[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0023] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0024] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0025] With the development of screen technology, more and more manufacturers are launching foldable screen electronic devices. These foldable screen electronic devices can be folded once when operated by the user with one hand, and can be unfolded into two or three folds when placed on the table, giving users a wider and more shocking screen visual experience.

[0026] Usually, folding screens use capacitive touch screens. Unlike resistive touch screens, capacitive touch screens do not rely on finger pressure to create and change voltage values ​​to detect coordinates. Capacitive touch screens work through any object that holds an electric charge, including human skin. Capacitive touch screens are made of materials such as alloys or indium tin oxides, and the charge is stored in a very fine micro-electrostatic network. When a finger clicks the screen, a small amount of current is absorbed from the contact point, causing a voltage drop in the corner electrode, and the purpose of touch is achieved by inducing the weak current of the human body.

[0027] In addition, the capacitive touch screen is mainly composed of a transmitting channel and a receiving channel, wherein the capacitance data collected from the transmitting channel and the receiving channel to the ground is self-capacitance data, and the data collected from the transmitting channel and the receiving channel is mutual capacitance data. Currently, mutual capacitance data is used to determine whether the user's finger is in a pressed, moved, or lifted state. Self-capacitance data is used to determine other auxiliary functions, such as proximity sensing functions.

[0028] It should also be understood that the working principle of the capacitive touch screen is to trigger a scanning signal of a certain frequency at a fixed time, detect whether an object is pressed on the surface of the touch screen of the terminal device, and calculate the coordinates based on the capacitive signal for reporting. Specifically, the touch screen recognizes the coordinates of the object by calculating the current original capacitance value and the difference between it and the reference capacitance value. By calculating the area of ​​the capacitance difference, the peak value of the area is found to determine whether it is within a certain preset reporting threshold, thereby sending the reporting point coordinates from the terminal system. Among them, the capacitive sensing function of the touch screen uses the capacitive sensing principle of the touch screen to determine whether the object contacts the touch screen and then reports the state of the object, which mainly refers to the state of objects such as fingers and contact pens, which is mainly divided into pressing and lifting and movement after pressing, etc. The reported data includes: coordinate data, and event status.

[0029] During the application of foldable screen electronic devices, it is usually necessary to control the display state, operation method, etc. of the foldable screen electronic device according to its folding angle to match the user's usage habits. This requires real-time detection of the folding angle of the foldable screen.

[0030] In the current related technology, taking the folding screen including the first screen and the second screen as an example, the main screen of the folding screen uses a touch screen as a sensor to collect capacitance data changes, so as to calculate the folding angle of the first screen and the second screen according to the capacitance change, such as Figure 1 Shown is an exemplary structural diagram of the first screen, the second screen, and the folding angle.

[0031] That is to say, most current solutions for calculating the folding angle of folding screens use the capacitance data collected when the screen is 180 degrees as the baseline data, and then collect the capacitance data at different angles as the original data, and calculate the difference between the baseline data and the original data, and then filter and calculate the folding angle data. Since the use of sensor solutions to calculate the folding angle will increase costs, the use of touch screens as angle detection solutions is being studied.

[0032] However, the solution of using the touch screen to collect data to calculate the folding angle of the folding screen is easily affected by the external environment, resulting in the problem of inaccurate calculation of the folding angle using capacitance. Therefore, how to improve the accuracy of the folding angle calculation of the folding screen is an urgent problem to be solved.

[0033] In view of this, an embodiment of the present application provides a method for detecting the folding angle of a folding screen, which is applied to an electronic device with a folding screen, and the method specifically includes: obtaining the target temperature and target self-capacitance data of the electronic device at the current moment, and the target self-capacitance data is used to indicate the capacitance data of different channels in the folding screen to the ground; and then determining the target folding angle of the folding screen at the current moment according to the target temperature and the target self-capacitance data. In the method for detecting the folding angle of the folding screen, the electronic device combines the target temperature and the target self-capacitance data to determine the target folding angle of the folding screen at the current moment, which can improve the accuracy of the folding angle calculation when the temperature of the electronic device changes.

[0036] The processor 210 is the control center of the electronic device, and uses various interfaces and lines to connect various parts of the entire electronic device.

[0046] In order to make the purpose and technical solution of this application clearer and more intuitive, the following will be combined with the accompanying drawings and embodiments to describe in detail the detection method, device, equipment, and storage medium of the folding angle of the folding screen provided in the embodiments of this application. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0047] Please refer to Figure 3 , is a schematic diagram of the implementation flow of a method for detecting the folding angle of a folding screen provided by an embodiment of the present application. The method can be applied to Figure 1 The foldable screen electronic device or Figure 2 The electronic equipment shown, such as Figure 3 As shown, the method may include the following steps 301 and 302:

[0048] Step 301, obtaining the target temperature and target self-capacitance data of the electronic device at the current moment, where the target self-capacitance data is used to indicate the capacitance data of different channels in the folding screen to the ground.

