LED ディスプレイ設置ガイド: 計画から起動までのステップバイステップ

私. Preliminary Communication: Lock Down Requirements (Or Regret It Later)

1. Confirm Installation Location & タイプ

• Mounting Style: Is it recessed (built into a wall), wall-mounted, or freestanding? For recessed screens, remind the client to reserve carpentry space 10mm larger than the screen (例えば, a 3940×2020mm screen needs 3950×2030mm). そうでない場合, you’ll be hacking into walls to make it fit—trust me, it’s not fun.
• 環境: 屋内または屋外? Outdoor screens need a waterproof back panel (aluminum composite or OSB board). Indoor recessed screens don’t, but they must have 300mm of depth for heat dissipation.

2. Nail Down Screen Specs

• ピクセルピッチ: This is non-negotiable. Indoor screens use P2/P3 (smaller = sharper). Outdoor screens need P10/P16 (bigger pixels = less glare).
• Dimensions: Calculate screen size using module dimensions. 例えば, ある P2 module (320×160mm) ニーズ 12 modules for a 3.94m-wide screen (12×320mm=3840mm—add 10mm for frame tolerance). Pro tip: Always confirm the visible display area with the client—not the outer frame. Most clients mix these up!

3. Agree on Aesthetics

• If the client wants black brushed titanium edging, clarify: Edging clips onto the frame and must be installed after the screen is assembled. Install it too early, and you won’t fit the modules.

Ⅱ. 材料 & ツール: List Everything (No Last-Minute Runs)

1. Material List (Indoor P2 Embedded Screen Example)

2. Tool List (Essential—No Shortcuts)

• Cutting: Cutting machine (aluminum profiles), angle grinder (edge finishing).
• インストール: Hand drill (self-tapping screws), crimping pliers (ribbon cables), wire stripper (power cables).
• デバッグ: Multimeter (voltage checks), spirit level (モジュールの平坦度).

Ⅲ. Frame Assembly: Precision Is King—1mm Off = Big Problems

1. Cut & Assemble the Frame

• Measure twice, cut once: Cut aluminum profiles to match the screen’s net size (subtract 4mm for tolerance—5mm if over 3m).
• Secure corners: Use self-tapping screws to attach corners to profiles. Tighten firmly—loose corners = wobbly frame.

2. Install Magnetic Rails

• Align magnetic rails with module height (例えば, 160mm for P2 modules). Make sure rails are level—use a spirit level! Unlevel rails = uneven modules.

Ⅳ. Module Assembly: Slow & Steady—Rushing = Mistakes

1. Lay Out Modules Correctly

• Follow the arrow: Modules have a direction arrow—point it right/down (consistent for all). Wrong direction = inverted images.
• Check flatness: Use a spirit level on every module. Height difference ≤1mm—any more, and the screen will look “bumpy.”

2. Secure Modules & Fix Gaps

• Magnet placement: Attach magnets to module corners (not just the center). This keeps modules flat and stable.
• Gap consistency: Keep module gaps ≤0.5mm. Big gaps = broken text during playback.

3. Critical Pitfalls to Avoid

• Don’t knock the LEDs! P2 LEDs are extremely small—just one bump can cause a dark spot.
• Always support the module from the back, never touch the front.

v. Wiring: Do This Right—Or Burn Your Boards

1. Power Cable Rules (Don’t Reverse Polarity!)

• VCC/+5V = positive: GND/COM = negative. Double-check—this is non-negotiable.
• Parallel, not series: Power modules in parallel (positive to positive, negative to negative). Series wiring = voltage drops = burnt boards.

2. Ribbon Cables & Control Card Setup

• Ribbon cable direction: Red edge faces left. Wrong direction = misaligned images.
• Control card power: Use a dedicated 5V line from the power supply—no module power! Unstable voltage = frozen screens.
• Network cable limits: Don’t overload. 650k pixels per cable—add more if needed.

VI. Cleaning: Small Debris = Big Troubles

• Wipe the frame with a dust cloth.
• Blow module gaps with a hairdryer—get rid of every piece of debris.

Ⅶ. Power-Up Testing: Follow the Sequence—Don’t Guess

1. Connect & Configure the Control Card

• WiFi setup: Connect your phone to the control card’s WiFi (default: 12345678).
• Set parameters:
  • 解決: 3940mm×2020mm P2 screen = 1970×1010 dots.
  • Scan mode: P2 modules use 1/16 scan—select it!

2. Test for Issues

• Test pattern: Display red/green/blue/white. Look for dark spots (bad LEDs) or lines (loose ribbon cables).
• Video test: Play a video—check for blur (enable high refresh) or stutter (add network cables).

VIII. Final Steps: Edge Trim & Client Acceptance

1. Install Edge Trim

2. Client Walkthrough & トレーニング

• Live view only: Don’t use a phone camera—LED screens look bad in photos. Let the client see the real effect.
• Train them: Show how to change content, adjust brightness, and troubleshoot basic issues. This saves you future calls!

Final Pitfall Summary (Save This!)

1. Pre-communication: Nail location, specs, and aesthetics—no assumptions.
2. Wiring: Parallel power, correct polarity—double-check every connection.
3. Cleaning: Debris = short circuits—don’t skip it.
4. Power sequence: Power supply first, then control card.
