He promised it a few days ago, and Royole FlexPai 2 has arrived: this is the sequel to the world's first folding smartphone. The presentation was technical and full of details, especially related to the display and hinge technology, but the real smartphone has not been seen much. Nor have we talked about several key aspects, such as cameras, autonomy, price and availability. The event was dedicated to the display, rather than to the smartphone.
In any case, the meat on the fire is already a lot. The flexible OLED display, which Royole calls Cicada Screen (the cicada is a superfamily of insects with transparent wings), it is now in its third generation. Royole has made important progress in making it even thinner and more flexible, while maintaining a certain durability over time. The result is that the famous fold seen in the leaflets released so far has been completely eliminated, at least according to the renders shown by Chinese society. The display still manages to survive over 200,000 folds, according to Royole's laboratory tests.
The display is also built in such a way prevent the creation of any “bellies” of the lower layers when stretched. The bend radius can therefore also be narrower.
At the same time also significantly improves the quality of the panel: the brightness rises 50% compared to the previous generation, the JCND (Just Noticeable Color Difference) drops to 0.6 at an angle of 30 °.
Much attention has also been paid to the hinge, which Royole calls 3S (Super Seamless & Stepless): in a nutshell, compared to the previous generation, it is more refined, more resistant to long-term use and better withstand accidental bumps and falls. Another important novelty does not have a fixed position: it can rotate freely so that the user is free to stop the display at the angle he prefers – paving the way for notebook-style use, to understand each other. However, the maximum bending angle remains 180 °.
For the rest of the specifications, Royole simply talks about Qualcomm Snapdragon 865 SoC, with 5G connectivity (9 bands for guaranteed connectivity also in Europe and the USA, even if we don't have more precise details), LPDDR5 RAM, UFS 3.0 internal storage chip, quadruple camera and stereo speakers. The size of the display should remain more or less unchanged compared to the original FlexPai – around 7.8 “- but we have no information on the resolution.
Royole also announced one partnership with ZTE, the Chinese telecommunications giant, so it is likely that in the future we will see its flexible technology on other devices. FlexPai 2 is expected to be launched in the second quarter of 2020, however.
