What are the differences between indoor LED displays with cabinets and cabinet-free ones?

1. Structure & Thickness

• With cabinets: Supported by sheet metal or die-cast aluminum frames, thicker and require more space behind the wall.
• Cabinet-free: Bare modules matched with simple back strips and keels, ultra-thin, wall-hung with almost no rear space occupied.

2. Maintenance Method

• With cabinets: Mostly rear maintenance, a service passage must be reserved behind the screen; front-access cabinets cost extra.
• Cabinet-free: Full front maintenance. No rear space needed; modules can be replaced directly from the front side.

3. Transportation & Protection

• With cabinets: Modules pre-installed inside cabinets, anti-collision during long-distance delivery.
• Cabinet-free: Modules packed separately in cartons and assembled on site. LEDs and masks are easy to scratch, requiring stricter protection.

4. Cost

• With cabinets: Extra cost for cabinet materials and assembly labor, higher total price.
• Cabinet-free: Save cabinet material cost, more cost-effective.

5. Applicable Scenarios

• With cabinets: Large indoor screens, long-term operation, sites with reserved service space.
• Cabinet-free: Small-pitch conference screens, background walls, narrow spaces without rear maintenance room.

6. Flatness

• With cabinets: Frames limit deformation, uniform splicing gaps and stable flatness for large screens.
• Cabinet-free: Flatness depends on keel installation quality; uneven surface and gaps may occur with poor construction.
