Description
Technical field
The utility model relates to backlight module field more particularly to a kind of Novel saw dentation light guide plates and backlight module.
Background technique
It is higher and higher to the quality requirements of mobile phone backlight module with the update of liquid crystal display industry, especially with
Light guide plate it is more and more thinner, light-conducting board mold machining accuracy and moulding process are promoted under limited situation, the production product of light guide plate
Matter is worse and worse, it is easy to the defects of light guide plate periphery forms flash, burr, burr.Do backlight module vibratory test and
During mobile phone complete machine fall-down test, burr burr of light-guide edge etc. can fall off, and form dust, and dust is moved to screen area
Domain and form black-white point, cause to show bad.Although now can be by throwing the technique on side, with diamond or tungsten carbide tipped tool to leading
Tabula rasa edge is polished, will because form it is bad caused by flash, burr, burr the defects of dispose, but light guide plate and LED
The incidence surface of contact could eliminate the lamp eye phenomenon of LED generation due to needing sawtooth well, however prior art can not be right
Light guide plate serrated face is processed by shot blasting.Therefore, how to eliminate the size flash generated in ultra-thin LGP forming process, burr, drape over one's shoulders
The defects of cutting edge of a knife or a sword, becomes one and contains problem to be solved.
As shown in Figure 1, the design of existing light guide plate sawtooth is generally used the design through entire incidence surface, i.e. incidence surface
Sawtooth extend to light-emitting surface from baseplane.As shown in Fig. 2, the baseplane 100 of light guide plate be normally at mold divide mould
Face, site mode and sawtooth mold insert 200 can be in close contact in forming process, thus this face does not have injection molding material from sawtooth 300
It is overflowed in gap, forms burr, burr etc..But in light-emitting surface 400, because sawtooth mold insert 200 has the height of 300 part of sawtooth super
The height of light guide plate incidence surface is gone out, injection molding material can overflow to form sawtooth burr burr from the gap of sawtooth mold insert 200
Etc. bad.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of Novel saw dentation light guide plate and backlight mould are provided
Group, solves the burr generated when injection molding sawtooth and burr etc. is bad.
The technical solution of the utility model is as follows: a kind of Novel saw dentation light guide plate, including light conducting plate body are provided, it is described
Light conducting plate body includes incidence surface, baseplane and light-emitting surface, and the incidence surface is equipped with several sawtooth, and the sawtooth lines up one
Row is distributed on incidence surface, and sawtooth lower end surface is concordant with light guide plate baseplane, and end face and light-emitting surface be at a distance thereon.
Further, the sawtooth upper surface and light-emitting surface distance are 0.03mm-0.05mm.
Further, the sawtooth upper surface and light-emitting surface distance are 0.03mm.
Further, the light-emitting surface is lozenges close to one end of incidence surface, and the other end is plane.
Further, spaced apart between adjacent two sawtooth.
Further, the sawtooth is triangle or arc-shaped.
Further, the baseplane is equipped with several sites.
Further, the root face of the sawtooth and incidence surface are located in same level, the tooth tip of sawtooth protrude from into
Smooth surface.
A kind of backlight module, including the Novel saw dentation light guide plate as described in any of the above item.
Using the above scheme, the sawtooth being located on light guide plate incidence surface is shortened a distance by the utility model, makes sawtooth
Upper surface separates out smooth surface 0.03-0.05mm, the channel that injection molding material can be blocked to overflow when processing in this way, can prevent sawtooth burr,
The generation of burr, simultaneously as this bit of just reduction 0.03-0.05mm of sawtooth, will not influence the spectrophotometric result of sawtooth.This reality
It is bad with the novel sawtooth burr for preventing light guide plate from generating during molding, burr etc., the quality of light guide plate is promoted, is changed
The effect of kind backlight module.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 3, the utility model provides a kind of Novel saw dentation light guide plate, including light conducting plate body, the leaded light
Plate ontology includes incidence surface 10, baseplane 20 and light-emitting surface 30, and the incidence surface 10 is equipped with several sawtooth 40, the sawtooth
40 are arranged in a row and are distributed on incidence surface 10, and 40 lower end surface of sawtooth is concordant with light guide plate baseplane 20, thereon end face 41 and light out
Face 30 is at a distance.The sawtooth upper surface 41 and 30 distance of light-emitting surface are 0.03mm-0.05mm, in this implementation
In example, the sawtooth upper surface 41 is 0.03mm with 30 distance of light-emitting surface.The lower end surface and bottom of conventional light guiding plate sawtooth
Plane is concordant, and upper surface is concordant with light-emitting surface, and a distance is shortened in the upper surface 41 of sawtooth 40 by the utility model, makes sawtooth
Upper surface 41 is apart from light-emitting surface 0.03mm or so.Correspondingly, as shown in figure 4, the sawtooth mold insert 50 for being used to process sawtooth is also contracted
Short 0.03mm or so, the channel for thus having blocked injection molding material to overflow, can prevent the generation of sawtooth burr, burr, simultaneously as
Sawtooth 40 just shortens 0.03mm, does not interfere with the spectrophotometric result of sawtooth 40.
The light-emitting surface 30 is lozenges close to one end of incidence surface 10, and the other end is plane.Certainly, light-emitting surface 30
Can a generally horizontal plane, this design for being usually used in small size light guide plate, technique is relatively easy.By light-emitting surface 30 close to enter light
The one end in face is set as lozenges, so that light guide plate changes linearly, is mainly used in the LCD of the larger sizes such as notebook
On, it is at low cost, light-weight, there is optics modulability.
The root face and incidence surface 10 of the sawtooth 40 are located in same level, and the tooth tip of sawtooth 40 protrudes from incidence surface
10.Spaced apart between adjacent two sawtooth 40, the sawtooth 40 can be triangle or arc-shaped, according to the reality of LED
Illumination effect is selected.It is scattered, is made by the light that setting sawtooth 40 can more effectively issue LED luminescence component
The emergent light for obtaining light guide plate is uniform, improves the utilization rate of LED luminance, energy saving, reduces cost.
The baseplane is equipped with several sites, and the light that incidence surface is injected is converted into face light by site diffusing reflection
Source.
The utility model additionally provides a kind of backlight module comprising Novel saw dentation described in above-described embodiment is guide-lighting
Plate, which can be applied in the electronic equipments such as mobile phone, plate.
In conclusion the sawtooth being located on light guide plate incidence surface is shortened a distance by the utility model, make sawtooth upper end
Face separates out smooth surface 0.03-0.05mm, and the channel that injection molding material can be blocked to overflow when processing in this way can prevent sawtooth burr, burr
Generation, simultaneously as sawtooth this it is a bit of just reduce 0.03-0.05mm, will not influence the spectrophotometric result of sawtooth.This is practical new
Sawtooth burr, burr that type can prevent light guide plate from generating during molding etc. are bad, promote the quality of light guide plate, improve back
The effect of optical mode group.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
