How to Choose a Led display Screen to attract your audience in 2021

Before we dive into this topic today, let me tell you the professional definition from wikipedia.org

A LED display is a flat panel display that uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors where they are visible in the sun for store signs and billboards. In recent years, they have also become commonly used in destination signs on public transport vehicles, as well as variable-message signs on highways. LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative (as opposed to informational) purposes. LED displays can offer higher contrast ratios than a projector and are thus an alternative to traditional projection screens, and they can be used for large, uninterrupted (without a visible grid arising from the bezels of individual displays) video walls. microLED displays are LED displays with smaller LEDs, which poses significant development challenges.

Due to the growing demand of modern digital display,  Led display screen (also called Led video wall) is widely used on various places, How to choose a suitable led display screen is always a headache for our clients, because there are a large number of type in the market. hence we conclude few way to help our clients to find the suitable screen according to their requirement based on the feature of each type of led display screens.

These features that decide which screen to use including the following: installation place, Ambient brightness, content to display, capacity of content, Viewing distance, Display proportion, below we will have a discussion for some of the point,

 

1, Difference on installation location, indoor or outdoor.

Led displays mainly used for advertising, broadcasting, we need to consider the place to install the led screen, based on the place, we can divide the screen to indoor, outdoor, semi-outdoor.

Indoor display screen screens likewise offer smooth screens that are optimal for ambient illumination as well as shorter watching distances. LED video wall surfaces make the interior setting extra interesting by supplying an incredible viewing experience– in retail stores, corporate entrance halls, and so on
. Besides normal indoor as well as exterior display screen screens, there are also semi-outdoor screens. These are seen in open halls, under eaves, sometimes below sun roofings and even under an outdoor canopy. However, despite providing the very same ultra-high brightness as outside LED screens, these semi-outdoor screens are not immune to negative weather.

Distinctions in between indoor as well as exterior LEDs

Outdoor LED displays are mainly utilized at places where a mega program gets on– for brand name ads, as an example, as they can provide full colour as well as really high brightness. Interior LED displays, on the other hand, can not attend to the requirements of mega exterior screen jobs but are excellent for interior applications. They supply far better spectrophotometric colour. Besides this, they also offer high colour saturation.

The elements that separate outside as well as indoor LED display screens are checked out in this write-up.

Brightness
This is certainly one of the striking distinctions between indoor as well as outdoor LED display screen screens. Bright sunshine can make it illegible boring or less brilliant LED indications. Thus, to provide ultra-high illumination, outside LED display screen screens are power-packed with numerous bright LEDs in one pixel. Since interior signs are not seen under the severe glare of the sunlight, they require to be much less intense, by default. Outside display screens use several times more brightness than indoor LED displays. Brightness is measured by systems called nits or candelas per square metre. The greater the luminance level, the higher the degree of illumination.

Durability to exterior weather
Exterior LED screen screens must be very leak-proof, water resistant, dust-proof, legible in sunshine, anti-lightning and resistant to high temperatures. Indoor LED screen screens do not require to supply the exact same resistance to the outdoors environment as well as thus do not included such features. The outdoor LED displays normally have IP65 water-proof levels while interior displays have IP20 waterproof degrees.

Display resolution
Outdoor LED screen display screens will certainly be generally viewed from more distances as contrasted to their interior equivalents, thus they have a lower resolution. Given that the range between the audience and an indoor LED screen is much shorter, usually, the resolution for interior LED display screens requires to be high. The greater the resolution the better the picture quality. The pixel pitch, which defines the density of the pixels on an LED display screen, is an additional differentiating variable between indoor and also exterior screen screens. Outdoor display screens have a bigger pixel pitch and a reduced resolution, whereas indoor display screens that need a high resolution for close watching have a smaller sized pixel pitch.

Points to keep in mind while selecting LED moving display screens
Interior LED screen displays can be created in a number of ways, depending upon the arrangement as well as building demands. This is because they do not call for a cupboard for setup. On the other hand, outside LED indications can not be put together panel by panel on the website. The entire installation is based upon the style (as a sign or billboard), or is put on a structure.

