Background

The folding screen has a foldable nature and can be used in a variety of orientations, such as a folded orientation and an unfolded orientation. Terminals with folding screens (known as foldable terminals) generally employ both inward and outward folding. Taking an inwardly folded foldable terminal as an example, the foldable terminal comprises an outer screen in addition to a folding screen (inner screen), and in the process of switching from a folding posture to an unfolding posture or from the unfolding posture to the folding posture, the foldable terminal performs opening and closing detection on the folding screen to determine that a display interface is switched between the inner screen and the outer screen. The folding detection is used for detecting whether the folding screen is switched from the folding posture to the unfolding posture or from the unfolding posture to the folding posture.

Currently, foldable terminals can perform open/close detection on a folding screen through a Hall device in combination with a magnet. However, this scheme needs to increase the device, occupies the framework space, and when there is other magnetism devices in the space, can cause the interference to the magnetism of magnet on the collapsible terminal for open and shut and detect inaccurately, and then lead to the screen to show switching to appear unusual.

When the folding mobile phone 200 is currently in the bright screen state, the folding mobile phone 200 is in the full screen display interface of the internal screen 20 (for example, the a display lock screen interface in fig. 2); when the folding mobile phone 200 is currently in the off-screen state, if the folding mobile phone 200 receives the notification message at this time, the inner screen 20 of the folding mobile phone 200 is awakened, and the notification message is displayed on the inner screen 20.

When the folding cellular phone 200 is folded inward along the foldable area, the folding cellular phone 200 assumes a posture as shown by b in fig. 2. It can be seen that folding handset 200 also includes an external screen 21. During the folding process, the folding mobile phone 200 performs opening and closing detection to determine the display area of the folding mobile phone 200, and in this process, the display area is switched between the inner screen 20 and the outer screen 21.

When the folding mobile phone 200 is fully folded in the folded position, as shown at c in fig. 2, the inner screen 20 is folded out of view and not available for displaying an interface. The external screen 21 is a display area, and can be used for displaying an interface. When the folding mobile phone 200 is currently in the bright screen state, the folding mobile phone 200 displays an interface (e.g., c in fig. 2 displays a lock screen interface) on the external screen 21; when the folding mobile phone 200 is currently in the off-screen state, if the folding mobile phone 200 receives the notification message at this time, the external screen 21 of the folding mobile phone 200 is awakened, and the notification message is displayed on the external screen 21.

Fig. 3 is a schematic diagram of another folding mobile phone according to an embodiment of the present application. As shown in a of fig. 3, the folding mobile phone 300 is in an unfolded state, the folding mobile phone 300 includes a folding screen 30, and the folding screen 30 may include a first screen 301 and a second screen 302 after being folded. The folding mobile phone 300 is folded in such a way as to fold outwards (the first screen 301 and the second screen 302 are located on opposite sides of the body of the folding mobile phone 300 after being fully folded).

When the folding mobile phone 300 is folded inwards along the foldable area, the folding mobile phone 300 may take the gesture shown as b in fig. 3, and during the folding process, the folding mobile phone 300 performs opening and closing detection to determine that the display area is the full screen of the folding screen 30 or the first screen 301/the second screen 302. The display area shown by b in fig. 3 is the first screen 301.

When the folding cellular phone 300 is fully folded in the folded position, as shown in c of fig. 3, the display area of the foldable terminal is the first screen 301. Illustratively, when the user lights up the screen or there is message receipt, a lock screen interface or message notification interface is displayed on the first screen 301.

At present, the terminal equipment can execute opening and closing detection on the folding screen through the Hall device and the magnet. However, this scheme needs to increase the device, occupies the framework space, and when there is other magnetism devices in the space, can cause the interference to the magnetism of the magnet on the terminal equipment for open and shut and detect inaccurately, and then lead to the screen to switch unusual.

In view of this, the embodiment of the application provides a display method of a foldable terminal, which performs opening and closing detection on a folding screen based on a capacitance value of a foldable area, and in this way, additional devices, such as a hall device and a magnet, are not required to be added, so that the architecture space of the terminal equipment can be released, which is beneficial to avoiding the problem of abnormal screen display switching caused by magnetic interference.

Fig. 4 is a schematic flowchart of a display method 400 of a foldable terminal according to an embodiment of the present application. The method 400 is applied to a foldable terminal, the foldable terminal comprises a folding screen, the folding screen comprises a touch electrode structure for touch detection, and the touch electrode structure comprises a plurality of capacitor structures arranged in an array. The folding screen includes a foldable area through which the folding screen is folded or unfolded.

