The electronic device in question features a flexible display incorporated into a foldable design. This device comprises a hinge module connecting two housings, allowing them to fold against each other. The flexible display is supported by these housings and includes several layers: a window layer on top, a display panel beneath, and additional components for added protection and flexibility. The design specifically addresses issues related to the durability of the display when subjected to frequent folding and external impacts.
The flexible display includes a window layer and a display panel, which has both a plane part and a bending part. The bending part extends from the plane part and folds from the edge area adjacent to the second housing's side wall towards the rear surface. To enhance durability, a buffer part is placed between the display panel and the second housing, covering at least part of the edge area along with the bending part. Embedded within this buffer part is at least one protection member that provides additional support against external forces.
The foldable electronic device is designed to handle interlayer slips that occur during folding operations. The application of either hard or soft molding liquids influences how well the device can manage these slips. While hard molding liquids might lead to buckling due to restricted movement, soft molding liquids offer flexibility but may compromise durability. The inclusion of protection members aims to balance these factors, ensuring both flexibility and impact resistance.
The electronic device can operate in both in-folding and out-folding manners, with the first housing rotating up to 360 degrees relative to the second housing. In its unfolded state, the device presents a large-screen display supported by both housings. The design omits traditional protective covers at the edges, opting instead for a visible edge that is still protected against damage through innovative structural elements like the buffer part and protection members.
This foldable design not only enhances portability but also maintains high durability standards despite frequent folding operations. By incorporating a soft buffer part and strategically positioned protection members, the device mitigates potential damage from external impacts while allowing for necessary flexibility during use. These innovations contribute to an overall improvement in surface quality and functionality, providing users with a robust yet adaptable electronic device.
