Based on the method provided by the embodiment of the application, the brightness of the electronic equipment for controlling the lighting device changes along with the change of the sum of the included angle between the first screen and the second screen and the included angle between the fourth screen and the first screen, the operation is simple and convenient, the lighting brightness can be adjusted through blind operation, a user does not need to perform a complicated operation process on the screen, the lighting brightness can be gradually increased along with the operation of the user, the phenomenon that light is too dazzling when the lighting device is turned on is avoided, the eyesight of the user can be protected, and therefore the user experience can be improved.

In one possible implementation, the illumination device includes at least one of a light emitting diode, LED, a backlight of a folded screen, and a backlight of a third screen, the third screen being different from the first screen or the second screen. In this way, the kind of the lighting device to be turned on can be determined according to different situations. For example, the electronic device may determine the type of the lighting device to turn on according to the power remaining condition. Alternatively, the user may determine the kind of the lighting device to be turned on by blind operations such as folding or unfolding the folding screen.

In one possible implementation, in response to the first operation being preceded, the method further comprises: and determining that the illumination intensity of the position of the electronic equipment is less than or equal to a preset illumination intensity threshold value. In this way, the electronic device may perform the above-described processing when the ambient light intensity is insufficient, e.g., the electronic device may slowly illuminate the screen and/or gradually increase the brightness of the LEDs, protect the user's eyesight, and meet the user's lighting needs.

In a possible implementation manner, receiving the second operation of the user specifically includes: and receiving a second operation of the user within a first preset time period.

In a possible implementation manner, the first preset time period is a time period set according to an alarm clock, or the first preset time period is determined according to a sleep time of a user, or the first preset time period is determined according to a use habit of the user using the folding screen.

In a possible implementation manner, the second operation is used to unfold or fold the folding screen, and specifically includes: and the second operation is used for unfolding or folding the included angle between the first screen and the second screen to any included angle within a preset included angle range and keeping the included angle for a first preset time. It will be appreciated that when a user wishes to normally use a folding screen handset, the folding screen is typically opened to a maximum angle (e.g., 180 degrees), whereas when the user unfolds or folds the folding screen to within a preset angle range and maintains the configuration (e.g., the user opens the folding screen to 30 degrees and maintains the configuration), there is a high probability that the user wants the handset to be illuminated. Therefore, after the mobile phone detects that the user unfolds or folds the folding screen to the preset angle range and keeps the shape, the brightness of the lighting device can be controlled to be changed along with the change of the included angle between the first screen and the second screen, and the lighting requirement of the user is met.

For example, the first preset rule may be to flash alternately in at least two colors, for example, in red and green. Or the first preset rule may be that the angle between the first screen and the second screen is changed, for example, when the angle between the first screen and the second screen is 10 °, the lighting device is red, when the angle between the first screen and the second screen is 20 °, the lighting device is orange, and so on. Therefore, when the user is in scenes such as a concert or a party, the color of the lighting device can be controlled to change according to a preset rule, and the use experience of the user is improved.

In one possible implementation, controlling the lighting device to change the brightness as the angle between the first screen and the second screen changes includes: and controlling the lighting device to change the brightness along with the change of the included angle of the first screen and the second screen in a third preset time period.

In one possible implementation, the method further includes: and after a third preset time period, controlling the brightness of the lighting device to be unchanged along with the increase or decrease of the included angle between the first screen and the second screen. That is to say, in the third preset time period, the user can adjust the brightness intensity of the lighting device by adjusting the included angle between the first screen and the second screen. After the third preset time period, the brightness of the lighting device is unchanged, and at the moment, the user can readjust the included angle between the first screen and the second screen to find the holding mode and angle which the user likes.

In a possible implementation manner, the third preset time period is preset by the user, or the third preset time period is determined according to the use habit of the user using the folding screen.

The gyro sensor 480B may be used to determine the motion pose of the electronic device 100. In some embodiments, the angular velocity of the electronic device 100 about three axes (i.e., the x, y, and z axes) may be determined by the gyroscope sensor 480B. The gyro sensor 480B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 480B detects a shake angle of the electronic device 100, calculates a distance to be compensated for by the lens module according to the shake angle, and allows the lens to counteract the shake of the electronic device 100 through a reverse movement, thereby achieving anti-shake. The gyroscope sensor 480B can also be used for navigation and body sensing game scenes. In the embodiment of the present application, the display screen 494 of the electronic device 100 may be folded to form a plurality of screens. A gyro sensor 480B may be included in each screen for measuring the orientation (i.e., the directional vector of the orientation) of the corresponding screen. The electronic device 100 may determine the included angle between adjacent screens according to the measured angle change of the orientation of each screen.

