이 고안은 고분자 분산 액정필름을 이용하여 빛이 현란하게 반사됨이 없고 눈부심이 최소화되도록 한 고분자 분산 액정필름을 이용한 방현거울에 관한 것이다.The present invention relates to an antiglare mirror using a polymer dispersed liquid crystal film, which uses a polymer dispersed liquid crystal film so that light is not reflected remarkably and the glare is minimized.
일반적으로, 액정 표시소자를 거울로 이용하는 기술은 거의 제시되어 있지 않은바, 이는 액정표시소자의 광투과율이 그다지 크기 않으며 일예로 게스트 호스트방식에 의해 염료와 액저을 사용한 액정표시장치의 경우에는 빛반사율이 60% 이하로써 거울로 사용하기가 곤란하였다.In general, a technology using a liquid crystal display device as a mirror has not been suggested. This is because the light transmittance of the liquid crystal display device is not very large. For example, in the case of a liquid crystal display device using a dye and a liquid crystal by a guest host method, light reflectance is used. This was less than 60%, making it difficult to use as a mirror.
이 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 이 고안의 목적은 폴리머 액정필름을 이용하여 방현거울을 형성하고 상기 폴리머 액정필름에 전원이 인가되도록 진공증착으로 투명전극을 형성함으로써 폴리머 액정필름에 전원이 인가되면 빛의 투과율이 변화됨에 따라 반사되어 오는 빛의 현란함이 없도록 한 고분자 분산 액정필름을 이용한 방현거울을 제공하는데 있다.The object of the present invention is to solve the conventional problems as described above, and an object of the present invention is to form an antiglare mirror using a polymer liquid crystal film and to form a transparent electrode by vacuum deposition so that power is applied to the polymer liquid crystal film. When the power is applied to the film is to provide an antiglare mirror using a polymer dispersed liquid crystal film so that there is no glare of the reflected light as the light transmittance is changed.
상기와 같은 목적을 달성하기 위한 이 고안에 따른 고분자 분산 액정필름을 이용한 방현거울의 특징은, 하부필름에 알루미늄을 증착시켜서 알루미늄 증착증을 형성하고 상기 알루미늄 증착층상에 폴리머 액정측과 상부기판이 형성되어 있는 점에 있다.A feature of the antiglare mirror using the polymer dispersed liquid crystal film according to the present invention for achieving the above object is to form aluminum deposition by depositing aluminum on the lower film, and the polymer liquid crystal side and the upper substrate are formed on the aluminum deposition layer. It is in a point.
이하, 이 고안에 따른 고분자 분산 액정필름을 이용한 방현거울의 바람직한 하나의 실시예에 대하여 첨부도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of an antiglare mirror using a polymer dispersed liquid crystal film according to the present invention will be described in detail with reference to the accompanying drawings.
제 1 도는 이 고안에 따른 고분자 분산 액정필름을 이용한 방현거울을 설명하기 위한 도면이다.1 is a view for explaining an antiglare mirror using a polymer dispersed liquid crystal film according to the present invention.
여기에서, 하부기판(10)에 알루미늄을 증착시킨 알루미늄 증착층(40)이 형성되고 상기 알루미늄 증착층(40)위에 폴리머 액정층(30)을 형성되며 상기 폴리머 액정층(30)상에 상부기판(20)이 일체로 형성되어 있다.Here, an aluminum deposition layer 40 on which aluminum is deposited is formed on the lower substrate 10, a polymer liquid crystal layer 30 is formed on the aluminum deposition layer 40, and an upper substrate is formed on the polymer liquid crystal layer 30. 20 is integrally formed.
다시 말해서, 기존의 피디엘씨 (PDLC : Polymer Dispersed Liquid Crystal), 피엔엘씨(PNLC : Polymer Nematic Liquid Crstal)등과 같은 고분자 분산 액정필름의 구조에서 하부기판(10)과 폴리머 액정층(30)사이에 알루미늄중착층(40)이 형성된 것이다.In other words, aluminum is disposed between the lower substrate 10 and the polymer liquid crystal layer 30 in the structure of the polymer dispersed liquid crystal film such as PDLC (Polymer Polymer Dispersed Liquid Crystal), PNLC (Polymer Nematic Liquid Crstal), or the like. The intermediate layer 40 is formed.