The foldable terminal according to the embodiment of the present application may be, for example, a foldable mobile phone 200 shown in fig. 2, or may be, for example, a foldable mobile phone 300 shown in fig. 3. The foldable terminal may have a structure as shown in fig. 1, but embodiments of the present application are not limited thereto.

The method 400 includes S401 and S402, and the specific steps are as follows:

s401, acquiring a first capacitance value corresponding to at least one capacitance structure in the foldable area.

It should be appreciated that each of the at least one capacitive structure corresponds to a first capacitance value. The first capacitance value corresponding to the at least one capacitance structure may be understood as a first capacitance value corresponding to each capacitance structure in the at least one capacitance structure, the number of the first capacitance values is at least one, and the at least one capacitance structure corresponds to the at least one first capacitance value one by one.

The folding screen of the embodiment of the application comprises a touch screen (TP), and the touch screen can be also called a touch screen or a touch panel, and is an induction type liquid crystal display device capable of receiving input signals such as a contact. The touch screen is an interactive input device, and a user can control the operation of the computer by touching a certain position of the touch screen with a finger or a light pen, and the touch screen has the characteristics of simplicity in operation and flexibility in use.

Illustratively, the touch screen may be a capacitive touch screen, which includes a touch chip including a touch electrode structure for touch detection. The touch electrode structure comprises a plurality of first electrodes (which can be called as transverse electrodes or driving electrodes) which are transversely arranged at intervals and a plurality of second electrodes (which can be called as longitudinal electrodes or sensing electrodes) which are vertically arranged at intervals, the first electrodes and the second electrodes are intersected with each other to form a capacitance structure, and the capacitance structure comprises the positions of intersection points of the first electrodes and the second electrodes.

Most of the current touch chips support a self-capacitance mode and a mutual capacitance mode. The self-capacitance mode is to make a transverse electrode array and a longitudinal electrode array with Indium Tin Oxide (ITO) on the surface of glass, and respectively form a capacitance with ground, and the capacitance is usually a self-capacitance, namely a capacitance of the electrode to the ground, but the self-capacitance cannot achieve real multi-finger touch. The mutual capacitance mode is to make the transverse electrode and the longitudinal electrode on the glass surface by ITO, and the difference between the mutual capacitance mode and the self capacitance mode is that the two groups of electrodes form a capacitance at the crossing place of the two groups of electrodes, namely the two groups of electrodes respectively form two stages of capacitance. When the mobile phone touches the capacitive touch screen, the coupling between the two electrodes near the touch point is affected, so that the capacitance between the two electrodes is equivalently changed.

It should be understood that the first capacitance value and the second capacitance value of the embodiments of the present application refer to the mutual capacitance magnitude. The mutual capacitance will be described as an example.

Taking an example that the touch chip is provided with X transverse electrodes and Y longitudinal electrodes, the area of the touch screen covered by the X transverse electrodes, the Y transverse electrodes and the Y longitudinal electrodes is the touch area (TP area) of the folding screen. When the mutual capacitance is detected, X transverse electrodes send out excitation signals in sequence, Y longitudinal electrodes receive signals at the same time, and therefore capacitance values of all intersection points of the X transverse electrodes and the Y longitudinal electrodes, namely capacitance values of a two-dimensional plane of the whole TP area, can be obtained. The coordinates of each touch point can be calculated according to the two-dimensional capacitance variation data of the capacitive touch screen. Therefore, even if a plurality of touch points exist on the capacitive touch screen, the real coordinates of each touch point can be calculated.

The transverse electrode and the longitudinal electrode may be respectively disposed on two layers of the base plates, with a distance d between the two layers of the base plates. It will be appreciated that the magnitude of the capacitance value is inversely proportional to the distance d between the two layers of the substrate. In the process of switching the folding screen from the folding posture to the unfolding posture, the deformation of the semi-solid laminating adhesive on the screen causes the distance d between the two layers of bottom plates of the foldable area to be gradually reduced, so that the capacitance value of the foldable area can be gradually increased. In contrast, in the process of switching the folding screen from the unfolding posture to the folding posture, the distance d between the two layers of bottom plates of the foldable area is gradually increased due to the deformation of the semi-solid laminating adhesive on the screen, so that the capacitance value of the foldable area is gradually reduced. Based on this principle, the foldable terminal can detect the switching of the posture of the folding screen, that is, whether the folding screen is switched from the folded posture to the unfolded posture or from the unfolded posture to the folded posture.

