Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a method, apparatus, electronic device and storage medium for determining the folding angle of a screen. Background Technology

[0002] Currently, foldable electronic devices typically detect the folding angle of the screen using hardware such as Hall sensors and magnets. Specifically, since Hall sensors can detect the strength of a magnetic field, during the screen folding process, a magnet located on one side of the foldable screen gradually approaches the Hall sensor located on the other side. As the magnet gets closer, the magnetic field strength detected by the Hall sensor continuously increases. Therefore, the folding angle of the screen can be determined based on the correlation between the magnetic field strength detected by the Hall sensor and the folding angle.

[0003] However, Hall effect sensors are susceptible to interference from the surrounding magnetic field environment. This interference can affect the detection results of the folding angle of electronic devices, and in severe cases, may even prevent the sensor from making a judgment. For example, when headphones are near an electronic device, the magnetic field strength detected by the Hall effect sensor will be enhanced. As a result, the accuracy of the electronic device in detecting the folding angle of the screen is relatively low. Summary of the Invention

[0004] The purpose of this application is to provide a method, apparatus, electronic device, and storage medium for determining the folding angle of a screen, which can improve the accuracy of electronic devices in detecting the folding angle of a screen.

[0005] In a first aspect, embodiments of this application provide a method for determining the folding angle of a screen. The screen includes a first screen and a second screen, and a photosensitive sensor is disposed below the first screen. The method includes: acquiring a first light intensity collected by the photosensitive sensor during a first time period in a dimming cycle, and a second light intensity collected by the photosensitive sensor during a second time period in the dimming cycle, wherein the screen is in a lit state during the first time period and in a turned-off state during the second time period; obtaining a third light intensity of the screen based on the first and second light intensities, wherein the first light intensity includes ambient light intensity and screen light intensity, and the second light intensity includes ambient light intensity; determining the light intensity of the first screen based on screen information of the first screen; subtracting the third light intensity from the light intensity of the first screen to obtain the light intensity of the second screen; and determining the folding angle of the screen based on the light intensity of the second screen and the screen information of the second screen.

[0006] Secondly, embodiments of this application provide a device for determining the folding angle of a screen. The screen includes a first screen and a second screen, and a photosensitive sensor is disposed below the first screen. The device includes: an acquisition module, a processing module, and a determination module. The acquisition module is used to acquire a first light intensity collected by the photosensitive sensor during a first time period in a dimming cycle, and a second light intensity collected by the photosensitive sensor during a second time period in the dimming cycle. During the first time period, the screen is in an on state, and during the second time period, the screen is in an off state. The processing module is used to obtain a third light intensity of the screen based on the first and second light intensities acquired by the acquisition module. The first light intensity includes ambient light intensity and screen light intensity, and the second light intensity includes ambient light intensity. The determination module is used to determine the light intensity of the first screen based on the screen information of the first screen. The processing module is also used to subtract the third light intensity from the light intensity of the first screen determined by the determination module to obtain the light intensity of the second screen. The determination module is also used to determine the folding angle of the screen based on the light intensity of the second screen obtained by the processing module and the screen information of the second screen.

[0007] Thirdly, embodiments of this application provide an electronic device including a processor and a memory, wherein the memory stores programs or instructions executable on the processor, and the programs or instructions, when executed by the processor, implement the steps of the method described in the first aspect.

[0008] Fourthly, embodiments of this application provide a readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0009] Fifthly, embodiments of this application provide a chip, the chip including a processor and a communication interface, the communication interface being coupled to the processor, the processor being used to run programs or instructions to implement the method as described in the first aspect.

[0010] In a sixth aspect, embodiments of this application provide a computer program product stored in a storage medium, which is executed by at least one processor to implement the method described in the first aspect.

