[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0021] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, specific embodiments and application scenarios.

[0022] Referring to FIGS. 1-5, the disclosed folding screen assembly of an electronic device includes a folding screen 100, a crease detection assembly 200, and a repair assembly. The electronic device can be a mobile phone, a tablet computer, a smart wearable device, etc.

[0023] Referring to FIG. 1, the folding screen 100 is a display and operation component of the electronic device. The folding screen 100 can have a folding area 110 to enable folding or flattening of the folding screen 100. In addition, the folding screen 100 can have display areas, i.e., a first display area 120 and a second display area 130. The first display area 120 and the second display area 130 are respectively located on both sides of the folding area 110 and can rotate relative to each other about a rotation shaft 400. The rotation shaft 400 is arranged corresponding to the folding area 110.

[0024] During use of the electronic device by a user, the folding screen 100 in an unfolded state can provide a larger range for the user to view and operate, thereby improving the user experience. When the user does not need to use the electronic device, folding can be achieved to reduce the size of the electronic device, thereby facilitating carrying or storage.

[0025] In some embodiments, the folding screen 100 can be made of a flexible material to enable folding or flattening. Considering that the folding area 110 can have creases after a period of folding and unfolding operations of the folding screen 100, the creases can be repaired to weaken the creases to the greatest extent and maintain the flatness of the folding area 110, so as to prolong the service life of the folding screen 100 and reduce the impact of the creases on the user's viewing or operation of the electronic device.

[0026] Exemplarily, the folding screen 100 can adopt a memory material, which can be repaired in the case of a crease. The memory material can include a memory metal, such as a memory metal film, and the like. The memory material can also be a memory polymer material, such as polystyrene, polyurethane, and the like. Of course, other materials can also be used, which are not limited herein. It should be noted that the principle of restoring the shape of the memory material can refer to the prior art.

[0027] The crease detection assembly 200 plays a role in detecting the crease. In some embodiments, the crease detection assembly 200 is arranged on the side of the folding screen 100 away from the display surface and corresponds to the folding area 110, and is used to detect the crease deformation amount at different positions in the folding area 110. After the electronic device is used for a period of time, the folding area 110 of the folding screen 100 can have a crease. In this case, the crease detection assembly 200 can detect the crease at different positions of the folding area 110 to obtain the crease deformation amount at different positions in the folding area 110. Exemplarily, the crease detection assembly 200 can adopt a layer structure, i.e., a crease detection layer, which can be beneficial to reduce the occupied space.

[0028] In some embodiments, the crease detection assembly 200 can be connected to the folding screen 100 to ensure the stability of the crease detection assembly 200. Exemplarily, the crease detection assembly 200 is bonded to the side of the folding screen 100 away from the display surface. Of course, other connection methods can also be used, such as clamping, pressure bonding, and the like. The crease detection assembly 200 can be bonded to the side of the folding screen 100 away from the display surface by using Optically Clear Adhesive (OCA) glue.

[0029] In other embodiments, the crease detection assembly 200 and the folding screen 100 can also share a substrate, i.e., the crease detection assembly 200 is prepared on the PI substrate of the folding screen 100 to realize the sharing of the PI substrate. This method can not only save materials, but also reduce the overall thickness of the folding screen assembly, thereby providing more installation space for other structures of the electronic device.

[0030] In some embodiments, the crease detection assembly 200 can include a resistive strain gauge. The resistive strain gauge can be made of a metal material, which includes a base material, a metal strain wire or strain foil, a polyimide (PI) substrate, and a lead wire, and the like.

[0031] Exemplarily, the crease detection component 200 can include a plurality of resistive strain gauges, each of which can correspond to a certain position within the folding area 110; of course, the crease detection component 200 can also include an integral resistive strain gauge, which can correspond to a plurality of different positions within the folding area 110. Regardless of which way the crease detection component 200 adopts, the crease deformation of different positions within the folding area 110 can be detected. It should be noted here that the specific structure of the resistive strain gauge and its working principle can also refer to the prior art, which will not be described in detail here.

[0032] Among them, the sensitive grid of the metal wire strain gauge is composed of parallelly arranged resistance wires; the metal foil strain gauge is made of very thin metal foil sensitive grid on the PI substrate through photoetching, etching and other processes, the size is generally 10 μm or smaller, which can well deform with the folding screen 100, and the heat conduction condition is better, of course, the PI substrate can also be shared with the folding screen 100.

