[0045] The following is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the liquid viscous raw material 300 is a transparent liquid viscous raw material 300, which is silicone structural adhesive, polyurethane adhesive or organic adhesive. One of silicon structural adhesives, corresponding to the reflective material powder 400 is a mixture of one or more of silicon dioxide, titanium dioxide, cornstarch, white PET fine powder or yellow fluorescent powder. Its proportioning and technical effects are the same as those of the second embodiment, and will not be repeated here.

[0046] The following is the fourth embodiment of the present invention. In this embodiment, the transparent liquid viscous raw material 300 is acrylic ink, epoxy resin ink, polyurethane ink, polyester ink, vinyl ink or rubber The mixture of one or more types of inks; it can also be one of silicone structural adhesives, polyurethane adhesives or organic silicon structural adhesives; corresponding to the reflective material powder 400 is yellow fluorescent powder and carbon dioxide A mixture of one or more of silicon, titanium dioxide, cornstarch or white PET fine powder.

[0047] In this embodiment, the reflective material powder 400 must contain yellow phosphor, so that the yellow phosphor and silicon dioxide, titanium dioxide, cornstarch or white PET fine powder form the reflective material powder 400 . Yellow phosphor has the property of absorbing blue light and converting it into backlight. When the edge of the quantum dot finished product leaks the blue edge, it means tha...

Abstract

Disclosed are a side edge reflecting plate attaching process of a light guide plate (100) and a light guide plate (100). The process comprises: adding reflective material powder (400) to a transparent liquid viscous raw material (300) to blend to form a liquid viscous reflecting material, wherein the mass percent of the reflective material powder (400) is not less than 15% and not more than 45%; coating a sheet base material with the liquid viscous reflecting material to form a sheet film reflecting material; attaching the sheet film reflecting material to an end face of the light guide plate (100); and solidifying the sheet film reflecting material on the end face of the light guide plate (100).

Description

technical field [0001] The invention relates to the field of liquid crystal display backlight modules, in particular to a process for attaching side reflection sheets of a light guide plate and a light guide plate. Background technique [0002] In order to optimize the optical utilization of the side-lit backlight module more efficiently, the non-light-incident side end surface of the light guide plate (LGP) needs to be processed and attached with a side reflector with a certain reflectivity. The currently used side reflectors mainly use white or silver substrates as the reflective layer. The reflective surface of the reflective substrate is processed with a certain thickness and transparent adhesive layer, which is attached to the light guide plate through the adhesive layer. The non-light-incident end surface realizes the optimal utilization of the light efficiency of the side-lit backlight module. However, in the actual product processing and application of such side ref...