The image shapes of the transverse electrodes and the longitudinal electrodes can be varied, such as bars, diamonds, triangles. Fig. 5 is a schematic diagram of a touch electrode structure, taking a bar shape as an example.

Illustratively, the size of the folding screen of the foldable terminal shown in fig. 5 is 152mm×132mm, the touch electrode structure of the folding screen includes 38 horizontal electrodes having a bar shape in the shape of an image and arranged at intervals in the horizontal direction and 33 vertical electrodes having a bar shape in the shape of an image and arranged at intervals in the vertical direction (longitudinal direction), the 38 horizontal electrodes and the 33 vertical electrodes intersect each other to form 38×33 capacitance structures, each capacitance structure includes the position of the intersection point of one horizontal electrode and one vertical electrode, and the position of each intersection point corresponds to one first capacitance value, that is, each capacitance structure corresponds to one first capacitance value. According to the size of the folding screen, the number of transverse electrodes and the number of longitudinal electrodes, the distance between two adjacent transverse electrodes is 4mm, and the distance between two adjacent longitudinal electrodes is 4mm.

The foldable terminal may select, as the target area, an area including the position of the intersection of the transverse electrode and the longitudinal electrode of column 17 (intermediate number of columns 1 to 33) in any combination in the foldable area, and acquire the first capacitance value corresponding to the position of at least one intersection (i.e., at least one capacitance structure) in the target area.

Illustratively, as shown by a in fig. 5, the foldable terminal selects a region including the position of the intersection of the transverse electrodes of the 1 st to 38 th rows and the 17 th column longitudinal electrode as a target region 01. The target area 01 includes 38 intersection points of 38 transverse electrodes and 1 longitudinal electrode, each intersection point corresponding to a capacitance value, so that the foldable terminal can acquire 38 first capacitance values in the target area 01.

Illustratively, as shown in b of fig. 5, the foldable terminal selects a region including the position of the intersection of the transverse electrodes of the 1 st to 19 th rows and the 17 th column longitudinal electrode as the target region 02. The target area 02 includes 19 intersection positions of 19 transverse electrodes and 1 longitudinal electrode, each intersection position corresponding to one capacitance value, so that the foldable terminal can acquire 19 first capacitance values in the target area 02.

Illustratively, as shown by c in fig. 5, the foldable terminal selects, as the target region 03, the region at the position of the intersection of the 1 st to 2 nd row transverse electrodes and the 17 th column longitudinal electrode, and the region at the position of the intersection of the 37 th to 38 th row transverse electrodes and the 17 th column longitudinal electrode. The target area 03 includes positions of 4 intersections of the 4 transverse electrodes and one longitudinal electrode, each of which corresponds to one capacitance value, so that the foldable terminal can acquire 4 first capacitance values in the target area 03.

The division of the touch screen is determined by comprehensively considering the screen size, the screen processing technology and the number of electrodes of the adopted touch chip. When the size of the folding screen of the foldable terminal is 152mm×132mm, the touch chip adopted by the touch screen can also contain 76 transverse line electrodes and 65 longitudinal electrodes, and the 76 transverse electrodes and the 65 longitudinal electrodes are intersected with each other to form 76×65 capacitance structures.

Similar to the above description with respect to fig. 5, the foldable terminal may exemplarily determine, as the target area, an area including the position of the intersection of the transverse electrode and the longitudinal electrode of the intermediate column (i.e., 33 th column, 33 is an intermediate number of 1 to 65) in any combination in the foldable area.

Still or because the 76 cross-line drive circuits and 65 longitudinal electrodes divide the touch screen more finely, more columns of longitudinal electrodes may be included in the foldable area of the folding screen, including, for example, the 32 th column, the 33 th column, and the 34 th column of longitudinal electrodes. The foldable terminal can thus also determine, as the target area, an area containing the positions of intersections of any combination of the transverse electrodes with the 32 th, 33 th, and 34 th column longitudinal electrodes in the foldable area. The selection of the target area is not limited in the embodiment of the application, but the target area needs to be limited in the foldable area.

