In indoor LED display projects, pixel pitch determines image clarity, optimal viewing distance, and overall budget. As fine-pitch LED technology becomes more accessible, P4, P3.076, P2.5, P2.0, P1.86, P1.53, and P1.25 have emerged as the most popular high-resolution options.
These specifications differ not only in numbers but also in clarity, ideal applications, and cost. This guide will walk you through the core parameters, real-world scenarios, and practical product recommendations to help you make the right choice.
1. Clarity and Viewing Distance
Pixel pitch refers to the distance in millimeters between the centers of two adjacent pixels. Smaller pitches mean more pixels per square meter, delivering finer images but also increasing cost, power consumption, and cooling requirements.
-
P4 (4.0 mm) – ~62,500 pixels/㎡; recommended viewing distance ≥4 m. Ideal for stage backdrops, large conference screens; visible pixelation at close range.
-
P3.076 (3.076 mm) – ~105,688 pixels/㎡; recommended viewing distance ≥3 m. Popular for shopping mall advertising screens and corporate exhibition halls.
-
P2.5 (2.5 mm) – ~160,000 pixels/㎡; recommended viewing distance ≥2.5 m. Delivers excellent detail and color depth; great for control rooms and retail windows.
-
P2.0 (2.0 mm) – ~250,000 pixels/㎡; recommended viewing distance ≥2 m. Suited for exhibition halls and high-end meeting rooms.
-
P1.86 (1.86 mm) – ~288,000 pixels/㎡; near Full HD clarity at ≥1.8 m; ideal for studios and control centers.
-
P1.53 (1.53 mm) – ~426,000 pixels/㎡; recommended viewing distance ≥1.5 m. Print-like detail for immersive installations and premium control rooms.
-
P1.25 (1.25 mm) – ~640,000 pixels/㎡; remains sharp from just 1 m away. Best for ultra-high-precision data displays and virtual studios.
2. Cost and Maintenance
Smaller pixel pitches require more LEDs, driver ICs, and control hardware, leading to higher initial investment. They also consume more power and generate more heat, which demands better cooling and power management.
-
P4 to P2.5 – Balanced clarity and cost; easy to install and maintain; suitable for high-quality displays with moderate budgets.
-
P2.0 to P1.25 – Premium fine-pitch displays; higher initial investment and stricter technical requirements; designed for high-end applications.
Using GOB (Glue on Board) protection significantly improves resistance to dust, moisture, and impact—ideal for high-traffic or touch-interactive installations.
3. Real-World Applications
Trade Show Stage – P4
A major exhibition used P4 modules for its main stage background. From 4–10 m, text, logos, and videos were sharp and bright, with a balanced cost-to-performance ratio.
Retail Window – P2.5
A luxury brand installed P2.5 indoor screens in its flagship store window to showcase new collections. From 2–3 m, visuals were vivid and highly detailed, drawing in passers-by.
Corporate Showroom – P1.86
A tech company used P1.86 screens to present 4K videos and product details in its showroom. Visitors standing 2 m away enjoyed smooth, grain-free images with a premium feel.
Traffic Control Center – P1.25
A city control center deployed P1.25 fine-pitch displays for multi-channel live video and map monitoring. Operators could work comfortably at close range with precise detail visibility.
