Abstract
The utility model provides a slimming light guide plate, including the base plate, the substratum transparent has been laid to the top surface of this base plate, and the bottom surface hot pressing of this base plate is printed on the micro -structure site of total reflection, the incident end of substratum transparent is formed with boss, the top surface height of this boss and the upper end light path looks adaptation of incident light source. The utility model discloses design into the boss with the substratum transparent incident end of light guide plate top surface, the top surface height of this boss and the upper end light path looks adaptation of incident light source when realizing the slimming, mate with LED lamp thickness, reach the requirement of luminance.
Description
Technical field
The utility model relates to LCD backlight source technical field, is specifically related to a kind of slimming LGP.
Background technology
For side entrance back module, comprise the assemblies such as light source, LGP, all kinds of bloomings. LGP is the most key part wherein, and its Main Function is guiding scattering of light direction, the spot light of side incident is converted into the uniform area light source of positive outgoing, improves brightness and the uniformity of backlight module. Along with the development trend of flat panel display equipment slimming, for small size, (3 ~ 10 ") backlight is also more and more thinner, and key component LGP and LED lamp also will be toward slimming development. Light guide plate also requirement can reach 0.2 ~ 0.6mm, and the thickness that LED lamp generally uses for 0.4mm and more than, be not enough to meet the demand for development of slimming.
Utility model content
The utility model provides a kind of slimming LGP, is applied on small size backlight module, realizes the slimming of backlight.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of slimming LGP, comprise substrate, the end face of this substrate is equipped with substratum transparent, and the bottom surface hot padding of this substrate is useful on brokenly the micro-structural site of ring light path total reflection, the incident end of described substratum transparent is formed with boss, and the upper end light path of the apical side height of this boss and incident light source is suitable.
Preferably, described micro-structural site is the circular ring along described substrate bottom surface impression.
Preferably, described boss is right-angled trapezium, and the right angle waist of this right-angled trapezium is vertical with the light path of incident light source.
Preferably, described substrate adopts acrylic material or Merlon material.
From above technical scheme, the substratum transparent incident end of LGP end face is designed to boss by the utility model, and the upper end light path of the apical side height of this boss and incident light source is suitable, in realizing slimming, with LED lamp thickness matching, reach the requirement of brightness.

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, described slimming LGP comprises substrate 10, and the present embodiment adopts acrylic board, thickness is 0.2 ~ 0.6mm, and the end face of described substrate is equipped with substratum transparent 20, is preferably UV glue-line, its thickness is 0.003 ~ 0.02mm, and hardness, up to 2H, plays good wear-resisting anti-scratch function. The bottom surface hot pressing of described substrate 10 is printed on micro-structural site 30, and this micro-structural site is preferably a kind of circular ring along described substrate bottom surface impression, for the total reflection of broken ring light path, plays the effect of scattering netted dot.
Small size (3 ~ 10 ") backlight slimming design; light guide plate will reach 0.2 ~ 0.6mm; need to mate LED light source 40(thickness and be 0.4mm and more than) use; can be formed with boss 21 at the incident end of substratum transparent 20, the upper end light path of the apical side height of this boss and LED light source 40 is suitable. Described boss 21 is designed to right-angled trapezium, the right angle waist of this right-angled trapezium is vertical with the light path of LED light source 40, and design can import incident light source in LGP completely like this, and can meet slimming demand, be applied on small size backlight module, realize the slimming of backlight.
The preparation method of the utility model slimming LGP, use that Ya Like sheet material (PMMA) is extruded, cut, UV glue laminated prints, be dried, be cut into platelet, site impresses, final molding, wherein UV glue laminated seal is that UV glue application is on impressing mould, impressing mould impresses with sheet material again, and UV glue is transferred on sheet material.
The preparation method of 2 pairs of slimming LGPs specifically describes as follows by reference to the accompanying drawings:
001:PMMA particle is produced acryl plates by extrusion equipment;
002: sheet material cuts after polishing running roller carries out polishing, become the large plate of requirement up to specification;
003: the coated face that through impressing mould, the substratum transparent with right-angled trapezium boss is impressed into large plate, this substratum transparent is that the impressing mould 52 that one end is had to inversion right-angled trapezium notch through coating apparatus 51 carries out the formation of UV glue application, with reference to Fig. 3, before impression, also need impressing mould 52 to overturn;
004: the glue-line on large plate is carried out to illumination curing, generally, by UV light irradiation, carry out dry solidification, make its hardness to more than 2H, there is anti scuffing function, then carry out precision die cutting, become and meet the platelet that dimensions requires;
005: through hot padding equipment, the non-coated face of platelet is carried out the transfer printing of micro-structural site, wherein hot padding equipment comprises the photoconduction wheel 61 of upper end and the impression wheel 62 of lower end, is provided with multiple projections that go out micro-structural site for transfer printing, with reference to Fig. 4 on this impression wheel;
006: use ion fan to remove static to the coated face of platelet;
007: then use laminating machine to cover diaphragm to the two sides of platelet;
008: slimming LGP finished product completes.
The above embodiment is only that preferred embodiment of the present utility model is described; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
