LED Display Technology
Three terms come up on almost every LED project, and they get mixed up constantly because they describe different things. COB is a packaging method. Micro LED is a chip and substrate technology. Transparent LED describes what the finished display does to light, not how it is built. A single screen can involve all three.
COB packaging
LED chips are bonded directly to the circuit board and encapsulated, instead of being soldered as individual lamps. The surface becomes one flush plane: harder to damage, easier to clean, and front-serviceable. This is what our five indoor fine-pitch models use.
Micro LED on TFT glass
Micro-scale LED chips sit on a semiconductor-grade glass backplane rather than a PCB cabinet. The module gap drops to microns, so the wall reads as a single surface at close range. We currently supply one indoor Micro LED model at P0.7.
Transparent display routes
See-through screens are built three ways: an LED array framed or laminated into glass, a flexible film bonded onto existing glass, or Micro LED on a glass substrate. Each trades transparency, image quality and installation effort differently.
How the choice actually gets made
Technology decides what a display is capable of. Viewing distance decides which of those capabilities you can see. The practical question is not “which technology is best” but “how close does the audience stand, and what has to be readable from there” — which is exactly what the calculator works out.
Turn the theory into a specification. The free LED Pitch Advisor takes your viewing distance and screen wall size and returns two model recommendations with cabinet count and an indicative budget. If you want the background first, read the pixel pitch guide.
