Description

배향막 형성을 위한 전사판{APR plate for coating alignment layer}Transfer plate for forming an alignment layer {APR plate for coating alignment layer}

본 고안은 전사판에 관한 것으로서, 특히 액정표시장치의 기판에 형성된 액티브 영역 상에 배향막을 형성시키기 위한 전사판에 관한 것이다.The present invention relates to a transfer plate, and more particularly, to a transfer plate for forming an alignment layer on an active region formed in a substrate of a liquid crystal display device.

일반적으로 LCD (Liquid Crystal Display)라고 지칭되는 액정 디스플레이 장치는 전압을 인가함에 따라 변화하는 액정의 광학 성질을 이용하여 상(Image)을 표현하는 것으로, 한 쌍의 글래스 기판과 글래스 기판 사이에 주입된 액정으로 이루어진 액정 패널과, 액정 패널에 전기 신호를 인가하기 위한 인쇄회로기판(PCB) 등으로 이루어져 있다.A liquid crystal display device, commonly called an LCD (Liquid Crystal Display), expresses an image by using an optical property of a liquid crystal that changes as a voltage is applied, and is injected between a pair of glass substrates and a glass substrate. It consists of a liquid crystal panel made of liquid crystal and a printed circuit board (PCB) for applying an electrical signal to the liquid crystal panel.

액정 디스플레이 장치에 있어서 균일한 밝기와 높은 대비비(Contrast Ratio)를 얻기 위해서는 액정 패널내의 액정 분자들이 일정한 방향으로 배열되어야 한다. 이와 같이 액정 분자들을 일정한 방향으로 배열시키기 위한 목적으로 폴리이미드(Polyimide)와 같은 배향제를 기판위에 코팅하여 배향막을 형성한다.In the liquid crystal display device, in order to obtain uniform brightness and high contrast ratio, the liquid crystal molecules in the liquid crystal panel should be arranged in a certain direction. As described above, an alignment agent such as polyimide is coated on the substrate for the purpose of aligning the liquid crystal molecules in a predetermined direction to form an alignment layer.

기판 위에 배향막을 형성하기 위하여는, 도 1에 도시된 바와 같이, 디스펜서(50;Dispenser)로 폴리이미드를 아니록스 롤(30;Anilox Roll)상에 배출한다. 배출된 폴리이미드는 닥터 블레이드(40;Doctor Blade)에 의해 아니록스 롤(30)상에 얇고 균일하게 도포된다. 도포된 폴리이미드는 미리 패터닝된 전사판(60;APR Plate)에 인쇄되고, 전사판(60)에 인쇄된 폴리이미드는 코팅 롤(20;Coating Roll)에 의해 기판(10)에 코팅되어 배향막이 형성된다.In order to form the alignment film on the substrate, as shown in FIG. 1, the polyimide is discharged onto the Anilox Roll with a dispenser 50. The discharged polyimide is applied thinly and uniformly on the anilox roll 30 by a doctor blade 40. The applied polyimide is printed on a pre-patterned transfer plate 60 (APR Plate), and the polyimide printed on the transfer plate 60 is coated on the substrate 10 by a coating roll 20 to form an alignment layer. Is formed.

이와 같이, 기판 위에 배향막을 형성하기 위해서는 중합체 물질로 이루어진 전사판(APR plate;Asai Kasei Photosenstive Resin Plate)이 이용된다. As such, in order to form the alignment layer on the substrate, an ASR plate (Asai Kasei Photosenstive Resin Plate) made of a polymer material is used.

종래 기술에 따른 배향막 형성을 위한 전사판은, 도 2에 도시된 바와 같이, 고무계 물질의 베이스 필름(62;Base Film)과 APR층(64)으로 이루어진 2층 구조이며, APR층(64)에는 망점이 형성된 액티브 영역이 마련된다. 이 액티브 영역은 기판의 액티브 영역에 배향막을 형성시키기 위한 영역으로, 이 부분에 폴리이미드가 도포되어 기판에 배향막을 형성시킨다.The transfer plate for forming the alignment layer according to the prior art, as shown in Figure 2, has a two-layer structure consisting of a base film (62) of the rubber-based material and the APR layer (64), the APR layer (64) An active region in which a dot is formed is provided. This active region is a region for forming an alignment film in the active region of the substrate, and polyimide is applied to this portion to form the alignment film on the substrate.

그런데, 이와 같은 구조의 전사판에 의하면 폴리이미드 코팅 공정 중 적용된는 대상 모델의 크기가 변경될 때마다 사용하던 전사판을 제거한 후, 새로운 대상 모델의 크기에 맞는 전사판을 장착하여야 하므로, 그 교체 작업이 번거롭고, 시간이 많이 소요되며, 새로운 전사판을 구입해야 하는 등 비경제적인 문제점이 있다.However, according to the transfer plate having such a structure, the transfer plate applied during the polyimide coating process needs to be removed after the transfer plate is used whenever the size of the target model is changed, and then the transfer plate suitable for the size of the new target model is installed. This is cumbersome, time consuming, and uneconomical, such as the need to purchase a new transfer plate.

