Searching “P1.5 LED display” usually means you need an indoor HD screen that balances viewing distance and budget. Start with Block P1.5625 for a conventional SMD/GOB fixed wall, COB Pro for a protected premium surface, COB Beta for 4:3 or special layouts, or an All-in-One for a standard meeting-room size. Poster and curved P1.5 builds remain useful secondary routes. This guide compares those choices with exact 4K cabinet math and 2026 panel prices.

Key Takeaways
  • P1.5 is the volume sweet spot. For closest seats around 2–4 m with mixed video, P1.5 usually matches what the eye can resolve — finer pitch often buys invisible pixels. Check distance on the LED Display Calculator.
  • When P1.5 beats P1.2: same room, mid-distance seating, text that is not micro-SCADA — reclaim budget vs the P1.2 form-factor hub.
  • Exact 4K (worked example — COB Pro P1.5625): 10×10 cabinets of 600×337.5 mm (384×216 px each) = 3840×2160 on a 6.0 × 3.375 m wall (~20.25 m²) — larger than the P1.25 Exact-4K footprint.
  • 2026 panel-only bands: Block P1.5625 about $1,415–1,530/m²; COB Pro P1.5625 about $1,390–1,695/m². Controllers, structure, installation and commissioning typically add 20–40%.
01 — Naming

What a P1.5 LED Display Actually Means (P1.5 / P1.53 / P1.56 / P1.5625)

A P1.5 LED display sits in the ~1.5 mm indoor fine-pitch band — centre-to-centre spacing between pixels. At 1.5625 mm you get about 409,600 pixels per square metre. That density is why boardrooms, classrooms, and mid-size lobbies specify this band when the front row is a few metres back, not handshake-close.

Search and sales talk say “P1.5.” Datasheets often say 1.5 / 1.538 / 1.56 / 1.5625 mm. All of those land in the same commercial cluster. Your purchase order must copy the millimetre on the module drawing — not the Google keyword.

Worked example — published SKUs in this band

Published indoor routes include COB Pro P1.5625, Block P1.5625, Brick P1.56, COB Beta P1.538, Poster COB / Foldable P1.538 and All-in-One 135″ / 163″ P1.5625. Flexible Fixed can be engineered around the required radius. Write the exact pitch, module size and cabinet resolution from the datasheet in every RFQ.

Pitch alone still does not pick the product. The useful indoor decision is between a conventional fixed wall, a protected COB wall, a plug-and-play All-in-One, or a narrower secondary format such as a poster or curved installation. Section 03 routes those products; Section 02 decides whether P1.5 or P1.2 fits the viewing distance.

02 — P1.5 vs P1.2

When P1.5 Beats P1.2 — Distance First, Brochure Second

P1.5 LED Display: When It Beats P1.2, Specs, 4K Size & 2026 Price 4

Rule of thumb: about 1 mm of pitch per 1 m of closest viewing distance. For P1.5 the floor is ~1.5 m. The commercial sweet spot for video-heavy rooms sits nearer 1.5–4 m. Past ~5 m, P1.5 and P1.8 start looking the same for motion content — and P1.2 is almost always wasted CapEx.

Stay on P1.5 when…
  • Closest seats ~2–4 m (typical boardroom table length)
  • Content is mixed video, slides, branding — not dense SCADA at arm’s length
  • You want to preserve budget for processing, structure, spares and commissioning
  • SMD / Block / Brick supply chain and field rework matter
Step to P1.2 when…
  • Viewers stand within ~1.5–2 m of a brand wall or showroom face
  • People wipe or brush the surface (sealed COB earns its keep)
  • Micro text / operator consoles sit inside the pitch floor
  • See the full form-factor hub: P1.2 LED display guide
Engineer note from real rooms

For boardrooms with 2–4 m seating, compare P1.5 and P1.2 using the smallest real text and the closest seat. P1.5 often preserves more budget for processing and structure while still delivering the required detail. Full logic: viewing distance guide and pixel pitch formula guide.

