Everything You Ever Wanted to Know About LED Video Walls

LED Video Walls, in simple terms, are large-scale display systems seamlessly spliced together from multiple LED panels without the traditional screen’s bezel blocking them, and are able to form a complete visual canvas. This design brings a sense of immersion that is difficult to match with ordinary display devices.

 

Compared with traditional displays, it has outstanding advantages - sufficient brightness, durability, and the ability to be spliced into almost any size and shape according to demand. These features make it useful in more and more scenarios.

 

From TV studios and corporate command centers, to shopping malls, concert venues, and even churches and amusement parks, LED video walls can be seen. Choose a suitable LED video wall, not just change a set of display equipment, can make the brand image more prominent, and the audience interaction is smoother, daily use is also more hassle-free.

 

Next, I will be from the basic knowledge, application scenarios, product types, selection techniques, step by step and we talk clearly about the LED video wall related issues, to help you avoid misunderstandings, selected to fit their needs of the product.

 

What is LED video wall? Core foundation analysis

Definition and core technology

The core of the LED video wall is “seamless splicing”. It consists of a block of independent LED panels (also known as “splicing unit”) combined, no border between each panel, combined like a huge screen.

 

Its light source is a light-emitting diode (LED), the characteristics of this component determines the core performance of the video wall – high brightness, even in a bright light environment can also be clearly displayed; color reproduction is good, and can present a closer to the real picture effect.

 

This is essentially different from the LCD splicing screen, LCD splicing screen each screen has a border, put together there will be obvious black edges, destroying the integrity of the picture; and LED video wall does not have this problem at all, and in the size of the expansion of more flexible, do not have to worry about being limited by the size of a single screen.

 

The core components of the LED video wall

A complete LED video wall, not only the splicing panel, but also need several key components to work properly. Starting with the most basic LED panel, it is like a video wall of “building blocks”, each piece contains a LED lamp bead, driver chip and shell.

 

There are many choices of panel size and ratio, the most common is the standard ratio of 16:9, there are also some special scenarios that require customized dimensions, AVOE LED provides standard and customized panel solutions for different needs, which can be adapted to different installation spaces and display needs.

 

Pixel Pitch (Pixel Pitch) is a concept that many people tend to confuse, in fact, it is the distance between the centers of two adjacent pixels, the unit is millimeter. This value directly affects the clarity of the picture, the smaller the pitch, the denser the pixels, the clearer the picture, suitable for close viewing; the larger the pitch, suitable for long-distance viewing.

 

Specifically, 0.9mm-1.5mm small pitch products, suitable for studio, conference room, such as close viewing scenes; 1.8mm-2.5mm pitch, suitable for indoor medium-distance viewing, such as shopping mall counters, corporate lobbies; 2.9mm and above the large pitch products, more suitable for outdoor screens, stadiums, such as the long-distance viewing of scenes. AVOE LED has corresponding products in these three areas, which can cover the needs of different scenes.

 

Controller (also called processor) is the “brain” of the video wall, responsible for receiving external video signals, and then distribute the signal to each LED panel, to ensure that the whole screen picture synchronization, AVOE LED not only supports the industry’s standard controller program, but also according to the characteristics of their own products, recommend more suitable control program to ensure stable and smooth display effect. AVOE LED not only supports the standard controller program in the industry, but also recommends more suitable control program according to the characteristics of its own products to ensure stable and smooth display effect.

 

Mounting bracket and structure should not be ignored. A video wall display effect is no longer good, if the installation is not solid, splicing is not flat, will also affect the use of experience. AVOE LED’s mounting bracket has a standard and customized two kinds, no matter it is wall mounted, floor mounted or suspended, can ensure that the panel splicing precision, easy maintenance, and can be used for a long time stable.

 

Core application scenarios: LED video wall in which type of scene is the most practical

Entertainment and Event Scenes

LED video wall is almost standard in music concerts and tours. It can match the stage lighting, presenting cool visual effects, while the singer’s performance images are enlarged in real time, so that the audience in the back row can also clearly see the details on the stage.

