E Ink, a producer of digital paper technology, has partnered with TPV Technology, a manufacturer of PC monitors and LCD TVs, to develop a 25.3-inch E Ink Spectra 3100 display for the transportation and retail markets, according to a company press release.

In April 2021, the two companies launched a 7.3-inch eTable sign with E Ink Spectra 3100 technology and have now expanded their partnership with the four-color ePaper signage.

"We are pleased to work more closely with TPV Technology and to bring E Ink Spectra 3100 color ePaper into large sizes. Spectra has traditionally been used in shelf labels; through this effort we can now bring our four-color ePaper into the smart transportation field," Johnson Lee, CEO of E Ink Holdings, said in the release. "As governments and companies around the world look to reduce their carbon emissions, E Ink has worked with ecosystem partners to create ePaper signage with ultra-low power consumption, to help our customers reach their goals of Net Zero Carbon Emissions."

The ePaper display features black, white, red, and yellow pigments. When used as transportation signage for railways and buses, it can display alerts and reminders, schedules and changes or other notifications for travel. And when applied in the retail field, it can be used as POP signage to promote product information.

"TPV Technology and E Ink have already successively developed black and white 31.2-inch and 42-inch ePaper signage. The new 25.3-inch ePaper display is designed to have four colors. Images can be presented in bright and eye-catching colors, including black, white, red, and yellow, which are more suitable for use in digital signage to attract consumers' attention," Lin Chun-Fu, VP of TPV Technology Group, said in the release. "TPV has customers based in retail, advertising, railway, commercial displays, and other applications, and we hope to substantially expand the market through our partnership."

The product has been piloted by system integrators such as CREA Co., Ltd from Japan, and Ledatel Group from Poland. Future applications include railway transportation, advertising billboards and retail stores, according to the release.
