Planning an Indoor LED Video Wall for a Car Dealership Showroom

Quick answer

For a car dealership showroom, plan the wall around the closest customer viewing position and the area behind or beside vehicles. Match pitch to that distance: EA250WH5 documents P1.25–P1.95 GOB for about 2 m and P2.5–P3.91 for about 3 m and beyond; EA640H1 documents P1.25–P1.86 for about 2 to 3 m and P2 or P2.5 for roughly 3 to 4 m. Confirm brightness under showroom lighting and plan front service.

Start with the showroom layout and vehicle sightlines

Begin with measured positions rather than a screen size. Mark the planned wall behind or beside vehicle displays, the closest point where a customer will stand, the farthest point, side aisles, columns and glass. S3 advises defining the active screen width, height, aspect ratio and final pixel resolution before content production begins. S4 states that modular LED cabinets can be configured for different wall dimensions and aspect ratios, and that the final design must account for viewing distance, image resolution, structural support, ventilation, power, signal routing and maintenance access. Those are planning inputs, not supplier confirmations.

Glass is a site condition that changes the screen position and the content test. S3 states that an LED wall produces light directly and does not require a projection surface, which can improve visibility in rooms with ambient light, but the right choice still depends on viewing distance, room lighting, mounting structure, camera use, maintenance access and budget. S4 advises comparing candidate systems in the actual lighting conditions and at the intended operating brightness. For a dealership, that means testing the proposed wall position with representative vehicle imagery, text and showroom lighting rather than relying on a headline brightness figure.

Match pixel pitch to the closest customer view and smallest text

Use the closest normal viewing position, the smallest text or detail customers must read, and camera distance to frame the pitch choice. EA250WH5 documents seven pitches from P1.25 GOB to P3.91. EagerLED places P1.25, P1.56 and P1.95 GOB for lobbies, meeting rooms and control rooms watched from about 2 m, and P2.5 to P3.91 for retail and larger rooms viewed from about 3 m and beyond. EA640H1 documents P1.25 to P2.5, with P1.25 to P1.86 for rooms watched from about 2 to 3 m and P2 or P2.5 for roughly 3 to 4 m. Treat those as model-specific scopes, not universal dealership rules. Use a pixel pitch and viewing distance method and then request a small-text test at the closest customer position.

If the closest customer is very close or the content includes fine vehicle detail, a fine-pitch COB option may be relevant. S3 lists EA600COB3 as a flip-chip COB indoor screen with a 600 × 337.5 mm 16:9 cabinet, 30 mm thickness, 4.1 kg cabinet weight and six pixel pitches from P0.62 to P1.87. S4 notes that fine-pitch LED products use different package and module architectures, including COB, and advises comparing pixel pitch, surface durability, repair method, uniformity, contrast, cabinet dimensions and calibration workflow for the specific model rather than applying one technology label to every product. If the documented pitch bands for EA250WH5 or EA640H1 do not fit the closest viewer, treat that as a separate model-selection question.

Showroom LED wall decisions and evidence to request

Confirm brightness, contrast and surface for showroom glass and light

Brightness should be selected for the exact pitch, ambient light, content and camera requirements, not as a series headline. EA250WH5 lists 600 cd/m² on P1.25 and P1.56 and 750 cd/m² from P1.95 to P3.91, with a 160° viewing angle. EA640H1 lists 600 cd/m² on P1.25 to P1.86, 700 cd/m² on P2 and 800 cd/m² on P2.5, with a 140° viewing angle. S4 advises confirming the specified brightness, contrast, colour calibration and camera test results for the selected configuration before ordering. Record a brightness acceptance setting for the actual showroom lighting.

Surface choice is separate from pitch. EA250WH5 uses GOB on its P1.25 pitch and offers pitches up to P3.91; EA640H1 uses GOB on P1.25, P1.53, P1.86 and P2 models, while its P2.5 model uses a standard SMD2020 module. S2 states that GOB fills the gaps between LEDs with a clear protective compound, making the module surface more resistant to knocks, dust and cleaning. EA600COB3 is a flip-chip COB fine-pitch alternative. S4 advises comparing surface durability, repair method, uniformity, contrast and calibration workflow at model level, and requesting a product-level data sheet and sample evaluation for any claim about contrast, blue-light performance, curvature, transparency or interaction. That is the right frame for a showroom where glass, vehicle paint and cleaning touchpoints matter.

