Make hard screen technology hard screen is the application of optical diffuse and Fresnel lens technology. The characteristics of the diffuse reflection of the screen is large viewing angle, low gain, ability to adapt to the ambient light is relatively strong, wide range of applications. One of the diffuse screen technology is directly on the plexiglass material - acrylic surface processing, screen angle and resolution are not ideal projection screen manufacturers offer solar effect is more serious. Another diffuse reflection screen technology is the use of acrylic, glass and other transparent material as the substrate, the rear surface of a soft paste made of screen. Vertical and horizontal viewing angle of the screen is 180 degrees, and the sun does not appear effect, and the size of this screen are generally relatively large. Fresnel optical lens screen is able to increase the gain of the screen, but the vertical viewing angles are subjected to certain restrictions. Fresnel optical lens Fresnel lens groove according to different screen from different angles, each screen has a different focus, in order to meet the needs of different lenses projector. 2013, XY SCREEN projection screen set up production plants in mainland China screen - Guangzhou-Yun audio-visual equipment, base set up in Guangzhou City, Guangdong Province, put into product categories are screen frame, curved frame screen, electric screen, folding screen projection screen manufacturers, simple screen, large-scale projects of electric and projector hanger; curtain material comprises acoustically transparent screen, 3D acoustically transparent screen, metal screen, high-definition soft screen, high-definition glass screen and so on. The company's main product projection screen, projector screen is mainly used in home theater, office culture, education, etc., welcome customers to consult. Perspective we know that reflection projection screen in all directions are different, farther away from the center of the screen, the lower the brightness; when the viewing angle luminance was reduced to 50%, we define it as perspective. Viewed in the perspective of the image, display the image brightness must be satisfactory; in addition to viewing angle projection, the projection brightness will be very low. In general, the greater the gain screen viewing angle is smaller; the smaller the gain, the perspective will be greater, the latter characteristic white plastic screen. Therefore, higher number of occasions in the show, we can use a small gain of white plastic screen, so you can play a wider viewing angle effect.
