FIG.1CandFIG.1Dare schematic diagrams of the electronic device1being bent in accordance with some embodiments of the present disclosure. As above mentioned, the substrate108and the protection layer109of the flexible body10of the electronic device1is pliable, and thus the flexible body10of the electronic device1could be bent as shown inFIG.1Cand/orFIG.1D. The first portion101and the second portion102of the flexible body could be moved relative to each other when the flexible body10of the electronic device1is bent. However, there may be many electronic components integrated in the electronic device1, and thus the electronic components in the electronic device1may be damaged or disabled in case the electronic device1is excessively bent. Especially, the electronic component11which disposed in the first portion101and the second portion102of the flexible body10may be damaged due to the over-bending of the electronic device1.

Referring toFIG.1C, the first portion101and the second portion102are moved toward each other when the flexible body10of the electronic device1is bent. As shown inFIG.1C, a lower surface of the first portion101and a lower surface of the second portion102are moved toward each other, and the end portion121of the magnetic element12and the end portion131of the magnetic element13are moved toward each other as well. As above mentioned, the magnetic polarity of the end portion121of the magnetic element12may be the same as the magnetic polarity of the end portion131of the magnetic element13. Therefore, the magnetic elements12and13may generate a repulsive force with each other when the end portion121of the magnetic element12and the end portion131of the magnetic element13are moved toward each other. Such repulsive force generated by the magnetic elements12and13may resist the relative movement between the first portion101and the second portion102and thus may restrict the electronic device1from being excessively bent. That is, the electronic component11may be prevented from being damaged due to the repulsive force generated by the magnetic elements12and13.

Referring toFIG.1D, the first portion101and the second portion102are moved toward each other when the flexible body10of the electronic device1is bent. As shown inFIG.1D, an upper surface of the first portion101and an upper surface of the second portion102are moved toward each other, and the end portion122of the magnetic element12and the end portion132of the magnetic element13are moved toward each other as well. As above mentioned, the magnetic polarity of the end portion122of the magnetic element12may be the same as the magnetic polarity of the end portion132of the magnetic element13. Therefore, the magnetic elements12and13may generate a repulsive force with each other when the end portion122of the magnetic element12and the end portion132of the magnetic element13are moved toward each other. Such repulsive force generated by the magnetic elements12and13may resist the relative movement between the first portion101and the second portion102and thus may restrict the electronic device1from being excessively bent. That is, the electronic component11may be prevented from being damaged due to the repulsive force generated by the magnetic elements12and13.

FIG.1EandFIG.1Fare schematic diagrams of the electronic device1being bent in accordance with some embodiments of the present disclosure. As stated above, when the flexible body10is bent and the first portion101and the second portion102are moved toward each other, the magnetic elements12and13may generate a repulsive force with each other. As shown inFIG.1EandFIG.1F, the repulsive force generated by the magnetic elements12and13may cause the first portion101and the second portion102to be in a staggered position relative to one another when the flexible body10is bent. That is, the flexible body10cannot be bent along a centerline between the first portion101and the second portion102, and such bending may prevent the electronic component11from being damaged.

FIG.1Gis a schematic diagram of the electronic device being attached to a stand9in accordance with some embodiments of the present disclosure. The stand9is configured to hold the electronic device1. In some embodiments of the present disclosure, the stand9has fixed members92and93.

As shown inFIG.2B, the magnetic elements22may at least partially overlap the interconnection structure25and the magnetic elements23may at least partially overlap the interconnection structure29. Further, the magnetic22and23may not overlap the sensing element271,272.

FIG.2CandFIG.2Dare schematic diagrams of the electronic device2being bent in accordance with some embodiments of the present disclosure. As above mentioned, the substrate208and the protection layer209of the flexible body20of the electronic device2is pliable, and thus the flexible body20of the electronic device2could be bent as shown inFIG.2Cand/orFIG.2D. The first portion201and the second portion202of the flexible body20could be moved relative to each other when the flexible body20of the electronic device2is bent. However, there may be many electronic components integrated in the electronic device2, and thus the electronic components in the electronic device2may be damaged or disabled in case the electronic device2is excessively bent. Especially, the electronic component21which disposed in the first portion201and the second portion202of the flexible body20may be damaged due to the over-bending of the electronic device2.

Referring toFIG.2C, the first portion201and the second portion202are moved toward each other when the flexible body20of the electronic device2is bent. As shown inFIG.2C, a lower surface of the first portion201and a lower surface of the second portion202are moved toward each other, and the end portion221of the magnetic element22and the end portion231of the magnetic element23are moved toward each other as well. As above mentioned, the magnetic polarity of the end portion221of the magnetic element22may be the same as the magnetic polarity of the end portion231of the magnetic element23. Therefore, the magnetic elements22and23may generate a repulsive force with each other when the end portion221of the magnetic element22and the end portion231of the magnetic element23are moved toward each other. Such repulsive force generated by the magnetic elements22and23may resist the relative movement between the first portion201and the second portion202and thus may restrict the electronic device2from being excessively bent. That is, the electronic component21may be prevented from being damaged due to the repulsive force generated by the magnetic elements22and23.

Referring toFIG.2D, the first portion201and the second portion202are moved toward each other when the flexible body20of the electronic device2is bent. As shown inFIG.2D, an upper surface of the first portion201and an upper surface of the second portion202are moved toward each other, and the end portion222of the magnetic element22and the end portion232of the magnetic element23are moved toward each other as well. As above mentioned, the magnetic polarity of the end portion222of the magnetic element22may be the same as the magnetic polarity of the end portion232of the magnetic element23. Therefore, the magnetic elements22and23may generate a repulsive force with each other when the end portion222of the magnetic element22and the end portion232of the magnetic element23are moved toward each other. Such repulsive force generated by the magnetic elements22and23may resist the relative movement between the first portion201and the second portion202and thus may restrict the electronic device2from being excessively bent. That is, the electronic component21may be prevented from being damaged due to the repulsive force generated by the magnetic elements22and23.

FIG.2EandFIG.2Fare schematic diagrams of the electronic device2being bent in accordance with some embodiments of the present disclosure. As stated above, when the flexible body20is bent and the first portion201and the second portion202are moved toward each other, the magnetic elements22and23may generate a repulsive force with each other. As shown inFIG.2EandFIG.2F, the repulsive force generated by the magnetic elements22and23may cause the first portion201and the second portion202to be in a staggered position relative to one another when the flexible body20is bent. That is, the flexible body20cannot be bent along a centerline between the first portion201and the second portion202, and such bending may prevent the electronic component21from being damaged.

In some embodiments of the present disclosure, the stand9has fixed members92and93.