 

The advantages of LED video walls are also obvious in movie theaters and sports stadiums. The big screen in the stadium allows the whole audience to see the details of the game, the score, replay and other information at a glance; LED screen in the cinema, color and brightness performance is better, can bring a more immersive viewing experience.

 

LED video walls in amusement parks are more flexible in usage. It can be used to display the progress of visitors, such as the lap count of roller coasters; it can also be used to play animations and notices in the public areas of the park to enhance the visitors’ playing experience.

 

Institutions and Public Spaces

Nowadays, many churches, temples and other religious places are beginning to use LED video walls. Installed in a conspicuous location, it can synchronize the display of hymn lyrics, scripture passages, or announcements for all believers to view, without relying on paper or small displays.

 

The use of LED video walls is also becoming more widespread on college campuses. Large screens at the entrance of libraries and teaching buildings can release campus notices and event information; video walls in laboratories can meet the needs of data visualization and experimental demonstrations, and help teaching and research.

 

Television studios and corporate command centers, the stability of the LED video wall and display effect requires more. The background screen of the studio needs to be uniform color, no flicker, to ensure that the texture of the live picture; command center of the big screen, to be able to real-time display of multiple monitoring signals, data charts and graphs, to provide clear visual support for decision-making.

 

Types of LED video wall: how to choose the right product to match the scene

Classification by display technology: direct display LED video wall

Direct display LED video wall is currently the most common type, we usually see in shopping malls, concerts, outdoor advertising, most of them are this kind. Its core advantage is a good display effect, high resolution, and strong resistance to strong light, in direct sunlight will not appear in the picture white, can not see the situation.

 

It has a wide viewing angle, no matter from the front, or side viewing, the color and clarity of the picture will not have obvious changes, suitable for use in scenes with a wide distribution of viewers. The choice of pixel pitch has a direct impact on its applicability to the scene.

 

For example, about 1.5mm small pitch direct display screen, suitable for close viewing, installed in the conference room, studio is very suitable, close look will not see obvious pixel dots; 3mm and above the pitch of the product, more suitable for long-distance viewing, such as gymnasiums, outdoor advertising screen, from a distance to look at the picture of the overall sense of stronger.

 

Classified according to the use of the environment: indoor vs outdoor LED video wall

indoor and outdoor LED video wall, the core difference lies in the ability to adapt to the environment, there are differences in pixel pitch, brightness, protection performance. Indoor scenes without direct sunlight, viewing distance is relatively close, so the pixel pitch of indoor LED video wall is usually smaller, the brightness does not need to be too high, focus on ensuring the clarity of the picture and color reproduction.

 

AVOE LED’s series are both specifically designed for indoor scenes.

Outdoor LED video wall, need to deal with sunlight, rain, dust and other harsh environments, so it must have good protection performance, usually do waterproof, dust-proof, anti-corrosion treatment. In terms of brightness, the brightness of the outdoor screen should be much higher than that of the indoor screen in order to display the picture clearly under direct sunlight.

 

AVOE LED’s series are specialized products for outdoor scenes. Their shells are specially treated to withstand wind and rain erosion, and their brightness is high enough to make the picture clearly visible even in the strongest midday sunlight, making them suitable for outdoor advertisements, stadium scoreboards, park entrances, and other scenarios.

 

Classification by shape: straight screen vs curved screen LED video wall

Straight screen LED video wall is the most conventional type, easy to install, relatively low cost, suitable for most of the standardized space, such as meeting rooms, shopping mall counters, command centers and so on. Its picture presentation is flat, can meet the daily display needs, is currently the most widely used modeling.

 

The advantage of curved screen LED video wall is more immersive, suitable for some scenes with high requirements for visual experience, such as movie theaters, science and technology museums, high-end brand exhibition halls and so on. It can fit the human body’s visual habits, so that the audience, no matter in which position, can feel a more three-dimensional picture effect.

 

However, the degree of customization of the curved screen is higher, the installation is also slightly more difficult, the cost will be higher relative to the straight screen. AVOE LED can be customized according to the customer’s space and demand for different curvature curved screen LED video wall, not only to ensure the integrity of the picture, but also to meet the needs of creative display.

