DETAILED DESCRIPTION

[0096] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0097] With the development of flexible display technology, flexible displays such as curved screens and foldable screens have been widely used in electronic devices such as mobile phones, so that electronic devices have more diverse display forms and enrich the user experience. In the use of the foldable screen, it is necessary to detect the opening and closing state of the screen, adjust the display state of the inner and outer screens according to whether the screen is folded or unfolded, and realize different display functions according to the different unfolding angles. In the related art, an acceleration gyro sensor (a+G-sensor) is usually set behind the screen to judge the opening and closing angle by the initial position and acceleration of the screen, or a digital Hall sensor is set to detect the position to judge the opening and closing state. The two sensors can also be used in combination to judge the opening and closing state of the foldable screen.

[0098] However, the above detection method detects the opening and closing status of the screen. Due to the resonance, temperature drift, and easy integration error of the acceleration and gyroscope sensor, the digital Hall sensor has high hardware cost and is limited by the structure. There are problems such as large detection error, low detection reliability, large space occupied by the detection device and high cost.

[0099] Based on this, the exemplary embodiment of the present disclosure provides a method for detecting the opening and closing state of a screen, wherein the sensor on the first screen determines the detection information used to characterize the distance between the sensor and the second screen, and the opening and closing state information between the first screen and the second screen can be determined according to the detection information, thereby realizing corresponding control of the screen display according to the opening and closing state information. The acquisition of the detection information is completed by one or more sensors on the first screen, thereby avoiding the problem of large occupied space and high cost caused by adding detection devices.

[0100] In an exemplary embodiment, a method for detecting the opening and closing state of a screen is provided. First, the structure of the screen is introduced. Figure 2 As shown, the screen includes a first screen body 10 and a second screen body 20, and the first screen body 10 and the second screen body 20 can be relatively folded and unfolded around a rotation axis 30. Figure 1 As shown, the screen opening and closing state detection method includes:

[0101] S100: Determine one or more detection information through one or more sensors on the first screen, where the detection information is used to characterize the distance from each sensor to the second screen.

[0102] In step S100, the screen is as follows Figure 2 As shown, the corresponding detection information can be determined by one or more sensors 40 on the first screen 10, such as Figure 3 , Fig. 9 , Fig.13As shown, the sensor 40 may be, for example, a specific absorption rate sensor 42, a distance sensor 41, a camera 43, etc., and the detection information is used to characterize the distance between each sensor 40 and the second screen 20. The distance between the sensor 40 and the second screen 20 may be, for example, the shortest distance between the sensor 40 and the second screen 20, or the distance between the sensor 40 and the second screen 20 along a specific direction. It can be understood that the acquired detection information is the distance from the screen where the sensor 40 is located to another screen. When multiple sensors 40 are provided and located on different screens, for each sensor 40, the screen where the sensor 40 is located is the first screen 10, and the other screen outside the screen where the sensor 40 is located is the second screen 20, that is, for different sensors 40, the first screen 10 may be the same or different.

[0103] S200: Determine the opening and closing state information between the first screen and the second screen based on one or more detection information.

[0104] In step S200, based on the detection information, the opening and closing state information between the first screen body 10 and the second screen body 20 is determined, that is, the opening and closing state information between the first screen body 10 and the second screen body 20 is obtained according to the detection information used to characterize the distance between the sensor 40 and the second screen body 20. The opening and closing state information can be, for example, an angle value, or an angle level representing a range of different angle values, and the screen display can be controlled accordingly according to the opening and closing state information such as the angle value or the angle level.

[0105] When there are multiple sensors 40, the opening and closing state information can be determined for each of the multiple detection information obtained by the multiple sensors 40, and the multiple opening and closing state information can be integrated by, for example, taking an average value to obtain more accurate opening and closing state information.

[0106] In this embodiment, the sensor 40 on the first screen 10 determines the detection information used to characterize the distance between the sensor 40 and the second screen 20, and the opening and closing state information between the first screen 10 and the second screen 20 can be determined according to the detection information, so as to realize the corresponding control of the screen display according to the opening and closing state information. The acquisition of detection information is completed by one or more sensors 40 on the first screen 10, avoiding the problem of large occupied space and high cost caused by adding detection devices. In addition, the final opening and closing state information is determined based on multiple detection information, which reduces the detection error rate and improves the detection reliability.

