Quick answer
For an indoor adoption board, choose an indoor close-view LED poster rather than an outdoor billboard. EagerLED EA1920iP4 documents P1.25–P2.5, 600–800 cd/m², GOB modules and cloud updates; EA3DiP1 documents P1.25–P1.86, 600 cd/m² and front service. Confirm small-text legibility at planned viewing positions, cleaning, update roles and a local fallback in writing.

Choose an Indoor Poster Format Before the Adoption Board Content
Adoption boards often sit in a lobby, corridor or meet-and-greet area where visitors stand close. The EA1920iP4 is documented as a 640×1920 mm foldable LED poster display built for double-sided indoor advertising, with GOB LED module design, P1.25, P1.53, P1.86, P2 or P2.5 pixel pitch, SMD/GOB or flip-chip COB modules, 600–800 cd/m² brightness and at least 3840 Hz refresh. That makes it a candidate for a double-sided adoption listing board where visitors approach from one or two directions.
If visitors approach from several directions in an open lobby, the EA3DiP1 is documented as a four-sided indoor 3D LED poster with a 680 × 680 × 1,920 mm cabinet, flexible LED modules for continuous corners, 360° visibility and a 170° viewing angle. It is intended for indoor commercial spaces such as mall atriums, retail entrances, exhibition stands and theater lobbies, so treat it as a possible freestanding adoption feature only where its four-sided format fits the floor plan.
Do not assume an outdoor poster suits an indoor adoption lobby. The EA1920OP2 is documented as an outdoor foldable poster with IP65 front and rear, 5,000 cd/m² brightness and rear service, so it is a different application scope. For an outdoor adoption event, confirm the exact outdoor configuration; for an indoor shelter board, start with the indoor models and their documented indoor use.
Pixel Pitch and Brightness Planning for the Adoption Board
The supplied evidence documents pixel pitch ranges for the two indoor posters: EA1920iP4 offers P1.25 to P2.5, and EA3DiP1 offers P1.25, P1.56 and P1.86. To plan, use a pixel pitch and viewing distance method as a starting point, but confirm small-text legibility with the supplier at the actual positions using real pet names, ages, status labels and adoption steps. We recommend testing actual content rather than selecting by screen size alone.
Brightness is a separate decision. EA1920iP4 documents 600–800 cd/m² across its available configurations, and EA3DiP1 documents 600 cd/m² for every configuration, with 10,000:1 contrast, 16-bit grayscale and 3,840 Hz refresh. For a shelter lobby, ask for the proposed operating brightness preset under the actual lighting and check that the adoption text remains comfortable rather than glaring at the closest standing position.
Low-glare planning is not a single specification in the supplied evidence. Ask the supplier to confirm the quoted brightness setting, dimming range if offered, and whether the control system can schedule day and evening levels for the exact model. Treat that as a written configuration question rather than assuming a headline brightness suits every hour.
Animal Shelter Adoption Board Decisions and Evidence to Request
| Decision | Evidence to request |
|---|---|
| Double-sided indoor listing board | Confirm EA1920iP4 640×1920 mm cabinet, P1.25–P2.5, 600–800 cd/m², GOB or flip-chip COB modules and the update route for the exact configuration. |
| Four-sided lobby feature | Confirm EA3DiP1 680 × 680 × 1,920 mm cabinet, P1.25–P1.86, 600 cd/m², 10,000:1 contrast, 16-bit grayscale, 3,840 Hz refresh, front service and independent four-screen playback. |
| Closest visitor and smallest pet text | Request a small-text test at the closest standing position using real pet names, ages, status labels and adoption steps; match it to the quoted pitch. |
| Update roles and fallback | Define who prepares, approves and publishes each profile; compare documented cloud updates with local USB or HDMI playback for the exact model. |
| Protected surface and cleaning | Confirm whether the quoted EA1920iP4 module is GOB or flip-chip COB and request a written cleaning method for that exact surface. |
| Service route | For EA3DiP1, confirm front-service access, removal tool and clearance; for EA1920iP4, confirm the module service route because the supplied passage documents GOB modules but not front service. |
Plan a Protected Module Surface and Cleaning Method
The EA1920iP4 is documented with a GOB LED module design, and its 320×160 mm modules are available as SMD/GOB, with flip-chip COB options at P1.25, P1.53 and P1.86. GOB is a documented module surface choice for that model; it does not by itself establish a shelter cleaning procedure, chemical resistance or damage resistance beyond the source.
For an adoption board touched by volunteers, visitors or cleaning staff, request a written cleaning method for the exact module surface, including approved cloths, cleaners and power-down steps before routine cleaning. The supplied evidence documents the GOB design but not an adoption-board cleaning schedule, so put that item in the quotation and handover scope rather than inferring it.
Design Update Roles and a Local Fallback for Failed Updates
EA1920iP4 documents smart cloud content management that can update from an iPad, iPhone, Android phone, PC or laptop through Wi-Fi or USB, with real-time playback and multi-platform publishing. For an adoption board, that supports a workflow where an approved volunteer or staff member publishes pet profiles from a phone or desk computer, but the shelter must define who prepares, who approves and who publishes each listing.
For a four-sided EA3DiP1, remote content management includes independent signal input for all four screens, switching between single-screen and four-screen playback, remote monitoring, scheduled power-on and power-off, and wireless content management from a mobile device subject to the configured control system. Use a content schedule planning method so adoption profiles, donation appeals and event notices do not compete for the same zone.
