Description

거울을 갖는 디스플레이 화면{Display picture with mirror}Display screen with mirror

본 발명은 노트북이나 핸드폰등 액정 화면등에 쓰이는 평판 디스플레이 화면에 액정화된 박막 거울을 취부 하므로서 on-off시 거울 또는 본래의 화면이 나타나는 것에 관한것이다.The present invention relates to the appearance of the mirror or the original screen when on-off by mounting a liquid crystal thin film mirror on a flat panel display screen used in a liquid crystal screen such as a laptop or a mobile phone.

일반적으로 액정 화면은 유리나 초자등으로 된 압착 양면 구성의 두겹유리 등으로 구성이 되며 그 사이에 액정등이 내포 되어 전기적 신호 등에의해 작용하여 휴대폰이나 노트북등의 화면으로 쓰이고 있다.In general, a liquid crystal screen is composed of a double-layered glass, such as a crimped double-sided glass made of glass or glass, and the liquid crystal light is interposed therebetween and acts as an electric signal to serve as a screen of a mobile phone or a laptop.

또한, 디스플레이 화면을 보호하기 위해 화면의 전면에 한겹 더 초자면을 형성하기도 한다. 액정형 노트북이나 TV 등은 디스플레이 화면이 평판으로 이루어진 경우가 많으며 핸드폰등의 표면은 화면의 모서리가 둥글게 가공 되어 씌어지는 경우가 있다.In addition, in order to protect the display screen, an additional ultra violet surface may be formed on the front of the screen. LCD screens and TVs are often made of flat panel display screens, and the surface of mobile phones may be rounded off.

한편, 박막 형태의 필름이나 박판 거울은 필름이나 유리에 여러층의 박막을 입힌 스마트 유리나 필름 계통으로서, 텅스텐 산화물과 니켈및 리튬을 포함하는 전해질 박막및 투명 전극을 차례로 덮는 구조로서 전극을 이용해 ON-OFF시 리튬이 더해지고 빠지는 과정에서 디스플레이 화면이 투명과 불투명한 면으로 나타나게 된다. 따라서 투명 할때는 본래의 화면이 보이고 불투명 해질때가 거울면을 형성하게 되며 그 반대로도 구성이 될 수 있다. 한편 기존의 건축물용으로 쓰이는 전반사나 반반사 필름도 배면이 어두울때는 거울로의 사용이 가능하다.On the other hand, a thin film-type film or a thin plate mirror is a smart glass or film system in which multiple layers of thin films are coated on a film or glass. When OFF, lithium is added and removed so that the display screen is transparent and opaque. Therefore, when it is transparent, the original screen is visible and when it becomes opaque, it forms a mirror surface and vice versa. On the other hand, the total reflection or anti-reflection film used for existing buildings can also be used as a mirror when the back side is dark.

본 발명은 상기와 같은 필름이나 박판의 유리등을 이용하여 보다 더 유용하게 쓸수있는 디스플레이 화면의 거울로 적용코자 하는것이다.The present invention is to be applied to the mirror of the display screen that can be used more usefully using the film or thin glass as described above.

따라서, TFT-LCD 등의 초자류등의 디스플레이 화면에 박막의 필름이나 거울을 대용할수 있는 스마트 유리 계열등의 재료를 화면에 덧 취부하여 그 면이 전기, 빛등의 작용으로 ON-OFF시에 거울면화 하거나 또는 화면에 박막의 반반사 필름등을 취부하여 배면의 밝기에 따라 거울로 변환되어 사용될수 있는 장치를 구성함에 있다.Therefore, materials such as smart glass series that can substitute thin films or mirrors on display screens such as TFT-LCD, etc. are added to the screen, and the surface is turned on or off by the action of electricity and light. It is to construct a device that can be converted into a mirror according to the brightness of the back by attaching cotton or a semi-reflective film of the thin film on the screen.

상기한 바와같은 목적을 달성하기 위한 본 발명에 따른 거울 박막면은 본래의 TFT-LCD 화면등에 자막이 나타나는데 지장을 주지 않도록 화면의 전,중,후면의 부분에 그 거울면을 형성한다.The mirror thin film surface according to the present invention for achieving the above object forms the mirror surface on the front, middle, and rear portions of the screen so as not to interfere with the appearance of subtitles on the original TFT-LCD screen.

스마트 거울은 공지된 기술로서 전기나, 레이저, 빛 .열등의 신호에 따라 ON-OFF 신호가 주어지면 거울은 스스로 빛의 투과도를 조절하므로서 거울면이 형성 되는것으로, 유리나 필름위에 텅스텐 산화물과 전해질 니켈-텅스텐 산화물및 투명 전극을 차례로 입히는 것이다. 니켈 텅스텐 산화물은 전기적 신호에 의해 리튬이 첨가되면 투명해지고 본래의 디스플레이 화면이 나타나게 되며 제거되면 불투명 해진다. 따라서 불투명 한 상태의 면을 거울면으로 쓰게 된다. 또한, 전반사나 반반사 필름등을 취부한 거울면의 경우 화면이 켜져서 TFT-LCD 본래의 밝기에 따라 빛의 투과도가 달라져서 투명화되는 수단을 이용하여 본래의 화면이 켜지면 거울면이 사라지고 꺼지면 반반사 필름의 본래의 재질면이 거울면으로 형성되는 것을 수단으로 거울면에의 장치가 가능하게 되는 구성이다.Smart mirror is a well-known technology. When ON-OFF signal is given according to the signal of electricity, laser, light, heat, etc., the mirror forms the mirror surface by controlling light transmittance by itself. Tungsten oxide and electrolyte nickel are formed on glass or film. -Tungsten oxide and transparent electrode are coated in this order. Nickel tungsten oxide becomes transparent when lithium is added by electrical signals, and the original display screen appears, and when removed, it becomes opaque. Therefore, the opaque surface is used as the mirror surface. Also, in the case of the mirror surface in which total reflection or anti-reflection film is attached, the screen is turned on and the transmittance of light varies according to the original brightness of the TFT-LCD. It is a structure which enables the apparatus to a mirror surface by a means by which the original material surface of a reflective film is formed in a mirror surface.

상기한 바와 같이 노트북이나 TV , 휴대폰등의 TFT-LCD에 의한 디스플레이 화면에 거울의 작용이 있으므로 해서 평소에 거울로 사용할 수 있게 되는 면을 가지게 되므로서 위생이나 청결을 도모할수 있어 보다 더 디스플레이 화면을 유용하게 쓸수있는 효과가 있다.As described above, the display screen by TFT-LCD such as laptop, TV, mobile phone has a surface which can be used as a mirror at all times, so that it can be used as a mirror and promotes hygiene and cleanness. There is a useful effect.
