What is Nano Coating?
Nano coating is a thin, transparent protective layer made using nanotechnology—the manipulation of matter at the molecular or atomic level (typically 1–100 nanometers). It is designed to bond to surfaces and provide enhanced properties such as water repellency (hydrophobicity), scratch resistance, UV protection, anti-corrosion, and self-cleaning.
Introducation:
Nano-coating is a process where a very thin layer (typically less than 100 nanometers) of material is applied to a surface to enhance its properties. These coatings, often made from materials like silica or titanium dioxide, offer benefits such as water and oil repellence, anti-corrosion protection, and enhanced scratch resistance. 
Nano Coating is a transparent, ultra-thin protective layer applied at the nanometer level. In the context of indoor LED screens, it’s used to:
(1)    Protect against dust, moisture, fingerprints, and UV damage
(2)    Provide a hydrophobic (water-repelling) and oleophobic (oil-repelling) surface
(3)    Maintain screen clarity and brightness without affecting resolution
(4)    Reduce maintenance and cleaning needs
GOB (Glue on Board):
GOB is a newer LED display protection technology where a clear epoxy resin is poured over the entire module surface, encapsulating the LEDs. It provides:
(1)    Complete physical protection for LEDs
(2)    High moisture, dust, and impact resistance
(3)    Better durability in demanding indoor environments
(4)    Slight trade-off in heat dissipation compared to open designs
