Transparent Reason For Transparent Vetrosa

     A foreign company applied the technology to its developed HTD-01 holographic transparent glass display, so that the back projection image technology has a better application prospects. The bottom of the glass screen is equipped with an LED projector, which can be projected onto a specially designed glass screen with a resolution of up to $number. This technology is very different from the general projection technology, the glass screen has a thin layer of metal foil material covered above, and coated with antireflection layer. And it has a great advantage, the screen can only show from a certain direction of the image, and the angle of the light will be ignored, even in the bright environment can clearly display the image, the previous back-projection technology can not do this.Transparent Vetrosa
    First, the electromagnetic wave, a kind of light, is the wavelength between 390 nm to 750 nm. In our usual sense transparent opacity is confined to this band. In fact, what you look transparent is not necessarily transparent to the electromagnetic waves that go beyond this band, and vice versa. For example, the X-ray is a very short wavelength of light, even the human body can penetrate, most of the matter is transparent to the X-rays. So, what determines the role of the light of matter, many factors, the most basic is the electronic structure of matter. We know that matter atoms are made up of atomic nuclei and electrons, and in fact electrons are very lively and can absorb photons to increase their energy. Once the light is absorbed, the substance behaves opaque. But not all light is absorbed, the specific choice is determined by the law of quantum mechanics. This involves the basic principles of solid state physics, including the energy band structure of solids and the transition between bands, in-band transitions and so on.Transparent Vetrosa
    Its electrons are not able to absorb visible light because of quantum mechanics, so the light penetrates directly into the past, thus presenting a transparent form. However, glass is not always transparent, for example, for some infrared and ultraviolet rays, glass is opaque, because the light glass can be absorbed. Another example is silicon, the semiconductor silicon wafer is black, because visible light will be absorbed, but silicon is transparent to most infrared, can replace glass. Metals are a special kind of example. Unlike most of the material mentioned above, there is a large number of free electrons that can run around (which is why metals can conduct electricity), so the effect of light is different.Transparent Vetrosa