[0011] In this embodiment, since the photosensitive sensor can collect the total intensity of the screen light intensity and the ambient light intensity when the screen is on during the dimming cycle, and can collect the ambient light intensity when the screen is off during the dimming cycle, the screen light intensity, i.e., the aforementioned third light intensity, can be obtained based on the total intensity of the screen light intensity and the ambient light intensity, as well as the ambient light intensity. Simultaneously, since the photosensitive sensor is located below the first screen, it can detect the light intensity of the first screen regardless of the screen's folding angle. The light intensity of the second screen detected by the photosensitive sensor changes with the screen's folding angle. Therefore, this application can obtain the light intensity of the second screen at the current folding angle by subtracting the light intensity of the first screen determined based on the screen information of the first screen from the total screen light intensity. Since the light intensity of the second screen is related to the screen's folding angle, the screen folding angle can be determined based on the light intensity of the second screen and the screen information of the second screen. Furthermore, since this application determines the screen folding angle based on the photosensitive sensor, and the photosensitive sensor does not need to consider interference from the surrounding magnetic field environment, the accuracy of the electronic device in detecting the screen folding angle is improved.

[0022] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0023] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] The method for determining the folding angle of the screen provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0025] The method for determining the folding angle of the screen in this application embodiment can be applied to scenarios involving detecting the folding angle of the screen.

[0026] Currently, foldable electronic devices typically detect the folding angle of the screen using hardware such as Hall sensors and magnets. Specifically, since Hall sensors can detect the strength of a magnetic field, during the screen folding process, a magnet located on one side of the foldable screen gradually approaches the Hall sensor located on the other side. As the magnet gets closer, the magnetic field strength detected by the Hall sensor continuously increases. Therefore, the folding angle of the screen can be determined based on the correlation between the magnetic field strength detected by the Hall sensor and the folding angle.

[0027] However, Hall effect sensors are susceptible to interference from the surrounding magnetic field environment. This interference can affect the detection results of the folding angle of electronic devices, and in severe cases, may even prevent the sensor from making a judgment. For example, when headphones are near an electronic device, the magnetic field strength detected by the Hall effect sensor will be enhanced. As a result, the accuracy of the electronic device in detecting the folding angle of the screen is relatively low.

[0028] In the screen folding angle determination method, apparatus, electronic device, and storage medium provided in this application embodiment, since the photosensitive sensor can collect the total intensity of the screen light intensity and ambient light intensity when the screen is on during the dimming cycle, and can collect the ambient light intensity when the screen is off during the dimming cycle, the screen light intensity, i.e., the aforementioned third light intensity, can be obtained based on the total intensity of the screen light intensity and ambient light intensity, as well as the ambient light intensity. Simultaneously, since the photosensitive sensor is located below the first screen, it can detect the light intensity of the first screen regardless of the screen folding angle. The light intensity of the second screen detected by the photosensitive sensor changes with the screen folding angle. Therefore, this application can obtain the light intensity of the second screen at the current folding angle by subtracting the light intensity of the first screen determined based on the screen information of the first screen from the total screen light intensity. Since the light intensity of the second screen is related to the screen folding angle, the screen folding angle can be determined based on the light intensity of the second screen and the screen information of the second screen. Furthermore, since this application determines the folding angle of the screen based on a photosensitive sensor, and the photosensitive sensor does not need to consider the interference of the surrounding magnetic field environment, the accuracy of the electronic device in detecting the folding angle of the screen is improved.

[0029] Furthermore, the Hall sensor used in the current solution requires additional hardware, which incurs certain hardware costs. In contrast, this application reuses the photosensitive sensor built into the electronic device to detect the light intensity of the screen, achieving low-cost detection of the folding angle.

[0030] For example, the aforementioned photosensitive sensor can detect light and is used to detect the light intensity of the screen of an electronic device. This photosensitive sensor, also known as a photoelectric sensor or phototransistor, is a device that converts light signals into electrical signals.

[0031] For example, typically only one photosensor is placed in the screen of an electronic device.

[0032] For example, the aforementioned photosensor is disposed below the screen of an electronic device.

[0033] For example, such as Figure 1 As shown, the electronic device is in a fully unfolded state. The screen of the electronic device includes a first screen 11 and a second screen 12. A photosensitive sensor 13 is disposed below the first screen 11.

[0034] It is understandable that during the process of unfolding and folding the screen of an electronic device, the photosensitive sensor 13 initially can only receive screen light from the screen side 12, but gradually can receive screen light from the screen side 11. The intensity of the screen light collected will gradually increase, and when the screen of the electronic device is completely folded, the intensity of the screen light collected by the photosensitive sensor 13 will reach its maximum value.

