While portable displays have been available as far back as at least 2012, they’ve become more popular in recent years as they can both offer a secondary display to your laptop, or add a larger screen to your smartphone. In the last two years, we’ve already covered BlitzWolf BW-PCM1, T-bao T15A, TAIHE Gemini (which ended up being a failure), Airview, and Desklab among others. But apparently, there’s room for more with the launch of AirTab, a 15.6″ portable touchscreen or non-touch monitor, on Kickstarter that’s already surpassed its $10,000 funding target.

4.2″ and 7.5″ NFC-powered e-Paper Displays Work without Battery

e-Paper displays have great readability under sunlight, and only consume power when updated. But their refresh rate is limited, and most displays are fairly expensive. One way to reduce the cost is to completely remove the battery from the display, and update it through NFC providing both data and power. I’ve just found out about that possibility through 4.2″ and 7.5″ displays offered by Waveshare. All you need is a compatible NFC smartphone, or the company’s ST25R3911B NFC Board to power the display and transfer your image of choice. This works best for signs you may need to infrequently update such as menus, daily schedules, conference badges, labels, etc… Waveshare NFC-powered e-Paper display key features and specifications: Screens 7.5″ display 800×480 resolution 2-level greyscale 170° viewing angle Refresh Time – 5s + data transfer time 4.2″ display 400×300 resolution 2-level greyscale 170° viewing angle Refresh Time – 4s + data transfer time Wireless Connectivity – NFC Power Supply – Wireless …
