Your Guide to Buying a Projection Screen on the AliExpress
For a satisfactory video viewing experience, the quality of a projection screen (also called a projector screen) is as important 

as both the quality of the video itself and the quality of the projector being used to display it. Before purchasing a 

projection screen, consumers should know whether the projector that they will be using works by rear - projection or by front - 

projection. It is also important to know the size and the quality of the room where the images will be shown since each 

projector has its own throw ratio, which will affect the optimum distance between the projector and the viewing surface. The 

ambient light in the room will also be a factor to consider, including windows, doors, and other potential sources of light.

Another determination to make will be whether the screen should be portable or mounted. For consistent use in a home theatre, in 

a classroom, or in a conference room in an office or business, a permanent mount on the ceiling or the wall will often be the 

best option. For showing videos and slideshows in a variety of locations, a portable screen will be a better choice. Screens are 

available with operation that is either manual or motorized, and there are various sizes, aspect ratios, and fabric styles from 

which to choose. This guide will outline some basic information about the kinds of projection screens that are available, about 

what factors must be considered when making a purchase, and about how to purchase them at retail outlets like AliExpress.

Factors to Consider When Choosing a Projection Screen
The next sections of this guide will delve into some detail about the different factors that need to be considered when 

purchasing a projection screen, including whether the images will be projected from the front of the screen or from the rear, 

whether a fixed screen or a portable screen is desired, whether the screen will be operated electrically or manually, what kinds 

of screen fabrics are available, and what aspect ratio is optimal for the intended use of the screen.

Rear-Projection or Front-Projection
The first decision to make when searching for a projection screen is whether a rear - projection or a front - projection screen 

is desired. With a rear - projection screen, the projector is placed behind the screen, which provides a clean and effective 

image. Rear projection works best in a very large room, because the distance between the projector and the back of the screen is 

important for the clarity of the image. This requires a projector with a throw ratio that is consistent with the size of the 

space where it will be used. In addition, there must be a good deal of space behind the screen, and the space must be very dark.

Front - projection is most the common type of projection and is the easiest type to set up. Front-projection means that the 

projector is placed opposite the screen, and the images are projected onto the front of the screen. Among front-projection 

screens, there are ones that are portable and ones that are permanently mounted either to a wall or to a ceiling. Further 

choices among front-projection screens include whether the screen will be electric or manually operated.

Portable or Permanent Installation
Portable screens are the least expensive option that is available, and they are designed to be carried with ease from one place 

to another. They are also offered in a wide range of styles. They will be most desirable for presenters, instructors, and 

entertainers who travel a great deal for conferences, exhibitions, festivals, and other presentations. They are also suitable 

for spaces where it is impractical or impossible to permanently mount the screen to a wall or to a ceiling. Technology 

departments in schools, hotels, and conference facilities will benefit from portable screens because the flexibility that they 

offer allows spaces to be used for a variety of purposes. Portable screens are either pulled down on a free stand such as a 

tripod or are pulled up from a weighted base on a floor stand. Tabletop projection screens are ideal for professionals on the go 

who present to smaller groups.

Permanently installed screens can be mounted on a wall, suspended from the external surface of a ceiling, recessed into a 

ceiling, or even installed on the floor. Curtains are often added in front of wall-mounted units in a home setting to conceal 

the screen and to protect the surface when it is not in use. One type of permanent screen is the fixed-frame style, which is not 

collapsible and thus allows the manufacturer to use a thicker screen in its construction. Permanent screens are available in 

styles that can be opened and closed either manually or with an electric motor.

Manual or Electric Operation
Manually operated screens, also referred to as pull - down screens, are easy to set up, easy to use, and allow flexibility in 

using a viewing room for other purposes. They are also usually the most inexpensive choice. Manual screens are the most familiar 

style of projection screens because they are the style that is most used in classrooms. They roll up into a protective housing 

that can be semi-permanently mounted on a wall, they can be pulled down by hand similar to a window shade upon being ready for 

use, and they can then be raised back up into the housing. Manual screens are either tensioned or non-tensioned. Tensioned 

screens are set up to keep the screen fabric immobile and flat, whereas the fabric on non-tensioned screens hangs freely from 

the support structure. Non-tensioned screens are susceptible to movement from currents of air in the viewing room, which will 

cause imperfections in the projected images. Manufacturers of non-tensioned screens have added some features to manual screens 

to improve their quality, while maintaining their low costs and ease of use. One feature to look for is CSR, or Controlled 

Screen Return, which stops the screen from rolling too quickly back up into its case.

