[0004] Currently, many electronic devices are provided with ambient light sensors (or light sensing devices) for detecting the light intensity (referred to as illuminance) of the external environment, so as to adjust the brightness of the display screen of the electronic device using the ambient light illuminance, and to ensure the comfort of the user in viewing the display content of the screen under different illuminance. In the traditional design scheme, one light sensing device is generally provided on one screen.

[0005] With the evolution of the physical form of electronic devices, for example, mobile phones, from a straight single screen to a foldable screen, new requirements are put forward for the design and use of light sensing devices. SUMMARY

[0006] The present application provides a display control method and electronic device for switching light sensing devices according to the attitude change of the electronic device, so as to control the display brightness of the foldable screen of the electronic device using the ambient light information detected by the corresponding light sensing device, thereby meeting the dimming requirements under different attitudes.

[0007] In a first aspect, the embodiments of the present application provide a display control method applied to an electronic device with a foldable screen, the foldable screen being a three-fold screen, and at least two light sensing devices of the electronic device being disposed on different display areas of the three-fold screen. The method can include: in a case where the three-fold screen is in a first attitude, controlling the display brightness of the three-fold screen using ambient light information detected by a first light sensing device of the at least two light sensing devices; determining that the three-fold screen changes from the first attitude to a second attitude, the second attitude being associated with a second light sensing device of the at least two light sensing devices; and in a case where the three-fold screen is in the second attitude, controlling the display brightness of the three-fold screen using ambient light information detected by the second light sensing device.

[0009] In a possible implementation, the tri-fold screen can include a first display area, a second display area, and a third display area, the first display area and the third display area are connected through a first folding axis, the second display area and the third display area are connected through a second folding axis, the at least two light sensing devices are arranged in the first display area and the second display area, and no light sensing device is arranged on the third display area, wherein the first posture and the second posture correspond to different display postures of the tri-fold screen relative to the user's visual angle in the same physical posture; or the first posture and the second posture correspond to different physical postures of the tri-fold screen.

[0069] The resource manager provides various resources for the application program, such as localized strings, icons, pictures, layout files, video files, and the like.

[0070] The notification manager makes the application program capable of displaying notification information in the status bar, and can be used to convey a message of the notification type, which can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the completion of downloading, message reminders, and the like. The notification manager can also be a notification in the form of a chart or a scroll bar text appearing in the top status bar of the system, for example, a notification of an application program running in the background, and can also be a notification in the form of a dialogue window appearing on the screen. For example, the text information is prompted in the status bar, a prompt sound is emitted, the electronic device vibrates, the indicator light flashes, and the like.

[0071] The runtime includes a core library and a virtual machine. The runtime is responsible for the scheduling and management of the operating system.

[0072] The core library includes two parts: one part is the function function required to be called by the java language, and the other part is the core library of the operating system. The application program layer and the application program framework layer run in the virtual machine. The virtual machine executes the java files of the application program layer and the application program framework layer into binary files. The virtual machine is used to perform the management of the object life cycle, the management of the stack, the management of the thread, the management of the security and exception, and the garbage collection, and the like.

[0073] The system library can include a plurality of functional modules. For example, a surface manager, media libraries, a three-dimensional graphics processing library (e.g., OpenGL ES), a 2D graphics engine (e.g., SGL), etc.

[0074] The surface manager is used to manage the display subsystem and provides a plurality of applications with a fusion of 2D and 3D layers.

[0075] The media libraries support a plurality of commonly used audio, video format playback and recording, and static image files, etc. The media libraries can support a plurality of audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0076] The three-dimensional (3D) graphics processing library is used to implement three-dimensional graphics drawing, image rendering, composition, and layer processing, etc. The two-dimensional (2D) graphics engine is a drawing engine for 2D drawing.

[0077] In some embodiments, the three-dimensional graphics processing library can be used to draw a three-dimensional motion trajectory image, and the 2D graphics engine can be used to draw a two-dimensional motion trajectory image. In some embodiments, the three-dimensional graphics processing library and the two-dimensional graphics processing engine can be integrated into one graphics processor, which is not limited in the embodiments of the present application.

[0078] The kernel layer is a layer between hardware and software. The kernel layer at least includes a display driver, a camera driver, an audio driver, and a sensor driver.

[0079] The hardware layer can include various sensors, such as an acceleration sensor, a gyroscope sensor, a rotation vector sensor, etc., which can be used to detect the posture (e.g., including a motion posture or a physical posture, etc.) of the electronic device, so as to select the light sensing device to be used in combination with the posture of the electronic device, and use the light sensing device to detect the ambient light (Ambient Light) information to control the brightness of the display screen, thereby ensuring the comfort of the user to see the screen display content under different illuminations.