It should be noted that in the embodiment of the present application, the foldable screen (such as the display screen 494 described above) of the electronic device 100 may be folded to form a plurality of screens. A gyro sensor (e.g., gyro sensor 480B described above) may be included in each screen for measuring the orientation (i.e., the directional vector of the orientation) of the corresponding screen. For example, in conjunction with FIG. 2A, the display screen 494 of the electronic device 100 may be folded to form an A-screen and a B-screen, each of which may include a gyroscope sensor 480B therein for measuring the orientation of the A-screen and the B-screen, respectively. The electronic device 100 may determine the included angle between adjacent screens according to the measured angle change of the orientation of each screen.

Illustratively, the folded screen of the electronic device 100 may be folded to form an A-screen and a B-screen as shown in FIG. 5A. A gyroscope sensor A is arranged in the screen A, and a gyroscope sensor B is arranged on the screen B. Here, the present embodiment describes a principle that the gyro sensor a measures the orientation of the a screen (i.e., the directional vector of the orientation), the gyro sensor B measures the orientation of the B screen (i.e., the directional vector of the orientation), and a principle that the electronic apparatus 100 calculates the angle α between the a screen and the B screen based on the orientation of the a screen and the orientation of the B screen.

Wherein the coordinate system of the gyro sensor is a geographical coordinate system. As shown in fig. 5B, the origin O of the geographic coordinate system is located at the point where the vehicle (i.e., the device containing the gyro sensor, such as the electronic device 100) is located, the x-axis points east (E) along the local latitudes, the y-axis points north (N) along the local meridian, and the z-axis points upward along the local geographic vertical line, and forms a right-hand orthogonal coordinate system with the x-axis and the y-axis. The plane formed by the x axis and the y axis is the local horizontal plane, and the plane formed by the y axis and the z axis is the local meridian plane. Thus, it can be understood that the coordinate system of the gyro sensor is: the gyroscope sensor is used as an origin O, the east direction along the local latitude line is used as an x axis, the north direction along the local meridian line is used as a y axis, and the upward direction along the local geographical vertical line (namely the opposite direction of the geographical vertical line) is used as a z axis.

The electronic device can measure and obtain the direction vector of the orientation of each screen in the coordinate system of the gyro sensor arranged in the electronic device by using the gyro sensor arranged in each screen. For example, referring to the side view of the electronic device as shown in fig. 5A, the directional vector of the orientation of the a-screen measured by the electronic device in the coordinate system of gyro sensor a is vector z1, and the directional vector of the orientation of the B-screen in the coordinate system of gyro sensor B is vector z 2. The electronic device utilizes equation (1):

the angle θ between vector z1 and vector z2 can be calculated.

As can be seen from fig. 5A, since the vector z1 is perpendicular to the a screen and the vector z2 is perpendicular to the B screen, the angle α between the a screen and the B screen can be obtained as 180 ° - θ. That is, the electronic device can determine the angle α between the a screen and the B screen according to the measured direction vector of the a screen in the coordinate system of the gyro sensor a (i.e., vector z1) and the direction vector of the B screen in the coordinate system of the gyro sensor B (i.e., vector z 2).

It should be noted that although the positions of the gyro sensors disposed in the a-screen and the B-screen do not overlap, that is, the origins of the coordinate systems of the gyro sensors disposed in the a-screen and the B-plane do not overlap, the x-axis, the y-axis, and the z-axis of the two coordinate systems are parallel, so that the coordinate systems of the gyro sensors disposed in the a-screen and the B-screen can be considered to be parallel. Thus, although the vector z1 and the vector z2 are not in the same coordinate system, the angle θ between the vector z1 and the vector z2 can be calculated by the above equation (1) because the axes of the two coordinate systems are parallel.

In some embodiments, the angle α between the a screen and the B screen can also be measured by one or more other sensors. For example, one acceleration sensor may be provided in each of the folding screens. The electronic device 100 (e.g., the processor 410) may measure the motion acceleration of each screen as it is rotated using the acceleration sensor; and then calculating the rotation angle of one screen relative to the other screen according to the measured motion acceleration, namely the included angle alpha between the screen A and the screen B.

In other embodiments, the gyro sensor may be a virtual gyro sensor formed by a plurality of other sensors in cooperation. The virtual gyroscope sensor can be used for calculating the included angle between adjacent screens of the folding screen, namely the included angle alpha between the screen A and the screen B.

