The LED display screen is used for monitoring the core, which is an indoor screen with small spacing (P0.9~P1.5), seamless splicing, and stable operation for 7 × 24 hours. It is combined with a decoder and video processor to achieve centralized display, segmentation, roaming, and scheduling of multiple monitoring images.

1、 Core advantages (compared to LCD splicing screens)

-  ✅  Seamless splicing: No physical seams, the entire screen is complete, and the map/panoramic monitoring is not fragmented.

-  ✅  High brightness and high contrast: Indoor 500-1500 cd/㎡, contrast ratio ≥ 3000:1, clear strong/low light environment.

-  ✅  Ultra wide viewing angle: 170 ° -175 °, multiple workstations can be viewed simultaneously without color difference.

-  ✅  Ultra long lifespan: ≥ 100000 hours, supporting 7 × 24-hour uninterrupted operation.

-  ✅  Flexible splicing: can be curved/irregular, suitable for the large screen wall of the command center.

-  ✅  Low latency: ≈ 50ms, real-time monitoring without ghosting.

2、 Mainstream application scenarios

-Public security/traffic command center: Multi screen segmentation, real-time monitoring of intersections/road sections, and rapid dispatch.

-Emergency Command Hall: Large seamless screen, integrating videos, maps, and data for global control of emergency events.

-Park/Factory Security: Centralized display of entrances and exits, walls, and monitoring of key areas, with real-time alerts for any abnormalities.

-Power/energy dispatch: high stability, suitable for industrial environments, 7 × 24-hour monitoring equipment operation.

3、 Key parameter selection (monitoring room)

-Point spacing (P):

-2-3 meter line of sight: P1.25 (high-definition, clear face/license plate)

-3-5 meter line of sight: P1.5-P1.86 (high cost-effectiveness)

-Sight distance above 5 meters: P2.0-P2.5

-Brightness: Indoor 800-1200 cd/㎡, supports automatic dimming, eye protection and anti reflection.

-Refresh rate: ≥ 3840 Hz, low brightness and high gray, no flickering on the monitoring screen.

-Packaging: Priority is given to COB (dustproof, moisture-proof, impact resistant, etc.) IP65， The failure rate is extremely low.

4、 System composition (how to connect monitoring)

1. Front end: Network Camera (IPC) → Switch → Hard Disk Video Recorder (NVR) storage.

2. Decoding: Switch → HD decoder (Hikvision/Dahua/Keda), converts network video to HDMI/DVI.

3. Control: Decoder → Video Processor/Splicer (Nova/Kalette) to achieve image segmentation, windowing, roaming, and scaling.

4. Display: Processor → LED screen control system → Small pitch LED large screen.

5. Auxiliary: Control computer, power supply, heat dissipation, lightning protection and grounding.

5、 Key points for installation and maintenance

-Installation method:

-Wall mounted: saves space and is suitable for flat walls.

-Front maintenance: Priority given to small space (no need for rear channel).

-Post maintenance: Adequate space selection, low cost, and convenient maintenance.

-Maintenance:

-Heat dissipation: Leave a gap of ≥ 30cm on the back to ensure ventilation.

-Moisture proof: Humidity range of 10% -90% RH to prevent corrosion of the circuit board.

-Cleaning: Gently wipe with a soft cloth, do not spray water directly.

-Power supply: dual power supply+redundancy, anti power-off black screen.

6、 Common problems and pitfalls to avoid

-  ❌  Close range particle sensation: Choose P1.25 or below, COB packaging is more delicate.

-  ❌  Screen lag: Use a gigabit switch+high-definition decoder, Ethernet cable ≤ 100 meters, and fiber optic cable for long distances.

-  ❌  Brightness discomfort: Supports automatic dimming, automatically reduces brightness at night to prevent glare.

-  ❌  Budget too high: Select point spacing based on line of sight, balance effect and cost on P1.5.

7、 How to choose a splicing screen with LCD

-Select LED: Requires seamless, ultra wide viewing angle, 7 × 24-hour stability, curved/irregular shape.

-Choose LCD: limited budget, close line of sight (<2 meters), extremely high single screen resolution requirements (such as 4K).
