Although E Ink technology has remained a largely niche display tech over the past decade, it's none the less excelled in that role. The electrophoretic technology closely approximates paper, providing significant power advantages versus traditional emissive displays, not to mention making it significantly easier on readers' eyes in some cases. And while the limitations of the technology make it unsuitable for use as a primary desktop display, Phillips thinks there's still a market for it as a secondary display. To that end, Philips this week has introduced their novel, business-oriented Dual Screen Display, which combines both an LCD panel and and E Ink panel into a single display, with the aim of capturing the benefits of both technologies.

The Philips Dual Screen Display (24B1D5600/96) is a single display that integrates both a 23.8-inch 2560x1440 IPS panel as well as a 13.3-inch, greyscale 1200x1600 resolution E Ink display. With each display operating independently, the idea is similar to previous concepts of multi-panel monitors; however Phillips is taking things in a different direction by using an E Ink display as a second panel – combining two otherwise very different display technologies into a single product. By offering an E Ink panel in this product, Phillips is looking to court the market for users who would prefer the reduced eye strain of an E Ink display, but are working at a desktop computer, where an E Ink display would not be viable as a primary monitor.

As you might expect from the basic layout of the monitor, the primary panel is a rather typical office display that's designed for video and productivity applications – essentially anything where you need a modern, full color LCD. The secondary E Ink display, on the other hand, is a greyscale screen whose strength is the lack of flicker that comes from not being backlit by a PWM light. Both screens act independently, but since they are encased into the same chassis, they are meant to work together. For example, the secondary monitor can display supplementary information in text form, whereas the primary monitor can display photos.

Ultimately, Philips is pitching the display on the idea that the secondary screen can reduce the eye strain of the viewer while viewing documents. It's a simple enough concept, but one that requires buyers to overlook the trade-offs of E Ink, and the potential drawbacks of having two dissimilar displays directly next to each other.

Under the hood, the LCD panel on the Deal Screen Display is an unremarkable office-grade display. Phillips is using 23.8-inch anti-glare 6-bit + Hi FRC IPS panel with a 2560x1440 resolution, which can hit a maximum brightness of 250 nits while delivering 178-degree viewing angles. Meanwhile, the E Ink panel is a 13.3-inch 4-bit greyscale electrophoretic panel, with a resolution of 1200x1600. Notably here, there is no backlighting; the E Ink panel is meant to be environmentally lit (e.g. office lighting) to truly minimize eye strain.

When it comes to connectivity, the primary screen is equipped with a DisplayPort 1.2 and a USB Type-C input (with DP Alt mode and USB Power Delivery support), a USB hub, and a GbE adapter. Meanwhile, the secondary screen connects to host using a USB Type-C connector that also supports DP Alt Mode, and Power Delivery.

The Philips Dual Screen Display has a rather sleek stand which can adjust height, tilt, and swivel. It makes the whole unit look like one monitor rather than like two separate screens. Though to be sure, the E Ink portion of the display can be angled independently from the LCD panel, allowing the fairly wide monitor to contour to a user's field of view a bit better.

When it comes to pricing, Philips's Dual Screen Display is available in China for $850 (according to Liliputing), which looks quite expensive for a 24-inch IPS LCD and a 13.3-inch secondary screen. Though as this is a rather unique product, it is not surprising that it is sold at a premium.

    solution in search of a problem

    Quite a few places where people need to refer some reading material that will work perfectly. Hospitals, offices, etc... loads of places can make use of such solutions though as pointed above quite badly executed with 6bit primary display.

    Struggling to believe that 6 bit at 75Hz max is a thing, especially in 2023, especially at that price

    I even have a philips IPS LCD from 2011 with 60Hz 8 bit panel (taiwanese)

    Some conflict in specs there: main body says 23.8" main display, spec round-up box says 27" IPS 6-bit + Hi FRC

    6-bit + Hi FRC is pretty much what everyone who thinks they have 8-bit screens really have.
    $850 isn't that expensive, since 13.3 inch e-ink isn't very common.
    This is great if your job is to write or edit ebooks, you can basically work and compile it on the left and have it output on the right, exactly as your reader will see on their kindle/kobo.
