مقدمة
As the core hub of modern urban management, emergency response, military operations and other fields, the command and dispatch centre has put forward extremely high requirements for display equipment.
So, what makes small-pitch LED display screens a “rigid need” for command and dispatch centres?
1. What is small-pitch LED display technology?
In short, small-pitch LED display screens are indoor LED display screens with very small distances between pixels. This “small” specifically refers to pixel pitches of P2.0 mm and below.
The pixel pitch is the centre distance between two adjacent pixels on the screen. The smaller the pixel pitch, the higher the screen دقة, and the clearer and more delicate the display effect.
Small-pitch LED display screens can be divided into several types according to different pixel pitches, such as P1.2, P1.5, P1.8 and P2.0.
- P1.2:
The pixel pitch is only 1.2 mm, the picture is super clear, and the details are extremely detailed. It is especially suitable for high-end conference rooms and radio and television studios, which have particularly demanding requirements for picture quality.
- P1.5:
Pixel pitch is 1.5 mm, the picture quality is also excellent, and the cost performance is relatively high. It is often used in places that require a high-definition display, such as exhibitions, control centres, and monitoring rooms.
- P1.8:
The pixel pitch is 1.8 mm, which not only guarantees the picture quality but also takes into account the cost. It is suitable for medium and large conference rooms, commercial advertising displays, stage backgrounds and other occasions.
- P2.0:
Pixel pitch is 2.0 mm, which is the entry-level model of small-pitch LED display, but the picture quality is still better than many traditional displays. It is very suitable for information bulletin boards such as hotel lobbies, airports, and cinemas.
1). Technical principles and characteristics of small-pitch LED display
1.1). Pixel-level point control technology:
The small-pitch LED display uses pixel-level point control technology, which means that it can finely control the brightness, colour, and uniformity of each pixel.
Just like you adjust the display settings of a TV or computer, the small-pitch LED display is automatic and adjusted more precisely.
This technology ensures that the display can achieve very high clarity and consistency when displaying videos and images, making the picture look more real and natural.
1.2). High refresh rate display technology:
The refresh rate of small-pitch LED displays is particularly high, usually much higher than that of ordinary displays.
The refresh rate refers to the number of image frames refreshed per second on the screen. The higher the refresh rate, the smoother the picture looks and the brighter the colours.
High refresh rate is particularly important for the display of dynamic images, such as sports events, action movies, etc. Watching these contents on a small-pitch LED display, you will feel that the picture is more coherent, not blurry, and the colors are more vivid and realistic.
1.3). Other features:
- Seamless:
The unit modules of the small-pitch LED display are spliced very tightly, and there is almost no gap. This makes the entire display look like a whole large screen, providing a more unified and coherent visual experience.
- Ultra-thin and light:
Today’s LED displays are getting thinner and lighter. Small-pitch LED displays are no exception. Its screen body is very thin and light, which makes installation and transportation more convenient.
- التصميم المعياري:
The small-pitch LED display adopts a modular design, which means it can be easily installed, disassembled and repaired. If a module fails, only that module needs to be replaced, not the entire display.
- واسع زاوية الرؤية:
The viewing angle of the small-pitch LED display is very wide. No matter from which angle you look at it, the picture remains clear, and the colour is consistent. This makes it more suitable for occasions where multiple people need to watch at the same time, such as conference rooms, classrooms, etc.
2. Analysis of the demand for small-pitch LED displays in the command and dispatch centre
1). Complexity and diversity of signal display
The command and dispatch centre is really a base camp for information gathering. Various signals come and go every day, and it is very lively. Video signals, digital signals, image signals, everything, and each signal has its own “little temper”.
The video signal must be real-time and smooth, and it cannot be stuck; the digital signal must be accurate, and the numbers and punctuation must not be wrong.
The image signal must process multiple complex pictures at the same time, such as geographic information maps and meteorological cloud maps, and it must be switched quickly.
The small-pitch LED display is quite powerful, with extremely high resolution and clear details. Even in dim light, it can display the picture in a clear layer, and the colours are particularly full.
In this way, the people in charge of command and dispatch can understand it at a glance, and it will be much easier to work.
2). Stability and reliability of all-weather uninterrupted operation
The command and dispatch centre is open 24 hours a day, and the display screen must be on standby at any time. Sometimes when it gets busy, it is working non-stop for several days, and the display screen must be able to withstand it.
Moreover, when there is an emergency, the display screen has to process a lot of information, and it needs to be strong.
Small-pitch LED display screens are quite stable. They use good components and have strict quality control, so they can run stably for a long time and are not prone to problems.
In addition, it is easy to maintain. If any part is broken, just replace it, without replacing the whole unit, which saves money and time.
3). Flexibility and adaptability of emergency command
Sometimes, the command and dispatch centre has to be set up temporarily to deal with emergencies. At this time, the display screen must be flexible and cannot lag behind.
For example, when going to high-altitude areas, the air is thin, the temperature is low, and the display screen must be able to adapt.