[0033] The repair component is arranged on the side of the folding screen 100 away from the display surface and is arranged corresponding to the folding area 110, and is used for repairing at least part of the folding area 110, so as to repair at least part of the creases of the folding area 110.

[0034] Exemplarily, the repair component can adopt a layer structure, which can be beneficial to reduce the occupied space.

[0035] In the embodiment of the application, the repair component is used to repair the creases at the corresponding positions when the crease deformation of at least part of the positions within the folding area 110 exceeds the set threshold. Based on this setting, after the electronic device is used for a period of time, the folding area 110 can have creases, and the crease deformation of different positions within the folding area 110 can be detected by the crease detection component 200. When the crease deformation of at least part of the positions within the folding area 110 exceeds the set threshold, the repair component is started to repair at least part of the positions, so that at least part of the positions starts to recover to the flat state, and finally the crease deformation of at least part of the positions is reduced to within the range of the set threshold, so that the folding area 110 can be basically restored to the original state.

[0036] It should be noted here that after the repair, the crease deformation of at least part of the positions can be reduced to 0, of course, it can also be reduced to a certain value between 0 and the set threshold, which can be determined according to the crease condition. For example, after the electronic device is used for a relatively long time, the crease is relatively deep, and after the repair, the crease deformation is reduced to a certain value between 0 and the set threshold; when the electronic device is used for a relatively short time, the crease is relatively shallow, and after the repair, the crease deformation can be basically reduced to 0.

[0037] In some embodiments, the repairing assembly can be fixedly connected to the folding screen 100 to ensure the stability of the repairing assembly. For example, the repairing assembly can be bonded to the side of the folding screen 100 away from the display surface, and other fixing methods such as clamping and pressure bonding can also be used. The repairing assembly can be bonded to the side of the folding screen 100 away from the display surface by using Optically Clear Adhesive (OCA) glue.

[0038] In other embodiments, the repairing assembly and the folding screen 100 can also share a substrate, which can save materials and reduce the overall thickness of the folding screen assembly, thereby providing more installation space for other structures of the electronic device.

[0039] In some embodiments, the repairing assembly can be prepared on the PI substrate by using photolithography, etching, vapor deposition and other processes to prepare a circuit, so that the repairing assembly can well deform with the folding screen 100. Of course, the repairing assembly can also be prepared on the PI substrate of the folding screen 100 to realize the sharing of the PI substrate.

[0040] In some embodiments, the repairing assembly can be connected to the side of the folding screen 100 away from the display surface, and the fold detection assembly 200 can be connected to the side of the repairing assembly away from the folding screen 100. Based on this arrangement, the folding screen 100 can be repaired more effectively by the assemblies.

[0041] In other embodiments, the fold detection assembly 200 can be connected to the side of the folding screen 100 away from the display surface, and the repairing assembly can be connected to the side of the fold detection assembly 200 away from the folding screen 100, as shown in FIG. 2. This arrangement can also detect the fold deformation of different positions in the folding area 110 of the folding screen 100 and repair the corresponding positions, thereby achieving accurate repair effect.

[0042] In some embodiments, the projections of the fold detection assembly 200 and the repairing assembly in the thickness direction of the folding screen 100 overlap at least part of the folding area 110, so that the fold deformation of at least part of the positions in the folding area 110 can be detected and repaired.

[0043] In some embodiments, the projections of the fold detection assembly 200, the repairing assembly and the folding area 110 in the thickness direction of the folding screen 100 can completely coincide, so that the fold deformation of all positions of the folding area 110 can be detected and repaired.

[0044] The embodiment of the present application can obtain a plurality of data pairs between positions and crease deformation amounts by detecting the crease deformation amounts of different positions in the folding area 110, and repair the creases of the corresponding positions when the crease deformation amounts of at least some positions exceed the set threshold. Therefore, the embodiment of the present application can more accurately repair the creases of different positions of the folding area 110, so that the creases can be repaired well to alleviate the problem of unevenness or even breakage of the folding area 110 of the folding screen 100, prolong the service life of the folding screen 100, and improve the appearance display effect of the folding screen 100.