[0035] The execution subject of the screen folding angle determination method provided in this application embodiment can be a screen folding angle determination device, which can be an electronic device, or a functional module or entity in the electronic device. The following uses an electronic device as an example to illustrate the technical solution provided in this application embodiment.

[0036] This application provides a method for determining the folding angle of a screen. Figure 2 A flowchart illustrating a method for determining the folding angle of a screen according to an embodiment of this application is shown. This method can be applied to an electronic device whose screen includes a first screen and a second screen, with a photosensor disposed below the first screen. Figure 2 As shown, the method for determining the folding angle of the screen provided in this application embodiment may include the following steps 201 to 205.

[0037] Step 201: Obtain the first light intensity collected by the photosensitive sensor during the first time period of the dimming cycle, and the second light intensity collected by the photosensitive sensor during the second time period of the dimming cycle.

[0038] In the embodiments of this application, the screen is lit during the first time period and turned off during the second time period.

[0039] In the embodiments of this application, the first light intensity includes ambient light intensity and screen light intensity, and the second light intensity includes ambient light intensity.

[0040] In some embodiments of this application, the first time period and the second time period are consecutive time periods.

[0041] In some embodiments of this application, when the screen power of the electronic device is on, the screen includes a lit state and a turned-off state.

[0042] Understandably, current screen dimming methods include Pulse Width Modulation (PWM). Under this dimming method, the screen brightness can be adjusted by controlling the periodic on and off of the screen. Since each cycle is very short and the human eye has the persistence of vision effect, the screen appears to be constantly on, but in reality, the screen is rapidly flickering between "on-off-on-off".

[0043] It is understandable that when the screen is briefly lit, it is called the lit state, and when the screen is briefly off, it is called the off state. This off state is different from the screen-off state when the electronic device's screen power is off.

[0044] For example, when the screen brightness is 70%, the screen turns off for 0.3 milliseconds every 0.7 milliseconds it is on. If you want the screen brightness to be reduced to 10%, you can control the screen to turn off for 0.9 milliseconds every 0.1 milliseconds it is on.

[0045] For example, such as Figure 3 As shown in the figure, which is represented by a PWM waveform, when the brightness of the electronic device's screen is 70%, the screen turns off for 0.3 milliseconds every 0.7 milliseconds it is on.

[0046] It should be noted that when the screen of an electronic device is powered on, each consecutive cycle of the screen turning on and off is called a dimming cycle, or a flicker cycle.

[0047] In some embodiments of this application, when the screen of an electronic device is lit, a photosensor can collect the screen light and the ambient light penetrating the screen to obtain a first light intensity.

[0048] For example, the aforementioned first light intensity can be expressed by the following formula:

[0049] S on =I screen +I ambient Formula 1

[0050] Among them, I screen For screen light intensity, I ambient α represents the ambient light intensity, and α represents the screen transmittance coefficient.

[0051] In some embodiments of this application, when the screen of the electronic device is off, the photosensitive sensor can collect ambient light, i.e., natural light, that penetrates the screen to obtain a second light intensity, thereby avoiding interference from screen light.

[0052] For example, the second light intensity mentioned above can be expressed by the following formula:

[0053] S off =I ambient Formula 2

[0054] Among them, I ambient α represents the ambient light intensity, and α represents the screen transmittance coefficient.

[0055] In some embodiments of this application, combined with Figure 2 ,like Figure 4 As shown, step 201 above can be specifically implemented through step 201a below.

[0056] Step 201a: If no touch screen operation is detected during the dimming cycle, the electronic device acquires the first light intensity collected by the photosensitive sensor during the first time period of the dimming cycle, and the second light intensity collected by the photosensitive sensor during the second time period of the dimming cycle.

[0057] In some embodiments of this application, the electronic device can detect in real time whether there is a touch screen operation. When no touch screen operation is detected, it can then acquire the first light intensity collected by the photosensitive sensor during the first time period of the dimming cycle, and the second light intensity collected by the photosensitive sensor during the second time period of the dimming cycle.

