no. 1 approach

[0091] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In this embodiment, as a production system of an optical display device, a film bonding system constituting a part thereof will be described.

[0092] figure 1 It is a schematic configuration diagram of the film bonding system 1 of this embodiment. The film bonding system 1 bonds film-shaped optical members such as polarizing films, retardation films, and brightness enhancement films to panel-shaped optical display components such as liquid crystal panels and organic EL panels, for example. The film bonding system 1 is comprised as a part of the production system which produces the optical display device containing the said optical display component and an optical member. In the film bonding system 1, liquid crystal panel P is used as the said optical display component. exist figure 1 In the figure, for convenience of illustration, the film bonding system 1 i...

no. 2 approach

[0250] Hereinafter, another embodiment of the present invention will be described with reference to the drawings. In this embodiment, as a production system of an optical display device, a film bonding system constituting a part thereof will be described.

[0251] Figure 16 It is a schematic block diagram of 1 A of film bonding systems of 2nd Embodiment. exist Figure 16 In FIG. 2 , the same reference numerals are assigned to the same components as those of the first embodiment, and detailed description thereof will be omitted. In addition, regarding the first embodiment Figure 2 ~ Figure 4 The content of this embodiment also has common content, so its description will be omitted.

[0252] It should be noted that, in this embodiment, the first optical member F11, the second optical member F12, and the third optical member F13 pass through the first sheet F1m, the second sheet F2m, and the third sheet F3m described later (hereinafter, It is sometimes referred to as a she...

no. 3 approach

[0331] Figure 20 It is a schematic configuration diagram of the film bonding system 2 of the third embodiment.

[0332] In this embodiment, it differs from 2nd Embodiment in that the conveyance direction of the 1st optical member sheet|seat F1, the conveyance direction of the 2nd optical member sheet F2, and the conveyance direction of the 3rd optical member sheet F3 are mutually parallel. Therefore, in this embodiment, the same reference numerals are assigned to the same components as those in the second embodiment, and detailed description thereof will be omitted.

[0333] It should be noted that, in Figure 20 In , the structures of the rotary index plates 11, 16 and the bonding devices 13, 15, 18 arranged in their peripheral parts are schematically shown. exist Figure 20 in, omit Figure 17 A representation of the main conveyor 5, the secondary conveyors 6 and 7, and the film stripping device 14 etc. is shown. exist Figure 20 Among them, the arrows shown in the firs...

Abstract

The invention provides a production system for an optical display device and a production method for an optical display device. The production system for the optical display device includes: a stage (39) which supports a liquid-crystal panel (P); an unwinding portion (31a) which unwinds an optical member sheet (F1); a control device which acquires in-plane distribution data of optical axes in the optical member sheet (F1) and adjusts a cutting direction; a first cutting device (31b) which cuts the optical member sheet (F1) in larger size than a display region (P4); a peeling portion (31c) which peels a sheet piece (F1m) from a separator sheet (F3a); a laminating head (32) which holds and tilts the sheet piece (F1m); a driving device which relatively moves the laminating head (32) and a table (39) so that a cutoff side of the sheet piece (F1m) and one side of the liquid-crystal panel (P) are matched or are mutually in parallel; a detecting device which detects an outer peripheral edge of a laminated surface between the sheet piece (F1m) and the liquid-crystal panel (P); and a second cutting device (50) which cuts off an opposite part that is a part of the sheet piece (F1m) opposite to the display region (P4) from a surplus part at an outside of the opposite part.

Description

technical field [0001] The invention relates to a production system of an optical display device and a production method of the optical display device. [0002] this application claims priority based on Japanese Patent Application No. 2013-105587 for which it applied on May 17, 2013, and uses the content here. Background technique [0003] Conventionally, in the production system of optical display devices such as liquid crystal displays, optical members such as polarizing plates bonded to liquid crystal panels (optical display components) have sometimes been cut from long films into sheets of a size that fits the display area of ​​the liquid crystal panel. It is bonded to a liquid crystal panel after being packed and conveyed to another production line (for example, refer patent document 1). [0004] For example, the sheet is obtained by using a long optical film as a raw material and cutting the optical film into a rectangle with a cutting blade. [0005] Figure 15 It i...