And then according to the opening and closing state of the leather sheath or the opening and closing state of the flip cover, the automatic unlocking of the flip cover is set.

The acceleration sensor 480E may detect the magnitude of acceleration of the electronic device 100 in various directions (typically three axes). The magnitude and direction of gravity can be detected when the electronic device 100 is stationary. The method can also be used for recognizing the posture of the electronic equipment, and is applied to horizontal and vertical screen switching, pedometers and other applications. It should be noted that in the embodiment of the present application, the display screen 494 of the electronic device 100 may be folded to form a plurality of screens. An acceleration sensor 480E may be included in each screen for measuring the orientation (i.e., the directional vector of the orientation) of the corresponding screen.

The electronic device 100 emits infrared light to the outside through the light emitting diode. The electronic device 100 detects infrared reflected light from nearby objects using a photodiode. When sufficient reflected light is detected, it can be determined that there is an object near the electronic device 100. When insufficient reflected light is detected, the electronic device 100 may determine that there are no objects near the electronic device 100. The electronic device 100 can utilize the proximity sensor 480G to detect that the user holds the electronic device 100 close to the ear for talking, so as to automatically turn off the screen to save power.

In some embodiments, the electronic device 100 implements a temperature processing strategy using the temperature detected by the temperature sensor 480J. For example, when the temperature reported by the temperature sensor 480J exceeds a threshold, the electronic device 100 performs a reduction in performance of a processor located near the temperature sensor 480J, so as to reduce power consumption and implement thermal protection. In other embodiments, electronic device 100 heats battery 442 when the temperature is below another threshold to avoid an abnormal shutdown of electronic device 100 due to low temperatures.

The methods in the following embodiments may be implemented in the electronic device 100 having the above-described hardware structure.

For the sake of understanding, the folded screen illumination method provided by the embodiments of the present application is specifically described below with reference to the accompanying drawings.

As shown in fig. 6, an embodiment of the present application provides a method for illuminating a foldable screen, where an electronic device is a mobile phone, a foldable screen of the mobile phone is a folded-in foldable screen, and the folded-in foldable screen is described as an example, where the folded-in foldable screen is foldable to form a first screen and a second screen, and the method includes:

601. the mobile phone receives a first operation of a user, and the first operation is used for turning on the lighting device.

The illumination device includes at least one of an LED (flashlight), a backlight of a folded screen, and a backlight of a third screen, which is different from the first screen or the second screen, and the third screen may be disposed at a back of the first screen or the second screen. As shown in (B) and (C) of fig. 2B, a third screen (e.g., a C screen) may be provided on the back of the a screen.

The first operation can be a blind operation, namely a gesture which can operate the device without watching a screen, and comprises a blank gesture (also called a floating gesture, namely a gesture control without touch) or a touch gesture (a gesture acting on a shell or a display screen of the mobile phone) input by a user, and can also be a voice control instruction input.

For example, when a user needs to illuminate at night, the user needs to search for a mobile phone in a dim light environment, although the specific position of the mobile phone cannot be determined at any moment, the mobile phone is usually in a range not far from the user, and the user can trigger the mobile phone to turn on an illuminating device by spacing gestures such as waving a palm or waving an arm or closing or opening five fingers. The mobile phone can detect parameters such as height and motion of an input source (palm or arm) on the upper side (left side and right side) of the mobile phone through a depth-sensing camera system (for example, a 3D structured light or time of flight (TOF) sensor), match the detection result with a predefined gesture, and turn on the lighting device if the matching is successful. Or, if the mobile phone is in a place where the user can touch, the user can trigger the mobile phone to turn on the lighting device through a touch gesture. For example, as shown in fig. 7, if the touch trajectory of the user meets a preset touch rule, for example, the moving direction of the touch trajectory is in the direction of a preset angle on the screen of the terminal device (the moving direction of the touch trajectory is in the vertical or horizontal direction on the screen of the terminal device); or, the touch track is in a preset shape (for example, a broken line shape or an arc shape); or the moving distance of the touch track is greater than or equal to a preset distance threshold; or the touch track stays at any position on the screen of the mobile phone, and the staying time is greater than or equal to a preset time threshold; the mobile phone can turn on the lighting device. Alternatively, the user may trigger the mobile phone to turn on the lighting device through the voice control instruction, for example, the user may say "turn on the lighting function" or "turn on the flashlight" or "turn on the backlight" or the like, so as to trigger the mobile phone to turn on the corresponding lighting device.

