【Analysis of technical principle of professional rear projection hard projection screen】Engineering projection screen technology introduction
Why choose a professional rear projection hard screen? Because professional rear projection screens can show perfect images without being exposed to external light, professional rear projection hard screens need high gain, uniform color brightness, wide viewing angle, and no reflection of external light.
High gain:
High gain, we sometimes use light transmittance to explain, but high gain will affect the uniformity of image color and brightness. Therefore, when the gain is high, the color and brightness are still uniform before it can be called a good screen.
Wide viewing angle:
A wide viewing angle is essential. The cylindrical lens on the surface can control the light distribution in the horizontal and vertical directions, and has the function of expanding the horizontal viewing angle.
No reflection of external light:
The biggest advantage of the rear projection screen is that the external light does not affect the image quality. When the photoelectricity of the TV station and the external environment is strong, if the image is reflected, it will greatly affect the image quality.
Color and brightness uniformity:
The Fresnel lens on the back condenses the incident light into a balanced line to increase the uniformity of the screen, but the difference of the lens will also affect the uniformity of the color brightness.
Installation of rear projection screen
1. Taking into account the expansion coefficient of the acrylic material, the error of the rear projection screen size and the convenience of the rear projection screen installation, it is recommended that the size of the inner frame of the rear projection screen installation is 10-20MM wider than the actual size of the screen, such as : The actual size of the SVS WA1806 100' rear projection screen is 2083X1575MM. It is recommended that the size of the inner frame of the rear projection screen be at least 2083X1585MM.
2. Since the manufacturer has a different recommended value for the best image display area of u200bu200beach size of the rear projection screen, the requirements for the installation frame size of the rear projection screen will also vary due to the size of the screen.
