Apple's Future Foldable Could Feature An E Ink Cover Display

screenrant.com:

Apple is reportedly testing an E Ink color display for its future foldable phone, as per an industry analyst. Apple's foldable phone has been rumored for years now, but there's been no concrete proof that it will launch anytime soon. While Apple tends to take its time with new technology – USB-C ports and punch-hole cameras are prime examples – its delay with foldable phones has given rivals like Samsung a chance to establish themselves in the foldables segment.

Samsung is now the market leader for foldable phones, with its Galaxy Z Flip and Galaxy Z Fold lineup close to reaching their fourth generation. Samsung's success with its current Flip 3 and Fold 3 have prompted it to pre-emptively increase supply for the new foldable phones that are expected to launch in August. Samsung has also showcased concepts of its future foldable products, which include tri-folding and slideable displays. Meanwhile, Apple appears to be mulling the use of an unusual display type for its foldable device.

In a tweet, Apple analyst Ming-Chi Kuo revealed that Apple is testing E Ink's Color Electronic Paper Display for its upcoming foldable device. This type of display will reportedly be used for the cover screen and "tablet-like applications," thanks in part to its power-saving abilities. While E Ink displays have been used for years by Amazon's Kindles, the e-readers use black and white screens. E Ink already has color displays in its portfolio, with its most recent E Ink Gallery 3 color displays being announced in April. E Ink displays are known for their slower refresh times, but the new Gallery 3 color display can refresh as fast as 1,500 milliseconds. For
