System and method for manufacturing optical display

Abstract

An object of the invention is to provide an optical display manufacturing system or method that allows an increase in the yield of an optical film, a reduction in cost and an improvement in inventory control. An optical display manufacturing system includes feeding means ( 11, 14 ) that feeds a belt and sheet-shaped product ( 3 ) having an optical film from a roll ( 4 ) of the belt and sheet-shaped product, detection means ( 12 ) that detects a defect of the belt and sheet-shaped product fed by the feeding means, cutting means ( 13 ) that cuts the belt and sheet-shaped product into individual sheet-shaped products based on the result of the detection, transfer means ( 16 ) that transports each of the sheet-shaped products from the cutting process to a sticking process, and sticking means ( 17 ) that sticks the transported sheet-shaped product to an optical display unit.

1 . An optical display manufacturing system, comprising:
 feeding means that feeds a belt and sheet-shaped product comprising at least an optical film as a component of the optical display from a roll of the belt and sheet-shaped product;   detection means that detects a defect of the belt and sheet-shaped product fed by the feeding means;   cutting means that cuts the belt and sheet-shaped product into individual sheet-shaped products based on a result of the detection by the detection means;   transfer means that transports each of the sheet-shaped products from the cutting means to a sticking process; and   sticking means that sticks the sheet-shaped product transported by the transfer means to an optical display unit as another component of the optical display, wherein   all of the means are placed on a continuous manufacturing line.   
     
     
         2 . The optical display manufacturing system according to  claim 1 , wherein
 the belt and sheet-shaped product has a pressure-sensitive adhesive for sticking to the optical display unit and a release film for protecting the pressure-sensitive adhesive, and   the system further comprises separating means that separates the release film from the belt and sheet-shaped product before the detection of a defect by the detection means and cleaning means that cleans the belt and sheet-shaped product from which the release film has been separated, before the detection of a defect by the detection means.   
     
     
         3 . The optical display manufacturing system according to  claim 1  or  2 , further comprising second detection means that detects a defect after the sticking by the sticking means. 
     
     
         4 . A method for manufacturing an optical display, comprising the steps of:
 feeding a belt and sheet-shaped product comprising an optical film as a component of the optical display from a roll of the belt and sheet-shaped product;   detecting a defect of the belt and sheet-shaped product supplied by the feeding step;   cutting the belt and sheet-shaped product into individual sheet-shaped products based on a result of the detection in the detecting step;   transferring each of the sheet-shaped products from the cutting step; and   sticking the sheet-shaped product transported by the transferring step to an optical display unit as another component of the optical display, wherein   all of the steps are performed on a continuous manufacturing line.
