Information

16:9 LED video manufacturers tell you that dust is harmful to the human body, but you certainly did not expect that it is also very harmful to the LCD splicing screen. Today, let’s take a look at the damage caused by dust to the LCD splicing wall. 16:9 LED video manufacturers tell you that dust similar to haze is also a deadly enemy of electronic products. LCD splicing is an electronic product with extremely high technical content, and dust will also have a great impact on it. 16:9 LED video manufacturers tell you that the LCD splicing screen uses a large number of optical components, and it is precisely the dust that causes the most damage to the optical components.

good price and quality 16:9 LED video company
Dust brings 4 direct damages to the LCD splicing wall:
1. Contrast drops
16:9 LED video manufacturer tells you that 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, the dust on the optical components will reflect stray light, which will not The light projected from the lens should be projected to add the brightness of the dark part. 16:9 LED video manufacturer tells you that some light in the bright part will be blocked by dust, reducing the amount of light reflection and transmission, and lowering the brightness value of the bright part, the contrast will naturally drop. .
2. The color wheel speed drops
16:9 LED video manufacturers tell you that 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 will cause problems.
3. The screen brightness drops
16:9 LED video manufacturer tells you that the brightness of the LCD splicing screen is output through the reflective lens and lens. If dust accumulates on the surface of the optical component, the reflectance and transmittance will decrease with time.
4. Make the picture appear vague
16:9 LED video manufacturer tells you that 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 collected on the same focus when it is collected, so it will make the screen The appearance picture above becomes ambiguous. 16:9 LED video manufacturers tell you that we usually think that dust only affects the appearance of the LCD screen, but we don't know that it has such a big impact on the function of the LCD screen. In daily life, we must pay attention to dust prevention to extend Product service life.
