Viewlink Engineering Team

Hardware, firmware and panel engineering, Shenzhen

We are the hardware, firmware and panel engineering group behind Viewlink Technology, an e-paper design house and manufacturer founded in Shenzhen in 2018. Our work covers board design, display integration, enclosure and front-light mechanics, and the firmware that decides how a page actually turns.

Most of what we write here starts as an internal answer: why a panel ghosts after a partial refresh, why a colour filter array costs contrast, why a battery that looks generous on paper runs flat in a week. We publish it because buyers and partners ask the same questions before a project starts.

Our production base in Bao'an runs four flexible assembly lines across 8,000 m² under an ISO 9001:2015 quality system, which means the trade-offs we describe are the ones we have to live with at volume, not just on a bench.

What we work on

E Ink panel selection and waveform tuning
Low-power Android and RTOS firmware
Front-light, touch and enclosure integration
Pilot-to-volume manufacturing
