그 중 액정을 이용하여 영상을 구현하는 액정 표시 장치가 있다.Among them, there is a liquid crystal display device which implements an image by using a liquid crystal.
일반적인 액정 표시 장치(liquid crystal display, LCD)의 액정 패널(liquid crystal panel)은 두 기판과 그 사이에 들어 있는 유전율 이방성(dielectric anisotropy)을 갖는 액정층을 포함한다.A liquid crystal panel of a general liquid crystal display (LCD) includes two substrates and a liquid crystal layer having a dielectric anisotropy therebetween.
액정층에 전계를 인가하고, 이 전계의 세기를 조절하여 액정층을 통과하는 빛의 투과율을 조절함으로써 원하는 화상을 얻는다. A desired image is obtained by applying an electric field to the liquid crystal layer and adjusting the intensity of the electric field to adjust the transmittance of light passing through the liquid crystal layer.
이러한 액정 표시 장치는 휴대가 간편한 평판 표시 장치(flat panel display, FPD) 중에서 대표적인 것으로서, 이 중에서도 박막 트랜지스터(thin film transistor, TFT)를 스위칭 소자로 이용한 TFT-LCD가 주로 이용되고 있다.Such a liquid crystal display device is a representative example of a flat panel display (FPD) that is easy to carry, and a TFT-LCD using a thin film transistor (TFT) as a switching element is mainly used.

본 발명의 일실시예에 따른 곡면 디스플레이 모듈 제조방법은 통상의 서로 마주하는 기판을 포함하는 평면 형태의 디스플레이 패널을 이용하여 원하는 곡면 형태의 곡면 디스플레이 패널로 형성한 후 광원부에 결합시키는 것이다.A method of manufacturing a curved display module according to an exemplary embodiment of the present invention includes forming a curved display panel having a desired curved surface shape using a flat display panel including opposing substrates, and bonding the curved display panel to the light source.
예를 들어, 서로 마주하는 기판 및 그 사이에 형성되는 액정 층을 포함하는 액정 디스플레이 패널을 이용하여 곡면 형태를 가지는 디스플레이 패널을 제조할 수 있다.For example, a display panel having a curved surface shape can be manufactured by using a liquid crystal display panel including a substrate facing each other and a liquid crystal layer formed therebetween.
먼저, 통상의 평면 형태의 액정 디스플레이 패널을 이용하여 곡면 디스플레이 패널을 제조하는 방법에 대해서 설명한다.First, a method of manufacturing a curved display panel using a liquid crystal display panel of a normal plane type will be described.
본 발명의 일실시예에 따른 곡면 디스플레이 패널(100)의 제조방법은 유리로 형성되며 서로 마주보고 있는 제1기판(111)과 제2기판(115), 그리고 이들 사이에 형성되어 있으며 두 기판(111, 115)에 대하여 수직 또는 수평으로 배향되어 있는 액정 분자를 포함하는 액정층(113)을 포함하는 평면 형태의 액정 디스플레이 패널(110)을 이용하여 원하는 곡면 형태의 패널부(110)를 제조한다.A method of manufacturing a curved display panel 100 according to an embodiment of the present invention includes a first substrate 111 and a second substrate 115 formed of glass and facing each other, A panel section 110 having a desired curved surface shape is manufactured by using a flat liquid crystal display panel 110 including a liquid crystal layer 113 including liquid crystal molecules aligned vertically or horizontally with respect to the liquid crystal display panels 111, .
이때 제1기판(111)은 박막 트랜지스터 기판(thin film transistor array panel)이라고도 불리며, 제2기판(115)은 컬러 필터 기판(color filter array panel)이라고 불리기도 한다.Here, the first substrate 111 may be referred to as a thin film transistor array panel, and the second substrate 115 may also be referred to as a color filter array panel.
한편, 도면에는 도시되지 않았으나, 두 기판(111, 115)의 가장자리에는 두 기판(111, 115)을 결합시키기 위한 물질로 이루어지고 액정이 채워지는 공간을 형성하는 밀봉재가 배치될 수 있으며, 이러한 밀봉재에 의해 채워진 액정이 새는 것을 방지할 수 있다.
Although not shown in the drawing, a sealing material may be disposed at the edges of the two substrates 111 and 115 to form a space filled with the liquid crystal, which is made of a material for bonding the two substrates 111 and 115, It is possible to prevent the liquid crystal filled by the liquid crystal panel 20 from leaking.
이하에서 첨부된 도 4 내지 도 11을 참조하여 본 발명의 일실시예에 따른 곡면 형태를 가지는 디스플레이 패널과 이를 이용한 곡면 디스플레이 모듈의 제조 방법을 단계적으로 설명한다.Hereinafter, a display panel having a curved surface according to an embodiment of the present invention and a method of manufacturing a curved display module using the same will be described in detail with reference to FIGS. 4 to 11 attached hereto.
