Referring to fig. 1, the present embodiment provides a foldable electronic device 100, where the foldable electronic device 100 may be, but is not limited to, an electronic device such as a mobile phone, a tablet computer, a game console, and the like. The foldable electronic device 100 of the present embodiment is described by taking a mobile phone as an example.
The foldable electronic device 100 includes a foldable housing assembly 100, a foldable screen 120, and an electronic assembly (not shown) disposed in the foldable housing assembly 100, wherein the foldable screen 120 is laid on the foldable housing assembly 100. The foldable housing assembly 100 is used to carry the foldable screen 120 while shielding the electronic components.
The foldable housing assembly 100 includes a first housing 111, a second housing 112, and a rotation shaft mechanism 113, and the first housing 111 and the second housing 112 are respectively connected to both sides of the rotation shaft mechanism 113. The second housing 112 can be folded or unfolded relative to the first housing 111 through the rotating shaft mechanism 113, so that the foldable housing assembly 100 drives the foldable screen 120 to fold or unfold, and when the foldable housing assembly 100 and the foldable screen 120 are folded, the foldable electronic device 100 has a relatively small volume and is convenient to store and carry.
The first casing 111 includes a first middle frame 1111 and a first cover 1112. One side of the first middle frame 1111 is connected to the hinge mechanism 113, which is used to support a part of the electronic components. The first cover 1112 covers the first middle frame 1111. When the first casing 111 and the second casing 112 are overlapped, the first cover 1112 and the second casing 112 are overlapped, that is, the first cover 1112 is attached to the second casing 112. The second housing 112 includes a second middle frame 1121 and a second cover 1122. One side of the second middle frame 1121 is connected to a hinge mechanism 113, which is used for carrying a part of the structure of the electronic component. The second cover 1122 covers the second middle frame 1121. When the first casing 111 and the second casing 112 are overlapped, the second cover 1122 overlaps the first cover 1112, that is, the second cover 1122 fits to the first cover 1112.
The folding screen 120 is sequentially laid on the first housing 111, the rotating shaft mechanism 113, and the second housing 112. In this embodiment, the folding screen 120 is a flexible display screen. The foldable screen 120 is folded or unfolded when the first housing 111 and the second housing 112 are turned over.
Referring to fig. 1 and fig. 2, in the present embodiment, the foldable screen 120 includes a first screen area 121 connected to the first casing 111, a second screen area 122 connected to the second casing 112, and a bent screen area 123 connected to the first screen area 121 and the second screen area 122. The first screen area 121 and the second screen area 122 are folded or unfolded relatively with the first case 111 and the second case 112, respectively. The folding screen area 123 is folded or unfolded according to the folding or unfolding of the first screen area 121 and the second screen area 122. In some embodiments, the first screen area 121, the second screen area 122, and the bent screen area 123 may be an integrated structure, so that the foldable screen 120 is a one-piece flexible display screen; alternatively, in some other embodiments, the bending screen area 123 is a flexible portion that can be bent, and the first screen area 121 and the second screen area 122 can be non-flexible portions, and the first screen area 121 and the second screen area 122 are relatively folded or unfolded by the bending screen area 123. In this embodiment, when the first casing 111 and the second casing 112 are overlapped, the first screen area 121 and the second screen area 122 are separated from each other, so that the electronic device 100 has a folded-out screen structure, and a user can observe the display content of the foldable screen 120 even when the electronic device 100 is folded, thereby improving the convenience of use of the electronic device 100. In some other embodiments, when the first casing 111 and the second casing 112 are overlapped, the first screen area 121 and the second screen area 122 are overlapped, so that the electronic device 100 is in a folded-in screen structure, so that the foldable screen 120 is protected from scratch.
It should be understood that the names of the first screen area 121, the second screen area 122, and the bent screen area 123 are set for convenience of description only and are not intended to be a structural limitation of the foldable screen 120, and in an actual application scenario, the first screen area 121, the second screen area 122, and the bent screen area 123 may not have obvious boundaries, or the foldable screen 120 may appear in other division structures. For example, the foldable screen 120 includes a first screen area 121 and a second screen area 122 connected to the first screen area 121, and the first screen area 121 and the second screen area 122 can rotate relatively to fold or unfold.
