Patent ID: 8038820

Claim:
A method of stacking a flexible substrate, comprising the steps of: preparing a carrier substrate; stacking an adhesive layer on the carrier substrate; stacking a flexible substrate on the adhesive layer using a laminating or pressing method; wherein the flexible substrate is capable of having at least one image display device formed upon it after being stacked on the adhesive layer; wherein the step of stacking the adhesive layer and the step of staking flexible substrate are performed by the laminating method using a laminator having an upper roller rolling over the adhesive layer or the flexible substrate, and a lower roller rolling under the carrier substrate or a lower support formed under the carrier substrate under inert atmosphere or vacuum, wherein the laminator is controlled by air pressure, wherein a gap between the upper roller and the lower roller is controlled by the air pressure range from 0.1 to 10 kg/cm 2 , which the gap between the upper roller and the lower roller having the air pressure range is maintained while the upper and lower roller rotate in a same radial direction; wherein the adhesive layer comprises a support, and adhesive agent layers formed on and under the support, and wherein the image display device is formed on the flexible substrate; and wherein the adhesive layer and the carrier substrate are removed jointly after the image display device has been formed on the flexible substrate.
