Abstract
A method is provided for removing a polarizing sheet with a tool that includes a handle including a main body forming therein a channel for receiving adhesive dissolving liquid, a piston device mounted inside the channel, and a guide tube mounted on the main body, and a blade mounted to the handle. The guide tube has an end in communication with the channel and an opposite end positioned on the blade to guide the adhesive dissolving liquid from the channel to the blade. The polarizing sheet is removed by lifting up a portion of the polarizing sheet and placing the blade against bonding adhesive between the polarizing sheet and a substrate to which the polarizing sheet is attached to allow the adhesive dissolving liquid to be guided by the guide tube toward the blade for subsequently flowing toward and dissolving bonding adhesive.
