LED 포스터 구매 가이드: 적합한 디지털 포스터 디스플레이 선택 방법

What Is an LED Poster and Why Choose One?

An LED poster is a freestanding, plug-and-play digital display that combines the visual impact of a commercial LED screen with the convenience of a portable floor display. Standard dimensions are 640×1920mm — roughly 2.1 feet wide by 6.3 feet tall — supported by a slim aluminum frame and four lockable caster wheels.

Unlike fixed LED walls that require structural mounting, professional installation crews, and permanent cable routing, an LED poster ships 완전히 조립. You unbox it, roll it into position, plug it into a standard wall outlet, and content starts playing — from USB, WiFi, or cloud.

Why choose LED poster over LCD poster? Seamless multi-screen splicing, higher brightness (2× brighter), and wider viewing angles (160° vs 89°). If your space has ambient light — windows, spotlights, open ceilings — the brightness advantage alone justifies the cost difference.

Why choose LED poster over fixed LED 벽? Mobility, zero installation cost, and the ability to repurpose the display across multiple locations and campaigns. If your advertising position changes — seasonal promotions, rotating event spaces, store remodeling — a poster recovers its cost faster than a permanently mounted wall.

올바른 픽셀 피치 선택

Pixel pitch is the distance between the centers of two adjacent LED pixels, measured in millimeters. Smaller number = finer image = closer you can stand without seeing individual dots. For LED posters, the practical range is P1.25 to P2.5.

COB vs GOB vs SMD — Which Encapsulation?

Encapsulation determines how LED chips are packaged and protected. For LED posters, three technologies dominate. Your choice depends on where the poster lives and what it faces — foot traffic, humidity, dust, cleaning requirements.

COB (Chip on Board) — Premium, P1.2–P1.8

LED chips bonded directly to the PCB and fully encapsulated in epoxy resin. The surface becomes a single smooth panel — no exposed diodes, no gaps between pixels. This delivers IP54 protection (wipe clean with a damp cloth), 5H surface hardness (keys and shopping carts won’t scratch it), and 20,000:1 contrast ratio (deep blacks even in bright ambient light).

다음의 경우 COB를 선택하세요: Your poster is in a luxury retail environment, a museum, or any space where viewers stand close (<2m). The image quality is visibly superior, and the durability eliminates the anxiety of accidental damage.

GOB (Glue on Board) — Protected, P1.5–P2.5

A 2mm transparent epoxy layer applied over standard SMD LEDs. Adds impact resistance, moisture protection, and dust sealing without the cost premium of full COB encapsulation. GOB posters handle busy environments where bumps, splashes, and cleaning crews are daily realities — shopping mall corridors, transportation hubs, food courts.

다음과 같은 경우 GOB를 선택하세요: Your poster will be in a high-traffic public space. The 10–15% cost premium over SMD pays for itself in reduced dead pixels and fewer replacement modules over the poster’s lifespan.

SMD (Surface Mount) — Budget, P1.8+

Traditional surface-mounted LED diodes. The most cost-effective option for controlled indoor environments where physical contact with the screen is unlikely — corporate lobbies, meeting room corridors, supervised retail spaces.

다음과 같은 경우 SMD를 선택하세요: Budget is the primary constraint and your poster will be in a low-contact, climate-controlled indoor environment. Accept that exposed LED beads are vulnerable to impact damage.

Form Factor — Standard vs Foldable vs Tri-fold vs Dual-Sided

LED posters come in four physical configurations. Each solves a different deployment challenge.

표준 LED 포스터

Fixed aluminum frame, 640×1920×64mm, ~27kg. The default configuration. Ships fully assembled. Best for permanent or semi-permanent placements — retail stores, hotel lobbies, corporate reception — where the poster stays in one location for weeks or months.

접이식 LED 포스터

Hinged frame that folds to roughly half its deployed size. As thin as 35mm. Under 30kg. Designed for events, exhibitions, and rental operations where transport and storage space matter. Fits through standard doorways and elevators when folded. Some models include an integrated battery pack for 3–6 hours of cordless operation.

3단 접이식 LED 포스터

Three-panel folding design with adjustable angles. Creates an immersive, wraparound visual experience. Popular for trade show booths, pop-up retail activations, and product launches where a flat screen isn’t enough. The angled panels catch peripheral vision from multiple approach paths.