[0045] To obtain the crease deformation amounts of different positions in the folding area 110 of the folding screen 100, the resistance strain gauge is set on the side of the folding screen 100 away from the display surface, and the working principle is based on the strain effect, that is, the resistance value of the conductor material or semiconductor material will change when it is mechanically deformed under external force. Since the folding screen 100 is prone to creases in the folding area 110 close to the hinge shaft 400, it is only necessary to arrange the crease detection assembly 200 at least at some positions of the folding area 110.

[0046] The coordinate system of the folding area 110 is shown in FIG. 5. A certain voltage is applied to both ends of the resistance strain gauge, the current change of the resistance strain gauge at different positions in the folding area 110 is detected, and the crease deformation amount at different positions in the folding area 110 can be obtained by calculation. The correspondence between the coordinates of different positions and the corresponding crease deformation amounts can be stored in the register. For example, the crease deformation amount L0 corresponding to the coordinate value (X0, Y0), the crease deformation amount L1 corresponding to the coordinate value (X1, Y1), and so on.

[0047] In the embodiment of the present application, the triggering condition of the crease detection can include the following cases:

[0048] The first case is that the crease detection assembly 200 can automatically detect periodically at certain time intervals when the folding screen 100 is in the flat state.

[0049] The second case is that the user can manually trigger the detection or the user can adjust the detection frequency.

[0050] The third case is that the folding number of the folding screen 100 can be detected and counted by a sensor, and the detection can be started when the folding number exceeds the number threshold.

[0051] In the fourth case, the folding number n of the folding screen 100 can be detected and counted by the sensor, and the detection frequency t can be adjusted in a stepwise manner based on the folding number. As shown in Table 1, the threshold values of the folding number are set as n1, n2, n3, and the corresponding crease detection frequencies are t1, t2, t3. Here, n1 < n2 < n3, and t1 < t2 < t3, which is more in line with the rule that the more the folding number, the more serious the crease.

[0052] Table 1 shows the relationship between the folding number and the folding frequency

[0053] In the embodiments of the present application, the folding area 110 can include a plurality of pixel points, which are distributed in a coordinate system composed of the X-axis and the Y-axis, wherein the X-axis direction is perpendicular to the crease direction of the folding area 110, and the Y-axis direction is parallel to the crease direction, and both the X-axis direction and the Y-axis direction are perpendicular to the thickness direction of the folding screen 100.

[0054] In some embodiments, the length dimension of the electronic device is greater than the width dimension, and the length dimension can be reduced by folding, wherein the X-axis direction can be the length direction of the electronic device, and the Y-axis direction can be the width direction of the electronic device.

[0055] To repair at least part of the plurality of pixel points in the folding area 110, in the embodiments of the present application, the repair assembly can include a plurality of circuits, which are staggered in the coordinate system to form a plurality of staggered points 330, and the plurality of staggered points 330 are one-to-one corresponding to the plurality of pixel points, so as to repair the positions corresponding to the plurality of pixel points respectively by the repair assembly. Based on this arrangement, the positions corresponding to the plurality of pixel points in the folding area 110 can be repaired respectively by the plurality of staggered points 330 of the repair assembly, so as to improve the position accuracy of the repaired positions and improve the repair efficiency.

[0056] In addition, the crease detection assembly 200 and the plurality of pixel points can be respectively arranged to detect the crease deformation of the positions corresponding to the plurality of pixel points, so as to improve the detection accuracy of the crease positions, thereby laying a foundation for subsequent repair of the corresponding crease positions.

[0057] In some embodiments, the crease detection assembly 200 can include a plurality of strain gauges, and the plurality of strain gauges are one-to-one corresponding to the plurality of pixel points, so as to detect the crease deformation of the positions corresponding to the plurality of pixel points respectively by the plurality of strain gauges.

[0058] Based on the above setting, in the embodiment of the present application, the folding area 110, the crease detection assembly 200 and the repair assembly are respectively divided into multiple parts and are respectively set correspondingly, so that the deformation amount of the crease at different positions in the folding area 110 can be accurately detected, and then the accurate repair of different positions can be realized, so as to improve the repair efficiency.

