¿Qué tipo de pantalla LED es adecuada para las bibliotecas?

1). Information display requirements

The library has a lot of information and updates quickly, so LED display screens come in handy. After the traditional banner in front of the gate is replaced with an LED screen, event information, opening hours, and special notices can be displayed in real-time.

The content is diverse and fresh, and the library looks more fashionable. The large screen in the lobby loops the entrance instructions, collection guide, and the latest notices, which readers can see as soon as they enter the door, which is convenient and fast.

The guide screen in the reading room is even more practical. The collection location and temporary notices are clear at a glance, which makes it much faster to find books and materials.

2). Environmental adaptability requirements

The environment in the library is special, and the brillo, temperature, and humidity must be considered when choosing an LED display screen. The screen cannot be too bright or dazzling. You have to choose a screen that is comfortable to look at and friendly to the eyes.

The temperature and humidity in the library are stable, but you have to choose a screen that can adapt to some changes. After all, it will be used for a long time. In addition, the screen design must match the style of the library and not make it too abrupt, which will destroy the reading atmosphere.

3). Maintenance and management requirements

When managing LED display screens, libraries need to consider whether maintenance and management are convenient. The screen should be easy to install and adjust and easy to repair if there is a problem so that the management cost is low.

It is best to be able to control it remotely, and content updates and mode adjustments can be made online so that there is no need to run to the site all the time, and management efficiency is also improved.

Therefore, when choosing LED display screens, libraries must consider these aspects comprehensively and find a solution that suits them.

1). Installation process

Installing an LED display screen in a library is actually like completing a fine handicraft, which requires patience and carefulness, step by step:

1.1). Site survey:

First, you have to take a look around the library to see which location is most suitable for installing the LED display screen.

The foyer is a good choice, which is conspicuous and convenient; the entrance to the reading room is also good, and readers can see it as soon as they enter the door; the wall is also fine, as long as it does not affect reading and walking.

After determining the location, you have to measure how long the signal line should be. From the display screen to the control room, or to the network access point, all must be measured accurately so that the appropriate cable can be selected.

1.2). Design and wiring:

After selecting the cables, you have to plan how to route them. The cables must be neatly laid out, not tangled like a spider web. You can run them along the corners of the wall or hide them in the ceiling, but you have to make sure that people can’t see them.

The cables must also be protected so that people don’t trip over them or rats bite them. You can use cable troughs or cable tubes to protect the cables, which is both beautiful and safe.

1.3). Install the screen:

First, install the frame firmly, and use expansion screws or other fixings to firmly fix the frame to the wall or the ground. The frame must be installed horizontally, not crooked.

Then, put the LED screen together piece by piece, like a puzzle. When putting it together, pay attention to alignment and leave no gaps. After connecting the power supply and control lines, check whether there are any wrong or loose connections.

Finally, turn on the power to see if the screen is bright and the color is correct. If there is a problem, you need to adjust or replace it in time.

1.4). Debug the system:

The power supply system must be adjusted steadily, and it should not be bright and dark at the same time. You can use a multimeter to measure the voltage and current to ensure that they are within the normal range.

The display system must also be adjusted, and the words and pictures must be clear. You can play some test pictures or texts to see the display effect.

The network system must also be unobstructed, and remote control and content updates depend on it. You can try to change the content on the display through remote control.

2). Maintenance

After installation, you still have to take care of it regularly, just like treating your own baby:

2.1). Regular inspection:

Every once in a while, you have to check whether the screen is still bright and whether there are dark spots or bright spots. The colors are uneven. Is there any color cast or discoloration? Is the picture clear? Is there any blur or jitter?

Check the frame and wires to see if they are loose, broken, or aged. In particular, check the frame fixings to see if they are loose or falling off.

Check the power supply and control system to see if they are normal. You can use a multimeter to measure the output voltage and current of the power supply to see if they are within the normal range. You should also try to see if the control system can work normally, such as whether it can receive remote commands, whether it can change the display content, etc.

2.2). Cleaning and maintenance:

The screen needs to be wiped regularly with a soft cloth dipped in water, not too wet. Wipe gently when wiping; don’t rub hard to avoid scratching the surface of the screen.

If there are stubborn stains or dust on the screen, you can use a special cleaner to clean it, but be careful not to let the cleaner flow into the screen.

Especially for outdoor screens or screens near doors and windows, there is a lot of dust, so you need to be more diligent. You can wipe it once a day or a week to keep the screen clean and tidy.

In addition to the screen surface, the heat sink or fan behind the screen should also be cleaned to prevent dust accumulation from affecting the heat dissipation effect.

2.3). Troubleshooting:

If there is a problem with the screen, such as a flowery screen, wrong color, black screen, etc., you have to deal with it quickly. First, you have to see if it is a problem with the power supply or control system. You can try to change the power supply or restart the control system to see if the problem can be solved.

If it is not a problem with the power supply or control system, then you have to see if it is a problem with the screen itself. You can check whether the connection cable of the screen is loose or broken, or check whether the module on the screen is damaged or aged.

If you can’t do it yourself, you have to find a professional to repair it. You can contact the manufacturer or maintenance service provider of the display screen and ask them to help with inspection and repair. Don’t think about it or dismantle and repair it randomly so as not to make the problem bigger.

In addition, in order to make the LED display screen last longer in the library, you have to pay attention to a few points:

• Don’t always turn on the display screen without playing content or playing all-white and all-bright content, which will easily make the LED tube age faster. You can set some timer switches or brightness adjustment functions to extend the service life of the display screen.

• The environment should be dry and ventilated, not too humid or too hot. If the environment is too humid or too hot, it will easily affect the normal operation and service life of the display. You can install some dehumidifiers or air conditioners to adjust the humidity and temperature of the environment.

• Electromagnetic radiation should also be kept away. If there are some devices or devices with strong electromagnetic radiation near the display, it is easy to interfere with the normal operation of the display. You can try to move these devices or devices away or take some shielding measures to reduce the interference of electromagnetic radiation.

• Library staff also need to learn how to use and repair the display. In this way, they can solve problems by themselves without always looking for professionals to repair them. Some training or learning activities can be organized to improve the skills and level of staff.
