Nevertheless, in the process of folding the mobile phone, the picture of the display screen may be distorted along with the change of the folding angle, especially in the area where the folding occurs, which may easily affect the user experience. To this end, the present application provides the following examples.

The foldable electronic device 10 of the embodiment of the present application may be a portable device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device. The foldable electronic device 10 includes a flexible display 11, a connection component 12, a functional component 13, a housing 14, and a processor 15, as shown in fig. 2. The connecting assembly 12 is mainly matched with the housing 14 to support the flexible display screen 11, as shown in fig. 1 and 3; and enables the flexible display 11 to be folded as shown in fig. 3. For example, the connecting assembly 12 is hinged to the housing 14 through a rotating shaft, so that the two can rotate relatively; the flexible display screen 11 is connected to the housing 14 through one or a combination of assembling manners such as clamping, gluing, welding, and the like, so that the flexible display screen 11 and the housing 14 can rotate together relative to the connecting assembly 12, thereby folding the flexible display screen 11. The functional component 13 is mainly matched with the flexible display 11 and the connecting component 12 to detect the folding angle of the flexible display 11, so that the foldable electronic device 10 can adjust the display picture thereof according to the folding angle of the flexible display 11. The processor 15 is mainly electrically connected with the flexible display screen 11 and the functional component 13, on one hand, the functional component 13 is controlled to perform the above detection and process the detection information fed back by the functional component 13, and on the other hand, the picture of the flexible display screen 11 is controlled to be matched with the folding angle thereof, so that the picture of the flexible display screen 11 can be adjusted according to the folding angle thereof, and the use experience of the foldable electronic device 10 is improved. Further, structural members such as a battery module, an antenna module, a camera module, and a fingerprint module may be further disposed inside the foldable electronic device 10 (specifically, between the flexible display 11 and the housing 14), so that the foldable electronic device 10 can implement other corresponding functions, thereby meeting the user requirements.

The flexible display screen 11 may be a screen such as an lcd (liquid Crystal display), an OLED (Organic Light-Emitting Diode), a Mini-LED, or a Micro-LED. In the embodiment of the present application, the flexible display screen 11 is taken as an OLED screen for example. Generally, the flexible display 11 includes a transparent cover 111, a display panel 112 and a driving circuit 113, as shown in fig. 2. The transparent cover 111 is mainly used for protecting the display panel 112, and may be used as an outer surface of the foldable electronic device 10, so as to facilitate a user to perform a touch operation such as clicking, sliding, and the like, and also enable the flexible display screen 11 to be bent and folded. The transparent cover 111 may be a flexible film material such as Polyimide (PI) or Colorless Polyimide (CPI). The display panel 112 is mainly used for displaying a screen, and can be used as an interactive interface to instruct a user to perform the touch operation on the transparent cover 111. The display panel 112 may be attached to the transparent cover 111 by using a sealant such as OCA (optical Clear Adhesive) or PSA (Pressure sensitive Adhesive). The driving circuit 113 is generally disposed on a side of the display panel 112 away from the transparent cover 111, and is electrically connected to the display panel 112 and the processor 15, so that the display panel 112 can not only display a picture, but also adjust the display picture according to the folding angle of the flexible display 11, so that the picture of the flexible display 11 can be matched with the folding angle thereof, and the use experience of the foldable electronic device 10 is improved. In some other embodiments, the outer surface of the foldable electronic device 10 (i.e., the outer surface of the transparent cover plate 111) may be further provided with any one of other functional film layers, such as a tempered film, a frosted film, a decoration film, a peep-proof film, a water-condensation film, and the like, so that the foldable electronic device 10 can provide different use effects for users.