[0059] Of course, in other embodiments, the multiple pixel points in the folding area 110, the multiple repair points (i.e., the staggered points 330) of the repair assembly and the multiple detection points of the crease detection assembly 200 can adopt other arrangement forms, such as a multi-circle annular arrangement mode, etc., as long as the deformation amount of the crease at different positions in the folding area 110 can be detected and the corresponding heating of different positions can be performed, and the specific distribution form is not limited.

[0060] In the embodiment of the present application, a certain threshold value can be set for the crease deformation amount and the corresponding coordinate position, so as to start the repair mode, which specifically includes:

[0061] In the case that at least part of the crease deformation amount in the folding area 110 exceeds the set threshold value, the coordinate position with the deformation amount exceeding the standard is started to be recorded, and the number is counted. Since the wrinkle of the folding area 110 of the folding screen 100 has a greater influence on the display effect, the coordinate position with the deformation amount exceeding the standard can be set with a certain range threshold value.

[0062] The first form is shown in FIG. 5. In the case that the coordinate X of the coordinate position with the deformation amount exceeding the standard in the direction perpendicular to the crease direction satisfies X0≤X≤X1, the number of the coordinate positions with the deformation amount exceeding the standard is counted, wherein X0X1; and then in the case that the number of the coordinate positions with the deformation amount exceeding the standard exceeds the first preset number, the repair mode is started to repair the area where the coordinate position with the deformation amount exceeding the standard is located. On the contrary, in the case that the number of the coordinate positions with the deformation amount exceeding the standard does not exceed the first preset number, the repair is stopped.

[0063] The second form is that in the case that the coordinate Y of the coordinate position with the deformation amount exceeding the standard in the direction parallel to the crease direction satisfies Y0≤Y≤Y1, the number of the coordinate positions with the deformation amount exceeding the standard is counted, wherein Y0Y1; and then in the case that the number of the coordinate positions with the deformation amount exceeding the standard exceeds the first preset number, the heating repair mode is started to heat the area where the coordinate position with the deformation amount exceeding the standard is located. On the contrary, in the case that the number of the coordinate positions with the deformation amount exceeding the standard does not exceed the first preset number, the heating is stopped.

[0064] In the third form, the coordinate position of the deformation exceeding the standard is in the coordinate X perpendicular to the crease direction and satisfies X0≤X≤X1, and the coordinate Y parallel to the crease direction satisfies Y0≤Y≤Y1, and the number of coordinate positions of the deformation exceeding the standard is counted, wherein X0X1, Y0Y1; in the case that the number of coordinate positions of the deformation exceeding the standard exceeds the first preset number, the repair mode is started to repair the area where the coordinate positions of the deformation exceeding the standard are located. On the contrary, in the case that the number of coordinate positions of the deformation exceeding the standard does not exceed the first preset number, the repair is stopped.

[0065] In the fourth form, in the case that the number of coordinate positions of the deformation exceeding the standard arranged continuously in a certain direction in the coordinate system composed of the X axis perpendicular to the crease direction and the Y axis parallel to the crease direction exceeds the second preset number, the area where the coordinate positions of the deformation exceeding the standard are located is repaired respectively to start the repair mode.

[0066] Referring to FIG. 3, in some embodiments, the repair assembly can be a heating assembly 300, which includes a plurality of circuits, which can include a plurality of heating circuits 310 (i.e., Heat circuits) and a plurality of gate circuits 320 (i.e., Gate circuits), wherein the plurality of heating circuits 310 can be arranged along one of the X axis direction or the Y axis direction, and each heating circuit 310 extends along the other one of the X axis direction and the Y axis direction; the plurality of gate circuits 320 are arranged along the other one of the X axis direction and the Y axis direction, and each gate circuit 320 extends along one of the X axis direction and the Y axis direction; the plurality of heating circuits 310 and the plurality of gate circuits 320 are staggered to form a plurality of staggered points 330. Based on this arrangement, a longitudinal and transverse staggered circuit can be formed by the plurality of heating circuits 310 and the plurality of gate circuits 320, and the plurality of gate circuits 320 respectively play a control role, and the plurality of heating circuits 310 respectively play a heating role, so as to heat the positions corresponding to the plurality of staggered points 330 by the heating assembly 300.

[0067] In some embodiments, a transistor and a heating resistor are provided at each staggered point 330 to play a switching control role by the transistor and heat the corresponding position by the heating resistor.

