Method for producing fused light guide panel

Abstract

The purpose of the present invention is to provide a method for producing a fused light guide panel which imparts free forms and three-dimensional and dynamic movements to various indoor and outdoor advertisements, signboards, promotional materials, public structures, displays, indicators, and the like by implementing a thin screen using only a single light guide panel base without using a separate screen panel or an auxiliary diffuser plate. The method for producing a fused light guide panel according to the present invention comprises: a step of manufacturing a planar or three-dimensional transparent light guide panel base by means of an optical PMMA resin; an optical design step of applying CAD and optical design to the upper and / or lower surfaces of the transparent light guide panel base; a step of converting each optically designed file into an output file; a step of sending the converted files to a printer and spraying colored and colorless light-guide ink on the upper and / or lower surfaces of the transparent light guide panel base to form multiple light guide printing layers via simultaneous and / or sequential multiple rounds of digital printing; and a step of producing a light guide panel by disposing an LED light source on the side of the transparent light guide panel base.

Description

technical field [0001] The present invention relates to a method for preparing a fusion-type light guide plate, in particular, to a method for preparing a fusion-type light guide plate that can be used not only in various indoor and outdoor advertisements, bulletin boards, publicity materials, public objects, displays, signs Objects, etc., according to the optical design, the bending of the shape and pattern endows the display of light and free form, three-dimensional, and movement, and realizes the permeability of light-guiding ink, the convenience of production, and the visual orientation of customers according to the application. Background technique [0002] Generally speaking, a light guide panel (LGP, Light Guide Panel) is a component included in a backlight unit (BLU, Back Light Unit) of a liquid crystal display (LCD, Liquid Crystal Display), and is an optical component formed of the following transparent resin, the above-mentioned The transparent resin can be polymet...

Problems solved by technology

[0033] When ejected, every 1cm 2 The area requires 1 ton of injection pressure, so the existing technology is difficult to apply to 24 inches, especially in the light guide plate of 32 inches or more, which is used as a large-area TV light guide plate.

[0034] Moreover, the light guide plate formed with the light guide pattern prepared by injection has the disadvantage of being easily deformed because the heat distortion temperature is usually as low as 80° C.

[0035] On the other hand, in the conventional production method, that is, after the light guide plate is prepared by the injection process of fluid polymethyl methacrylate, or the material of the light guide plate is prepared by extrusion or casting process, additional light guide pattern processing is performed. The process of preparing the light guide plate has the above-mentioned respective disadvantages. In addition, there is also the problem that polymethyl methacrylate, which is expensive and in short supply, needs to be used as a raw material.
