Problems solved by technology

[0010] First, the front end of the film is not aligned accurately with the panel, so there is a high possibility that the film cannot be aligned accurately on the panel
[0011] Second, in the structure where the film is attached to the panel while removing the release paper, and the film is attached to the panel by pressing the roller, there is a reduction in the precision of the film attachment. Disadvantages that there is a high possibility of air bubbles between the panel and the panel
As a result, there are difficulties in the construction of the film attachment system

Embodiment Construction

[0026] Hereinafter, the film attaching system and the film attaching method according to the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0027] figure 1 It is a sectional view of the polarizing film unit used in the film attaching system of the embodiment of the present invention, figure 2 It is a cross-sectional view of a panel attached with a polarizing film by means of a film attaching system according to an embodiment of the present invention.

[0028] refer to figure 1 and figure 2 , the polarizing film unit (polarizing film unit) of the embodiment of the present invention is an optical film with optical anisotropy, including an upper polarizing film unit (upper polarizing film unit) 20 and a lower polarizing film unit (lower polarizing film unit) 40 . The upper polarizing film unit 20 and the lower polarizing film unit 40 can be defined as a first polarizing film unit and a second polarizing film un...

Abstract

The present invention relates to a film attaching system and a film attaching method. The film attaching system of the present invention includes: a first polarizing film attaching system and a second polarizing film attaching system; the first polarizing film attaching system includes: a panel The transfer part is used to transfer the panel to the first polarizing film attachment area, the film supply part is used to supply the first polarizing film unit, and the cutter is used to completely cut the first polarizing film unit transferred by the film transfer part. Adsorption cylinder, and release paper removal part; the first polarizing film unit completely cut by the cutter rotates a predetermined angle around the vertical axis before reaching the first film attaching area; in the first polarizing film attaching area, the second A suction cylinder rotates, and the panel moves, so that the first polarizing film in contact with the surface of the first absorption cylinder is attached to the first surface of the panel.

Description

[0001] related application [0002] This application claims priority from Korean Patent Application No. 10-2014-0026239 filed with the Korean Patent Office on Mar. 5, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a film attaching system and a film attaching method. Background technique [0004] The present invention relates to a system and a method for attaching a polarizing film to both surfaces of a panel in the process of manufacturing a display panel such as a liquid crystal display (LCD) module. A polarizing film is attached to the upper surface and the lower surface of the panel so that the upper surface and the lower surface of the panel have optical anisotropy (optical anisotropy). [0005] There are a sheet-to-panel method and a roll-to-panel method in conventional polarizing film attachment methods. [0006] The sheet-to-panel attachment method refers to the method of supplying and attac...
