Pro-Tek Protective GOB Coating

Today’s LED displays are used for many applications, many of which are in high-traffic areas like malls, airports and schools, where visitors are often tempted to touch and feel them to experience your content.' LED displays with higher resolutions (more pixels) require smaller LED package sizes to accommodate higher component densities. These packages do not contain plastic material, but are a fiber glass substrate with copper plating that are used to hold the LED diodes, wire bonding, and the lens which makes your high resolution LED panel extremely fragile. Pro-Tek is an epoxy coating used to cover the assembled board to create a strong finish, preventing the LED packages from being damaged from moisture, dust, and mechanical stresses. Pro-Tek can be formulated to be completely clear or tinted. Tinted epoxy is typically used to provide a better black in the display’s off state, increasing its contrast ratio.