[0049] It should be understood that the target temperature of the electronic device at the current moment may be obtained by adding a temperature sensor in the electronic device, or may be obtained by using a temperature sensor built into the electronic device, and this application does not specifically limit this.

[0050] It should also be understood that the capacitance data of different channels in the folding screen to the ground is called self-capacitance data. For example, a capacitive touch screen is mainly composed of a transmitting channel and a receiving channel, wherein the capacitance data collected from the transmitting channel and the receiving channel to the ground in some embodiments is self-capacitance data.

[0051] In some embodiments, the electronic device obtains the capacitance data of different channels in the folding screen to the ground at the current moment as the target self-capacitance data.

[0052] Step 302, determining the target folding angle of the folding screen at the current moment according to the target temperature and the target self-capacitance data.

[0053] In some embodiments, the electronic device can determine the target folding angle of the folding screen at the current moment based on the target temperature and the target self-capacitance data, combined with the mapping relationship between the temperature, self-capacitance data and the folding angle of the folding screen preset in the electronic device; it can also determine the target folding angle of the folding screen at the current moment based on the target self-capacitance data, combined with the mapping relationship between the self-capacitance data and the folding angle, and the mapping relationship between the temperature and the compensation angle; or it can be other ways, which are not limited to the present application.

[0054] It should be noted that the folding angle of the folding screen mentioned in the embodiment of the present application is based on Figure 1 The folding angle between the first screen and the second screen shown in the figure is used as an example for explanation. Of course, it can also be a folding angle in other directions, and this application does not limit this.

[0055] In this embodiment, the electronic device with a folding screen first obtains the target temperature and target self-capacitance data at the current moment, and then determines the target folding angle of the folding screen at the current moment based on the target temperature and target self-capacitance data. In this method, the electronic device combines the target temperature and target self-capacitance data to determine the target folding angle of the folding screen at the current moment, which can improve the accuracy of the folding angle calculation when the temperature of the electronic device changes.

[0056] Based on the above embodiments, Figure 4 A schematic diagram of the implementation flow of a method for detecting the folding angle of a folding screen provided in another embodiment of the present application is shown in FIG. Figure 4 As shown, the method may include the following steps 401 to 403:

[0057] Step 401, obtaining the target temperature and target self-capacitance data of the electronic device at the current moment, where the target self-capacitance data is used to indicate the capacitance data of different channels in the folding screen to the ground.

[0058] It should be understood that the target temperature of the electronic device at the current moment may be obtained by adding a temperature sensor in the electronic device, or may be obtained by using a temperature sensor built into the electronic device, and this application does not specifically limit this.

[0059] It should also be understood that, taking the folding screen as a capacitive touch screen as an example, the capacitive sensing of a capacitive touch screen is generally divided into two types, one is single-ended sensing, also known as self-capacitance, where both the horizontal and vertical electrodes are driven by a single-ended sensing method, i.e., the driving circuits for a row and a column are the same. The other is mutual capacitance, where one axis is driven by a set of alternating current (AC) signals, and the response passing through the touch screen is sensed by electrodes on other axes, called transverse sensing, because the electric field is transmitted from one electrode group (such as a row) to another electrode group (such as a column) in a transverse manner through the dielectric layer of the upper panel.

[0060] Among them, for mutual capacitance, its transmitting end and receiving end are different and cross vertically. Indium tin oxide (ITO) is used to make horizontal electrodes and vertical electrodes. The difference between it and the capacitor is that the place where the two groups of electrodes cross will form a capacitor, that is, the two groups of electrodes constitute the two poles of the capacitor respectively. When the finger touches the capacitive screen, it affects the coupling between the two electrodes near the touch point, thereby changing the capacitance between the two electrodes. When detecting the size of the mutual capacitance, the horizontal electrodes send out excitation signals in turn, and all the vertical electrodes receive the signals at the same time, so that the capacitance value of all the intersection points of the horizontal and vertical electrodes can be obtained, that is, the capacitance size of the entire two-dimensional plane of the touch screen. For self-capacitance, its transmitting end and receiving end are the same. ITO is used to make horizontal and vertical electrode arrays on the glass surface, and they form capacitors with the ground respectively. When the finger touches the capacitive screen, the capacitance of the finger will be superimposed on the capacitance of the screen body, increasing the capacitance of the screen body.