[0080] It should be noted that the structure shown in FIG. 1 and FIG. 2 is only an example of the electronic device provided by the embodiments of the present application, and cannot limit the electronic device provided by the embodiments of the present application in any way. In specific implementations, the electronic device can have more or fewer devices or modules than the structure shown in FIG. 1 or FIG. 2, or devices or modules for implementing the same function can have other names, which are not limited in the embodiments of the present application.

[0081] FIG. 3 is a system architecture diagram to which a display control method provided in an embodiment of the present application is applicable. Referring to FIG. 3, the operating system of the electronic device can adopt a five-layer hierarchical structure, and a hardware abstraction layer (HAL) can be further included between the framework layer and the kernel layer to abstract hardware, thereby hiding hardware interface details of a specific platform, providing a virtual hardware platform for the operating system, and enabling the operating system to be hardware-independent and thus portable on multiple platforms. In a colloquial sense, the hardware abstraction layer can perform actions to control hardware.

[0082] For example, the HAL can include a driver and an interface library of a processor, a peripheral, a sensor, etc. The HAL can include a display engine of the processor, a sensor driver, and an ambient light sensor driver. The sensor driver can acquire posture information of the electronic device from a sensor of the hardware layer. The ambient light sensor driver can acquire ambient light information of an environment in which the electronic device is located from an ambient light sensor of the hardware layer. The display engine can acquire posture information of the electronic device from the sensor driver, thereby recognizing a posture change of the electronic device, and perform display control of the electronic device in combination with the posture change of the electronic device. For example, the display engine can switch an ambient light sensor to be used at a current time in combination with the posture change of the electronic device, and control display brightness of a foldable screen of the electronic device using ambient light information acquired by the currently used ambient light sensor.

[0083] In a specific implementation, the hardware layer of the electronic device can include related hardware of a sensor hub, such as a sensor (or posture sensor) for detecting a device posture and an ambient light sensor (or light sensing device) for detecting ambient light information.

[0084] The sensor, such as a gyroscope sensor, an acceleration sensor, a hinge, a distance sensor, etc. shown in FIG. 1, or other sensors (such as a HALL sensor, not shown in the figure), can be used to detect a use posture of the electronic device and provide posture information of the electronic device to an upper-layer driver. The electronic device can include at least two light sensing devices, which can be disposed on different display areas of the foldable screen, and used to detect ambient light of an environment in which the electronic device is located and provide ambient light information to an upper-layer driver.

[0085] For example, the hinge sensor can be used to provide a hinge angle, which is a folding angle of different display regions of the foldable screen of the electronic device, and the hinge angle can be used to determine a physical posture of the foldable screen of the electronic device, including but not limited to: a fully unfolded posture, a fully folded posture, at least one half-folded posture, and the like. Or for example, the gyroscope sensor, the acceleration sensor, the distance sensor, and the like can be used to provide different display posture information of the electronic device relative to the user's visual angle in the same physical posture. Taking an example of representing the different display posture information of the electronic device relative to the user's visual angle in the same physical posture by a device posture angle of the electronic device, the device posture angle may, for example, include at least one of: a pitch angle, a roll angle, or a yaw angle. Taking the roll angle as an example, when the foldable screen of the electronic device is in a fully unfolded posture, the display posture of the electronic device can include a landscape display posture and a portrait display posture, which can be obtained by rotating the electronic device based on the roll angle. Similarly, when the foldable screen of the electronic device is in a fully folded posture or any one of a half-folded posture, the display posture of the electronic device can also include a landscape display posture and a portrait display posture, which can be obtained by rotating the electronic device based on the roll angle. Based on different postures of the electronic device, the display engine can control the corresponding light sensing device to work to collect ambient light information, and control the display brightness of the foldable screen of the electronic device by using the ambient light information collected by the corresponding ambient light sensor. In the following, various device postures of the embodiments of the present application and the corresponding manner of different device postures and light sensing devices will be introduced with reference to the accompanying drawings, which will not be described here.

[0086] The kernel layer of the electronic device can be an implementation layer of a software development kit (SDK) of related hardware of the DSS, and can also include a DDIC driver, which is used to provide necessary support and services for the display engine of the hardware abstraction layer, to provide a stable, safe, and efficient running environment for the upper-layer application. The kernel layer can also include an input hub, which can obtain information from the DDIC driver, the ambient light sensor APP, and the like when in operation.

[0087] The framework layer of the electronic device can also include a framework of the display engine service, a framework of the light service, and a sensor network inspection framework (SNIF) of the sensor hub.

