LCD video walls are often used in indoor high-end command and dispatch centers, dispatch centers, monitoring centers and other application industries. In order to better use the LCD video wall, regular cleaning is essential. However, many companies are not aware of the impact of dust on the LCD video wall after building it. Today we will mainly introduce the impact of dust on the LCD video wall and how to properly maintain the LCD video wall.
What damage can dust cause to the LCD video wall?
Contrast reduction
Contrast is the maximum brightness value that a large-screen display unit can output divided by the darkest brightness value. When in a dark scene, dust on the optical components will reflect stray light and will not project light from the lens, thereby increasing the brightness of the dark part. 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. So when there is dust on the screen, the contrast will decrease.
Color wheel speed decreases
The color wheel of the LCD video wall is the main accessory for color processing, including a high-speed motor with a rotation speed of about 7200 revolutions per minute. If a large amount of dust adheres to the color wheel, it will affect the rolling of the color wheel, causing the color wheel speed to decrease or become unstable, thus causing problems.
Causes the image to appear blurry
When dust accumulates to a certain extent on the optical components inside the LCD splicing screen, it will change the path of light, causing the light to be unable to focus on the same focus when it is focused, so the image displayed on the screen will become blurred.
Screen brightness decreases
The brightness of the LCD splicing screen is output through reflective lenses and lenses. If dust accumulates on the surface of the optical components, the reflectivity and transmittance will decrease over time, resulting in a decrease in brightness.
Maintenance method of LCD video wall
Avoid strong impact
Because the LCD splicing screen contains many precise glass components 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 components will be damaged. So do not press the screen surface when using the LCD video wall.
Maintain a dry use environment
The internal design of the LCD video wall is very precise. If used in a humid environment, it is easy to oxidize and corrode, causing short circuits and other phenomena, bringing huge economic losses. Therefore, companies should do their best to keep the LCD video wall in a dry environment. If moisture is found on the surface of the screen, wipe it gently with a soft cloth before turning on the power. If moisture enters the LCD splicing screen, the LCD video wall must be placed in a well-ventilated or warm place to evaporate the moisture. If the situation is more serious, you can ask a professional to help solve it. Do not turn on the LCD screen without removing moisture. Otherwise, the LCD monitor electrode will be corroded and the LCD monitor panel will be permanently damaged.
Correct cleaning of LCD screen
LCD splicing screen is easy to generate dust and dirt after long-term use. Cleaning LCD splicing screen is inevitable. When cleaning, the correct cleaning method should be used: use soft non-fiber absorbent cotton, lens paper or soft cloth dipped in a little glass cleaner, and gently wipe off the dust or dirt on the screen.
Conclusion
The harm of dust to LCD screens cannot be ignored. In order to extend the service life and display effect of LCD screens, companies can regularly clean the dust on the screens and take effective dust prevention measures. At the same time, during installation and use, attention should also be paid to choosing a clean and well-ventilated place to reduce the impact of dust on the screen.
