Chip-on-Board: Ein Substrat, Keine sichtbaren Nähte

COB stands for Chip-on-Board. Instead of packaging each LED individually and mounting it onto a PCB like SMD (Surface-Mounted Device), COB bonds multiple flip-chip LEDs directly onto a single substrate, then encapsulates the whole surface. The result is a smoother, more uniform display surface with less visible pixel structure at close range, higher contrast, and better resistance to moisture, dust, and physical impact than individually packaged LEDs.

DOIT VISION has built flip-chip COB technology into five product lines — fine pitch (COB Pro, COB Beta), portable signage (COB Poster), creative cube displays (COB Cube), and integrated meeting-room displays (All-in-One LED TV). We’re a Shenzhen-based manufacturer founded in 2013, with 15 in-house engineers and products shipped to 55+ countries.

Wie COB Vergleicht

COB is one of three main LED packaging routes. Here’s how it stacks up against the alternatives, with links to our full engineering breakdowns.

Verpackungs-

COB vs. SMD

SMD packages each LED individually — cheaper up front, more design flexibility. COB bonds chips onto one substrate — seamless surface, better moisture resistance, lower 5-year maintenance cost.

Feiner Pitch

COB vs MIP

MIP factory color-bins each mini-LED before mounting, reaching 100,000:1 contrast and single-LED field repair at a 20–40% premium over COB Pro. COB Pro is the standard choice for most control rooms.

COB vs GOB (Poster)

For LED posters specifically, COB competes with GOB (Glue-on-Board) encapsulation. Different durability, cost, and repair trade-offs for portable, frequently-moved digital signage.

Markt Trend

Warum COB wächst

Micro COB adoption has accelerated in fine pitch since 2024 as chip yields improved and prices dropped closer to SMD. Where the market is heading through 2026.

COB-LED-Anzeige FAQ

Beantwortet vom DOIT VISION-Entwicklungsteam.

COB (Chip-on-Board) mounts multiple LED chips directly onto a single substrate before encapsulation, instead of packaging each LED individually like SMD. The result is a smoother surface with less visible pixel structure, higher contrast, and better moisture resistance. DOIT VISION uses flip-chip COB across five product lines: COB Pro, COB Beta, COB Poster, COB Cube, and our All-in-One LED TV.

COB Pro is our 16:9 flagship — 600×337.5mm cabinets, P0.62 to P1.875, up to 10,000:1 contrast, built for control rooms and broadcast studios. COB Beta is 4:3, 640×480mm cabinets, P1.25 to P1.86, sized for multi-screen control walls and retail. They use different cabinet dimensions and cannot be tiled together — decide your aspect ratio first.

It depends on the application, not a universal “better.” COB wins on seamlessness, contrast, and moisture resistance — better for immersive walls and control rooms. SMD wins on design flexibility and lower upfront cost. Full 5-year cost comparison in our COB vs SMD TCO analysis.

COB Pro delivers up to 10,000:1 contrast and covers P0.62–P1.875 at standard fine pitch pricing. MIP factory color-bins each mini-LED individually, reaching 100,000:1 contrast and single-LED field repair, at a 20–40% price premium. Choose MIP for 24/7 mission-critical screens; choose COB Pro for most control room and broadcast projects.

Novastar and Colorlight sending boxes and video processors are compatible with all our COB product lines — COB Pro, COB Beta, COB Poster, and COB Cube. We recommend the specific sending card and processor model based on your screen resolution and refresh rate requirement during quotation.

COB typically carries a premium over standard SMD at the same pixel pitch, since flip-chip mounting and encapsulation add manufacturing steps. The gap narrows at finer pixel pitches (below P1.5) where SMD’s own packaging cost rises. Exact pricing depends on pitch, cabinet size, and order volume — request a quote for a same-day number.

Five product lines: COB Pro (fine pitch, 16:9), COB Beta (fine pitch, 4:3), COB Poster (freestanding digital signage), COB Cube (4/5/6-sided creative display), and our All-in-One LED TV (108″–163″ integrated meeting room display). Each targets a different application — see the product cards above to find yours.
