[A brief introduction to DIY-rear projection screen splicing and installation] Application skills
The projector screen is a home theater accessory second only to the projector in terms of price, and it has also attracted many home theater enthusiasts to DIY it.
Below we will focus on introducing the DIY projection screen.
In order to prevent the screen from being bent and deformed due to the gravity part falling below the screen for a long time during installation, the phenomenon of concave protrusions in the middle part occurs, and a small hole is placed on the top of the screen to press a metal strip during installation. And in the form of screw-fixed suspension, the gravity of the screen is transferred to the upper half of the screen. Then screws are screwed in from the inner side of the metal edge strip to the other three sides.
First, make an appropriate amount of small holes on the two sides of the splicing screen (depending on the splicing size). Then use a strong transparent rubber band or a thin wire rope to string the two screens together (above ), and then use one side of a metal shading board against the splicing part, and one side of the shading board against the splicing part, and then pull the wire rope between the two screens back and tie it tightly with the shading board as the supporting column rope. Pay attention to check whether the surface of the two splicing screens is flat and stable during operation. (The following figure)
