Dasung Link 2: A portable E-ink display as a way to reduce eye strain

The idea of ​​adding an e-ink screen to a smartphone regularly returns in various forms – from experimental hybrids like the YotaPhone to separate readers that end up being used much less often than intended. Dasung Technology, which has been working with E-ink monitors for a long time, offers a more pragmatic approach: do not change the smartphone or buy a separate device, but simply connect an external “paper” display to it.

The new Link 2 is a portable 6.7-inch E-ink screen that works as a second monitor for a smartphone. Its task is to reduce the strain on the eyes when reading, working with text and consuming content where color and a high refresh rate are not critical.

E-ink display with a familiar smartphone interface

At the heart of Dasung Link 2 is a monochrome panel with a density of 300 PPI, which corresponds to the level of quality e-books. The text on such a screen looks as “printed” as possible and is comfortable for long reading.

At the same time, the device stands out for its class with increased smoothness: the refresh rate reaches 60 Hz. For E-ink technology, this is a noticeable step forward — the smartphone interface, scrolling, and basic animation are perceived as much less “ragged” than on traditional readers.

Lighting and wireless connection

So that the device can be used in different lighting conditions, an adjustable two-color backlight is provided. The temperature can be changed from cool white to a warm amber shade, which makes the screen comfortable both for daytime use and for reading in the evening.

The connection is implemented using AirPlay and Miracast wireless protocols, thanks to which Link 2 can mirror the screen of smartphones on iOS and Android without cables and additional equipment.

Compact body and focus on mobility

The body of the device is characterized by a minimalistic and thin design: the thickness is about 7 mm, and the weight is about 155 grams. In terms of dimensions, it can be compared to a small portable accessory that is easy to carry along with a smartphone.

The device is available in several variants of the body design, but the basic idea remains unchanged – the most inconspicuous, pocketable second screen for everyday tasks.

Niche gadget to reduce digital load

Dasung positions Link 2 as a tool for those who spend a lot of time reading text, editing documents or working with information on the go. Unlike conventional displays, E-ink reduces visual load due to the absence of active illumination and minimal flickering.

The price of the device is about $280, which puts it in the category of specialized accessories, rather than mass gadgets. This solution is aimed at users who are ready to sacrifice color and multimedia versatility for a more comfortable perception of text.

An alternative to classic screens

Against the background of a saturated market of smartphones and accessories, Link 2 stands out not with “maximum” characteristics, but with the opposite idea of ​​simplifying the visual experience. It’s not an attempt to replace a smartphone, but a way to offload it, leaving the primary device for tasks where color and refresh rate really matter.
