The specific embodiment
The backlight module that the utility model provides and display unit reach by reference to the accompanying drawings embodiment and are described in detail as follows:
As shown in Figure 3, as the first embodiment of the present utility model, the backlight module in the present embodiment comprises end reflector plate 5 and backboard 4, and reflector plate of the described end 5 is positioned at backboard 4 tops, described backlight module also comprises elastic patch 12, and described elastic patch 12 is attached on the reflector plate of the described end 5.
Preferably, above-mentioned elastic patch 12 is attached at least one angle of reflector plate of the described end 5.
Further preferably, described elastic patch 12 is attached on four angles of reflector plate of the described end 5.
As shown in Figure 3, backlight module according to the utility model the first embodiment comprises: light source 2, LGP 3, backboard 4, end reflector plate 5, optical film material 6, framework 7, lamp batten 8, radiator 9, elastic patch 12 etc., light source 2 is arranged at least one side of LGP 3, end reflector plate 5 is arranged on the one side of LGP 3, optical film material 6 is arranged on the LGP 3 on the face opposite with end reflector plate 5, light source 2 is fixed on the lamp batten 8 of LGP 3 at least one sides, radiator 9 is around in outside lamp batten 8 and the end reflector plate 5, and be fixed on the framework 7, backboard 4 is around in outside framework 7 and the radiator 9, and elastic patch 12 is attached on four angles of end reflector plate 5.By attaching this elastic patch 12 in the intensity that has increased end reflector plate 5, because the elastic stress of elastic patch 12, it can make end reflector plate 5 keep smooth, make itself and LGP 3 keep good contact, eliminate the air gap, reduce reflecting the extraordinary light that is transmitted on the display floater, avoid display frame bright band to occur.Except four angles of end reflector plate 5, this elastic patch of Anywhere attaching that can on end reflector plate 5, may bend according to actual needs.