Plan front service, installation and power for the showroom wall

A showroom wall often sits close to a finished surface, so front service is a practical planning point. EA250WH5 modules, power supplies and control components are reachable from the front with a suction tool, so no maintenance aisle is needed behind the wall. EA640H1 modules are removed from the viewing side with a vacuum service tool, so no rear service corridor is needed. EA600COB3 also documents full front service and a cable-free HUB connection. Confirm the front clearance, removal tool, spare modules and access route for the installed position, and put that in a service-response agreement.

Cabinet depth and mounting affect the showroom design. EA250WH5 is a 30 mm ultra-thin indoor cabinet family with six cabinet sizes from 500 × 250 mm to 1000 × 500 mm, all using a 250 × 250 mm module; it supports wall-mounted, suspended or column installation and right-angle or column configurations. EA640H1 is 48 mm deep and 6.7 kg per cabinet, with die-cast aluminum cabinets joined by quick locks; its source advises allowing extra depth for structure and ventilation. EA640H1 lists AC 100–240 V, 50–60 Hz, average consumption of 100 W/m² and maximum consumption of 300 W/m² across all five pitches, and advises sizing the supply, cabling and any UPS on the maximum figure. Request EA250WH5 power consumption for the exact pitch and wall area.

Compare EA250WH5, EA640H1 and a COB fine-pitch option

EA250WH5 is the shallow-cabinet route: 30 mm deep, front service with suction tool, six cabinet formats, seven pitches from P1.25 GOB to P3.91, and documented wall, suspended or column installation with right-angle and column configurations. Choose it when the showroom wall is shallow, the cabinet grid fits the wall, and the documented pitch band fits the closest customer. The trade-off is that the larger pitch range includes P2.5 to P3.91 for about 3 m and beyond, so a very close customer position may push you to P1.25 to P1.95 GOB or to a different model.

EA640H1 is the 640 × 480 mm front-service route: 48 mm deep, 6.7 kg per cabinet, P1.25 to P2.5, GOB on P1.25 to P2, and documented brightness of 600, 700 or 800 cd/m² depending on pitch. Its 4:3 cabinet can be planned into 4:3 or 16:9 walls, and a 12-cabinet 4-wide, 3-high array builds a 2,560 × 1,440 mm 16:9 wall. Choose it when the larger cabinet format suits the wall and the documented pitch and brightness fit. If the closest viewer needs a finer pitch or a native 16:9 cabinet, S3 lists EA600COB3 with six pitches from P0.62 to P1.87 in a 600 × 337.5 mm 16:9 cabinet.

Coordinate content, camera and signal with glass and lighting

Content should be planned for the wall’s aspect ratio and the smallest text or graphic customers must read. S3 advises defining active width, height, aspect ratio and final pixel resolution before content production begins, and notes that standard cabinet formats such as 640 × 480 mm or 600 × 337.5 mm can simplify 4:3 or 16:9 wall planning. S4 states that image quality depends on pixel pitch, native canvas resolution, processor scaling, calibration and viewing distance, and advises validating the complete signal path. For a dealership, separate vehicle imagery, price or offer text, brand video and any live camera feed into zones so the smallest text is not squeezed into a wide showroom view.

If the wall will appear on camera or be filmed for social media, refresh rate and grayscale are part of the specification. EA250WH5 and EA640H1 document at least 3,840 Hz refresh; EA250WH5 offers 14/16-bit grayscale and EA640H1 14-bit grayscale. S1 states that at least 3,840 Hz refresh keeps content stable on camera. S4 advises testing on camera and confirming service procedures fit the site. Request a camera test at the planned frame rate, shutter, brightness and camera position rather than treating the refresh figure alone as acceptance.

Scope the quotation without invented prices

Price depends on pixel pitch, wall size, cabinet quantity, control system, spare modules and shipping, so each wall is quoted per project. S3 advises a complete proposal to separate the LED cabinets, video controller, mounting structure, power and signal distribution, spare modules, freight, installation and commissioning. Ask each supplier to state the proposed pixel pitch, active resolution, typical and maximum power, cabinet quantity, service method and warranty scope. Compare offers on the same rows with a compare LED screen quotes method rather than a single total.

For a dealership, include the showroom-specific items that change the build: front-service clearance, cabinet format, column or right-angle work, brightness and calibration acceptance, spare modules, and any camera test. Keep those lines separate so two offers are compared on identical inclusions. This is our purchasing advice, not a manufacturer requirement. If a supplier cannot confirm the quoted pitch, cabinet map, service route or power figure for the exact model, treat the quote as provisional.

