How to prevent dust from damaging the HD LCD TV screen?

Contrast diminishes.

The contrast ratio is defined as the maximum brightness value output by the large screen display unit divided by the dark brightness value. When night falls, the dust on the optics reflects stray light, and the light on the lens doesn't brighten the night. At the same time, part of the light in the bright part will be blocked by dust, so that the reflection and transmission of the light will be reduced, and the brightness of the bright part will be reduced. So the contrast will naturally drop.

Color Wheel Down Speed The color wheel of an HD LCD TV is a staple in color processing and includes a high-speed motor that can spin up to 7,200 rpm. If there is a lot of dust around the color wheel, it will affect the work of the color wheel, and the speed of the color wheel will decrease or become unstable, which will cause problems.

Screen brightness decreases.

The brightness of high-definition LCD TVs is output through mirrors and lenses. If dust collects on the surface of the optical element, the reflectivity and transmittance will gradually decrease over time, resulting in a decrease in brightness.
