VIVIDSTORM Ultra Short Throw December 25, 2020
Which is the best choice UST ALR floor rising screen for UST laser projector? VIVIDSTORM VS XY Screen Competition
1.Recognition from the projection distance of the projecto：
Since the general projection direction of the projector is linear projection, the ultra-short-throw projector can realize ultra-short focal length projection due to the special reflection design inside, and can project a large picture at a small distance. This is the most straightforward distinction.
Summary 1: A projector that can project a 100-inch image within 0.4 meters is defined as “Ultra short throw laser projector” or Laser TV.
2. Identify from the lens position of the projector
Generally, the lens of the projector is on the outside of the fuselage. The lens of the Ultra short throw laser projector is generally on the top of the projector, most of which are in the slot. Of course there is also a convex design.
Summary 2: Roughly Judge the “Ultra short throw laser project or” from the lens position.
. Smart System
It can also be recognized from other internal configurations, such as the use of light sources such as DLP or LCOS. The projector comes with smart movie-watching system (generally android system), Wifi, audio and other functions.
Summary 3: Compared with ordinary projectors, UST Laser projector is fully smart and functional.
Laser TV = high-brightness laser light source + ultra-short throw projection distance + ALR Screen
Please read the following buyer’s guide to select your favour Laser TV:
Back to the point, the biggest advantage of the Ultra short throw Laser projector is the anti-ambient light, but how to achieve this?
Since the projection method of UST laser projector is angled projection, due to the internal reflection lens design, the image is generally projected upwardly, which is different from the direct projection of ordinary projectors:
Because this kind of projector has a screen projection angle problem, it is about 45 degrees angle projection. Therefore, a special screen fabric was designed for this purpose, called UST ALR Screen fabric and Fresnel (Fresnel can be searched on Google). The screen has a sawtooth design, and the sawtooth is attached to the projection angle of the projector to directly help projection images directly into people’s eyes. At the same time, a light-resistant layer is designed on the screen fabric, which can effectively block or absorb ambient light.
If your projector is mounted on the ceiling, the screen material can be upside down, but the ambient light cannot be blocked, because the projector and the light come from the same direction, so you can only turn off the lights to watch the movie, but the picture effect is better than ordinary screens)
So, now you knew that if you use a UST laser projector, you need to use a special screen to get the best results. The most popular UST screen type is the motorized screen. and the coolest and popular is the Floor rising type.
Now we going to see some difference of UST screen materials:
