Problems solved by technology

[0007] However, when the upper and lower optical sheets are bonded in this way, it is difficult to press the upper and lower optical sheets using conventional rollers due to the structured pattern formed on the top surface of the upper optical sheet.
[0008] In particular, when conventional rollers cannot be used to press the upper and lower optical sheets, it is difficult to sufficiently press the upper and lower optical sheets and have a uniform distance when bonding the upper and lower optical sheets , and thus reduces the quality of the optical sheet module

Abstract

The present invention relates to a method for manufacturing an optical sheet module, and the method comprises: a first pattern formation step of coating a top surface of a first base film with a liquid-state source material so as to form a first structured pattern; a provisional pattern curing step of semi-curing the first structured pattern while maintaining its shape; an adhesive layer coating step of coating a surface of a second base film with an adhesive layer; a provisional adhesive layer curing step of semi-curing the adhesive layer coated on the second base film; an adhesion step of adhering at least a part of the first structured pattern of the first base film to a bottom surface of the second base film; and a main curing step of curing the first structured pattern while the firstbase film and the second base film are adhered.

Description

technical field [0001] The present invention relates to a method and an apparatus for manufacturing an optical sheet module, and more particularly, to a method and an apparatus for manufacturing an optical sheet module capable of easily bonding a plurality of optical sheets and having improved bonding quality. Background technique [0002] Liquid crystal display devices are display devices used in laptop computers, desktop computers, smartphones, televisions, and the like. As the demand for liquid crystal display devices increases, the characteristics of the liquid crystal display devices also change and improve year by year. [0003] A liquid crystal panel of a liquid crystal display device which is a non-light-emitting device requires a backlight unit due to its structure. The backlight unit is composed of various optical systems. In addition, the backlight unit uses a periodic array of optical films to improve brightness. [0004] Referring to a conventional method of ...
