Round Display: Where Innovation Meets Elegance

In a world where form increasingly drives function, the écran rond is reshaping how we interact with devices. Departing from traditional rectangular screens, round displays introduce a modern, ergonomic, and space-saving visual format ideal for wearables, automotive clusters, industrial instruments, and retail interfaces.

From a smartwatch worn on the wrist to a digital speedometer in a vehicle, round displays seamlessly combine aesthetic appeal with technical performance, creating immersive and intuitive user experiences.

Qu'est-ce qu'un écran rond ?

A round display is a circular digital screen, typically based on LCD or OLED technology, engineered to fit non-rectangular form factors. With diameters ranging from 0.96 inches to over 10 inches, these displays enable compact integration into products like dials, gauges, and smart rings—perfect where curves matter.

How Are Round Displays Made?

• Circular masking during TFT or OLED substrate design
• Laser cutting post-assembly for clean curvature

These processes demand advanced pixel alignment, curved backlight distribution, and edge-to-edge color balance.
