I want to buy an LED display screen, how do I choose the model?

1、 Clarify core requirements

What is the purpose?

Advertising promotion (shopping mall, outdoor)?

Stage performance/event rental?

Meeting room/classroom/monitoring room?

Retail store window display?

Sports venues/live broadcasts of sports events?

Is the installation environment indoor or outdoor?

Outdoor areas should be waterproof, dustproof, and have high brightness (≥ 5000 nits).

Indoor needs to consider resolution, color reproduction, and brightness, usually 1000-2000 nits.

Installation location and spatial dimensions?

The installation height and viewing distance of the screen (determining the selection of point spacing).

The width and height of the installable area (to determine the screen size).

Do you need to move or fix the installation?

Fixed installation: such as building exterior walls and conference rooms.

Mobile rental: requires lightweight and quick disassembly (such as H&S Innovation LED box screen).

2、 Key parameter selection

Pixel Pitch

The smaller the dot spacing, the higher the resolution, making it suitable for close range viewing (such as P1.25-P2.5 for indoor meetings).

The larger the dot spacing, the lower the cost, making it suitable for long-distance viewing (such as P4-P10 for outdoor advertising).

Formula reference: Optimal viewing distance (meters) ≈ Point spacing (mm) × 1.5-2.

Resolution and Size

Determine the resolution based on installation space and content requirements (such as 1920 × 1080).

Screen size=dot pitch x number of pixels (e.g. P3 screen, length 10 meters=10000mm ÷ 3mm ≈ 3333 pixels).

Brightness (nits)

Indoor: 800-2000 nits.

Semi outdoor: 2500-4000 nits.

Outdoor: 5000-10000 nits (avoid direct sunlight and make it difficult to see).

Refresh rate (Hz)

Basic requirement: ≥ 1920Hz-3840HZ (to avoid stripes during phone shooting).

High end scenario: ≥ 7680Hz (stage live broadcast, high-speed motion picture).

Color reproduction degree

The higher the color gamut coverage (such as Rec.709 or DCI-P3), the more realistic the color.

Color depth ≥ 16 bits can reduce color discontinuity.

 Budget and Cost

direct cost

Screen unit price (calculated in square meters).

Supporting equipment (control system, power supply, steel structure, heat dissipation system, etc.).

implicit cost

Installation costs (high-altitude operations, lifting, etc.).

Post maintenance (such as module replacement, repair labor costs).

Brand and after-sales service

Brand selection, certification qualifications, after-sales service

Warranty period (usually 2-5 years).

Do you provide technical support and spare parts inventory.

Details that are easily overlooked

Heat dissipation and power consumption

Maipu Guangcai outdoor screen needs to confirm the heat dissipation design (such as air conditioning or fan).

Power consumption affects electricity bills (e.g. 300-600W per square meter).

Pre maintenance vs post maintenance

Front maintenance: When there is no channel on the back of the screen, the module can be removed from the front.

Post maintenance: A maintenance channel needs to be reserved.

Content playback method

Do you need synchronous/asynchronous control?

Do you need to support 4K/8K signal input?

One sentence summary

Tell the supplier your purpose, installation environment, budget, and expected clarity, and they will match the model for you. If pursuing cost-effectiveness, prioritize mature products with mainstream point spacing (such as indoor P2.5 and P1.86, outdoor P4 and P5).
