Description
Technical field
The utility model is related to a kind of light guide plate, especially a kind of Double-color integrated injection quantum dot light guide plate.
Background technology
Backlight module is used to provide area source for liquid crystal display panel.Light source and light guide plate are generally included in backlight module,
The light sent from light source is entered into light guide plate into the incidence surface of the light guide plate, via after the diffusion of light guide plate by leading
The exiting surface outgoing of tabula rasa, so that for liquid crystal display panel provides area source.Therefore, light guide plate is the performance for influenceing backlight module
Vital core component, and because technology of quantum dots development so that its turn into people research focus.
As CN104849910 discloses a kind of quantum dot backlight module, it sets a quantum dot in the incident side of light guide plate
Layer.But there is different refractivity between the incidence surface and quantum dot layer of light guide plate, this can cause optical energy loss.
Utility model content
The utility model aims to provide a kind of Double-color integrated injection quantum dot light guide plate, to overcome in the prior art because of leaded light
There is a problem of different refractivity and cause optical energy loss between the incidence surface and quantum dot layer of plate.
The technical solution of the utility model is as follows：
A kind of Double-color integrated is molded quantum dot light guide plate, and at least one side of the light guide plate is incident for making light
Incidence surface, the upper and lower plate face of the light guide plate is respectively the reflecting surface of the exiting surface and reflection light for making uniform light outgoing,
The light guide plate integrated injection molding, including the red and green color quantum dot region with the incidence surface and described red green pair of adjoining
The light directing site area of color quantum dot region, the site in the light directing site area is evenly distributed on the exiting surface.
Further, the lateral thickness of the red and green color quantum dot region is 1-5mm.
Further, the site be shaped as it is circular, oval or square.
Further, the light guide plate is by polymethacrylates or makrolon and red and green color quantum dot integrated injection molding
Shaping.
The utility model uses the above-mentioned technical proposal, specific beneficial effect to be：The utility model using quantum dot region with
Site area integrated injection molding, quantum dot region does not exist the different interface of refractive index from site area, therefore light efficiency is maximum
Change, optical energy loss very little, and colour gamut white light high can be obtained.
Brief description of the drawings
Fig. 1 is the side view of one embodiment of the present utility model；
Fig. 2 is the front view of the embodiment shown in Fig. 1.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model is disclosed
A part for appearance, it is mainly used to illustrate embodiment, and running of the associated description of specification to explain embodiment can be coordinated former
Reason.Coordinate and refer to these contents, those of ordinary skill in the art will be understood that other possible implementation methods and this practicality are new
The advantage of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
With reference to Fig. 1 and 2, light guide plate 1 is described in detail.The generally rectangular shape of light guide plate 1, including it is incident for making light
Incidence surface 101, reflection light reflecting surface 102 and make the exiting surface 103 of uniform light outgoing.Wherein, incidence surface 101 is to lead
The side of tabula rasa 1, exiting surface 103 is parallel with reflecting surface 102, is respectively the upper and lower plate face of light guide plate 1.Light guide plate 1 is one
Injection moulding, including the red and green color quantum dot region 104 with incidence surface 101 and the adjacent red and green color quantum dot region
104 light directing site area 105.Preferably, the lateral thickness of red and green color quantum dot region 104 is 1-5mm.The thickness both can guarantee that
Good light-out effect, again will not be to the effective range of influence light guide zone.Site 106 in light directing site area 105 is uniformly distributed
On exiting surface 103.The shape of site 106 can be circular, oval or square etc..It is unrestrained that site 106 can occur light
Penetrate, so that light extraction is evenly.
Preferably, light guide plate 1 is by polymethacrylates or makrolon and red and green color quantum dot integrated injection molding.
Therefore, quantum dot region does not exist the different interface of index of refraction from light directing site area.
Referring now to Fig. 1, operation principle of the present utility model is briefly described.The light of LED light source 2 passes through incidence surface
101 are changed into pure white light into red and green color quantum dot region 104, enter back into light directing site area 105, incide reflecting surface 102
Exiting surface 103 is gone up and reached, diffusing reflection occurs and uniform light intensity at the site 106 of exiting surface 103, carried on the back with to liquid crystal display
Optical illumination.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
On the utility model can be made a variety of changes, be protection domain of the present utility model.