602. In response to the first operation, the mobile phone turns on the lighting device.

Optionally, before responding to the first operation, the mobile phone determines whether to receive the first operation of the user within a preset time period (a second preset time period), and if the first operation of the user is received within the second preset time period, in response to the first operation, the mobile phone may turn on the lighting device within the second preset time period, and turn off the lighting device in other time periods, so as to save power consumption. The second preset time period is a time period set by the alarm clock, or the second preset time period is determined according to the sleep time of the user, the sleep time of the user can be set by the user or obtained by mobile phone learning, or the second preset time period is determined according to the use habit of the user using the folding screen. For example, the preset time period may be 20:00-07:00, or may be 21:00-06:00, or may be 23:00-08:00, and so on. Therefore, the mobile phone can respond to the first operation in the preset time period to turn on the lighting device, and does not turn on the lighting device in other time periods, so as to better adapt to the user requirements and save power consumption.

Optionally, before responding to the first operation, the mobile phone detects the illumination intensity of the position where the mobile phone is located, and determines that the illumination intensity of the position where the mobile phone is located is less than or equal to a preset illumination intensity threshold. Therefore, when the ambient light intensity is insufficient, the mobile phone can turn on the lighting device. The preset illumination intensity threshold may be a default setting of the mobile phone or a user setting. For example, the preset threshold may be 50 lux.

In some embodiments, after receiving the first operation of the user, the mobile phone may determine the type of the lighting device to be turned on according to the power remaining condition. For example, when the battery of the mobile phone is sufficient (e.g., the battery of the mobile phone is between 100% -60%), the mobile phone may turn on the LED, the backlight of the folded screen, and the backlight of the third screen at the same time. When the power of the mobile phone is insufficient (for example, the power of the mobile phone is between 30% and 10%), the mobile phone may turn on any one of the LED, the backlight of the folding screen, or the backlight of the third screen, so as to save power consumption.

In some embodiments, after receiving the first operation of the user, the mobile phone may determine the type of the lighting device to be turned on according to the specific form. If the mobile phone is in a folded state (for example, the included angle between the first screen and the second screen is between 0 and 10 degrees), the mobile phone can turn on at least one of the LED or the backlight of the third screen; if the mobile phone is in the unfolded state (for example, the included angle between the first screen and the second screen is between 160 and 180 degrees), the mobile phone can turn on the backlight of the foldable screen.

After the mobile phone turns on the lighting device, the initial brightness of the lighting device may be a default setting of the mobile phone, for example, the LED may be defaulted to 50 lumens, the backlight of the third screen may be defaulted to 100 lumens, and the backlight of the folded screen may be defaulted to 150 lumens. Alternatively, the initial brightness of the lighting device may be determined from the current ambient light intensity. For example, after the mobile phone receives the second operation of the user, if the mobile phone detects that the current ambient light intensity is 0.1 lux, the initial brightness of the lighting device may be set to 10 lumens; if the mobile phone detects that the current ambient light intensity is 10 lux, the initial brightness of the lighting device can be set to be 50 lumens. Optionally, the color of the light source of the lighting device may be set by default, or may be set by the user according to the preference of the user. For example, the light source color of the lighting device may be set to warm yellow light, warm white light, cool white light, or the like.

603. And the mobile phone receives a second operation of the user, and the second operation is used for unfolding or folding the folding screen.

The user can adjust the brightness of the lighting device through blind operations such as folding or unfolding the folding screen. For example, when the folding screen is in the folded state, the user may unfold the folding screen or continue to fold the folding screen to adjust the brightness of the lighting device. Alternatively, when the folding screen is in the unfolded state, the user may continue to unfold the folding screen, or fold the folding screen, to adjust the brightness of the lighting device. When the folding screen is in a folding state, an included angle alpha epsilon [0 DEG, P ] between a first screen (such as a screen A) and a second screen (such as a screen B) of the mobile phone. When the mobile phone is in an unfolded state, the included angle alpha epsilon (P, 180 degrees) between the screen A and the screen B of the folding screen, or when the folding screen is in a folded state, the included angle alpha epsilon (0 degrees and P) between the first screen (such as the screen A) and the second screen (such as the screen B) of the mobile phone. When the mobile phone is in an unfolded state, the included angle alpha between the screen A and the screen B of the folding screen belongs to [ P, 180 degrees ]. Where P is a preset angle threshold. P can be the default setting of the mobile phone and can be determined according to the use habit of a large number of users using the folding screen; alternatively, P may be set by the user in the mobile phone.