[0068] In other embodiments, considering that the cost of the transistor is relatively high, in order to reduce the cost, the transistor can not be used, but the corresponding positions of the plurality of staggered points 330 can be heated by a software control mode according to the read position coordinate data.

[0069] As shown in FIG. 4, a high level is applied to the G1 circuit (i.e., Gate1 circuit), and then the transistor on this circuit is controlled to be open; a low level is applied to the G2 circuit (i.e., Gate2 circuit), and then the transistor on this circuit is controlled to be closed. On the premise that the transistor on the G1 circuit is open, a voltage is applied to the H0 circuit (i.e., Heat0 circuit), the H1 circuit (i.e., Heat1 circuit), and the H2 circuit (i.e., Heat2 circuit), and then a current passes through the heating resistor on the corresponding intersection point 330, and at this time, the corresponding heating resistor emits heat according to Q = T * U 2 / R, where Q is the generated heat, T is the time of power-on, U is the voltage applied to the heating circuit 310, and R is the resistance value of the heating resistor. By controlling the size of the voltage applied to the different heating circuits 310 and the power-on time, the heat generated by each intersection point 330 can be controlled.

[0070] In some embodiments, in the repair mode, the coordinate values of the crease corresponding to the crease deformation exceeding the set threshold are read from the register, and the crease deformation L corresponding to the coordinate values (X, Y) is read. It should be noted that the coordinate values of the plurality of intersection points 330 in the folding area 110 can be pre-stored in the register, and the data of the crease deformation of different positions in the folding area 110 detected by the crease detection assembly 200 can also be stored in the register. In the case of entering the repair mode, the coordinate values of the corresponding positions and the corresponding crease deformations can be read from the register.

[0071] Wherein, the coordinate Y value is used to determine which gate circuit 320 needs to be applied with a high level, the X value is used to determine which heating circuit 310 needs to be applied with a voltage, and the deformation L is used to determine the high and / or time length of the voltage applied to the heating circuit 310. The greater the deformation L, the higher the voltage applied to the heating circuit 310 and / or the longer the time length of the applied voltage, so as to make the position with greater crease deformation obtain more heat, thereby obtaining better repair.

[0072] The generated heat can be calculated according to Q = T * U 2 / R, in order to make different positions generate different heat, the voltage value of the applied voltage can be fixed, and different power-on time lengths can be applied; of course, the power-on time length can also be unified, and the voltage values of the voltages applied to different positions can be different.

[0073] In some embodiments, in the repair mode, the crease detection component 200 can increase the frequency of crease detection, for example, in the normal use mode, the crease detection is performed once every 10 minutes; in the repair mode, the crease detection component 200 can perform the crease detection once every 1 second until the crease deformation of at least part of the position reaches the set threshold range and stops.

[0074] In some embodiments, in the repair mode, if the number of coordinate positions whose crease deformation exceeds the set threshold value does not exceed the first preset number, the repair is stopped to achieve more accurate control of the repair effect.

[0075] Considering that in the heating repair mode, the external environment temperature also affects the heat dissipation speed of the folding screen 100, the folding screen assembly in the embodiments of the present application can further include a temperature detection element for detecting the external environment temperature. Exemplarily, the temperature detection element can be a temperature sensor, and of course, can also be other forms, which are not limited here.

[0076] In the embodiments of the present application, the repair component can be a heating component 300, which can be used to change at least one of the heating voltage (i.e., the applied voltage) and the heating time (i.e., the power-on time) according to the external environment temperature detected by the temperature detection element. Based on this, the folding screen assembly can still achieve a relatively stable heating repair effect under different external environment temperatures.

[0077] Specifically, at least one of the voltage amplitude applied to the heating circuit 310 and the heating time is adjusted according to the external environment temperature. For example, the lower the external environment temperature, the higher the voltage amplitude applied to the heating circuit 310 and the longer the heating time; on the contrary, the higher the external environment temperature, the lower the voltage amplitude applied to the heating circuit 310 and the shorter the heating time. Based on this, good heating repair effect can be achieved under different external environment temperatures.