In the process of actually determining the target area, the foldable terminal may acquire the change amount of the capacitance values of the positions of the intersections of all the driving electrodes and the sensing electrodes in the foldable area in the process of changing the folding screen from the folding posture to the unfolding posture (or in the process of changing the folding screen from the unfolding posture to the folding posture), and determine the change interval of the capacitance values of the foldable terminal, for example [ C, D ], where C is (or is approximately) the capacitance value corresponding to the position of the intersection of each transverse electrode and each longitudinal electrode in the folding posture, and D is (or is approximately) the capacitance value corresponding to the position of the intersection of each transverse electrode and each longitudinal electrode in the unfolding posture.

The foldable terminal can select an area formed by the positions of the intersections of the first M transverse line electrodes and the longitudinal electrodes with the largest capacitance value variation in the foldable area as a target area, wherein M is more than or equal to 2. The larger the variation of the capacitance value is, the larger the variation interval [ C, D ] of the capacitance value is, the more sensitive the position of the intersection point of the transverse line electrode and the longitudinal electrode with large variation is to the variation of the gesture of the folding screen, which is beneficial to setting more proper threshold value in the variation interval [ C, D ] for screen display switching, and improving the stability and accuracy of screen display switching.

S402, determining a display area of the foldable terminal according to the first capacitance value.

It should be understood that the foldable terminal selects a first capacitance value corresponding to at least one capacitance structure in the foldable area, and the first capacitance value is changed in real time during the folding or unfolding process of the folding screen, so that the foldable terminal can perform opening and closing detection on the folding screen according to the changed capacitance value, thereby determining the display area of the terminal device.

According to the technical scheme, the foldable terminal does not need to be provided with additional devices (such as a magnet and a Hall assembly), so that the occupation of the space of the foldable terminal is reduced. As the posture of the folding screen changes, the first capacitance value corresponding to at least one capacitance structure of the transverse electrode and the longitudinal electrode in the foldable area also changes. Therefore, the foldable terminal can realize the opening and closing detection of the folding screen according to the first capacitance value which changes in real time, so that the display area of the foldable terminal is determined, the mode is simple to realize, the problem that the switching display area is abnormal due to inaccurate opening and closing detection is avoided, and the use experience of a user is improved.

As an alternative embodiment, prior to S401, the method 400 further includes: when a screen of the terminal equipment is lightened, acquiring a second capacitance value corresponding to the at least one capacitance structure in the foldable area; and determining whether the second capacitance value corresponding to each capacitor structure in the at least one capacitor structure is abnormal. S401 includes: and under the condition that the second capacitance value corresponding to each capacitance structure is not abnormal, acquiring the first capacitance value.

In an embodiment of the present application, the at least one capacitance structure includes the positions of the intersections of the transverse electrodes and the longitudinal electrodes included in the target area described above, and each intersection corresponds to one second capacitance value, so each capacitance structure corresponds to one second capacitance value.

After the foldable terminal determines the target area, when the foldable terminal is on (including power on) each time, the foldable terminal firstly obtains the second capacitance value corresponding to the at least one capacitance structure of the target area, and detects whether the second capacitance value corresponding to each capacitance structure is abnormal or not. Under the condition that the second capacitance value corresponding to any one capacitor structure is abnormal, the foldable terminal prompts a user to carry out screen maintenance, and the folding screen is opened and closed in other modes. Under the condition that the second capacitance value corresponding to each capacitance structure is not abnormal, the foldable terminal executes the display method 400 of the foldable terminal, so that the success rate of opening and closing detection through the first capacitance value is improved, and the accuracy of screen display switching is improved.

When detecting whether the second capacitance value corresponding to each capacitance structure is abnormal or not, the foldable terminal judges whether the second capacitance value corresponding to each capacitance structure is within a preset threshold range [ A, B ], and if the second capacitance value is within the preset threshold range [ A, B ], the foldable terminal determines that the second capacitance value corresponding to each capacitance structure is not abnormal. If the second capacitance value corresponding to any one of the capacitance structures is not within the preset threshold range [ A, B ], the foldable terminal determines that the screen is abnormal. Wherein A, B can be determined from large data analysis of capacitance values for a large number of normal screens.

A specific implementation of determining the display area of the foldable terminal based on the first capacitance value is described below.