Which Indoor P1.5 Product Fits Your Project?

P1.5 LED Display: When It Beats P1.2, Specs, 4K Size & 2026 Price 5

For most P1.5 searches, begin with the indoor installation model. Block is the conventional SMD/GOB fixed-wall route; COB Pro prioritises a protected premium surface; COB Beta suits 4:3 or special layouts. All-in-One, Poster and Flexible/Curve solve narrower indoor briefs without turning this page into a catalogue of every product shape.

  • The COB Pro, Block and Brick routes used in this guide carry CE, EMC and RoHS. Match every document to the exact quoted series and configuration.
04 — Packaging

COB vs SMD/GOB at P1.5 — Choose by Surface and Service

At P1.2, sealed COB is often the default for close view. At P1.5, quality SMD / GOB (Block, Brick) remains a mainstream, field-serviceable choice. COB is the upgrade for touch, cleaning, and contrast — not the only honest answer.

If your priority is… Choose Why
Lowest panel cost + lamp-level field rework SMD / 4-in-1 / GOB Mature supply; Block / Brick volume path; more surface texture than COB
Touch / cleaning + high contrast + long TCO COB Sealed surface; price table marks COB best long-term TCO at P1.5

06 — 4K Sizing

How Many Cabinets for Exact 4K at P1.5625?

P1.5 LED Display: When It Beats P1.2, Specs, 4K Size & 2026 Price 6

Worked example — COB Pro P1.5625 cabinets: 600 × 337.5 mm, 384 × 216 px per cabinet. True 4K UHD is 3840 × 2160.

  • Cabinets wide = 3840 ÷ 384 = 10
  • Cabinets high = 2160 ÷ 216 = 10
  • Total cabinets = 100 (10 × 10)
  • Screen size = 10 × 0.6 m × 10 × 0.3375 m = 6.0 × 3.375 m ≈ 20.25 m²
  • Native resolution = exact 3840 × 2160
Why Exact 4K at P1.5 is a bigger wall than at P1.25

COB Pro P1.25 Exact 4K is 8×8 cabinets on ~12.96 m². The same “native 4K” goal on P1.5625 needs 100 cabinets and ~20.25 m². If your room cannot take a 6 m-wide wall, do not force Exact 4K — use a smaller canvas with scaling, or an All-in-One FHD appliance. Always calculate from cabinet resolution, not pitch ÷ size rounded by hand.

Block / Brick use different cabinet maths. All-in-One 135″ / 163″ P1.5625 is fixed 1920 × 1080 — never copy the 100-cabinet count onto an AIO quote.

07 — Pricing

How Much Does a P1.5 LED Display Cost in 2026?

Panel-only USD/m² bands below are from DOIT VISION’s 2026 packaging price table for flat indoor SKUs at this pitch — Block P1.5625 (SMD/GOB) and COB Pro P1.5625. They exclude controllers, structure, shipping, duties and installation. All-in-One, poster and custom curved builds are configured per project.

Packaging (flat indoor, ~P1.5) Panel-only (USD/m²) Notes
SMD / 4-in-1 / GOB (e.g. Block P1.5625) $1,415 – $1,530 Block 1000×500 mm reference; other cabinet sizes are configuration-priced
COB (e.g. COB Pro P1.56) $1,390 – $1,695 Sealed surface and high impact resistance; COB Pro carries CE, EMC and RoHS
All-in-One / poster / custom curve Project-based Chassis, player, structure and geometry require a project configuration
Best-value note from the same price table

At P1.5 the packaging comparison marks COB for long-term TCO — not because SMD is “wrong,” but because sealed surface + lower maintenance often wins over a 5-year contract even when SMD is cheaper on day one. Request like-for-like line items either way.

Add 20–40% on top of panel cost for controller, structure, installation, and commissioning. Budget as a cost structure — panels, control, structure, spares, install, freight. See fine pitch buyer’s guide and 7 hidden numbers in LED quotes. A 20.25 m² Exact-4K COB wall is a mid-to-high five-figure / low six-figure hardware conversation before freight.

