Which EA3DiP1 Pixel Pitch for a Four-Sided 3D Retail Display?

Quick answer

For an EA3DiP1 four-sided retail poster, choose P1.25, P1.56 or P1.86 by the nearest shopper distance and the smallest detail in the content, not by brightness: every configuration shares 600 cd/m², 10,000:1 contrast, 16-bit grayscale and 3,840 Hz. Ask EagerLED to confirm the pitch against the actual viewing zones, then document content preparation, four-screen control and site conditions.

What Changes Between EA3DiP1 P1.25, P1.56 and P1.86?

The EA3DiP1 is a four-sided indoor 3D LED poster display for commercial deployments in shopping malls, exhibitions, theater lobbies and branded retail spaces. Its 680 × 680 × 1,920 mm cabinet uses flexible LED modules to form continuous corners, supports 360° visibility and lists a 170° viewing angle. The buyer selects P1.25, P1.56 or P1.86 pixel pitch for that cabinet.

The pitch choice does not change the published brightness or motion figures. Every EA3DiP1 configuration provides 600 cd/m² brightness, 10,000:1 contrast, 16-bit grayscale and a 3,840 Hz refresh rate, with HDR support. That means P1.25 is not documented as a brighter or smoother option than P1.86; it is a finer pixel density. Use a pixel pitch and viewing distance method to frame the request, then ask the supplier to confirm the chosen pitch for the actual nearest shopper.

The supplied EA3DiP1 passages do not assign different viewing distances to P1.25, P1.56 and P1.86. They describe the series as suitable for close-range indoor viewing and state that detailed imagery and smooth motion come from the shared HDR, brightness, contrast, grayscale and refresh specifications. Because pitch-specific distance is not stated, treat any distance recommendation as a supplier confirmation item rather than a published EA3DiP1 specification.

Use a Documented Indoor LED Wall Rule as a Cross-Check

The EA640F2 indoor LED display page states a working rule for indoor LED walls: allow about 1.5 m of viewing distance for each millimetre of pixel pitch, so a P1.86 wall is comfortable from roughly 2.8 m and a P4 wall from about 6 m. That rule comes from the EA640F2 evidence, not from the EA3DiP1 source, so treat it as a cross-check rather than an EA3DiP1 specification.

Applying that rule as an arithmetic cross-check for the EA3DiP1 pitches gives about 1.9 m for P1.25, 2.3 m for P1.56 and 2.8 m for P1.86. These derived figures are illustrative only and depend on the 1.5 m per millimetre assumption. Ask EagerLED to confirm the pitch against the real nearest viewing position and the smallest text or detail in the retail content before production.

A practical use of the cross-check is to shortlist, not to finalise. If the nearest shopper is likely to stand closer than the cross-check distance for a given pitch, move to a finer pitch or ask the supplier for evidence that the coarse pitch still resolves the content. If the nearest approach is farther, the coarser pitch may remain on the shortlist. The final selection should still be confirmed for the four-sided cabinet and the intended viewing zones.

EA3DiP1 Pitch Decision Cross-Check

Match the Pitch to the Nearest Shopper and Content Detail

Use the closest expected viewer as the primary input. P1.25 is the smallest pitch of the three EA3DiP1 options and is the first option to discuss when shoppers can approach very close or when the content includes small text, logos or fine product detail. P1.56 sits between the two and may suit a retail entrance or aisle where the closest approach is moderate. P1.86 may be adequate when the nearest viewers stay farther back or the content uses large graphics. Check small-text readability with real content at the proposed nearest distance rather than relying on a pitch label alone.

Pitch is only one part of the visual result. The EA3DiP1 creates a naked-eye 3D LED display effect without glasses when content is prepared with the correct perspective for the installation’s viewing zones. A finer pitch cannot substitute for content that is not prepared for the four-sided geometry. Ask who prepares the perspective content, which viewing zones it targets, and whether that preparation is included in the quotation.

Because the cabinet is four-sided, shoppers may approach from several directions. Map the nearest approach on each face, then ask the supplier whether one pitch choice serves the whole cabinet or whether the viewing plan needs a different recommendation. The source lists one pitch selection for the cabinet rather than mixed pitches per face, so any multi-pitch idea should be confirmed as a configuration question.

Four-Screen Control and Remote Management Are Separate From Pitch

The pitch decision does not determine how the four faces are driven. EA3DiP1 supports independent signal input for all four screens, with switching between single-screen and four-screen playback modes. All four faces can show synchronized content, or the configured control system can send independent signals to each screen. Put those playback modes in the EA3DiP1 quote scope so the control configuration is visible.

Remote operation is also a configured-control item. Operators can remotely monitor the display, schedule power-on and power-off times, and manage content wirelessly from a mobile device, subject to the configured control system. Ask the quotation to state which remote functions and control system are included, and whether the intended daily operation depends on independent content per face, synchronized content, or switching between the two.

