In LED display procurement, most buyers fall into the trap of "the better the parameters, the better", blindly pursuing high configurations while ignoring scenario compatibility. This ultimately leads to budget waste, poor display performance and even soaring post-operation maintenance costs.

 

The core of choosing a suitable LED display lies not in stacking high-end parameters, but in accurately matching usage requirements. This article focuses on three core parameters—pixel pitch, resolution and IP rating, providing plain-English explanations and scenario-based selection suggestions to help buyers avoid traps and efficiently select cost-effective, suitable products.

 

1. Pixel Pitch: Smaller Is Not Always Better, Match Viewing Distance for Cost-Effectiveness

 

As the primary reference parameter for LED display procurement, pixel pitch directly determines image delicacy and applicable scenarios. A wrong choice will easily cause overkill or insufficient image quality.

 

Pixel pitch refers to the center distance between two adjacent lamp beads on the display, measured in millimeters (mm). The smaller the value, the denser the lamp beads, and the finer the image without graininess when viewed up close.

 

Scenario-Based Selection Guide

 

• Small pixel pitch (P1.2-P2.5): Suitable for short-distance viewing scenarios (1-5m viewing distance) such as meeting rooms, corporate exhibition halls and command centers. Features high image definition, clear text and HD visuals, ideal for office presentations and data visualization.

 

 

• Medium pixel pitch (P3-P6): Balances image quality and cost, fit for medium-distance viewing scenarios (5-10m viewing distance) like shopping mall advertising screens, auditoriums and lecture halls, clearly displaying full-color images and promotional content.

 

 

• Large pixel pitch (P8-P16): Designed for long-distance viewing scenarios (over 10m viewing distance) including outdoor large screens, road traffic screens and park notice screens. With strong heat dissipation, it prioritizes long-distance visibility and durability. 

 

 

Mistake Prevention Reminder

 

Pixel pitch is not as small as possible. Blindly choosing ultra-small pixel pitch displays will double procurement costs, and fail to exert their image advantages in long-distance viewing scenarios, resulting in unnecessary budget waste.

 

2. Resolution: Don’t Blindly Chase 4K, Screen Size & Material Compatibility Matter Most

 

Resolution is the core indicator of LED display sharpness. Many buyers blindly pursue 4K while neglecting compatibility with screen size and scenarios, leading to undesirable results.

 

LED display resolution is divided into physical resolution and display resolution: physical resolution refers to the total number of horizontal and vertical lamp beads of the display, its inherent attribute; display resolution refers to the resolution of playing materials. Only when the two match can the optimal display effect be achieved.

 

 

Scenario-Based Selection Guide

 

• Small-size displays (≤5㎡): Such as small meeting room screens and store window screens, prioritize high physical resolution to clearly display PPT text and product details, avoiding blurriness.

 

 

• Large-size outdoor displays (≥20㎡): Like square advertising screens and highway indicator screens, no need to blindly pursue 4K physical resolution. Simply ensure matching between physical resolution and playing material resolution—long-distance viewing scenarios only require qualified material resolution to meet visual needs. 

 

 

Mistake Prevention Reminder

 

If the playing materials themselves lack clarity, even high-resolution displays cannot improve the effect. Plan material production standards in advance before procurement to avoid putting the cart before the horse.

 

3. IP Rating: Wrong Choice Causes Easy Damage, Scenarios Determine Protection Standards

 

 

IP rating directly determines the durability and environmental adaptability of LED displays. An incorrect choice will easily lead to short circuits, lamp bead damage and skyrocketing post-operation maintenance costs.

 

LED display IP rating is marked as "IP + two digits": the first digit indicates dustproof grade (0-6, higher = stronger dustproof ability); the second digit indicates waterproof grade (0-8, higher = stronger waterproof and moisture-proof ability). Focus on these two digits during daily procurement.

 

Scenario-Based Selection Guide

 

• Indoor scenarios (offices, meeting rooms, exhibition halls): Dry environment without dust and rain interference, choose IP30-IP40. Lightweight and easy to install, meeting indoor stable use needs.

 

• Semi-outdoor scenarios (advertising screens under shopping mall awnings, community gate notice screens): Need both dustproof and splash-proof functions, recommend IP54 to resist slight rain and dust.

 

• Full outdoor scenarios (open square large screens, road traffic screens, coastal scenic spot screens): Need to cope with harsh environments like heavy rain, exposure and dust, must choose IP65 or above. Professionally sealed to ensure long-term stable outdoor operation. 

 

Mistake Prevention Reminder

 

Low IP rating displays used outdoors will easily suffer internal circuit short circuits in rainy seasons, and dust accumulation affecting heat dissipation in high temperatures. This not only shortens service life, but also leads to post-maintenance costs far exceeding the initial procurement savings.

 

4. Core Selection Formula: Quick & Mistake-Free Implementation

 

Short distance → small pixel pitch + high resolution + low IP rating (indoor)

 

Long distance → large pixel pitch + matching resolution + high IP rating (outdoor)

 

Limited budget → prioritize scenario compatibility over blind parameter pursuit

 

5. Full-Scenario LED Display Selection Support, Accurate Demand Matching

 

In summary, the core logic of LED display procurement is "scenario compatibility first, parameters selected on demand". Mastering the three core parameters (pixel pitch, resolution, IP rating) helps avoid most procurement traps.
