Field of the Invention The present invention relates to a smart window system. The present invention relates to a smart window system that can selectively and variously control a skylight area, and to increase the ease of use by allowing easy control of the skylight area and remote control. .
일반적으로, 스마트 윈도우(smart window)는 태양광의 투과율을 자유롭게 조절할 수 있도록 제작된 윈도우를 말하는 것으로, 전자 커튼, 투과도 가변 유리, 조광 유리 등으로도 불린다.Generally, a smart window refers to a window manufactured to freely control the transmittance of sunlight, and is also referred to as an electronic curtain, a variable transmittance glass, a dimming glass, or the like.
종래에는 유리를 통해 실내로 유입되는 태양광의 투과율을 조절하기 위해, 유리 조성에 착색 산화물을 첨가하여 착색 유리를 만들거나, 유리 표면에 특정 투과율을 가지는 필름지를 부착하는 방식 등이 사용되어 왔다. 그러나 이러한 종래 방법들은 태양광에 대한 능동적인 조절 기능이 없고, 단지 일정한 광 파장 영역에 한해 선택적으로 차폐 또는 투과를 수행하는 수동적인 방식이었다.Conventionally, in order to control the transmittance of sunlight flowing into the room through glass, a method of making colored glass by adding colored oxide to the glass composition, or attaching film paper having a specific transmittance to the glass surface has been used. However, these conventional methods do not have an active control function for sunlight and are a passive method of selectively shielding or transmitting only in a certain light wavelength region.
스마트 윈도우는 이러한 종래의 문제점을 해결하기 위한 것으로, 광투과율과 색상 등을 인위적으로 조절할 수 있는 능동형 제품으로, 현재 유리 분야의 차세대 제품 중 하나로 인식되고 있다. The smart window is to solve such a conventional problem, and is an active product that can artificially adjust light transmittance and color, and is currently recognized as one of the next generation products in the glass field.
이와 같은 스마트 윈도우는 단순하게 모든 영역의 차폐 혹은 개방 형식으로만 사용하여 왔으며, 이로 인하여 추가적으로 브라인드를 설치해야만 하였다. 따라서 종래의 스마트 윈도우의 경우, 전원의 인가 여부에 따라 윈도우 전체의 광투과율이 변하도록 구성되어 있으며, 일부영역 만을 투명 또는 불투명하게 하는 것이 어려웠다. 그러나, 이러한 종래의 제품을 이용할 경우, 창전체를 변색시켜야 하기 때문에, 응답속도가 느리고, 사용효율이 떨어지는 문제점이 있었다.Such smart windows have been used simply as a shield or open type in all areas, and thus additionally have to install a blind. Therefore, in the conventional smart window, the light transmittance of the entire window is changed depending on whether power is applied, and it is difficult to make only a partial region transparent or opaque. However, when using such a conventional product, since the whole window must be discolored, there is a problem that the response speed is slow and the use efficiency is lowered.
이를 개선하기 위하여, 한국공개특허 제10-2011-0030410호의 스마트 윈도우 장치 및 그 제조 방법이 제시된 바 있는데, 이러한 종래 기술은 투명한 고분자 기재로 이루어진 상판 및 하판, 상기 상판의 일면에 형성되며, 투명하고 도전성이 있는 상부 전극층, 상기 하판의 일면에 형성되며, 투명하고 도전성이 있는 하부 전극층 및 상기 상부 전극층 및 하부 전극층 사이에 개재되는 폴리머 분산 액정층으로 이루어지는 폴리머 분산 액정(PDLC) 패널; 상기 폴리머 분산 액정(PDLC) 패널의 일면에 부착되어, 상기 폴리머 분산 액정 패널을 소망하는 면에 탈, 부착할 수 있도록 하는 점착 시트; 및 상기 상부 전극층 및 하부 전극층에 전기적으로 연결되어 상기 상부 전극층 및 하부 전극층의 구동을 제어하는 컨트롤러를 포함하며, 상기 상부 전극층 및 하부 전극층 중 적어도 하나는 다수의 분할 전극으로 이루어진다.In order to improve this, the smart window device and the manufacturing method of the Korean Patent Publication No. 10-2011-0030410 has been proposed, the prior art is formed on one side of the upper plate and the lower plate, the upper plate made of a transparent polymer substrate, A polymer dispersed liquid crystal (PDLC) panel including a conductive upper electrode layer, a lower conductive layer formed on one surface of the lower plate, and a polymer dispersed liquid crystal layer interposed between the upper electrode layer and the lower electrode layer; An adhesive sheet attached to one surface of the polymer dispersed liquid crystal (PDLC) panel to attach and detach the polymer dispersed liquid crystal panel to a desired surface; And a controller electrically connected to the upper electrode layer and the lower electrode layer to control driving of the upper electrode layer and the lower electrode layer, wherein at least one of the upper electrode layer and the lower electrode layer includes a plurality of split electrodes.

