Description

Transflective glass

The invention relates to the technical field of energy saving, in particular to a transflective glass.

With the upgrading of products in the touch screen display industry, the optical film on its devices is no longer a simple conductive film in the traditional sense, but needs to have both special optical characteristics and functionality, and transmittance and reflectance. , Film color, film surface hardness, corrosion resistance, etc. all put forward strict requirements. However, the thickness of a single layer of an optical film is generally on the order of nanometers, especially how to design a film system, how to ensure the repeatability of mass production of a film layer, etc., for most companies. No easy task.

In addition, the multi-function mirror display technology is the core technology of mirror TV, and the amazing hidden picture function runs through most products. Using advanced magnetron sputtering technology, the surface is coated with a metal mixture to make it reflective and transparent, that is, the strength of light and the self-identification ability of the human eye are used to achieve a mirror effect after shutdown. Show the magical effects of HD images.

For most elderly people in the family today, watching TV for several hours a day has become a part of them, and people especially hope for the birth of a new type of TV. Nowadays, the multi-functional mirror TV gives you a different experience. Turning on is the TV, turning off is a mirror, and life is so elegant and natural. And it can be installed in the bathroom and the sink. More worth mentioning It is a multifunctional mirror display that can be touched, so it brings more functions, for example, you can add applications on the TV, and you can measure blood pressure, heart rate, etc. at home.

Imagine using a mirror TV to implement various applications, such as watching movies, checking maps, writing documents, watching weather forecasts, and measuring health ... this is a multi-function mirror display.

Mirror organic screens have a futuristic feel. Mirror TVs are coated with a metal film under the transparent LED panel glass and reflected by the metal film to form a picture. Compared with the liquid crystals currently on the market, mirrored organic screens have better brightness, sharpness, contrast, and response speed due to their self-luminous characteristics. When the LED screen is used as a mirror organic screen, the reflectance is as high as 90%, while the ordinary LCD mirror organic screen has a reflectance of 50%, or even less than 80% of the ordinary mirror. When the LED panel is used as a mirror display, The effect is better.

The two functions of the mirror TV make it unique. When the mirror TV is turned on, the image can be displayed in the mirror; when it is turned off, it can be used as a mirror. It is currently used more in hotels. Mirror TV can also be applied to the surface of different display systems such as rear projection, digital tube display, mobile phone screen, computer display, TV screen, etc., so as to realize the mirror display effect, and can also be combined with daily life to generate smart mirrors, etc. A series of smart products.

Multi-function mirror display, the most prominent feature is still on the "mirror". Imagine that when we walk into the bathroom, we can see information including time, weather or email in the mirror on the wall, and at the same time we see ourselves surrounded by rows of text and images. What is it like? Anything you can do with your phone or tablet, mirror TV can do the same. At this time it is not just a display screen that can be used as a mirror, it will become your loving tablet. With a mirror TV, the cool and magical vision you imagine will be fully displayed in front of you.
