The overall design is very mature and stable, which also fits the positioning of its “living room TVâ€. The appearance of the atmosphere and a slightly technological sense is very significant in the living room.
The Ai Luowei VH410+ non-screen TV adopts ultra-short focal reflection imaging technology of free-form surface and can achieve 80-200 inches living room 3D cinematic effect. The 100-inch large screen presented by the VH410+ occupies a larger area in the human-eye viewable picture, and is closer to the actual visual experience of the human being, and therefore can provide a more realistic sense of presence.
The shocking viewing effect of the Ai Luowei VH410+ non-screen TV is not limited to the size of the screen. Its unique anti-ambient light characteristics are its essence. The VH410+ is equipped with a 90-inch polymer nano-light curtain. The light curtain is an optical screen that uses optical and physical properties to increase the contrast by shielding ambient light. The surface of the special physical structure and the light-absorbing coating can block 90% of the environment. Light, showing the true color of the projection, the contrast can be more than 10 times compared with white cloth.
In terms of content, Ai Luowei VH410+ screenless TV has a huge amount of online resources for viewing, with more than 100,000 episodes of TV dramas, more than 5,000 movies, and 1080P, 3D, Blu-ray and other high-quality resources.

Fresnel Lens (Fresnel lens), also known as threaded lens, is mostly a sheet made of polyolefin material, but also made of glass. One side of the lens surface is smooth, and the other side is engraved with concentric circles from small to large. , Its texture is designed according to the interference of light and the requirements of relative sensitivity and receiving angle.
Fresnel lens is equivalent to infrared and visible light convex lens in many cases, the effect is better, but the cost is much lower than ordinary convex lens. It is mostly used in occasions where accuracy is not very high, such as slide projectors, film magnifiers, infrared detectors, etc.
The Fresnel lens has two functions: one is focusing, that is, the pyro-infrared signal is refracted (reflected) on the PIR, and the second is to divide the detection area into several bright and dark areas, so that it can enter the detection area A moving object can produce a changing pyro-infrared signal on the PIR in the form of a temperature change.