[0088] The upper layer of the framework layer of the electronic device can be an application layer, for example, including APPs of the electronic device for implementing various services, or an ambient light sensor APP. The ambient light sensor APP can implement relevant calls through an API or a function provided by the sensor hub SNIF of the framework layer, to obtain relevant information from a sensor driver or an ambient light sensor driver, and can provide the obtained information to the processor through the input hub, so that the processor implements a display engine service or a light service based on the information. Alternatively, the upper layer of the framework layer of the electronic device can provide input information, for example, ambient light information, obtained via a communication interface. Alternatively, the upper layer of the framework layer of the electronic device can also include a backlight source of the foldable screen, which can be driven and controlled by the DDIC to control the display brightness of the foldable screen.

[0089] When the display engine of the processor implements the display control method of the embodiments of the present application, it can implement relevant calls of the display engine service through an API or a function provided by the framework layer. At the same time, the display engine can also send corresponding control instructions to the DDIC driver to implement the display control function of the embodiments of the present application. For example, the display engine can send corresponding control instructions to the DDIC driver using ambient light information collected by the currently used ambient light sensor, so that the DDIC driver enhances or reduces the display brightness of the foldable screen. When the DDIC driver executes the control instructions, it can implement relevant calls of the display light service through an API or a function provided by the framework layer, and control the display brightness of the foldable screen in combination with the ambient light information. For example, the display brightness of the backlight source of the foldable screen.

[0090] It should be understood that FIG. 3 is only an example of a system architecture diagram to which the display control method of the embodiments of the present application is applicable, and is not any limitation. In other embodiments, the electronic device can have more or fewer devices or modules than those in the structure shown in FIG. 3, or devices or modules for implementing the same functions can have other names, which are not limited by the embodiments of the present application.

[0091] The display control method of the embodiments of the present application will be described below taking the foldable screen of the electronic device as an example, which is implemented as a three-fold screen. Among them, the light sensing device represents the ambient light sensor described in the foregoing, which is used to detect ambient light information of the environment in which the electronic device is located. At least two light sensing devices of the electronic device are deployed on different display areas of the three-fold screen of the electronic device, and according to the posture change of the user using the electronic device, the processor can switch the light sensing devices to control the display brightness of the three-fold screen of the electronic device using the ambient light information detected by the corresponding light sensing devices, thereby meeting the dimming requirements in different postures. As shown in FIG. 4, the display control method can include the following steps:

[0092] S410: When the tri-fold screen is in its first orientation, the processor uses the ambient light information detected by the first of at least two light sensors to control the display brightness of the tri-fold screen.

[0093] S420: The processor determines that the tri-fold screen changes from a first posture to a second posture, and the second posture is associated with the second of at least two light sensors.

[0094] S420: When the tri-fold screen is in its second orientation, the processor uses the ambient light information detected by the second light sensor to control the display brightness of the tri-fold screen.

[0095] In this embodiment, the first posture and the second posture represent two postures of the tri-fold screen before and after a posture change. This posture change can refer to a change in the physical posture of the tri-fold screen, or it can refer to different display postures of the tri-fold screen relative to the user's viewing angle under the same physical posture. The various postures of the tri-fold screen can correspond one-to-one with its various display states. In different display states, the displayable area of ​​the tri-fold screen can be different, and the available light-sensing devices can also be different. The processor can control the display brightness of the tri-fold screen by switching the required light-sensing devices based on the actual posture changes and the correspondence between different postures and different display states.

[0096] To make it easier to understand, we will use examples below.

[0097] In this embodiment, the foldable screen of the electronic device can be displayed as a complete display area when fully unfolded. The user can fold the screen along one or more folding axes (or folding lines). The positions of the folding axes can be preset or arbitrarily selected by the user within the foldable screen. After the user folds the screen along the folding axes, the foldable screen can be divided into multiple display areas along the folding axes.

[0098] Taking a tri-fold screen as an example, in one example, as shown in Figure 5a, the folding axis of the electronic device may include folding axis 1 and folding axis 2. The foldable screen of the electronic device can be equally divided into three display areas along folding axis 1 and folding axis 2, denoted as area A, area B, and area C, respectively. The areas of area A, area B, and area C are equal or approximately equal. In another example, as shown in Figure 5b, the folding axis of the electronic device may include folding axis 3 and folding axis 4. The foldable screen of the electronic device can be unequally divided into three display areas along folding axis 3 and folding axis 4, denoted as area A, area B, and area C, respectively. The area of ​​area A is similar to the area of ​​area C, and the sum of the areas of area A and area C is approximately equal to the area of ​​area B.

[0099] It should be noted that in Figures 5a and 5b, areas A, B, or C can physically be the same screen or three screens. Alternatively, a combination of two areas from A, B, or C can be the same screen, with the remaining screen being another screen. This application does not limit this. In other embodiments, the foldable screen of the electronic device can also be a two-fold screen, a four-fold screen, or more folded screens. In different examples, the implementation method of dividing the foldable screen into several display areas can also be different, and this application does not limit this.

