Notch filters (BEF, band inhibition) can transmission most wavelengths, but attenuates light to very low levels in a specific wavelength range (BEF). Notch filters, in contrast to band-pass filters, only inhibit light in a narrower wavelength range.

Usually, the LCD splicing device has two conditions. One is a protective layer on the outside of the LCD, such as a transparent hard plastic, so that our fingers and dust do not actually touch the LCD itself. Only need to pay attention to the appearance of cleaning will be satisfied; the second and most common is the direct exposure of the LCD screen, any external substances can simply touch the surface of the LCD screen, then, when we clean the LCD screen protection, it must Be more careful.
Myth #1: Clean the LCD screen with alcohol and other chemical solvents. Usually, alcohol is a commonly used organic solvent that can dissolve some dirt that is not easily wiped off, but do not use alcohol to clean the LCD splicing screen once alcohol is used. Scrubbing the splicing screen will dissolve the special coating applied by the manufacturer on the LCD splicing screen, which will have an adverse effect on the display function.
Misunderstanding 2: Cleaning LCD splicing screen Applying clear water, the liquid can easily enter the LCD screen, which can easily cause a short circuit in the splicing screen device circuit and burn out the entire LCD splicing wall. Moreover, with regard to fingerprints and oil stains, the cleansing of water is not sufficient in the end, and in more situations, the more the flowers are wiped.
Misunderstanding 3: Use a soft cloth, eyeglass cloth, or paper towel to scrub the LCD screen. It is usually very easy to scratch the “squeegee†LCD splicing screen. With respect to dust, we can blow it out by blowing it first. The remaining dust particles are scrubbed gently on the surface of the splicing screen using a dedicated LCD scrubbing cloth. In general, fingerprints and oil stains are not as simple as the former, and special liquid crystal scrubbing cloths can be used. This is easier to clean. Because the special liquid crystal scrubbing cloth uses special fibers, it has much better scrubbing than the usual advanced eyeglasses cloth. Function, and soft will not scratch the screen, but also has the function of dissipating static electricity, to avoid further adsorption of dust.
Be careful about the three errors of LCD splicing screen to shorten its life span
With the continuous progress of LCD splicing technology, the application fields of LCD splicing screens have now spanned industries such as entertainment, security, broadcasting, and advertising; in our lives, you can see the splicing of LCD panels everywhere; along with the splicing of liquid crystals. Popularity The maintenance of LCD splicing screens in daily life therefore plays an important role in extending the service life of LCD splicing screens.
