Description

액정 적하 장치{Apparatus of dropping liquid crystal}Liquid crystal dropping apparatus {Apparatus of dropping liquid crystal}

도 1은 본 발명의 일 실시예에 따른 액정 적하 장치의 단면도를 나타낸다. 1 is a cross-sectional view of a liquid crystal dropping apparatus according to an embodiment of the present invention.

본 발명은 액정 적하 장치에 관한 것이다. The present invention relates to a liquid crystal dropping device.

액정 표시 패널이 대형화되고 대량 생산됨에 따라 액정을 채우는 방법으로 액정을 기판 상에 적하하는 방법이 있다. 이 방법에서는 박막 트랜지스터 기판 또는 컬러 필터 기판의 가장 자리에 실링 부재를 형성한 후, 액정을 적하하고, 후속으로 두 기판을 서로 대향 합착시킴으로써, 액정이 두 기판 사이에 존재하게 된다. As a liquid crystal display panel becomes large and mass-produced, there is a method of dropping a liquid crystal onto a substrate as a method of filling a liquid crystal. In this method, after the sealing member is formed at the edge of the thin film transistor substrate or the color filter substrate, the liquid crystal is dropped, and the two substrates are subsequently bonded to each other so that the liquid crystal is present between the two substrates.

한편, 액정을 적하함으로써 액정을 채우는 방법은 적하얼룩이라는 문제점을 가진다. 종래의 액정 적하 장치는 액정을 한 덩어리씩 비등방성(aniostropic)으로 적하한다. 그러나 하나의 덩어리 안에 들어있는 액정은 불균일하게 분포할 수 있으며, 액정이 퍼짐에 따라 지점들마다 액정의 밀도가 달라질 수 있다. 이로써 액정의 점도와 같은 물성이 변할 수 있다. 결과적으로 액정 패널 전체로 볼 때 지점마다 액정의 물성이 다를 수 있으며, 이로써 깨끗하고 선명한 화질을 얻기 어렵다. 이를 적하 얼룩이라 한다. On the other hand, a method of filling a liquid crystal by dropping the liquid crystal has a problem of dropping stain. Conventional liquid crystal dropping apparatuses drop liquid crystals anisotropically in bulk. However, the liquid crystal contained in one mass may be unevenly distributed, and as the liquid crystal spreads, the density of the liquid crystal may vary from point to point. As a result, physical properties such as the viscosity of the liquid crystal may change. As a result, the physical properties of the liquid crystal may be different for each point when viewed as a whole of the liquid crystal panel, whereby it is difficult to obtain a clear and clear image quality. This is called dropping stain.

따라서 본 발명의 기술적 과제는 적하 얼룩을 미연에 방지할 수 있는 액정 적하 장치를 제공하는데 있다. Therefore, the technical problem of this invention is providing the liquid crystal dropping apparatus which can prevent dripping unevenness beforehand.

상기 기술적 과제를 달성하기 위한 본 발명에 따른 액정 적하 장치는 초음파를 발생하는 진동판을 포함하는 것을 특징으로 한다. 상기 진동판에 의해 발생된 초음파에 의해 액정은 잘 혼합되어 액정들이 불균일하게 분포하는 지점이 없이 균일하게 섞이게 된다. 또한, 상기 진동판에 의해 발생된 초음파에 의해 액정은 기판 상으로 등방성(isotropic)으로 분사된다. 따라서, 초음파를 발생하는 진동판을 구비하는 본 발명에 따른 액정 적하 장치를 이용하여 액정을 적하할 경우, 패널 전체에서 액정이 고르게 균일하게 분포할 수 있으므로, 깨끗하고 선명한 화질을 기대할 수 있다. Liquid crystal dropping apparatus according to the present invention for achieving the above technical problem is characterized in that it comprises a diaphragm for generating ultrasonic waves. By the ultrasonic waves generated by the diaphragm, the liquid crystals are well mixed so that the liquid crystals are uniformly mixed without a point where the liquid crystals are unevenly distributed. In addition, the liquid crystal is isotropically sprayed onto the substrate by the ultrasonic waves generated by the diaphragm. Therefore, when the liquid crystal is dropped using the liquid crystal dropping apparatus according to the present invention having the diaphragm for generating ultrasonic waves, the liquid crystal can be evenly distributed evenly throughout the panel, so that a clear and clear image quality can be expected.

Therefore, the scope of the present invention should not be construed as limited by the embodiments described below. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Portions denoted by like reference numerals denote like elements throughout the specification.

도 1은 본 발명의 일 실시예에 따른 액정 적하 장치의 단면도를 나타낸다. 1 is a cross-sectional view of a liquid crystal dropping apparatus according to an embodiment of the present invention.