It can be understood that, in the process of unfolding the folding screen, the included angle between the first screen and the second screen of the folding screen is gradually increased, and in the process of folding the folding screen, the included angle between the first screen and the second screen of the folding screen is gradually decreased. That is, the user can adjust the brightness of the lighting device by adjusting the size of the included angle between the first screen and the second screen. Different included angles may correspond to different brightness, for example, assuming that the lighting device is a backlight of a folded screen, when the included angle between the first screen and the second screen is 30 degrees, the brightness of the backlight of the folded screen may be 200 lumens; when the included angle between the first screen and the second screen is 90 degrees, the brightness of the backlight lamp of the folded screen can be 300 lumens; when the first screen and the second screen are at an angle of 150 degrees, the brightness of the backlight of the folded screen may be 400 lumens. For another example, assuming that the lighting device is an LED, when the included angle between the first screen and the second screen is 30 degrees, the brightness of the LED may be 80 lumens; when the included angle between the first screen and the second screen is 90 degrees, the brightness of the backlight lamp of the folded screen can be 150 lumens; when the first screen and the second screen form an angle of 150 degrees, the brightness of the backlight of the folded screen may be 220 lumens.

Alternatively, the user may determine the type of the lighting device to be turned on through blind operations such as folding or unfolding the folding screen. For example, when the included angle between the first screen and the second screen is less than 180 degrees, the mobile phone turns on the backlight of the folding screen, simultaneously turns on the LED disposed on the folding screen, and turns off the backlight of the third screen disposed on the back of the folding screen and/or the LED disposed on the back of the folding screen, so that the light rays of the lighting device can converge in the same direction, and the lighting brightness is enhanced. When the included angle between the first screen and the second screen is larger than 180 degrees, the backlight lamp of the folding screen can be closed, the LED arranged on the folding screen is closed, the backlight lamp of the third screen arranged on the back of the folding screen and/or the LED arranged on the back of the folding screen are opened, so that the light rays of the illuminating device can be converged in the same direction, and the illumination brightness is enhanced.

604. In response to the second operation, the illumination device is controlled to change the brightness as the angle between the first screen and the second screen is changed.

In response to the second operation, the handset may perform at least one of the following: controlling the brightness of the lighting device to increase along with the increase of the included angle between the first screen and the second screen; or controlling the brightness of the lighting device to be reduced along with the increase of the included angle between the first screen and the second screen; or, the brightness of the lighting device is controlled to be reduced along with the reduction of the included angle between the first screen and the second screen; alternatively, the brightness of the lighting device is controlled to increase as the angle between the first screen and the second screen decreases.

Optionally, before responding to the second operation, the mobile phone detects the illumination intensity of the position where the mobile phone is located, and determines that the illumination intensity of the position where the mobile phone is located is less than or equal to a preset illumination intensity threshold. Thus, when the ambient light intensity is insufficient, the mobile phone can perform the above processing, for example, the mobile phone can slowly light the screen and/or gradually increase the brightness of the LED, protect the vision of the user and meet the lighting requirements of the user. The preset illumination intensity threshold may be a default setting of the mobile phone or a user setting. For example, the preset threshold may be 50 lux.

Optionally, before responding to the second operation, the mobile phone determines whether to receive the second operation of the user within a preset time period (a first preset time period), and if the second operation of the user is received within the preset time period, the mobile phone executes at least one of the above processes in response to the second operation; if the second operation of the user is not received within the preset time period, the mobile phone may not perform the above processing. The first preset time period may be a time period set according to an alarm clock, or the first preset time period may be determined according to a sleep time of the user, or the first preset time period may be determined according to a use habit of the user using the folding screen. For example, the preset time period may be 20:00-07:00, or may be 21:00-06:00, or may be 23:00-08:00, and so on. Therefore, the mobile phone can execute the processing in the first preset time period, and does not execute the processing in other time periods, so that the use habit of the user can be better adapted. The first preset time period and the first preset time period may be the same or different, and the application is not limited.

Optionally, before responding to the second operation, the mobile phone determines whether to receive the second operation of the user within a preset time period, and detects the illumination intensity of the location where the mobile phone is located, and if the second operation of the user is received within the preset time period and the illumination intensity of the location where the mobile phone is located is less than or equal to a preset threshold, in response to the second operation, the mobile phone executes at least one of the above processes.