When going to the wild, the weather is changeable, and the environment is harsh, and the display screen must be able to withstand the toss.
Small-pitch LED display is quite flexible, designed to be thin and light, and easy to transport and install. Modular design: you can install it however you want and dismantle it however you want.
Moreover, it has good heat dissipation, is not afraid of high or low temperatures, is waterproof and dustproof, and can cope with outdoor environments.
In this way, the command and dispatch personnel can set it up anytime and anywhere to deal with various emergencies.
3. What are the application advantages of small-pitch LED displays in the command and dispatch centre?
1). Seamless splicing and consistent picture
A big trick of small-pitch LED display is seamless splicing, which is really a blessing for the command and dispatch center! You know, the sense of fragmentation of the picture caused by the seams between units is a headache.
But small-pitch LED display is different. Through ultra-precision manufacturing technology, it makes it almost impossible to see the seams between units, and the integrity and continuity of the picture are super good, just like watching a completely large screen.
علاوة على ذلك، سطوع consistency is also a highlight of small-pitch LED display. Just think about it, if the screen is bright in one part and dark in another, it will look so awkward.
However, the small-pitch LED display screen uses advanced technical means, such as color calibration system and brightness adjustment algorithm, to ensure that the brightness of each unit is exactly the same, and the picture quality is excellent!
2). Rich information content display and interactivity
The small-pitch LED display screen also has a unique skill, which is that it can display multiple videos and images at the same time. This is very practical for the command and dispatch centre!
Whether it is a monitoring screen, conference video, data report, or map information, it can be displayed all at once to meet the diverse display needs.
What’s more amazing is that the small-pitch LED display screen can also collect, store, manage and present various real-time large-format picture information on the large screen, such as geographic information, road network line maps, weather cloud maps, panoramic video, etc.
In this way, the command and dispatch personnel can grasp the latest situation at any time and make accurate decisions.
Moreover, the small-pitch LED display screen also pays special attention to interactivity. Just think about it, if the screen is only one-way display, how boring it would be.
But the small-pitch LED display screen supports touch screen technology, gesture recognition technology, etc., allowing command and dispatch personnel to operate directly on the screen, with super interactivity and much more convenient operation!
3). Development trend of intelligence and networking
Speaking of the future, the application of small-pitch LED display screens in command and control rooms is becoming more and more intelligent, digital, and networked.
Think about it, if the screen can be deeply integrated with the real-time information of the traffic network, the headquarters can centrally control and display, and the efficiency of traffic management will definitely be greatly improved!
For example, in the traffic command and dispatch centre, the small-pitch LED smart display screen can be seamlessly connected with the traffic signal system, monitoring system, etc., and display road conditions, vehicle flow, traffic accidents and other situations in real-time.
In this way, the command and dispatch personnel can respond quickly, adjust traffic signals, dispatch rescue forces, etc.
Moreover, the development potential of small-pitch LED display screens in intelligence and networking is still great! For example, combined with AI technology, intelligent identification and intelligent analysis can be realized.
Combined with big data technology, the laws behind traffic data can be mined; combined with cloud computing technology, remote control and cloud storage can be realized.
In short, the application prospects of small-pitch LED display screens in command and dispatch centres are infinitely broad!
4. Why don't other LED display screens replace small-pitch LED display screens in command and dispatch centres?
Why do other LED displays not replace small-pitch LED displays in the command and dispatch centre? In fact, the reason is quite simple. The main reason is that small-pitch LED displays have too many advantages that other LED displays cannot match.
First of all, look at the picture. The small-pitch LED display is almost seamless. The whole picture looks very complete and coherent. It looks very comfortable when commanding and dispatching, and it will not be intermittent because of the seams.
Other LED displays have large gaps when they are put together, which makes them not so pleasing to the eye.
Let’s talk about the picture quality. The pixels of small-pitch LED displays are very dense, the resolution is super high, and the picture looks very clear and delicate.
The command and dispatch centre has so much information to see; how can the picture quality be bad? Other LED displays have less dense pixels, and the picture quality is far worse.
There are also brightness and contrast. Sometimes, the light in the command and dispatch centre is very bright, and the screen must be bright enough.
Small-pitch LED displays have high brightness and strong contrast, and the picture is clear even under strong light. Other LED displays may not be clear under strong light.
In terms of flexibility, small-pitch LED displays can be assembled in any way you want, and the size and shape can be changed, which is particularly suitable for the changing needs of the command and dispatch centre. Other LED displays are not so flexible.
Stability is also very important, and the command and dispatch centre cannot fail. Small-pitch LED displays are reliable and can operate stably for a long time. Other LED displays may not be so stable and prone to problems.
Finally, command and dispatch centers are becoming more and more intelligent and networked. Small-pitch LED displays have also kept up with this trend and can be connected to various smart devices, which is very convenient to operate. Other LED displays may not be so smart.
So you see, small-pitch LED displays have so many advantages, how can other LED displays compare? In the command and dispatch center, of course, small-pitch LED displays are still selected!