[0058] It is understandable that when there is touch screen operation on electronic devices, objects may block the light emission path, causing the first and second light intensities collected by the photosensitive sensor to be inaccurate. Therefore, it is necessary to obtain the first light intensity collected by the photosensitive sensor in the first time period of the dimming cycle and the second light intensity collected by the photosensitive sensor in the second time period of the dimming cycle when there is no touch screen operation.

[0059] In some embodiments of this application, the object that obstructs the light emission path can be at least one of the following: a hand, a stylus, a watch, etc.

[0060] Thus, since the electronic device acquires the first light intensity collected by the photosensitive sensor in the first time period of the dimming cycle and the second light intensity collected by the photosensitive sensor in the second time period of the dimming cycle only when there is no touch screen operation, the accuracy of the acquired first and second light intensities is guaranteed.

[0061] Step 202: The electronic device obtains the third light intensity of the screen based on the first light intensity and the second light intensity.

[0062] In some embodiments of this application, the third light intensity mentioned above includes the screen light intensity.

[0063] In some embodiments of this application, the electronic device can subtract the first light intensity from the second light intensity to calculate the third light intensity.

[0064] It is understandable that when the screen of an electronic device is lit, the photosensitive sensor cannot distinguish the collected light. Therefore, the screen light intensity can be calculated based on the ambient light intensity obtained when the screen is off.

[0065] For example, the electronic device can subtract the first light intensity from the second light intensity to calculate the third light intensity, as shown in Formula 3:

[0066] I screen =S on -S off Formula 3

[0067] Among them, I screen The third light intensity, S on S is the first light intensity. off This is the second light intensity.

[0068] In some embodiments of this application, the dimming cycle includes N dimming cycles; the above step 201 can be specifically implemented by the following step 201b.

[0069] Step 201b: The electronic device acquires the first light intensity collected by the photosensitive sensor in the first time period of each of the N dimming cycles, and acquires the second light intensity collected by the photosensitive sensor in the second time period of each dimming cycle.

[0070] In the embodiments of this application, N is an integer greater than 1.

[0071] It can be understood that within each of the above N dimming cycles, the electronic device acquires the first light intensity collected by the photosensitive sensor in the first time period and the second light intensity collected by the photosensitive sensor in the second time period.

[0072] It should be noted that the detailed steps for the first light intensity and the second light intensity can be found in the description in the above embodiments, and will not be repeated here.

[0073] In some embodiments of this application, step 202 can be specifically implemented by the following steps 202a and 202b.

[0074] Step 202a: The electronic device subtracts the first light intensity corresponding to the first dimming cycle from the second light intensity corresponding to the first dimming cycle to obtain the fourth light intensity corresponding to the first dimming cycle.

[0075] In the embodiments of this application, the first dimming cycle is one of N dimming cycles.

[0076] In some embodiments of this application, the fourth light intensity is the screen light intensity.

[0077] It should be noted that for the detailed steps of calculating the fourth light intensity corresponding to the first dimming cycle, please refer to the description in step 202 above where the electronic device subtracts the first light intensity from the second light intensity to calculate the third light intensity, which will not be repeated here.

[0078] Step 202b: The electronic device averages the N fourth light intensities corresponding to N dimming cycles to obtain the third light intensity.

[0079] It is understandable that the electronic device can subtract the first light intensity from the second light intensity corresponding to each of the N dimming cycles to obtain the fourth light intensity corresponding to each dimming cycle. Then, the fourth light intensities corresponding to each dimming cycle can be added together to calculate the average value to obtain the aforementioned third light intensity.

[0080] For example, if N is 3, the N fourth light intensities corresponding to the above N dimming cycles are A, B, and C, respectively. The electronic device can calculate the third light intensity = (A+B+C) / 3.

[0081] Thus, since the electronic device obtains the first light intensity and the second light intensity corresponding to each of the N dimming cycles, and then calculates the third light intensity corresponding to each dimming cycle based on the first light intensity and the second light intensity corresponding to each dimming cycle, and then determines the folding angle of the screen based on the average of the N third light intensities corresponding to the N dimming cycles, the power of the electronic device is saved.