먼저, 본 발명의 일실시예에 따른 곡면 디스플레이 패널 제조방법은 제1기판(111)과 제2기판(115)의 두께가 미리 설정된 두께로 감소되도록 외측 일부를 각각 깎아내는 단계를 포함한다(S100).First, a method of manufacturing a curved display panel according to an embodiment of the present invention includes cutting out portions of the first substrate 111 and the second substrate 115 such that the thickness of the first substrate 111 and the second substrate 115 is reduced to a predetermined thickness (S100 ).
도 4에 도시된 바와 같은 통상의 평면 형태의 액정 디스플레이 패널(110)의 제1기판(111)과 제2기판(115)의 외측면을 깎아냄으로써 도 5와 같은 형태가 되도록 한다.The outer surfaces of the first substrate 111 and the second substrate 115 of the liquid crystal display panel 110 of the conventional planar shape as shown in FIG. 4 are cut out to have a shape as shown in FIG.
이때 외측 일부를 깎아내는 단계에서 제1기판(111)과 제2기판(115)을 깎아내는 방법은 종래에 알려진 임의의 방법일 수 있다. 예를 들면, 기계적 연마 방식일 수도 있고 에칭(etching)액을 이용한 에칭 방식일 수도 있다.At this time, the method of carving out the first substrate 111 and the second substrate 115 in the step of cutting off the outer part may be any method known in the art. For example, it may be a mechanical polishing method or an etching method using an etching solution.
또한 제1기판(111)과 제2기판(115)의 외측 일부를 깎아낼 때, 곡면 형태에서 휘어지지 않는 부분의 가장자리 부분은 깎아내지 않을 수 있다. Further, when the outer portion of the first substrate 111 and the second substrate 115 is shaved, the edge portion of the portion that is not curved in the curved surface shape may not be cut off.
즉, 도 5에 도시된 바와 같이 제1기판(111)과 제2기판(115)의 일측 및 타측 부분은 깎아내지 않을 수 있다. That is, as shown in FIG. 5, one side and the other side of the first substrate 111 and the second substrate 115 may not be cut away.
이는 디스플레이 패널을 구동시키기 위한 드라이버 및 각종 회로 소자가 부착된 PCB(Printed Circuit Board)를 포함한 구동 회로부가 기판의 일측 또는 타측에 연결될 수 있기 때문이다.This is because a driver circuit including a printed circuit board (PCB) having a driver for driving the display panel and various circuit elements can be connected to one side or the other side of the substrate.
또한 기판의 일측 및 타측을 깎아내지 않음으로써, 기판의 일측 및 타측 부분이 후속 공정에서 부착될 부재의 가이드 역할을 할 수 있고, 곡면 디스플레이 패널의 구조적 강도를 높이는 역할을 할 수 있다.In addition, by not cutting one side and the other side of the substrate, one side and the other side of the substrate can serve as a guide for a member to be attached in a subsequent process, and can improve the structural strength of the curved display panel.
상기 외측 일부를 깎아내는 단계에서 미리 설정된 두께는 50 내지 150㎛에 속하는 값일 수 있다. The predetermined thickness in the step of cutting out the outer part may be a value belonging to 50 to 150 mu m.
참고로 두께는 곡률 크기에 따라 조절을 해야 하며, 중, 소형일 경우 50㎛ 작거나 150㎛ 보다 클 경우 또는 대형일 경우 200㎛ 보다 작고 400㎛ 보다 크면 휘는 과정에서 부서지거나 잘 휘어지지 않는 문제점이 있다.For the reference, the thickness should be adjusted according to the curvature size. If it is small or medium, if it is smaller than 50 탆, larger than 150 탆 or larger than 200 탆 and larger than 400 탆, it will not bend or bend during bending have.
즉 제1기판(111)과 제2기판(115)의 깎아진 후의 두께는 중, 소형일 경우 50㎛ 내지 150㎛에 속하는 경우, 대형일 경우 200㎛ 내지 400㎛ 속하는 값으로 하는 것은 제1기판 과 제2기판이 부서지지 않으면서 휘어질 수 있도록 하기 위함이다.
That is, when the thickness of the first substrate 111 and the second substrate 115 is in the range of 50 μm to 150 μm when the substrate is small or medium and when the substrate is large, And the second substrate can be bent without breaking.
이어서, 도 6에 도시한 바와 같이, 제1기판(111)과 제2기판(115)의 깎아진 외측면에 제1편광판(polarizer; 117)과 제2편광판(119)을 각각 부착하는 단계를 포함한다(S200).6, a step of attaching a first polarizer 117 and a second polarizer 119 to the outer side surfaces of the first substrate 111 and the second substrate 115, respectively (S200).
