With the rise of foldable screen phones, how to ensure the precise alignment of the screen when folding and unfolding has become a key technical challenge. Magnets for foldable phones play a vital role in this process.1. How magnets workIn foldable screen phones, magnets are cleverly arranged on the inside of the screen and other key parts of the body. These magnets are not only used to fix the screen to keep it stable in the folded state, but also through the precise magnetic circuit design, the precise alignment of the screen during the unfolding and folding process is achieved.2. How to achieve precise alignmentMagnetic induction and fixation: Foldable screen phones are equipped with magnet units at the four corners or edges of the screen. These magnets attract each other when folded, forming a stable fixing force to prevent the screen from moving or misaligning in the folded state. Some magnets are also used for magnetic induction. When the screen is unfolded or folded to a certain angle, the magnets will trigger the corresponding sensors to realize the automatic opening or closing of the screen, as well as the switching between the screen display and the sleep state.Controllable magnetic force design: Through precise magnetic circuit design and magnet arrangement, foldable screen phones achieve controllable magnetic force. This design allows the screen to maintain steady and smooth movement during folding and unfolding, while ensuring that the screen can stay stable at any angle. The surface of the magnet is usually treated with corrosion-resistant nickel plating to ensure that the magnet can maintain stable performance in different environments, thereby further ensuring the precise alignment of the screen.Synergy between hinge and magnet: The hinge structure of foldable screen phones is also one of the key factors in achieving precise screen alignment. The hinge not only provides physical support for the screen to fold and unfold, but also works with the magnet to ensure that the screen maintains a stable posture during folding and unfolding. Magnets or magnetic materials are usually set inside the hinge to interact with the magnets on the screen, further enhancing the stability and precise alignment of the screen.Magnets for foldable phones ensure the precise alignment of the screen when folding and unfolding through magnetic induction, controllable magnetic force design and synergy with the hinge. This design not only improves the stability and durability of foldable screen phones, but also brings users a smoother and more convenient user experience.
