Abstract

An optical panel manufacturing apparatus is disclosed. The disclosed optical panel manufacturing apparatus can include: a film separation unit for separating an optical film from a laminate of a release film and the optical film; a film measurement unit for measuring a first position, which is the position of a front end of the optical film separated by the film separation unit in a first direction, and a second position, which is the position thereof in a second direction different from the first direction; and a control unit for adjusting the position of a panel attached to the optical filmon the basis of the position of the front end of the optical film measured by the film measurement unit.

Description

technical field [0001] The invention relates to a method and equipment for manufacturing an optical panel. More specifically, the present invention relates to an apparatus for manufacturing optical panels that can bond optical films to the panels at precise locations. Background technique [0002] Generally, as a type of optical panel, a liquid crystal panel corresponds to a display portion of a liquid crystal display, and is manufactured by bonding an optical film having a polarizing layer to a panel having a rectangular shape. [0003] Such methods of manufacturing liquid crystal display panels are classified into a sheet-to-panel (STP) type method in which a sheet of an optical film is bonded to the panel; and a roll-to-panel (RTP) type method A method in which an optical film is supplied wound on a roll and bonded to a panel. [0004] In the RTP type method, an optical film bonded to a release film by means of an adhesive is continuously unrolled from a roll, detached ...
