One：Fixed frame projector screen
The so-called picture frame projector screen, as the name suggests, the projector screen is fixed on the wall like a painting. Use an aluminum frame to make a frame similar to a frame, and then buckle the spring on the projector screen to make the projector screen flat. This is the simplest type of screen setup, all you need to do is fix it to the wall. The advantage is flat, much cheaper than electric pull screens. The disadvantage is that it can not be collected, it is easy to be polluted by dust, and it is easy to oxidize and discolor when exposed to the air for a long time. This is also the biggest drawback of this type of screen, because the position cannot be changed once installed. There is also the advantage of a fixed installation projection screen, which is that it is generally not easy to wrinkle, which maintains a smooth and flat projection surface. This kind of projector screen is suitable for a friend who has a dedicated audio-visual room and usually does not need to close the projector screen.
Two：Electric projector screen
Another type of retractable screen can be a manual or electric motor controlled lift (electric screen). The advantage of the manual screen is that it is cheap and easy to install. It can be considered when the quality of the screen is not high. The shortcoming is that during the long-term use, the “V” type ripple will occur due to the central pull-down force and other factors, which will affect the flatness of the screen. Moreover, for home users, it is difficult to ensure that the projector screen is in the same position every time, thereby affecting the picture effect.
The electric screen is the most common one in all kinds of products. The advantage is that it has good flatness and easy maintenance. The screen is evenly lowered from the two ends of the motor to ensure that the screen is not affected by external forces. It has the characteristics of easy lifting and easy installation. It can maintain the smoothness of the projector screen for a long time, and does not generate ripples for long-term use. The biggest disadvantage of this type of screen is the price, which is usually much more expensive than other types of screens, but people are still happy to use this type, after all, value for money.
Three:Electric tab tensioned screen
In the electric screen we have to mention the electric tab tensioned screen. This kind of projector screen is the most expensive in the household class. It adds a tension line on both sides of the electric screen to level the screen, while the upper and lower sides add strength by the heavy bottom edge. The advantage of it is of course the flatness (the tensioning of the screen is very important, it requires a lot of tension), and it can be put away, and the structure of the whole projector screen is very strong and very textured.
