Film roll manufacture method and manufacturing installation and film roll

Technical field

The present invention relates to film roll (film roll) manufacture method and manufacturing installation and film roll, particularly be used in the manufacturing of display panels such as Liquid Crystal Display (LCD) and OLED display, constitute the coiling technology of the film substrate (film substrate) of film roll.

Background technology

In recent years, in fields such as Liquid Crystal Display (LCD) and OLED display, developing soft display panel with flexible substrates such as plastic bases.In the manufacturing of this soft display panel,, preferably adopt the expansion that to handle the flexible substrate continuously to twine (roll-to-roll) mode from the production performance aspect.

Owing to launch in the canoe at this, the for example long film substrate of hundreds of rice is wound on unwind roll (delivery roll) and the winding roller (take-up roll), therefore probably can be because of being in contact with one another between the film substrate surface, perhaps foreign matter is sneaked into the coiling under the state, and film of being formed on substrate surface etc. is caused damage.

So, proposed in order not allow the film substrate surface be in contact with one another, and the limit providing spacer to film substrate, limit coiled film substrate is made the such method of film roll.

For example, disclose the limit and provide spacer to the both ends of transparent conducting film in patent documentation 1, the limit allows transparent conducting film be wound on the manufacture method of the conductive membrane roller on the roller core.So, the spacer owing to passing through to be provided reduces the pressure that is applied on the transparent conducting film, even therefore have foreign matter to sneak between the film, also is difficult to produce the scar by foreign matter caused in conductive membrane.

Patent documentation 1: TOHKEMY 2004-199643 communique

But, because in the manufacturing of soft display panel, implements meticulous patterning, therefore probably can be because of being in contact with one another between the film substrate surface, and the conducting element that is formed on substrate surface etc. is suffered damage, make display quality decline.For example, when as patent documentation 1, only when the configuration isolation thing of the both ends of film substrate, probably can be in contact with one another between the substrate surface because of the bending of substrate self etc. makes, cause the conducting element of substrate surface to suffer damage, the display quality of display panel descends.

Though in order to solve such problem, expected increasing the method for spacer thickness, because the part that this spacer thickness increased can cause the increase by the film roll diameter of coiled film substrate manufacturing, the therefore maximization that has brought manufacturing installation.Because the maximization meeting of such manufacturing installation becomes the problem of particular importance in the vacuum types manufacturing installation, therefore had better not increase the thickness of spacer.