[0061] It should be noted that the embodiments of the present application are mainly described by taking the collection of self-capacitance data of the folding screen, that is, self-capacitance data as an example.

[0062] In some embodiments, the electronic device obtains the capacitance data of different channels in the folding screen to the ground at the current moment as the target self-capacitance data.

[0063] Step 402, searching for a target mapping relationship corresponding to the target temperature from the mapping relationship between the preset temperature, the self-capacitance data, and the folding angle of the folding screen.

[0064] In some embodiments, the mapping relationship between the preset temperature, the self-capacitance data, and the folding angle of the folding screen includes a mapping relationship of a table and a mapping relationship of a function.

[0065] The mapping relationship in the table is used to indicate a one-to-one correspondence between the temperature, the self-capacitance data, and the folding angle of the folding screen. The mapping relationship in the table can be determined by collecting the current folding angle of the folding screen, the corresponding temperature, and the self-capacitance data.

[0066] Optionally, the self-capacitance data at different temperatures can be the average value of the self-capacitance data of multiple channels in the folding screen, or the self-capacitance data of the folding channel of the folding screen, or the difference information between the folding channel of the folding screen and the adjacent channels. This application does not limit this specifically.

[0067] Exemplarily, the current folding angle of the folding screen ranges from 0 degrees to 180 degrees. Taking the temperatures of 25 degrees, 0 degrees and minus 20 degrees as examples, the folding angle and self-capacitance data at different temperatures are collected, and the following table 1 can be obtained:

[0068] Table 1

[0069]

[0070] It should be noted that the error of the folding angle obtained according to the mapping relationship in the table is about 10 degrees.

[0071] It should be understood that the mapping relationship of the function is used to indicate the functional relationship between the folding angle of the folding screen and the self-capacitance data at different temperatures. The functional relationship between the folding angle of the folding screen and the self-capacitance data is obtained by solving the equation based on the folding angle and self-capacitance data collected at different temperatures.

[0072] For example, at different temperatures, the functional relationship between the folding angle of the folding screen and the self-capacitance data may be the following mapping relationship:

[0073] Angle = T1 * func1 (cap);

[0074] Angle = T2*func2(cap).

[0075] Among them, T1 and T2 are different temperature data, func1 and func2 represent different function mapping relationships, cap is the current self-capacitance data, and Angle is the output folding angle of the folding screen.

[0076] In one possible implementation, the electronic device may search for a target mapping relationship corresponding to the target temperature from a mapping relationship in a table among preset temperatures, self-capacitance data, and the folding angle of the folding screen; or search for a target mapping relationship corresponding to the target temperature from a mapping relationship in a function among preset temperatures, self-capacitance data, and the folding angle of the folding screen.

[0077] Step 403, when the target mapping relationship exists, the target folding angle is obtained according to the target self-contained data and the target mapping relationship.

[0078] In some embodiments, when the electronic device determines that a target mapping relationship exists, when the mapping relationship among the preset temperature, self-capacitance data, and the folding angle of the folding screen is a tabular mapping relationship, the electronic device finds the corresponding folding angle in the target mapping relationship according to the target self-capacitance data to obtain the target folding angle; when the mapping relationship among the preset temperature, self-capacitance data, and the folding angle of the folding screen is a functional mapping relationship, the electronic device calculates the target folding angle according to the functional relationship between the target self-capacitance data and the target mapping relationship.

[0079] In a possible implementation, when the target mapping relationship does not exist, the electronic device obtains the target folding angle according to the preset mapping relationship between the self-capacitance data and the folding angle, and the target self-capacitance data. That is to say, the electronic device also presets a default mapping relationship between the self-capacitance data and the folding angle, and when there is no target mapping relationship corresponding to the target temperature in the mapping relationship between the preset temperature, the self-capacitance data, and the folding angle of the folding screen, the target folding angle is obtained based on the preset default mapping relationship between the self-capacitance data and the folding angle, and the target self-capacitance data.

[0080] In this embodiment, the electronic device with a folding screen first obtains the target temperature and target self-capacitance data at the current moment, and then searches for a target mapping relationship corresponding to the target temperature from the mapping relationship between the preset temperature, self-capacitance data, and the folding angle of the folding screen, and then obtains the target folding angle according to the target self-capacitance data and the target mapping relationship when the target mapping relationship exists. In this method, the electronic device is preset with a mapping relationship between the temperature, self-capacitance data, and the folding angle of the folding screen, and the target folding angle of the folding screen at the current moment is determined according to the mapping relationship combined with the target temperature and the target self-capacitance data, which can solve the problem of inaccurate calculation of the folding angle by the folding screen through the self-capacitance data collected by the touch screen when the temperature changes sharply or at low or high temperatures.