Plan a fallback for when a cloud or network update fails. EA1920iP4 documents USB 3.0, HDMI, Wi-Fi, SIM and Ethernet connections, so a local USB or HDMI source can be part of the update plan if the configured system supports it. Compare cloud content management vs USB playback as separate operating routes and ask what happens to the last published adoption profile if the primary route is unavailable.
Match Service Access, Mobility and Quote Lines to the Shelter Space
EA1920iP4 documents a 60 mm cabinet, 43.5 kg total weight, four caster wheels, quick-lock multi-screen splicing, built-in speakers and one-person folding into a flight case. Those features suit an adoption board that may move between lobby positions or event days, but the source does not document a front-service method for that model, so confirm the module service route for the exact unit.
EA3DiP1 documents front-service access, caster wheels and a 125 kg unit, allowing technicians to inspect, maintain or replace modules without rear service clearance and venue teams to reposition it indoors. For a shelter with finished walls or limited rear access, that documented front-service access is relevant, but still record the removal tool, clearance and spare-module match in a service-response agreement.
Ask for an itemised quote that separates the display, control, mounting or base, power and data, content templates, spare modules, freight and commissioning. Because the supplied evidence does not quote a price or an adoption-board package, treat every total as project-specific and compare offers on the same pitch, cabinet quantity and service scope.
Adoption Board Scenarios and What to Confirm First
| Scenario | What to confirm |
|---|---|
| Visitors approach from one or two directions | Confirm the EA1920iP4 double-sided indoor poster format, quoted pitch, brightness preset and update workflow for the lobby position. |
| Visitors can approach from all four sides | Confirm the EA3DiP1 four-sided format, floor loading, power, signal routing and maintenance access for the open floor plan. |
| Volunteers update from phones or a desk PC | Confirm cloud management updates from iPad, iPhone, Android, PC or laptop through Wi-Fi or USB for EA1920iP4, and define approval roles. |
| Primary cloud or network update fails | Confirm local USB or HDMI fallback on EA1920iP4 and state what last-published adoption content remains visible. |
| Adoption event moves outdoors | Do not use EA1920iP4 or EA3DiP1 as weather-rated evidence; confirm an outdoor-rated configuration such as EA1920OP2 for the exact outdoor event scope. |
| Fixed position has no rear access | Confirm front service on EA3DiP1, which documents front-service access; confirm the service route for EA1920iP4 separately. |
Buyer checklist
- Measure closest visitor, side positions and smallest pet name or status text; request a small-text test with real adoption content.
- Confirm quoted pitch, brightness preset, refresh rate and module surface for the exact indoor model.
- Define prepare, approve and publish roles for adoption profiles, and test the update path on the actual phone or PC.
- Agree a local USB or HDMI fallback and state what content remains visible if the primary update route fails.
- Confirm the written cleaning method for the exact GOB or flip-chip COB module surface.
- If the board will be outdoors, confirm an outdoor-rated model and the IP rating for each exposed face; do not use indoor poster evidence.
Frequently asked questions
Which EagerLED indoor display suits an animal shelter adoption board?
The EA1920iP4 is documented as a 640×1920 mm double-sided indoor foldable poster with P1.25–P2.5, 600–800 cd/m², GOB module design and cloud updates. The EA3DiP1 is documented as a four-sided indoor poster with P1.25–P1.86, 600 cd/m², front-service access and independent four-screen playback. Neither source documents adoption-specific software, so treat content and roles as project scope.
What pixel pitch should an adoption board use?
The supplied evidence documents EA1920iP4 P1.25–P2.5 and EA3DiP1 P1.25–P1.86. To choose, ask the supplier to confirm small-text legibility at the planned viewing positions with real pet names, ages, status labels and adoption steps. We recommend testing actual content rather than selecting by screen size alone.
How should volunteers update an animal shelter adoption board?
EA1920iP4 documents smart cloud management that updates from an iPad, iPhone, Android phone, PC or laptop through Wi-Fi or USB, with real-time playback and multi-platform publishing. EA3DiP1 documents remote content management from a mobile device, subject to the configured control system. Define who prepares, approves and publishes each profile before the display goes live.
What should happen if an adoption board update fails?
EA1920iP4 documents USB 3.0, HDMI, Wi-Fi, SIM and Ethernet connections, so a local USB or HDMI playback route can be part of the fallback plan if the configured system supports it. Ask the supplier what happens to the last published adoption profile when the primary update route is unavailable, and confirm the fallback as a written operating procedure.
Does a GOB module surface mean the adoption board can be cleaned with any product?
No. EA1920iP4 documents a GOB LED module design and SMD/GOB modules, with flip-chip COB options at P1.25, P1.53 and P1.86. The supplied evidence does not document a cleaning product, chemical resistance or shelter cleaning procedure. Request a written cleaning method for the exact quoted module surface before volunteer or cleaning staff use it.
Can an indoor adoption poster be used outdoors at an adoption event?
Do not assume it can. EA1920iP4 is documented for double-sided indoor advertising, while EA1920OP2 is documented as an outdoor foldable poster with IP65 protection on the front and rear, 5,000 cd/m² brightness and rear service access. If the adoption event is outdoors, confirm the exact outdoor-rated configuration rather than using indoor poster evidence.
