Sharp Shows 6.18” Foldable Prototype
April 22, 2019
According to EngadgetJP, Sharp’s prototype features a 6.18-inch OLED display with an elongated WQHD+ 1,440 x 3,040-pixel resolution. It’s reminiscent of Sony’s new Xperia 10 and Xperia 10 Plus devices with their long 21:9 displays, but Sharp’s would be much easier to pocket given it folds down to half its size. The device is an inward bending approach that stresses the folding screen given the smaller radius it has to compress to, which results in a more apparent crease in the middle of the display. But Sharp’s representatives said it can survive over 300,000 bends before the wear starts to physically damage the OLED, which computes to eight years of use at 100 times per day. Sharp wouldn’t comment on if or when Sharp plans to introduce the folding screen technology on its line of Aquos smartphones, but it did confirm that the screen could be implemented with an outward folding design as well.

Nubia patented 16 different designs (via two separate patents on WIPO) for a flexible display, and all 16 of them sport notches. Eight designs include two notches, one on the top, and one on the bottom of the display, while the other eight designs sport notches only on the top. These are patents for a smartphone display, and the company would not really patent this if they did not plan to utilize at least some of them on smartphones. Display notches are not exactly loved by users, and this may not be the best idea for Nubia, at least when designs with notches on the top and bottom are concerned, but it sure is… different. These two patents were submitted in March 2018, but they were published on April 12. These displays seem to sport really tall display aspect ratio, 21:9 if not higher. Nubia recently released a smartwatch phone, featuring a flexible display that bends around the watch band. These flexible display patents may be aimed at Nubia’s foldable smartphone.
