At present, the LCD splicing screen in the indoor high-end command and control center, dispatch center, monitoring center and other application industries are developing more and more mature. We all know that dust has damage to the human body, but you certainly did not expect dust on the LCD splicing screen is also the same. LCD splicing as a very high technology content of electronic goods, dust also caused a great impact on it. LCD splicing screen movement using a lot of optical components, precisely dust on the optical components of the greatest damage, the following SINDA Display to explain in detail.

Contrast refers to the large screen unit can output the maximum luminance value divided by the darkest luminance value, when the dust on the optical components in the dark scene will reflect stray light, the light should not be projected from the lens to project out, adding the dark part of the brightness. The same in the bright part when some light will be dust obstruction, reduce the amount of light reflection and transmission, and drop the brightness value of the bright part, which is a natural contrast drop.

LCD splicing screen color wheel is the main accessory to deal with color, which has a high-speed motor, about 7200 revolutions per minute. If a lot of dust attached to the color wheel around, it will affect the color wheel rolling, the formation of color wheel speed decline or instability.

The brightness of the LCD splicing screen is through the reflective lens and lens output brightness, if the dust accumulates in the optical component appearance, the reflectivity and transmittance decreases with time to form the brightness decline.

When the dust in the LCD splicing screen internal optical components on the accumulation to a certain extent, it will change the path of light, resulting in the collection of light collection can not collect in the same focus above, so it will make the screen image becomes blurred. Usually we think that dust is only affect the appearance of the LCD screen, but do not know that the LCD screen function also has such a great impact, in daily life, we must pay attention to dust, in order to extend the service life of goods.