One possible scenario one: the folding mode of the folding screen is inward folding, the folding screen is an inner screen of the foldable terminal, the foldable terminal further comprises an outer screen, and the inner screen and the outer screen are positioned on two opposite sides of the main body of the foldable terminal. When the gesture of folding screen changes, collapsible terminal switches the display interface between interior screen and outer screen, and the display area that can fold the terminal is interior screen or outer screen.

One possible scenario two: the folding mode of the folding screen is outward folding, and when the folding mode is outward folding, the foldable terminal can be not provided with the outer screen. When the gesture of the folding screen changes, the foldable terminal switches the display interface between the full screen of the folding screen and a part of the screen (for example, the first screen 301 or the second screen 302 in fig. 3), that is, the display area of the foldable terminal is the full screen of the folding screen or the part of the screen of the folding screen.

In the following, a specific implementation of determining, by the foldable terminal, a display area of the foldable terminal according to the first capacitance value will be described by taking a first scenario as an example.

Assume one: the current posture of the folding screen is a folding posture, and a user desires to switch the folding screen from the folding posture to the unfolding posture. The external screen of the foldable terminal is used for displaying an interface when the folding screen is in the folded posture.

FIG. 6 is a graph showing a relationship between capacitance and on-screen policy according to an embodiment of the present application. Referring to fig. 6, the abscissa represents capacitance values, and the ordinate represents an on-screen strategy, wherein an output of "0" represents an external screen display interface, and an output of "1" represents an internal screen (full screen of a folded screen) display interface. In the folded position, the first capacitance value corresponding to each capacitive structure in the target area is C, or approximately C. During the process that the folding screen is unfolded, the first capacitance value corresponding to each capacitance structure in the target area is gradually increased from C to D. In the unfolded posture, the first capacitance value corresponding to each capacitance structure in the target area is D or is approximately D.

The foldable terminal can detect opening and closing of the folding screen according to the change of the first capacitance value corresponding to each capacitance structure in the target area.

In one possible implementation, the foldable terminal may determine that the folding screen is switching from the folded position to the unfolded position when detecting that the first capacitance value corresponding to each capacitive structure in the target area changes from small to large.

In another possible implementation, the foldable terminal further includes an acceleration sensor, and the foldable terminal may detect a change in an angle of the folding screen according to the acceleration sensor. When the included angle of the folding screen is detected to be changed from small to large, the foldable terminal can determine that the folding screen is being switched from the folding posture to the unfolding posture.

And under the condition that the folding screen is switched from the folding posture to the unfolding posture, if the first capacitance value corresponding to any one of the at least one capacitance structure is smaller than a first threshold value, the foldable terminal determines that the display area is the outer screen, namely, the interface is continuously displayed by the outer screen.

Under the condition that the folding screen is switched from the folding posture to the unfolding posture, if the first capacitance value corresponding to each capacitance structure in the at least one capacitance structure is larger than or equal to a first threshold value, the foldable terminal determines that the display area is an inner screen (full screen of the folding screen), namely, the outer screen display interface is switched to the full screen display interface of the folding screen.

Suppose two: the current posture of the folding screen is an unfolding posture, and a user desires to switch the folding screen from the unfolding posture to the folding posture. When the folding screen is in the unfolded posture, the inner screen of the foldable terminal (full screen of the folding screen) is used for displaying the interface.

FIG. 7 is a graph showing a relationship between capacitance and on-screen policy according to another embodiment of the present application. Referring to fig. 7, the abscissa represents capacitance values, and the ordinate represents an on-screen strategy, wherein an output of "0" represents an external screen display interface, and an output of "1" represents an internal screen (full screen of a folded screen) display interface. In the unfolded posture, the first capacitance value corresponding to each capacitance structure in the target area is D, or is approximately D. The first capacitance value corresponding to each capacitance structure in the target area gradually decreases from D to C during the process that the folding screen is folded. In the folded position, the first capacitance value corresponding to each capacitive structure in the target area is C, or approximately C.

Similar to the description above for hypothesis one, in one possible implementation, the foldable terminal may determine that the folding screen is being switched from the unfolded posture to the folded posture when detecting that the first capacitance value corresponding to each capacitive structure in the target area changes from large to small.

In another possible implementation, the foldable terminal may determine that the foldable screen is being switched from the unfolded posture to the folded posture when the foldable terminal detects that the angle of the foldable screen is changed from large to small according to the acceleration sensor.