Site Conditions That Constrain Any Pitch Choice

Regardless of pitch, the EA3DiP1 is a 125 kg indoor unit with a base that includes quiet universal caster wheels for repositioning between indoor locations. The source advises confirming viewing distance, content perspective, floor loading, power, signal routing and maintenance access before production. For a retail site, those checks should be completed alongside the pitch selection because they can affect where the cabinet can stand and how it is serviced.

The cabinet is designed for close-range indoor commercial installations rather than outdoor billboard deployment, and front-service access lets technicians inspect, maintain or replace modules without rear service clearance. Use a viewing angle specification guide when checking that the 170° viewing angle covers the shopper approaches you care about, then confirm the content perspective and any wall, fixture or pedestrian route near the intended position.

A Practical Pitch Selection Sequence for a Retail Rollout

Start by mapping the nearest shopper distance on each of the four faces and listing the smallest text or product detail that must remain readable. Shortlist P1.25, P1.56 or P1.86 with the supplier using the viewing distance cross-check. Next, confirm the naked-eye 3D content preparation: who supplies it, which viewing zones it targets, and how it is quoted. Then confirm the four-screen control mode and remote management scope. Finally, confirm floor loading, power, signal routing and maintenance access for the exact position.

Common mistakes follow from the documented scope. Do not choose P1.25 over P1.86 because you expect higher brightness; the series shares 600 cd/m², 10,000:1 contrast, 16-bit grayscale and 3,840 Hz. Do not assume the 3D effect is created by the cabinet alone; it depends on correctly prepared perspective content for the viewing zones. Do not plan the unit as an outdoor billboard, and do not ignore the 125 kg weight, floor loading or front-service route.

Site and Control Evidence to Request

Illustrative calculation: 1.25 × 1.5 = 1.875 m. Applies the EA640F2 indoor LED wall working rule of 1.5 m per millimetre of pixel pitch as a cross-check only; not an EA3DiP1 specification.

EA3DiP1 P1.56 cross-check viewing distance

Illustrative calculation: 1.56 × 1.5 = 2.34 m. Applies the EA640F2 indoor LED wall working rule of 1.5 m per millimetre of pixel pitch as a cross-check only; not an EA3DiP1 specification.

EA3DiP1 P1.86 cross-check viewing distance

Illustrative calculation: 1.86 × 1.5 = 2.79 m. Applies the EA640F2 indoor LED wall working rule of 1.5 m per millimetre of pixel pitch as a cross-check only; not an EA3DiP1 specification.

Buyer checklist

• Map the nearest shopper distance on all four faces before choosing P1.25, P1.56 or P1.86.
• List the smallest text or product detail that must remain readable at that nearest distance.
• Ask the supplier to confirm the EA3DiP1 pitch against the actual viewing zones using the documented indoor LED wall cross-check.
• Confirm who prepares the naked-eye 3D perspective content and which viewing zones it targets.
• Put four-screen playback modes and remote management scope in the quotation, subject to the configured control system.
• Confirm 125 kg handling, caster-wheel base, floor loading, power, signal routing and front-service access before production.

Frequently asked questions

Does EA3DiP1 P1.25 have higher brightness than P1.86?

No. The source states every EA3DiP1 configuration provides 600 cd/m² brightness, 10,000:1 contrast, 16-bit grayscale and a 3,840 Hz refresh rate. The three pitches differ in pixel density, not in those published figures. Choose pitch by nearest shopper distance and content detail, then confirm the selection with EagerLED.

How do I use viewing distance to choose an EA3DiP1 pitch?

The EA3DiP1 source does not state pitch-specific viewing distances. The EA640F2 indoor LED display page gives a working rule for indoor LED walls of about 1.5 m per millimetre of pixel pitch, so a cross-check suggests roughly 1.9 m for P1.25, 2.3 m for P1.56 and 2.8 m for P1.86. Use that only as a cross-check and ask EagerLED to confirm the pitch for the actual nearest shopper and content.

Does the EA3DiP1 pixel pitch create the naked-eye 3D effect by itself?

No. The source states the naked-eye 3D effect without glasses is created when content is prepared with the correct perspective for the installation’s viewing zones, together with the continuous corners and 170° viewing angle. Ask the supplier to confirm whether content preparation is included in or separate from the quotation.

What site conditions should I confirm for any EA3DiP1 pitch?

Confirm viewing distance, content perspective, floor loading, power, signal routing and maintenance access before production. The EA3DiP1 is a 125 kg indoor unit with caster wheels and front-service access, so check the floor, route, power and signal arrangement for each intended indoor location.

Is EA3DiP1 suitable for outdoor retail use?

The source describes EA3DiP1 as a four-sided indoor 3D LED poster display for close-range commercial installations rather than outdoor billboard deployment. If the project requires outdoor exposure, treat that as a different product and site-engineering question rather than assuming the indoor EA3DiP1 cabinet is suitable.
