Preferably, the micro-structure site is the ring-shaped structure imprinted along the substrate bottom surface.
Preferably, the boss is right-angled trapezium, and the right angle waist of the right-angled trapezium is vertical with the light path of incident light source.
Preferably, the substrate uses acrylic material or makrolon material.
Also a kind of preparation method of slimming light guide plate of the present invention, includes the following steps：
1）Raw material produces plank by extrusion equipment；
2）The polished roller of plank is cut after being polished, and becomes the big plate of requirement up to specification；
3）Substratum transparent with right-angled trapezium boss is impressed into the coated face of big plate by embossed mold；
4）Illumination curing is carried out to the glue-line on big plate, then carries out precision die cutting, becomes and meets dimensions requirement
Platelet；
5）The transfer of micro-structure site is carried out to the uncoated face of platelet through hot pressing printing apparatus；
6）Protective film is covered to the two sides of platelet using laminating machine, slimming light guide plate completes.
Further, step 3）In, the substratum transparent is coated equipment has inversion right-angled trapezium notch to one end
Imprint mold carry out UV glue application formation.
Preferably, step 5）In, the hot pressing printing apparatus includes the light guide wheel of upper end and the coining wheel of lower end, the coining wheel
On be provided with it is multiple for transferring out the protrusions of micro-structure site.
Further, step 5）With step 6）Between further include having electrostatic step, the painting using ion fan to platelet
Cloth cover carries out electrostatic.
By above technical scheme it is found that the substratum transparent incidence end of guide-lighting plate top surface is designed to boss by the present invention, this is convex
The apical side height of platform is adapted with the upper end light path of incident light source, while realizing slimming, with LED light thickness matching, is reached
To the requirement of brightness.
