Description

편광판 제조방법Polarizing Plate Manufacturing Method

본 발명은 입체화상 구현 및 데코레이션, 광고판등에 사용되는 편광판의 제조에 관한 것으로서, 특히 2개의 광축이 서로 이웃하여 임의의 각도를 갖도록 배열된 편광판의 제조방법에 관한 것이다.The present invention relates to the production of polarizing plates used in stereoscopic image implementation and decoration, advertising panels, and more particularly, to a method of manufacturing a polarizing plate arranged so that two optical axes are adjacent to each other at an arbitrary angle.

일반적으로 입체화상을 구현하기 위해서는 좌우측 눈이 감지하는 화상을 한 화면에 동시에 구현해야 하는데, 이때 적용되는 방법으로는 서로 다른 광축으로 편광된 빛을 광축이 직교하는 편광렌즈 2매로 제조된 안경을 착용하거나, 2개의 광축이 존재하는 편광판을 사용하므로써 양눈에 서로 다른 화상을 형성시켜 입체감을 느끼게 하는 것이다. 이 때 편광렌즈의 안경을 사용하는 방법은 모든 사람이 안경을 착용해야 하는 불편함 때문에 편광판을 사용하는 방법이 보다 활발히 연구되고 있다.In general, in order to realize a stereoscopic image, an image detected by the left and right eyes must be simultaneously implemented on one screen. In this case, a pair of glasses made of two polarized lenses having light polarized at different optical axes orthogonal to each other are worn. Alternatively, by using a polarizing plate having two optical axes, different images are formed on both eyes to make a three-dimensional impression. At this time, the method of using the glasses of the polarizing lens has been actively studied how to use the polarizing plate because of the inconvenience that everyone should wear glasses.

입체화상을 구현하기 위한 편광판은 편광안경과 동일하게 광축이 다른 두 영역이 일정한 패턴이 형성되어야 하는 조건이 있다.Polarizing plates for realizing stereoscopic images have a condition in which two regions having different optical axes are formed in the same pattern as polarized glasses.

일반적으로 편광판을 제조하는 방법은 폴리비닐알콜 필름을 이색성 염료 또는 요오드 이온으로 염색한 후 일축연신하는 방법이 알려져 있다. 이 경우 1개의 광축을 갖는 것이 일반적이며, 2개의 광축을 갖거나 2가지 이상의 편광특성을 갖기 위해서는 특별한 기법을 적용해야만 제조가 가능하다.In general, a method of manufacturing a polarizing plate is known to uniaxially stretch a polyvinyl alcohol film after dyeing with a dichroic dye or iodine ion. In this case, it is common to have one optical axis, and in order to have two optical axes or to have two or more polarization characteristics, it may be manufactured only by applying a special technique.

이러한 기법으로 주지된 것으로는 화학적인 처리방법과 모자이크 방법이 제안되어 있는데, 화학적인 처리방법은 산화제 또는 환원제를 편광판에 국부적으로 처리하는 방법으로 처리 경계면이 불명확하거나, 처리된 부분의 투과도 및 편광도등 편광특성의 변화를 줄수는 있지만 편광축의 각도를 변경할 수는 없는 단점이 있다. 또한, 모자이크 방법은 여러특성의 편광판 조각을 모아 이어붙여 제조하는 것으로 여러가지의 편광 특성을 모자이크 할 수는 있지만 수 작업으로 제조하므로 크기가 제한되고, 생산성이 떨어지는 문제가 있다.As a well-known method for this technique, a chemical treatment method and a mosaic method have been proposed. The chemical treatment method is a method of locally treating an oxidizing agent or a reducing agent to a polarizing plate. Although the polarization characteristics can be changed, there is a disadvantage that the angle of the polarization axis cannot be changed. In addition, the mosaic method is produced by collecting and attaching pieces of polarizing plates having various characteristics, but it is possible to mosaic various polarizing characteristics.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 편광특성이 우수하고 연속적으로 그 제조가 가능하여 생산성을 향상시킬 수 있는 새로운 편광판의 제조방법을 제공하는 것을 그 목적으로한 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a method of manufacturing a new polarizing plate which can improve the productivity by being excellent in polarization characteristics and continuously manufactured.
