Pioneering invention of smart E-ink screen phone case

Congratulations to Han Hongda for winning the ePIC 2023 Electronic Paper Innovation Application "Pioneer" Award

Shenzhen Hanhongda Electronic Technology Co., Ltd. will bring new flowers to the innovative old tree of electronic paper. In 2022, it launched the Apple phone back case series by combining NFC radio frequency power harvesting technology with three color electronic paper. Due to the adoption of a battery free design, the phone back case has no built-in battery, which solves the problems encountered by products in this field before.