[0078] In addition, when repairing the folding screen 100, the heating balance should also be considered, so the voltage applied to the heating circuit 310 can be slowly increased, so that the temperature of each position slowly rises to a suitable value, so as to avoid the occurrence of the situation that the temperature difference of each position is large when the heating starts, which causes the folding screen 100 to be heated unevenly. Therefore, it can prevent the folding screen 100 from having a local temperature that is too high or too low, which adversely affects the repair effect.

[0079] The repair assembly is the heating assembly 300. To alleviate the impact of the heating assembly 300 on other components of the electronic device, a heat insulation design can be added. The folding screen assembly can further include a heat insulation element arranged in the interior of the electronic device and located between the heating assembly 300 and the structural components of the electronic device. In this way, the heat generated by the heating assembly 300 can be effectively blocked from being transmitted to other structural components to cause the other structural components to heat up. For example, the heat insulation element can be a heat insulation pad, a heat insulation layer, or the like.

[0080] To avoid the impact of the repair process on the user, the user can be reminded through a pop-up window, or the repair can be performed during a period when the user does not use the electronic device and the folding screen 100 is in the unfolded state based on the statistics of the user's use time period, so as to reduce the user's perception.

[0081] The embodiments of the present application also disclose a repair method of a folding screen 100, which is applied to an electronic device. The repair method can correspond to the folding screen assembly of the electronic device, so as to repair the folding screen assembly. The folding screen 100 has a folding area 110. It should be noted that there is no technical obstacle between the technical solutions involved in the repair method and the technical solutions involved in the folding screen assembly, and the technical solutions can be associated with or cross-used with each other.

[0082] Referring to FIGS. 1 to 7, the disclosed repair method includes the following steps.

[0083] In step S100, the crease deformation amounts at different positions in the folding area 110 are detected.

[0084] In some embodiments, the crease detection assembly 200 can be used to detect the crease deformation amounts at different positions in the folding area 110, so as to obtain the crease conditions at the different positions.

[0085] The crease detection assembly 200 and the plurality of pixel points in the folding area 110 can be respectively arranged to detect the crease deformation amounts at the positions corresponding to the plurality of pixel points, respectively. In this way, the detection accuracy of the crease positions can be improved, thereby laying a foundation for subsequent repair of the corresponding crease positions.

[0086] For example, the crease detection assembly 200 can include a strain gauge, such as a resistance strain gauge or the like.

[0087] Further, in step S200, when the crease deformation amounts at at least some positions exceed a set threshold value, the corresponding positions are repaired to repair the creases at the corresponding positions.

[0088] In some embodiments, the repair assembly can be used to achieve the repair effect at different positions in the folding area 110.

[0089] The embodiment of the present application can obtain a plurality of data pairs between positions and the crease deformation amount by detecting the crease deformation amount of different positions in the folding area 110, and in the case that the crease deformation amount of at least part of the positions exceeds the set threshold value, the corresponding positions are repaired to realize the crease repair of the corresponding positions. Therefore, the embodiment of the present application can more accurately repair the creases of different positions of the folding area 110, so that the creases can be repaired to a good effect, thereby alleviating the problem of unevenness or even breakage of the folding area 110 of the folding screen 100, prolonging the service life of the folding screen 100, and improving the appearance display effect of the folding screen.

[0090] In some embodiments, detecting the crease deformation amount of different positions in the folding area 110 comprises:

[0091] Detecting the current change of the crease detection assembly 200 at different positions in the folding area 110; and obtaining the crease deformation amount corresponding to different positions respectively according to the current change.

[0092] For example, a resistive strain gauge is applied with a certain voltage at both ends, and the current change of the resistive strain gauge at different positions is detected, and the size of the crease deformation amount of the folding area 110 at different positions can be obtained by calculation.

[0093] In addition, the corresponding relationship between the coordinate values of different positions and the crease deformation amount can be stored in the register to lay a foundation for subsequent multi-point repair.

[0094] In some embodiments, detecting the crease deformation amount of different positions in the folding area 110 comprises:

[0095] Periodically detecting the crease deformation amount of different positions in the folding area 110.

[0096] Specifically, the crease detection assembly 200 can automatically periodically detect at intervals in the flat state of the folding sheet, so as to obtain the crease deformation amount of different positions in the folding area 110, thereby laying a foundation for subsequent judgment of whether the crease deformation amount exceeds the standard.

