E Ink Holdings announced that it plans to invest $157-$250 million in 2026, as it continues to expand its capacity, mostly to increase its production of electronic shelf labels (ESLs) and digital signage.

EIH will start producing large panels at its new H6 production line at Hsinchu later in 2026, but the company is already working to increase capacity further. The company's plan is to build a new production lin eat Taoyuan's Guanyin District, and also to expand its capacity in the US.

China-based DKE announced it is starting to produce ePaper displays on OTFT backplanes and plastic substrates. The flexible E Ink displays are branded as DKE FLEX, and are available in both monochrome and color.

The first product that DKE started to produce is a 3.9" display, used in a consumer device that wraps around a 180-degree bend (the company did not disclose the product itself).

Samsung Electronics launched a new 13" color ePaper signage device, the EM13DX. The display offers a 1600x1200 resolution, and is similar in size to an A4 paper. The EM13DX has a rechargeable battery, USB Type-C and can be deployed without permanent power cables. It can be controlled remotely via Samsung's E-Paper App and Samsung VXT.

Interestingly, Samsung says that the device case is made with a bio-resin housing derived from phytoplankton, the first display to use this new material. The display’s housing has been independently verified by global safety and sustainability certification organization UL to consist of 45% recycled plastic and 10% phytoplankton-based bio-resin.

E Ink Holdings, said that it expects its revenue and profits to both reach record highs in the next three years, as there's rising demand for large signage displays, and also strong demand for ESLs and color e-readers. 

E Ink is planning to build a new production line (which will be called H6) to expand its capacity, targeting large e-paper signage displays. The total investment in the new fab, which will be in Taoyuan, Taiwan, will be around $107 million.

Researchers from the Uppsala University and the University of Gothenburg have developed an electronic paper display made from electrically tunable pixels made from small (560 nm in size) WO₃ nanodisks. These nanodisks a reversible insulator-to-metal transition on electrochemical reduction. This transition enables dynamic modulation of the refractive index and optical absorption, allowing precise control over reflectance and contrast at the nanoscale.

The display achieves an extremely high resolution - 25,000 PPI, and so the researchers coined these "retinal ePaper displays".  The researchers demonstrated full-color video capability (>25 Hz), high reflectance (~80%), strong optical contrast (~50%), low energy consumption (~0.5–1.7 mW cm^–2) and support for anaglyph 3D display.
