Abstract
The invention is applicable in the field of liquid crystal display, and provides a light guide plate manufacturing method. The method comprises the following steps of: manufacturing a light guide plate substrate; spraying UV (ultraviolet) ink to the non-incident side of the light guide plate substrate; and performing UV curing to the light guide plate substrate with UV ink sprayed to form a UV ink reflective layer adhered to the non-incident side. The UV ink reflective layer not only has higher reflection rate, but also has strong adhesive force and falling prevention, can maintain the high light utilization for the light guide plate for a long time so as to ensure the excellent quality of a backlight module. The light guide plate avoids the problems that the adhesive on a reflector on the lateral side of the traditional light guide plate overflows by heat, the base material of the reflector is yellowed and falls off, as well as damage and dirt of the light guide plate and folded reflector caused by manual assembly of the reflector in the traditional printed light guide plate manufacture procedure, and the like. Therefore, the yield of the light guide plate is improved, mass time, manpower and materials are saved, and the production efficiency is improved.
Description
Technical field
The invention belongs to field of liquid crystal display, relate in particular to a kind of method for making, light guide plate, backlight module and LCD of light guide plate.
Background technology
Light guide plate (LGP) is a kind of line source to be converted to the optical element of area source, places in the backlight liquid crystal display module more, is used for the light that light source sends is converted to than uniform surface light source, for display panels provides backlight.The molding mode of light guide plate mainly is the printing moulding, acrylic/polycarbonate (PC) sheet material that promptly utilizes optical grade is as base material, adopt have high reflectivity and not the macromolecular material of extinction (being commonly called as printing ink) stamp the leaded light site in acryl/PC sheet material bottom surface with screen printing technology.After the light that sends from light source entered LGP, when being mapped to each leaded light site, light was destroyed in the total reflection of sheet material inside, and reflected light can penetrate by light guide plate is positive toward all angles diffusion.Arrange by adjusting the site, can make the light guide plate uniformly light-emitting.
At present, in order to improve the light utilization in the LGP, prevent that light from penetrating from the LGP side, the side that does not have a light source at LGP sticks reflector plate usually, and reflector plate is made up of polymethylmethacrylate (PET) base material and adhesive glue two parts usually.But, light guide plate is in ageing process, adhesive glue between reflector plate and the light guide plate base material be heated easily overflow, the reflector plate base material is prone to bad phenomenon such as yellowing and shedding, so not only can't play the effect that improves light utilization, have a strong impact on the quality of backlight module on the contrary, and then influence display effect.
