IV. Standard Outdoor Pixel Pitches vs. Fine-Pitch Outdoor LED: A Full Comparison
The outdoor LED display market can broadly be divided into two categories: conventional outdoor pixel pitches (P2.604 and above) and fine-pitch outdoor products (P1.95 and below). The two differ fundamentally in application positioning and performance.
| Comparison |
Standard Outdoor Pitches (P2.60/P2.97/P3.91/P4.81) |
Fine-Pitch Outdoor (P1.3–P1.95) |
| Pixel Density |
147,456–43,264 pixels/m² |
589,824–262,144 pixels/m² |
| Optimal Viewing Distance |
Beyond 5 m; typically over 10 m |
1.3–14 m; close, medium, and long range |
| Resolution Capability |
Large area required for 2K; 4K is difficult |
2K/4K achievable in small to medium areas |
| Image Detail |
Visible pixelation; blurred at close range |
Detailed and pixel-free at close range |
| Applications |
Large long-distance outdoor advertising and highway billboards |
Close-range advertising, wayfinding, commercial and public spaces |
| Installation Space |
Requires a large wall or site area |
Compact footprint and more flexible installation |
In simple terms, conventional large outdoor displays address the need to be visible from far away, while fine-pitch outdoor displays are designed to remain clear and detailed at close range. The two categories complement rather than replace each other.
VI. Holedscreen Fine-Pitch Outdoor LED: A Technical Benchmark
This high-definition, full-color fine-pitch outdoor LED display uses die-cast aluminum modules and an extruded aluminum cabinet structure. The series covers six pixel-pitch options from P1.3 to P4.81, providing a representative solution for fine-pitch outdoor applications.

5.2 Key Technical Highlights
Comprehensive GOB Protection: GOB encapsulation forms a high-strength transparent protective layer over the LED board, effectively improving resistance to water, dust, moisture, and impact. It also enhances stability under high temperatures, intense sunlight, and outdoor temperature fluctuations, reducing the risk of protective-layer delamination, module deformation, and LED detachment while extending the service life of the display.
Common-Cathode Energy-Saving Technology: A common-cathode power architecture keeps the display cooler than conventional common-anode circuitry on average and reduces power consumption, significantly lowering long-term operating costs.
IP66 All-Weather Protection: The integrated design provides corrosion resistance, moisture protection, and salt-spray resistance for reliable long-term operation in demanding environments, including coastal locations. Its fanless design also reduces potential water-ingress points.
Hard-Connection, Cable-Free Design: Concealed hard connections between cabinets create a clean, streamlined appearance. Front and rear maintenance are supported, and the removable power box makes installation and servicing convenient.
Glasses-Free 3D Display: When paired with 90-degree curved cabinets, the system can easily create glasses-free outdoor 3D effects and highly interactive, scenario-based marketing experiences.
Multiple Cabinet Sizes: Cabinet options such as 500 * 500 mm and 500 * 1,000 mm can be combined freely and support floor-standing, suspended, wall-mounted, pole-mounted, and recessed installations.
VI. Nine Key Applications for Fine-Pitch Outdoor LED Displays
The core value of fine-pitch outdoor LED lies in high-definition viewing at close range. This capability enables nine important applications that conventional large-format outdoor displays cannot effectively serve.
1. Bus Shelters
Bus shelters are a typical close-viewing environment, where passengers often stand only 1–3 meters from the advertising display. At this distance, conventional P2.97/P3.91 screens show noticeable pixelation and cannot present fine detail effectively. With a P1.95 or P2.604 fine-pitch display, passengers can clearly read route information, real-time arrival updates, and advertising details, or watch high-definition short videos—improving both advertising value and public information services.
2. Public Spaces: Advertising and Wayfinding for Squares, Exhibition Venues, and More
Public spaces such as city squares, exhibition venue entrances, and cultural centers have heavy foot traffic and a wide range of viewing distances. Fine-pitch outdoor displays remain detailed up close and eye-catching from farther away. They can show city promotional videos or serve as wayfinding displays for venue maps, event schedules, and emergency notices. P2.604–P3.91 offers a balanced choice for these applications and delivers a strong viewing experience at distances of 5–10 meters.
3. Small Public Areas: Advertising Displays for Residential Communities and Sports Grounds
Advertising displays around community squares and neighborhood sports grounds are usually viewed from 3–8 meters, while installation space is often limited. P2.97 or P3.91 fine-pitch displays can deliver high-definition content in a compact footprint for community announcements, property-management notices, and commercial advertising—without taking up excessive public space and while keeping information clear and readable.
