This study proposed temperature control functions during the attaching process using the preheating operations of pressure sensitive adhesives and a pre-existing warp polarizer plate. The polarizer plate is softened evenly, and, then, the bubbles can be discharged smoothly in the attaching process. Three main control factors are used in the polarizer plateĀ  attachment process, using an experimental design method, to determine the best combination of parameters. By applying optimal parameters in the experiments, bubble width can be decreased by 60.49%, compared with that of the previous process.
