Polarizer Film
Polarizer film, also known as Polarizer, polarizer is divided into upper polarizer and lower polarizer. The polarizing functions of the upper and lower polarizers are perpendicular to each other, and their function is like a fence, blocking light wave components according to requirements, such as blocking out the polarizers perpendicular to the fence. Only the light wave components parallel to the fence are allowed to pass through.

Glass Substrate
Glass substrate can be divided into an upper substrate and a lower substrate in a liquid crystal display, and its main function is to clamp the liquid crystal material in the space between the two substrates. The material of the glass substrate is generally alkali-free borosilicate glass with excellent mechanical properties, heat resistance and chemical corrosion resistance.

Black Matrix
Black matrix uses materials with high shading properties to separate the three primary colors of red, green and blue in the color filter (to prevent color confusion) and prevent light leakage, thereby helping to improve the contrast of each color block.

Color Filter
Color filter, also known as color filter film, is used to generate three primary colors of red, green and blue light to achieve full-color display of liquid crystal displays.

Alignment Layer
Alignment layer, also known as alignment film or alignment layer, is used to enable liquid crystal molecules to achieve uniform alignment and orientation at the microscopic level.

Transparent Electrode
The transparent electrode is divided into a common electrode and a pixel electrode, and the input signal voltage is loaded between the two electrodes of the pixel electrode and the common electrode. The transparent electrode is usually formed by depositing an indium tin oxide (ITO) material on a glass substrate to form a transparent conductive layer.

Liquid Crystal Material
Liquid crystal material acts like a light valve in LCD, which can control the brightness and darkness of transmitted light, to achieve the effect of information display.

Driver IC
The driver IC is actually a set of integrated circuit chip devices, which is used to adjust and control the phase, peak value, frequency, etc. of the potential signal on the transparent electrode, establish the driving electric field, and finally realize the information display of the liquid crystal.

Liquid Crystal Panel
In the liquid crystal panel, the active matrix liquid crystal display screen is composed of a twisted nematic (TN) type liquid crystal material enclosed between two glass substrates. Wherein, the upper glass substrate close to the display screen is deposited with red, green and blue (RGB) color filters (or color filters), a black matrix and a common transparent electrode. The lower glass substrate (the substrate farther from the display screen) is installed with thin film transistor (TFT) devices, transparent pixel electrodes, storage capacitors, gate lines, signal lines, and the like. An alignment film (or an alignment layer) is prepared on the inner side of the two glass substrates to align the liquid crystal molecules. Liquid crystal material is poured between the two glass substrates, and spacers are distributed to ensure the uniformity of the gap.

Disconnect the Power
No matter what type of small pitch LED displays you are cleaning, the first step is to shut down the system and disconnect the power supply, then wait a few minutes for it to cool down. It will reduce the risk of electrocution and make it easier to clean the small pitch LED display without creating annoying and unsightly streaks.

Clean with Microfiber Cloth
The screen of a small pitch LED display is an important medium for achieving high quality image display. Using rough cloth or trying to cut dirt with nails and other tools can easily cause serious damage to the top layer or anti-gloss coating. Therefore, it is wise to use microfiber cloth rather than rough cloth to clean small pitch LED displays. Microfiber cloth is a delicate and soft material, but strong enough to thoroughly clean your small pitch LED displays without causing damage. Moreover, microfiber cloths will not collect or spread lint on your small pitch LED display, and are able to trap large amounts of dirt and dust without leaving streaks because of the intricate way tiny fibers are interwoven.

Use Non-Abrasive Cleaning Solutions
The best way to clean small pitch LED displays is to use non-abrasive cleaning solutions, such as isopropyl alcohol diluted with pure or distilled water. Spray the solution onto a microfiber cloth and gently wipe the small pitch LED display by moving it up and down or side to side. Never clean small pitch LED displays with ammonia or alcohol-based cleaners. Ammonia and topical alcohol have the potential to cause irreversible damage to the extremely delicate anti-glare coating. Not only will this negatively impact your viewing experience, it will also make your small pitch LED displays difficult to use in strong sunlight.

Do Not Spray Liquid Cleaners Directly onto the Screen
Spraying liquid cleaners directly on the screen can easily corrode the small pitch LED display due to harsh chemicals. Besides, it is simple for liquid entering the interior to damage the internal components. A safer and smarter way to clean small pitch LED displays is to first wipe it with a dry cloth, then spray a small amount of cleaning solution onto another cloth and gently wipe the surface of the small pitch LED display. Wipe with a clean, dry cloth after this step to remove any residual liquid.

Vacuuming With a Vacuum Cleaner and Compressed Voids
Dust that accumulates between the seams of the small pitch LED display (where the bezel and top glass or plastic meet) may penetrate deeper and cause internal damage to your small pitch LED display. Regular use of a vacuum cleaner with a soft bristle brush can help you keep your devices clean. As an added measure, spray the surface of your small pitch LED displays with a can of compressed air, or even the vents on the back of the unit, to blow away any lingering stubborn debris or dust. The longevity and functionality of your small pitch LED display will ultimately be improved by regularly using this cleaning technique.

Have a Professional Cleaning Team
For outdoor small pitch LED displays installed on building facades, a professional cleaning team is required. To avoid damaging the small pitch LED display, they typically employ aerial ropes or crane boats that are outfitted with expert cleaning equipment, depending on the varied degrees of dirt.
