We all know that dust can be harmful to the human body, but you probably didn't expect it to be the same for LCD splicing screens. Today, the editor will give us an overview of how much dust can damage LCD splicing walls. Just as fog can cause serious damage to the human body, dust similar to fog is also the archenemy of electronic products. LCD splicing, as a highly technological electronic product, is greatly affected by dust. The LCD splicing screen movement uses many optical components, and dust causes the greatest damage to the optical components.

Dust causes 4 direct damages to LCD splicing walls

Decreased contrast

The definition of contrast is the maximum brightness value that the large screen display unit can output divided by the darkest brightness value. When in a dark scene, dust on the optical component will reflect stray light, projecting light that should not be projected from the lens and adding brightness to the dark areas. Some light in bright areas may be obstructed by dust, reducing the reflection and transmission of light and decreasing the brightness value of the bright areas. This naturally leads to a decrease in contrast.

Color wheel speed decreases

The color wheel of LCD splicing screen is the main accessory for processing colors, which includes a high-speed motor with a speed of about 7200 revolutions per minute. If a lot of dust adheres around the color wheel, it will affect the rolling of the color wheel, causing a decrease or instability in the speed of the color wheel and presenting problems.

Screen brightness decreases

The brightness of LCD splicing screens is output through reflective lenses and lenses. If dust accumulates on the surface of optical components, the reflectivity and transmittance decrease over time, resulting in a decrease in brightness.

Causing the picture to appear blurry

When dust accumulates to a certain extent on the optical components inside the LCD splicing screen, it will alter the path of light, causing the light to not converge on the same focal point, resulting in blurry images on the screen. We usually think that dust only affects the appearance of LCD screens, but we don't know that it has such a significant impact on the functionality of LCD screens. In daily life, we must pay attention to dust prevention to extend the service life of products.

4 major maintenance methods for LCD splicing walls

Avoid strong impact

Because LCD splicing screens contain many precision glass and electrical components, LCD splicing screens are very delicate and have poor impact resistance. Once subjected to strong impact, it will cause damage to the LCD splicing screen and other related components. Additionally, do not apply pressure to the surface of the LCD splicing screen, such as pointing fingers at a specific part of the screen.

Maintain a dry usage environment

This is an important condition for the normal operation of LCD splicing screens. The internal design of LCD splicing screens is very precise, and if used in a humid environment, it is prone to oxidation, corrosion, short circuits, and other phenomena, causing huge economic losses to users. Therefore, it is necessary to maintain a dry usage environment for LCD splicing screens as much as possible. If moisture is found on the surface of the screen, gently wipe it off with a soft cloth before turning on the power to work. If moisture has entered the LCD splicing screen, it must be placed in a well ventilated or warm place to allow the moisture to evaporate. If the situation is more severe, ordinary users can seek professional assistance to solve it. Never power on the LCD splicing screen without removing moisture, otherwise it will cause corrosion of the LCD electrodes and permanent damage to the LCD splicing screen.

Correctly clean the LCD splicing screen

LCD splicing screens are prone to dust and dirt after prolonged use, and cleaning the LCD splicing screen is inevitable. When cleaning, we should use the correct cleaning method: use a soft, non fiber material such as degreasing cotton, lens paper, or soft cloth dipped in a small amount of glass cleaner to gently wipe off the dust or dirt on the screen.

When cleaning, it is prohibited to use organic chemical solvents such as alcohol, and rough cloth or paper items should not be used, as these substances can easily cause scratches and affect the display effect. Also, be careful not to spray the cleaning agent directly onto the surface of the display screen, as it can easily flow into the screen and cause a short circuit fault inside the LCD splicing screen, resulting in unnecessary losses.

Pay attention to usage time and avoid working for long periods of time

Long term overloaded work can easily cause certain pixels of the LCD splicing screen to overheat, and exceeding the limit can lead to permanent damage. The pixels of the LCD splicing screen are composed of liquid crystals. When it works continuously at full load for more than 95 hours, it will accelerate the aging process of the LCD splicing screen, and more seriously, it will burn out. Therefore, users should pay attention to the usage time and avoid working for a long time when using LCD splicing screens. This not only extends the service life of the LCD screen, delays the aging process, but also avoids hardware damage.
