본 고안은 액정표시패널에 액정을 주입하기 위한 액정주입장치에 관한 것이다.The present invention relates to a liquid crystal injection device for injecting liquid crystal into the liquid crystal display panel.
통상적으로 액정표시패널은 제l도에 도시된 바와같이, 상·하부기판(2, 3)과, 이 상·하부기판(2, 3)을 소정 간격이 격되게 결합시키며 상·하부기판(2, 3)과 함께 소정의 공간부(5)를 형성하는 실링부재(4)를 구비하고 있다. 상기 공간부(5)에는, 이 공간부(5)와 외부를 연통시키는 주입구(6)를 통해, 액정이 주입되게 된다.In general, as shown in FIG. 1, the liquid crystal display panel combines the upper and lower substrates 2 and 3 with the upper and lower substrates 2 and 3 at predetermined intervals, and the upper and lower substrates 2 are separated from each other. And 3) together with a sealing member 4 forming a predetermined space portion 5. The liquid crystal is injected into the space portion 5 through the injection hole 6 which communicates the space portion 5 and the outside.
한편, 상기 공간부(5)에 액정을 주입하는 과정을 제2도 및 제3도를 참조하면서 살펴보면 다음과 같다.Meanwhile, a process of injecting liquid crystal into the space part 5 will be described with reference to FIGS. 2 and 3.
먼저 액정(9)을 수용한 용기(8)가 들어 있는 챔버(7)의 내부로 복수개의 액정표시패널(1)을 투입한다. 이 때, 제2도에 도시된 바와 같이, 주입구(6)가 액정(9)의 상방으로 소성거리 이격되게 위치하도록 액정표시패널(1)을 위치시킨다. 그리고, 챔버(7)의 일측에 마련된 공기유출입구(7a)를 통해 챕버(7) 내부의 공기 및 액정표시패널(1)의 공간부(5) 내의 공기를 외부로 배출시켜 챔버(7) 및 액정표시패널(1)의 공간부(5)가 진공상태를 유지하도록 한다.First, a plurality of liquid crystal display panels 1 are introduced into the chamber 7 in which the container 8 containing the liquid crystal 9 is contained. At this time, as shown in FIG. 2, the liquid crystal display panel 1 is positioned such that the injection hole 6 is positioned above the liquid crystal 9 so as to be spaced apart from the firing distance. Then, the air inside the chapter 7 and the air in the space 5 of the liquid crystal display panel 1 are discharged to the outside through the air outlet 7a provided at one side of the chamber 7. The space 5 of the liquid crystal display panel 1 is maintained in a vacuum state.
이러한 상태에서 액정표시패널(1)을 하강시켜 제3도에 도시된 바와 같이, 주입구(6)가 액정(9)에 잠기도록 한 후, 공기유출입구(7a)를 통해 진공분위기의 챔버(7) 내부로 질소 가스 등과 같은 소정의 기체를 유입시킨다. 그러면 액정표시패널(1) 내부의 공간부(5)가 진공상태를 유지하는 상태에서, 유입된 기체에 의해 액정(9)에 압력이 작용하게 되며, 이 압력에 의해 액정(9)이 액정표시패널(1)의 주입구(6)를 통해 진공상태의 공간부(5)로 주입되게 된다.In this state, the liquid crystal display panel 1 is lowered so that the injection hole 6 is immersed in the liquid crystal 9, as shown in FIG. 3, and then the chamber 7 of the vacuum atmosphere through the air outlet 7a. ) A predetermined gas such as nitrogen gas is introduced into the inside. Then, in the state where the space 5 inside the liquid crystal display panel 1 maintains the vacuum state, pressure is applied to the liquid crystal 9 by the introduced gas, and the liquid crystal 9 causes the liquid crystal display by the pressure. It is injected into the space part 5 in a vacuum state through the injection hole 6 of the panel 1.
