Modern applications of LED display systems
No wonder, LED display systems have become an integral part of everyday lives. You can find them in major places such as sports arenas, shopping malls, billboards, etc. So, what are LED displays and their structure? Are there benefits of using them? Let's find the answers in this post.
Typically, an LED display is referred to as a screen display technology. This technology uses panels of LEDs as the main source of light. Electronic devices regardless of big and small are using LED display technology. These are used for interaction between the users and the display systems.
For commercial use, an LED display system constitutes the main screen display that you find around displaying advertisements everywhere. LED displays are known for their low power consumption and efficiency. In a massive LED display, you can find plenty of LED panels that consist of several LEDs.
Apart from using low energy, LED displays come with greater light intensity. Additionally, they have amazing brilliance as well. This is the reason why they are used in public places as commercial products.
Led display systems have two important parts: An LED panel and a controller. The primary LED panel comes with multiple display units of LEDs, referred to as LED panels or LED cabinets. They are connected and constitute the main body of the LED display system.
So, that was everything about the LED panel. Speaking about the controller, it can be segregated into two parts. The controller includes the control board that represents the hardware and the control system that represents the software. A small computer, a receiving card, and a sending card are the components that you will find on the control board.
A wide range of cabinet units or display panels with separate controllers and specifications can become a part of the LED displays. They come with different control technologies and fulfill the demands of different types of applications in various environments. Some examples could include multifunction cards and video processors.
When it comes to comparison between traditional displays and LED display systems, the main difference is in the backlights. While traditional displays use fluorescent backlights, LED displays use light-emitting diodes in place of backlights. As such, LEDs will have a better picture quality and be available in varying configurations.
Traditional displays give mediocre to poor visual performance when not viewed within the right viewing angles. The image produced on the display will consist of blurry lines, unsettling brightness, and poor contrast. Although LED displays have fewer viewing angles compared to traditional displays, LEDs influence the image quality to a great extent.
The power used by traditional displays and LEDs will depend on certain factors such as the brightness of the display, build quality, screen size, resolution, power-saver settings, etc. There is no denying that bigger displays with large resolutions will consume more power. Still, LED displays are more efficient than the traditional displays.
Below listed are the benefits of using LED display systems.
LED systems use high-end technology that not only gives performance but also is extremely reliable. These systems that are designed for digital billboards have changed the way things were a few years ago.

These display systems are lightweight and provide realistic, high-quality images.
Low energy consumption is what makes these systems amazing. They are eco-friendly options and help businesses reduce costs.
There is no limit to the size of LED display systems when it comes to installation. In terms of delivering advertisement messages, they can display as big as you want them to be.
An LED display system will have a prolonged lifespan compared to traditional systems.
The main purpose of LED display systems is to illuminate places and objects with advertisements. Because of their massive sizes, low energy consumption, flexibility in usage, and extended lifetime, LED displays are almost everywhere these days.
Therefore, they are widely seen in LED display boards. These commercial, massive boards are a common sight these days and you can find them almost everywhere. Also, these boards are used outdoors as storage signs, storage signs, billboards, etc. On sign boards, you can find several languages that convey the signals. You can find these LED systems in airports, arenas, shopping malls, and many more.
LED displays are widely used in commercial advertising, sports events, transportation, education systems, railway stations, airports, shopping centers, hospitals, hotels, real estate markets, corporate management, and other public service venues. What are the advantages and disadvantages of LED display?
1. Traditional display
Before the appearance of LED full-color screens, various display tools were invented one after another, such as Inkjet billboard, animate billboard etc.
Among them, the display devices connected to the computer host can basically be divided into CRT, LCD, PDP, LED, OLED&#;and 3D etc.
2. Advantages of LED screen
LED screen is a perfect combination of LED display technology and video processing technology, which represents the latest displaying technology. Compared with traditional media, a new generation of integrated media has many significant advantages:
(1) Adjustable High brightness, and large viewing angle
For Indoors application: When we play a projector or TV wall during the day, we need to draw the curtains and endure the darkness and occlusion, otherwise the screen will be blank and the content can hardly be seen. This is mainly due to the low brightness, plus the viewing angle is limited.
The brightness of the LED full-color screen is four or five times that of ordinary projectors.The environment can play content very easily, while keeping the room spacious, bright and airy. In addition, the vertical and horizontal viewing angles of the LED full-color screen are both 140°-160°, which means that the viewing angles of almost all positions. The audience has a good viewing effect, which is also unattainable by other display devices.
(2) Dynamic video, large amount of information, bright colors and realistic displaying effects.
Human eyes are often more sensitive to dynamics, so it is also an outdoor medium, LED screen advertising are easier to attract the attention of the audience, so that customers who place advertisements can get higher returns. The content played by the LED screen is generally stored in the computer hard disk, so the capacity is large and supports long-term video playback; At the same time, because the LED full-color screen can display 16.77 million colors, it can restore the true colors of the video to the greatest extent, which is vivid and shocking.
(3.) The size is not limited, the shape is free to meet the creative needs
Many media are simple to make small, but very difficult to make big, and technical bottlenecks will follow. The LED display is assembled like building blocks, which is simple and convenient, and more importantly, there is no limit to the size. The larger the screen, the more domineering effect. And because the screen is composed of individual boxes, different shapes can be built according to the designer&#;s creative ideas, and after the construction, the same or different video content can be played as a whole according to the original design. This is also one of the main reasons why LED full-color screens are especially fond of the various Festival, concert, etc innovative stages over the years.
(4.) Long lifespan, strong in usage
The life of the LED is 100,000 hours, which can be continuously lit for 11.4 years; and the LED belongs to the firmware, and its anti-shock and anti-vibration ability is much stronger than other devices.
(5.) High End, can enhance the user&#;s brand images.
3. Disadvantage of LED screen
1. The main concern for outdoor led screen is Light pollution. Because the screen is too bright, the illumination at night is the same as during the day. Good news is that we can use Light sensor or setting in the operation system to automatically detect changes of the environment brightness, and automatically adjust the brightness of the screen, to try to avoid light pollution. In this way, screen can protect the environment at the same time saving power consumption.
2. Second, the led screen price is higher than traditional advertising way.
3. Compared with the traditional way, led display power consumption is higher.
