Peeling bar for peeling polarizing film from panel, peeling apparatus and peeling method using the same

A peeling apparatus for peeling a polarizing film from a panel, the peeling apparatus comprising:

• a stage configured to place thereon the panel having the polarizing film attached thereto;
• a clamper configured to clamp a part of the polarizing film after it is peeled from the panel;
• a peeling bar comprising:
• a body part having a top surface and a bottom surface;
• and
• a front part protruded from the body part and having a lower surface, an upper surface, and a tip, wherein the lower surface is extended from the bottom surface of the body part forming the same surface, wherein the upper surface is inclined downwardly from the top surface of the body part, and wherein the lower and upper surfaces are connected with each other by the tip forming a curved surface of circular form having a diameter,
• wherein the peeling bar is configured to be moved on the polarizing film when the polarizing film is peeled from the panel, wherein the peeling bar is adjustable in height;
• and
• a controller configured to move at least one of the stage and the clamper to peel the polarizing film such that tension is uniformly applied to the polarizing film by preventing stress concentration at a peeling position of the polarizing film.

A peeling method for peeling a polarizing film from a panel, the peeling method comprising steps of:

• placing on a stage the panel having the polarizing film attached thereto;
• fixing a part of the polarizing film to a clamper after the part of the polarizing film has been peeled from the panel,
• wherein a peeling bar adjustable in height is located at a peeling position, the peeling bar comprising:
• a body part having a top surface and a bottom surface;
• and
• a front part protruded from the body part and having a lower surface, an upper surface, and a tip, wherein the lower surface is extended from the bottom surface of the body part forming the same surface, wherein the upper surface is inclined downwardly from the top surface of the body part, and wherein the lower and upper surfaces are connected with each other by the tip forming a curved surface of circular form having a diameter, and
• wherein the peeled polarizing film is in contact with a front part of the peeling bar;
• and
• peeling the polarizing film by moving at least one of the clamper and the stage, while keeping the polarizing film in contact with the front part of the peeling bar to reduce stress concentration at a peeling position of the polarizing film.
