LED Circuit Boards（PCB)– the basement of the building. “LED Boards”, “LED blocks”, “LED panels”, “LED modules”, “LED cabinets” or simply “LED displays,” along with numerous other designations in the culture-specific parlance of the individual manufacturer, are in effect the biggest differentiated when comparing one SMD LED solution to another. These “Boards” are made up of a number of electronic sub-components including layers of reinforced fiberglass.
These layers house power circuitry and electrical grounding. Also, electronic circuitry to deliver, drive, and distribute both data for rendering the digital content and electricity to power the LED (Light Emitting Diode) will be housed in these layers. With respect to the “pixels” – the individual RGB LED packages – there are circuitry, diodes, resins, design elements, and peripheral surfacing materials/colors to consider as well.
Industry standards show that current typical circuitry design renders somewhere in the 60%-75% range as the percentage of wattage converted to light in the displays. This means the remaining 40%-25% of wattage is converted to heat. Depending on the environment where the display solution will be used that could be a problem. Imagine LED displays emitting a high level of heat in a high-end retail cosmetics store adjacent to say a lipstick PoP structure. There is a handful of tier 1 (read: high-quality) display manufacturers who are the elegance of design with their circuitry, is rendering conversion percentages approaching 85% to-light efficiency.
