Samsung Color E-Paper EM32DX: Inside story of the groundbreaking e-paper technology – NotebookCheck.net News
The Samsung Color E-Paper is a new digital signage solution capable of retaining images without requiring continuous power. The 32-inch display delivers QHD resolution and supports up to 2.5 million colors, all while consuming an exceptionally low amount of energy.
In April 2025, Samsung unveiled the Color E-Paper EM32DX, a 32-inch e-ink display designed especially for commercial spaces, such as retail shops and food & beverage establishments. Notably, the panel can display static content without requiring a continuous power supply, setting new standards in energy efficiency and sustainability.
According to Samsung, the Color E-Paper uses a microcapsule ink technology, where each capsule contains four color pigments (red, yellow, blue and white) that selectively rise to the surface when an electric current is applied – a working principle similar to conventional printing. Once an image is formed, it can be retained without consuming additional power. Measuring just 8.6 mm (0.3 in) thick and weighing a mere 2.5 kg (5.5 lb) with the battery included, the system offers flexible installation options thanks to its thin and lightweight design.
One key feature of the Color E-Paper is Samsung’s proprietary Color Imaging Algorithm, which allows the display to reproduce up to 2.5 million hues with just six base colors by leveraging probability distribution and optimized color arrangements. Samsung claims a 40-fold improvement in color richness compared to conventional e-paper solutions, and images also appear exceptionally smooth and easy on the eyes.
The system can be managed through the Samsung VXT platform, which supports features like color preview, layout planning and content update. Furthermore, the display incorporates recycled plastic in its body and is shipped in eco-friendly packaging.
The Samsung Color E-Paper technology was showcased at Integrated Systems Europe (ISE) 2025, where it received several awards. Samsung also revealed plans to launch more display sizes and continue advancing its research in color optimization.