[0082] Step 203: The electronic device determines the light intensity of the first screen based on the screen information of the first screen.

[0083] In some embodiments of this application, since the photosensitive sensor is located below the first screen, the photosensitive sensor can detect the light intensity of the first screen regardless of how the folding angle of the screen changes. Therefore, the electronic device can determine the light intensity of the first screen based on the screen information of the first screen.

[0084] In some embodiments of this application, the screen information of the first screen includes: the screen brightness of the first screen and the color value of the pixels in the first screen; the above step 203 can be specifically implemented by the following steps 203a to 203c.

[0085] Step 203a: The electronic device calculates the luminous intensity of the first pixel based on the screen brightness of the first screen and the color value of the first pixel in the first screen.

[0086] In the embodiments of this application, the first pixel is a pixel in the first screen.

[0087] For example, an electronic device can calculate the luminous intensity of the first pixel using Formula 4:

[0088]

[0089] Where DC is the screen brightness of the first screen, DC max c is the maximum brightness of the first screen.i γ is a coefficient related to the color value of the first pixel in the first screen. i It is an index related to the color value of the first pixel in the first screen.

[0090] It should be noted that different color values ​​of pixels correspond to different values ​​of c and γ.

[0091] For example, taking 8-bit as an example, the maximum screen brightness DC max The value is 255, and the screen brightness DC is a value between 0 and 255.

[0092] For example, the coefficients c and the exponent γ mentioned above are constants determined through production calibration.

[0093] Step 203b: The electronic device weights the luminous intensity of the first pixel based on the luminous contribution weight of the first pixel to obtain the first luminous intensity of the first pixel.

[0094] In the embodiments of this application, the light emission contribution weight of the first pixel is related to the position of the first pixel in the first screen.

[0095] For example, an electronic device can calculate the first luminous intensity of the first pixel using Formula 5:

[0096]

[0097] For example, W i (x,y) represents the luminous contribution weight of the first pixel.

[0098] For example, as the first pixel moves further away from the photosensor, W i The smaller (x,y) is, the smaller it becomes, with a minimum value of 0. And the closer W is to the photosensor, the better. i The larger (x,y) is, the greater W is when the first pixel is directly above the photosensitive sensor. i (x,y) reaches its maximum, W i (x,y) can be determined through prior fitting and production calibration.

[0099] Step 203c: The electronic device sums up the first luminous intensity of each pixel in the first screen to obtain the light intensity of the first screen.

[0100] For example, the electronic device can calculate the light intensity of the first screen using Formula Six:

[0101]

[0102] in, Let (x, y) be the i-th pixel in the first screen. i The first luminous intensity.

[0103] Thus, since the electronic device can calculate the first luminous intensity of each pixel based on the luminous contribution weight of each pixel in the first screen, and then accumulate the first luminous intensity of each pixel to obtain the light intensity of the first screen, the reliability of determining the light intensity of the first screen is improved.

[0104] Step 204: The electronic device subtracts the light intensity of the first screen from the third light intensity to obtain the light intensity of the second screen.

[0105] In some embodiments of this application, since the light intensity of the first screen and the third light intensity are known, the light intensity of the second screen can be determined based on Formula 7.

[0106] N B =NN A Formula 7

[0107] Where, N B N represents the light intensity of the second screen. A Let N be the light intensity of the first screen and N be the light intensity of the third screen.

[0108] Step 205: The electronic device determines the folding angle of the screen based on the light intensity of the second screen and the screen information of the second screen.

[0109] It is understandable that since the light intensity of the second screen is related to the folding angle of the screen, the folding angle of the screen can be determined based on the light intensity of the second screen and the screen information of the second screen.

[0110] In some embodiments of this application, the screen information of the second screen includes: the screen brightness of the second screen and the color value of each pixel in the second screen; combined with Figure 2 ,like Figure 5 As shown, step 205 above can be implemented through step 205a below.

[0111] Step 205a: The electronic device determines the folding angle of the screen based on the light intensity of the second screen, the screen brightness of the second screen, the color value of each pixel in the second screen, and the first formula.