In one possible design, the second operation is to unfold or fold the angle between the first screen and the second screen to any angle within a preset angle (angle) range and keep the angle for a first preset time. It will be appreciated that when a user wishes to normally use a folding screen handset, the folding screen is typically opened to a maximum angle (e.g., 180 degrees), whereas when the user unfolds or folds the folding screen to within a preset angle range and maintains the configuration (e.g., the user opens the folding screen to 30 degrees and maintains the configuration), there is a high probability that the user wants the handset to be illuminated. Therefore, when the mobile phone detects that the user unfolds or folds the folding screen to the preset angle range and keeps the state, if the folding screen or the third screen is in the black screen state and the LED is in the closed state, the mobile phone may perform at least one of the following processes: and controlling the folding screen to be lightened from a black screen state, and starting the LED or lightening the third screen from the black screen state. If the mobile phone detects that the user unfolds or folds the foldable screen to the preset angle range and keeps the state, the foldable screen or the third screen is in a bright screen state and displays interface contents (such as application icons, basic state information, screen locking information and the like), and the LED is in a closed state, after the mobile phone detects that the user unfolds or folds the foldable screen to the preset angle range and keeps the state, the mobile phone can not display the interface contents on the foldable screen or the third screen and adjust the brightness of the backlight of the current screen to be the preset brightness corresponding to the preset angle, and/or turn on the LED. And then, the mobile phone adjusts the illumination brightness according to the change of the included angle of the folding screen. Alternatively, the cell phone may change the light source color of the current backlight, for example from cool white to warm white, to suit the lighting needs of the user.

In some embodiments, in response to the second operation, the cell phone controls the brightness of the lighting device to increase as the included angle between the first screen and the second screen increases and/or controls the brightness of the lighting device to decrease as the included angle between the first screen and the second screen decreases within a first preset angle range (e.g., between 0-180 degrees, 180 degrees corresponding to a maximum brightness). For example, as shown in fig. 8, taking the lighting device as a folding backlight, when the included angle between the a screen (not completely shown in the figure) and the B screen is 30 degrees, the brightness of the folding backlight may be 60 lux; when the included angle between the A screen and the B screen is 120 degrees, the brightness of the backlight lamp of the folding screen can be 100 lux. Or, in the first preset angle range, the brightness of the lighting device is controlled to be reduced along with the increase of the included angle between the first screen and the second screen, and/or the brightness of the lighting device is controlled to be increased along with the reduction of the included angle between the first screen and the second screen. For example, taking the lighting device as a folding screen backlight, when the included angle between the a screen (not fully shown in the figure) and the B screen is 30 degrees, the brightness of the folding screen backlight may be 100 lux; when the included angle between the A screen and the B screen is 120 degrees, the brightness of the backlight lamp of the folding screen can be 60 lux.

In some embodiments, in response to the second operation, the brightness of the lighting device is controlled to increase with an increase in the angle between the first screen and the second screen (in which case the user may wish to unfold the foldable screen for illumination and may gradually increase the display brightness) and/or the brightness of the lighting device is controlled to decrease with a decrease in the angle between the first screen and the second screen (in which case the user may wish to fold the foldable screen to turn off the lighting function and may gradually decrease the display brightness until the lighting function is turned off) within a second predetermined angle range (e.g., between 0-90 degrees, 90 degrees corresponding to a maximum brightness); within a third preset angle range (for example, between 90 and 180 degrees, 90 degrees corresponds to the maximum brightness), the brightness of the lighting device is controlled to decrease as the included angle between the first screen and the second screen increases (in this case, the user may want to use the mobile phone normally, and the display brightness may be adjusted to a normal level slowly), and/or the brightness of the lighting device is controlled to increase as the included angle between the first screen and the second screen decreases (in this case, the user may want to converge the illumination of the folding screen for lighting, and the display brightness may be adjusted to a normal level slowly).

In one possible design, the illumination device is controlled to change the brightness as the included angle between the first screen and the second screen is changed within a third preset time period. And after a third preset time period, controlling the brightness of the lighting device to be unchanged along with the increase or decrease of the included angle between the first screen and the second screen. The third preset time period is preset by the user, or the third preset time period is determined according to the using habit of the user using the folding screen. That is to say, in the third preset time period, the user can adjust the brightness intensity of the lighting device by adjusting the included angle between the first screen and the second screen. After the third preset time period, the brightness of the lighting device is unchanged, and at the moment, the user can readjust the included angle between the first screen and the second screen to find the holding mode and angle which the user likes. The third preset time period can be reminded by voice, for example, when the user adjusts the brightness, the mobile phone can send out a reminding voice, that 'please adjust the illumination brightness by adjusting the included angle of the folding screen within 3 seconds'.

