COB LED realizes the conversion of LED units from "point" to "surface" light sources, resulting in a more uniform picture. This significantly improves the contrast of the display screen, greatly eliminates graininess, effectively reduces light intensity radiation, eliminates moiré and glare, and is less prone to causing visual fatigue.
COB((Chip on board))LED technology is an integrated surface light source technology that directly attaches LED light-emitting chips to a highly reflective metal substrate. Its light source has better visual consistency; the luminous points are all on the same reference point, and the illuminated spots are more uniform.
