LCD splicing screen is often damaged by dust

At present, LCD splicing screens are becoming more and more mature in application industries such as indoor high-end command and control centers, dispatch centers, and monitoring centers. We all know that dust is harmful to the human body, but you certainly did not expect that dust will also do the same to LCD splicing screens. As an electronic product with extremely high technological content, LCD splicing has a great impact on it due to dust. The LCD splicing screen movement uses many optical components, and it is precisely the dust that damages the optical components the most.

Contrast refers to the maximum brightness value that the large screen display unit can output divided by the darkest brightness value. When in a dark scene, the dust on the optical components will reflect stray light and project the light that should not be projected from the lens. The brightness of the dark part. Similarly, some light in the bright part will be blocked by dust, reducing the amount of light reflection and transmission, and reducing the brightness value of the bright part, the contrast will naturally decrease in the past.

The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor, which rotates at about 7200 revolutions per minute. If a lot of dust is attached to the periphery of the color wheel, it will affect the rolling of the color wheel, resulting in a decrease or instability of the color wheel speed, which may cause problems.

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

When dust accumulates on the optical components inside the LCD splicing screen to a certain extent, it will change the light path, so that the light cannot be gathered on the same focal point when it is gathered, so the displayed image on the screen will become blurred. We usually think that dust only affects the appearance of the LCD screen, but we don’t know that it also has such a big impact on the function of the LCD screen. In our daily life, we must pay attention to dust prevention to extend the service life of the product.