 

LED vs LCD video wall: which one to choose?

Comparison of core parameters

Many people in the selection of video wall, will be entangled in the LED and LCD which is better. In fact, both have their own characteristics, the key to look at the use of the scene. First of all, from the most intuitive bezel, LED video wall is seamless splicing, no bezel blocking, the picture of the overall sense of strong; and LCD splicing screen each screen has a bezel, there will be a clear black edge after the splicing, affecting the integrity of the picture.

 

Brightness, LED video wall brightness is higher, usually more than 500cd /㎡, and even up to 1500cd /㎡, suitable for outdoor, bright light environment; LCD splicing screen brightness is generally in the 300-500cd /㎡, easy to whiten in direct sunlight, more suitable for indoor low-light environment.

 

Expansion, the advantages of LED video wall is obvious, can be spliced into any size and shape according to the demand, such as oversized outdoor advertising screen, irregular indoor modeling screen; LCD splicing screen expansion by a single screen size limitation, it is difficult to be spliced into a large size or special shape of the screen.

 

Durability and service life, LED video wall structure is more robust, can adapt to 24-hour uninterrupted operation, the service life is usually in 60,000-100,000 hours; LCD splicing screen is relatively fragile, long-term uninterrupted operation is prone to failure, the service life of the general in 30,000-50,000 hours.

 

Maintenance and color accuracy, LED video wall module support before and after maintenance, maintenance and replacement is more convenient, and high color reproduction, especially high-resolution products, color performance is better; LCD splicing screen can usually only be maintained on the back, the maintenance needs to reserve enough space, color performance is good, but there is still a gap compared with the LED video wall.

 

Conclusion: When to choose LED, when to choose LCD

Comprehensively, in most scenarios, the LED video wall is a more secure long-term choice, especially for high-specification scenarios with high requirements for display effect, stability, and scalability, such as outdoor advertisements, studios, command centers, and large-scale event sites. Although its initial investment may be slightly higher, but long service life, low maintenance costs, long-term use of more cost-effective.

 

There are only a few special cases where LCD splicing screens may be more appropriate. For example, the budget is limited, and the use of time is not long, just short-term temporary use; or limited installation space, can not reserve space for maintenance of the LED video wall, and the requirements of the integrity of the screen is not high. In this case, LCD splicing screen can be used as a temporary solution, but long-term use is still recommended to prioritize the LED video wall.

 

How to choose the right LED video wall? Step by step to teach you to choose

First clear use of the scene and environment

The first step in selecting the LED video wall, the first step is not to look at the parameters, but to think clearly about their own use of the scene. Is it placed indoors or outdoors? How far is the viewing distance? How many viewers? These questions directly determine the subsequent selection of parameters.

 

For example, placed in the indoor conference room, viewing distance is generally 3-5 meters, the number of viewers is not much, it is suitable for small pitch, high resolution products; if placed in the outdoor plaza, viewing distance of more than 10 meters, the audience is widely distributed, the need for large spacing, high brightness, good protection performance products.

 

In addition, but also consider the type of content displayed. If the main playback of video, pictures, high color and clarity requirements; if only display text, data, the resolution requirements can be appropriately reduced, focusing on ensuring that the text is clear and stable display.

 

Determine the core parameters

Pixel spacing is one of the core parameters, which has already been mentioned, it is directly related to the viewing distance. Simply put, the closer the viewing distance, the smaller the pixel pitch. For example, if the viewing distance is about 3 meters, a pixel pitch of 1.8mm-2.5mm is more appropriate; if the viewing distance is more than 10 meters, a pixel pitch of 2.9mm and above is acceptable.

 

In terms of size and ratio, the common ratio is 16:9, which is suitable for playing regular video and picture content. If there are special needs, such as fitting irregular wall surfaces or displaying content with special ratios, you can choose customized sizes and ratios. AVOE LED can provide personalized size customization services according to the customer’s space and needs.

 

Brightness parameters also need to be adjusted according to the usage environment. For indoor low-light environment, a brightness of 500-800cd/㎡ is sufficient; for indoor strong-light environment (e.g., near a window with direct sunlight), the brightness needs to be above 1000cd/㎡; for outdoor environment, the brightness usually needs to be above 1500cd/㎡ to ensure the picture is clearly visible.

