E Ink Color Technology, Product and Applications

Hui Karen Du, AVP, E Ink Corporation

Presentation Abstract

Have you seen the BMW iX Flow concept car at CES 2022? It is wrapped with E Ink digital paper and displays a transformation in the way surfaces are experienced.

E Ink Holdings Inc. is the worldwide leader of Electrophoretic display technology and products. Since 20 years ago, E Ink has transformed and defined the eReader market, enabling a new multi-billion dollar business. Over the last 10 years, the company has developed revolutionary electrophoretic ink with multi-color pigments that enable displays to show a variety of vivid and vibrant color images besides black and white.

During this presentation, the unique features and advantages of E Ink display technology will be introduced and compared with emissive display (LCD, or LED) technology. Further, E Ink’s color ink design, color generation mechanism, and display film structure will be discussed and the major products and applications in consumer electronics and IOT ranging from retail, home, hospital, transportation, smart packaging and fashion, etc that are enabled by color E Ink will be presented. Finally, the vision of smart surfaces with E Ink technology will be presented, a technology that will transform static spaces into something dynamic, spectacular, personalized, and informative.
