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.
