With alfa screen technology independently developed by Guangfeng technology as the core, the anti light screen realizes the flexible display of Fresnel screen structure (only Fresnel hard screen is available in the world at present), and solves many pain points of traditional projection screen, such as low gain, bright spot and ghost shadow. Optical peak technology has applied for more than 50 patents for Alfa screen technology, covering many fields such as optical design, structure, technology and materials. < / P > < p > it is understood that at present, there are mainly Fresnel hard screen and black grid screen on the market. Based on different structures, the two kinds of light resistant screens have their own advantages and disadvantages. For example, Fresnel hard screen has high gain, good image quality and color, but “ghost” reflection is obvious, and 100 inch hard screen is inconvenient to install; although the side view angle of black screen is large, there is no reflection problem, but the gain is low, and the viewing effect is poor in daytime. < / P > < p > How can a single screen meet the requirements of high gain, good color, no obvious “ghost” and light installation at the same time? Based on this extreme experience, Guangfeng technology began to explore screen technology in 2013, and finally determined the research direction of flexible display. < p > < p > after years of research, Guangfeng technology has broken through the key technical characteristics of traditional screen such as gain and color, and has brought a new flexible Fresnel screen by using the original Alfa technology. < p > < p > at this conference, Guangfeng technology released two new fabulus series screens, namely fabulus 100 inch flexible Fresnel waveguide screen and fabulus color enhanced electric anti light screen. < / P > < p > 100 inch flexible Fresnel waveguide screen adopts optical peak Technology Alfa technology, which has clear display effect, strong resistance to ambient light, and easy to adapt to ultra short focus projection products with projection ratio between 0.2 and 0.3. The innovative design of the screen diaphragm is light and flexible, only 0.5mm thick, thinner than a coin. With the ultra narrow frame of < / P > < p > 8mm, the proportion of the screen is more than 98%, almost reaching the full screen. When using, there is no bright spot and “ghost shadow”, and the experience of watching the film is more extreme. < / P > < p > what is more worth mentioning is that the flexible Fresnel anti glare screen can be made into strip packaging and transportation because of its curlability, and the weight is reduced by more than 50% compared with the traditional Fresnel hard screen, so it can easily enter the elevator and corridor. < / P > < p > and Zhencai electric light resistant screen is also a product with a gain of 6 times. The screen has an absorption rate of more than 80% to the ambient light. It can clearly see the details of the dark field, with clearer picture quality and clearer levels. < / P > < p > in addition, the product also has arc-shaped self pulling system, which can ensure that the screen is flat at all times; in addition, the installation mode of wall hanging and lifting brings flexible and diverse DIY scheme design for users.
