Samsung Color E-Paper: a display that looks like paper and works without a power outlet
Samsung has created a small revolution in the world of digital signage with its 32-inch ultra-thin Color E-Paper display, which displays 2.5 million colours and requires no constant power. Yes, you read that right - no power is required. The image stays on the screen even when not connected to the mains.
What you need to know
Samsung Color E-Paper is an ultra-thin (just 9mm) and lightest display in its class at 2.5kg with battery. It can run on battery power for hours, as it consumes... 0.00 W. Switching the picture requires minimal power. And then the image just stays in place until you change it yourself.
According to Samsung developers, this solution was created for cafes, shops, offices, and any commercial spaces where you need to show something, but not waste electricity and nerves.

The trick is not only that the screen consumes almost no power. The secret lies in the digital ink technology. Imagine millions of microcapsules with particles of red, yellow, white and blue. When an electrical pulse is applied, the right particles rise to the surface - and you see the picture. Until you change it, no power is needed at all.
How did they squeeze 2.5 million colours into 6 inks?
Samsung has developed its own Colour Imaging Algorithm. It's based on the principle of how our eyes perceive colours: we see the average over an area, not each individual pixel. Thanks to this algorithm, a display with a standard six colours reproduces up to 2.5 million shades - 40 times more than conventional e-papers, which are stuck at 60,000.

Another engineering trick is colour distribution using the blue-noise sampling method. This allows you to place colours so that the image looks smooth and natural, without pixel stripes and noise.
What does it look like?
At ISE 2025, people came up to me and asked: "Where is the cable? It's paper!" And for good reason. The images look as natural as possible - as if they were printed on real paper. The display has already received three "Best of Show" awards.
One of the most convenient features of Samsung Color E-Paper is full remote operation via the Samsung VXT platform. Need to change the menu, update a promotional offer, or hang winter décor instead of summer? There's no need to go to the display or fumble around with flash drives.
With VXT, everything is done online - just go to the control panel, upload a new image, check how it will look on the screen, and click "Update". In a couple of seconds, the new content is already on the screen. The platform also optimises the image for the screen's characteristics so that the colours are as natural as possible.

So, in fact, it's not just electronic paper, but a smart sign that can be viewed from anywhere in the world where there is an internet connection.
What's next.
Samsung plans to release Color E-Paper in different sizes. And yes, they are not stopping. They are already working on expanding the colour palette and making the screens even cooler.