그러나,이러한 방식에 의해 액정(1)을주입하게 되면, 액정표시패널(1)에 있어서, 액정(9)에 잠겨 있던 부위에 액정이 뭍어나게 되므로 액정의 손실이 많아질 뿐만 아니라, 액정표시패널에 부착된 액정을 제거한느데도 많은 시간과 노력을 필요로 하는 등의 문제가 있었다.However, when the liquid crystal 1 is injected in this manner, since the liquid crystal is drawn out at the portion immersed in the liquid crystal 9 in the liquid crystal display panel 1, not only the loss of the liquid crystal increases but also the liquid crystal display panel. There was a problem such as requiring a lot of time and effort to remove the liquid crystal attached to the.
본 고안은 이러한 문제점을 해결하기 의하여 안출된 것으로서, 액정표시패널의 내부에 액정을 주입함에 있어서, 다량의 액정이 액정표시패널의 외부에 부착됨에 의해 발생하는 액정의 손실을 억제할 수 있도록 된 액정주입장치를 제공함에 목적이 있다.The present invention has been made to solve this problem, the liquid crystal is to be able to suppress the loss of the liquid crystal caused by a large amount of liquid crystal attached to the outside of the liquid crystal display panel when injecting the liquid crystal inside the liquid crystal display panel It is an object to provide an injection device.
이러한 목적을 달성하기 의하여 본 고안은 그 내부로 액정이 주입될 수 있도록 주입구를 갖는 액정표시패널에 액정을 주입하기 위한 액정주입장치에 있어서, 그 내부에 액정이 충진되며 상기 액정표시패널의 주입구측과 탄력접촉하는 액정충진부재와, 일측은 상기 액정에 잠기며 타측에는 상기 액정충진부재가 고정되고 상기 액정이 상기 액정충진부재에 충진될 수 있도록 유동하는 액정유동경로를 갖춘 지지부재를 구비하여 된 점에 특징이 있다.In order to achieve the above object, the present invention provides a liquid crystal injection device for injecting liquid crystal into a liquid crystal display panel having an injection hole so that liquid crystal can be injected into the liquid crystal. And a support member having a liquid crystal filling member in elastic contact with the liquid crystal, and having one side immersed in the liquid crystal and the other side fixed with the liquid crystal filling member and flowing to allow the liquid crystal to be filled in the liquid crystal filling member. There is a characteristic in point.
이하 본 고안에 따른 바람직한 일 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제4도에는 본 고안에 따른 액정주입장치의 일예가 도시되어 있다.4 shows an example of a liquid crystal injection apparatus according to the present invention.
도면을 참조하면, 액정주입장치(10)에는 지지부재(20)와 액정충진 부재(30)가 마련되어 있는데, 지지부재(20)의 바닥부는 액정에 잠기게되며 상부에는 상기 액정충진부재(30)가 고정된다. 그리고 지지부재(20)의 양측면에는 액정이 유동하는 액정유동경로로서 복수개의 패널(21)이 형성되이 있다. 그리고, 액정충진부재(30)는 액정표시패널(l)의 주입구(6)측과 탄력 접촉하게 되며, 내부에는 지지부재(20)에 형성된 복수개의 채널(21)를 따라 모세관현상에 의해 상승하는 액정이 충진되게 된다. 한편, 액정충진부재(30)는 통상적으로 스폰지라 일컬어지는 발포수지를 사용함이 바람직하다.Referring to the drawings, the liquid crystal injection device 10 is provided with a support member 20 and a liquid crystal filling member 30, the bottom of the support member 20 is immersed in the liquid crystal and the upper liquid crystal filling member 30 Is fixed. A plurality of panels 21 are formed on both sides of the support member 20 as liquid crystal flow paths through which liquid crystal flows. In addition, the liquid crystal filling member 30 is in elastic contact with the injection hole 6 side of the liquid crystal display panel 1, and therein, the liquid crystal filling member 30 rises due to a capillary phenomenon along a plurality of channels 21 formed in the support member 20. The liquid crystal is filled. On the other hand, the liquid crystal filling member 30 is preferably used a foamed resin commonly referred to as a sponge.