Based on the folding line 114 of the flexible display 11, the embodiment of the present application may simply divide the flexible display 11 into the first display portion 115 and the second display 116, as shown in fig. 3. In other words, the flexible display panel 11 includes the first display portion 115 and the second display portion 116, which are integrally formed, and each of which serves as a display area of the flexible display panel 11. The first display portion 115 and the second display portion 116 may be symmetrical with respect to the folding line 114, that is, the size, shape and other parameters of the first display portion and the second display portion may be the same or similar. Further, the folding angle formed by the first display part 115 and the second display part 116 can be folded is theta, wherein 0 & lttheta & gt & lt 180 DEG. When the folding angle θ is equal to 0 °, the flexible display 11 can be considered to be in a folded state; when the folding angle θ is equal to 180 °, the flexible display 11 may be considered to be in the unfolded state; when the folding angle θ is between 0 ° and 180 °, the flexible display 11 can be considered to be in a half-folded state. Therefore, the user can fold the flexible display screen 11 according to the actual use requirement, so that the first display portion 115 and the second display portion 116 are at the corresponding folding angle.

It should be noted that the folding line 114 in the embodiment of the present application is mainly used to illustrate that the first display portion 115 and the second display portion 116 of the flexible display 11 can be folded with respect to an area therebetween (for example, a folding area 117 shown by a dashed line box in fig. 3), and it can also be simply understood that the folding of the flexible display 11 mainly occurs in the folding area 117. Therefore, the folding line 114 is a simple expression and should not be simply interpreted as a general line. Generally, the folding area 117 is specially processed to maintain good structural performance and display performance of the flexible display 11 after thousands of folds, so as to ensure the reliability of the flexible display 11. Further, the integrated structure described in the embodiments of the present application means that the structure of the product is an organic whole, and the product cannot be easily split or divided.

Referring to fig. 4 and 5 together, fig. 4 is a schematic structural view of the connecting assembly in fig. 2, and fig. 5 is an exploded structural view of the connecting assembly in fig. 4.

The connecting assembly 12 includes a base 121, a first connecting member 122 and a second connecting member 123, which can form a wingspan structure similar to birds, so as to facilitate the folding of the flexible display 11.

The base 121 may be disposed along the folding line 114 of the flexible display screen 11, for example, the extending direction of the base 121 is parallel to the direction of the folding line 114, so that the flexible display screen 11 can be folded along the folding line 114 before being assembled with the connecting component 12, the functional component 13, and the housing 14, and can be folded along the folding line 114 relative to the base 121 after being assembled with the above structural components. In other words, the folding of the flexible display 11 occurs in the folding area 117, thereby ensuring the reliability of the flexible display 11. Further, an accommodating space 1211 is formed on a side of the base 121 close to the flexible display 11, as shown in fig. 4. The receiving space 1211 can be used for receiving a portion of the structure of the first connector 122 and the second connector 123, so as to increase the compactness of the foldable electronic device 10; and can also be used as an escape space when the flexible display screen 11 is folded, so that the flexible display screen 11 can be folded relative to the base 121. In the embodiment of the present application, the receiving space 1211 can also be used for disposing the functional component 13, so that the functional component 13 can be detected during the process of folding the flexible display 11, which will be described in detail later.

The first connector 122 and the second connector 123 are respectively located on two opposite sides of the base 121, so that the three form a wingspan structure similar to birds. The first connecting member 122 and the second connecting member 123 are movably connected to the base 121, for example, the first connecting member 122 and the second connecting member 123 can rotate relative to the base 121 in a hinged manner. At this time, the first and

second links

122 and 123 may be individually rotated with respect to the base 121. Further, the first connecting member 122 and the second connecting member 123 are further connected to the flexible display 11 and located on two sides of the folding line 114, that is, the flexible display 11 is connected to the first connecting member 122 and the second connecting member 123, so that the flexible display 11 can be folded after being assembled with the connecting assembly 12. For example, the first connector 122 is connected to the first display portion 115, and the second connector 123 is connected to the second display portion 116, so that the flexible display 11 can rotate relative to the base 121.

Further, the connecting assembly 12 may further include a first adaptor 124 and a second adaptor 125, as shown in fig. 5. The first adaptor 124 and the second adaptor 125 are movably connected to the base 121, for example, the first adaptor 124 and the second adaptor 125 can rotate relative to the base 121 in a hinged manner. The first adapter 124 is further connected to the first connector 122, the second adapter 125 is further connected to the second connector 123, and the first adapter 124 is engaged with the second adapter 125. At this time, one of the first connecting member 122 and the second connecting member 123 rotates relative to the base 121, and the other one is driven to rotate relative to the base 121. With such an arrangement, after the first connecting member 122 and the second connecting member 123 are respectively connected to the flexible display 11 and located on two sides of the folding line 114, that is, after the flexible display 11 is assembled with the connecting member 12, not only can the folding of the flexible display 11 have symmetry and synchronization, but also the flexible display 11 can maintain its folded angle conveniently.

