Detailed description of the invention
With embodiment, the embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.It is understood that this
Specific embodiment described by place is used only for explaining the embodiment of the present invention, rather than the restriction to the embodiment of the present invention.Additionally also
It should be noted that for the ease of describing, accompanying drawing illustrate only the part relevant to the embodiment of the present invention rather than entire infrastructure.
Show with reference to the flow process that Fig. 1, Fig. 1 are a kind of methods preparing ultrathin backlight die set that the embodiment of the present invention provides
It is intended to.
In FIG, the described method preparing ultrathin backlight die set includes:
Step 101, light guide plate, reflector plate and high-strength super thin aluminum sheet are dried, cleaning process；

Incident side be processed by shot blasting, its excess-three side of described light guide plate carries out printing light leakage by the high anti-ink mode of silk-screen；
After the site of described light guide plate uses the high anti-ink mode of described silk-screen to print, the Difference Control of described light guide plate is 20%, all
Evenness controls 75%.
Described reflector plate is web-like, and described reflector plate uses high transmissive optical glue application in advance, in single-sided back-adhesive form, and institute
The back-adhesive surface stating reflector plate is less than 1.35 with release paper protective layer, the refractive index of described high light-transparent glue, described reflector plate
Size is equivalently-sized with described light guide plate.
The thickness of described high-strength super thin aluminum sheet is 0.2mm to 0.4mm, the size of described high-strength super thin aluminum sheet and described leaded light
Plate equivalently-sized.
Concrete, light guide plate uses good rigidly, is little affected by the glass light guide plate of damp and hot change impact, and thickness 1-2mm is thick
Degree is conventional 3mm thickness plastic cement light guide plate less than in industry, can make the thinning 1-2mm of complete machine, have thinning advantage, and glass light guide plate enters light
Side throwing optical processing, its excess-three side replaces tradition patch reflection bar mode light leakage by the high anti-ink of silk-screen, effectively solves machinery and shakes
Reflection bar risk easy to fall off in dynamic experiment.
Light guide plate mesh point use IR ink silk screen printing mode, laser carving technique easily cause site burst apart, UV ink printing light guide plate
Brightness is on the low side, and after printing, light guide plate aberration requires to control within 20 ‰, and the uniformity controls more than 75%, and aberration is relatively big, all
Evenness is relatively low, complete machine can be caused to regard effect bad, needs, by adjusting polaroid and concentration piece mist degree reinforcement, to increase cost.
Web-like reflector plate uses high transmissive optical glue application in advance, and in single-sided back-adhesive form, back-adhesive surface is protected with release paper
Sheath, glue refractive index have to be lower than 1.35, if glue refractive index is higher than 1.35, close to glass light guide plate self refractive index
1.51, glue substitute air layer as dielectric breakdown the total reflection condition of light, then after reflectance coating is fitted with light guide plate, enter flash ranging
There will be bright band.The reflectance coating that application completes is cut by cross cutting, and size is consistent with light guide plate, it is simple to laminating para-position.
Super thin aluminum sheet thickness is 0.2-0.4mm, it is desirable to surface smoothness is good, can pass through according to different complete machine moulding demands
Overlay film or spraying coating process realize abundant outward appearance, and size is consistent with light guide plate.The rigidity of glass light guide plate is more than 20 times of plastic cement,
Super thin aluminum sheet can be by the thinning aluminium plate thickness of its high intensity after fitting with it.
Step 102, pastes described light guide plate with described high-strength super thin aluminum sheet with the laminating of described reflector plate, described reflector plate
Close, and be heating and curing after laminating.

Matter etc.), for causing bubble, dust because of dust, impurity, moisture etc. during avoiding follow-up laminating, affect backlight module entirety and put down
All brightness, uniformitys etc..Under the conditions of ambient temperature and moisture, utilize special for automatic abutted equipment first by light guide plate mesh point face and reflection
Sheet optical surface is fitted by OCA mode, then fits non-optical for reflector plate with the non-outer bright finish of aluminium sheet.Heating furnace arranges temperature in advance
Degree, keeps constant temperature, and temperature controls at 50-60 DEG C, after sample bonding process completes, is directly placed in heating furnace and carries out adding thermosetting
Changing, temperature retention time 3-5min, under the conditions of this temperature and time, glue is curable completely, and higher than this temperature range, transmitting film is variable
Shape.After being heating and curing, take out sample, carry out room temperature and cool down.All enter in ten thousand grades of toilets during whole laminating
OK.
Another kind of method is: by dot surface and the optical surface laminating of described reflector plate, the described reflector plate of described light guide plate
Non-optical and the non-outer bright finish laminating of described high-strength super thin aluminum sheet, and be heating and curing after laminating.By special from

With automated cleaning equipment, 1,2,3 three parts are carried out (dust, impurity etc.), dry, for avoiding follow-up laminating process
Middle cause bubble, dust because of dust, impurity, moisture etc., affect backlight module ensemble average brightness, the uniformity etc..Utilize special
First light guide plate mesh point face is fitted by automatization's abutted equipment with reflector plate optical surface, more non-with aluminium sheet by non-optical for reflector plate
Outer bright finish is fitted, and after attaching process completes, is heating and curing, and solidification temperature is less than material deformation temperature.
Laminating glued membrane 41,42 is a kind of Optical transparent adhesive, has superior definition, caking property, moisture-proof heat-resisting weather-proof
Property, and its light transmission is higher by 3% than optical cement OCA, especially has the anti-seismic performance of excellence, and efficiency of fitting is high, is substantially reduced
Traditional mode of production cost and loss.
