Hisense Introduces Dual-Screen E-Ink Smartphone After Four-Year Hiatus
According to Zamin.uz, Hisense has reintroduced a dual-screen E-Ink smartphone, ending a four-year absence from the category it effectively pioneered for mainstream consumers.
A separate listing from Mshale references the Hisense A10 E Ink Phone and describes the device as the "World's First Detachable Color Screen Smartphone," indicating that the new product pairs a monochrome E-Ink panel with a detachable color secondary display rather than relying on a single integrated panel.
Device Architecture and Display Configuration
The defining characteristic is the detachable second screen. Rather than fixing a color LCD alongside the E-Ink panel on a single chassis, Hisense appears to have separated the two displays into a modular configuration. For e-paper reading, this matters on three technical axes: panel density on the E-Ink side, rendering latency when content is pushed between displays, and how the operating system arbitrates between the monochrome and color surfaces.
Without a confirmed specification sheet, the practical questions for users remain open: whether the E-Ink panel matches the 300 ppi threshold widely treated as the minimum for comfortable newspaper and PDF column rendering, whether the detach mechanism preserves state when reconnected, and whether frontlight uniformity — a known weak point on earlier Hisense phones — has been addressed. The detachable color component also introduces a continuity question: detached, the device reverts to monochrome-only, which is acceptable for reading but limits the use cases the manufacturer is likely to market.
Implications for E-Paper Readers
For readers who use e-paper primarily for long-form news, journal articles, and PDF archives, the dual-screen concept has direct utility if executed correctly. The monochrome panel can serve as the dedicated reading surface — extended sessions without backlight, full sunlight legibility, minimal ghosting on page turns — while the color panel handles subscription authentication, app updates, and any task that requires color fidelity. This is a cleaner division of labor than the earlier A5, A7, and A9 generation phones, which forced color tasks onto the E-Ink panel with predictably poor refresh behavior.
What to Verify Before Adopting
Three data points will determine whether this device is worth tracking: the E-Ink panel resolution and refresh mode set, the latency cost of switching workloads between the two screens, and battery life under a reading-heavy profile with the color display detached. Until Hisense publishes a specification sheet or an independent teardown confirms the internals, the announcement should be treated as a hardware return of interest rather than a confirmed reading platform. Readers currently on a Hisense A9 or comparable older device should wait for measured ppi, ghosting benchmarks, and a documented frontlight test before migrating.