셋째, 원격지에서 채광 영역의 조절이 가능하지 않아, 필요에 따른 원격 조절이 불가능하다는 문제점을 가지고 있었다.Third, there is a problem that can not be adjusted remotely according to the need, because it is not possible to control the mining area in the remote.

도 1 내지 도 3을 참조하면, 본 발명의 제 1 실시례에 따른 스마트 윈도우 시스템(10)은 폴리머 분산 액정 패널(Polymer Dispersed Liquid Crystal panel, PDLC panel)(100), 점착 시트(200), 수신부(300), 그리고 제 1 및 제 2 콘트롤러(400,500)를 포함할 수 있다.1 to 3, the smart window system 10 according to the first embodiment of the present invention is a polymer dispersed liquid crystal panel (PDLC panel) 100, the adhesive sheet 200, the receiver 300, and first and second controllers 400 and 500.
폴리머 분산 액정 패널(100)은 폴리머 분산 액정층(110)과, 폴리머 분산 액정층(110)의 양측면에 각각 마련됨과 아울러 각각이 다수의 분할전극(121,131)으로 이루어지는 투명 도전성의 제 1 및 제 2 전극층(120,130)과, 제 1 및 제 2 전극층(120,130) 각각의 외측면에 각각 마련됨과 아울러 투명한 고분자 기재로 이루어지는 제 1 및 제 2 판(140,150)으로 이루어진다. The polymer dispersed liquid crystal panel 100 is provided on both sides of the polymer dispersed liquid crystal layer 110 and the polymer dispersed liquid crystal layer 110, and each of the first and second transparent conductive layers consisting of a plurality of split electrodes 121 and 131. The electrode layers 120 and 130 and the outer and outer surfaces of the first and second electrode layers 120 and 130, respectively, are provided, and the first and second plates 140 and 150 are made of a transparent polymer substrate.
폴리머 분산 액정층(110)은 액정 입자(111)와 감광성 폴리머(112) 용액을 포함하여 이루어질 수 있다. 폴리머 분산 액정층(110)에 자외선이 조사되면, 감광성 폴리머(112)가 경화되면서, 폴리머 분산 액정층(110) 내부에 다수의 기공이 발생하고, 이러한 기공 내에 액정 입자(111)가 포함된 형태가 된다. 전압이 인가되지 않은 상태에서는 액정을 둘러싼 감광성 폴리머(112)와 액정 입자(111)들이 랜덤하게 배열되어 있기 때문에, 빛이 투과되지 못하고, 산란되어 불투명한 상태를 이루게 된다. 그러나 전압을 인가하면 액정 입자(111)들이 분극하여 일정한 규칙성을 가지고 배열되고, 감광성 폴리머(112) 분자들도 그 투과축을 따라 배열된다. 이와 같이 액정 입자(111)와 감광성 폴리머(112) 분자들이 일정한 배열을 가질 경우, 폴리머 분산 액정 패널(100)에 입사한 빛이 투과되게 되며, 그 결과 투명한 상태가 된다. 따라서, 제 1 및 제 2 전극층(120,130)에 전압을 인가하여, 전계를 형성함으로써 채광 영역, 즉 빛의 투과도를 조절할 수 있다.The polymer dispersed liquid crystal layer 110 may include a liquid crystal particle 111 and a photosensitive polymer 112 solution. When ultraviolet rays are irradiated onto the polymer dispersed liquid crystal layer 110, the photosensitive polymer 112 is cured, and a plurality of pores are generated in the polymer dispersed liquid crystal layer 110, and the liquid crystal particles 111 are included in the pores. Becomes In the state where no voltage is applied, since the photosensitive polymer 112 and the liquid crystal particles 111 surrounding the liquid crystal are randomly arranged, light may not be transmitted and scattered to form an opaque state. However, when a voltage is applied, the liquid crystal particles 111 are polarized and arranged with a constant regularity, and the molecules of the photosensitive polymer 112 are also arranged along the transmission axis. As such, when the liquid crystal particles 111 and the photosensitive polymer 112 molecules have a constant arrangement, the light incident on the polymer dispersed liquid crystal panel 100 is transmitted, resulting in a transparent state. Therefore, by applying a voltage to the first and second electrode layers 120 and 130 to form an electric field, the light transmission area, that is, the transmittance of light can be adjusted.