[0081] Based on the above embodiments, Figure 5 A schematic diagram of the implementation flow of a method for detecting the folding angle of a folding screen provided in another embodiment of the present application is shown in FIG. Figure 5 As shown, the method may include the following steps 501 to 504:

[0082] Step 501, obtaining the target temperature and target self-capacitance data of the electronic device at the current moment, where the target self-capacitance data is used to indicate the capacitance data of different channels in the folding screen to the ground.

[0083] It should be understood that the target temperature of the electronic device at the current moment may be obtained by adding a temperature sensor in the electronic device, or may be obtained by using a temperature sensor built into the electronic device, and this application does not specifically limit this.

[0084] It should also be understood that the capacitance data of different channels in the folding screen to the ground is called self-capacitance data. For example, a capacitive touch screen is mainly composed of a transmitting channel and a receiving channel, wherein the capacitance data collected from the transmitting channel and the receiving channel to the ground in some embodiments is self-capacitance data.

[0085] In some embodiments, the electronic device obtains the capacitance data of different channels in the folding screen to the ground at the current moment as the target self-capacitance data.

[0086] Step 502, determining a first folding angle according to a preset mapping relationship between self-capacity data and folding angles, and target self-capacity data.

[0087] It should be understood that the mapping relationship between the preset self-capacitance data and the folding angle is obtained based on a plurality of self-capacitance data and corresponding folding angles collected at the same temperature.

[0088] In some embodiments, a mapping relationship between self-capacitance data and folding angle is preset in the electronic device, and the mapping relationship can be obtained by solving an equation. For example, assuming that there is a certain functional relationship between the self-capacitance data and the folding angle, such as a quadratic functional relationship, three sets of self-capacitance data and folding angles can be collected, brought into the quadratic functional relationship to solve the equation, and the functional relationship can be obtained. The mapping relationship can also be a table of self-capacitance data and folding angles collected in real time, and a mapping relationship of the table can be obtained, or other methods can be used, and this application does not limit this.

[0089] In some embodiments, when the mapping relationship between the preset self-capacitance data and the folding angle is a mapping relationship of a table, the electronic device searches the table according to the target self-capacitance data to obtain a first folding angle; when the mapping relationship between the preset self-capacitance data and the folding angle is a mapping relationship of a function, the electronic device calculates according to the target self-capacitance data and the function relationship to obtain the first folding angle.

[0090] Step 503, determining a target compensation angle according to a preset mapping relationship between temperature and compensation angle and a target temperature.

[0091] In some embodiments, at different temperatures, there is angle compensation data for the folding angle of the folding screen, that is, there is a mapping relationship between the temperature and the compensation angle, for example, it can be a mapping relationship in a table, as shown in Table 2 below:

[0092] Table 2

[0093] temperature 25 degrees 0 degrees -20 degrees Compensation Angle 10 degrees 5 degrees 10 degrees

[0094] Of course, other forms of mapping relationships are also possible, and this application does not specifically limit this.

[0095] In a possible implementation, the electronic device searches a preset mapping relationship between temperature and compensation angle according to the target temperature to obtain a corresponding target compensation angle.

[0096] Step 504: determine a target folding angle according to the sum of the first folding angle and the target compensation angle.

[0097] In some embodiments, by querying the mapping relationship between the preset temperature and the compensation angle, if the target compensation angle at the current target temperature exists, the target folding angle is determined according to the sum of the first folding angle and the target compensation angle.

[0098] Exemplarily, the first folding angle is 50 degrees, the target compensation angle is 10 degrees, and the target folding angle is 60 degrees.

[0099] In this embodiment, the electronic device first obtains the target temperature and target self-capacitance data at the current moment, and then determines the first folding angle according to the mapping relationship between the preset self-capacitance data and the folding angle, and the target self-capacitance data, and at the same time determines the target compensation angle according to the mapping relationship between the preset temperature and the compensation angle, and the target temperature, and finally determines the target folding angle according to the sum of the first folding angle and the target compensation angle. In this method, the electronic device performs compensation processing on the folding angle at the corresponding temperature according to the mapping relationship between the temperature and the compensation angle, which can improve the accuracy of the folding angle calculation when the temperature of the electronic device changes.

