序章
Educational institutions are constantly exploring how to improve teaching quality and attractiveness through innovative technologies.
As an efficient and interactive display tool, LEDスクリーン have gradually become the first choice of many educational institutions.
But are all educational institutions suitable for installing LED screens? What unexpected changes can it bring to education?
目次
1. Why do educational institutions like to install LED screens?
Training institutions install LED screens mainly to attract people. Now, when people pass by a place, if they can see a bright and moving screen, it will definitely be more eye-catching than a dry poster.
For example, some institutions have LED screens at the door, showing some children’s happy appearance in class, or a particularly exciting clip of the teacher’s lecture.
Parents may go in to ask about the situation when they see it with their children.
Moreover, this kind of screen can also make the institution look more “material”, professional, and powerful, and make people feel that the institution is reliable and trustworthy.
LED screens are very useful in training institutions. In the classroom, teachers can use it to play teaching videos, such as foreign cartoons, when learning English. Children will enjoy watching and learn quickly.
In the hall or corridor, it can always broadcast the course introduction of the institution, the style of the teachers, and the praise of previous students.
In this way, new parents and students can quickly understand what courses the institution has, what the teachers are like, and how previous students learned, which is very helpful for registration.
If the institution has activities, such as open classes, competitions, etc., the activity information can be broadcast on the screen in advance, and the publicity effect is also quite good.
With the LED display, it is much more convenient to update information. In the past, posters and flyers had to be replaced after a while, which was time-consuming and laborious.
Now, if you want to change the content, just move your fingers, and you can change it whenever you want, which is very flexible.
Moreover, it can also centralize the good resources of the institution, such as saving excellent teaching videos and courseware.
When teachers and students need to use them, they can play them directly on the screen without having to look for information everywhere, which is much more worry-free.
In training institutions, LED screens can be seen everywhere, on which students’ excellent homework and work are displayed, as well as the deeds of students who study very hard and have excellent grades.
When other students see these, they will definitely think in their hearts: “I have to work hard and strive to be on the screen.”
In this way, the learning atmosphere is up. Moreover, the screen will also broadcast some learning methods, inspirational stories, etc.
Students can watch them during their breaks and maybe learn something and become more enthusiastic about learning.
2. Considerations for installing LED screens in educational institutions
1). Spatial conditions
The size, shape and height of the space of the educational institution determine the size and installation location of the LED screen.
If the space is too small, installing a large screen will not only appear inconsistent, but may also block the line of sight; if the space is too large and the screen is too small, people behind will not be able to see clearly.
1.1). Small classrooms:
Small classrooms are generally about 30-50 square meters in area and 3-3.5 meters in height. In such places, installing a screen with an area of 0.5 square meters to 1 square meter is enough.
For example, a small classroom of 40 square meters can be equipped with a 0.8 square meter screen, so that students can see clearly no matter where they sit.
It is best to install the LED screen on the wall in front of the classroom, with a height similar to the students’ line of sight, so that everyone can see it comfortably.
1.2). Large auditorium:
A large auditorium may have an area of several hundred square meters and a height of more than 5 meters. In such a place, the screen must be larger, such as 3 square meters or even larger, so that people in the back row can also see it clearly.
The LED screen is generally installed in the center behind the stage, and the height must ensure that the line of sight of the audience in the back row will not be blocked by the audience in the front row.
If conditions permit, auxiliary screens can also be installed on the walls on both sides, so that the visual effect will be better.
2). Budget constraints
The purchase, installation and maintenance of LED display screens all cost money. The budgets of educational institutions of different sizes are definitely different.
So within the limited budget, you have to make a reasonable choice.
Small institutions have limited budgets and may only be able to buy a small screen. It doesn’t matter if the 解決 is a little low, as long as it can be used.
Large institutions or chain institutions with sufficient budgets can buy large screens with high resolution, or even buy more. In short, you need to find the most cost-effective product within a limited budget.
3). Frequency of use
The daily teaching and activity arrangements of educational institutions determine the frequency of use of LED display screens.
If it is used frequently, the screen quality must be higher; if it is used less, it is okay to buy a medium-quality one.
3.1). Daily teaching:
If the institution has many classes every day and the display screen is used in every class, the frequency of use of the screen is very high.
For example, a language training institution has eight classes a day, and each class uses the screen to play videos or courseware, so the screen is used 6-8 hours a day.
In this case, buy a good-quality and high-resolution screen to ensure the teaching effect.
