Description
Technical field
The present invention relates to carry out the method that stamping-out is made optical film product by sheet material or long paper to blooming.
Background technology
With light polarizing film, optical compensation films, phase shift films (phasic difference Off イ Le system), optical reflection film and light-diffusing films is the blooming of example and with the layered product that at least one piece of lamination of these films forms, and is the important optics that constitutes liquid crystal indicator.These bloomings normally cut off with the display frame size conforms of liquid crystal cell, mainly are as the optical film product of rectangle and produce.In addition, with the optical film product of rectangle, in the table and up and down, to be that optical axis alignment is carried out the situation that overlapping back produces as overlapping body a lot.
Fig. 1 represents to use blanking knife model (to play ち Omission き Blade type) make the synoptic diagram of the method for optical film product by the sheet material of blooming.The blanking knife model (3) that uses desired size carries out stamping-out to the sheet material (2) of blooming, obtains optical film product (1).
Fig. 2 represents to use blanking knife model to be made the synoptic diagram of the method for optical film product by the long paper of blooming.The blanking knife model (3) that uses desired size carries out stamping-out to the long paper (4) of blooming, obtains optical goods (1) (for example, with reference to patent documentation 1,2.)。
The optical film product of stamping-out is perhaps asymmetric up and down owing to asymmetric in the table like this, at this moment just requires in the his-and-hers watches, distinguishes up and down.
About distinguishing in the table, for example, there is not necessity of distinguishing in special the showing owing to symmetry in the table of single Polarizer and phase shift films.But, for the actual optical film product of producing form, through regular meeting's configuration protection film on single face, at the adhesive coating (pressure-sensitive adhesive) of its opposing face configuration with the stripping film protection.At this moment, since asymmetric in the table, necessity of distinguishing in the table is arranged.In addition, the layered product of a plurality of bloomings of lamination also often has asymmetric situation in the table, distinguishes it also is necessary in the table.
For discriminating conduct in the table of optical film product, there was cross section with goods to utilize magnifier to amplify in the past and distinguishes, observe the film surface in the goods table is compared and distinguishes or distinguish from the case of bending of goods based on the difference of gloss difference and light scattering.But these methods all are the methods of requirement skill level, are not simple discriminating conduct.For this reason, just be necessary to develop discriminance in the easy table that does not need special technology.
In addition, also to seek method that optical film product is distinguished up and down.The direction that original optical axis with optical film product is set in the liquid crystal indicator that is suitable as purpose is very necessary.For this reason, when making optical film product as starting material, need carry out stamping-out with certain angle with respect to the sheet material of blooming or the datum line of long paper with the sheet material of blooming or long paper.
The optical axis here is meant that the optics rerum natura reaches maximum or minimum, perhaps shows the direction of maximum value or minimum value.Can enumerate light transmission rate, refractive index, mist degree, phase differential, tone etc. as the optics rerum natura.
Expression has the optical axis key diagram of the optical film product of the optical axis in face among Fig. 3.General, the optical axis of blooming (5) is in the face of blooming and during normal direction, even the optical film product of stamping-out rotates up and down, the optical axis of optical film product does not have the variation of essence yet.
The optical axis key diagram of the optical film product when on the other hand, the optical axis of expression blooming is in the face of blooming and beyond normal direction among Fig. 4.Under the situation of the optical axis of blooming (6) in the face of blooming and beyond the normal direction, when the optical film product of stamping-out rotated up and down, the optical axis of optical film product also rotated up and down.For this reason, in the face of optical axis at blooming of blooming and the blooming beyond the normal direction during, just be necessary on optical film product, to be provided with the mark of several expression optical axis directions as starting material.
In a large amount of productions of optical film product, adopt long paper with blooming as starting material more, use the blanking knife model continuous stamping to become the stamping-out method for making of desired size.
Be illustrated in the synoptic diagram of the method for setting-out on the long paper of blooming of existing method among Fig. 5, Fig. 6.The optical axis of blooming adopts setting-out in advance (7) on the long paper of blooming in face and beyond the normal direction time more, or the method (with reference to patent documentation 3,4) of setting-out in the long paper of extraction blooming.The optical film product that obtains like this, the variation of line position just can be distinguished its rotation (Fig. 5) easily when rotating up and down.But, when the optical film product after the setting-out is carried out stamping-out, must make line as much as possible the end by optical film product so that this line central authorities by optical film product not.If line is by the central authorities of optical film product, then when optical film product rotates up and down, because line just can not easily be distinguished its rotation (Fig. 6) once more by blooming central authorities.
The method of setting-out on the blooming long paper like this is because easy can preferably the employing.But, also having owing to the goods that do not have line have in a large number been made in the loss of not noting pen (8), these are handled as substandard products owing to not distinguishing in the table or up and down.And, when replacing, all must stop manufacturing process at every turn and be related to the reduction of production efficiency.Because these reasons, expectation is developed the method that substitutes setting-out and mark easily is set, and yield is made the method for optical film product really well.
