring away and be released and expanded; when the light guide plate is contracted, rebound of the spring will make the spring move with the light guide plate. | 10-23-2014 |
