Description
Technical field
The utility model relates to display screen technology fields, and in particular to the backlight of a kind of side entering type light source and quantum dot leaded light
Source structure.
Background technique
Backlight module is one of the key part and component of panel of LCD, and function is well-off brightness and divides
The uniform light source of cloth, enables liquid crystal display normally to show image.Backlight module is mainly by backlight, liquid crystal display panel, glass cover
The composition such as plate, and conventional backlight, are mainly made of light source, light guide plate, reflector plate, optical diaphragm etc..It is issued by light source
Light passes through light guide plate, optical diaphragm, eventually arrives at liquid crystal display panel, provides light source to liquid crystal display panel.Its action principle is: by light source
Over the qds, the light that light source issues is converted to white light to the light direct irradiation of sending by quantum dot.The disadvantage is that: light source directly shines
It penetrates over the qds, since light source is generally side entering type light source, the intensity that light source is radiated at different location quantum dot is different, causes
The intensity of emergent light is uneven, influences image quality.
Utility model content
In view of the above problems, the utility model provides, a kind of structure is simple, the uniform side entering type light source of exiting light beam intensity and
The back light source structure of quantum dot leaded light.
To achieve the above object, the utility model solves by the following technical programs:
A kind of back light source structure of side entering type light source and quantum dot leaded light, including glass light guide plate, lead positioned at the glass
The light source of tabula rasa side, the light passing layer on the upside of the glass light guide plate, the quanta point material on the upside of the light passing layer
Layer and the protective layer on the upside of the quanta point material layer, the edge of the quanta point material layer are coated with a circle
Sealant.
Specifically, the glass light guide plate is equipped with several sites far from the one side of the light passing layer.
Specifically, the light source is blue led.
Specifically, the light passing layer is transparent plastic material, refractive index 1.05-1.15.
Specifically, the protective layer is ultra-clear glasses plate.
The beneficial effects of the utility model are:
First, the back light source structure structure of the utility model is simple, uses side entering type blue led as light source, quantum
The blue light that light source issues is converted to white light by point material layer, and structure is simple, the high conversion efficiency of light；
Second, one layer of light passing layer is also added between glass light guide plate and quanta point material layer, light passing layer is by refractive index
Light for 1.05-1.15 transparent plastic material composition, site reflection passes through light passing layer, and light is made respectively to scattering, to improve emergent light
Dispersion effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of a kind of side entering type light source of the utility model and the back light source structure of quantum dot leaded light.
Appended drawing reference are as follows: glass light guide plate 1, site 11, light source 2, light passing layer 3, quanta point material layer 4, protective layer 5, close
Sealing 6.
Specific embodiment
The utility model is described in further detail below with reference to embodiment and attached drawing, but the implementation of the utility model
Mode is without being limited thereto.
As shown in Figure 1:
A kind of back light source structure of side entering type light source and quantum dot leaded light, including glass light guide plate 1, it is located at glass light guide plate
The light source 2 of 1 side, the light passing layer 3 positioned at the upside of glass light guide plate 1, the quanta point material layer 4 positioned at 3 upside of light passing layer and
Protective layer 5 positioned at 4 upside of quanta point material layer, quanta point material layer 4 is exposed to be oxidized easily in air, in quantum dot material
The edge of the bed of material 4 is coated with a circle sealant 6, and sealant 6 makes quanta point material layer 4 and air exclusion, plays protection and makees
With.
Preferably, glass light guide plate 1 is equipped with several sites 11 far from the one side of light passing layer 3, and the light that light source 2 issues reaches net
Parallel incident light is converted to upward light by point 11, site 11, reaches light passing layer 3.
Preferably, for the setting of light source 2 in 1 side of glass light guide plate and as side entering type light source 2, light source 2 is blue led.
Preferably, light passing layer 3 is transparent plastic material, and in order to keep the light by light passing layer 3 more uniform, light passing layer 3 is answered
Have the function of making incident light respectively to scattering, in order to realize that this function, refractive index are set as 1.05-1.15.
Preferably, protective layer 5 is used to protect the 4 not oxidation by air of quantum dot material layer, meanwhile, in order to not influence backlight
The light-out effect of structure, protective layer 5 are ultra-clear glasses plate.
A kind of embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