In a possible design, after the user adjusts the included angle between the first screen and the second screen to a certain angle (for example, to 60 degrees), the brightness, the type, or the light source color of the lighting device may be adjusted through the volume key of the third screen or the mobile phone or the side touchable area of the mobile phone. For example, a shortcut may pop up on the third screen to adjust the lighting device brightness, type or light source color, the user may choose to increase the brightness of the lighting device, or the user may choose to turn off or on part of the lighting device, e.g. turn off or on the LEDs, or the user may change the light source color from white to warm yellow, etc. Alternatively, the user may control the lighting device to a higher brightness by pressing the volume "+" key and to a lower brightness by pressing the volume "-" key. Alternatively, the user may tap on the side with a finger, control the lighting device to increase brightness, and so on.

Optionally, when the backlight of the foldable screen or the backlight of the third screen is turned on, the display area of the foldable screen or the third screen may not display the interface content (e.g., an application icon, basic state information, screen locking information, etc.), or the display area of the foldable screen or the third screen may display the interface content. For example, when the angle at which the user opens the folding screen is smaller than a preset angle (e.g., smaller than 90 degrees), the possibility that the user wants to operate the mobile phone through the folding screen is low, the mobile phone may not call the interface display function, the interface content may not be displayed temporarily in the display area of the folding screen or the third screen, and if it is detected that the angle at which the user opens the folding screen is larger than the preset angle, the possibility that the user wants to operate the mobile phone through the folding screen is high, so the mobile phone may call the interface display function, and the interface content is displayed in the display area of the folding screen or the third screen.

Optionally, the mobile phone may further receive a third operation of the user, and control the color of the lighting device to change according to a preset rule. The third operation may include a gesture operation (e.g., shaking the cell phone) or a voice operation (e.g., the user saying "change the light color"). For example, the first preset rule may be to flash alternately in at least two colors, for example, in red and green. Or the first preset rule may be that the angle between the first screen and the second screen is changed, for example, when the angle between the first screen and the second screen is 10 °, the lighting device is red, when the angle between the first screen and the second screen is 20 °, the lighting device is orange, and so on. Therefore, when the user is in a special scene such as a concert or a party, the color of the lighting device can be controlled to change according to a preset rule, and the use experience of the user is improved.

In some embodiments, if the mobile phone is detected to be in a motion state, the lighting device is controlled to be continuously turned on (i.e., normally on). And if the mobile phone is detected to be in a static state, controlling the lighting device to be closed after a second preset time. For example, the second preset time period may be 1s, 2s, 3s, or the like.

In some embodiments, if it is detected that the included angle between the first screen and the second screen is smaller than a first preset angle, at least one of the LED, the backlight of the folding screen, and the backlight of the third screen may be turned off; if the included angle between the first screen and the second screen is larger than a second preset angle, at least one of the LED and a backlight of the third screen can be turned off. For example, when it is detected that the angle between the first screen and the second screen is less than 90 degrees, the LED, the backlight of the third screen, and the backlight of the folded screen may be turned off. When the included angle between the first screen and the second screen is detected to be larger than 160 degrees, the LED and the backlight of the third screen can be turned off, and the backlight of the folding screen is controlled to be matched with the current ambient light illumination again, so that a user can normally use the folding screen device or normally operate the folding screen device.

Based on the method provided by the embodiment of the application, the user can make the brightness of the lighting device change along with the change of the included angle between the first screen and the second screen by unfolding or folding the folding screen, the operation is simple and convenient, the lighting brightness can be adjusted through blind operation, the user does not need to carry out a complex operation process on the screen, the lighting brightness can be gradually increased along with the operation of the user, the lighting device is prevented from being dazzled when being opened, the vision of the user can be protected, and the user experience can be improved.

As shown in fig. 9, an embodiment of the present application provides a method for illuminating a folding screen, where an electronic device is a mobile phone, a folding screen of the mobile phone is a three-folding screen, and the three-folding screen is foldable to form a first screen (for example, a screen B in fig. 3A or 3B), a second screen (for example, a screen a in fig. 3A or 3B), and a fourth screen (for example, a screen C in fig. 3A or 3B), including:

901. the mobile phone receives a first operation of a user, and the first operation is used for turning on the lighting device.

The correlation process may refer to step 601.

902. In response to the first operation, the mobile phone turns on the lighting device.

The correlation process may refer to step 602.

903. The mobile phone receives a second operation of the user, and the second operation is used for unfolding or folding the folding screen.

The correlation process may refer to step 603.

In the embodiment of the application, the first screen and the second screen are connected by the first folded edge, and the fourth screen and the first screen are connected by the second folded edge (of course, the fourth screen may also be connected by the second folded edge with the second screen). The user can adjust the brightness of the lighting device through blind operations such as folding or unfolding the three-folding screen. When a user folds or unfolds the three-fold folding screen, the first screen and the second screen can be folded or unfolded; alternatively, the first screen and the fourth screen may be folded or unfolded; alternatively, the first and fourth screens may be folded or unfolded simultaneously with the folding or unfolding of the first and second screens.