[0100] The following section uses the tri-fold screen shown in Figure 5a as an example to introduce the posture changes of the foldable screen of electronic devices and the changes of the light-sensing devices involved in the corresponding postures.

[0101] Taking the tri-fold screen shown in Figure 5a as an example, in one example, folding axis 1 supports folding the corresponding display area to the back, and folding axis 2 supports folding the corresponding display area to the front. The back (or rear) described here refers to the side of each display area of ​​the foldable screen facing away from the user, and the front refers to the side of each display area facing the user. In the embodiments of this application, it is generally assumed that the front of each display area has a display function. In specific implementations, it is not limited whether the back of each display area has a display function.

[0102] The folding methods supported by folding axis 1 can be described as follows: with area B fixed, rotate area A 0-180° away from area B; or with area A fixed, rotate area B 0-180° away from area A. The folding methods supported by folding axis 2 can be described as follows: with area B fixed, rotate area C 0-180° towards area B; or with area C fixed, rotate area B 0-180° towards area A. Using a top-down view from the top of the electronic device, as shown in Figure 6, dashed arrows indicate the screen rotation direction. When area A is fixed, rotation direction 1 indicates rotating area B away from area A. When area B is fixed, rotation direction 2 indicates rotating area A away from area B. When area B is fixed, rotation direction 3 indicates rotating area C towards area B. When area C is fixed, rotation direction 4 indicates rotating area B towards area C.

[0103] In another example, the folding methods supported by folding axis 1 and folding axis 2 can be interchanged. For example, folding axis 2 supports folding the corresponding display area to the back, while folding axis 1 supports folding the corresponding display area to the front. Accordingly, the folding method supported by folding axis 1 can be described as: with area B fixed, rotating area A 0-180° in the direction facing area B; or as: with area A fixed, rotating area B 0-180° in the direction facing area A. The folding method supported by folding axis 2 can be described as: with area B fixed, rotating area C 0-180° in the direction away from area B; or as: with area C fixed, rotating area B 0-180° in the direction away from area A. In this example, the folding methods supported by folding axis 1 and folding axis 2 are similar to those shown in Figure 6, and will not be described again here.

[0104] Based on the folding axis arrangement shown in Figure 6 and the folding methods supported by the folding axis, the three-fold screen of the electronic device can have multiple physical postures, including a fully unfolded posture, a fully folded posture, and at least one half-folded posture, as shown in Figures 7a-7d. Under different physical postures, the display state of the three-fold screen can be represented as display state 1, display state 2, display state 3, and display state 4, respectively. In different display states, the displayable area of ​​the three-fold screen is different, and the light-sensing devices used may also be different.

[0105] (1) Fully extended posture and display state 1:

[0106] In this embodiment of the application, as shown in the front view on the left side of Figure 7a, in the fully unfolded state, the displayable area of ​​the tri-fold screen includes areas A, B, and C, meaning that areas A, B, and C are displayed simultaneously. As shown in the rear view on the right side of Figure 7a, the back of the electronic device includes the back of area C, the back of area B, and the back of area A. Some components of the electronic device may be located in only one of the three display areas of the tri-fold screen. For example, the light sensor 1 is located in the upper left of area A, the front camera is located in the middle of the upper part of the screen in area A, the light sensor 2 is located in the upper right of area C, and the rear camera is located on the back of area C. Considering the folding method of the folding axis 1, components may not be provided on the back of areas A and B.

[0107] Display state 1 corresponds to the fully unfolded posture of the tri-fold screen; display state 1 can also be called G state. In display state 1, the light-sensing devices that the tri-fold screen can use can include light-sensing device 1 located in area A or light-sensing device 2 located in area C.

[0108] (2) Half-folded posture 1 and display status 2:

[0109] In this embodiment, based on the fully unfolded posture shown in Figure 7a, while keeping areas A and B fixed and different (areas A and B are not folded), area C is rotated 180° along the folding axis 2 towards the direction facing area B, so that the front of area B is in contact with the front of area C, which can be converted into a semi-folded posture. For ease of distinction, this semi-folded posture can be represented as semi-folded posture 1.

[0110] In this semi-folded posture, as shown in the front view on the left side of Figure 7b, the front of area B is obscured by the back of area C. The displayable area of ​​the tri-fold screen only includes area A, excluding areas B and C; that is, only area A is displayed. As shown in the rear view on the right side of Figure 7b, the back of the electronic device includes the back of area A and the back of area B. Similar to Figure 7a, the light sensor 1 is located at the upper left of area A, the front camera is located at the center of the top of the screen in area A, and the rear camera is located on the back of area C. No components may be placed on the back of areas A and B.

