Abstract
The present invention relates to a method for making microlens type light guide plate. It is mainly characterized by that on a plastic or wax mould base plate is adopts mechanical treatment method or non-traditional treatment method to make a pattern, said pattern can be concave or convex type, then utilizes baking thermal flow method to plasticize the plastic pattern into microlens pattern, and uses it as mother mould for electroforming reproduction, finally, adopts the electrotyping and jet-forming process to obtain the invented microlens type light guide plate.
Description
Technical field
The invention relates to a kind of manufacture method of microlens type light guide plate.
Background technology
Existing microlens type light guide plate production method is to invent the patent case No. 110552 as Taiwan, it mainly is to use the photograph resist of viscosity in 200 to 1200 centipoise scopes on the smooth base material to be included in, form the step of the photograph resist layer of thickness 5 to 30 μ m by spin coating, make photograph resist step of exposing, with the photograph resist that the exposed step of video picture in addition, make the table of photograph resist and the step of conduction, and electroforming step, make the surface and have the disconnected and stamping die of shape of micro concavo-convex, made stamping die is peeled off by the photograph resist, and made light conductor with its model as shaping usefulness.
In addition as No. 5776636 patent case of the U.S., mainly be to utilize the gold-tinted processing procedure to make lenticule picture on surface (microlens pattern), turn over film and injection molding is produced microlens type light guide plate through electroforming again.
No. 6002464 patent case of the U.S. also provides a kind of gold-tinted processing procedure, and its diffuser plate is mainly formed with lenticule, to reach the uniform purpose of light.
Above-mentioned existing microlens type light guide plate production method all is to utilize the gold-tinted processing procedure to make lenticule picture on surface (microlens pattern) to turn over mould and jetting process via electroforming at last, makes the moulding microlens type light guide plate.
Because gold-tinted process apparatus costliness, fabrication steps is many, and the processing procedure control ability must be strong, so its product fraction defective is higher, and its cost of manufacture is also higher relatively simultaneously.
The shortcoming of prior art also has in addition in its microlens type light guide plate processing procedure, because of direct processing metal die, causes quickening the abrasion of cutter; And small stipple pattern utilizes processing mode to be difficult for reaching mirror effect, and then influences its optical characteristics etc.
Every shortcoming that this case inventor derives in view of above-mentioned located by prior art is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully this part microlens type light guide plate production method is finished in research and development finally.
Summary of the invention
Purpose of the present invention promptly is to provide a kind of microlens type light guide plate production method, and it will process not readily accessible mirror and effect in the prior art, utilizes the baking heat flow method with the site micromirrorization, so that final products obtain good optical characteristics.
Of the present invention time a purpose is to be to provide a kind of microlens type light guide plate production method, and its use equipment is simple, and fabrication steps is less and be easy to control, makes its cost of manufacture cheap compared to existing gold-tinted processing procedure.
Another object of the present invention is to be to provide a kind of microlens type light guide plate production method, in its processing procedure on the one flat substrate making of moulding site more easy.
Can reach the microlens type light guide plate production method of foregoing invention purpose; mainly be with machining, Laser Processing or other processing mode on plastics or wax-pattern substrate; machine-shaping one pattern (pattern); this pattern can be matrix or convex pattern; and then utilize the baking heat flow method that this pattern is plastified into microlens type pattern (microlens pattern); and utilize electroforming to turn over modeling method; on the metal pattern of the pattern transfer on the substrate; with ejection formation or thermoforming way, produce a microlens type light guide plate at last.
Wherein this flat substrate is made with a wax-type material.
Wherein this flat substrate is made with a plastic material.
Description of drawings
See also the detailed description and the accompanying drawing thereof of following relevant a preferred embodiment of the present invention, can further understand technology contents of the present invention and purpose effect thereof; The accompanying drawing of relevant this embodiment is:
Figure 1A to Fig. 1 E respectively makes the member synoptic diagram of flow process for microlens type light guide plate production method of the present invention.
Embodiment
