본 발명은 3차원 영상을 나타내도록 하기 위한 3차원 영상장치에 사용되는 패러랙스 배리어 패널 제조방법 및 이 방법에 의하여 제조된 패러랙스 배리어 패널에 관한 것이다.The present invention relates to a method for manufacturing a parallax barrier panel used in a 3D imaging apparatus for displaying a 3D image, and a parallax barrier panel manufactured by the method.

종래 3차원 영상을 나타내도록 하는 3차원 영상장치로서는 도 9에 도시한 바와 같이 평면 디스플레이 패널(LCD 패널, PDP패널, EL 패널)과 같은 표시부재(1)의 전면에 패러랙스 배리어(2)와 개구부(3)가 번갈아 배열된 패러랙스 배리어 패널을 설치한 것이 사용되고 있는데, 상기 표시부재(1)에서 좌안용 영상은 홀수열에만 표시되고, 우안용 영상은 짝수열에만 표시되게 하면, 좌안에는 좌안용 영상(L1~L7)이 개구부(3)를 통하여 보여지고 우안용 영상(R1~R7)은 패러랙스 배리어(2)에 의하여 차단되며, 우안에는 우안용 영상(R1~R7)이 개구부(3)를 통하여 보여지고 좌안용 영상(L1~L7)은 패러랙스 배리어(2)에 의하여 차단되게 된다. 따라서, 관찰자는 좌안 우안이 각각 다른 영상을 보게 되기 때문에 3차원 영상을 감상할 수 있다.As a three-dimensional imaging apparatus for displaying a conventional three-dimensional image, as shown in FIG. 9, a parallax barrier 2 and a front surface of the display member 1, such as a flat panel display panel (LCD panel, PDP panel, EL panel), A parallax barrier panel in which the openings 3 are alternately arranged is used. In the display member 1, when the left eye image is displayed only in odd rows and the right eye image is displayed only in even rows, the left eye is left. The eye images L1 to L7 are shown through the opening 3, the right eye images R1 to R7 are blocked by the parallax barrier 2, and the right eye images R1 to R7 are the opening 3. ) And the left eye images L1 to L7 are blocked by the parallax barrier 2. Therefore, the observer can enjoy the 3D image because the left eye of the right eye sees a different image.

그런데, 여기에 사용되는 패러랙스 배리어 패널이 2종류가 사용되고 있다. 한가지는 전자 셔터형태의 TN 패널인데, 이것은 그 구조 및 제조 공정이 매우 복잡하여 가격이 매우 비싸고, 다른 하나는 격자 구조의 현상 필름 형태를 투명 기판에 투명 접착제와 함께 접착하여 사용하기도 하는데, 이 방법도 역시 필름 제작비용이 고가이고, 투명 상태 유지나, 접착시 불량이 발생하여 패러랙스 배리어 패널 제조가격이 높아지는 단점이 있다.By the way, two types of parallax barrier panels used here are used. One is an electronic shutter-type TN panel, which is very expensive due to its complicated structure and manufacturing process, and the other is to use a lattice-like developing film in combination with a transparent adhesive to a transparent substrate. In addition, the film production cost is expensive, there is a disadvantage that the maintenance of the transparent state, a failure occurs during the adhesion to increase the manufacturing price of the parallax barrier panel.

따라서 본 발명은 상기한 종래의 문제점을 해결하기 위해 안출된 것으로, 간단한 방식으로 저렴한 가격으로 제조할 수 있는 패러랙스 배리어 패널 제조방법 및 이 방법에 의하여 제조된 패러랙스 배리어 패널을 제공하고자 함에 그 목적이 있다.Accordingly, an object of the present invention is to provide a method for manufacturing a parallax barrier panel and a parallax barrier panel manufactured by the method, which can be manufactured at a low price in a simple manner.

그 후, 도 3에 도시한 바와 같이 상기 포토레지스트 막(20) 상에 마스터 필름(30)을 올려놓고 상기 포토레지스트 막(20)을 노광 및 현상하여, 도 4에 도시한 바와 같이 포토레지스트 패턴(20)을 형성한다. 이와 같이 하여 실크인쇄용 망사를 준비한다. 이 망사를 위에서 보면 도 5에 도시한 바와 같이 포토레지스트 패턴(20)이 일정 간격을 두고 평행하게 형성되어 있다.Thereafter, as shown in FIG. 3, the master film 30 is placed on the photoresist film 20, and the photoresist film 20 is exposed and developed. As shown in FIG. 4, the photoresist pattern is illustrated. 20 is formed. In this way, a silk printing mesh is prepared. When the mesh is viewed from above, as shown in FIG. 5, the photoresist patterns 20 are formed in parallel at regular intervals.

이어, 도 6에 도시한 바와 같이 상기 인쇄용 망사를 투명기판(40)상이 올려놓고 전체 표면을 불투명성 흑색잉크가 공급되며, 스퀴지(50)를 밀착 이동시킴으로써, 상기 망사의 포토레지스트막(20)이 존재하지 않는 부분에 대응하는 투명기판(40)의 영역에만 상기 불투명성 잉크가 도포되도록 한다. 따라서, 도 7 및 도 8에 도시한 바와 같이 투명기판(10)상에 일정간격을 두고 형성된 불투명성 잉크막(70)이 형성된다. 여기서, 상기 투명기판의 재질로서는, 유리, 아크릴, 무연신 폴리카보네이트인 것이 바람직하고, 상기 불투명성 잉크로서는 예를 들면 불투명한ABS계 잉크 및 PET계 잉크를 사용하면 된다.Subsequently, as shown in FIG. 6, the transparent mesh 40 is placed on the printing mesh, and an opaque black ink is supplied to the entire surface thereof. The opaque ink is applied only to the region of the transparent substrate 40 corresponding to the portion not present. Thus, as shown in FIGS. 7 and 8, an opaque ink film 70 formed at a predetermined interval on the transparent substrate 10 is formed. Here, the material of the transparent substrate is preferably glass, acrylic or non-stretched polycarbonate, and as the opaque ink, for example, opaque ABS ink and PET ink may be used.

The light does not pass through the portion where the opaque ink exists, and the light passes only through the portion where the opaque ink does not exist. As shown in FIG. 9, the parallax barrier panel manufactured above is installed on the front of the display member 1 such as a flat panel display panel (LCD panel, PDP panel, EL panel) 1 so as to match the pitch of pixels. In the flat panel display panel (LCD panel, PDP panel, EL panel) (1), when the left eye image is displayed only in odd rows and the right eye image is displayed only in even rows, the left eye image (L1 to L7) Through the opening 3, the right eye images R1 to R7 are blocked by the parallax barrier 2, and the right eye images R1 to R7 are seen through the opening 3 and the left eye The dragon images L1 to L7 are blocked by the parallax barrier 2. Therefore, the observer can enjoy the 3D image because the left eye of the right eye sees a different image.