이러한 구조를 갖는 액정주입장치(10)를 사용하여 액정표시패널(1)에 액정을 주입하는 과정을 제5도 및 제6도를 참조하면서 살펴보면 다음과 같다.The process of injecting liquid crystal into the liquid crystal display panel 1 using the liquid crystal injection apparatus 10 having such a structure will be described below with reference to FIGS. 5 and 6.
먼저, 그 일측에 공기유출입경로(7a)가 구비된 챔버(7) 내부에 액정(9)이 수용된 용기(8)를 넣어 두고, 그 용기(8)에 수용된 액정(9)에 액정주입장치(10)의 지지부재(20) 일부가 잠기게 한다. 그러면 지지부재(20)의 채널(2l)을 통해, 모세관현상에 의해, 액정(9)이 상승하여 액정충진부재(30)에 충진되게 된다. 그리고, 챔버(7)에 복수개의 액정표시패널(l)을 투입하는데, 제5도에 도시된 바와 같이, 액정표시패널(1)에 형성된 주입구(6)가 액정주입장치(10)의 액정충진부재(30)의 상방으로 소정거리 이격되게 위치하도록 액정표시패널(1)을 위치시킨다. 그리고, 챔버(7)에 마련된 공기유출입구(7a)를 통해 챔버(7) 내부의 공기 및 액정표시패널(1)의 공간부(6) 내의 공기를 외부로 배출시켜 챔버(7) 및 액정표시패널(1) 내부의 공간부(6)가 진공상태를 유지하도록 한다.First, a container 8 containing a liquid crystal 9 is placed in a chamber 7 provided with an air outlet path 7a on one side thereof, and a liquid crystal injection device is placed in the liquid crystal 9 contained in the container 8. Part 10 of the support member 20 is locked. Then, the liquid crystal 9 rises and fills the liquid crystal filling member 30 through capillary action through the channel 2l of the supporting member 20. In addition, a plurality of liquid crystal display panels 1 are introduced into the chamber 7, and as shown in FIG. 5, the injection holes 6 formed in the liquid crystal display panel 1 are filled with liquid crystals in the liquid crystal injection device 10. The liquid crystal display panel 1 is positioned to be spaced apart from the member 30 by a predetermined distance. Then, the air in the chamber 7 and the air in the space 6 of the liquid crystal display panel 1 are discharged to the outside through the air outlet 7a provided in the chamber 7. The space 6 inside the panel 1 is maintained in a vacuum state.
그리고 액정표시패널(1)을 하강시키게 되면, 제6도에 도시된 바와 같이, 액정표시패널(1)이 액정충진부재(30)를 압압하며 지지부재(20)의 상부에 접촉하게 되고, 압압된 액정충진부재(30)는 액정표시패널(1)의 주입구(6)측에 탄력적으로 접촉하게 된다. 이러한 상태에서, 공기유출입구(7a)를 통해 진공분위기의 챔버(7) 내부로 질소 가스 등과 같은 소성의 기체를 유입시킨다. 그러면 액정표시패널(1) 내부의 공간부(5)가 진공상태를 유지하는 상태에서, 액정충진부재(30)에 충진되어 있는 액정에 압력이 작용하게 되며, 이 압력에 의해 상기 액정이 액정표시패널(1)의 주입구(6)를 통해 진공상태의 공간부(5)로 주입되게 된다.When the liquid crystal display panel 1 is lowered, as shown in FIG. 6, the liquid crystal display panel 1 presses the liquid crystal filling member 30 and contacts the upper portion of the support member 20. The liquid crystal filling member 30 is in elastic contact with the injection hole 6 side of the liquid crystal display panel 1. In this state, a gas of firing, such as nitrogen gas, is introduced into the chamber 7 of the vacuum atmosphere through the air outlet 7a. Then, pressure is applied to the liquid crystal filled in the liquid crystal filling member 30 while the space 5 inside the liquid crystal display panel 1 maintains a vacuum state. It is injected into the space part 5 in a vacuum state through the injection hole 6 of the panel 1.
