Description
Technical field
It the utility model is related to field of backlights, more particularly to a kind of backlight and liquid crystal display die set.
Background technology
As shown in figure 1, be a kind of existing backlight, including glue frame 1 ', the light guide plate 2 ' that is arranged in glue frame 1 ', glue frame
1 ' bottom surface is provided with lamp bar groove 11 ' before the incidence surface of light guide plate 2 ', and lamp bar 3 ' is fixed in lamp bar groove 11 '；Because of lamp bar groove
11 ' the reason for, the part light-emitting area of lamp bar 3 ' can be less than the back side of light guide plate 2 ', cause some light from light guide plate 2 ' and reflection
Gap between film 4 ' is directly injected in VA areas, the light for the micro-structural processing that this part is not passed through on the incidence surface of light guide plate 2 '
Line Hui VA areas form hot spot, influence display effect.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of backlight and liquid crystal display die set.Should
The light of backlight will not form hot spot in VA areas, have good display effect.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of backlight, including glue frame, the light guide plate that is arranged in the glue frame, the bottom surface of the glue frame is in the leaded light
Lamp bar groove is provided with before the incidence surface of plate, is provided with lamp bar in the lamp bar groove, the bottom surface of the light guide plate and the glue frame it
Between be provided with reflector plate；It is gluing by the first shading in one end close to the lamp bar between the reflector plate and the light guide plate
Stick together.
Further, hidden between the bottom surface of the reflector plate and the glue frame close to one end of the lamp bar by second
Optical cement is pasted together.
Further, first shading glue or the second shading glue are black glue.
Further, an at least optical film is provided with the exiting surface of the light guide plate.
Further, the lamp bar includes wiring board and at least luminescent device being arranged on the wiring board.
Further, the lamp bar by dispensing hydropexis in the lamp bar groove.
Further, it is provided with anti-dazzling screen on the glue frame.
A kind of liquid crystal display die set, including above-mentioned backlight.
The utility model has the advantages that：The backlight is before the lamp bar using described in the first shading glue
Light guide plate and reflector plate, to stop and absorb light, the gap that can prevent light from entering between the light guide plate and lamp bar
It is interior, to reduce the hot spot in VA areas, improve its display effect.
Brief description of the drawings
Fig. 1 is the schematic diagram of existing backlight；
Fig. 2 is the schematic diagram of backlight provided by the utility model；
Fig. 3 is enlarged drawing at the A of the backlight shown in Fig. 2.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment one
As shown in Figures 2 and 3, a kind of backlight, including glue frame 1, the light guide plate 2 that is arranged in the glue frame 1, the glue frame
1 bottom surface is provided with lamp bar groove 11 before the incidence surface of the light guide plate 2, and lamp bar 3 is provided with the lamp bar groove 11, described to lead
Reflector plate 4 is provided between the bottom surface of tabula rasa 2 and the glue frame 1；Close to institute between the reflector plate 4 and the light guide plate 2
The one end for stating lamp bar 3 is pasted together by the first shading glue 7.
The backlight pastes the light guide plate 2 and reflector plate 4 before the lamp bar 3 using the first shading glue 7, with stop and
Absorb light, can prevent light from entering in the gap between the light guide plate 2 and lamp bar 3, thus will not VA areas hot spot,
Improve its display effect.
Preferably, second is passed through in one end close to the lamp bar 3 between the bottom surface of the reflector plate 4 and the glue frame 1
Shading glue 8 is pasted together.
The shading glue 8 of first shading glue 7 and/or second is preferably but not limited to black glue.