It should be noted that the first connector 122 and the first adapter 124 may be located on one side of the base 121, and the second connector 123 and the second adapter 125 may be located on the other side of the base 121, and they may be symmetrical with respect to the base 121, so that the connecting component 12 and the flexible display 11 may be installed indifferently, thereby increasing the assembly efficiency of the foldable electronic device 10. Further, the connecting members and the adapters may be provided in multiple sets, and they are disposed on the base 121 at intervals in the direction of the folding line 114, as shown in fig. 4, so as to increase the reliability of the flexible display 11 during the folding process.

The housing 14 has a certain structural strength, and is mainly used to protect the foldable electronic device 10 together with the transparent cover 111. The material of the housing 14 may be glass, metal, rigid plastic, etc., or may be made of other electrochromic materials. Further, since the housing 14 is generally directly exposed to the external environment, the material of the housing 14 may preferably have certain properties of wear resistance, corrosion resistance, scratch resistance, etc., or a layer of functional material for wear resistance, corrosion resistance, scratch resistance is coated on the outer surface of the housing 14 (i.e., the outer surface of the foldable electronic device 10).

Based on the above detailed description, the flexible display panel 11 can be simply divided into the first display portion 115 and the second display portion 116 symmetrically disposed with respect to the folding line 114, and the connecting component 12 can also be symmetrically configured with respect to the base 121. Therefore, the housing 14 of the embodiment of the present application may have two identical or similar parts, such as the first housing 141 and the second housing 142, as shown in fig. 2. The first housing 141 may be connected to the first connector 122, and the second housing 142 may be connected to the second connector 123, so that the first housing 141 and the second housing 142 can rotate relative to the base 121. At this time, the first casing 141 and the second casing 142 are located at two sides of the connecting assembly 12, and since the casing 14 is generally a cavity structure, the first casing 141 and the second casing 142 are involuted to form an accommodating space (not shown in fig. 1), so that the connecting assembly 12 is located in the accommodating space when the foldable electronic device 10 is in the unfolded state, that is, the connecting assembly 12 is located inside the foldable electronic device 10, so that the connecting assembly 12 is not visible in fig. 1, and the appearance aesthetic feeling and the holding hand feeling of the foldable electronic device 10 are increased. Further, the flexible display 11 is connected to the first casing 141 and the second casing 142, and the first casing 141 may correspond to the first display portion 115, and the second casing 142 may correspond to the second display portion 116, so that the flexible display 11 can be supported by the casing 14 and the connecting assembly 12, and can be folded. In the embodiment of the present application, the housing 14 may further include a decoration 143, and the decoration 143 is mainly wrapped around the edges of the first display portion 115 and the first housing 141 and the edges of the second display portion 116 and the second housing 142, as shown in fig. 1 to 3, so as to increase the waterproof and dustproof performance, the aesthetic appearance, and the hand-holding feeling of the foldable electronic device 10.

Referring to fig. 4 to 9 together, fig. 6 is a schematic structural view of the flexible display panel and the functional element in fig. 2 along the direction a, fig. 7 is a schematic structural view of the flexible display panel and the functional element in fig. 2 along the direction B, fig. 8 is a schematic structural view of an embodiment of the functional element in fig. 2, and fig. 9 is a schematic structural view of the functional element in fig. 8 in another state. The relative position between the functional element and the detecting element shown in fig. 8 may correspond to the unfolded state of the foldable electronic device (i.e. the folding angle corresponding to the flexible display 11 is equal to 180 °), and the relative position between the functional element and the detecting element shown in fig. 9 may correspond to the folded state of the foldable electronic device (i.e. the folding angle corresponding to the flexible display 11 is equal to 0 °).

