How to avoid the damage caused by dust to the LCD splicing screen?

We all know that dust is harmful to the human body, but you certainly did not expect that dust is the same for LCD splicing screens. Today's small version will tell us how much dust is harmful to LCD splicing walls. Just like the haze's severe damage to the human body, the mist-like dust is also the enemy of electronics. As a high-tech electronic product, LCD splicing is also greatly affected by dust. The movement of LCD splicing screens uses many optical components, and dust is the most harmful to optical components.


Dust causes 4 kinds of direct damage to the LCD splicing wall:


Contrast attenuation

Contrast is defined as the maximum brightness value that a large-screen display unit can output divided by the darkest brightness value. In dark scenes, dust on the optics reflects stray light and does not project light from the lens, increasing the brightness of the dark parts. At the same time, some light in the bright part will be blocked by dust, which reduces the reflection and transmission of light and reduces the brightness value of the bright part. Therefore, the contrast naturally decreases.

Color wheel speed drops

The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor with a speed of about 7,200 revolutions per minute. If a large amount of dust adheres to the color wheel, it will affect the color wheel's rolling, causing the speed of the color wheel to decrease or become unstable, thereby causing problems.


Screen brightness drops

The brightness of the LCD splicing screen is output through the reflective lens and lens. If dust accumulates on the outer surface of the optical element, the reflectance and transmittance decrease over time, resulting in a decrease in brightness.


Make the picture look blurry

When a certain amount of dust has accumulated on the optical elements inside the LCD splicing screen, the way of light will change, so that the light cannot be focused on the same focus when collected, thereby making the picture displayed on the screen blurred. Usually we think that dust only affects the appearance of LCD monitors, but we don't know that it has such a large effect on the function of LCD monitors. In daily life, we must pay attention to dust to extend the life of the product.


Four maintenance methods of LCD splicing wall


Avoid strong shocks

Since the LCD splicing screen contains many precision glass and electrical components, the LCD splicing screen is very delicate and has poor impact resistance. Once subjected to a strong impact, the LCD splicing screen and other related parts will be damaged. Also, do not put pressure on the surface of the LCD splicing screen, such as pointing your finger at a part of the screen.


Keep it dry

This is an important condition for the normal operation of the LCD splicing screen. The internal design of the LCD splicing screen is very precise. If it is used in a humid environment, it is easy to oxidize and corrode, causing short circuits and other phenomena, which will bring huge economic losses to users. Therefore, we should do our best to keep the LCD splicing screen in a dry environment. If you find moisture on the screen surface, wipe it gently with a soft cloth before turning on the power. If moisture enters the LCD splicing screen, the LCD splicing screen must be placed in a well-ventilated or warm place to evaporate moisture. If the situation is more serious, ordinary users can ask a professional to help solve it. Do not open the LCD screen without removing moisture. Otherwise, the LCD electrodes will be corroded and the LCD panel will be permanently damaged.


Correct cleaning of the LCD screen

The LCD splicing screen is used for a long time, and it is easy to produce dust and dirt. Cleaning the LCD splicing screen is inevitable. When cleaning, you should use the correct cleaning method: use a soft non-fiber absorbent cotton, lens paper or a soft cloth with a little glass cleaner, and gently wipe off the dust or dirt on the screen.

When cleaning, do not use organic chemical solvents, such as alcohol, coarse cloth or paper products, because these substances are easy to scratch and affect the display effect. Care should also be taken not to spray the cleaning agent directly on the display surface, so that the cleaning agent can easily flow into the display screen, causing an internal short-circuit failure of the LCD splicing screen, causing unnecessary losses.


Pay attention to the use time and avoid working long hours.

Overloading for a long time can easily cause some pixels on the LCD screen to overheat. If it exceeds the limit, it will cause permanent damage. The pixels of the LCD splicing screen are composed of liquid crystal. When the LCD splicing screen works continuously for more than 95 hours at full load, the aging process of the LCD splicing screen will be accelerated and even burned out. Therefore, users should pay attention to the use time when using the LCD splicing screen to avoid working for a long time. This can not only extend the life of the LCD screen, delay the aging process, but also avoid hardware damage.
