Description
Technical field
The present invention relates to light guide plate manufacture field, a kind of more particularly to lifting has bell-mouthed light guide plate
The speed of response and quality, and effectively reduce the manufacture method and its equipment of the bell-mouthed light guide plate of tool.
Background technology
Now, backlight module has been widely used, especially the display surface to be arranged in various electronic installations
Hardened structure is large.General display panel structure is combined by a panel one backlight module of collocation.Meanwhile,
With the use habit and the market demand of the common people now, display panel is also directed to lightening direction to be developed, and
The thickness and weight for reducing backlight module are one of reduction display panel overall structure mode.Traditional backlight
Module is constituted, to provide panel at least by light source such as LED with the primary clustering such as light guide plate or light leading diaphragm
Light shows pattern or word, and can set up such as reflecting plate component according to remaining consideration, lifts backlight mould
The light of block is presented effect.Therefore, the integral thickness and weight of backlight module to be reduced, can lead for this
The thickness of tabula rasa or light leading diaphragm is improved and is designed.
In theory, when the thickness of light guide plate or light leading diaphragm declines, its incidence surface size can be caused to be less than light
Source size, the light for sending light source cannot be exposed in light guide plate or light leading diaphragm completely, cause light
Amount is not enough, thus it is existing it is plate with wedge type light guide plate or light-leading film cannot in the case where lightening requirement is met,
Meet the enough amount lights of incidence surface fechtable simultaneously.Therefore the coping style for using at present is in light guide plate
Or the incident side of light leading diaphragm follows dimension of light source to set up a taper structure (taper), industry is also referred to as loudspeaker
Mouth, so that the light of light source can borrow the taper structure to enter in the light guide plate or light-leading film, lifts light
The utilization rate of line.Similarly, tool taper structure light guide sheet or light-leading film in order to meet optical design with
Improving optical guide effect, also as light guide plate or light-leading film, can have disposed thereon the micro- knot of optics as
Composition sample, to strengthen optical effect.
At present, also there are various modes for making tool taper structure light guide plate or light-leading film.One is utilization
Injection molding method is made, and can directly form optical microstructures by its die simultaneously in ejection formation.
But the light guide plate or light-leading film of the tool taper structure that current plastic ejection moulding is made, its minimum thickness is only
0.4~0.5mm can be reached, if light guide plate or guide-lighting thin mould thickness need to be further reduced, or using height
The injection type of firing rate, only this measure will face surface and the structure flatness defect of light guide plate or light-leading film.
Therefore the mode of current ejection formation still cannot effectively reduce the thickness of light guide plate or light-leading film, thus not
Symbol is current to light guide plate or the thickness requirements of light-leading film.
Secondly be the base material by the light guide plate of web-like or light-leading film, using design reeded pair of rollers its
Carry out spreading, it is formed projection in one side via spreading, and needed for taper structure shape by
One is sequentially cut.This kind of mode is also known as outside line processes, and it must in addition design rolling for taper structure
Secondary operation is taken turns and carried out, and taper structure cannot be directly formed after spreading, and need cleaved processing procedure again
So that final light guide plate or shape needed for light-leading film product formation, though can have compared to injection molding method
Effect reduces finished product thickness, but pole expends processing time and causes the slow situation of the speed of response.
Thirdly being the transfer apparatus and light leading diaphragm as described in Taiwan Patent application TW201444664A
Manufacture method, it uses the substrate by the light guide plate of web-like or light-leading film, using with wedge hollow
A mould combination glue-line suppress to form taper structure.The substrate has a relative exiting surface and a bottom surface,
And in the glue-line of bottom-surface coated one first, imprinted and consolidated for first glue-line using a transfer roller
Change and the bottom surface by first glue-line formed optical microstructures, then, one first in the mould is recessed
Groove inserts a transfer mold, and the mould has one second groove simultaneously, is coated one second glue-line in this turn
In die and second groove, the exiting surface of the Bigpian is pressure bonded to second glue by a pressing roller
Layer simultaneously solidify, make second glue-line combine the exiting surface and formed to should the second groove taper structure
And to should transfer mold optical microstructures, finally cut the substrate and produce the light leading diaphragm.This
The mode of kind must also pass through first glue-line and the setting of second glue-line in addition to it need to correspond to and design the mould
Taper structure and optical microstructures just can be over the substrate formed, it is relative with material cost complicated in processing procedure
With costliness.Or compared to above two mode, seem taper structure only need according to the mould this is second recessed
Groove is formable, and need not carry out cutting action for taper structure again, but actually in response to different size
Or the taper structure of shape then needs to make corresponding mould one by one, the production cost shared by mould is also with big
Width is lifted.Further, since taper structure and optical microstructures are all first glue-line and second glue-line is attached
And formed on the substrate, therefore the not original substrate of light leading diaphragm integral thickness of final finished
Thickness, and influenceed by first glue-line and second glue-line and be substantially improved, it is not inconsistent lightening now wanting
Ask.
Its four be by light guide plate or light-leading film, it is separately manufactured with taper structure, then through UV glue by two
Person binds, to form the light guide plate or light-leading film of tool taper structure.This kind of mode is due to saturating by two structures
Cross bonding Joint, therefore the important document such as material and thickness regarding light guide plate or light-leading film and taper structure,
Required UV glue physical property and the property changed also can drops, it is therefore necessary to all kinds of light guide plates for production or
Light-leading film carries out impregnation action, even and this mode also needs secondary repeatedly processing, thus system is substantially improved
Numerous and diverse degree and the time of consuming in journey.In addition, close wedge type must be ensured in processing is binded through UV gluings
Relative position of the structure on light guide plate or light-leading film, it is to avoid the light guide effect of influence output finished product, and
Also the situation of displacement is come off from light guide plate or light-leading film or produced there may be taper structure, causes output
The situation that yield declines.