The function module 13 includes a function module 131 and a detection module 132. Wherein, the functional element 131 is connected to the flexible display 11, as shown in fig. 6 and 7; the detecting element 132 is disposed in the receiving space 1211 as shown in fig. 4. Based on the above detailed description, when the flexible display 11 is folded, it can be regarded that the first display portion 115 rotates relative to the second display portion 116, and it can also be regarded that the second display portion 116 rotates relative to the first display portion 115, so that the functional piece 131 can be specifically connected with one of the first display portion 115 and the second display portion 116, and thus the functional piece 131 can move along with the folding of the flexible display 11. In addition, since the flexible display 11 is also connected to the housing 14, and the first housing 141 may correspond to the first display portion 115 and the second housing 142 may correspond to the second display portion 116, the functional member 131 may also be connected to one of the first housing 141 and the second housing 142, and the functional member 131 can also be moved following the folding of the flexible display 11. Further, in the foldable electronic device 10, during the folding process, the flexible display 11 and the housing 14 actually move relative to the connecting component 12 (specifically, the base 121), so that the detecting component 132 is disposed in the receiving space 1211 of the base 121, that is, the relative movement between the functional element 131 and the detecting component 132 can be realized. Therefore, in the process of folding the flexible display screen 11, the functional element 131 can be driven to rotate relative to the detection component 132. In this embodiment, the functional element 131 may be a wedge-shaped block, so that different positions of the functional element 131 have different thicknesses, as shown in fig. 6 and 7, so that different positions of the functional element 131 can act on the detection component 132, as shown in fig. 8 and 9, and the detection component 132 can detect the folding angle of the flexible display screen 11. Further, the foldable electronic device 10 can adjust the picture of the flexible display 11 to match with the detected folding angle, thereby improving the use experience of the foldable electronic device 10. The detection of the folding angle of the flexible display 11 is briefly described below:

in some embodiments, the detection assembly 132 includes a cylinder 1321, a piston 1322, and an air pressure sensor 1323. Wherein the cylinder 1321 is connected with the base 121 such that the cylinder 1321 can be fixed with respect to the base 121. One end of the piston 1322 is inserted into the cylinder 1321 so that the piston 1322 and the cylinder 1321 can form a closed space 1324, as shown in fig. 10. In one aspect, the enclosed space 1324 may be pre-filled with an inert gas such as nitrogen, argon, etc. to make the enclosed space 1324 have a certain initial gas pressure; on the other hand, the other end of the piston 1322 away from the cylinder 1321 is close to the functional element 131, so that the other end of the piston 1322 away from the cylinder 1321 can abut against the functional element 131 by the cylinder 1321, as shown in fig. 8 to 10. This is arranged so that piston 1322 is moved relative to cylinder 1321 in the direction of fold line 114 by urging of functional element 131, as indicated by arrow C in fig. 8 and 9, during folding of flexible display 11. Since the air pressure sensor 1323 is disposed in the enclosed space 1324, as shown in fig. 10, the air pressure in the enclosed space 1324 is changed during the movement of the piston 1322 relative to the air cylinder 1321. It is based on this change in gas pressure that the detection assembly 132 is enabled to detect during the folding of the flexible display screen 11.

Further, the detection assembly 132 may also include a bracket 1325 coupled to the base 121, as shown in fig. 8-9. The support 1325 is mainly used for disposing the cylinder 1321 and the piston 1322, and includes a first arm 13251 and a second arm 13252 which are oppositely disposed in the direction of the folding line 114. The cylinder 1321 is connected to the first arm 13251, and the piston 1322 is disposed through the second arm 13252, as shown in fig. 10, such that the cylinder 1321 and the piston 1322 are mounted on the support 1325. In the present embodiment, the piston 1322 and the second arm 13252 may have a clearance fit or a transition fit therebetween to increase the stability of the functional element 131 pushing the piston 1322. Further, the piston 1322 may also be provided with a boss 13221, the boss 13221 being located between the cylinder 1321 and the second arm 13252 to enable the piston 1322 to be stopped by the second arm 13252, thereby controlling the stroke of the piston 1322 and increasing the reliability of the detection assembly 12.

