E Ink (元太科技), a maker of e-paper display panels and materials based in Hsinchu, Taiwan, has invested in Soofa, a US company that runs solar-powered e-paper kiosks on city sidewalks. The deal aims to win adoption of E Ink's 75-inch Kaleido Outdoor color boards for community messages and street advertising, E Ink said on Nov. 9.

It is E Ink's first investment in a company offering a complete digital signage system, the company [said in its release](https://www.eink.com/news/detail/E-Ink-Announces-Strategic-Investment-in-Soofa-to-Advance-Sustainable-Community-Signage?ref=asia-tech-news.ghost.io). E Ink didn't disclose the amount. Neither company said how many of the 75-inch boards Soofa will put up, where or when.

[Soofa](https://www.soofa.co/?ref=asia-tech-news.ghost.io), founded in 2014 and based in Cambridge, Massachusetts, works with more than 60 US cities, including Boston, Atlanta and Los Angeles, according to [E Ink](https://www.eink.com/?ref=asia-tech-news.ghost.io). Its kiosks need no grid connection, and a crew of two installs them. Soofa says a sign can be put up or moved in 30 minutes. The two companies began working together more than a decade ago on E Ink's black-and-white displays, E Ink said. In 2025, Soofa [said in a press release reported by Kiosk Marketplace](https://www.kioskmarketplace.com/news/soofa-to-launch-zero-carbon-street-kiosk-in-q3-2025?ref=asia-tech-news.ghost.io) that it would launch a 75-inch full-color solar street kiosk in the third quarter of that year, priced from US$29,900 installed.

Price has been a hurdle for some of E Ink's signs, by its own account: at an Aug. 13 investor conference, chairman Johnson Lee (李政昊) said its 32-inch [e-paper signs](https://asia-tech-news.ghost.io/e-ink-readies-poster-size-production-lines-up-japanese-sales-partner/) were priced high and hadn't drawn customers as expected, while mid-size 8- to 15-inch signs saw better demand, [TechNews reported](https://finance.technews.tw/2026/08/13/e-ink-holdings-2026-q2-earnings/?ref=asia-tech-news.ghost.io).

E Ink is also lining up a site for large-panel production. Its board [approved on Nov. 6](https://mops.twse.com.tw/mops/?ref=asia-tech-news.ghost.io#/web/t05st01) buying an existing plant and its land in the Guanyin industrial park in Taoyuan, Taiwan, which E Ink said would suit large e-paper production lines. The seller’s board must still approve the deal. E Ink has said mass production of its 55-inch outdoor color e-paper will start in March 2027, [as reported here](https://asia-tech-news.ghost.io/e-ink-readies-poster-size-production-lines-up-japanese-sales-partner/). Separately, E Ink [said on June 1](https://www.eink.com/news/detail/A-New-Global-Benchmark-for-Sustainable-Airport-Media-75-inch-Color-ePaper-Advertising-Display-Debuts-at-Taoyuan-International-Airport?ref=asia-tech-news.ghost.io) that 75-inch color e-paper advertising boards using its displays had been installed at Taoyuan International Airport.