08 — Applications

Best-Fit Indoor Applications for P1.5 / P1.56

Strong fit
  • Corporate boardrooms and training rooms with 2–4 m seating — see the conference room solution
  • Lobby / atrium walls where the first row is not handshake-close
  • Control rooms that can sit slightly farther than ultra-fine consoles — or use COB Beta cabinet maths
  • Modular fixed installations using Block or Brick
  • Curved columns at ~P1.5 via Flexible Fixed — confirm radius on flexible LED
  • Freestanding retail or exhibition messaging through a P1.538 poster format
Compare another indoor route
  • For text-heavy viewing below about 1.5–2 m, compare the P1.2 guide
  • For a standard 135″ or 163″ meeting format, compare an All-in-One against a custom wall
  • For a smaller room, use the required canvas size and source resolution before targeting native 4K
  • For a curved feature, submit radius and arc length for a Flexible Fixed engineering check
09 — Proof & RFQ

Real P1.5 Project + RFQ Checklist

Shanghai — 53.76 m² P1.5 COB Beta sand table and wall

This installation combined a 30.72 m² floor display with a 23.04 m² wall across a 9.6 m-wide L-shaped presentation space. The P1.5 COB Beta system used 1,050 modules, three MCTRL4K controllers and approximately 24 million pixels. The project shows why installation geometry and content canvas matter alongside pitch. See the Shanghai P1.5 COB Beta case study.

FAQ

Buyers use “P1.5” for the indoor fine-pitch class around 1.5 mm, while engineering drawings may specify 1.538, 1.56 or 1.5625 mm. These values belong to the same search cluster but create different module and cabinet resolutions. Use the exact pitch, module size and cabinet resolution shown on the approved product drawing for purchasing.

A P1.5-class display supports close viewing from roughly 1.5 m, while many boardrooms, training rooms and lobbies operate comfortably around 2–4 m. Content matters: small text demands more pixels than large video. Test the smallest real text from the closest seat, then compare P1.2 when viewers work inside the 1.5–2 m range.

Choose P1.5 when the closest audience is generally 2–4 m away, the screen is reasonably large and content mixes video with normal presentation text. Choose P1.2 for closer viewing or denser data. Compare both pitches using the same canvas, source content, brightness and cabinet scope so the budget difference reflects useful image detail rather than a label.

Using COB Pro P1.5625 cabinets at 600×337.5 mm and 384×216 pixels each, exact 3840×2160 requires ten cabinets wide by ten high. The resulting 100-cabinet wall measures 6.0×3.375 m, or about 20.25 m². Other series use different cabinet resolutions, so calculate every proposed product from its approved cabinet drawing.

Block or Brick SMD/GOB provides a conventional fixed-wall route with familiar package-level service. COB Pro adds a sealed surface for close viewing, cleaning and contact exposure. Compare both against the same size, brightness, refresh, spare policy and control scope. Their 2026 panel ranges overlap, so installation model, surface use and lifecycle plan should lead the decision.

The 2026 panel-only EXW range is about $1,415–1,530/m² for Block P1.5625 using the 1000×500 mm reference cabinet, and $1,390–1,695/m² for COB Pro P1.5625. Controllers, structure, spares, freight, installation and commissioning typically add 20–40% to a comparable system. All-in-One, poster and curved projects require configuration-specific pricing.

Choose an All-in-One 135″ or 163″ unit for a standard meeting-room footprint, a P1.538 poster for freestanding vertical messaging, or an engineered Flexible Fixed route for a column or curved feature. Submit radius, arc length and service access for curved work. Use COB Beta P1.538 when its 4:3 geometry fits data or special-layout projects.

Send screen width and height, closest viewing distance, smallest text or data element, source resolution, ambient light, installation shape, service access, country and schedule. Ask the supplier to return the exact series, module and cabinet drawings, native resolution, cabinet layout, average and maximum power, control topology, spare quantities, compliance documents and a line-item commercial scope.
