COB Series Indoor Fine Pitch LED Display
Chip-on-board fine pitch: the LEDs are sealed inside, so the screen shrugs off touch, dust, moisture and knocks.
Why teams choose the COB Series
Conventional SMD fine-pitch displays leave the LED exposed — one knock during transport or one curious finger and pixels die. The COB Series solves this at the packaging level: chips are bonded directly to the board and sealed under a protective layer, making the display genuinely waterproof, dustproof and impact resistant. COB packaging also produces a softer, more comfortable image with no visible pixel graininess, which suits close viewing distances, bright indoor ambient light and long viewing sessions. Built on the same 600×337.5×27.5mm die-cast aluminum platform as our X3 Series with full front maintenance, the COB Series is the premium choice for boardrooms, broadcast and any space where people get close to the screen.
Sealed COB packaging
LEDs are integrated and sealed at chip level — waterproof, dustproof and impact resistant where SMD cannot be.
Softer close-range image
No pixel graininess and gentler light output make COB ideal for close viewing and long meetings.
Ultra-fine pitches
P0.78, P0.9 and P1.25 deliver 4K/8K resolution walls at short viewing distances.
Dual backup system
Optional dual power and dual receiving card for uninterrupted operation.
Front maintenance platform
Same slim 27.5mm die-cast cabinet as the X3 — flush wall mounting, fanless and silent.
