Abstract: The present invention relates to a peeling bar, apparatus, and method for peeling a polarizing film from a panel. This invention can minimize friction between the peeling bar and the polarizing film since the peeled polarizing film is in contact with a front part of the peeling bar. The radius of a curved surface at the tip of the front part and an inclined upper surface of the front part are designed to minimize the Z-axis component of a shearing force applied to the polarizing film. Also, in order to equalize tension applied to the polarizing film in a peeling process, this invention makes both ends of the polarizing film closely adhere to the peeling bar. According to this invention, fracture of the polarizing film is prevented, and thereby the polarizing film can be stably peeled from the panel without fracture.
Abstract translation: 本发明涉及一种用于从面板上剥离偏光膜的剥离条，设备和方法。 由于剥离的偏光膜与剥离条的前部接触，本发明可以使剥离条和偏振膜之间的摩擦最小化。 前部前端的弯曲表面的半径和前部的倾斜的上表面被设计成使施加到偏振膜的剪切力的Z轴分量最小化。 此外，为了在剥离过程中平衡施加于偏光膜的张力，本发明使偏光膜的两端紧密地贴合在剥离条上。 根据本发明，可以防止偏光膜的断裂，从而能够将薄膜稳定地从面板上剥离而不断裂。