[0112] In the embodiments of this application, the first formula is as follows:

[0113]

[0114] Where, N B Let be the light intensity of the second screen, i∈{1,2,3…M}, M be the total number of pixels in the second screen, α be the screen transmittance coefficient, and DC be the screen brightness of the second screen. maxc is the maximum brightness of the second screen. i γ is a coefficient related to the color value of the i-th pixel in the second screen. i The exponent associated with the color value of the i-th pixel in the second screen, θ, is the screen folding angle, and W i (x,y,θ) represents the luminous contribution weight of the i-th pixel in the second screen when the folding angle is θ.

[0115] It is understandable that, since the light intensity of the second screen, the brightness of the second screen, and the color value of each pixel in the second screen are known, the electronic device can substitute the light intensity of the second screen, the brightness of the second screen, the exponent γ and the coefficient c related to the color value of each pixel in the second screen into the above formula to calculate the folding angle of the screen.

[0116] In the method for determining the folding angle of the screen provided in this application embodiment, since the photosensitive sensor can collect the total intensity of the screen light intensity and the ambient light intensity when the screen is on during the dimming cycle, and can collect the ambient light intensity when the screen is off during the dimming cycle, the screen light intensity, i.e., the aforementioned third light intensity, can be obtained based on the total intensity of the screen light intensity and the ambient light intensity, as well as the ambient light intensity. Simultaneously, since the photosensitive sensor is located below the first screen, it can detect the light intensity of the first screen regardless of the screen's folding angle. The light intensity of the second screen detected by the photosensitive sensor changes with the screen's folding angle. Therefore, this application can obtain the light intensity of the second screen at the current folding angle by subtracting the light intensity of the first screen determined based on the screen information of the first screen from the total screen light intensity. Since the light intensity of the second screen is related to the screen's folding angle, the screen folding angle can be determined based on the light intensity of the second screen and the screen information of the second screen. Furthermore, since this application determines the folding angle of the screen based on a photosensitive sensor, and the photosensitive sensor does not need to consider the interference of the surrounding magnetic field environment, the accuracy of the electronic device in detecting the folding angle of the screen is improved.

[0117] In some embodiments of this application, if the intensity of the third light obtained remains unchanged within a preset number of times, the electronic device may not need to determine the folding angle of the screen.

[0118] It is understandable that since the intensity of the third light obtained within the preset number of times remains unchanged, it can be assumed that the folding angle of the screen has not changed. Therefore, it is not necessary to judge the folding angle of the screen, thereby reducing power consumption.

[0119] For example, when the intensity of the acquired third light changes, the electronic device can begin to determine the folding angle of the screen.

[0120] In some embodiments of this application, when the folding angle is less than or equal to a first threshold, the electronic device determines that the screen of the electronic device has been fastened, that is, it is in a fully folded state.

[0121] In some embodiments of this application, the first threshold is obtained by subtracting the angle calculation error from the folding angle when the screen is fully folded.

[0122] In some embodiments of this application, the screen of the electronic device being in a fully folded state can be understood as follows: the two screens of the electronic device are folded together and hidden inside, and the folding angle of the screen of the electronic device is infinitely close to 0.

[0123] For example, combined with Figure 1 ,like Figure 6 As shown, the electronic device is in a fully folded state, with the second screen 12 of the electronic device folded 180° along the common axis x, so that the first screen 11 and the second screen 12 are folded and hidden inside.

[0124] In some embodiments of this application, when the folding angle is greater than a first threshold, the electronic device determines that the screen of the electronic device is not fastened, that is, it is in an incompletely folded state.

[0125] In some embodiments of this application, the screen of the electronic device being in a partially folded state can be understood as: the two screens of the electronic device are not attached together, and the folding angle of the screen of the electronic device is greater than 0.

[0126] For example, combined with Figure 1 ,like Figure 7 As shown, the electronic device is in a partially folded state, and the folding angle between the first screen 11 and the second screen 12 of the electronic device is β°.

[0127] In some embodiments of this application, when the electronic device determines that the screen of the electronic device has been closed, it can output the status information that the screen has been closed to the operating system.

[0128] In some embodiments of this application, when the folding angle is greater than a first threshold, the electronic device may also output the folding angle to the operating system.

