Dasung Link 2: A 6.7-Inch E-Ink Monitor for Smartphone Mirroring

Priced between $329 and $379 depending on the battery configuration, the device positions itself as a dedicated secondary display for extended reading and low-eye-strain tasks — a category that has seen renewed competition with AOC's recently launched 13T5S color E-Ink monitor.

Core specifications and display pipeline

The Link 2 uses a monochrome E-Ink panel with a 300 PPI pixel density, matching the rendering sharpness of current-generation flagship e-readers. Wireless screen mirroring is employed to broadcast content from both iOS and Android devices, with the Link 2 inheriting the host phone's CPU, RAM, and app performance. Compatibility is listed at Android 12 and later, plus current iOS and HarmonyOS versions.

Dasung's proprietary high-speed refresh technology operates at 60Hz, a specification the company claims enables fluid scrolling, typing, and video playback with minimal ghosting — a persistent bottleneck in E-Ink displays optimized for static text rendering. The device includes a dual-tone adjustable frontlight for ambient and low-light conditions, and reverse touch controls allow direct interaction (tapping, swiping) on the E-Ink surface itself, eliminating the need to switch back to the phone screen for basic navigation.

Build and power considerations

The chassis is an ultra-thin, lightweight metal body with multi-function physical keys dedicated to image enhancement and contrast adjustment. Two trims are offered: Space Grey and Glacier Blue. The device ships in a battery-free variant at $329 and a battery-equipped variant at $349. Compatibility with magnetic power banks is noted for extended portable use, though battery capacity figures and runtime estimates have not been disclosed by Dasung at this time.

Market positioning and competitive context

The Link 2 enters a niche but growing segment of portable E-Ink companion displays. AOC's 13T5S, launched at roughly the same time, targets a different use case: a larger 13.3-inch Kaleido 3 color E-Ink panel at 30Hz with AI-assisted ghosting reduction, positioned for document editing and reading at a desk rather than smartphone mirroring on the move. The refresh rate differential (Dasung's 60Hz versus AOC's 30Hz) and the monochrome-versus-color distinction represent the primary technical trade-offs between the two approaches.

For readers evaluating E-Ink secondary displays for newspaper and PDF access, the Link 2's 300 PPI monochrome panel and 60Hz refresh claim warrant hands-on verification — ghosting performance at sustained 60Hz on E-Ink hardware has historically varied significantly between manufacturer specifications and real-world rendering of complex layouts. The absence of published input lag or rendering latency data from Dasung means the actual responsiveness of the reverse touch controls under load remains to be independently tested.
