Projection ratiou003dprojection distance/screen width. According to the farthest distance and projection ratio in actual use, the largest projection screen size that can be used can be calculated.  To build a home theater system in the living room, it is necessary to consider the impact of ambient light on the picture. For projectors with low output brightness, it is necessary to use a gain screen with reflection angle to improve the reproduction of picture details and colors. From the perspective of optical characteristics, home theater projection screens can be divided into three categories: diffuse reflection type, regression type and reflection type. The surface of the diffuse reflection curtain can reflect the incident light at irregular multiple angles and has a wide viewing angle. It is a curtain without gain. Various installation methods are applicable, including ceiling and horizontal installation. Both the regression type and the reflection type curtains are screens with gain, and there are many particularities in their use. When you build a living room theater, you should install it according to the characteristics of the projection screen. At the same time, you also need to consider the actual environment in the home.

Types of home theater projection screens  Currently mainstream home theater projection screens are classified according to the material of the screen, including textiles, plastics, and metals. Textiles and plastics belong to the same category, and are divided into white screens and gray screens according to the color of the curtain material. White screens can be subdivided into two types: Matte White with low gain and Glass Beaded with higher gain. The white plastic screen has accurate color reproduction ability, which can fully express the color reflected by the projector itself, and will not change the performance of the projector to the black and white transition. The gray screen is an improved screen material based on the white screen, which can absorb more ambient light, which can make the black level on the projection screen more solid, and the gap between black and white will also be widened, thereby achieving improved contrast But the gray screen material will change the performance of other colors, with a certain degree of color dyeing. The metal screen is a projection screen that is used completely for harsh environments, and it can get good color and detail performance in dark or bright environments.