[0097] In some embodiments, detecting the crease deformation amount of different positions in the folding area 110 comprises: detecting the crease deformation amount of different positions in the folding area 110 in the case that a detection instruction is received.

[0098] Specifically, the detection instruction can be input in a manual manner, and the detection process is triggered in the case that the electronic device receives the detection instruction input by the user.

[0099] In some embodiments, detecting the crease deformation amount of different positions in the folding area 110 comprises: detecting the folding times of the folding screen 100; and automatically triggering the detection of the crease deformation amount of different positions in the folding area 110 when the folding times exceed a threshold value.

[0100] Specifically, the folding times of the folding screen 100 can be detected and counted by the sensor, and the detection process can be triggered after the folding times exceed a times threshold.

[0101] In some embodiments, detecting the crease deformation amount of different positions in the folding area 110 further comprises: adjusting the detection frequency of the crease deformation amount of different positions in the folding area 110 in a stepwise manner based on the folding times.

[0102] Specifically, the folding times n of the folding screen 100 can be detected and counted by the sensor, and the detection frequency t can be adjusted in a stepwise manner based on the folding times. For example, the times threshold of the stepwise folding times is set as n1, n2, n3…, and the corresponding crease detection frequency is t1, t2, t3…, where n1 < n2 < n3 and t1 < t2 < t3, which is more in line with the rule that the more folding times, the more serious the crease.

[0103] In some embodiments, detecting the crease deformation amount of different positions in the folding area 110 comprises: the detection frequency of the crease deformation amount in the repair mode is greater than the detection frequency of the crease deformation amount in the non-repair mode.

[0104] Specifically, in the repair mode, the crease detection component 200 can increase the frequency of crease detection. For example, in the normal use mode, the crease detection is performed once every 10 minutes; in the repair mode, the crease detection component 200 can perform the crease detection once every second until the crease deformation amount of at least part of the positions reaches the set threshold range and stops repairing.

[0105] In some embodiments, repairing the corresponding position when the crease deformation amount of at least part of the positions exceeds the set threshold value comprises: recording the coordinate position of the deformation amount exceeding the standard when the crease deformation amount of at least part of the positions exceeds the set threshold value.

[0106] The number of coordinate positions with excessive deformation is counted when the coordinate X in the direction perpendicular to the crease direction of the folded area 110 satisfies X0≤X≤X1 and / or the coordinate Y in the direction parallel to the crease direction satisfies Y0≤Y≤Y1. Specifically, this includes: the case where the coordinate X in the direction perpendicular to the crease direction satisfies X0≤X≤X1; the case where the coordinate Y in the direction parallel to the crease direction satisfies Y0≤Y≤Y1; and the case where the coordinate X in the direction perpendicular to the crease direction satisfies X0≤X≤X1 and the coordinate Y in the direction parallel to the crease direction satisfies Y0≤Y≤Y1.

[0107] If the number of coordinate positions with excessive deformation exceeds the first preset number, the areas where the coordinate positions with excessive deformation are located are repaired respectively; conversely, if the number of coordinate positions with excessive deformation does not exceed the first preset number, the repair is stopped.

[0108] In some embodiments, if the crease deformation at at least some locations exceeds a set threshold, repair is performed at the corresponding locations, including:

[0109] If the deformation of the crease at at least some locations exceeds the set threshold, the coordinates of the deformation exceeding the threshold are recorded. If the number of consecutively arranged coordinates of the deformation exceeding the threshold in a coordinate system consisting of the X-axis perpendicular to the crease direction and the Y-axis parallel to the crease direction exceeds the second preset number, the area where the coordinates of the deformation exceeding the threshold are located is repaired to perform a repair mode.

[0110] In some embodiments, the electronic device may include a repair component comprising a plurality of circuits arranged alternately in a direction parallel to and perpendicular to the crease to form a plurality of staggered points 330 within the folded area 110.

[0111] The repair of the corresponding locations includes: repairing at least a portion of the multiple intersection points 330.

[0112] Specifically, multiple interlacing points 330 are configured to correspond one-to-one with multiple pixels, so that the repair component can repair the positions corresponding to multiple pixels separately. Based on this configuration, the repair component can repair the positions corresponding to multiple pixels within the folded area 110 separately through the multiple interlacing points 330, thereby improving the positional accuracy of the repaired positions and increasing the repair efficiency.

