EA640F2 Fixed Indoor Video Wall Checks
Provide the usable wall width and height, the closest viewing position and representative content such as presentation slides, product images or live video. Confirm the cabinet grid and total pixel map before selecting the processor and deciding whether the proposed pitch supports the required text size.
- Front service: agree the removal clearance, service tools, cable access and maintenance procedure; front access does not remove the need to plan safe servicing.
- SMD or COB: compare the exact datasheets, surface construction, brightness, refresh and repair scope. Do not assume modules from the two configurations are interchangeable.
- Room operation: define daytime and dim-room brightness settings and provide the camera workflow if the screen will be filmed.
- Installation scope: list the cabinets, processor, receiving cards, power equipment, spares and local support structure separately.

Front-Service Access
Because modules and key internal components are accessible from the front, technicians can service the display without reserving a rear maintenance corridor. As a result, the EA640F2 is practical for wall-mounted installations and other spaces where depth is limited.
Indoor LED Display Screen Image Quality
Pixel-pitch options start at P1.25, with pixel density up to 640,000 pixels/m². In addition, a refresh rate of at least 3840 Hz supports smooth video playback and helps reduce visible scan lines when the screen is filmed. Depending on pixel pitch, SMD model brightness ranges from 600 to 800 cd/m².
Organized Internal Layout
An adapter-board architecture reduces exposed power and data cabling inside the cabinet. As a result, the cleaner layout simplifies connections and leaves fewer loose cables to manage during installation and maintenance.
Standard 320 × 160 mm Modules
Every SMD and COB configuration uses 320 × 160 mm modules. Therefore, one module format across the series simplifies cabinet planning, spare-parts stocking, installation, and routine module replacement.
4:3 Cabinet Format
The 640 × 480 mm cabinet has a native 4:3 aspect ratio. For example, arranging cabinets in a 4-by-3 grid creates a 16:9 canvas without changing the cabinet size.
140° Wide Viewing Angle
A 140° viewing angle keeps content visible to audiences seated or standing away from the center line. As a result, the cabinet suits conference rooms, retail spaces, broadcast studios, control rooms, and other wide indoor viewing areas.

Frequently Asked Questions
What is the EA640F2 indoor LED display?
The EA640F2 is a front-service indoor LED display cabinet for fixed video-wall installations. Each cabinet measures 640 × 480 mm, weighs 7.5 kg, and supports both SMD and flip-chip COB configurations.
Which pixel pitches are available for the EA640F2?
SMD models are available in P1.25, P1.53, P1.86, P2, P2.5, P3.076, and P4. Flip-chip COB models are available in P1.25, P1.53, and P1.86.
Can the EA640F2 be serviced from the front?
Yes. Modules and key internal components are accessible from the front, which reduces the need for rear maintenance space and suits wall-mounted indoor installations.
What module size does the cabinet use?
All listed SMD and COB versions use 320 × 160 mm LED modules. The common module format simplifies cabinet planning and spare-module management across the EA640F2 series.
What are the brightness and refresh-rate specifications?
SMD models provide 600 to 800 cd/m² brightness, depending on pixel pitch. COB models are rated at 600 cd/m². All listed versions have a refresh rate of at least 3840 Hz.
What viewing angle does the EA640F2 provide?
The specified viewing angle is 140°. This helps audiences see content clearly from a wider range of positions in conference rooms, retail spaces, studios, control rooms, and similar indoor venues.
How does the 4:3 cabinet ratio support a 16:9 video wall?
Each 640 × 480 mm cabinet has a 4:3 aspect ratio. Arranging cabinets in a 4-by-3 grid creates an overall 16:9 canvas, while other cabinet combinations can support different screen shapes.
How should I choose the right pixel pitch?
Choose a smaller pixel pitch for closer viewing and higher detail, or a larger pitch for longer viewing distances and a lower project cost. Share the screen size, viewing distance, installation environment, and content type for a model recommendation and quotation.
