Description
Technical field
This utility model relates to technical field of LED display, particularly relates to a kind of novel backlight module.
Background technology
LASER Light Source module is the core of laser display technology, and the performance of light source module directly determines laser display
The quality of system.At present, laser display light source module faces two hang-ups: the volume of (1) light source module is big, light energy collection efficiency
The highest.(2) due to the coherence of LASER Light Source so that speckle occurs in the picture projected on coarse screen.
At present, in backlight assembly, light guide plate is crucial optical element, the light guiding points differed by various densitys,
Making light guide plate uniformly light-emitting, reflecting surface can be used for improving the service efficiency of light by the luminous reflectance of bottom surface to light guide plate.So
And, due to the diversity of LED light source so that luminous utilization rate is not high enough, for the light guide plate of large-size, can lead
The brightness causing light guide plate is low and uneven.Therefore, in order to improve optical property and the using effect of light guide plate, need to lead
Tabula rasa and diffusion barrier are applied in combination.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency present in prior art, and provides a kind of Novel back optical mode
Group, has integration degree high, easy to use, light guide plate is served protective effect simultaneously.
The technical scheme in the invention for solving the above technical problem is:
A kind of backlight module, including light guide plate substrate, LED light source, it is characterised in that: described light guide plate substrate have into
Bright finish, exiting surface, reflecting surface, described incidence surface is vertical with exiting surface, and described LED light source is arranged on described incidence surface
Side, described light guide plate substrate be shaped as right-angled trapezium, the inner side of described reflecting surface is printed with multiple light guiding points, described
Light guiding points be triangle, the outside of described reflecting surface is provided with layer of transparent film, and described exiting surface is provided with one layer of expansion
Dissipate film, be provided with multiple micro structure outside described diffusion barrier, be packaged with multiple quantum dot in described micro structure and uniformly divide
The light of the exiting surface described in cloth.
Preferably, the material of described light guide plate substrate is that Asia is made every effort to overcome or makrolon material.
Preferably, the structure of described diffusion barrier is semicircular arc.
Preferably, the outside of described hyaline membrane is provided with one layer of reflectance coating.
Preferably, described LED light source uses multiple LED lamp bar.
This utility model compared with prior art, has the following advantages and effect: light guide plate user of the present utility model
Just, excellent optical performance, and light guide plate is served protective effect.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, before not paying creative work
Put, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of novel backlight module in this utility model.
In figure, 1 is light guide plate substrate, and 2 is incidence surface, and 3 is exiting surface, and 4 is reflecting surface, and 5 is light guiding points, and 6 is hyaline membrane,
7 is reflectance coating, and 8 is diffusion barrier, and 9 is micro structure, and 10 is LED light source.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following example are right
Explanation of the present utility model and this utility model is not limited to following example.
Fig. 1 is the structural representation of a kind of novel backlight module in this utility model, and seeing Fig. 1 is a kind of backlight module,
Including light guide plate substrate, LED light source, described light guide plate substrate has incidence surface, exiting surface, reflecting surface, described incidence surface
Vertical with exiting surface, described LED light source is arranged on the side of described incidence surface, and being shaped as of described light guide plate substrate is straight
Angle is trapezoidal, and the inner side of described reflecting surface is printed with multiple light guiding points, and described light guiding points is triangle, described reflecting surface
Outside is provided with layer of transparent film, and described exiting surface is provided with one layer of diffusion barrier, is provided with multiple outside described diffusion barrier
Micro structure, is packaged with multiple quantum dot and is uniformly distributed the light of described exiting surface in described micro structure.
The material of described light guide plate substrate is that Asia is made every effort to overcome or makrolon material.The structure of described diffusion barrier is half
Circular arc.The outside of described hyaline membrane is provided with one layer of reflectance coating.Described LED light source uses multiple LED lamp bar.
The size of micro structure of the present utility model is little, and in it, kind and the ratio of the quantum dot of encapsulation are easily modulated and control
System, therefore, drastically increases the outgoing light homogeneity of light guide plate so that light guide plate has more preferable display quality.
Described light guide plate substrate is right-angled trapezium, and wherein, reflecting surface changes the total reflection light in light guide plate substrate
Angle, decrease the angle of bottom reflection light, on the one hand decreasing light reflexes to the angle of incidence of light guide plate substrate surface, makes
Must reflect light and be more nearly direction, on the other hand making originally can not be from light guide plate substrate because the angle of reflection light is excessive
This some light that surface refraction is gone out can reflect away in light guide plate surface, improves utilization rate and the brightness of light.
Above content described in this specification is only to this utility model example explanation.This utility model
Described specific embodiment can be made various amendment or supplements or use class by person of ordinary skill in the field
As mode substitute, without departing from the content of this utility model description or surmount model defined in the claims
Enclose, protection domain of the present utility model all should be belonged to.
