An interview with reflective display developer Solchroma

US-based Solchroma develops a novel reflective inks and actuators based display technology, targeting the outdoor signage market (at least as a first step).

The company introduced its interesting technology at SID Displayweek 2021. The company's CEO, Dr. Roger Diebold was kind enough to explain the company's technology and business to E-Ink-Info.

Hello Roger, thank you for your time. Can you explain Solchroma's ePaper technology?

Solchroma creates reflective digital displays to change how we interact with the built environment and world around us. Solchroma’s technology is based on hydraulically forcing of colored liquid ink in and out of view. A backplane of actuators acts as an array of electrically-controlled pumps that push on nearby reservoirs of ink. Ink reservoirs are shielded from view by a white reflector, while simultaneously allowing passage of ink from the reservoirs behind the reflector to three sealed, viewable chambers stacked one atop the next on the viewable side.

Looking for ePaper panels and systems? We can now assist

If you're looking for ePaper display modules, we can now help you find suitable suppliers for a wide range of displays. These can be bought as stand alone displays, or as a complete system solution.

We can support over 15 displays, ranging from small 1-inch displays for wearables and small devices to 13.3" panels. Most of these displays are monochrome (Black/White) but some also support three colors (Red or Yellow). A few of these displays are flexible.

The best of 2020 - top ePaper stories

2020 is soon over - and many in the world are really happy about that and hope that 2021 will bring the COVID-19 pandemic to an end. The entire world was effected, including the ePaper industry, although we also saw high demand for devices that support work-from-home and study-from-home, such as e-notebooks and e-readers.

ePaper displays in 2020 - a market snapshot

Most people when they think about ePaper displays immediate think about E Ink. E Ink Holdings (EIH) has been very successful in bringing its ePaper displays to the market - and today these are prevalent in e-readers, electronic shelf labels, e-notebooks and many other applications. While EIH indeed has a clear leadership in the ePaper market, it is not alone.

But first of all, it is important to note that there are many display technologies that could be called ePaper displays. Most people would only consider truly bi-stable displays able to show dot-matrix images as ePaper displays, but some other technologies that are not truly bi-stable also exist and some consider these as ePaper displays as well - for example Memory LCDs. In addition some simpler displays technologies that are similar to ePaper in properties also exist. We will discuss both these technologies in this article.

How Dasung's E Ink monitor assists a Syndome Triple-A patient

Jeremie Rousseau, from France, suffers from a genetic disease called Syndome Triple-A, a rare autosomal recessive congenital disorder. There are several symptoms that result from this disorder - and one of these is alacrima - the inability to produce enough tears. Jeremie finds it very difficult to work with computer monitors - even after following his Doctor's advice to decrease the contrast and brightness of his LCD display.

Jeremie was looking for solutions that will enable him to work for longer times in front of a monitor, and he found a good solution with Dasung's Paperlike E Ink monitors. Jeremie finds that he can work for many hours in front of the E Ink monitors - used to read, write e-mails and read long PDF files.

An introduction to e-paper displays video

e-Paper displays offer exciting features, such as great image quality, low power consumption (bi-stability), sunlight visibility and more. Here's our new short video that introduces e-paper display technology and the current market status:

Hands-on review of Dasung's 13.3" Paperlike HD-FT monitor

In July 2019, Dasung started shipping its third-generation E Ink secondary monitor, the Paperlike HD-FT. This e-paper monitor is based on a 13.3" 2200x1650 touch display with a front light. Dasung was kind enough to send us a unit for this review.

The Paperlike HD-FT is a surprisingly slick and lightweight monitor. It's like a large tablet or a large e-reader, but one that connects to your computer via a single cable that requires two connectors - USB for power and HDMI for data. The monitor than acts like a regular 2nd monitor.
