How to clean the LED display?

Turn off the power of the LCD and remove the power cord plug and the graphics card cable plug.

Move the LCD to a place with better natural light, so that you can see where the dust is, which is more conducive to targeting, so as to achieve a better cleaning effect.

Cleaning the LCD screen does not require any special solution or cloth, in the author's experience, water + soft lint-free cloth or cotton lint-free cloth is the best LCD screen cleaning tool (no lint paper towel is OK). When cleaning, you can use a cotton lint-free cloth dipped in water and then wring it out slightly, and then use a slightly damp soft lint-free damp cloth to gently wipe the dust on the display screen (do not squeeze the display screen hard), it is recommended to wipe from one side of the display screen to the other until it is all wiped clean, do not wave indiscriminately.

Tip: Do not wipe with a hard cloth or hard paper. At the same time, do not use cleaning liquids containing alcohol or acetone or detergents containing chemical ingredients, and do not spray liquids directly onto the screen to prevent the liquid from penetrating into the protective film.

After cleaning the LCD screen with a damp, soft, damp cloth, you can use a damp cloth that has been wrung dry to clean it again. Finally, let the water vapor on the LCD screen air dry naturally in a ventilated place.

2.Other maintenance points.

1) Avoid vibrations. LCD screens are fragile and need to be protected from strong shocks and vibrations. Do not put pressure on the LCD screen or collide or squeeze on the back cover of the LCD display.

2) Avoid using the screen for a long time. Long-term work is not a good thing for LCDs, and if you don't use it, be sure to power off the display. In the same way, be cautious when using LCD wallpapers and screensavers.

Most of the wallpapers and screensavers have bright colors, and the light and dark changes are strong, and long-term use will distort the LCD color, which will affect the life of the LCD display. So, it's best to use a monochrome screen and remove the screensaver when using LCD.

3) Anti-electromagnetic interference. Whether it is a CRT or LCD display, it is necessary to stay away from objects with strong magnetic fields, as the strong surrounding magnetic field will generate additional voltage inside the display, which will affect the stability of the display voltage. Being in a strong magnetic field for a long time will also distort the color, which will affect the display effect and life of the LCD.

4) Pay attention to moisture. Do not let any moisture enter the LCD, if the indoor humidity is too high, the inside of the LCD may produce condensation, resulting in leakage and short circuit of the LCD, and in serious cases, the display will be burned. For some southern areas with high humidity, the LCD can be placed in a warmer and drier place, or the back of the LCD can be regularly baked with a low-power desk lamp to allow the moisture in it to evaporate.

There is a dedicated LCD screen wipe, or lotion.

Broken screen problem To avoid possible problems, we can choose passive protection and active protection, passive protection means that some Internet cafes, dormitories and other public places users can choose to buy a monitor with tempered glass, which can make your display screen "invulnerable, water and fire invulnerable", but it will affect the color of the display, and there will be reflection; Active protection is to be careful in ordinary use, try to keep items that may cause damage to the screen away from the screen, and wipe as gently as possible when cleaning the screen to minimize the possibility of damage.

Maintain the humidity of the environment All users who have ever caused keyboard damage by spilling a drink on the keyboard know this common sense. Don't let anything with moisture properties get into your LED display. If you find a fog, gently wipe it off with a soft cloth before you can turn it on.

If the moisture has already entered the inside of the display, it is important to place the display in a warm, dry place to allow the moisture and organics to evaporate. Powering an LCD display with humidity can cause corrosion of the LCD electrodes, which can cause permanent damage.

LCD displays are the most closely related to our users, and it is also very necessary to do a good job of cleaning and hygiene. In fact, the LCD display is also particularly easy to be dirty, and the white appearance is indeed good-looking, but if you don't pay attention to maintenance, it will soon become yellowish; The piano paint is indeed very performant, but after a week of use, the shell must be covered with handprints; Even if it is an ordinary black matte material, after a while, the screen must be dusty. So clean it up regularly.

The cost of cleaning liquid generally includes electrolyte, high-purity distilled water, antistatic fluid, etc., which can effectively clean dust, finger prints and other stains on the screen, and you can buy some well-known brand products. The good cleaning cloth is also very particular, it must be a product made of ultra-fine fiber as raw materials, and the glasses cloth sent by high-end glasses can also be used as a cleaning cloth.

How much is a square LED display? For customers who want to buy and install LED displays, ** is a very important factor.

Normally, the LED display screen is squared, and there are three main factors that affect the LED display screen

The size of the display body. The size of the LED display screen is made according to the installation environment and customer needs, and there is no limit to the size.

The dot pitch of the display (specification, model). For example, the point spacing of the LED display in the conference room is commonly P3 and P4, and the following small pitch LED display is also used more and more, while the point spacing of the outdoor LED display is P8, P10 and above. 3.

Raw materials. Different LED lamp beads and shells** are also different.

LED display is actually a system, in addition to the display screen, there are control systems, there are two common kinds, one is Nova, the other is Lingxingyu, supporting systems, such as computers, lightning arresters, audio, distribution boxes, air conditioners, etc. In addition, there is steel structure and installation. These are all related to **.

LED display companies can only provide comprehensive information such as clear LED display area, dot spacing model and installation method.

Taking the LED transparent screen as an example, the first composition of the LED turbine screen includes:

1. Display screen**. This piece accounts for more than 60% of the total price of LED displays. At present, the market is generally 2000-6000 yuan square meters. The transparent LED display screen is composed of a power supply, a box, a cable, a power cord, etc.

2. Control system. This includes sending and receiving cards.

3. Project installation and commissioning. Including the steel structure and production of the screen body, the wiring of power cables and signal cables, and the installation and commissioning of the display screen.

5. Miscellaneous. Including the cost of the flight box or wooden box, as well as the cost of shipping and transportation logistics.

Dust and ventilation are cleaned regularly, and the most common problem with LEDs is poor heat dissipation.

Consider using it indoors and outdoors to check the voltage and current regularly.