Dual-Sided Display Option

Displays different content on front and back. Available on standard and foldable models. Doubles reach in corridors, open-plan retail floors, and event aisles where traffic flows past both sides of the poster. Each side operates independently — you can run brand content on one side and promotional offers on the other.

Control System and Content Management

The control system is the brain of your LED poster. A good screen with a bad controller still produces a bad result. DOIT VISION posters ship with Novastar TB40 controllers as standard — the industry’s most widely adopted platform.

Four Ways to Manage Content

1. USB 플러그 앤 플레이 — Load media files onto a USB drive, insert it into the poster. Content plays automatically on a loop. No network required. Simplest option for single-post locations.
2. WiFi via Viplex Handy App — Control content from an iOS or Android phone. Upload videos, images, and text. Schedule playlists. Adjust brightness. All from your pocket.
3. HDMI Direct Input — Connect a laptop or media player for real-time screen mirroring. Useful for presentations, live data dashboards, or when content is generated by external software.
4. Novastar VNNOX Cloud Platform — Enterprise-grade remote management. Push content to hundreds of posters simultaneously. Schedule campaigns by date, time, and location. Monitor device health, receive fault alerts, and adjust settings — all from a browser. Essential for multi-location retail chains.

Multi-Poster Splicing Limits

When connecting multiple posters into a single larger display, the Novastar TB40 controller imposes limits based on pixel pitch:

• P1.25: up to 2 units linked
• P1.53: up to 4 units linked
• P1.86: up to 6 units linked
• P2.5: up to 8 units linked

For installations exceeding these limits, contact us for a custom controller configuration.

LED Poster Price Guide: What to Expect by Configuration

LED poster pricing varies by five factors: pixel pitch, encapsulation, LED brand, cabinet design, and control system. All prices below are factory-direct (EXW Shenzhen). Shipping, customs duties, and local installation are additional.

What Affects Price Beyond the Spec Sheet

• LED 브랜드 : Nationstar adds 15–25% over Kinglight. The premium buys higher brightness consistency, better binning tolerance, and longer stability — visible in side-by-side comparisons but not in isolation.
• 캐비닛 디자인: Foldable mechanisms add $300–$600 per unit. Dual-sided displays add 60–80% over single-sided. Battery modules add $200–$400.
• 수량 할인: Orders of 10+ units typically receive 5–10% discount. Orders of 40+ units (like our US retail chain case) receive volume pricing — contact us for a quotation.
• 맞춤 측정기준: Standard is 640×1920mm. Custom sizes (like AV Group Denmark’s 600×2025mm) require retooling and add $200–$500 per unit for small batches.

주문하기 전에 공급업체에 문의해야 할 질문들

These seven questions separate factories from trading companies. A supplier who cannot answer all seven clearly is likely reselling someone else’s product.

1. Can I see a video of my assembled posters before they ship?

   We send photos and video of every order after the 72-hour aging test. You see exactly what leaves our factory.

2. What LED brand are you using and can I verify the chip marking?

   LED chips have laser-etched brand markings. If a supplier claims Nationstar but won’t show you the chip surface under magnification, something is off.

3. What is your dead pixel policy and replacement procedure?

   Industry standard is ≤0.01% dead pixels out of the box. We guarantee replacement modules dispatched within 48 hours if a module exceeds this threshold during warranty.

4. Do you provide CAD drawings and mounting specifications?

   For custom projects, we supply full mechanical drawings, wiring diagrams, and installation guides before shipment.

5. What control system ships with the poster and is it locked to your firmware?

   Standard Novastar TB40 — not locked, not branded, fully compatible with the entire Novastar ecosystem.

6. Can you share a reference client or case study with a similar deployment?

   We maintain detailed case logs. If we’ve done a project like yours, we’ll share it. If we haven’t, we’ll tell you — and explain how we’d approach it.

7. 판매 예상치가 아닌 실제 리드 타임은 얼마입니까?

   We commit to 7–15 working days for standard models. Custom configurations: 15–25 working days. Large bulk: 25–35 working days. When we give you a date, it’s based on the production schedule — not optimism.
