Description
Technical field
The utility model belongs to liquid crystal display and lighting system technical field, and in particular to a kind of backlight assembly.
Background technology
Backlight is to provide the light source of panel of LCD, with continuing to develop for lcd technology, liquid crystal display
The application field of device particularly colour liquid crystal display device is also constantly being widened, and liquid crystal display is the display device of non-luminescent,
The function of display must be can be only achieved with backlight, the quality of backlight performance is except that can directly affect the imaging of liquid crystal display
Outside quality, the cost of backlight accounts for the 30-50% of LCD MODULE, and the electric power consumed more accounts for the 75% of module, fine, big
The liquid crystal display of size must have high performance backlight technology matched.
Backlight mainly has tri- kinds of type of backlight of EL, CCFL and LED at present, is then divided into side according to distribution of light sources position difference
Light formula and straight-down negative, with continuing to develop for lcd technology, the high performance of backlight technology, such as high brightness, low cost
Change, power reducing, lightening etc., the main development direction as backlight.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of luminous uniform, brightness height, the backlight assembly of light and thin type.
In order to realize above goal of the invention, the utility model provides a kind of backlight assembly, successively including diffusion sheet, lead
Tabula rasa reflector plate, the light guide plate side, which is provided with the outside of light source, the light source, is provided with light source reflecting plate, the light source reflection
The section of plate is U-shaped, one end connection reflector plate, the other end by two-sided gemel connection light guide plate close to light source one end edge；Institute
It is wedge shape to state light guide plate, and the side thickness close to light source is more than the side away from light source；The reflector plate close to light guide plate one
Face is covered with some reflection bars, and reflection bar is parallel with the side on reflector plate close to light source, and the reflection bar away from light source one end sum is wider than
Reflection bar close to light source one end.
As it is of the present utility model it is a kind of improve, the distance between the reflection bar away from light source one end and reflection bar, which are wider than, to be leaned on
The distance between reflection bar and reflection bar of close to sources one end.
As a kind of improvement of the present utility model, the reflection bar is alloy bar.
As a kind of improvement of the present utility model, in addition to upper brightening piece and lower brightening piece, lower brightening piece is overlying on diffusion sheet
On, upper brightening piece is overlying on lower brightening piece.
As a kind of improvement of the present utility model, the thickness of the reflection bar is 0.002mm.
The utility model discloses a kind of backlight assembly, beneficial effect is that luminous uniform, brightness is high and frivolous, light effect
Rate is high.
Brief description of the drawings
Fig. 1 is a kind of structural representation of backlight assembly of the utility model.
Fig. 2 is the structural representation of reflector.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of backlight assembly shown in Fig. 1, Fig. 2, successively including diffusion sheet 1, light guide plate 2 and reflector plate 3, the leaded light
The side of plate 2 is provided with light source 4, and the outside of light source 4 is provided with light source reflecting plate 5, the section of the light source reflecting plate 5 be it is U-shaped,
One end connect reflector plate 3, the other end by two-sided gemel connection light guide plate close to light source one end edge；The light guide plate 2 is wedge
Shape, the side thickness close to light source 4 is more than the side away from light source 4；If the reflector plate 3 is covered with close to the one side of light guide plate 2
Dry reflection bar 6, reflection bar 6 is parallel with the side on reflector plate close to light source, and the reflection bar away from the one end of light source 4 is wider than close to light source
The reflection bar of one end.More light is reflected into light guide plate, to increase the light extraction efficiency of exiting surface, improve brightness.
As it is of the present utility model it is a kind of improve, the distance between the reflection bar away from the one end of light source 4 and reflection bar are wider than
The distance between reflection bar and reflection bar close to light source one end.Using this design, light extraction is more uniformly distributed, and reduces bright spot.
As a kind of improvement of the present utility model, the reflection bar 6 is alloy bar, preferably alumal bar.
As a kind of improvement of the present utility model, in addition to upper brightening piece 7 and lower brightening piece 8, lower brightening piece 8 is overlying on diffusion
On piece 1, upper brightening piece 7 is overlying on lower brightening piece 8.Uniform in light emission is ensured using this design, increases brightness.
As a kind of improvement of the present utility model, the thickness of the reflection bar is 0.002mm.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this reality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in of the present utility model
Within protection domain.