이러한 과정에서, 액정은 액정충진부재를 통해 액정표시패널의 주입구측 일부에만 접촉하게 되므로, 주입작업이 완료된 후 액정이 액정표시패널의 넓은 범위에 걸쳐 뭍어 나는 것이 억제되게 된다.In this process, since the liquid crystal contacts only a portion of the injection port side of the liquid crystal display panel through the liquid crystal filling member, the liquid crystal is suppressed from floating over a wide range of the liquid crystal display panel after the injection operation is completed.
따라서 액정의 과대한 손실을 억제할 수 있다.Therefore, excessive loss of liquid crystal can be suppressed.
한편, 제7도에는 본 고안에 따른 따른 유형의 액정주입장치가, 일부 절제된 개략적 사시도로서 도시되어 있는데, 이는 지기부재(60)의 중앙부를 상하로 관통하는 복수개의 관통공(61)을 액정유동경로로서 채용한 것이다. 이러한 구조를 갖는 액정주입장치(50)의 작용이나 사용방법 등은 상술한 실시예에서 설명한 바와 동일하나, 지지부재(60)의 상하를 관통하는 관통공(61)을 액정이 액정충진부재(70)의 내부에 충전될 수 있도록 유동하는 액정유동경로로서 채용하고 있으므로, 액정유동경로의 길이가 최소화되어, 복수개의 액정표시패널에 액정을 주입하는 작업을 연속적으로 행한 후, 보관 등의 이유로 액정주입장치를 액정으로부터 건져 올리게되는 경우에, 그 액정주입장치에 뭍어나는 액정(보다 구체적으로는 지지부재에 형성된 액정유동경로에 뭍어나는 액정)의 손실을 효과적으로 감소시킬 수 있는 장점이 있다.Meanwhile, FIG. 7 shows a liquid crystal injection device of the type according to the present invention as a partially cut-out schematic perspective view, which includes a plurality of through-holes 61 penetrating up and down the central portion of the support member 60. It is adopted as a route. The operation and use method of the liquid crystal injection device 50 having such a structure is the same as described in the above-described embodiment, but the liquid crystal filling member 70 has a through hole 61 penetrating the upper and lower sides of the support member 60. Since it is adopted as a liquid crystal flow path that flows to fill the inside of the panel), the length of the liquid crystal flow path is minimized, and the operation of continuously injecting the liquid crystal into the plurality of liquid crystal display panels is performed. When the device is lifted up from the liquid crystal, there is an advantage that the loss of the liquid crystal (more specifically, the liquid crystal flowing out of the liquid crystal flow path formed in the support member) out of the liquid crystal injection device can be effectively reduced.
또한, 상술한 실시예들에서는 지지부재와 액정함침부재가 별도로 마련되어 상호 고성결합되는 경우에 대하여 살펴보았으나, 경우에 따라서는 상기 지지부재가 상기 액정함침부재와 일체적으로 형성될 수도 있을 것이다.In addition, in the above-described embodiments, a case in which the support member and the liquid crystal impregnating member are separately provided and then coupled to each other is described. However, in some cases, the support member may be integrally formed with the liquid crystal impregnating member.
이상에서 살펴본 바와 같이 본 고안 액정주입장치를 사용하게 되면, 액정이 액정표시패널 주입구측 일부에만 접촉하는 액정충진부재를 통해 주입되도록 되어 있으므로, 액정표시패널의 외부에 다량의 액정이 부착됨으로 인한 액정의 손실을 억제할 수 있을 뿐만 아니라, 액정주입작업 후 액정표시패널에 뭍은 액정을 제거하는데 소요되는 작업시간을 극소화하여 액정표새패널의 원가절감 및 생산성향상에 크게 이바지하게 된다.As described above, when the liquid crystal injection device of the present invention is used, the liquid crystal is injected through the liquid crystal filling member which contacts only a part of the liquid crystal display panel injection hole, so that a large amount of liquid crystal is attached to the outside of the liquid crystal display panel. In addition to suppressing the loss of the liquid crystal, the time required for removing the liquid crystal deposited on the liquid crystal display panel after the liquid crystal injection operation is minimized, thereby greatly reducing the cost and productivity of the liquid crystal display panel.
