This massive color E-in-the-way display is the whole drive wireless

While there were many e-ink color screens that were shown in the Digital Signage section in Ise 2025, Wi-Poster Techradar Pro caught the attention of the only one who uses wireless power.

Available in a number of sizes from 13in up to 40 inches, it is the first work product we have seen that uses wireless power at a distance.

A man who saw that work at the same time as us described it as ‘magic’ and we should agree.

ORI mother, CEO and founder of Wi-Charge, Techradar Pro Wireless Power said, means not only companies can put Wi posts wherever they want, but wireless power means it is effectively permanently driven.

This means that images can be updated over Wi-Fi as many times as necessary without having to worry about ever having to connect it to a portable power plant or network line to charge batteries.

“Over time, the cost of replacing batteries can really mount, so over time our wireless power solution can save companies a lot of money and reduce waste to a great extent. And even with a rechargeable battery, you still have to spend time and costs getting power to them when they run down ”.

Mother said Wi-Charge’s wireless power solution, called “aircord”, uses infrared to send up to 350 milliwatt power from a transmitter connected main network to units with a built-in receiver up to 10 meters away. A transmitter can send power to multiple devices at once, but any device requires a line of view to a transmitter. The current stream ceases as soon as something gets in the way but resumes immediately afterwards.

Of course, we speculated on the security of sending power over the air like this, but Mother assured us that it was for sure and has been ratified by all global standards agencies, such as IEC and CE in Europe and FC and FCC in the United States.

Like a Spectra 6 screen, the Wi-Poster images saw impressively colorful and lively. Almost cannot be distinguished from paper, they remain visible, even under sunlight. Mother demonstrated the Wi-Poster update and took about 30 seconds to the picture to change.

However, e-Ink is not suitable for video, and to that, Mom said that Wi-Charge already has a ‘aircord’-driven LCD screen on the market called Wi-Spot. Mother, who was available in either 7 and 9-instant, said Mother that this was primarily aimed at product-affecting advertising for the retail market.

He said the Wi spot also contains motion sensors, enabling companies to collect foot-drop statistics to provide data to optimize store layouts.

Wi-Charge also had a wireless driven toothbrush holder and an X-Box controller on show, though they turned out to be prototypes rather than actual products for sale.