Based on the above detailed description, the processor 15 may be electrically connected to the detection component 132 (specifically, the air pressure sensor 1323) and the flexible display 11 (specifically, the driving circuit 113) by the flexible circuit board. The processor 15 may control the detection component 132 to perform detection, and since the flexible display 11 drives the functional component 131 to push the piston 1322 in the folding process, so as to cause the gas pressure in the air cylinder 1321 to change, the detection may be specifically that the air pressure sensor 1323 detects the air pressure in the enclosed space 1324. Further, the processor 15 may calculate a folding angle of the flexible display 11 according to the detection information (e.g., the air pressure value detected by the air pressure sensor 1323) fed back by the detection component 132, and control the driving circuit 113 to adjust the picture of the display panel 112 according to the folding angle, so that the picture of the flexible display 11 matches with the folding angle thereof, thereby improving the use experience of the foldable electronic device 10. For example, a mathematical relation between the gas pressure of the enclosed space 1324 and the folding angle of the flexible display screen 11 is established in an analog mode; and correcting the mathematical relation by means of actual measurement to increase the accuracy of the detected folding angle, thereby increasing the reliability of the picture adjustment of the flexible display screen 11.

It should be noted that, for the wedge-shaped block, the functional element 131 may have a symmetrical structure as shown in fig. 6 to 10, that is, a gradual structure is formed on one surface 1311 of the functional element 131 close to the detection assembly 132 and on the other surface 1312 of the functional element away from the detection assembly 132, with respect to a normal plane of the flexible display 11. With such an arrangement, not only can the basic requirement that the functional element 131 pushes the piston 1322 be realized, but also the area of the surface 1313 of the functional element 131, which is in contact with the flexible display 11 or the housing 14, can be increased, so that the functional element 131 can be mounted, and thus the reliability of the functional element 131 can be increased. Of course, only one surface 1311 of the functional element 131 close to the detecting element 132 may be of a gradual structure relative to the normal plane of the flexible display screen 11; the structure of the other surface 1312 of the functional element 131 far from the detection assembly 132 is not limited, as shown in fig. 11, as long as the basic requirement of the functional element 131 for pushing the piston 1322 and the requirement of the functional element 131 for installation are satisfied. Further, on the track formed by the functional element 131 acting on the detecting component 132, that is, the track formed by the functional element 131 pushing the piston 1322, the thickness of the functional element 131 may be linearly changed to increase the stability of the functional element 131 pushing the piston 1322, thereby increasing the reliability of the functional component 13. Of course, the basic structure of the functional element 131 itself may be not a wedge-shaped block, but a wedge-shaped groove 1314 may be formed on a surface 1311 of the functional element 131 close to the detecting assembly 132, as shown in fig. 12, and different positions of the wedge-shaped groove 1314 have different depths in the thickness direction of the functional element 131. At this time, one end of the piston 1322 away from the cylinder 1321 abuts against the wedge-shaped groove 1314, and the functional element 131 can push the piston 1322 due to the different depths of the wedge-shaped groove 1314. Accordingly, in the track formed by the wedge-shaped groove 1314 acting on the detecting component 132, that is, the track formed by the functional component 131 pushing the piston 1322, the depth of the wedge-shaped groove 1314 in the thickness of the functional component 131 can also be changed linearly, which can also increase the stability of the functional component 131 pushing the piston 1322, thereby increasing the reliability of the functional component 13.

Referring to fig. 13 to 14 together, fig. 13 is a schematic structural diagram of another embodiment of the functional device in fig. 2, and fig. 14 is a schematic structural diagram of the functional device in fig. 13 in another state. In which the relative position of the functional element and the detecting component shown in fig. 13 may correspond to the unfolded state of the foldable electronic device (i.e. the folding angle corresponding to the flexible display 11 is equal to 180 °), and the relative position of the functional element and the detecting component shown in fig. 14 may correspond to the folded state of the foldable electronic device (i.e. the folding angle corresponding to the flexible display 11 is equal to 0 °).

