As is well known, dust is harmful to the body, but you never expected that the dust on the splicing screen would be the same. Now, Kangweiye is coming again. The degree of damage to the LCD screen junction wall is equivalent to the serious harm of fog to the human body, and foggy dust is also a major enemy of electronic products. Splicing is a high-tech electronic product that has a huge impact on it. The movement of LCD splicing screens utilizes many optical components.

As is well known, dust is harmful to the body, but you never expected that the dust on the splicing screen would be the same. Now, Kangweiye is coming again. The degree of damage to the LCD screen junction wall is equivalent to the serious harm of fog to the human body, and foggy dust is also a major enemy of electronic products. Splicing is a high-tech electronic product that has a huge impact on it. The movement of LCD splicing screens uses many optical components, and dust can cause significant damage to the optical components. Below, Kangwei Weiye will provide you with a detailed analysis of the direct damage caused by LCD splicing screens, divided into 4 points.

1、 Reduce contrast.

The inverse boundary is a large screen display, in addition to very dark luminosity values, when dust on optical components reflects stray light in a dark scene, it should not project outward light to increase the brightness of the dark area. When certain rays of light are in the same light range, they will be blocked by dust, reducing transparency and reflection, lowering the brightness value of bright areas, and naturally reducing contrast.

2、 Reduce the speed of the color wheel.

The LCD screen splicing color wheel is the main accessory for processing colors, including a high-speed motor with a speed of about 7200 revolutions per minute. Assuming there is a large amount of dust 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, leading to malfunctions.

3、 Reduce screen brightness.

The brightness of the splicing screen is determined by the brightness output of the reflective lens and lens. If dust accumulates on the surface of optical components, their reflectivity and transmittance decrease over time.

4. The display image is unclear.

Because dust acts on the optical components of the splicing screen, it can cause changes in the optical path, making it unable to concentrate on the same focal point, resulting in blurry images. People usually think that dust is just a factor in the appearance of LCD screens, but they don't know how much it affects the function of LCD screens. We must pay attention to dust prevention in our daily lives in order to extend the lifespan of our products.