[0111] Display state 2 corresponds to the half-folded posture 1 of the tri-fold screen. Display state 2 can also be called N state. In display state 2, the light sensor that can be used by the tri-fold screen is light sensor 1 located in area A.

[0112] (3) Half-folded posture 2 and display status 3:

[0113] In this embodiment, based on the fully unfolded posture shown in Figure 7a, while keeping regions B and C fixed and different (regions B and C are not folded), region A is rotated 180° away from region B along the folding axis 1, so that the back of region A is in contact with the back of region B, thus converting it into another semi-folded posture. Alternatively, based on the semi-folded posture transformation shown in Figure 7b, it can also be converted into another semi-folded posture. For ease of distinction, this other semi-folded posture can be represented as semi-folded posture 2.

[0114] In the semi-folded posture 2, as shown in the front view on the left side of Figure 7c, the displayable area of ​​the tri-fold screen includes areas B and C, meaning that areas B and C can be displayed simultaneously. In the rear view on the right side of Figure 7c, the back of the electronic device includes the back of area C and the front of area A. Similar to Figure 7a, the light sensor 1 is located at the upper left of area A, the front camera is located at the center of the top of the screen in area A, the light sensor 2 is located at the upper right of area C, and the rear camera is located at the back of area C. No components may be placed on the back of areas A and B.

[0115] Display state 3 corresponds to the half-folded posture 2 of the tri-fold screen; display state 3 can also be called M state. In display state 3, the light sensor that can be used on the tri-fold screen is the light sensor 2 located in area C.

[0116] (4) Fully folded posture and display status 4:

[0117] In this embodiment, based on the fully unfolded posture shown in Figure 7a, while keeping area A fixed, area C is rotated 180° along folding axis 2 towards the direction facing area B, so that the front of area B is in contact with the front of area C. Then, area B is rotated 180° along folding axis 1 away from area A, so that the back of area A is in contact with the back of area B, thus converting it into a fully folded posture. Alternatively, based on the half-folded posture transformation shown in Figure 7b or Figure 7c, it can also be converted into a fully folded posture.

[0118] In its fully folded position, as shown in the front view on the left side of Figure 7d, the displayable area of ​​the tri-fold screen only includes area A; that is, only area A is displayed, while areas B and C are not. In the rear view on the right side of Figure 7d, the back of the electronic device includes the back of area C. Similar to Figure 7a, the light sensor 1 is located at the upper left of area A, the front camera is located at the center of the top of the screen in area A, and the rear camera is located on the back of area C. The backs of areas A and B may be left un-displayed. Since the front of area B and the front of area C are flush, the light sensor 2 located in area C is not displayed.

[0119] Display state 4 corresponds to the fully folded posture of the tri-fold screen; display state 4 can also be called F state. In display state 4, the light sensor that can be used on the tri-fold screen is light sensor 1 located in area A.

[0120] It is understood that Figures 7a-7d are merely illustrative examples of different display states of electronic devices, using the tri-fold mobile phone and the device form shown in Figure 5a as examples, and are not intended to limit the scope of the device. In other embodiments, if the electronic device is implemented in other product forms, the folding method of the foldable screen and the display state of the electronic device may also be different, which will not be elaborated here.

[0121] The different physical postures shown in Figures 7a-7d correspond to the dimming strategies shown in Table 1 below:

[0122] Table 1

[0123] Therefore, when implementing the display control method shown in Figure 4, if the posture change is involved and the light sensing device used before and after the posture change is different, the processor can switch the light sensing device according to the posture change, so as to use the ambient light information detected by the corresponding light sensing device to control the display brightness of the tri-fold screen.

[0124] For example, when the first posture and the second posture correspond to different physical postures of the tri-fold screen, the first photosensitive device can be a photosensitive device disposed in the first display area, and the second photosensitive device can be a photosensitive device disposed in the second display area. The display state associated with the first posture can be represented as either a first display state or a second display state. In both the first and second display states, the displayable area of ​​the tri-fold screen includes the first display area but excludes the second display area. The display state associated with the second posture can be represented as a third display state, in which the displayable area of ​​the tri-fold screen can include the second display area but exclude the first display area. Alternatively, the display state associated with the second posture can be represented as a fourth display state, in which the displayable area of ​​the tri-fold screen can include both the first and second display areas.

