Front and Rear Service LED Module Selection
Front and rear service LED modules let display contractors plan replacement access from either side of a compatible cabinet. Choose the full module model, physical size, pixel map, scan mode and connector layout before ordering; a matching pixel-pitch label alone does not establish spare-part compatibility.
- Published outdoor module families: 320 × 320, 250 × 250 and 320 × 160 mm.
- Front/rear service depends on a compatible cabinet and the installed access route.
- SMD and DIP configurations have different LED packages and published brightness.
- Confirm the chosen model’s protection rating, compliance documents and written warranty terms.

| Published example | Module size | Pixel map | Scan mode | Brightness |
|---|---|---|---|---|
| P4-O10S-1921-320x320F | 320 × 320 mm | 80 × 80 | 1/10 | 5500 nits |
| P3.91-O8S-1921-250x250F | 250 × 250 mm | 64 × 64 | 1/8 | 6000 nits |
| P4-O10S-1921-320x160F | 320 × 160 mm | 80 × 40 | 1/10 | 5500 nits |
These examples come from the published module tables and are not interchangeable replacement recommendations. The two P4 examples share pitch and scan mode but have different physical sizes and pixel maps; verify the cabinet opening, fastening and connector arrangement.
For an existing LED wall, send a readable module label, front and rear photographs, module measurements, pixel resolution, scan mode and receiving-card details. Confirm voltage, pinout and calibration with the supplier before fitting replacement stock.
Dual-side maintenance describes an access design, not one universal environmental rating. The selected module, seals, cabinet, cable entries and installation determine the applicable protection arrangement. Request the model-specific datasheet and supporting documents for the project.
Purchase questions
Can I buy a spare module using only its pitch and dimensions?
Use the complete model and hardware specification. LED package, driver configuration, scan mode, voltage, connector orientation and calibration can differ even where pitch and external dimensions match.
Does a dual-service module make any cabinet front-serviceable?
Confirm the module fastening system and a safe removal route in the actual cabinet. Power supplies, receiving cards and cabling may have different access requirements from the LED module itself.
What should a front and rear service LED module quote include?
List exact module models, quantities and spare batches, cabinet interfaces, control compatibility, power connections and delivery scope. Ask for current model-specific compliance documents and written warranty coverage in the order documentation.

Dual Service LED Screen Panel
Superior LED Chips
Published chip brands include Nationstar and Kinglight. Confirm the LED package, chip option, driving configuration and calibration requirements for the exact module being ordered.
SMD 3 in 1 LED
The published tables list SMD1921, SMD2727, SMD3535 and DIP configurations with model-specific brightness values. Select the complete LED package and driving specification from the corresponding parameter row.
Easy Assembling
Dual service LED modules can be easily replaced or removed from the front or back by just one person. Screwless design makes it easier to quickly mount the module to the cabinet.
Dual-Mode Maintenance
Dual-mode maintenance (Front and Rear) LED display panel saves the maintenance space and time, being compatible with hard installation conditions.
