The Sonostar smartwatch was jointly developed by E Ink’s subsidiary Transmart Co. Ltd and Sonostar. The 1.73” Mobius display supports a resolution of 320X240 pixels with 16 greyscale levels. The display size and characteristics make the technology ideal for the smartwatch market.

Using a flexible substrate, the 1.73” Mobius is lightweight and rugged and is conformable so the end product has a better fit for the consumer. Its low power usage and sunlight readability make this technology ideal for mobile devices. Unlike conventional displays, the 1.73” Mobius display can be cut into different shapes.

"The joint development between Sonostar and Transmart is the perfect example of the how E Ink can help its customers get their product to market,” said Giovanni Mancini, director of product management for E Ink Holdings.

“E Ink displays enable unique products that capture the customer’s imagination. Our business development team has the expertise to help our customers design the displays into their products in ways never before thought possible.”