[0107] In some embodiments, Figure 3As shown, the one or more sensors 40 include a distance sensor 41, which can be, for example, an ultrasonic sensor, an infrared sensor, a laser sensor, etc., which are arranged on the first screen 10. The ultrasonic sensor can also be used to turn off the screen display during a call, and the laser sensor can also be used to obtain the distance information of the object being photographed when taking pictures. Figure 4 As shown, one or more detection information is determined by one or more sensors 40 on the first screen 10, including:

[0108] S330. Determine detection information corresponding to the distance sensor based on the first detection signal and the second detection signal, where the first detection signal is a detection signal sent by the distance sensor along a preset direction, and the second detection signal is a detection signal after the first detection signal received by the distance sensor is reflected by the second screen.

[0109] In step S330, based on the first detection signal emitted by the distance sensor 41 to the second screen 20 and the second detection signal received by the distance sensor 41 after being reflected by the second screen 20, detection information characterizing the distance from the distance sensor 41 to the second screen 20 can be determined.

[0110] For example, reference Figure 4 As shown, before determining the detection signal corresponding to the distance sensor 41 based on the first detection signal and the second detection signal, the step of determining one or more detection information by the distance sensor 41 may also include:

[0111] S310, controlling the distance sensor to send a first detection signal along a preset direction.

[0112] In step S310, the distance sensor 41 is controlled to send a first detection signal along a preset direction. The preset direction is set at a certain angle with the first screen body 10, and the first detection signal can be reflected when it contacts other objects.

[0113] S320: Acquire a second detection signal received by the distance sensor after being reflected by the second screen.

[0114] In step S320 , the first detection signal is reflected by the second screen body 20 after reaching the second screen body 20 , and the first detection signal reflected by the second screen body 20 forms a second detection signal, which is received by the distance sensor 41 .

[0115] In this embodiment, when the sensor 40 includes a distance sensor 41 for detecting the distance, the detection information corresponding to the distance sensor 41 can be determined according to the first detection signal and the second detection signal, thereby realizing the determination of the detection information and providing a basis for determining the opening and closing state information, so that the corresponding control of the screen display can be realized according to the opening and closing state information. The distance sensor 41 is a sensor 40 for realizing other functions on the first screen body 10, which does not lead to an increase in occupied space and cost, and the distance sensor 41 has high detection accuracy, reduces the detection error rate, and improves the detection reliability.

[0116] In some embodiments, reference Figure 5 As shown, based on the first detection signal and the second detection signal, the detection information corresponding to the distance sensor 41 is determined, including:

[0117] S331 , determining a time difference between when the distance sensor sends a first detection signal and when it receives a second detection signal.

[0118] In step S331, the time difference between the distance sensor 41 sending the first detection signal and receiving the second detection signal is first determined. The time difference is the sum of the time it takes for the first detection signal to reach the second screen 20 after being sent and the time it takes for the second detection signal formed after the first detection signal is reflected by the second screen 20 to reach the distance sensor 41.

[0119] S332. Determine detection information based on the time difference.

[0120] In step S332, after determining the time difference, for example, the obtained time difference can be directly used as detection information, and the transmission distance of the detection signal can be determined based on the time difference and the transmission speed of the detection signal, and the transmission distance or the distance level of the transmission distance can be used as detection information, thereby determining the detection information used to characterize the distance from the sensor 40 to the second screen 20.

[0121] In this embodiment, according to the time difference between the distance sensor 41 sending the first detection signal and receiving the second detection signal, the time length from the detection signal being sent by the sensor 40 to being received by the sensor 40 after being sent can be obtained, and the detection information used to characterize the distance from the sensor 40 to the second screen 20 can be determined according to the known information such as the time difference and the transmission speed of the detection signal, that is, the detection information is determined by the first detection signal and the second detection signal, which provides a basis for determining the opening and closing state information, so that the corresponding control of the screen display can be realized according to the opening and closing state information. The distance sensor 41 has high accuracy in obtaining the time difference, reduces the detection error rate, and improves the detection reliability.

[0122] In some embodiments, the first detection signal includes one of an ultrasonic signal, an infrared signal, a laser signal, or a combination of at least two of them.

[0123] Among them, when the first detection signal is an ultrasonic signal, the distance sensor 41 can be, for example, an ultrasonic sensor such as a mobile phone microphone, which detects the distance between the object to be measured and the ultrasonic sensor by sending and receiving ultrasonic signals. When the first detection signal is an infrared signal, the distance sensor 41 can be, for example, an infrared sensor, which can detect the distance between the object to be measured and the infrared sensor by sending and receiving infrared signals. When the first detection signal is a laser signal, the distance sensor 41 can be, for example, a time of flight (TOF) sensor, which can detect the distance between the object to be measured and the TOF sensor by sending and receiving laser signals.