[0125] Taking Figures 7a-7d as an example, area A can be represented as the first display area, area B as the third display area, and area C as the second display area. Folding axis 1 can be represented as the first folding axis, and folding axis 2 as the second folding axis. The first display state, or F state, corresponds to the fully folded posture. In the first display state, the first and third display areas are folded backwards along the first folding axis, and the second and third display areas are folded forwards along the second folding axis. The displayable area of ​​the tri-fold screen does not include the third display area. The second display state, or N state, corresponds to half-folding posture 1 and is represented as the first half-folding posture. In the second display state, the second and third display areas are folded forwards along the second folding axis, while the first and third display areas are not folded. The displayable area of ​​the tri-fold screen does not include the third display area. The third display state, or M state, corresponds to half-folding posture 2 and is represented as the second half-folding posture. In the third display state, the first and third display areas are folded backwards along the first folding axis, while the second and third display areas are not folded. The displayable area of ​​the tri-fold screen also includes the third display area. The fourth display state, or G state, corresponds to the fully unfolded posture. In the fourth display state, the first and third display areas are not folded, the second and third display areas are not folded, and the displayable area of ​​the tri-fold screen also includes the third display area.

[0126] It should be understood that the above description is merely illustrative and not in any way limiting. In other embodiments, if the posture change involves different physical postures of the tri-fold screen, the first light sensor may also be a light sensor disposed in the second display area, and the second light sensor may also be a light sensor disposed in the first display area. Accordingly, the first posture may be associated with the third or fourth display state described above, and the second posture may be associated with the first or second display state described above.

[0127] In other words, in the above display control method, the processor can analyze whether the physical posture of the tri-fold screen has changed based on the sensor data detected by various sensors, and switch to using the light sensor associated with the current physical posture to detect ambient light information when different light sensors are used for different physical postures, so as to meet the different dimming requirements under different physical postures.

[0128] In reality, due to the individualized usage habits of users, such as the different positions of the electronic device's display screen relative to the user (e.g., standing, sitting, or lying down), and whether the electronic device is held diagonally upwards or downwards towards the user's face, or rotated, all these factors affect the recognition result of the electronic device's posture. In this embodiment, the sensor is used not only to detect whether the physical posture of the tri-fold screen changes, but also to detect whether the display posture of the tri-fold screen relative to the user's viewing angle changes under the same physical posture. The processor can decide whether to switch the light-sensing device based on the change in display posture, thereby meeting the dimming requirements of the electronic device under different display states as much as possible.

[0129] In this embodiment of the application, as shown in Figure 8a, the angle of the user's face when looking straight ahead can be predefined as a reference of 0 degrees, referred to as the eye-level viewing angle. When the user's head remains stationary while their eyes turn downwards, or when the user's head turns downwards, this is the user's top-down viewing angle. When the user's head remains stationary while their eyes turn upwards, or when the user's head turns upwards, this is the user's bottom-up viewing angle. Taking the user's eye-level viewing angle as an example, Figure 8b shows the attitude angles of the electronic device or the attitude angles relative to the user's viewing angle, including pitch, roll, and yaw. When implementing S420, the electronic device (or its processor) can determine whether the tri-fold screen represents a change in display posture relative to the user's viewing angle under the same physical posture.

[0130] Taking the different physical postures shown in Figures 7a-7d as examples, the dimming strategies involved in the changes in device posture angle can include the contents shown in Table 2 below:

[0131] Table 2

[0132] As shown in Figure 9, taking the display posture change of an electronic device (such as a fully folded mobile phone) relative to the user's viewing angle based on the pitch angle as an example, it can be predefined that when the electronic device is placed horizontally with the screen facing upwards, the pitch angle corresponds to 0 degrees; when the electronic device changes to a vertical position with the screen facing the user's face, the pitch angle corresponds to 90 degrees; and when the electronic device is placed horizontally with the screen facing downwards, the pitch angle corresponds to 180 degrees. It can be seen that during this display posture change process, the displayable area always includes area A. According to the strategy shown in Table 2, the light sensor 1 set on area A can be used to implement dimming control without switching the light sensor.

[0133] As shown in Figure 10, taking the display posture change of an electronic device (such as a mobile phone in a fully folded posture) relative to the user's viewing angle based on the flip angle as an example, in the fully folded posture, the displayable area of ​​the tri-fold screen only includes area A, where a light sensor 1 is installed. Conventional display postures can include portrait display postures. In the portrait display posture, the tri-fold screen can rotate clockwise based on the flip angle to a landscape display posture, and in the portrait display posture, it can rotate counterclockwise based on the flip angle to another landscape display posture. It can be seen that during this display posture change process, the displayable area always includes area A. According to the strategy shown in Table 2, dimming control can be implemented using the light sensor 1 installed on area A without switching the light sensor.

