Description
Technical field
The present invention relates to the manufacture method of a kind of light guide plate, be specifically related to the manufacture method of a kind of composite light guide plate.
Background technology
Liquid crystal display itself is the most luminous, needs to configure backlight and just can realize the effect of display, traditional liquid crystal
Display screen includes a liquid crystal panel and a backlight module, is guided to liquid crystal panel by light by backlight module, makes
Liquid crystal panel is luminous, and light guide plate is exactly most important element in backlight module, goes out radiance in order to increase light guide plate
Degree, reduces light loss, it usually needs arrange reflection diaphragm, light guide plate and reflection in the side of light guide plate and bottom surface
Diaphragm is typically two independent elements, in the assembling process of backlight module, needs to arrange the most individually work
Sequence is fitted together, but due to light guide plate and the operation made in tolerance and assembling process of reflection diaphragm
Error makes to exist between light guide plate and reflection diaphragm gap, it is impossible to the leakage of bottom surface of light guide plate and side is completely eliminated
Optical phenomenon, causes luminous energy to be lost, and reduces and light briliancy.
Summary of the invention
It is an object of the invention to provide a kind of composite light guide plate light guide plate and reflectance coating being combined into one
Manufacture method, the method is simple to operate, with low cost, and gapless between the light guide plate of acquisition and reflective coating,
It is effectively reduced light loss.
The manufacture method of a kind of composite light guide plate of technical solution of the present invention, comprises the steps:
(1) providing a light guide plate, this light guide plate includes an incidence surface a, exiting surface, relative with exiting surface
Bottom surface and connect exiting surface and each side of bottom surface, described bottom surface and side are carried out micro Process, are allowed to
There is uniform roughness, described roughness Ra=0.05～0.07；
(2) light guide plate described in step (1) is cleaned, dries；
(3) in incidence surface and the protection of exiting surface overlay film of step (2) described light guide plate；
(4) preparing high reflecting medium solution, described high reflecting medium solution is by silver ammino solution and reducing solution
It is uniformly mixed；
(5) light guide plate described in step (3) is immersed in described high reflecting medium solution, described exiting surface with
Contain the container bottoms contact of solution；
(6) this light guide plate is taken out flushing, dries, and be coated with gelatin in silver-plated bottom surface and side, dry,
Tear protecting film.
Preferably, the manufacture method of a kind of composite light guide plate of the present invention, described step (2) is cleaned and is led
The method of tabula rasa is successively with suds cleaning, tap water and distilled water flushing, then molten at 10% stannum dichloride
Immersion bubble 5min, finally uses distilled water flushing.
Preferably, the manufacture method of a kind of composite light guide plate of the present invention, in described high reflecting medium solution
Dropping oil sodium hydroxide solution, the PH of described high reflecting medium solution is 9-10.
The technology of the present invention beneficial effect:
The reflectance coating of the composite light guide plate described in technical solution of the present invention is molten with reproducibility by high reflecting medium solution
After liquid effect, Direct precipitation is solidificated in the bottom surface of light guide plate and side forms, and protects described topcoating cloth gelatin
Protect, the reflective coating firm stable obtained, and with light guide plate intimate contact, be prevented effectively from light side leakage
Problem.
Detailed description of the invention
For ease of skilled artisan understands that technical solution of the present invention, in conjunction with specific embodiment to skill of the present invention
Art scheme is described further.
The manufacture method of a kind of composite light guide plate of technical solution of the present invention, comprises the steps:
(1) providing a light guide plate, this light guide plate includes an incidence surface a, exiting surface, relative with exiting surface
Bottom surface and connect exiting surface and each side of bottom surface, for making high reflecting medium solution make with reducing solution
Can be solidificated on described bottom surface and side by Direct precipitation with the silver obtained, bottom surface and side carried out micro Process,
Be allowed to that there is uniform roughness, its roughness and ordinary plate glass roughness quite, as its table can be made
Surface roughness is Ra=0.006；
(2) light guide plate described in step (1) is cleaned, dries；
(3) in incidence surface and the protection of exiting surface overlay film of step (2) described light guide plate；
(4) preparing high reflecting medium solution, described high reflecting medium solution is by silver ammino solution and reducing solution
Being uniformly mixed, as preferably, reducing solution here may select aldehyde radical solution or potassium sodium tartrate solution
Deng, further preferably, the present embodiment selects glucose solution；
(5) light guide plate described in step (3) is immersed in described high reflecting medium solution, described exiting surface with
Containing the container bottoms contact of solution, incidence surface, bottom surface and the side of overlay film protection contact with solution；
(6) this light guide plate is taken out flushing, dries, for protecting the silver coating on light guide plate, at the silver-plated end
Face and side are coated with gelatin, dry, protecting film of tearing.
It is successively with suds cleaning, tap water and distilled water punching that described step (2) cleans the method for light guide plate
Wash, then soak 5min at 10% stannous chloride solution, finally with distilled water flushing, use suds and from
After water cleans light guide plate, owing to tap water existing K+、Ca2+Plasma and be unfavorable for the generation of silver coating,
Therefore, also need to after washing from the beginning use distilled water flushing, and tin ash is as sensitizer so that silver coating is equal
Even.
Dripping sodium hydroxide solution in described high reflecting medium solution, the PH of described high reflecting medium solution is
9-10, drips sodium hydroxide solution in high reflecting medium solution and improves the PH of solution so that high reflecting medium
Reaction between solution and reducing solution can the most quickly be carried out.
Invention is exemplarily described by technical solution of the present invention above in conjunction with specific embodiment, it is clear that this
Bright implementing is not subject to the restrictions described above, as long as the method design that have employed the present invention is entered with technical scheme
The various unsubstantialities of row improve, or the most improved design by invention and technical scheme directly apply to other
Close, all within protection scope of the present invention.