Under the condition that the folding screen is switched from the unfolding posture to the folding posture, if the first capacitance value corresponding to any one of the at least one capacitance structure is larger than the second threshold value, the foldable terminal determines that the display area is an inner screen, namely, the full screen display interface of the folding screen is continued, and the outer screen is still not used for displaying the interface.

Under the condition that the folding screen is switched from the unfolding posture to the folding posture, if the first capacitance value corresponding to each capacitance structure in the at least one capacitance structure is smaller than or equal to the second threshold value, the foldable terminal determines that the display area is an outer screen, namely, the full screen display interface of the folding screen is switched to the outer screen display interface.

In one possible implementation, the first threshold value is equal to the second threshold value. Illustratively, the first and second thresholds may be (C+D)/2.

In another possible implementation, the first threshold is greater than the second threshold. Illustratively, the first and second thresholds are symmetrically valued with (C+D)/2 as a point of symmetry. Taking c=10 and d=30 as an example, (c+d)/2=20, the first threshold may be 20+5=25, and the second threshold may be 20-5=15; or the first threshold may be 20+3=23 and the second threshold may be 20-3=17. In general, (c+d)/2 corresponds to an intermediate state (for example, an included angle of the folding screen is 90 degrees) in which the folding screen is folded or unfolded, and in the intermediate state, the folding screen may shake, and the shaking of the folding screen may cause a change in a capacitance value of the target area, so that a problem of frequent switching of the screen display occurs. In the embodiment of the application, if the first threshold and the second threshold are symmetrically valued by taking (C+D)/2 as the symmetrical points, the posture of the folding screen corresponding to the valued by taking (C+D)/2 as the symmetrical points is stable, and a space which can allow the screen of the folding screen to shake is reserved between the first threshold and the second threshold, so that the problem of frequent switching of the display area caused by screen shake is reduced, and the use experience of a user is improved.

In the following, a specific implementation of determining, by the foldable terminal, a display area of the foldable terminal according to the first capacitance value is described taking a second scenario as an example.

Assume three: the current posture of the folding screen is a folding posture, and a user desires to switch the folding screen from the folding posture to the unfolding posture. When the folding screen is in the folded position, either the first screen or the second screen of the folding screen is used to display an interface.

Similar to the assumption one in the scene one, the foldable terminal can perform opening and closing detection on the folding screen according to the change of the first capacitance value corresponding to each capacitance structure in the target area. The detection method is similar to that described in assumption one, and will not be repeated here.

Under the condition that the folding screen is switched from the folding posture to the unfolding posture, if the first capacitance value corresponding to each capacitance structure in the at least one capacitance structure is larger than or equal to a third threshold value, the foldable terminal determines that the display area is the full screen of the folding screen, namely, the display interface of the first screen or the second screen is switched to the full screen display interface of the folding screen.

And under the condition that the folding screen is switched from the folding posture to the unfolding posture, if the first capacitance value corresponding to any one capacitance structure is smaller than a third threshold value, the foldable terminal determines that the display area is the first screen, namely, the first screen is continuously used for displaying the interface.

Suppose four: the current posture of the folding screen is an unfolding posture, and a user desires to switch the folding screen from the unfolding posture to the folding posture. When the folding screen is in the unfolding state, the folding screen of the foldable terminal is used for displaying the interface in a full screen mode.

Similar to the second assumption in the first scenario, the foldable terminal may perform the opening/closing detection on the folding screen according to the change of the first capacitance value corresponding to each capacitance structure in the target area. The detection method is similar to that described in the assumption two, and is not repeated here.

Under the condition that the folding screen is switched from the folding posture to the unfolding posture, if the first capacitance value corresponding to any one of the at least one capacitance structure is larger than the fourth threshold value, the foldable terminal determines that the display area is the full screen of the folding screen, namely, the full screen display interface of the folding screen is continuously displayed.

Under the condition that the folding screen is switched from the folding posture to the unfolding posture, if the first capacitance value corresponding to each capacitance structure in the at least one capacitance structure is smaller than or equal to a fourth threshold value, the foldable terminal determines that the display area is the first screen or the second screen, namely, the full-screen display interface of the folding screen is switched to the first screen or the second screen display interface of the folding screen.

Similar to the magnitude relationship of the first and second thresholds described in scenario one, the third threshold may be greater than or equal to the fourth threshold.