[0124] In this embodiment, the first detection signal includes one or a combination of at least two of an ultrasonic signal, an infrared signal, and a laser signal sent by the distance sensor 41. The ultrasonic signal, the infrared signal, and the laser signal can all be reflected by the second screen 20, and the signal transmission speed after reflection is basically the same as that before reflection, and can all be used as the first detection signal to determine the detection information. Ultrasonic signals, infrared signals, and laser signals have strong anti-interference capabilities, which reduces the detection error rate and improves the detection reliability. The distance sensors 41 that can send ultrasonic signals, infrared signals, and laser signals are all conventional devices on the screen, avoiding the increase in occupied space and cost caused by adding other detection devices.

[0125] As mentioned above, the detection information may be the time difference between the distance sensor 41 sending the first detection signal and receiving the second detection signal, the signal transmission distance or distance level determined according to the time difference, etc. In some embodiments, the determined time difference is directly used as the detection information. Figure 6 As shown, based on one or more detection information, determining the opening and closing state information between the first screen body 10 and the second screen body 20 includes:

[0126] S401. Determine first angle information corresponding to the time difference according to the time difference and first preset configuration information, where the first preset configuration information is used to characterize a correspondence between the time difference and the angle information.

[0127] In step S401, based on the time difference between the distance sensor 41 sending the first detection signal and receiving the second detection signal, and the first preset configuration information used to characterize the correspondence between the time difference and the angle information, the first angle information corresponding to the time difference can be determined, and the first angle information can be, for example, an angle value. The first preset configuration information can be, for example, in the form of a table, a mapping, a formula, etc., and the first preset configuration information can be obtained by, for example, analyzing experimental data measured experimentally. Exemplarily, the angle information corresponding to the 1S time difference in the first preset configuration information is 30°, then when the time difference is 1S, it can be determined that the first angle information corresponding to the time difference is 30°.

[0128] S402: Determine the opening and closing state information between the first screen body and the second screen body according to the first angle information.

[0129] In step S402, after determining the first angle information according to the time difference and the first preset configuration information, the opening and closing state information between the first screen 10 and the second screen 20 is determined according to the first angle information. For example, the angle value of the first angle information can be directly determined as the opening and closing state information, and the angle level to which the angle value belongs can also be determined according to the angle value of the first angle information, and the angle level can be used as the opening and closing state information.

[0130] In this embodiment, based on the time difference between the distance sensor 41 sending the first detection signal and receiving the second detection signal, and the first preset configuration information used to characterize the correspondence between the time difference and the angle information, the first angle information corresponding to the time difference can be determined, and the opening and closing state information can be determined based on the first angle information, thereby realizing the conversion between the detection information and the opening and closing state information, so that the corresponding control of the screen display can be realized according to the opening and closing state information.

[0131] In other embodiments, the determined time difference is also directly used as the detection information, referring to Figure 7 As shown, based on one or more detection information, determining the opening and closing state information between the first screen body 10 and the second screen body 20 includes:

[0132] S411. Determine a first distance between the distance sensor and the second screen in a preset direction according to the time difference.

[0133] In step S411 , a first distance between the distance sensor 41 and the second screen 20 in a preset direction is determined according to a time difference between the distance sensor 41 sending a first detection signal and receiving a second detection signal.

The second angle information can be, for example, an angle value. The second preset configuration information can be, for example, in the form of a table, a mapping, a formula, etc. The second preset configuration information can be obtained by, for example, analyzing experimental data measured experimentally. Exemplarily, the angle information corresponding to the first distance of 10 cm in the second preset configuration information is 30°. When the first distance is 10 cm, it can be determined that the second angle information corresponding to the first distance is 30°.

After the first distance is determined, the first distance, the preset second distance and the preset angle are all determined values, that is, the lengths of two sides of the triangle and the angle of an included angle are determined, and the lengths of other sides of the triangle and the angles of other angles can be determined, so the opening and closing angle between the first screen body 10 and the second screen body 20 can be determined.

When the third distance is 10 cm, it can be determined that the third angle information corresponding to the third distance is 30°.