본 고안은 상기의 문제점을 해결하기 위하여 창출된 것으로서, 대상 모델의 크기 변화에 맞추어 경제적으로 사용할 수 있는 개선된 전사판을 제공하는 것을 그 목적으로 한다.The present invention was created to solve the above problems, and an object thereof is to provide an improved transfer plate that can be used economically in accordance with the size change of the target model.

상기의 목적을 달성하기 위한 본 고안의 전사판은, 일면에 다수의 홈이 서로 이격되어 형성된 바디; 및 상기 바디의 홈에 끼워 맞춤식으로 결합되도록 타면에 돌기가 형성된 액티브 플레이트를 포함한다.Transfer plate of the present invention for achieving the above object, a plurality of grooves formed on one surface spaced apart from each other; And an active plate having protrusions formed on the other surface thereof to be fitted into the groove of the body.

여기서, 상기 액티브 플레이트의 일면에는 다수의 망점이 돌출되며, 상기 망점들 사이에 폴리이미드가 도포되는 것이 바람직하다.Here, a plurality of dots are projected on one surface of the active plate, and polyimide is preferably applied between the dots.

이하 첨부된 도면을 참조하면서 본 고안의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 고안의 일 실시예에 따른 전사판을 나타낸 사시도이다.3 is a perspective view showing a transfer plate according to an embodiment of the present invention.

도면을 참조하면, 배향막을 형성하기 위한 전사판(100)은 바디(110)와 액티브 플레이트(active plate;120)를 포함한다.Referring to the drawings, the transfer plate 100 for forming the alignment layer includes a body 110 and an active plate (120).

바디(110)는 일면에 다수의 홈(111)이 소정 간격을 두고 서로 이격 형성된다. 여기서, 다수의 홈(111)은 삼각형, 사각형, 타원형 등 다각형 형태로 다양하게 형성될 수 있다.The body 110 is formed with a plurality of grooves 111 spaced apart from each other at a predetermined interval on one surface. Here, the plurality of grooves 111 may be variously formed in a polygonal shape such as a triangle, a square, an ellipse, and the like.

액티브 플레이트(120)는 다양한 크기로, 바디(110)에 형성된 다수의 홈(111)에 착탈 가능하도록 타면에 돌기(121)가 돌출된다. 이 돌기(121)는 바디(110)에 형성된 홈(111)과 끼워 맞춤식으로 결합되기 위하여 홈(111)의 형상과 동일한 형상을 가지며, 또한 끼워 맞춤식으로 결합 및 결합된 상태로부터 빼내기 용이하도록 탄력부재로 이루어진다.The active plate 120 has various sizes, and protrusions 121 protrude from the other surface of the active plate 120 to be detachable from the plurality of grooves 111 formed in the body 110. The protrusion 121 has the same shape as the shape of the groove 111 to be fit-fitted with the groove 111 formed in the body 110, and also an elastic member so as to be easily pulled out of the fit and coupled state. Is made of.

그리고 액티브 플레이트(120)의 일면에는, 즉 기판(미도시)의 액티브 영역에 접촉하는 면에는 다수의 망점(122)이 돌출되어, 이 망점들(122) 사이의 공간에 폴리이미드가 도포되어 기판의 액티브 영역에 배향제를 도포한다.In addition, a plurality of meshes 122 protrude from one surface of the active plate 120, that is, a surface contacting the active region of the substrate (not shown), and a polyimide is applied to a space between the meshes 122 to form a substrate. An aligning agent is apply | coated to the active area of this.

이와 같은 구조의 전사판(100)에 의하면, 대상 모델의 크기가 변화된 경우, 이전에 바디(110)에 결합되어 있는 액티브 플레이트(120)를 빼낸 후, 대상 모델의 크기에 맞는 액티브 플레이트(120)만을 교체하여 바디(110)에 끼우면 되므로, 그 교체가 용이하고, 경제적인 장점이 있다.According to the transfer plate 100 having such a structure, when the size of the target model is changed, the active plate 120 previously removed from the body 110 is removed, and then the active plate 120 suitable for the size of the target model. Since only replace the bay to the body 110, the replacement is easy, there is an economic advantage.

여기서, 대상 모델이라 함은 배향막이 형성될 기판의 액티브 영역의 크기를 말한다.Here, the target model refers to the size of the active region of the substrate on which the alignment layer is to be formed.

상술한 바와 같이 본 고안의 전사판에 의하면, 대상 모델의 크기 변화에 따라, 액티브 플레이트의 크기만을 변화시켜 바디에 착탈 가능하게 결합시킬 수 있으므로, 대상 모델 변경 시마다 소요되는 시간과 노력 등을 절약할 수 있어 경제적인 효과를 제공한다.As described above, according to the transfer plate of the present invention, since the size of the target model changes only the size of the active plate and can be detachably coupled to the body, the time and effort required for each change of the target model can be saved. Can provide economic effect.

본 고안은 상기에 설명되고 도면에 예시된 것에 의해 한정되는 것은 아니며, 다음에 기재되는 청구의 범위 내에서 더 많은 변형 및 변용예가 가능한 것임은 물론이다.The present invention is not limited to the above described and illustrated in the drawings, of course, more variations and modifications are possible within the scope of the claims set out below.