또한, 상기 폴리머 액정층(30)의 상,하부측에는 전원을 인가하기 위한 투명전극(도시하지 않았음)이 도포형성되어 있다.In addition, transparent electrodes (not shown) for applying power are coated on the upper and lower sides of the polymer liquid crystal layer 30.
상기와 같이 구성된 고분자 분산 액정필름을 이용한 방현거울은, 폴리머 액정층(30)양측면의 투명전극에 전원이 인가되면 폴리머 액정측(30)내의 액정들이 전기장 방향으로 배열되고 상기 액정이 정상굴절률이 폴리머의 굴절률이 동일하므로 빛은 액정과 폴리머의 경계에서 산란되지 않고 투명하게 된다.In the antiglare mirror using the polymer dispersed liquid crystal film configured as described above, when power is applied to the transparent electrodes on both sides of the polymer liquid crystal layer 30, the liquid crystals in the polymer liquid crystal side 30 are arranged in the electric field direction, and the liquid crystal has a normal refractive index polymer. Since the refractive indices are the same, light is transparent without being scattered at the boundary between the liquid crystal and the polymer.
따라서, 상기 폴리머 액정층(30)의 빛 투과율이 다르게 되며, 투명전극에 인가되는 전원을 조절함에 따라 빛의 투과량을 조절할 수 있으므로 상부기판(20)을 통해 입사된 빛이 폴리머 액정층(30)을 투과한 후, 상기 알루미늄 증착층(40)에 의해 반사되어 다시 폴리머 액정층(30)과 상부기판(20)을 투과하여 외부로 반사되는 것이다.Therefore, the light transmittance of the polymer liquid crystal layer 30 is different, and the light transmittance can be controlled by adjusting the power applied to the transparent electrode, so that the light incident through the upper substrate 20 is polymer polymer layer 30. After the light is transmitted, the light is reflected by the aluminum deposition layer 40 and then transmitted through the polymer liquid crystal layer 30 and the upper substrate 20 to be reflected to the outside.
한편, 상기 폴리머 액정층(30)에 전원이 인가되지 않은 상태에서도 높은 투과율을 갖도록 한다면, 투명전극이 불필요하게 됨은 물론 전원의 인가 또한 필요없게 되므로 코스트가 적게드는 잇점이 있게 된다.On the other hand, if the polymer liquid crystal layer 30 has a high transmittance even when no power is applied to the polymer liquid crystal layer, the transparent electrode is not necessary and the application of the power supply is also unnecessary, which has the advantage of low cost.
이상에서와 같이 이 고안에 따른 고분자 분산 액정필름을 이용한 방현거울에 의하면, 폴리며 액정필름을 이용하여 방현거울을 형성하고 상기 폴리머 액정필름에 전원이 인가되도록 투명전극이 형성됨으로써 폴리머 액정필름에 전원이 인가되면 빛의 투과율이 변화됨에 따라 알루미늄 증착층에 의해 반사되어 오는 빛의 현란함이 없으며 이에 따라서 눈부심 현상이 최소화되는 것이다.As described above, according to the antiglare mirror using the polymer dispersed liquid crystal film according to the present invention, the antiglare mirror is formed using the poly and the liquid crystal film, and a transparent electrode is formed to supply power to the polymer liquid crystal film. When this is applied, as the transmittance of light is changed, there is no glare of the light reflected by the aluminum deposition layer, thereby minimizing glare.
또한, 효율에 따라 전원전압을 가변시켜 빛의 투과량을 증감시킬 수 있으므로 반사량이 가변되는 거울을 제공할 수 있으며, 투명전극이 형성되지 않은 고분자 분산 액정필름을 이용한 경우에는 코스트가 낮게 되는 잇점이 있는 것이다.In addition, it is possible to provide a mirror with a variable reflection amount by varying the power supply voltage according to the efficiency to increase and decrease the light transmission, and the advantage of low cost when using a polymer dispersed liquid crystal film without a transparent electrode will be.