[0159] S602: Determine the opening and closing state information between the first screen body and the second screen body according to the third angle information;

[0160] In step S602, after determining the third angle information according to the third distance and the third preset configuration information, the opening and closing state information between the first screen 10 and the second screen 20 is determined according to the third angle information. For example, the angle value of the third angle information can be directly determined as the opening and closing state information, and the angle level to which the angle value belongs can be determined according to the angle value of the third angle information, and the angle level can be used as the opening and closing state information.

[0168] S720: Determine a fifth distance between the camera and the second screen in a preset direction according to distance information in the image information captured by the camera.

[0169] In step S720, the distance information may be the distance between the camera 43 and the object to be photographed, and when the foldable screen is folded, the distance information changes according to the distance between the camera 43 and the second screen body 20. Since the distance information changes according to the distance between the camera 43 and the second screen body 20, a fifth distance corresponding to the distance information may be determined according to the acquired distance information.

[0171] In step S730, after determining the third distance between the specific absorption rate sensor 42 and the second screen body 20, the detection information characterizing the distance from the specific absorption rate sensor 42 to the second screen body 20 is determined. For example, the obtained fifth distance can be directly used as the detection information, and the distance level of the fifth distance can also be used as the detection information.

[0172] For example, reference Fig.14 As shown, before determining the fifth distance between the camera and the second screen in the preset direction according to the distance information in the image information captured by the camera, the step of determining one or more detection information by the camera 43 may also include:

[0174] As mentioned above, the detection information may be the fifth distance or the distance level of the fifth distance determined according to the distance information in the image information captured by the camera 43. In some embodiments, the determined fifth distance is directly used as the detection information.

Exemplarily, the angle information corresponding to the fifth distance of 10 cm in the fourth preset configuration information is 30°. Then, when the fifth distance is 10 cm, it can be determined that the fourth angle information corresponding to the fifth distance is 30°.

[0177] S802: Determine the opening and closing state information between the first screen body and the second screen body according to the fourth angle information.

[0178] In step S802, after determining the fourth angle information according to the fifth distance and the fourth preset configuration information, the opening and closing state information between the first screen 10 and the second screen 20 is determined according to the fourth angle information. For example, the angle value of the fourth angle information can be directly determined as the opening and closing state information, and the angle level to which the angle value belongs can be determined according to the angle value of the fourth angle information, and the angle level can be used as the opening and closing state information.

[0180] In some other embodiments, the determined fifth distance is also directly used as the detection information, referring to Fig.16 As shown, based on one or more detection information, determining the opening and closing state information between the first screen body 10 and the second screen body 20 includes:

[0186] In some embodiments, the camera 43 is an AON camera.

[0187] Among them, the AON (Always On) camera is a front camera in full-time working state. Its main function is to perceive the environment, visually monitor user behavior, infer user intentions, and decide the status of the mobile phone. It can recognize the user's gaze, gestures, etc. to maintain screen brightness, control display rotation, etc. The AON camera can determine the distance between the AON camera and the second screen 20 through the distance information in the shooting information.

[0188] In some embodiments, reference Fig.17As shown, before determining the opening and closing state information between the first screen body 10 and the second screen body 20 based on one or more detection information, the screen opening and closing state detection method further includes:

[0189] S910, determining whether there is an obstacle between the first screen and the second screen;

[0190] S920: When it is determined that there is no obstacle between the first screen and the second screen, determine the opening and closing state information between the first screen and the second screen based on one or more detection information.

[0191] In step S910 to step S920, when there are other obstacles such as the palm of the user between the first screen body 10 and the second screen body 20, the distance represented by the detection information may be the distance between the sensor 40 and the obstacle. At this time, if the opening and closing state information is determined based on the detection information, the opening and closing state information will not reflect the actual opening and closing state between the first screen body 10 and the second screen body 20. It is necessary to first determine whether there is an obstacle between the first screen body 10 and the second screen body 20. When it is determined that there is no obstacle between the first screen body 10 and the second screen body 20, the opening and closing state information between the first screen body 10 and the second screen body 20 is determined based on the detection information according to the above method. When it is determined that there is an obstacle between the first screen body 10 and the second screen body 20, the detection information at this time can be invalidated or the detection information can be obtained again when there is no obstacle between the first screen body 10 and the second screen body 20.