[0100] Based on the above embodiments, Figure 6 A schematic diagram of the implementation flow of a method for detecting the folding angle of a folding screen provided in another embodiment of the present application is shown in FIG. Figure 6 As shown, the method may include the following steps 601 to 604:

[0101] Step 601, obtaining the target temperature and target self-capacitance data of the electronic device at the current moment, where the target self-capacitance data is used to indicate the capacitance data of different channels in the folding screen to the ground.

[0102] It should be understood that the target temperature of the electronic device at the current moment may be obtained by adding a temperature sensor in the electronic device, or may be obtained by using a temperature sensor built into the electronic device, and this application does not specifically limit this.

[0103] It should also be understood that the capacitance data of different channels in the folding screen to the ground is called self-capacitance data. For example, a capacitive touch screen is mainly composed of a transmitting channel and a receiving channel, wherein the capacitance data collected from the transmitting channel and the receiving channel to the ground in some embodiments is self-capacitance data.

[0104] In some embodiments, the electronic device obtains the capacitance data of different channels in the folding screen to the ground at the current moment as the target self-capacitance data.

[0105] Step 602, determining a second folding angle according to a preset mapping relationship between self-capacity data and a folding angle, and target self-capacity data.

[0106] It should be understood that the mapping relationship between the preset self-capacitance data and the folding angle is obtained based on a plurality of self-capacitance data and corresponding folding angles collected at the same temperature.

[0107] In some embodiments, a mapping relationship between self-capacitance data and folding angles is preset in the electronic device. The mapping relationship can be obtained by solving an equation, or by listing the self-capacitance data and folding angles collected in real time into a table to obtain a mapping relationship in the table. It can also be other methods, which are not specifically limited in the present application.

[0108] In some embodiments, when the mapping relationship between the preset self-capacitance data and the folding angle is a table mapping relationship, the electronic device searches the table according to the target self-capacitance data to obtain the second folding angle; when the mapping relationship between the preset self-capacitance data and the folding angle is a function mapping relationship, the electronic device calculates according to the target self-capacitance data and the function relationship to obtain the second folding angle.

[0109] Step 603, determining whether the target temperature is a preset temperature.

[0110] It should be understood that the preset temperature is some specific temperatures or a temperature range stored in advance in the electronic device.

[0111] Step 604: when the target temperature is the preset temperature, determine the target folding angle according to the sum of the second folding angle and the preset compensation angle.

[0112] In some embodiments, when the target temperature is a preset temperature, the target folding angle is obtained by summing the preset compensation angle in the electronic device and the second folding angle. In other words, a default value of the compensation angle may be stored in the electronic device, and when the target temperature is a preset temperature, the target folding angle is determined based on the default value of the compensation angle.

[0113] In this embodiment, the electronic device first obtains the target temperature and target self-capacitance data at the current moment, and then determines the second folding angle according to the mapping relationship between the preset self-capacitance data and the folding angle, and the target self-capacitance data, and then determines whether the target temperature is the preset temperature. When the target temperature is the preset temperature, the target folding angle is determined according to the sum of the second folding angle and the preset compensation angle. In this method, when the target temperature is the preset temperature, the electronic device performs compensation processing on the folding angle based on the preset compensation angle, which can improve the accuracy of the folding angle calculation when the temperature of the electronic device changes.

[0114] It should be noted that the folding screen in the above embodiment, that is, the touch screen, can also be called a touch screen system. The touch screen system can have its own memory and processor to perform data calculations and can also communicate with the terminal system. For example, please refer to Figure 7 , is a structural diagram of a touch screen system and a terminal system provided by an embodiment of the present application, wherein the touch screen system triggers an interrupt signal through the terminal pin INT, and then obtains data in the touch screen system through the terminal system; the terminal system sets the touch screen system through the serial bus interface (inter-integrated circuit, I2C) serial peripheral interface (serial peripheral interface, SPI) interface.

[0115] In some embodiments, the terminal device system is an Android system, for example, the Android system is divided into different software layers, such as upper layer applications and touch screen drivers. The upper layer applications are responsible for determining the current system status and then issuing different instructions; the touch screen driver is responsible for receiving the instructions issued by the layer application and communicating data with the touch device of the hardware device, that is, the touch screen system.

[0116] In summary, in the method for detecting the folding angle of the folding screen in the embodiment of the present application, the electronic device obtains the system temperature and transmits the temperature information to the touch screen system at a fixed time. The touch screen system further determines the target folding angle based on the current temperature information and the mapping relationship between different preset self-capacitance ranges and folding angles at different preset temperatures, thereby solving the problem of inaccurate calculation of the folding angle by the touch screen collecting self-capacitance data when the temperature changes sharply or at low or high temperatures.

[0117] It should be understood that, although the steps in the above-mentioned flowcharts are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders.