 

Consider installation and maintenance costs

There are various installation methods, such as wall mounting, floor mounting, hanging (rigging) and so on. Different installation methods have different costs and requirements. Wall-mounted and floor-mounted installation is relatively simple and low cost; rigging requires professional bracket and installation team, relatively high cost, and has certain requirements on the installation environment, such as the weight-bearing capacity of the ceiling.

 

Maintenance, to consider the later maintenance convenience. LED video wall module support before and after maintenance, later replacement of faulty modules, without disassembling the entire screen, more convenient and quicker. When selecting products, it is important to confirm the maintenance of the product and whether the manufacturer provides perfect after-sales service.

 

In addition, the daily maintenance is also very simple, mainly regular dust removal, keep the environment temperature stable, to avoid overheating equipment. These details are simple, but can effectively extend the service life of the equipment and reduce the probability of failure.

 

Budget planning: what factors affect the price

LED video wall price is not a fixed standard, affected by a number of factors, it is difficult to directly give an accurate quote. First of all, the size, the larger the size, the greater the number of panels required, the higher the price is naturally. For example, a 5 square meters of video wall, and a 20 square meters of video wall, the price difference will be very obvious.

 

Pixel pitch is also an important factor affecting the price, the smaller the pixel pitch, the higher the technical difficulty, the more expensive. For example, 0.9mm pitch products, the price is much higher than 2.9mm pitch products. However, this does not mean that the more expensive the better, the key is to fit their viewing distance and use needs.

 

Installation and modeling will also affect the cost. Hanging is more expensive than wall mounting, and curved screens are more expensive than straight screens, as these require customized brackets and mounting solutions, and are more difficult to construct.

 

There are also content-related costs, for example, if the proportion of the video wall is more specific, you may need specialized video processing equipment to adapt to the content display, this part of the equipment also needs to be factored into the budget. If you do not have a professional design team, you also need to consider the cost of having a designer to produce promotional content.

 

LED Video Wall Maintenance: Practical Tips to Extend Service Life

Daily Routine Maintenance Tasks

The daily maintenance of the LED video wall is very simple and does not require much time and effort. The most basic thing is to remove dust regularly, because too much dust accumulation will affect the heat dissipation and display effect. You can use a dry soft cloth or special dusting tools, gently wipe the screen surface and border, pay attention not to exert too much force to avoid damage to the screen.

 

It is also important to keep the environment temperature stable. LED video wall will produce a certain amount of heat during operation, if the environment temperature is too high, it will affect the stability of the equipment and shorten the service life. It is recommended that the temperature of the installation environment is controlled between 10-35℃, to avoid equipment running in a high temperature environment for a long time.

 

As a special reminder, the screen should never be cleaned with water, nor with liquids containing alcohol, detergents and other chemical ingredients. These liquids can easily penetrate into the interior of the screen, leading to short-circuiting of electronic components and damage to the device. If there are stubborn stains on the surface of the screen, it is recommended to gently wipe it with a dry soft cloth or contact the manufacturer for professional cleaning advice.

 

Long-Term Maintenance Points

For long-term maintenance, first of all, follow the manufacturer’s maintenance manual strictly and do not disassemble the device by yourself. If the device is malfunctioning, such as screen flickering, black screen, color abnormality, etc., do not disassemble the device for maintenance by yourself, you should contact the manufacturer’s after-sales service team in a timely manner, and have it repaired by professional personnel.

 

For faulty panels, driver chips and other components, replace them without delay. If a module fails and is not replaced in time, it may affect the display effect of the whole video wall, or even lead to the failure of other components as well. AVOE LED will provide customers with sufficient spare parts to ensure that failures can be handled in time.

 

Under normal circumstances, the service life of the LED video wall is 60,000-100,000 hours, if properly maintained, the service life can be further extended. For example, by regularly checking the line connection and heat dissipation of the equipment and dealing with potential problems in a timely manner, you can effectively reduce the probability of failure and allow the equipment to run stably for a long time.
