Description
Technical field
The present invention relates to light guide plate field, more particularly to a kind of method for solving light guide plate and scratching.
Background technology
Liquid crystal display (LCD) is in dominant position in current FPD, and it has low-power consumption, light weight etc. prominent
Go out advantage, because itself can not light, modulation ambient light can only be relied on to reach display purpose.Backlight is to be located at liquid crystal
Show a kind of light source of device behind, its illumination effect will directly influence the visual effect of LCD MODULE.Side-light backlight
It is one of backlight of current backlight best results, and light guide plate is then component important in side-light type back light.
Appearance scuffing is bad during processing light guide plate at present can only scrap processing.
The content of the invention
The present invention proposes a kind of method for solving light guide plate and scratching, and solving can not lead to occur scratching in the prior art
The problem of tabula rasa is recovered.
The technical proposal of the invention is realized in this way：A kind of method for solving light guide plate and scratching, comprises the following steps：
(1) seamless mark is done to the abraded area on light guide plate；
(2) air-heater heating-up temperature is adjusted to 100~120 DEG C, wind speed is 3.4~5.4m/s, the hot blast pipette tips of air-heater
Toasted at the seamless mark of light guide plate；
(3) for abraded area by thermal softening, abraded area gradually recovers smooth, whether smooth observes abraded area again.
Preferably, in step (2) the hot blast pipette tips of air-heater apart from light guide plate 1mm~2mm.
Preferably, the light guide plate is the optical sheet that PMMA or PS materials are made.
Preferably, seamless be identified as is identified with soft pen core in light guide plate surface.
The beneficial effects of the invention are as follows：
The production yield of light guide plate can be lifted, reduces production cost；Reduce the wasting of resources；It is easy to operate, easily carry out.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the operation chart of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
PMMA is polymethyl methacrylate in the present invention, and PS is polystyrene plastics.
A kind of method for solving light guide plate and scratching, comprises the following steps：
(1) seamless mark 2 is done to the abraded area 5 on light guide plate 1；
(2) heating-up temperature of air-heater 3 is adjusted to 100~120 DEG C, wind speed is 3.4~5.4m/s, the heat gun of air-heater 3
First 4 are toasted at the seamless mark 2 of light guide plate 1；
(3) for abraded area 5 by thermal softening, abraded area 5 gradually recovers smooth, whether smooth observes abraded area 5 again.
As shown in figure 1, doing seamless mark 2 to the abraded area 5 of light guide plate 1, mainly act on hot blast pipette tips 4 during baking
The position, other positions are avoided by thermal softening.Because the material softening point of light guide plate 1 is typically between 100~120 DEG C, therefore
In this temperature range, it can soften light guide plate 1,3.4~5.4m/s of wind speed, the surface of light guide plate 1 be impacted, makes scuffing portion
It is rapid smooth after the softening of position 5.
In order to lift the bating effect of abraded area 5, in step (2) the hot blast pipette tips 4 of air-heater 3 apart from light guide plate 1 away from
From for 1mm~2mm.
Further, the light guide plate 1 is the optical sheet that PMMA or PS materials are made.PMMA sheet materials softening point is 113 DEG C,
PS sheet materials softening point is 103 DEG C.
Further, the seamless mark 2 is to be identified with soft pen core on the surface of light guide plate 1.Without using hard pen
Core, avoid again the surface of light guide plate 1 being caused to scratch.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
