COB chip and pin legs are sealed, resulting in better airtightness, higher resistance to external forces, and a smoother, seamless surface.
COB has a much higher level of protection against moisture, electrostatic discharge (ESD), damages, and dust with surface protection rated IP65. COB is an integrated package with even light distribution, and the smooth surface makes images appear softer and friendlier to the human eye.
Superior Durability : COB is better at withstanding collisions and the effects of Oil, Damp, Water, Dust, Oxidisation, and dust.
High Contrast Ratio: The contrast ratio of LED displays is an important parameter that determines how clear, vivid, and colorful the image is .COB can reach 15,000 to 20,000 static contrast ratio and up to 100,000 high dynamic contrast ratio.