904. In response to the second operation, the illumination device is controlled to change the brightness as the sum of the angle of the first screen and the second screen and the angle of the fourth screen and the first screen changes.

In response to the second operation, the handset performs at least one of the following: controlling the brightness of the lighting device to increase along with the increase of the sum of the included angle between the first screen and the second screen and the included angle between the fourth screen and the first screen; or controlling the brightness of the lighting device to be reduced along with the increase of the sum of the included angle between the first screen and the second screen and the included angle between the fourth screen and the first screen; or controlling the brightness of the lighting device to be reduced along with the reduction of the sum of the included angle between the first screen and the second screen and the included angle between the fourth screen and the first screen; alternatively, the brightness of the lighting device is controlled to increase as the sum of the angle between the first screen and the second screen and the angle between the fourth screen and the first screen decreases.

The correlation process may refer to step 604.

The user can adjust the brightness of the lighting device by adjusting the size of the included angle between the first screen and the second screen and the size of the included angle between the first screen and the fourth screen. The different included angles may correspond to different brightness, for example, assuming that the lighting device is a backlight of the folded screen, when the sum of the included angle between the first screen and the second screen and the included angle between the first screen and the fourth screen is 30 degrees (for example, the included angle between the first screen and the second screen is 30 degrees, and the included angle between the first screen and the fourth screen is 0 degree; or the included angle between the first screen and the second screen is 0 degree, and the included angle between the first screen and the fourth screen is 30 degrees; or the included angle between the first screen and the second screen is 10 degrees, and the included angle between the first screen and the fourth screen is 20 degrees; etc.), the brightness of the backlight of the folded screen may be 200 lumens; when the sum of the included angle between the first screen and the second screen and the included angle between the first screen and the fourth screen is 90 degrees, the brightness of the backlight lamp of the folded screen can be 300 lumens; when the sum of the angle between the first and second screens and the angle between the first and fourth screens is 150 degrees, the brightness of the backlight of the folded screen may be 400 lumens. For another example, assuming that the lighting device is an LED, when the sum of the included angle between the first screen and the second screen and the included angle between the first screen and the fourth screen is 30 degrees, the brightness of the LED may be 80 lumens; when the sum of the included angle between the first screen and the second screen and the included angle between the first screen and the fourth screen is 90 degrees, the brightness of the backlight lamp of the folded screen can be 150 lumens; when the sum of the angle between the first screen and the second screen and the angle between the first screen and the fourth screen is 150 degrees, the brightness of the backlight of the folded screen may be 220 lumens.

It should be noted that when the included angles between different screens are accumulated (for example, the included angle between the first screen and the second screen and the included angle between the first screen and the fourth screen are accumulated), the included angle turned inward may be set to be positive, and the included angle turned outward may be set to be negative; or the included angle of the outward turning and the inward turning can be set to be positive, and the included angle of the inward turning and the inward turning can be set to be negative; alternatively, the included angle of the inward turning or the outward turning may be set to be the same as positive, and is not limited herein.

In one possible design, in response to the second operation, the mobile phone controls the brightness of the lighting device to increase as the sum of the included angle between the first screen and the second screen and the included angle between the fourth screen and the first screen increases, and controls the brightness of the lighting device to decrease as the sum of the included angle between the first screen and the second screen and the included angle between the fourth screen and the first screen decreases.

In one possible design, in response to the second operation, the mobile phone controls the brightness of the lighting device to decrease as the sum of the included angle between the first screen and the second screen and the included angle between the fourth screen and the first screen increases, and controls the brightness of the lighting device to increase as the sum of the included angle between the first screen and the second screen and the included angle between the fourth screen and the first screen decreases.

Similarly, if the folding screen of the mobile phone is a four-fold folding screen, a five-fold folding screen, or a six-fold folding screen, the user can adjust the brightness of the lighting device by adjusting the included angle between every two adjacent screens.

Based on the method that this application embodiment provided, the user can be through expanding or folding screen makes the luminance of lighting device change along with the contained angle of first screen and second screen and the change of the sum of the contained angle of fourth screen and first screen, and is easy and simple to handle, can adjust illumination luminance through blind operation, need not the user and carry out complicated operation process on the screen, and illumination luminance can be along with user's operation crescent, avoids lighting device to open the moment light too dazzling, can protect user's eyesight to can improve user experience.