액정 입자(111)는 예컨대, 시아노-바이페닐(Cyano-Biphenyl)계열 단일 액정들이 혼합된 혼합액정, 바이페닐 메소겐(Biphenyl Mesogen)에 플루오르가 치환된 단일 액정들이 혼합된 혼합액정, 터셔리 페닐(Ter-Phenyl) 및 바이 페닐(Biphenyl)계열 단일액정들이 혼합된 혼합액정 등이 사용될 수 있다. 또한 감광성 폴리머(112)는 예컨대, 폴리비닐알콜계, 에폭시계 또는 우레탄 아크릴레이트계의 폴리머 매트릭스가 사용될 수 있다. The liquid crystal particles 111 may be, for example, a mixed liquid crystal in which cyano-Biphenyl-based single liquid crystals are mixed, a mixed liquid crystal in which fluorine is substituted in biphenyl mesogen, and a tertiary mixture. Mixed liquid crystals in which phenyl (Ter-Phenyl) and biphenyl series single liquid crystals are mixed may be used. In addition, the photosensitive polymer 112 may be a polymer matrix of, for example, polyvinyl alcohol, epoxy, or urethane acrylate.
폴리머 분산 액정층(110)에는 계면 활성제가 포함될 수 있는데, 계면 활성제로는 예컨대 스테아릴 메타크릴레이트(Stearly Methacrylate) 등이 사용될 수 있다. 이러한 계면 활성제가 폴리머 분산 액정층(110)에 첨가될 경우, 전압 인가시 감광성 폴리머(112)와 액정 입자(111)의 배향 변경이 보다 쉽게 이루어질 수 있기 때문에, 구동 전압을 낮출 수 있다.The polymer dispersed liquid crystal layer 110 may include a surfactant, for example, stearyl methacrylate (Stearly Methacrylate) may be used as the surfactant. When such a surfactant is added to the polymer dispersed liquid crystal layer 110, since the orientation change of the photosensitive polymer 112 and the liquid crystal particles 111 may be more easily performed when voltage is applied, the driving voltage may be lowered.
제 1 및 제 2 판(140,150)은 하나의 예시로서, 상판과 하판을 각각 이룰 수 있으며, 투광성이 있는 고분자 기재로 이루어지는데, 여기서 고분자 기재는 폴리에스테르(Polyester, PET)필름, 폴리카보네이트(polycarbonate, PC)필름, 폴리메틸메타크릴레이트(Polymethylmethacrylate,PMMA)필름, 폴리에틸렌나프탈레이트(Polyethylene Naphthalate, PEN)필름과 같은 투명한 재질의 고분자 필름이 사용될 수 있으며, 일례로 폴리에스테르필름이 사용될 수 있다. 이와 같이, 폴리머 분산 액정 패널(100)은 기존 스마트 윈도우 장치가 사용하는 유리기판을 사용하지 않게 됨으로써 복잡한 유리접합공정을 거치지 않아도 된다.As an example, the first and second plates 140 and 150 may form a top plate and a bottom plate, respectively, and are made of a light-transmitting polymer substrate, wherein the polymer substrate is a polyester (PET) film or a polycarbonate. , PC) film, polymethylmethacrylate (PMMA) film, a polymer film of a transparent material such as polyethylene naphthalate (PEN) film may be used, for example, a polyester film may be used. As such, the polymer dispersed liquid crystal panel 100 does not use the glass substrate used by the existing smart window device, and thus does not have to undergo a complicated glass bonding process.
