The fourth generation of "ND" American nano high -definition sound-transparent screen imported [nano-HD] ND-woven transparent sound screen, (no distance English abbreviation "ND"), any distance viewing and projector distance have no moiré phenomenon, stone breaking Do not believe, cut the bottom to solve the troubles of moiré for many years. 
The fourth generation of American nano-HD soft screen is the original original fourth-generation US imported nano-HD soft curtain. It consists of a whole piece of thick imaging PVC. It has no bottom fabric, not only the brightness of the glass curtain, but also the stereoscopic transparency. Elite and soft, minimally visible, representing the highest quality of the screen. Please recognize that the real soft curtain is a bottomless cloth, and it is made with an expanded drawstring curtain or a picture frame pull curtain. (It is suitable for high-end home machines with sufficient contrast, JK recommends a white drawstring soft curtain). Features: color faithful reduction, clear and fine, high contrast, moderate gain; nano-effect: ultra-fine particles of nano-high-definition coating have exceeded the human eye's resolution range, making the image delicate, rich in three-dimensional sense, sharp and soft; soft screen effect: Very slightly visible. 
The fourth generation of American nano-high-definition glass fiber curtains used glass fiber woven base fabric instead of the traditional white plastic cloth to make the image a qualitative leap, the color faithful reduction, clear and fine optimization, good contrast level, nano glass curtain can produce pole Microscopic imaging with excellent image quality; 
The third generation of American high-definition sound- transparent screen JK imported from the United States through the high-density weaving of fibers, the tiny opening of more than 76,000 per square foot, to ensure high-quality sound transmission, its unique structure can effectively eliminate Moiré (interference fringes) produced when mated with the projector. It allows the speaker to be positioned directly behind the screen, without sacrificing HD high-definition images, while delivering unparalleled sound transmission. The third generation of American nano high-definition soft screen is the original original third-generation US imported nano-HD soft curtain. It consists of a whole piece of thick imaged PVC. It has no base fabric, not only the brightness of the glass curtain, but also the stereoscopic transparency. Elite and soft, minimally visible, representing the highest quality of the screen. Please recognize that the real soft curtain is a bottomless cloth, and it is made with an expanded drawstring curtain or a picture frame pull curtain. (It is suitable for high-end home machines with sufficient contrast, JK recommends a white drawstring soft curtain). Features: color faithful reduction, clear and fine, high contrast, moderate gain; nano-effect: ultra-fine particles of nano-high-definition coating have exceeded the human eye's resolution range, making the image delicate, rich in three-dimensional sense, sharp and soft; soft screen effect: Very slightly visible. 
The third generation of the US nano-high-definition glass fiber screen is imported into the US nano-high-definition glass fiber curtain. The base fabric woven from glass wool replaces the traditional white plastic cloth to improve the screen reflection technology. Because of the role of the glass fiber cloth, Increase gain and contrast. The color is bright, vivid and vivid, the color is faithful to restore, clear and fine, the contrast is high, the gain is moderate, and it can be said that it has excellent image quality. Nano effect: rich in three-dimensional, refined and soft. (1. For the authoritative analysis of home projectors in 2009, the contrast ratio is above 20,000:1. For the restoration of faithful colors, JK recommends using a white glass curtain. 2. If it is below 20000:1, it is recommended to use a gray glass curtain, gray. The curtain is darkened to make up for the lack of contrast, but for other colors, especially white, the reduction is not as good as the white screen). 
The second generation of high-definition glass fiber screen is imported from the United States high-definition glass fiber curtain. The base fabric woven from glass wool replaces the traditional white plastic cloth, which improves the picture quality through breakthrough. The glass fiber bottom layer makes the screen bright and beautiful. Increased, the picture quality is far better than the general screen. Features: bright and realistic, high contrast. (1. For the authoritative analysis of home projectors in 2009, the contrast ratio is above 20,000:1. For the restoration of faithful colors, JK recommends using a white glass curtain. 2. If it is below 20000:1, it is recommended to use a gray glass curtain, gray. The curtain is darkened to make up for the lack of contrast, but for other colors, especially white, the reduction is not as good as the white screen). 
Ordinary white plastic screen JK high quality white plastic cloth has a thick layer of woven base fabric, so that the screen surface is straight and does not deform. Applicable to the business education screen, fully meet the higher standards of business education.

The Led Display Screen used in special environment needs to be customized according to environmental factors, including severe cold, high temperature, damp heat, vibration, impact, exposure, rain, sand dust, lightning and other severe weather. For example, in the case of severe cold up to - 50c, the visual display will change the conventional configuration and materials according to the site environment, and replace them with high cold resistant materials.
