War, improves cross cutting processing, the requirement of injection mo(u)lding simultaneously the most accordingly, and the crucial portion that backlight module is panel of LCD
One of part, by coordinating light emitting diode, the uneven point source sent be converted into one uniformly, stable and have one
Determine the planar light source of brightness, i.e. so-called backlight.
In prior art, light guide plate overlays in reflection blade without fixing, light after entering to inject light guide plate from incidence surface,
It is totally reflected inside light guide plate, until its total reflection is destroyed in the site encountering bottom surface, penetrates from the inside of light guide plate, the most instead
Penetrate the sheet lower section in the bottom surface of light guide plate, the luminous reflectance that non-exit facet transmits is returned, promote backlight efficiency.But,
In prior art, reflector plate separates with light guide plate, and general reflector plate ratio is relatively thin, needs backboard as support.The flatness of backboard has
Time can affect the quality of picture, about mechanical vibration it is demonstrated experimentally that separate type reflector plate and light conducting plate structure, the most mutually rub
Wound, also can affect picture quality.Develop towards the direction of ultra-thin narrow-frame now with smart mobile phone liquid crystal display module, narrow
Frame design makes existing shading pressure sensitive adhesive tape paste the limited area of diaphragm, and assembling para-position difficulty is big, and required precision is high, leads
Cause diaphragm easily to shift, thus exposure problem occurs.Additionally, due to existing shading rubber belt with the stickup of glue frame apart from limited, can
The phenomenon that shading rubber belt floats from glue frame can be there will be, thus cause product bad.
Utility model content
The purpose of this utility model is to provide a kind of reflection light plate integral structure, and it is by silk screen on light guide plate

The reflector plate that master batch is made.
Preferably, in the described light guide plate being used in backlight module, the plastics that described reflector plate uses are PP,
One in PET or PC.
Preferably, in the described light guide plate being used in backlight module, described light conducting plate body is thickness 1 ~ 5mm
Ultrawhite light chemically-strengthened glass or by PMMA plastics, PC plastics, MS plastics or the plastics of PS plastic extrusion calendering formation
Plate.
Preferably, in the described light guide plate being used in backlight module, the guide-lighting site warp of described light conducting plate body
Cross screen painting.
The beneficial effects of the utility model are, reflector plate is attached on described light guide plate by this utility model, is substantially reduced
Friction between light guide plate and reflector plate, and make reflector plate not rely on back plate support, affected light by backboard flatness
Problem according to quality is substantially reduced, easy to use, and process black shading glue is the most simple to operate, and effectively blocks refraction
The light leak of light, makes backlight be fully used；Light guide plate consistency improvement after Fu He；Simultaneously in links such as shipping storage
Light guide plate can be played a good protection.This utility model, by integrated to reflector plate, light guide plate, brings convenience for using；
The most also Simplified flowsheet, reduces cost.
Accompanying drawing explanation
Fig. 1 is existing back light source structure schematic diagram；
Fig. 2 is this utility model full view；
Fig. 3 is this utility model partial sectional view.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As it is shown in figure 1, the backlight of prior art includes metal framework 1, glue frame 2, light guide plate 3, reflector plate 4, blooming
Sheet group 5, light guide plate and reflector plate are two indispensable major optical parts.In prior art, light guide plate stacks without fixing
In reflection blade, light, after entering to inject light guide plate from incidence surface, is totally reflected inside light guide plate, until encountering bottom surface
Its total reflection is destroyed in site, penetrates from the inside of light guide plate, and wherein reflector plate is in the lower section of the bottom surface of light guide plate, by non-exit facet
The luminous reflectance transmitted is returned, and promotes backlight efficiency.But, in prior art, reflector plate separates with light guide plate, the most anti-
Penetrate sheet ratio relatively thin, need backboard as support.The flatness of backboard affects the quality of picture, relevant mechanical vibration experiment card sometimes
Bright, separate type reflector plate and light conducting plate structure, wound of the most mutually rubbing, also can affect picture quality.As shown in Figures 2 and 3, this reality
With a kind of light guide plate being used in backlight module of novel offer, including: light conducting plate body 7, it is provided with guide-lighting site 6, leads
Tabula rasa body 7 is the ultrawhite light chemically-strengthened glass of thickness 1 ~ 5mm or is moulded by PMMA plastics, PC plastics, MS plastics or PS
The plastic plate of material extrusion calendaring molding.Light conducting plate body is through screen painting；Reflector plate 9, it is by the black pressure of silk screen printing
Quick glue 8 is pasted onto in described light conducting plate body 7, and reflector plate is the reflector plate using plastics and reflection master batch to make, and reflector plate leads to
The mode crossing rolling is pasted in light conducting plate body, and the plastics that reflector plate uses are the one in PP, PET or PC.
This utility model uses screen printing technique off-set oil by checking on qualified glass plate or plastic plate any surface
Ink forms guide-lighting site 6, and printing carries out gray scale test to glass plate behind guide-lighting site, it is ensured that the light of the guide-lighting catadioptric injection in site
Even intensity.Black pressure-sensitive adhesive 8, by silk-screen printing technique, is printed in light conducting plate body 7.Described colloid curing mode is heat
Solidification or photocuring, the THICKNESS CONTROL after its solidification is consistent with guide-lighting dot surface 6.Described reflector plate 9 is led described in being attached at
It is on tabula rasa 7 dot surface by the way of rolling, between described light guide plate 7 and reflector plate 9, leaves the thinnest gap, anti-to ensure
Penetrate sheet 9 to be unlikely to be close to light guide plate 7, affect light total reflection in light guide plate 7, the gap between light guide plate 7 and reflector plate 9
For 0-0.2 millimeter.
Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment
Listed utilization.It can be applied to various applicable field of the present utility model completely.For those skilled in the art,
It is easily achieved other amendment.Therefore under the general concept limited without departing substantially from claim and equivalency range, this reality
