Abstract
The utility model provides a kind of light guide plate, and it includes incidence surface, exiting surface and the bottom surface relative with the exiting surface, and the exiting surface is coated with granule proliferation, and the bottom surface is provided with lattice point structure.Light guide plate of the present utility model is integrated with the function of diffusion sheet, can improve outgoing light homogeneity.The utility model also provides a kind of backlight module using above-mentioned light guide plate.
Description
Technical field
The utility model belongs to display field, more particularly to a kind of light guide plate and the backlight module using the light guide plate.
Background technology
Because liquid crystal display has the advantages that light, thin, power consumption is small, be widely used in notebook, mobile phone,
Personal digital assistant etc. modernizes information equipment.Need to be it because the liquid crystal in liquid crystal display does not have the characteristics of luminescence in itself
Backlight module is provided to realize display function.Backlight module need to have higher emitting brightness, so as to lift liquid crystal display
The visible angle of color contrast, full frame regional luminance effect and complete machine.In addition, to adapt to light, the thin requirement of liquid crystal display,
Its structure design is unable to too complex.
The backlight module generally use light guide plate of prior art adds four layers of blooming piece：It is lower diffusion+under add lustre to+in add lustre to+
On add lustre to, cause complicated, assembling procedure is more, and cost is high.
Utility model content
The purpose of this utility model is the provision of a kind of light guide plate for being integrated with diffusion sheet function.
The utility model additionally provides a kind of backlight module using above-mentioned light guide plate.
In the utility model embodiment, there is provided a kind of light guide plate, it include incidence surface, exiting surface and with the exiting surface
Relative bottom surface, the exiting surface are coated with granule proliferation, and the bottom surface is provided with lattice point structure.
In the utility model embodiment, the granule proliferation uses UV particles.
In the utility model embodiment, the lattice point structure is molded by the way of impressing.
In the utility model embodiment, a kind of backlight module is also provided, it includes a light source, a light guide plate, a reflection
Plate and a brightening piece, wherein, the light guide plate has incidence surface, exiting surface and the bottom surface relative with the exiting surface, the light
The relatively described incidence surface in source is set, and the exiting surface is coated with granule proliferation, and the bottom surface is provided with lattice point structure.
Compared with prior art, light guide plate of the present utility model on bottom surface by imprinting lattice point structure, site knot
Structure can be distributed uniform light, the coating UV granule proliferation on exiting surface, will make exiting surface the light in conduction is broken up
Light out is more uniformly distributed, and plays a part of diffusion sheet, so that above-mentioned light guide plate is applied to backlight mould
During group, it can not have to that same effect can be played using diffusion sheet, so as to reduce the cost of backlight module.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Realization of the present utility model is described in detail below in conjunction with specific embodiment,
It is the stereogram for the backlight module that the utility model embodiment provides refering to Fig. 1.It is anti-that the backlight module includes one
Penetrate plate 11, a light guide plate 12, a brightening piece 13, a light source 14 and light source cover 15.The reflecting plate 11, light guide plate 12, brightening piece
13 are cascading.The light source 14 is set relative to the light guide plate 12, and is arranged in the light source cover 15.
Referring to Fig. 2, it is the structural representation for the light guide plate that the utility model embodiment provides.The light guide plate 12 includes
Incidence surface 121, bottom surface 122 and the exiting surface 123 relative with the bottom surface 122.The light source 14 is relative with the incidence surface 121
Set.The exiting surface 123 is coated with granule proliferation 1231, the light that exiting surface comes out more is uniformly distributed, plays diffusion
The effect of piece.The granule proliferation 1231 can use UV particles.
Referring to Fig. 3, it is the structural representation of the bottom surface for the light guide plate that the utility model embodiment provides.The bottom surface
122 are distributed with the lattice point structure of imprinting moulding, and lattice point structure can be distributed uniform light the light in conduction is broken up.
Fig. 4 is such as referred to, is the schematic diagram of the Making programme for the light guide plate that the utility model embodiment provides.Steel is made in advance
Board mold, lattice point structure is made on steel plate mould；Again guide-lighting boards half-finished product is placed between steel plate mould and roller
Row heat rolling, while UV granule proliferations are coated between roller and guide-lighting boards half-finished product, granule proliferation is attached to light guide plate
Exiting surface, guide-lighting board finished product is carried out after the completion of rolling and carries out covering protection film.
Compared with prior art, light guide plate of the present utility model on bottom surface by imprinting lattice point structure, site knot
Structure can be distributed uniform light, the coating UV granule proliferation on exiting surface, will make exiting surface the light in conduction is broken up
Light out is more uniformly distributed, and plays a part of diffusion sheet, so that above-mentioned light guide plate is applied to backlight mould
During group, it can not have to that same effect can be played using diffusion sheet, so as to reduce the cost of backlight module.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
