Fig. 3 is the pair screen partial schematic diagram of this practical high strength module backlight.
The specific embodiment
Also in conjunction with the accompanying drawings the utility model is further described below by specific embodiment.
Please refer to Fig. 1 to Fig. 3, the utility model relates to a kind of high strength module backlight.Described module backlight generally comprises light source 10, LGP 30, accommodates the framework of light source 10 and LGP 30.In the present embodiment, described light source can be arranged on the LED lamp of described LGP 30 1 sides.And adopt two led light sources.Link to each other with the controller of LCD with interface end 14 by interface end 12 respectively.
Described framework comprises header board 20 and backboard 40.
As first kind of embodiment of the present utility model, be used on single screen module backlight.Specifically, described module backlight further comprises backlight screen 24.The header board 20 corresponding backlight screens 24 of described framework are provided with windows 22.The backboard 40 of described framework is not offered and is windowed.22 be provided with reinforcement 50 around windowing between described backboard 40 and the header board 20.
As second kind of embodiment of the present utility model, be used on the double screen module backlight.Double screen module backlight is a luminous module backlight of two-sided while.Described two-sided larger area main screen backlight and the less backlight secondary screen of area of being respectively.The header board 20 corresponding main screens 24 backlight of described framework are provided with first and window 22.Plate 40 secondary screens 44 corresponding backlight in described back are provided with second and window 42.Window around first between described backboard 40 and the header board 20 and 22 and second window and 42 be provided with reinforcement 50.
The setting of described reinforcement 50 not only can be played the effect of spacing location to the display panels of installing, simultaneously since the strength reinforcing of reinforcement 50 itself whole module backlight.Described reinforcement 50 helps when falling, and guarantees the intensity of module backlight, plays the effect of protection LCD.Optimize the manufacture craft of module backlight, made the production difficulty of module backlight lower.But also can prevent LGP 30 light leaks.
Because the main screen 24 of module backlight and secondary screen 44 two sides all need to leave the groove that display panels is installed, and have backboard 40 difficult making in moulding of less secondary screen 44, so, generally second of described secondary screen 44 backlight is windowed 42 and first the windowing and 22 be arranged to wait greatly of main screen backlight 24.
In the present embodiment, described reinforcement 50 adopts steel disc, and thickness is not to exceed backlight being advisable.And described reinforcement 50 sticks on the described backboard 40 by viscose glue 52.
All be provided with fixed bit (figure does not show) between described reinforcement 50 and header board 20, the backboard 40.It is mutual that described fixed bit can make that reinforcement 50 and header board 20 or backboard 40 produce secure fit between the two, reinforces described module backlight.The structure of described fixed bit helps when falling, and guarantees the intensity of module backlight, plays the effect of protection LCD.
Described fixed bit can adopt following structure: described fixed bit is included in the clearance position that is provided with on header board 20 or the back plate 40 and is arranged on the projection that cooperates with clearance position on the reinforcement 50.
Described fixed bit also can adopt following structure: described fixed bit is included in the projection that is provided with on header board 20 or the back plate 40 and is arranged on the clearance position that cooperates with projection on the reinforcement 50.
Although top detailed description preferred embodiment of the present utility model, but should be understood that many distortion of basic inventive concept clearly, that tell about to those skilled in the art and modification all drop within the spirit and scope of the present invention of claims qualification here.