도 1을 참조하면, 액정 적하 장치(100)는 액정(31)이 저장되는 저장부(5)를 포함한다. 상기 저장부(5)의 하단에는 상기 액정(31)을 밖으로 배출하는 노즐부(9)가 위치하고 상기 저장부(5)의 상단에는 액정 공급관(7)이 위치한다. 상기 저장부(5)에는 초음파 발생 장치(20)이 연결되어 있다. 상기 초음파 발생 장치(20)는 초음파(33)를 발생하는 진동판(21)과, 상기 진동판(21)에 연결되며 상기 진동판(22)에 고주파 전압을 인가하여 초음파(33)를 발생시키는 고주파 전압 인가부(23)를 포함한다. 상기 진동판(21)은 상기 저장부(5) 안에 위치한다. 상기 노즐부(9)의 단부는 복수개의 작은 구멍들을 가지며 액정(31)을 분사하는 분사 노즐이 위치할 수 있다. 상기 노즐부(9)의 외측에는 가열기(11)가 위치하여 상기 액정(31)에 열을 가한다. 상기 노즐부(9) 하부에는 기판(3)이 놓이는 기판 수용부(1)가 위치한다. Referring to FIG. 1, the liquid crystal dropping apparatus 100 includes a storage unit 5 in which a liquid crystal 31 is stored. A nozzle unit 9 for discharging the liquid crystal 31 outward is disposed at a lower end of the storage unit 5, and a liquid crystal supply pipe 7 is positioned at an upper end of the storage unit 5. The ultrasonic generator 20 is connected to the storage unit 5. The ultrasonic wave generator 20 is a vibration plate 21 for generating an ultrasonic wave 33, and a high frequency voltage is applied to the vibration plate 21 and generates a ultrasonic wave 33 by applying a high frequency voltage to the vibration plate 22 And a portion 23. The diaphragm 21 is located in the reservoir 5. An end of the nozzle unit 9 may have a plurality of small holes and a spray nozzle for spraying the liquid crystal 31. A heater 11 is positioned outside the nozzle unit 9 to apply heat to the liquid crystal 31. The substrate accommodating part 1 on which the substrate 3 is placed is located under the nozzle part 9.

도 1의 상기 액정 적하 장치(100)에 따르면, 상기 초음파 발생장치(20)에 의해 발생된 초음파(33)가 발생된다. 초음파(33)는 약 2만Hz 이상의 음파로써, 액정(31)에 초음파(33)를 가하면 액정(31)의 수축과 팽창이 교대로 일어나게 되고, 액정(31)들의 분자는 활동성이 증가하여 상기 저장부(6)내에서 상기 액정(31)들이 골고루 섞이게 된다. 또한 초음파(33)에 의해 액정(31) 분자간의 응집력이 파괴되고 수천만 이상의 미세한 공동(cavity)이 발생된다. 이러한 공동이 액정 내부에서 폭발하면서 액정이 증기 형태의 분산 입자로 쪼개지기도 하며, 이러한 에너지에 의해 액정이 사이 노즐부(9)를 통해 등방성(isotropic)으로 분사하게 된다. 상기 가열기(11)에 의해 발생된 열은 상기 액정(31) 분자의 활동성을 보다 더 증가시키는 역할을 한다. 따라서, 상기 액정(31)은 상기 기판(1) 상에 균일하게 도포될 수 있으며, 도포된 액정(31)들은 지점들에 상관없이 균일한 농도나 밀도를 가지게 된다. 따라서, 액정 패널 전체에 있어 지점들에 상관없이 균일한 액정 물성을 가지게 되므로, 적하얼룩 없이 깨끗하고 선명한 화질을 구현할 수 있다. According to the liquid crystal dropping apparatus 100 of FIG. 1, the ultrasonic waves 33 generated by the ultrasonic generator 20 are generated. The ultrasonic waves 33 are sound waves of about 20,000 Hz or more. When the ultrasonic waves 33 are applied to the liquid crystals 31, the contraction and expansion of the liquid crystals 31 alternately occur, and the molecules of the liquid crystals 31 increase in activity. The liquid crystals 31 are evenly mixed in the storage unit 6. In addition, the cohesive force between the molecules of the liquid crystal 31 is destroyed by the ultrasonic waves 33, and tens of millions of fine cavities are generated. As the cavity explodes inside the liquid crystal, the liquid crystal may be split into dispersed particles in the form of vapor, and the liquid crystal isotropically injected through the nozzle part 9 by the energy. The heat generated by the heater 11 serves to further increase the activity of the molecules of the liquid crystal 31. Accordingly, the liquid crystal 31 may be uniformly coated on the substrate 1, and the liquid crystals 31 may have a uniform concentration or density regardless of points. Thus, since the liquid crystal panel has uniform liquid crystal properties regardless of the points, it is possible to realize a clear and clear image without dropping.

비록 상기 실시예에서, 상기 초음파 발생 장치(20)가 상기 저장부(5)에 장착되고, 상기 가열기(11)가 상기 노즐부(9)를 감싸도록 장착되었으나, 상기 초음파 발생 장치(20)와 상기 가열기(11)의 설치 위치는 필요에 따라 변경될 수 있음은 당업자에게 자명한 것이다. Although in the above embodiment, the ultrasonic wave generator 20 is mounted to the storage portion 5 and the heater 11 is mounted to surround the nozzle portion 9, the ultrasonic wave generator 20 It will be apparent to those skilled in the art that the installation position of the heater 11 can be changed as necessary.

따라서, 본 발명에 따른 액정 적하 장치는 초음파를 발생하는 진동판을 포함하여, 패널 전체에서 액정이 균일하게 도포될 수 있으므로, 깨끗하고 선명한 화질 을 구현할 수 있다. Therefore, the liquid crystal dropping apparatus according to the present invention may include a diaphragm for generating ultrasonic waves, and thus the liquid crystal may be uniformly applied to the entire panel, thereby realizing clean and clear image quality.
