Flexible LED Display

What Is a Flexible LED Display?

A flexible LED display is a display system consisting of modules manufactured on a bendable substrate material instead of a rigid circuit board. Since the modules can be bent to a certain radius, they can be used on curved surfaces where flat panels cannot be applied.

The flexibility of the substrate does not alter the arrangement of the LED chips or the operating principle of the driver electronics. Image generation occurs in the same way as with standard modules; the only differences are the physical structure of the module and the installation method.

Application Types

Flexible modules are typically used to conform to architectural surfaces. This includes concave and convex shapes, cylindrical column cladding, undulating ceiling surfaces, and corner transitions.

Advantages of Flexible LED Screens

Applications

• Column cladding in hotel and plaza lobbies
• Store windows and curved display surfaces
• Cylindrical totems and wayfinding points inside shopping malls
• Wavy wall installations in corporate reception areas
• Showrooms and brand experience areas

Flexible modules are primarily manufactured using SMD packaging. For curved applications requiring close viewing distances, COB options may also be considered.

Mounting Methods

Flexible modules are typically mounted to the mounting surface using magnetic connections or screw fasteners. The method is selected based on the surface geometry and service access.

Items to Be Determined During the Design Phase

In flexible LED applications, most errors occur during the design phase, not during installation. The following points must be clarified during the design phase:

• Surface radius measurement. There may be a difference between the architectural drawing and the actual surface on-site; measurements must be taken on-site.
• Module limit value. The minimum bending radius of the selected module must be compared with the narrowest point of the surface.
• Heat dissipation. Ventilation gaps must be left in columns encased within enclosed spaces.
• Service access. In cylindrical installations, access to the module in the event of a malfunction must be planned in advance.
• Cable routing. The bending radius of data and power cables is also limited on curved surfaces.

Maintenance and Service

The maintenance requirements for flexible modules are similar to those for flat panels; the difference lies in access. A platform or scaffolding may be required for service in locations such as columns and ceilings; this need should be anticipated in the installation plan.

Surface cleaning should be performed with a dry or slightly damp microfiber cloth. Cleaning products containing solvents should not be used, as they may damage the base material and coating.