The sort of LED screen picked should depend on whether it will certainly be positioned indoors or outdoors. After that consider the dimension of the positioning location or installment site, check if there is a remote demand by means of a PC, and also find out the minimum or least viewing distance. The default design of interior LED display screens is for very easy and also quick combination with several input sources as well as third-party gamers. Nevertheless, exterior LED screen displays need a sturdy regulator or controller for playback functions. They are typically managed through a copyrighted software suite, which additionally provides remote access in addition to indicator diagnostics.

Screens with higher illumination are costly and also eat more electrical power. Therefore, it is very important to pick a screen with the right illumination for your needs, to ensure that you do not pay even more for something that is not essential. Non-weatherproof interior LED screens utilize LEDs with reduced light outcome, yet water-resistant outside LED screens need to make use of brighter LEDs.

what products we are providing in this category

1), Indoor single and dual display board, these kind of screen installed at indoor places, such as service counter at banks, postal offices,and government offices ,we can use products like model F3.75  and F5.0 indoor single and dual color screens.

2), Indoor full color led displays, these kind of screen also installed at indoor places, such as shopping center, cinema, showroom, in order to play all kind of advertising video and photos, we can use indoor Q2.5IS, Q3IS , Q4IS etc

3),outdoor led display screen, these kind of screen used at outdoor places, it consist of high brightness, high IP(ingress protection) grade, high display performance, which makes it the prior choice for outdoor display, mainly used at outside of shopping center, stadiums, commercial buildings, such as our outdoor Q5OS, Q6OS, Q8OS

4), As the technology growing up, new type and design of led display screen are invented to the market, such as indoor and outdoor led video floor, indoor and outdoor transparent screen, flexible led screen, etcs,

2,Led display screen Brightness required at different location

Based on the places of usage, different brightness should be chooses. CD is a numeric unit to metric 

Indoor ambient: ‚Č•600CD¬†

Semi-outdoor Under the Eave: ‚Č•3000CD¬†

Outdoor locationÔľąface the sun in morningÔľČÔľö‚Č•5000CD¬†

Outdoor (face the sun in afternoon): ‚Č• 6000CD¬†

3, Resolution of contents to show

The purpose of installing the video wall will decide to choice the resolution.

1), subtitles, depends on the size of text to decide the resolution.

2),Basic video : ‚Č•320*240

3), Standard Dvd Video: ‚Č• 640*480

4), Complete Pc monitor: ‚Č•800*600,HD 1080*720,2K, 1920*1080, 4K, 3840*1920

4, Display content and Viewing distance

What content to play should be consider before select the led video wall, the single slide content is limit even though the total content can be expanded.

Viewing distance also should be considered, if the audience are looking at a close distance, we should choose a small pitch screen, if the audience look at a far distance, we can choose a bigger size, but bigger pitch video wall.

Viewing distance calculation formula as below:

1„ÄĀMinimun viewing distance to see fluent photo(Meter) : pitch(mm) √ó1

2„ÄĀFarest viewing distance(meter): screen height(m) √ó30

For example , a customer bought a Q10 screen: width is 9.6m, height is 5.76m, please tell the minimum viewing distance, best viewing distance, and farest viewing distance.

Since we know the pixel pitch is 10mm, so,

The minimum viewing distance is : 10*1=10m

The best viewing distance is : 10*3=30m

The farest viewing distance is : 5.76*3=172.8m

5, Led display proportion calculation

In order to reach the best display performance, normally we use width:height proportion of 4:3, or 16:9, or nearest proportion.

For example a customer has a 70sqm screen, and he want to install it according to 16:9 proportion , there is a formula to calculate:

width=11.2m,

Height= sqm√∑width, so 70√∑11.2=6.25m

The above content is our many years experience in led screen field , today, I am sharing with you, so that you can help your customer to select the best led screen for customer,
