For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of liquid crystal display, comprise a LCD screen, a control circuit board and a backlight module, described backlight module comprises: a light guide plate, described light guide plate has a relative first surface, one second and one side connecting described first surface and second, and described light guide plate is at least formed with sheet feeding type at described first surface; One light source, has an illuminating part and two power pins, and the illuminating part of described light source is movably connected on the first surface of described light guide plate; One anti-dazzling screen, is located at the first surface of described light guide plate; And at least one reflector plate, be located at the side of light guide plate; Described LCD screen is located at second of described light guide plate, and described control circuit board is located at the first surface of described light guide plate, and makes described anti-dazzling screen between described control circuit board and light guide plate.
The first surface of described light guide plate is formed with an assembly hole, and described light source active plugs and is fixed on described assembly hole.
Described sheet feeding type comprises multiple concave convex texture.
Each described concave convex texture is in the first surface being equidistantly distributed in described light guide plate.
Also comprise an equal mating plate, described equal mating plate is located at second of described light guide plate.
Described sheet feeding type part is distributed in first surface, and assembly hole is opened in one end of non-sheet feeding type.
The beneficial effect of technique scheme of the present utility model is as follows:
Liquid crystal display of the present utility model, owing to adopting detachable design between light source and light guide plate, when light source failure or when damaging, user need only be detached light guide plate, then the assembly hole of the new light source newly purchased and light guide plate is mutually combined and can be reused; In addition, the utility model can provide light collecting effect good and uniform light, to promote brilliant degree and the brightness effects of LCD screen the best; Its structure is simplified, and can be applied in small size structure, and separately can design along with the dimensions of control circuit board, to be useful in multiple large and small dimensions.

Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1 to Figure 3, the utility model embodiment provides a kind of liquid crystal display, comprises a backlight module, and described backlight module comprises light guide plate 1, light source 2, anti-dazzling screen 3 and a reflector plate 4.
Described light guide plate 1 has relative first surface 11,1 second face 12 and vertically connects first surface, the peripheral side of second, and the first surface 11 of described light guide plate 1 is formed with sheet feeding type 13 and an assembly hole 14; Described sheet feeding type 13 comprises multiple concave convex texture 131, the dimpled grain of each described concave convex texture 131, the predetermined depth that caves in from the first surface 11 of described light guide plate 1 toward the second direction, face 12 and being formed, each described concave convex texture 131 is in the first surface 11 being equidistantly distributed in described light guide plate 1.
Described light source 2 is removably located at the first surface 11 of described light guide plate 1, more particularly, is not provided with in the assembly hole 14 of sheet feeding type one end described in described light source 2 is inserted in; Wherein said light source 2 is located at one end place of contiguous described light guide plate 1, described light source 2 has illuminating part 21 and two power pins 22, the illuminating part of the present embodiment is a light emitting diode, described illuminating part 21 is located at towards the larger side of light guide plate 1 volume and is submerged in light guide plate 1 with light source 2, and each described power pin 22 is electrically connected with described illuminating part 21 and stretches out in the first surface 11 of described light guide plate 1.
The first surface 11 of described light guide plate 1 is located at by described anti-dazzling screen 3, light barrier emitted by side from the contiguous described anti-dazzling screen 3 of light guide plate 1 can be reflected back in light guide plate 1 by described anti-dazzling screen 3, to promote the service efficiency of light, light is avoided to do invalid projection to the first surface 11 of light guide plate 1.Set up an equal mating plate 3a in the second face 12 of light guide plate 1 in addition, object be to make light source evenly, soft.
Described reflector plate 4 is that closed is around described light guide plate 1; Described reflector plate 4 can will return in light guide plate 1 toward the light reflection emitted by surrounding from light guide plate 1, to promote the service efficiency of light and to promote light collecting effect, avoid light to do invalid projection by the surrounding side of light guide plate 1, reach the effect stopping invalid projection source.
As shown in Figure 4 and Figure 5, described liquid crystal display is except comprising described backlight module, also comprise LCD screen 5 and a control circuit board 6, described LCD screen 5 is located at the second face 12 of described light guide plate 1, and carry out accurate consistency from top to bottom by the fin of second and light guide plate, described control circuit board 6 is located at the first surface 11 of described light guide plate 1, and makes described anti-dazzling screen 3 between described control circuit board 6 and light guide plate 1.
When light source 2 produce light enter light guide plate 1 time, described light can be subject to the stop of anti-dazzling screen 3 and reflector plate 4, leaked by the first surface of light guide plate and peripheral side to prevent light, and allow light concentrate entirely on the first surface 11 of light guide plate, and via the sheet feeding type 13 of concave convex texture that light guide plate 1 first surface 11 is formed, light is made to produce multiple refraction by sheet feeding type surface and then to produce best light harvesting, light-out effect, also mutually can arrange in pairs or groups via the equal mating plate of sheet feeding type surface refraction and second simultaneously, make the more even of the distribution of light of output and brightness also comparatively relaxes, splendid identification light quality can be provided to LCD screen 5.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