Electric screens are usually more high-end and expensive than manuals are (and are often more complex to install), as they can 

be mounted in a variety of ways, such as on a wall, on the external surface of the ceiling, recessed into the ceiling, or 

installed in the floor. They are usually larger than manual screens are, and they can be used in home theatres or in more public 

spaces like classrooms or business centers, where they can make an elegant, professional impression. Instead of being pulled 

down by hand from their protective housing, an electric motor raises and lowers the screen, usually through the use of a remote 

control or a switch that is mounted on the wall. Some projectors come with a feature connected to the screen that automatically 

lowers the screen when the projector is turned on and raises it when the projector is turned off.

Fabric Choices
The fabric that is used to make a projector screen is an important factor to consider when making a selection. The "gain" of the 

screen measures the reflectivity of light as compared to a screen that is coated with bright white titanium dioxide and has 

light being shone perpendicular at the screen. A gain of 1.5, for example, means that the screen reflects 50 percent more light 

than the standard. Screens with a higher gain will be more like mirrors, creating a bright "hot spot" in the screen’s surface, 

which is a magnified, blurry reflection of the projector’s lens. Low-gain screens reflect light more uniformly from the center 

of the screen to the edges and are best for home theatres, especially because today’s projectors tend to be very bright.

The fabric of the screen also determines the optimum viewing angle, which is a measure of the distance from the center of the 

screen to the edges at which the viewer can still see a quality image. Some screens reflect more light in the center and less to 

the sides, so the best viewing angle for screens of this nature is in front and perpendicular to the screen.

Another factor in choosing screen fabric is the image contrast, which is determined by the color of the screen fabric. Although 

grey screens can convey darker tones than white screens can, there is not much difference between the two if they are both made 

in a matte finish. A grey screen reflects less light, both from the projector and from the ambient light in the room, which in 

turn decreases the brightness of both the projected image and the ambient light and provides more contrast. Many manufacturers 

thus call their grey screens "high contrast" models, and these screens are appropriate for today’s powerful projectors.

Sizes and Aspect Ratios
Screens come in sizes ranging from 20 inches wide for tiny tabletop screens to 40 feet wide for high-end outdoor theatre 

systems. The size of the screen that a buyer is looking for will depend both on the screen’s intended use and on the size of 

the room in which the images will be projected.

Aspect ratio is another factor to consider. The aspect ratio of a screen is the relative measure of width to height. Square 

screens have an aspect ratio of approximately 1:1 and are most often used for data presentations and overhead projectors. Video 

format screens have an aspect ratio of 4:3, which is the same as most television and computer monitor screens. These screens are 

best for consumers who use both fullscreen and widescreen viewing. The ratio of HDTV screens is 16:9, which is the best format 

for home theatres since it is both the international standard format for HDTVs and offers the best match for widescreen film 

viewing.

Finding the Right Projection Screen
Once you have decided which kind of projection screen you want for your intended use, you will find that thousands of choices 

are available on the AliExpress. The most efficient way to find the right screen is to begin on the AliExpress home page, by 

entering the keyword phrase "projection screen" or "projector screen." You can then narrow your search by selecting a category 

like Office or TV, Video & Home Audio. The search can be refined further by clicking on one of the boxes under Type (such as 

Manual Screen or Fixed Screen), by selecting whether you want a screen to come with an included stand, or by what price or 

condition of screen you are seeking. Another way to shop is to select your category and then click on the brand name of the 

company that you favor.

If you already have a particular product in mind that you are shopping for, you can begin with a more targeted keyword search. 

For example, if you know that you want a fixed-frame screen from Elite Screens, for example, begin on the AliExpress home page 

and enter the keywords "elite projection fixed screen." To find a portable screen for use in the office, search for "office 

portable projection screen."

AliExpress's Search Tips page offers more suggestions for locating merchandise, and this list of AliExpress Stores will help you

Conclusion
Video and multimedia presentations are an important part of modern life, from home entertainment to classrooms to business 

conferences and seminars. In addition to possessing excellent images and projectors, users will need top-notch projection 

screens to ensure the highest quality viewing possible. When choosing a screen, consumers will need to have a thorough 

understanding of their needs in terms of size and portability, as well as good familiarity with the projector to be used and the 

space where the images will be shown. This guide has been intended to help the consumer to become familiar with some of the 

major factors that go into making the choice of which type of screen to buy.

Going into a brick and mortar store to check out the different models of projection screens that are available is a good idea, 

as it can give the consumer a sense of how the screens operate and what they look like, but that is not always an available 

option. Online shopping offers many advantages, however, and with the variety of projector screens that is available on 

AliExpress, anyone from casual viewers to professional presenters will be able to purchase the right equipment.
