METHOD OF MANUFACTURING OPTICAL DISPLAY UNIT AND MANUFACTURING SYSTEM OF OPTICAL DISPLAY UNIT

摘要

Provided are a method of manufacturing an optical display unit and a manufacturing system of the optical display unit wherein in the case of sticking an optical film to an optical display substrate, a defective optical film is eliminated optimally and precision of the elimination can be confirmed. The method is characterized in that in the process of conveying sheet product, a predictive conveyance distance when conveying positional identification information provided to the sheet product from a first position upstream in the conveyance to a second position downstream of the first position in the conveyance is compared with a measured conveyance distance from the first position to the second position obtained by detecting the positional identification information by use of a detection means respectively at the first position and the second position, and the conveyance processing of the sheet product is corrected so that the measured conveyance distance is within the predetermined range of the predictive conveyance distance.
