Description
Technical field
The present invention relates to for the preparation of the device of optical sheet and use the optical sheet preparation method of this device.More specifically, the optical sheet preparation method who the present invention relates to use the volume to volume formula optical sheet preparation facilities of soft mode and use this device, in described device, in the pre-coating stage, adopt belt coating fluid filling unit, therefore can realize the productive rate higher than prior art, and the coating fluid remove bubble of can effectively annotating.
Background technology
Back light unit for liquid crystal display (LCD) comprises the optical sheet that promotes anaclasis and diffusion, to improve the uniformity and the brightness of light.These optical sheets can comprise diffused light diffusion sheet, be layered in diffusion sheet upper surface with the light of aggregation and spreading and light be passed to the prismatic lens of panel of LCD, and the screening glass of protection diffusion sheet and prismatic lens.
Conventionally, in order to strengthen their light diffusivity and brightness and other optical property, predetermined patterned process is carried out in the surface of these optical sheets.Recently, used volume to volume formula equipment to carry out on a large scale the patterning of optical sheet.
Volume to volume formula equipment can be divided into the hard pattern device that uses pattern metal mould and the soft pattern device that uses membranaceous mould.
Hard pattern device is difficult to form hemispherical microlens pattern, yet soft pattern device can advantageously generate the various patterns that comprise microlens pattern.
Yet, the in the situation that of soft pattern device, improve if the productive rate of optical sheet and make mould high-speed mobile, in pattern, can produce bubble, or there will be the insufficient injection because of coating fluid to cause irregular pattern form, thereby cause the grievous injury to product quality.Especially, for hemispherical microlens pattern, can further increase the weight of the generation of bubble.In order to address these problems, most of soft pattern devices are used coating fluid filling unit to carry out pre-coating before carrying out main coating.
Korean Patent discloses partly the annotate method of coating fluid of at least one compression roller of using for No. 887340, and described compression roller is by being squeezed to fluoropolymer resin the fluoropolymer resin of annotating in the pattern of film.Fig. 1 illustrates the optical sheet preparation facilities that uses compression roller.As shown in Figure 1, the structure of conventional optical sheet preparation facilities transmits the soft mode 20 of patterning when a part of home roll 100 of contact by home roll 100.When periphery when rotation of soft mode 20 along home roll 100, coating fluid filling apparatus 110 is filled into coating fluid in the pattern of soft mode 20.This operation is equivalent to main coating, and conventionally, soft mode 20 is carried out to pre-coating, carries out subsequently main coating.After completing the main coating of using coating fluid filling apparatus 110, by soft mode 20 and basement membrane 10 combinations.Particularly, the first roller 120 engaging with home roll 100 is pressed onto basement membrane 10 on soft mode 20, so that they are bonded to each other, subsequently, make film 11 sclerosis of gained combination and transmits along home roll 100.Again the film 11 after sclerosis is separated into the blooming 12 of soft mode 20 and patterning.In the case, by second roller 130, soft mode 20 is peeled off from the blooming 12 of patterning, and be sent to subsequently pre-coating device A.Pre-coating device A is comprised of deflector roll 140,141 and 142, so that soft mode 20 is sent to main apparatus for coating, i.e. and coating fluid filling apparatus 110 and engage the applicator roll 150,151 and 152 with pre-coating soft mode 20 with each deflector roll 140,141 and 142.Applicator roll 150,151 and 152 is set to receive the coating fluid from resin feeding container 160,161 and 162.After the precoated cloth apparatus A of soft roller 20 pre-coating, soft mode 20 rotates by home roll 100, thereby is transferred into coating fluid filling apparatus 110, and carries out secondary coating subsequently, i.e. main coating.
Yet the soft mode that the said method of use compression roller provides only has subsection contact area in each compression roller substrate, therefore need a plurality of compression rollers of extra installation with improvement productive rate.Use a plurality of rollers can increase equipment size, and during being coated with because roller is exposed to the risk that the external world causes exterior materials to be polluted.