[0129] In some embodiments of this application, the acquisition frequency of the aforementioned photosensitive sensor is a first frequency. The method for determining the folding angle of the screen provided in the embodiments of this application may further include the following step 301.

[0130] Step 301: When the camera application is running, or when the application running in the foreground is detected to support split-screen mode, the electronic device adjusts the sampling frequency of the photosensor from the first frequency to the second frequency.

[0131] In the embodiments of this application, the second frequency is higher than the first frequency, and the second frequency is determined based on the application running in the foreground.

[0132] It is understandable that when running a camera application, users may fold the screen of their electronic device to a certain preset folding angle to trigger the electronic device to display a camera preview interface on one side of the screen and shooting controls on the other side, so that users can take pictures. Therefore, when running a camera application, the real-time detection of the screen folding angle is required to be high, so the sampling frequency of the photosensitizer can be increased.

[0133] Similarly, when it is detected that the application running in the foreground supports split-screen mode, the user may fold the screen of the electronic device to a certain preset folding angle to trigger the electronic device to enter split-screen mode. Therefore, when it is detected that the application running in the foreground supports split-screen mode, the real-time detection of the screen folding angle is required to be high, so the sampling frequency of the photosensitive sensor can be increased.

[0134] In some embodiments of this application, for an electronic device, a certain function in the application can be triggered by adjusting the screen of the electronic device to a certain preset folding angle. When the electronic device detects that the application is running in the foreground, the electronic device can adjust the sampling frequency of the photosensitive sensor from a first frequency to a second frequency.

[0135] In some embodiments of this application, different applications have different real-time requirements for detecting the screen folding angle. Therefore, different applications can correspond to different acquisition frequencies. For example, the second frequency corresponding to the camera application can be higher than the second frequency corresponding to the application that supports split-screen mode.

[0136] In some embodiments of this application, when the application requires real-time detection of the screen folding angle to be performed once every t milliseconds, the second frequency T≤t.

[0137] For example, an electronic device can determine the real-time detection requirements of the screen folding angle based on the number of times the user folds the screen during the application's historical runtime.

[0138] Thus, when the application being run has high real-time requirements for detecting the folding angle of the screen, the electronic device can adjust the sampling frequency of the photosensitive sensor from the first frequency to the second frequency, thereby improving the timeliness of the electronic device in detecting the folding angle of the folding screen.

[0139] In some embodiments of this application, the electronic device stops detecting the screen's folding angle when the screen power is off.

[0140] It should be noted that the screen folding angle determination method provided in this application embodiment can be executed by a screen folding angle determination device. This application embodiment uses a screen folding angle determination device executing the screen folding angle determination method as an example to illustrate the screen folding angle determination device provided in this application embodiment.

[0141] Figure 8 This illustration shows a possible structural diagram of a screen folding angle determination device according to an embodiment of this application. The screen folding angle determination device is applied to an electronic device, the screen of which includes a first screen and a second screen, and a photosensor is disposed below the first screen, such as... Figure 8 As shown, the device 70 for determining the folding angle of the screen may include: an acquisition module 71, a processing module 72, and a determination module 73.

[0142] The acquisition module 71 is used to acquire the first light intensity collected by the photosensitive sensor during the first time period of the dimming cycle, and the second light intensity collected by the photosensitive sensor during the second time period of the dimming cycle. The screen is in the lit state during the first time period and the screen is in the off state during the second time period.

[0143] The processing module 72 is used to obtain the third light intensity of the screen based on the first light intensity and the second light intensity obtained by the acquisition module 71. The first light intensity includes the ambient light intensity and the screen light intensity, and the second light intensity includes the ambient light intensity.

[0144] The determining module 73 is used to determine the light intensity of the first screen based on the screen information of the first screen;

[0145] The processing module 72 is also used to subtract the light intensity of the first screen determined by the determining module 73 from the third light intensity to obtain the light intensity of the second screen;

[0146] The determining module 73 is also used to determine the folding angle of the screen based on the light intensity of the second screen and the screen information of the second screen obtained by the processing module 72.