The main differences from the above embodiments are: in this embodiment, the detection unit 132 includes a hall sensor 1326 and a magnet 1327 that are provided to face each other in the direction of the folding line 114. Wherein the hall sensor 1326 primarily senses the magnetic field strength of the magnet 1327; the magnet 1327 may be a permanent magnet or an electromagnet, and is not limited herein. Further, one of the hall sensor 1326 and the magnet 1327 is movably connected to the base 121 and abuts against the functional member 131, and the other is fixed to the base 132, so that the functional member 131 can push the hall sensor 1326 or the magnet 1327 along the direction of the folding line 114 during the folding process of the flexible display screen 11. For example, the hall sensor 1326 is connected to the base 121 such that the hall sensor 1326 is stationary with respect to the base 121; and the magnet 1327 is movably connected to the base 121 so that the magnet 1327 moves relative to the hall sensor 1326 in the direction of the folding line 114, as indicated by an arrow D in fig. 13 and 14, under the pushing of the functional member 131. So configured, when the function piece 131 pushes the magnet 1327 close to the hall sensor 1326, the magnetic field strength detected by the hall sensor 1326 becomes stronger; conversely, when the magnet 1327 is away from the hall sensor 1326, the intensity of the magnetic field detected by the hall sensor 1326 is then weakened. It is based on this change in magnetic field strength that the detection assembly 132 is able to detect during the folding of the flexible display screen 11.

For example, the detecting assembly 132 further includes a fixed plate 1328, a movable plate 1329 and an elastic member 13210. The fixing plate 1328 is connected to the base 121 so that the fixing plate 1328 can be fixed with respect to the base 121. One end of the elastic member 13210 is connected to the fixed plate 1328, and the other end of the elastic member 13210 is connected to the movable plate 1329, so that the movable plate 1329 can move with respect to the fixed plate 1328. At this time, the elastic member 13210 may be a spring; and may have a certain amount of initial deformation so that the movable plate 1329 can abut against the function piece 131. With this arrangement, the hall sensor 1326 may be disposed on the fixing plate 132, and the magnet 1327 may be disposed on the movable plate 1329, so that during the folding process of the flexible display 11, the movable plate 1329 is pushed by the functional element 131 to approach or separate from the fixing plate 1328 along the direction of the folding line 114, thereby driving the magnet 1327 to approach or separate from the hall sensor 1326. In addition, by means of the elastic element 13210 cooperating with the functional element 131, the stability of the functional element 131 pushing the movable plate 1329 can be increased, thereby increasing the reliability of the detecting assembly 12.

Further, the detecting component 132 may further include a support 1325 and a push rod 13211 disposed between the movable plate 1329 and the functional element 131, and both of them mainly transmit the thrust between the functional element 131 and the movable plate 1329. The bracket 1325 is connected to the base 121, the push rod 13211 is disposed through the bracket 1325, one end of the push rod 13211 abuts against the movable plate 1329, and the other end of the push rod 13211 abuts against the functional component 131, so that the push rod 13211 can push the movable plate 1329 under the action of the functional component 131. Further, the push rod 13211 and the movable plate 1329 may be an integrally formed structural member, and may also be connected by one or a combination of assembling manners such as glue joint, clamping joint, welding, and threads, so that the movable plate 1329 may be mounted, and the stroke of the movable plate 1329 may be controlled by the bracket 1325, thereby increasing the reliability of the detection assembly 12. In the embodiment of the present application, the pushing rod 13211 and the bracket 1325 may be in a clearance fit or a transition fit, so as to increase the stability of the functional component 131 pushing the pushing rod 13211.

Similarly, the processor 15 may be electrically connected to the detection assembly 132 (specifically, the hall sensor 1326) and the flexible display 11 by a flexible circuit board. Wherein, the processor 15 can control the detection component 132 to detect, because the flexible display screen 11 can drive the functional component 131 to push the magnet 1327 in the folding process, and further cause the magnetic field intensity sensed by the hall sensor 1326 to change, the above-mentioned detection can be specifically the magnetic strength of the hall sensor 1323 detection magnet 1327. Further, the processor 15 may calculate a folding angle of the flexible display 11 according to the detection information fed back by the detection component 132 (for example, the magnetic field strength detected by the hall sensor 1326), and control the driving circuit 113 to adjust the picture of the display panel 112 according to the folding angle, so that the picture of the flexible display 11 matches with the folding angle thereof, thereby improving the use experience of the foldable electronic device 10. For example, a mathematical relation between the magnetic strength sensed by the hall sensor 1326 and the folding angle of the flexible display screen 11 is established in an analog mode; and correcting the mathematical relation by means of actual measurement to increase the accuracy of the detected folding angle, thereby increasing the reliability of the picture adjustment of the flexible display screen 11.

