Recently, looking at a white wall in the bedroom, I fell into thinking. In my plan, this white wall is left for the projector. At first I planned to install an electric curtain, and then I found that I had to use an expansion hook to connect to the power supply, but there was no wiring duct at all on the top of the wall. After

, a ground-pull-type mobile screen was temporarily inserted. There was no problem when using it. It was always necessary to clear the storage box under the wall. After a while, I didn’t feel like watching the movie. The most important thing was that the screen was curled. Originally, the picture was just a comfortable one, but it was really too troublesome to go around. After thinking about it, you still have to hang the curtain directly on the wall, that is, the curtains of frames.

Considering the projector model I put in my bedroom now, I did not choose the traditional projection screen again, but tried the anti-light curtain. The advantage of

anti-light curtain is that it can greatly alleviate the problem of light interference, and can have a better picture effect during the day without having to pull the window, which is very in line with my current needs. Next, I will share the Fist S1 picture scroll optical screen I just replaced, hoping it will be helpful to all of you.

is not difficult to install

Because of the special nature of the Fist S1 picture optical screen, it adopts a curly packaging. However, because the product itself is relatively fragile, even if it contains pearl cotton and foam reinforcement, it is still easy to break. You must unbox the current logistics surface to sign for it. In addition to the S1 scroll optical screen and magnetic suction sheet in the box, the manufacturer also includes a bunch of installation tools, including hanging accessories, spools and tape for positioning the installation position, two pairs of gloves and a wipe cloth.

where the magnetic patch is a double-sided structure, the front is a magnetic force, and the red part on the back is 3M glue, so it can be used by tearing it apart.

The specific installation method can be scanned to view the QR code on the outer packaging box, or the manufacturer's installation service allows staff to install it on the door. In fact, the entire installation process is not difficult, I easily handled it myself.

First we need to select a wall, which is slightly larger than the Fist S1 scroll optical screen, that is, it is greater than 1786*1010mm.

sews two pieces of wires larger than the width of the optical screen of the S1 scroll from the spool, tie them on one end and attach them on the tape. Then measure the distance of the optical screen of the Fist S1 scroll on the wall (1786mm), mark it, and then paste the two lines onto the wall according to the marked distance.

Use the projector to load the installation positioning diagram provided by the S1 scroll optical screen, adjust the projection position between the vertical lines, and then return to the wall to mark the 6 grids respectively.

Remember to mark this step, and then measure and confirm the installation size repeatedly. Because it is not convenient to tear off after applying magnetic stickers, even if it is a bit crooked, it cannot be adjusted. Once tearing, it will definitely involve a large piece of wall skin.

According to the first 6 positioning grids, six magnetic forces are embedded on the wall in turn. Although you do not seek perfect fit, you should not exceed the grid in general. The key is to leave a yellow bottom edge around. If you find bubbles, just use a utility knife to pierce it.

What should I do if I accidentally post it wrongly? At this time, you can directly apply a ruler, scissors, and paper-removing knife. Just trim the magnetic sticker manually to ensure that the magnetic sticker is placed in the yellow frame, but do not try to stick the block and tear it off.

Finally, "place" the Fist S1 scroll optical screen before the magnetic patch, and it will attach itself without drilling the hole and screws. Then adjust the position left and right to center the projection screen.

Note that the S1 scroll optical screen has an installation direction, the forward casting is the arrow upward, and the hoisting is downward.

Simply put, we must first measure the size of the Fist S1 scroll optical screen on the wall, stick a magnetic sticker according to the projected installation positioning map, and finally hang the S1 scroll optical screen. It should be noted that because the thickness of the Fist S1 scroll optical screen is only 1.2mm, you must choose a flat wall, otherwise it will affect the projection effect.

Fest S1 scroll optical screen adopts Fresnel optical microstructure, which mainly changes the light refractive path to direct the diffuse reflection loss light, achieving a clear and bright picture. This is why it is necessary to distinguish between forward projection and lifting directions during installation.

In addition, products similar to Fister S1 picture scroll optical screen will have visual angle problems and are not suitable for large-angle side projection. The best installation is to be positive.

wall projection effect

From the final result, we can see that the border of the Fist S1 scroll optical screen is extremely narrow, and the four corners are also rounded. From a distance, it only leaves a black border line.

Compare

First of all, it is a real photo of not pulling curtains during the day. You can see that when you only cast a white wall, you can only see a rough outline of the character on the screen, and when you encounter a dark picture, you can no longer watch it normally.

After switching to the Fist S1 scroll optical screen, the picture has undergone significant improvement. It turns out that the picture covered by white mist can finally be seen clearly. Even the black-bottomed picture is just covered with a layer of mist, which has little impact on watching the movie.

After pulling the curtains, turn on the ceiling light in the bedroom . At this time, the white wall picture will be slightly improved, but it is only barely visible.

After switching to the Fist S1 scroll optical screen, the color becomes fuller. In terms of light resistance, the strong light environment no longer seems too gray and there is no obvious reflection phenomenon.

compared with

When I came to the night environment, the white wall effect was still relatively excellent at this time, but it was still a bit far from the effect I wanted.

When playing the video, the black blocks on the upper and lower ends were finally displayed normally. It is obvious that the optical screen has a large differentiation in terms of brightness and contrast.

is written at the end

as an 80-inch Fist S1 scroll optical screen. It solves the problem of my poor viewing effect during the day, and the image quality is better than the white curtain and white wall. Of course, this is based on the projector's own lumens are not high. If it is a high-end projector and the home environment is relatively good, just cast the curtain directly.

The lighter weight also makes the installation of the S1 scroll optical screen quite simple. Just stick a magnetic sticker and hang it on, without having to punch holes on the wall. However, after installation, it will still cause damage to the wall, and the area is not small, and it will be exposed and large. In addition, the thickness of only 1.2mm also makes it relatively fragile. Although it has a 2H level hardness, it should still be avoided from collisions.

I thought of a way to directly paste the Fist S1 scroll optical screen onto the mobile whiteboard rack, so that I can move around. But where should I place the whiteboard rack when I am not in use? This is another new question. I am Nicholas lalala, bringing more interesting objects.