[0192] In this embodiment, it is first determined whether there is an obstacle between the first screen body 10 and the second screen body 20. When it is determined that there is no obstacle between the first screen body 10 and the second screen body 20, the opening and closing state information between the first screen body 10 and the second screen body 20 is determined based on the detection information. This can ensure that the detection information truly represents the distance between the sensor 40 and the second screen body 20, thereby ensuring the accuracy of the opening and closing state information, avoiding interference of the obstacles between the first screen body 10 and the second screen body 20 with the screen opening and closing state detection, and improving the user experience.

[0193] In some embodiments, one or more sensors 40 include a specific absorption rate sensor 42, and determining whether there is an obstacle between the first screen 10 and the second screen 20 includes: determining whether there is an obstacle between the first screen 10 and the second screen 20 based on capacitance information detected by the specific absorption rate sensor 42.

[0194] Among them, the sensor 40 includes a specific absorption rate sensor 42, which can obtain capacitance information detected by the specific absorption rate sensor 42. The specific absorption rate sensor 42 can generate different capacitance information for the human body and different materials such as metal and glass. Therefore, it can be determined whether there is an obstacle between the first screen body 10 and the second screen body 20 according to the difference in capacitance information. For example, when the detected capacitance information represents that the material of the object to be detected is the material of the second screen body 20, it can be determined that there is no obstacle between the first screen body 10 and the second screen body 20. When the detected capacitance information represents that the material of the object to be detected is different from the material of the second screen body 20, it can be determined that there is an obstacle between the first screen body 10 and the second screen body 20.

[0195] In this embodiment, based on the capacitance information detected by the specific absorption rate sensor 42, it is possible to determine whether there is an obstacle between the first screen body 10 and the second screen body 20, thereby ensuring that the detection information truly represents the distance between the sensor 40 and the second screen body 20, thereby ensuring the accuracy of the opening and closing state information, avoiding interference with the screen opening and closing state detection caused by obstacles between the first screen body 10 and the second screen body 20, and improving the user experience.

[0196] In other embodiments, one or more sensors 40 include a camera 43, and determining whether there is an obstacle between the first screen 10 and the second screen 20 includes: determining whether there is an obstacle between the first screen 10 and the second screen 20 based on image information captured by the camera 43.

[0197] Among them, the sensor 40 includes a camera 43, which can obtain image information captured by the camera 43, and the camera 43 can generate different image information for the human body and other objects. Therefore, it can be determined whether there is an obstacle between the first screen 10 and the second screen 20 according to the different image information. For example, when the detected image information represents that the object to be detected is the second screen 20, it can be determined that there is no obstacle between the first screen 10 and the second screen 20. When the detected image information represents that the object to be detected is not the second screen 20, it can be determined that there is an obstacle between the first screen 10 and the second screen 20.

[0198] In this embodiment, based on the image information captured by the camera 43, it is possible to determine whether there is an obstacle between the first screen body 10 and the second screen body 20, thereby ensuring that the detection information truly represents the distance between the camera 43 and the second screen body 20, thereby ensuring the accuracy of the opening and closing state information, avoiding interference of obstacles between the first screen body 10 and the second screen body 20 with the screen opening and closing state detection, and improving the user experience.

When it is determined that there is no obstacle between the first screen 10 and the second screen 20, the opening and closing state information between the first screen 10 and the second screen 20 is obtained based on the detection information, which can ensure that the detection information truly represents the distance between the sensor 40 and the second screen 20, thereby ensuring the accuracy of the opening and closing state information, and avoiding interference of obstacles between the first screen 10 and the second screen 20 on the detection of the opening and closing state of the screen. The first distance between the distance sensor 41 and the second screen 20 in a preset direction is determined based on the time difference between the distance sensor 41 sending the first detection signal and receiving the second detection signal, and the corresponding opening and closing angle can be determined based on the first distance, the preset second distance and the preset angle, and the opening and closing status information is determined based on the opening and closing angle, thereby realizing the conversion between the detection information and the opening and closing status information, so that the corresponding control of the screen display can be realized according to the opening and closing status information.

[0210] In this embodiment, the detection information used to characterize the distance between the sensor 40 and the second screen 20 is determined by the first determination module 50, and the opening and closing state information between the first screen 10 and the second screen 20 is determined by the second determination module 60 according to the detection information, so as to realize the corresponding control of the screen display according to the opening and closing state information. The determination of the detection information is completed by one or more sensors 40 on the first screen 10, thereby avoiding the problem of large occupied space and high cost caused by adding detection devices. In addition, the final opening and closing state information is determined according to multiple detection information, which reduces the detection error rate and improves the detection reliability.