제 1 판(140)은 일례로 표면에 노출되는 면이거나, 노출되는 외측을 향하는 면일 수 있는데, 표면의 경도가 3~7H일 수 있다. 따라서 제 1 판(140)은 이러한 표면의 경도로 인해 쉽게 손상되지 않도록 함으로써, 유리기판 없이도 단독으로 사용할 수 있도록 한다. 이를 위해 제 1 판(140)은 경도가 높은 재질로 제조된 플라스틱필름을 사용하거나, 기존의 플라스틱필름 상에 하드 코팅층을 형성할 수 이다. 또한 제 1 및 제 2 판(140,150)은 서로 대향되는 각각의 일면에 제 1 및 제 2 전극층(120,130)이 일례로 코팅에 의해 마련될 수 있다. The first plate 140 may be, for example, a surface exposed to the surface, or a surface facing outwardly exposed, the hardness of the surface may be 3 ~ 7H. Therefore, the first plate 140 is not easily damaged due to the hardness of the surface, so that it can be used alone without a glass substrate. To this end, the first plate 140 may use a plastic film made of a material having high hardness, or may form a hard coating layer on an existing plastic film. In addition, the first and second plates 140 and 150 may be provided by coating the first and second electrode layers 120 and 130 on one surface of the first and second plates 140 and 150 that face each other.
제 1 및 제 2 전극층(120,130)은 폴리머 분산 액정층(110)과 접하도록 형성되어 폴리머 분산 액정층(110)에 전압을 인가하는 기능을 수행한다. 또한 제 1 및 제 2 전극층(120,130)은 예컨대 제 1 및 제 2 판(140,150)을 이루는 고분자 기재 상에 ITO, IZO, ATO, 그래핀(graphene), PEDOT(Poly 3,4-EthyleneDiOxyThiophene), CNT(Carbon Nano Tube, 탄소나노튜브) 등과 같은 투명 전극 재료를 증착 또는 코팅함으로써 형성될 수 있다. The first and second electrode layers 120 and 130 are formed to contact the polymer dispersed liquid crystal layer 110 to perform a function of applying a voltage to the polymer dispersed liquid crystal layer 110. In addition, the first and second electrode layers 120 and 130 may be formed of, for example, ITO, IZO, ATO, graphene, PEDOT (Poly 3,4-EthyleneDiOxyThiophene), or CNT on the polymer substrate constituting the first and second plates 140 and 150. It may be formed by depositing or coating a transparent electrode material such as (Carbon Nano Tube, carbon nanotube).
제 1 및 제 2 전극층(120,130) 각각은 다수의 분할전극(121,131)으로 이루어지는데, 제 1 전극층(120)의 분할전극(121) 각각은 제 1 콘트롤러(500)에 의해, 제 2 전극층(130)의 분할전극(131) 각각은 제 2 콘트롤러(600)에 의해 독립적으로 구동함으로써, 하나의 스마트 윈도우 시스템(10) 내에서 빛이 투과되는 영역인 투명 영역과 빛이 투과되지 않는 영역인 불투명 영역을 선택적으로 구현할 수 있을 뿐만 아니라, 제 1 및 제 2 콘트롤러(500,600)의 듀얼 제어에 의해 제 1 및 제 2 전극층(120,130)이 서로 독립적으로 개별 제어됨으로써, 스마트 윈도우 시스템(10) 내에서 광투과 영역의 제어를 섬세하면서도 다양하게 수행할 수 있도록 하여, 사용자의 만족도를 높일 수 있다.Each of the first and second electrode layers 120 and 130 includes a plurality of split electrodes 121 and 131. Each of the split electrodes 121 of the first electrode layer 120 is formed by the first controller 500 and the second electrode layer 130. Each of the split electrodes 131 is independently driven by the second controller 600, so that the transparent region and the opaque region in which the light is transmitted and the region in which the light is not transmitted in the smart window system 10 are independently driven. In addition, the first and second electrode layers 120 and 130 are individually controlled independently of each other by dual control of the first and second controllers 500 and 600, thereby allowing light transmission in the smart window system 10. The user's satisfaction can be improved by controlling the area in a delicate and diverse manner.
제 1 및 제 2 전극층(120,130) 각각은 투명 전극층에 대한 레이저를 이용한 식각 공정에 의해, 다수의 분할전극(121,131)을 형성할 수 있다. 또한 제 1 및 제 2 전극층(120,130) 중 어느 하나 또는 모두는 분할전극(121,131)이 본 실시례에서처럼 직사각형으로 이루어져서 나란하도록 다수로 배열되는 스트라이프 형태로 분할 형성되거나, 다른 예로서 사각형이 전후 및 좌우 다수로 배열되는 격자 형태로 분할 형성될 수 있으며, 이 밖에도 다양한 패턴이나 구조로 분할 형성될 수 있으며, 필요에 따라 문자나 그래픽을 구현할 수 있는 패턴으로 형성될 수 있다.Each of the first and second electrode layers 120 and 130 may form a plurality of split electrodes 121 and 131 by an etching process using a laser to the transparent electrode layer.
