LED Module 320×160: How Module Size Affects Cabinet Design

Buyers compare pitch and cabinet size, then treat the module as an internal detail. In practice the module size controls replacement cost, spare inventory and how evenly the cabinet can be serviced.

Why 320×160 became standard

It divides cleanly into the common cabinet formats: three modules across a 960 mm cabinet, two across a 640 mm cabinet, and two across a 500 mm rental cabinet with a different module size. Standardising on one module size across a product line reduces tooling cost and makes spare stock simpler for distributors.

Module size and cabinet geometry

A 960×960 mm cabinet in 320×160 modules holds 3 × 6 = 18 modules. A 640×480 mm indoor cabinet holds 2 × 3 = 6. The module count per cabinet drives the number of receiving card ports, the data topology and the number of screws a technician removes to reach a failed part.

Spares and service planning

Module size sets the spare-parts unit. For a 30 m² outdoor wall with 18 modules per cabinet, 5% spare modules is about 17 units — a small box compared with a spare cabinet. Distributors should stock modules, receiving cards and power supplies in proportion to the installed base, not to the order value.

Pitch options on the same module

The same 320×160 module footprint can carry different pitches by changing the LED density: P4, P5, P6.67, P8 and P10 all use the same board size with different pixel counts. That is convenient for manufacturing, but it means two cabinets that look identical from outside may use different modules inside. Always match by batch and part number when expanding a wall.

Module design details that change service cost

Two modules with the same 320×160 footprint can differ in ways that matter after installation: the number of screws, whether the mask is integrated or separate, the connector type, and whether the module can be removed without touching neighbouring modules. A module that requires removing four screws and unplugging two cables is a five-minute job; one that requires lifting the adjacent module turns a single failure into a two-person repair.

Ask for a service demonstration, not a drawing. On a 30 m² wall at 8 m height, the difference between a five-minute and a twenty-minute swap is the difference between a maintenance visit and a crane booking.

Matching modules across orders

LEDs are binned by brightness and colour during production. A module supplied six months later may be from a different bin and show a visible patch on a white screen. Distributors should record the batch number and ask the supplier how long the same bin can be held for expansion orders. If the answer is “we cannot guarantee”, plan to buy the spare modules with the original order — it is cheaper than replacing a section later.

How to calculate module count before ordering

Module count equals cabinets × modules per cabinet. For an outdoor wall of 9 × 4 m: 9 columns of 960 mm and 4 rows gives 36 cabinets, each with 18 modules, so 648 modules. Add 3–5% spares and you have a purchasing number that can be checked against the invoice.

Spare modules or spare cabinets?

Most buyers choose modules because they are cheaper and cover the common failure. A small number of spare cabinets makes sense for rental fleets and for sites where a damaged cabinet would leave a visible hole. The decision should follow the service model: if a technician can swap a module on site, modules are enough; if the cabinet itself can be struck by a vehicle or a ball, keep one or two cabinets.