[0134] As shown in Figure 11, taking the display posture change of an electronic device (e.g., a mobile phone in a semi-folded posture 2) relative to the user's viewing angle based on the flip angle as an example, in the semi-folded posture 2, the displayable area of ​​the tri-fold screen includes area B and area C, with a light sensor 2 installed in area C. Conventional display postures can include portrait display postures. In the portrait display posture, the tri-fold screen can rotate clockwise based on the flip angle to a landscape display posture, and in the portrait display posture, it can rotate counterclockwise based on the flip angle to another landscape display posture. It can be seen that during this display posture change process, the displayable area always includes area C. According to the strategy shown in Table 2, dimming control can be implemented using the light sensor 2 installed in area C, without the need to switch the light sensor.

[0135] As shown in Figure 12, taking the display posture change of an electronic device (e.g., a mobile phone in a semi-folded posture 1) relative to the user's viewing angle based on the flip angle as an example, in the semi-folded posture 1, the displayable area of ​​the tri-fold screen includes area A, where a light sensor 1 is installed. Conventional display postures can include a portrait display posture. In the portrait display posture, the tri-fold screen can rotate clockwise based on the flip angle to a landscape display posture, and in the portrait display posture, it can rotate counterclockwise based on the flip angle to another landscape display posture. It can be seen that during this display posture change process, the displayable area always includes area A. According to the strategy shown in Table 2, dimming control can be implemented using the light sensor 1 installed on area A, without the need to switch the light sensor.

[0136] As shown in Figures 13a-13d, taking the display posture change of an electronic device (e.g., a fully unfolded mobile phone) relative to the user's viewing angle based on the flip angle as an example, in the fully unfolded posture, the displayable area of ​​the tri-fold screen includes areas A, B, and C. Area A and area C are equipped with light sensors 1. Conventional display postures can include a landscape display posture. In the landscape display posture, the tri-fold screen can rotate clockwise based on the flip angle to a portrait display posture, denoted as Portrait 1. In the landscape display posture or in the portrait 1 posture, it can rotate counterclockwise based on the flip angle to another portrait display posture, denoted as Portrait 2. Alternatively, in the portrait 1 posture, it can rotate clockwise based on the flip angle to the portrait 2 posture.

[0137] In landscape mode, the processor can control the display brightness of the tri-fold screen based on the ambient light information detected by either photosensitive device 1 or photosensitive device 2, according to the dimming strategy shown in Table 1.

[0138] When the tri-fold screen changes relative to the user's viewing angle based on the flip angle, in one implementation, the processor can keep the light sensor unchanged and continue to control the display brightness of the tri-fold screen based on the ambient light information detected by light sensor 1 or light sensor 2. As shown in Figure 13a, in both landscape and two portrait display orientations, the processor can control the display brightness of the tri-fold screen based on the light sensor detected by light sensor 1. Alternatively, as shown in Figure 13b, in both landscape and two portrait display orientations, the processor can control the display brightness of the tri-fold screen based on the light sensor detected by light sensor 2.

[0139] In another implementation, when the tri-fold screen changes its display posture relative to the user's viewing angle under the same physical posture, the processor can also switch the corresponding light sensor according to the strategy shown in Table 2, and use the ambient light information detected by the switched light sensor to control the display brightness of the tri-fold screen, so as to reduce the problem of inaccurate dimming caused by factors such as the user's hand blocking the light.

[0140] Taking a user's right hand as an example, as shown in Figure 13c, when the flip angle changes in the fully unfolded position, the first posture can be associated with the landscape display posture of the tri-fold screen in the fully unfolded position, and the first light sensor is light sensor 2 located in the second display area (area C). The posture of the vertical screen 1 can be represented as the first vertical display posture of the tri-fold screen, and the posture of the vertical screen 2 can be represented as the second vertical display posture of the tri-fold screen. The second posture can be associated with the first vertical display posture, and the second light sensor is light sensor 1 located in the first display area (area A). Therefore, after the tri-fold screen changes from the first posture to the second posture, the processor can use the ambient light information detected by light sensor 1 to control the display brightness of the tri-fold screen. Conversely, if the tri-fold screen changes from the second posture to the first posture, the processor can also switch light sensor 1 to light sensor 2 and use the ambient light information detected by light sensor 2 to control the display brightness of the tri-fold screen.

[0141] Therefore, switching the light sensor when the screen orientation changes between landscape and portrait can reduce the problem of dimming accuracy caused by the user's hand (e.g., right hand) obstructing the light sensor 2 when holding the electronic device. Subsequently, if the user holds the electronic device and changes the tri-fold screen from the first portrait orientation to the second portrait orientation, the dimming control in the second portrait orientation is less affected by the hand (e.g., right hand) obstruction. In this case, the light sensor does not need to be switched, and the ambient light information detected by the light sensor 1 located in the first display area (Area A) can continue to be used to control the display brightness of the tri-fold screen.