[0147] This application provides a device for determining the folding angle of a screen. Since a photosensitive sensor can collect the total intensity of the screen light intensity and ambient light intensity when the screen is on during a dimming cycle, and can collect the ambient light intensity when the screen is off during a dimming cycle, the screen light intensity (the aforementioned third light intensity) can be obtained based on the total intensity of the screen light intensity and ambient light intensity, as well as the ambient light intensity. Simultaneously, since the photosensitive sensor is located below the first screen, it can detect the light intensity of the first screen regardless of the screen's folding angle. The light intensity of the second screen detected by the photosensitive sensor changes with the screen's folding angle. Therefore, this application can obtain the light intensity of the second screen at the current folding angle by subtracting the total screen light intensity from the light intensity of the first screen determined based on the screen information of the first screen. Since the light intensity of the second screen is related to the screen's folding angle, the screen folding angle can be determined based on the light intensity of the second screen and the screen information of the second screen. Furthermore, since this application determines the folding angle of the screen based on a photosensitive sensor, and the photosensitive sensor does not need to consider the interference of the surrounding magnetic field environment, the accuracy of the electronic device in detecting the folding angle of the screen is improved.

[0148] In one possible implementation, the screen information of the first screen includes: the screen brightness of the first screen and the color values ​​of the pixels in the first screen; the determining module 73 is specifically used to calculate the luminous intensity of the first pixel based on the screen brightness of the first screen and the color values ​​of the first pixel in the first screen, wherein the first pixel is a pixel in the first screen; and to weight the luminous intensity of the first pixel based on the luminous contribution weight of the first pixel to obtain the first luminous intensity of the first pixel, wherein the luminous contribution weight of the first pixel is related to the position of the first pixel in the first screen; and to accumulate the first luminous intensity of each pixel in the first screen to obtain the light intensity of the first screen.

[0149] In one possible implementation, the dimming cycle includes N dimming cycles; the acquisition module 71 is specifically used to acquire the first light intensity collected by the photosensitive sensor in a first time period within each of the N dimming cycles, and to acquire the second light intensity collected by the photosensitive sensor in a second time period within each dimming cycle, where N is an integer greater than 1. The processing module 72 is specifically used to subtract the first light intensity corresponding to the first dimming cycle from the second light intensity corresponding to the first dimming cycle to obtain the fourth light intensity corresponding to the first dimming cycle, where the first dimming cycle is one of the N dimming cycles; and to average the N fourth light intensities corresponding to the N dimming cycles to obtain the third light intensity.

[0150] In one possible implementation, the acquisition module 71 is specifically used to acquire the first light intensity collected by the photosensitive sensor during a first time period in the dimming cycle and the second light intensity collected by the photosensitive sensor during a second time period in the dimming cycle when no touch screen operation is detected during the dimming cycle.

[0151] In one possible implementation, the sampling frequency of the photosensitive sensor is a first frequency; the screen folding angle determination device 70 provided in this application embodiment further includes: an adjustment module; the adjustment module is used to adjust the sampling frequency of the photosensitive sensor from the first frequency to a second frequency when a camera application is running, or when it is detected that the application running in the foreground supports split-screen mode, the second frequency being higher than the first frequency, and the second frequency being determined based on the application running in the foreground.

The electronic device can be a terminal or other devices besides a terminal. For example, the electronic device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a server, network attached storage (NAS), personal computer (PC), television (TV), ATM, or self-service machine, etc. This application embodiment does not specifically limit the device.

Simultaneously, because the photosensitive sensor is located below the first screen, it can detect the light intensity of the first screen regardless of the screen's folding angle. The light intensity of the second screen detected by the photosensitive sensor changes with the screen's folding angle. Therefore, this application can obtain the light intensity of the second screen at the current folding angle by subtracting the total screen light intensity from the light intensity of the first screen determined based on the screen information of the first screen. Since the light intensity of the second screen is related to the screen's folding angle, the screen folding angle can be determined based on the light intensity of the second screen and the screen information of the second screen. Furthermore, since this application determines the screen folding angle based on a photosensitive sensor, and the photosensitive sensor does not need to consider interference from the surrounding magnetic field environment, the accuracy of the electronic device in detecting the screen folding angle is improved.