Showroom scenarios and what to confirm first

EA640H1 wall width for four cabinets wide

Illustrative calculation: 4 × 640 = 2560 mm. Illustrative four-cabinet-wide array using the documented 640 mm cabinet width; this is an arithmetic example, not a recommended wall size.

EA640H1 wall height for three cabinets high

Illustrative calculation: 3 × 480 = 1440 mm. Illustrative three-cabinet-high array using the documented 480 mm cabinet height; this is an arithmetic example, not a recommended wall size.

EA640H1 12-cabinet wall weight

Illustrative calculation: 12 × 6.7 = 80.4 kg. Illustrative 12-cabinet 2,560 × 1,440 mm wall using the documented 6.7 kg per cabinet weight; 80.4 kg rounds to about 80 kg and excludes the mounting frame, controller and cables.

Buyer checklist

• Measure the closest customer position, farthest view, side aisles, glass, columns and vehicle display positions before comparing models.
• Define active width, height, aspect ratio and resolution before content production begins.
• Request pitch-specific brightness, viewing angle, refresh and grayscale for the exact model and pitch.
• Confirm the front-service tool, front clearance, installed assembly depth and spare-module plan for the exact position.
• Confirm power and ventilation for the exact model; use the maximum consumption figure where documented.
• Ask for a sample evaluation under showroom lighting for reflection or glare, and a camera test if the wall will appear on camera.

Frequently asked questions

How do I choose pixel pitch for a car dealership showroom LED wall?

Start with the closest customer viewing position and the smallest text or vehicle detail that must be readable. EA250WH5 documents P1.25, P1.56 and P1.95 GOB for rooms watched from about 2 m, and P2.5 to P3.91 for rooms viewed from about 3 m and beyond. EA640H1 documents P1.25 to P1.86 for about 2 to 3 m and P2 or P2.5 for roughly 3 to 4 m. Treat these as model-specific scopes and request a small-text test at the actual closest position.

Can an indoor LED wall reduce glass reflections in a showroom?

Treat reflection as a site condition. S3 states that an LED wall produces light directly and does not require a projection surface, which can improve visibility in rooms with ambient light, but the right choice still depends on viewing distance, room lighting, mounting structure, camera use, maintenance access and budget. S4 advises comparing systems in the actual lighting conditions and at the intended operating brightness. Ask for a sample evaluation for the exact surface and screen position.

Should we choose GOB or COB for a dealership showroom?

EA250WH5 uses GOB on P1.25 and offers pitches up to P3.91. EA640H1 uses GOB on P1.25, P1.53, P1.86 and P2, while P2.5 uses standard SMD2020. EA600COB3 is a flip-chip COB fine-pitch indoor screen with six pitches from P0.62 to P1.87 in a 600 × 337.5 mm 16:9 cabinet. S2 states GOB fills the gaps between LEDs with a clear protective compound, making the surface more resistant to knocks, dust and cleaning. S4 advises comparing surface durability, repair method, uniformity, contrast and calibration at model level, so request product-level evidence and a sample evaluation rather than choosing by label alone.

What brightness should a showroom LED wall use?

Select brightness for the exact pitch, showroom lighting, content and camera requirements. EA250WH5 lists 600 cd/m² on P1.25 and P1.56 and 750 cd/m² from P1.95 to P3.91. EA640H1 lists 600 cd/m² on P1.25 to P1.86, 700 cd/m² on P2 and 800 cd/m² on P2.5. S4 advises confirming brightness, contrast, colour calibration and camera test results for the selected configuration before ordering, and comparing in the actual lighting conditions at operating brightness.

How much rear clearance does a showroom LED wall need?

EA250WH5 and EA640H1 are both front-service indoor walls. EA250WH5 modules, power supplies and control components are reachable from the front with a suction tool, so no maintenance aisle is needed behind the wall. EA640H1 modules are removed from the viewing side with a vacuum service tool, so no rear service corridor is needed. EA640H1 evidence also advises allowing extra depth for structure and ventilation. Confirm the front clearance, removal tool and installed assembly depth for the exact position.

What should a dealership include in the LED wall quotation?

Ask for separate lines for LED cabinets, video controller, mounting structure, power and signal distribution, spare modules, freight, installation and commissioning. Ask the supplier to state the proposed pixel pitch, active resolution, typical and maximum power, cabinet quantity, service method and warranty scope. Price depends on pixel pitch, wall size, cabinet quantity, control system, spare modules and shipping, so it is quoted per project rather than as a fixed list price.
