4. The driving component adopts a driving motor 333 as a driving source, and is beneficial to controlling the stroke of compensation displacement and improving the compensation precision through the meshing transmission mode of the gear 332 and the rack 331.
5. The flexible display panel 100 adopts a structure that two opposite ends are respectively folded and bound, which is beneficial to adapting to application scenes that related electrical devices need to be distributed dispersedly.
6. The first sub-slider 321 and the second sub-slider 322 are respectively driven by the first driving sub-assembly and the second driving sub-assembly, so that independent driving of binding sub-regions on any side can be realized, differential displacement compensation can be provided, and compensation precision is improved.
7. The controller 430 may control the displacement compensation assembly 300 to drive the binding region 130 and the supporting structure 200 to make a relative movement corresponding to the current relevant bending real-time information according to the bending state information of the foldable display module 11 monitored by the first sensor 410 and the relevant bending real-time information such as the displacement information between the flexible display panel 100 and the supporting structure 200 monitored by the second sensor 420, which is not only beneficial to realizing the automatic displacement compensation, but also beneficial to improving the compensation precision for the displacement difference between the flexible display panel 100 and the supporting structure 200.
8. The support layer 210 in the support structure 200 may provide sufficient support, and the first and second backing layers 220 and 230 may provide a certain protection for the display region 110 and the binding region 130 of the flexible display panel 100 after being folded back, respectively.
9. The buffer layer 240 may provide a certain elastic space between the support layer 210 and the second back film layer 230, which is beneficial to improve the protection of the bonding region 130 of the flexible display panel 100.
10. The first neutral layer 250 can adjust the distribution of the neutral film layer in the foldable display module 11, so as to ensure or improve the device performance.
11. The second neutral layer 510 may provide at least one protection including support, insulation, scratch resistance, etc. to the bending region 120 of the flexible display panel 100, thereby reducing the failure rate of the flexible display panel 100, extending the service life of the product, and reducing the use cost of the product.