[0113] In some embodiments, the repairing assembly can be a heating assembly 300, which includes a plurality of circuits, the plurality of circuits can include a plurality of heating circuits 310 and a plurality of gate circuits 320, wherein the plurality of heating circuits 310 are arranged along one of a direction perpendicular to the crease direction and a direction parallel to the crease direction, and each heating circuit 310 extends along the other of the direction perpendicular to the crease direction and the direction parallel to the crease direction; the plurality of gate circuits 320 are arranged along the other of the direction perpendicular to the crease direction and the direction parallel to the crease direction, and each gate circuit 320 extends along one of the direction perpendicular to the crease direction and the direction parallel to the crease direction.

[0114] Based on the above settings, a longitudinal and transverse staggered circuit can be formed by the plurality of heating circuits 310 and the plurality of gate circuits 320, and the plurality of gate circuits 320 respectively play a control role, and the plurality of heating circuits 310 respectively play a heating role, so as to heat the positions corresponding to the plurality of staggered points 330 by the heating assembly 300.

[0115] In the embodiments of the present application, heating at least part of the plurality of staggered points 330 includes: determining the heating circuit 310 to which a voltage needs to be applied according to the X coordinate of at least part of the staggered points 330 in the direction perpendicular to the crease direction; determining at least one of the heating voltage and the heating duration of the heating circuit 310 according to the crease deformation amount of at least part of the staggered points 330; and determining the gate circuit 320 to which a high level needs to be applied according to the Y coordinate of at least part of the staggered points 330 in the direction parallel to the crease direction.

[0116] Specifically, the coordinate Y value is used to determine which gate circuit 320 needs to apply a high level, the X value is used to determine which heating circuit 310 needs to apply a voltage, and the deformation amount L is used to determine the high and low of the voltage (i.e., the heating voltage) applied to the heating circuit 310 and / or the duration of the applied voltage (i.e., the heating duration). The greater the deformation amount L, the higher the voltage applied to the heating circuit 310 and / or the longer the duration of the applied voltage, so that the position with a greater crease deformation amount can obtain more heat, thereby obtaining better repair.

[0117] The heat generated can be calculated according to Q=T*U 2 In order to generate different heat at different positions, the voltage value of the applied voltage can be fixed, and different conduction durations can be applied; of course, the conduction duration can also be uniform, and the voltage value of the applied voltage at different positions can be different.

[0118] In some embodiments, the repairing component can be the heating component 300, and the repairing method further includes: detecting an external environment temperature of the electronic device; and in a case where the deformation amount of the crease at the at least partial position exceeds a set threshold, heating the corresponding position to repair the crease at the corresponding position, including: adjusting at least one of the heating voltage and the heating time according to the external environment temperature.

[0119] In some embodiments, the temperature detection element can be used to detect the external environment temperature, and at least one of the heating voltage (i.e., the applied voltage) and the heating time (i.e., the power-on time) of the heating component 300 can be changed according to the external environment temperature detected by the temperature detection element. Based on this, the folding screen assembly can still achieve a relatively stable heating repair effect at different external environment temperatures.

[0120] Specifically, at least one of the voltage amplitude applied to the heating circuit 310 and the heating time is adjusted according to the external environment temperature. For example, the lower the external environment temperature, the higher the voltage amplitude applied to the heating circuit 310 and the longer the heating time; on the contrary, the higher the external environment temperature, the lower the voltage amplitude applied to the heating circuit 310 and the shorter the heating time. Based on this, it can be ensured that good heating repair effects can be achieved at different external environment temperatures.

[0121] In some embodiments, the repairing method further includes: in a case where the crease at the at least partial position is repaired, controlling the electronic device to perform a pop-up window prompt.

[0122] By prompting the user through the pop-up window, the impact of the repair process on the user can be alleviated.

[0123] In addition, the repairing method further includes: repairing the crease in a case where the electronic device is in a non-use state and / or the folding screen 100 is in an unfolded state.

[0124] Specifically, the repair can be performed when the user does not use the electronic device during a period of time and it is determined that the folding screen 100 is in an unfolded state, so as to reduce the perception of the user.