3.2). Activity arrangements:
In addition to daily teaching, the institution will also hold open classes, lectures, competitions and other activities. These activities also require display screens.
For example, an open class is held once a month, and the screen is used for 3-4 hours each time.
Although it is not used much in daily teaching, you have to buy a suitable screen for activities.
By properly arranging courses and activities, the screen usage time can reach a reasonable balance.
3. What precautions should be taken when installing LED display screens in educational institutions?
1). Safety is very important
When installing LED display screens, safety is the top priority. First of all, you must turn off the power first during installation and maintenance.
Never operate with power on, otherwise it is easy to get an electric shock, which is too dangerous.
In addition, the display screen must be grounded, and the grounding resistance must be less than 4Ω, so as to prevent static electricity from damaging the chip inside.
If it encounters a lightning strike, it can also guide the current away to protect the equipment.
If it is installed outdoors, a lightning protection device must be installed to prevent problems during thunderstorms.
Waterproofing is also critical. The place where the display screen and the building are combined must be tight, and water must not be allowed to enter.
There must also be a drainage port, otherwise water will accumulate inside and the screen will be easily damaged.
2). Don’t ignore heat dissipation and maintenance
LED display screens will heat up when used. If the heat dissipation is not done well, the life of the screen will be greatly reduced.
There must be some space between the modules, at least 10cm, so that air can circulate and heat dissipation is good.
If the screen is large, you may need to install a fan or other ventilation equipment to ensure that the temperature inside is not too high. Generally, it is best to keep it between -10℃ and 40℃.
There should also be enough maintenance space, at least 60cm at the back, for easy repair in the future.
If the screen is designed for front maintenance, the module is installed with magnetic suction, which is convenient for disassembly, and the maintenance efficiency is high.
Regularly clean the dust on the screen, check whether the circuit is loose, and replace the broken parts in time to ensure that the screen always works normally.
3). Pay attention to installation details
When installing the LED display, some details cannot be sloppy. According to the size and use of the screen, choose a suitable location to ensure that everyone can see it and it will not be blocked by other things.
The power cord and signal cable should be of good quality, and they must be firmly connected.
After the connection is completed, they must be debugged to see if the parameters such as 輝度, color, and refresh rate are normal.
In addition, the screen must be installed firmly, whether it is hung on the wall, on a bracket or in other ways, it cannot shake, otherwise the screen will easily break.
4. Future demand trends for LED displays in educational institutions
1). New opportunities brought by technological upgrades
In the future, the technology of LED displays will become more and more powerful. First of all, the 解決 will be higher and higher, and the pictures on the screen will be clearer and clearer.
Future LED displays can also display ultra-high-definition images. For example, in medical education, every detail of the human anatomy can be clearly seen.
In art education, high-definition works of art can be displayed, allowing students to see clearly.
In addition, LED displays will become smarter. It can not only display content, but also automatically adjust the brightness according to the ambient light, and automatically push relevant materials according to the teaching content.
For example, in a smart classroom, the display can be connected to the teaching management system to provide real-time feedback on students’ learning progress and provide teachers with personalized teaching suggestions.
In this way, teachers can teach more accurately and students can learn better.
2). The impact of changes in education models
Now, the education model is also changing, and online and offline integrated teaching, virtual reality (VR) and augmented reality (AR) teaching are becoming more and more popular.
These new education models have put forward new requirements for LED displays, but also brought it more opportunities.
For example, online and offline integrated teaching requires LED displays to support high-definition video conferencing, so that online students can clearly see the teacher and teaching content.
At the same time, the screen is preferably touch-sensitive, so that teachers and students can directly mark and write on it to increase interactivity.
For another example, VR and AR teaching require ultra-high-definition displays to provide an immersive experience.
In the future, LED displays may be used on VR and AR devices, allowing students to experience ancient civilizations in history classes and to intuitively see the three-dimensional model of the Earth in geography classes.
This immersive teaching can not only stimulate students’ interest in learning but also enable them to better understand and remember knowledge.
In short, the technological upgrade of LED displays and the transformation of educational models complement each other.
Educational institutions should pay attention to these trends and reasonably configure LED displays to meet the diverse needs of future teaching, making teaching more efficient and interesting.
5。結論
From attracting attention to assisting teaching, from improving learning motivation to optimizing management efficiency, LED displays have brought all-round changes to educational institutions.
However, the selection and application of technology is not static. With the continuous innovation of education models in the future, how will LED displays adapt to new needs? It is worth our continued attention.
