crepesoled

Crepesoled is a term used in documentation and design discussions to refer to a family of flexible, low-profile light-emitting diode modules distinguished by a crepe-like surface diffuser and a pliant substrate. The name combines crepe, referencing a wrinkled texture, with LED, highlighting its flexible form factor. In practice, crepesoled denotes either a class of products or a design approach rather than a single standardized product.

The term began appearing in design blogs and hardware forums in the early 2010s as designers experimented with wrapping LEDs around non-planar surfaces. Crepesoled modules typically use a thin, bendable polymer or polyimide substrate with mounted micro-LEDs or LED dies, a flexible electrical interconnect, and a silicone or epoxy encapsulation that induces a diffuse, even light output.

Key characteristics include: high flexibility, low thickness, and diffuse illumination. The crepe-like diffuser improves uniformity by scattering light across the surface. Color rendering is generally kept within standard LED ranges, with support for common color temperatures. Efficiency is competitive with other flexible LED approaches, though manufacturing tolerances and reliability at tight radii can vary between suppliers.

Applications cited for crepesoled include architectural accents, curved signage, wearables, automotive interiors, and consumer electronics enclosures. Because the term is not tied to a single standard, implementations vary by substrate, interconnect, and encapsulation. At present, crepesoled remains a niche or design-specific term rather than a widely standardized technology. See also flexible display technologies, LED packaging, and micro-LED.
