Abstract
The invention discloses a backlight module, which comprises a frame, a liquid crystal panel and an LED (Light Emitting Diode) light source. The frame comprises a rear back plate, a first side plate and a second side plate. One ends of the first side plate and the second side plate are integrally connected with the rear back plate. The other ends of the first side plate and the second side plate are provided with a plastic connecting frame. The liquid crystal panel is fixedly connected with the other ends of the first side plate and the second side plate through the plastic connecting frame. LED light sources are installed on the inner faces of the first side plate and the second side plate. A light guide plate is arranged between the LED light sources. The invention has the benefits that through the light guide plate and the back plate, the weight of the backlight module is greatly reduced and the cost is greatly lowered when light efficiency is not changed. Compared with current backlight modules, the maximum weight can be reduced for 30%, and the cost is lowered for more than 20%. Meanwhile, the light utilization ratio is improved, the light loss is reduced, and the energy source is saved.
Description
Technical field
Present invention is specifically related to a kind of backlight module.
Background technology
Liquid crystal indicator (Liquid Crystal Display is called for short LCD) is display, especially thin-film transistor LCD device commonly used at present.Because liquid crystal layer itself there is no luminous function, so need to show to realize image for LCD provides light source.In through mode LCD, adopt backlight module to come to provide for liquid crystal layer the light source of a high brightness and illuminance distribution.
In the prior art LCD backlight module, generally comprise optical film, LGP (light guide plate, abbreviation LGP), fluorescent tube, lampshade and backlight lamp reflecting plate, optical film generally includes the optical thin films such as diffusion sheet, prismatic lens, lower diffusion sheet, can select as the case may be, side at LGP is equiped with fluorescent tube and lampshade, and backlight lamp reflecting plate is arranged on the below of fluorescent tube and LGP.Wherein fluorescent tube is main luminous component, and fluorescent tube launches light into LGP, then launches light in the liquid crystal panel of optical film top by LGP again.
Above-mentioned backlight module adopts the side light source mode, and have at least following defective: the LGP of employing is general
Be cuboid, weight is larger, makes LCD not light; Owing to need to adopt lampshade to improve optical efficiency, make
The cost of LCD increases; Adopt backlight lamp reflecting plate or reflectance coating etc. not only to increase cost but also increased weight.
Summary of the invention
The object of the present invention is to provide a kind of LED module, by existing LGP and back board structure are improved, the deficiency such as overcome that cost in the conventional art is high, weight is large and not light, thus realize purpose of the present invention.
Technical problem solved by the invention can realize by the following technical solutions:
Backlight module, it comprises framework, liquid crystal panel and led light source, described framework comprises postnotum, the first side plate and the second side plate, described the first side plate be connected an end of side plate and be connected with the postnotum one, the other end of the first side plate and the second side plate is provided with the plastic cement connection box, described liquid crystal panel is connected and fixed by the other end of plastic cement connection box and the first side plate and the second side plate, the medial surface of described the first side plate and the second side plate all is equipped with a led light source by installing plate, and a LGP is installed between the described led light source.
In one embodiment of the invention, the center line line of described led light source is lower than the center line of LGP, and the width of described led light source is greater than the thickness of LGP.
In one embodiment of the invention, described framework is hatch frame, and the postnotum, the first side plate and the second side plate that form framework all adopt polyvinyl chloride to make.
Beneficial effect of the present invention is: by adopting novel LGP and back board structure, in the constant situation of optical efficiency, the weight of backlight module alleviates greatly, and cost significantly reduces.With respect to existing backlight module, maximum weight can alleviate 30%, and cost has improved the light utilization ratio more than 20% simultaneously, reduces fiber-loss, has saved the energy.
Description of drawings
Fig. 1 is the structural representation of backlight module of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Shown in Fig. 1, backlight module of the present invention, it comprises framework, liquid crystal panel 15 and led light source, described framework comprises postnotum 13, the first side plate and the second side plate, described the first side plate be connected an end of side plate and be connected one with postnotum and connect, the other end of the first side plate and the second side plate is provided with the plastic cement connection box, described liquid crystal panel is connected and fixed by the other end of plastic cement connection box 14 and the first side plate and the second side plate, the medial surface of described the first side plate and the second side plate all is equipped with a led light source 121 by installing plate 12, and a LGP 11 is installed between the described led light source.
In an embodiment of the present invention, in order to reach better light reflecting effect, the center line line of described led light source is lower than the center line of LGP, and the width of described led light source is greater than the thickness of LGP.
Especially it is pointed out that described framework is hatch frame in order to alleviate the weight of backlight module, the postnotum, the first side plate and the second side plate that form framework all adopt polyvinyl chloride to make.
The present invention is by adopting novel LGP and back board structure, and in the constant situation of optical efficiency, the weight of backlight module alleviates greatly, and cost significantly reduces.With respect to existing backlight module, maximum weight can alleviate 30%, and cost has improved the light utilization ratio more than 20% simultaneously, reduces fiber-loss, has saved the energy.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
