OPPO's self-developed seiko quasi-vertebral hinge technology is a brand-new folding screen mobile phone hinge technology. Compared with the U-shaped hinge of other folding screen mobile phones, the bending radius of the self-developed "Seiko Quasi-vertebral Hinge" carried by OPPOFindN is increased to 3.0mm, which is roughly 1.5mm compared with other folding screen mobile phones. The bending radius of OPPOFindN is larger, which can further reduce the stress of the hinge on the screen, which also makes the OPPO folding screen less prone to crease.
In addition, OPPOFindN is equipped with three torsion modules with the same specifications, which makes the opening and closing feel and strength more controllable. The gap between these torsion modules also creates a different folding screen interactive experience for OPPOFindN-a brand-new hovering interactive way. When taking a selfie, watching a video or chatting on video, you can use OPPOFindN's water drop hinge to hover from multiple angles to realize different experiences.