[0142] In other embodiments, some users have their left hand as their dominant hand. Based on this consideration, as shown in Figure 13d, when the flip angle changes in the fully unfolded position, the first posture can be associated with the landscape display posture of the tri-fold screen in the fully unfolded position, and the first light sensor is light sensor 1 located in the first display area (area A). The portrait posture 2 can be represented as the third portrait display posture of the tri-fold screen, and the posture of the portrait posture 1 can be represented as the fourth portrait display posture of the tri-fold screen. The second posture can be associated with the third portrait display posture, and the second light sensor is light sensor 2 located in the second display area (area C). Therefore, after the tri-fold screen changes from the first posture to the second posture, the processor can use the ambient light information detected by light sensor 2 to control the display brightness of the tri-fold screen. Conversely, if the tri-fold screen changes from the second posture to the first posture, the processor can also switch light sensor 2 to light sensor 1 and use the ambient light information detected by light sensor 1 to control the display brightness of the tri-fold screen.

[0143] Therefore, switching the light sensor when the screen orientation changes between landscape and portrait can reduce the problem of dimming accuracy caused by the user's hand (e.g., left hand) obstructing the light sensor 1 when holding the electronic device. Subsequently, if the user holds the electronic device and changes the tri-fold screen from the third portrait orientation to the fourth portrait orientation, the dimming control in the fourth portrait orientation is less affected by the hand (e.g., left hand) obstruction. Therefore, the light sensor does not need to be switched, and the ambient light information detected by the light sensor 2 located in the second display area (area C) can continue to be used to control the display brightness of the tri-fold screen.

[0144] When different physical orientations are involved, such as changing from M state to G state, the display area A is flipped from the back to the plane where areas B and C are located. The lighting environment of the light sensor 1 set in area A is not in the same plane as the final screen lighting environment. Therefore, if the light sensor 1 set in area A is directly used for dimming, there may be a jump, which will bring a poor user experience.

[0145] Therefore, in this embodiment of the application, when the tri-fold screen switches from M state to G state, the following strategy 1 or strategy 2 can be implemented according to the contents shown in Table 2:

[0146] Strategy 1: Switch the light sensor used from light sensor 2 to light sensor 1. The switch can be made after the ambient light in area A has stabilized, and conservative dimming can be used during this period. Stable ambient light in area A means that the ambient light intensity detected by light sensor 1 in area A remains within a relatively small illuminance range. Conservative dimming could mean, for example, not dimming the light.

[0147] Strategy 2: Do not switch the light sensor; continue using light sensor 2 set in area C. When the screen is detected to rotate from landscape to portrait mode (including portrait mode 1 or portrait mode 2), switch the light sensor used from light sensor 2 to light sensor 1 to reduce the impact of factors such as hand obstruction on dimming accuracy.

[0148] In the above scenario, if a user uses an electronic device to change the tri-fold screen from portrait to landscape orientation, the processor can switch the used light sensor from light sensor 1 to light sensor 2, as shown in Table 2. Each time the user rotates the electronic device, for example, changing from landscape to portrait or vice versa, the light sensor switching is triggered to reduce the impact of factors such as hand obstruction on dimming accuracy. Alternatively, if the user's dominant hand is right-handed and light sensor 1 is currently being used, the probability of light sensor 1 being obstructed is relatively low, and the light sensor will not be switched again during subsequent landscape / portrait orientation changes to ensure dimming stability. If the user's dominant hand is left-handed and light sensor 2 is currently being used, the probability of light sensor 2 being obstructed is relatively low, and the light sensor will not be switched again during subsequent landscape / portrait orientation changes to ensure dimming stability.

[0149] Taking a user's right hand as an example, as shown in Figure 13e, when the tri-fold screen is in state M, the display area includes areas B and C, and the available light sensor is light sensor 2 located in area C. When the tri-fold screen changes from state M to state G, the available light sensors include light sensor 1 located in area A and light sensor 2 located in area C. To reduce dimming jumps, the light sensor can be temporarily not switched, and light sensor 1 can continue to detect ambient light information to achieve dimming control. When the tri-fold screen changes from a horizontal display posture to a vertical display posture 1 or a vertical display posture 2 in a fully unfolded position, to reduce the impact of factors such as the user's right hand blocking the view, light sensor 1 can be switched accordingly, and the display brightness of the tri-fold screen can be controlled using the ambient light information detected by light sensor 1. Currently, light sensor 1 is being used, and the probability of light sensor 1 being blocked is relatively low. The light sensor will not be switched again when switching between horizontal and vertical postures to ensure dimming stability.

[0150] Therefore, the above description, in conjunction with Figures 5a-13e, introduces the posture change scenarios and corresponding dimming strategies involved in the display control method of this application. This method can flexibly switch the light-sensing devices used according to the posture changes of the foldable screen of the electronic device, so as to meet the different dimming requirements of different display states of the electronic device and ensure the user's visual experience.