The functional element 131 in the present embodiment may be a wedge-shaped block as shown in fig. 7 or fig. 11, or may have a structure in which a wedge-shaped groove 1314 is formed on one surface as shown in fig. 12. Further, other structures in this embodiment are the same as or similar to those in the above embodiment, and specific reference may be made to the detailed description of the above embodiment, which is not repeated herein.

Referring to fig. 15 to 16 together, fig. 15 is a schematic structural diagram of another embodiment of the functional device in fig. 2, and fig. 16 is a schematic structural diagram of the functional device in fig. 15 in another state. In which the relative position of the functional element and the detecting component shown in fig. 15 may correspond to the unfolded state of the foldable electronic device (i.e. the folding angle corresponding to the flexible display 11 is equal to 180 °), and the relative position of the functional element and the detecting component shown in fig. 16 may correspond to the folded state of the foldable electronic device (i.e. the folding angle corresponding to the flexible display 11 is equal to 0 °).

The main differences from the above embodiments are: in this embodiment, the detecting element 132 includes a fixed plate 1328, a movable plate 1329, an elastic member 13210, and a distance sensor 13212. The fixing plate 1328 is coupled to the base such that the fixing plate 1328 is fixed with respect to the base 121. One end of the elastic member 13210 is connected to the fixed plate 1328, and the other end of the elastic member 13210 is connected to the movable plate 1329, so that the movable plate 1329 can move with respect to the fixed plate 1328. At this time, the elastic member 13210 may be a spring; and may have a certain amount of initial deformation so that the movable plate 1329 can abut against the function piece 131. Further, the distance sensor 13212 may be disposed on a side of the fixed plate 1328 close to the movable plate 1329, and may also be disposed on a side of the movable plate 1329 close to the fixed plate 1328, so that the movable plate 1329 is pushed by the functional element 131 to approach or separate from the fixed plate 1328 along the direction of the folding line 114 during the folding process of the flexible display 11, as shown by an arrow E in fig. 15 and 16. So configured, when the functional element 131 pushes the movable plate 1329 to approach the fixed plate 1328, the distance detected by the distance sensor 13212 is decreased; on the contrary, when the movable plate 1329 is far away from the fixed plate 1328, the distance detected by the distance sensor 13212 is increased. It is based on this change in distance that the detection assembly 132 is able to detect during the folding of the flexible display screen 11.

Further, the detecting assembly 132 may further include a reflective sheet 13213, and the reflective sheet 13213 is mainly used to replace the movable plate 1329 to reflect the incident light emitted by the distance sensor 13212, so as to avoid light loss, and further increase the reliability of the detecting process. The reflective sheet 13213 may be one of a metal reflective film, an all dielectric reflective film, and a metal dielectric reflective film, which is not limited herein.

Similarly, the processor 15 may be electrically connected to the detection component 132 (specifically, the distance sensor 13212) and the flexible display 11 via the flexible circuit board. The processor 15 may control the detection assembly 132 to perform detection, and since the flexible display 11 drives the functional element 131 to push the movable plate 1329 in the folding process, so as to change the distance detected by the distance sensor 13212, the detection may be specifically that the distance sensor 13212 detects the distance between the movable plate 1329 and the fixed plate 1328. Further, the processor 15 may calculate a folding angle of the flexible display 11 according to the detection information fed back by the detection component 132 (e.g., the distance between the two panels detected by the distance sensor 13212), and control the driving circuit 113 to adjust the picture of the display panel 112 according to the folding angle, so that the picture of the flexible display 11 matches with the folding angle thereof, thereby improving the use experience of the foldable electronic device 10. For example, a mathematical relation between the distance between the movable plate 1329 and the fixed plate 1328 and the folding angle of the flexible display 11 is established in an analog mode; and correcting the mathematical relation by means of actual measurement to increase the accuracy of the detected folding angle, thereby increasing the reliability of the picture adjustment of the flexible display screen 11.