이때, 제1편광판(117) 및 제2편광판(119)은 제1기판(111) 및 제2기판(115)이 곡면 형상의 지그 또는 평면인 상태에서 부착될 수도 있다.At this time, the first polarizer 117 and the second polarizer 119 may be attached to the first substrate 111 and the second substrate 115 with a curved jig or a flat surface.
이어서, 도 7에 도시한 바와 같이, 상기 제1기판(111) 및 제2기판(115)에 편광판(117, 119)이 부착되어 이루어진 패널부(110)를 소정의 곡률로 표면이 형성된 지그(Z)에 밀착 고정시킨다(S300).7, the panel unit 110 having the polarizers 117 and 119 attached to the first substrate 111 and the second substrate 115 is attached to a jig having a predetermined curvature Z) (S300).
지그(Z)의 표면은 소정의 곡률을 가지면서 가로 방향이며 상부로 볼록한 형태의 곡면으로 구비된다.The surface of the jig Z is provided with a curved surface having a predetermined curvature and a transverse direction and an upward convex shape.
따라서, 지그(Z)에 상기 패널부(110)가 밀착 고정되면, 상기 패널부(110)도 지그(Z)에 형성된 곡률과 동일한 곡률을 가지면서 가로 방향이며 상부로 볼록한 형태의 곡면으로 형성된다.
Therefore, when the panel unit 110 is closely fixed to the jig Z, the panel unit 110 is also formed in a curved shape having a curvature equal to the curvature formed in the jig Z and a convex shape in the horizontal direction and upward .
이어서, 도 9에 도시한 바와 같이, 상기 지그(Z)에 고정된 패널부(110)의 상면에 중앙부가 관통된 프레임부(150)를 접착시킨다(S400).Next, as shown in FIG. 9, a frame part 150 passing through the center is bonded to the upper surface of the panel part 110 fixed to the jig Z (S400).
상기 프레임부(150)는 금속판 등의 철재류, 알루미늄, 폴리카보네이트 또는 아크릴 수지(PMMA) 등의 플렉시블한 재질로 이루어지며 도 8에 도시한 바와 같이, 사각 형상으로써 테두리를 이루는 지지대부(151)와, 상기 지지대부(151) 사이로 관통구(153)가 형성되어 이루어진다.The frame part 150 is made of a flexible material such as a steel plate such as a metal plate, aluminum, polycarbonate or acrylic resin (PMMA). As shown in FIG. 8, the frame 150 has a support frame 151 And a through hole 153 is formed between the support pieces 151.
미설명 부호 157은 후술하는 체결수단(S)이 체결되는 체결공이다.Reference numeral 157 denotes a fastening hole for fastening the fastening means S to be described later.
상기 프레임부(150)를 지그(Z)에 고정된 패널부(110)의 상면에 접착시킬 때, 상기 프레임부(150)의 일측인 하부 지지대부(151)는 상기 패널부(110)의 일측인 하부보다 길게 연장되도록 접착된다.The lower support portion 151 which is one side of the frame portion 150 is attached to the upper surface of the panel portion 110 fixed to the jig Z, So as to extend longer than the lower part of the lower part.
상기 패널부(110)와 프레임부(150)를 접착시 양면 테잎, 상온 실리콘 또는 UV 경화재 등으로 접착시킬 수 있다.When the panel unit 110 and the frame unit 150 are adhered to each other, they can be adhered to each other using double-faced tape, room temperature silicone, UV curing material, or the like.
상기 패널부(110)에 프레임부(150)가 접착되면, 상기 프레임부(150)도 지그(Z)에 형성된 곡률과 동일한 곡률을 가지면서 가로 방향이며 상부로 볼록한 형태의 곡면으로 형성된다.When the frame part 150 is adhered to the panel part 110, the frame part 150 is formed into a curved surface having a curvature equal to the curvature formed in the jig Z and a transverse direction and convex shape.
이어서, 상기 프레임부(150)가 접착된 패널부(110)를 상기 지그(Z)로부터 분리시키면, 도 10 및 도 11에 도시한 바와 같이 소정의 곡률이 유지되는 곡면 디스플레이 패널(100)이 형성된다.10 and 11, a curved display panel 100 having a predetermined curvature is formed when the panel unit 110 to which the frame unit 150 is bonded is separated from the jig Z. Then, do.
이때, 곡면 디스플레이 패널(100)은 가로 방향이며 오목하게 곡률을 가지는 형태가 된다.
At this time, the curved display panel 100 becomes a shape having a transverse direction and concave curvature.
