Background technology
Since the liquid crystal itself in panel of LCD does not have the characteristics of luminescence, thus, to reach display effect, must give Panel of LCD provides a planar light source device, such as backlight module, and function is to supply brightness to panel of LCD Area source that is abundant and being evenly distributed.
Prior art backlight module is made of light source, reflecting plate, light guide plate, diffuser plate and layers of prisms etc., wherein light guide plate It is the key component in backlight module, area source is converted into its role is to guide incident light to be scattered through light guide plate and reflect.
Existing light guide plate includes an incidence surface, a light-emitting surface adjacent with the incidence surface and one opposite with the light-emitting surface Bottom surface.The light source is arranged adjacent to the incidence surface, which is arranged adjacent to the bottom surface, which sets adjacent to the light-emitting surface It sets.Equally distributed multiple circular propagation points are provided on the bottom surface.The diffusion point, which effectively can be reflected and be spread, to be incident upon thereon Light, to improve the light utilization efficiency and outgoing light homogeneity of the light guide plate and the backlight module.
But the light that the light source is sent out, from after incidence surface enters light guide plate, some light need to pass through among light guide plate, Light path is longer, and need to pass through multiple reflections, can cause light loss, and luminous energy loss is larger, is utilized so as to cause the light of the light guide plate Rate reduces.
Utility model content
In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of novel lead Tabula rasa has the characteristics that simple in structure, esy to use, safe and reliable.
To achieve the above object, the utility model is using following technical solution:
A kind of light guide plate includes light conducting plate body, which has imports light conducting plate body by light beam Interior incidence surface, by light beam out of light conducting plate body derived light-emitting surface and the bottom surface opposite with light-emitting surface;Light conducting plate body Include quantum layer, PS layers and PC layers, the PS layers of upper surface for being covered in quantum layer;The PC layers of following table for being covered in quantum layer Face.
As a preferred embodiment, the light-emitting surface is located on PS layers.
As a preferred embodiment, the bottom surface is located on PC layers.
As a preferred embodiment, the multiple first guide-lighting slots are provided on incidence surface, the multiple first guide-lighting slots are continuously adjoining Arrangement.
As a preferred embodiment, the multiple second guide-lighting slots and uneven distribution are provided on bottom surface in the multiple of the bottom surface Scattering particles, the multiple second guide-lighting slot continuously adjoining arrangements.
As a preferred embodiment, the described first guide-lighting slot and the second guide-lighting slot are V-groove, U-type groove, dovetail groove or circular arc Shape slot.
As a preferred embodiment, the scattering particles is that the spherical shape made of two kinds of refractive index different material is hollow Structure.
The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology Known to scheme:
It is made of quantum layer, PS layers and PC layers light conducting plate body, the PS layers of upper surface for being covered in quantum layer;It should The PC layers of lower surface for being covered in quantum layer, quantum material absorbability is very big, can greatly improve sensitivity, and energy saving;This Utility model emergent ray narrows, improves light extraction briliancy, coordinates the scattering particles on bottom surface, makes light guide plate light extraction evenly.
More clearly to illustrate the structure feature and effect of the utility model, come below in conjunction with the accompanying drawings with specific embodiment pair The utility model is described in detail.