Illustratively, the third and fourth thresholds are symmetrically valued with (C+D)/2 as a point of symmetry. Taking c=10, d=30 as an example, (c+d)/2=20, the third threshold may be 20+5=25, and the fourth threshold may be 20-5=15; or the third threshold may be 20+3=23 and the fourth threshold may be 20-3=17. In general, (c+d)/2 corresponds to an intermediate state (for example, an included angle of the folding screen is 90 degrees) in which the folding screen is folded or unfolded, and in the intermediate state, the folding screen may shake, and the shaking of the folding screen may cause a change in a capacitance value of the target area, so that a problem of frequent switching of the screen display occurs. In the embodiment of the application, if the third threshold and the fourth threshold are symmetrically valued by taking (C+D)/2 as the symmetrical points, the posture of the folding screen corresponding to the valued by taking (C+D)/2 as the symmetrical points is more stable, and a space for allowing the screen of the folding screen to shake is reserved between the third threshold and the fourth threshold, so that the problem of frequent switching of the display area caused by screen shake is favorably reduced, and the use experience of a user is improved.

In the embodiment of the application, the foldable terminal obtains the first capacitance value corresponding to the at least one capacitance structure through the touch chip, and the touch chip can send the obtained first capacitance value corresponding to the at least one capacitance structure to the processor after analog-to-digital conversion so as to execute the operation of determining the display area of the foldable terminal. That is, the first capacitance value corresponding to each capacitance value compared with the threshold value in the embodiment of the present application is a capacitance value after having been digitized.

In the above, it is described that the foldable terminal performs the method 400 provided by the present application when the second capacitance value corresponding to each of the at least one capacitance structure of the target area acquired by the foldable terminal is not abnormal. However, under the condition that the second capacitance value corresponding to any one of the at least one capacitance structure is abnormal, if the first capacitance value corresponding to the at least one capacitance structure of the target area is acquired again, the folding screen is subjected to folding detection, so that the folding monitoring can be inaccurate, and the screen display switching is abnormal.

Based on the above, the embodiment of the application provides another display method of foldable equipment, which determines the display area of the foldable terminal based on the included angle of the folding screen acquired by the foldable terminal in real time.

Illustratively, the two sides of the foldable device each have an A+G sensor (accelerometer-sensor) that can calculate the angle of the folded screen by rotation of the rotation point in two dimensions.

For example, a point on the screen of the foldable device has a coordinate P (x _p,y_p), and after a counterclockwise rotation angle θ, the point has a coordinate Q (x _q,y_q), and the coordinate P and the coordinate Q have the following relationship:

Since P (x _p,y_p) and Q (x _q,y_q) are known, the rotation angle θ can be calculated by the above equation, and the included angle of the folding screen can be obtained according to the rotation angle θ.

The included angle of the folding screen changes in real time in the folding or unfolding process, and is larger and larger in the process of switching from the folding posture to the unfolding posture, so that when the foldable equipment detects that the included angle of the folding screen is larger and larger, the folding screen can be determined to be switched from the folding posture to the unfolding posture. Accordingly, the included angle of the folding screen is smaller and smaller in the process of switching from the unfolding posture to the folding posture, so that when the foldable device detects that the included angle of the folding screen is smaller and smaller, it can be determined that the folding screen is being switched from the unfolding posture to the folding posture.

In a similar manner to the above-described manner of determining the display area of the foldable terminal according to the first capacitance value corresponding to the at least one capacitance structure, the foldable terminal may determine the display area of the foldable terminal according to the magnitude of the included angle of the foldable screen in a case where the switching direction of the posture of the foldable screen is determined (switching from the folded posture to the unfolded posture, or switching from the unfolded posture to the folded posture).

For a folding screen with an inward folding mode, as shown in fig. 8, when the folding screen is in a folded posture, the included angle of the folding screen is 0. The output of "0" indicates that an external screen display interface is adopted, and the output of "1" indicates that an internal screen (full screen of a folding screen) display interface is adopted.

Under the condition that the foldable terminal determines that the folding screen is switched from the folding posture to the unfolding posture, if the included angle of the folding screen is detected to be smaller than a first preset angle, the display area of the foldable terminal is determined to be the outer screen. If the foldable terminal detects that the included angle of the folding screen is larger than or equal to the first preset angle, the display area of the foldable terminal is determined to be an inner screen (full screen of the folding screen).

For a folding screen folded inwards, as shown in fig. 9, when the folding screen is in an unfolded state, the included angle of the folding screen is pi (180 °).