In the electronic device 100 provided in the above embodiment of the present application, the electronic device 100 includes the first casing 111, the second casing 112, the first screen area 121 corresponding to the first casing 111, and the second screen area 122 corresponding to the second casing 112, which are foldable relatively, so that the electronic device 100 is presented as a two-fold electronic device that can be folded in half. It is understood that, referring to fig. 3, in some embodiments, the electronic device 100 may further include a third casing 114 and a corresponding third screen area 127, the third casing 114 is rotatably connected between the first casing 111 and the second casing 112, and the third screen area 127 is disposed on the third casing 114 and connected between the first screen area 121 and the second screen area 122. At this time, both the first casing 111 and the second casing 112 can rotate relative to the third casing 114, and both the first screen region 121 and the second screen region 122 can be folded relative to the third screen region 127, so that the electronic device 100 is a tri-folding electronic device capable of being folded twice. In some embodiments, the display area of the third screen area 127 may be substantially the same as the display area of the first screen area 121 and the display area of the second screen area 122, so that the first screen area 121, the second screen area 122, and the third screen area 127 may be folded into a three-layer structure. In some embodiments, the display area of the third screen region 127 may be equal to or greater than the sum of the display area of the first screen region 121 and the display area of the second screen region 122, and when folded, the first screen region 121 and the second screen region 122 may be simultaneously folded to fit the third screen region 127. It is understood that the third casing 114 and the third screen area 127 thereon can be disposed at other positions. For example, the third housing 114 may be rotatably connected to a side of the first housing 111 away from the second housing 112, or the third housing 114 may be rotatably connected to a side of the second housing 112 away from the first housing 111. It is also understood that the electronic device 100 may further include a fourth casing (not shown in the drawings) and a corresponding fourth screen region (not shown in the drawings), or the electronic device 100 may further include a fifth casing (not shown in the drawings) and a corresponding fifth screen region (not shown in the drawings), so that the electronic device 100 is an electronic device in a multi-fold structure, and thus the electronic device 100 has a smaller storage volume on the premise of ensuring that the electronic device 100 has a larger display area, which is beneficial to storage and carrying of the electronic device 100.
In this embodiment, the foldable electronic device 100 further includes an angle detection module 130 (please refer to fig. 1), and the angle detection module 130 is used for detecting an angle formed between the first housing 111 and the second housing 112. In some embodiments, the angle detection module 130 includes, but is not limited to: angle sensors and distance sensors. For example, the angle detecting module 130 may be a hall angle sensor, which may be connected to any one of the first housing 111, the second housing 112, or the rotating shaft mechanism 113.
In some embodiments, the foldable electronic device 100 may further include two motion sensors 140 (please refer to fig. 1), where the two motion sensors 140 are respectively disposed on the first housing 111 and the second housing 112 for respectively detecting the motion states of the first housing 111 and the second housing 112. The motion sensor 140 may include, but is not limited to including: speed sensors, gravity sensors, inertial measurement units, and the like.
At present, in order to obtain the optimal brightness of a screen of an electronic device in real time and improve the comfort level of a user, a light sensing device is usually added on the screen of the electronic device, and the light intensity of the external environment of the electronic device is obtained through the light sensing device, so as to adjust the display brightness of the screen. Obviously, the existing screen brightness adjustment is mainly based on an optical sensor, and the environmental change of the electronic device can be accurately judged through the optical sensor, but the environmental brightness at the user side cannot be judged, because the two types of environmental brightness have brightness difference in some scenes. Meanwhile, due to differences among individual users, the existing automatic brightness adjusting mode cannot well meet the requirements of each user, namely, the optical sensor and the existing automatic brightness adjusting mode cannot bring the best experience to the user. In addition, in the field of folding screens, users often need to switch between two or more display screens, and effective adjustment of different screen brightness cannot be achieved only by one illumination sensor at the moment, and the final display brightness of the screen of the electronic equipment cannot meet the actual requirements of the users.
Therefore, in order to overcome the above-mentioned drawback, as shown in fig. 4, an embodiment of the present application provides a brightness adjustment method applied to an electronic device, where the method may include steps S210 to S230.
Step S210: and acquiring the reference brightness of the electronic equipment.
In one embodiment, the electronic device may be provided with a light sensing device, which is a sensor for detecting the light intensity of the external environment of the electronic device, and is generally installed on the front side of the screen of the electronic device to obtain the light intensity of the external environment on the front side of the screen when the electronic device is used. In addition, the electronic equipment can also monitor the light intensity of the environment through a front camera, an infrared camera and the like.
After the intensity of the external environment is obtained, the electronic device can obtain the reference brightness according to a preset brightness regulation rule and the light intensity of the external environment. The brightness adjustment rule may be a mapping relationship between the external environment intensity and the brightness stored in the electronic device. After the light sensing device is used for obtaining the illumination intensity of the external environment, the electronic equipment can also use the brightness adjustment model to automatically obtain the reference brightness, namely, the light intensity of the external environment is input into the trained brightness adjustment model, and the brightness adjustment model can automatically obtain the corresponding reference brightness according to the illumination intensity.
Step S220: and acquiring brightness adjusting parameters which comprise the pupil state of the user pupil or the relative position relation between the user pupil and the electronic equipment.
The electronic device in this embodiment may include a proximity sensor, a gyroscope sensor, a camera, and other devices, which are used to acquire the brightness adjustment parameter. The brightness adjustment parameter may include a pupil state of a pupil of the user, a relative position relationship between the pupil of the user and the electronic device, or a folding angle of the electronic device.
The pupil state of the pupil of the user refers to the size of the pupil of the user when using the electronic device, which may include the diameter size, radius size, and the like of the pupil. The embodiment can capture the pupil image of the user through the front camera of the electronic device, and then acquire the size of the pupil according to the pupil image, thereby acquiring the pupil state of the pupil of the user. The pupil state of the user's pupil can be obtained by other means according to actual needs by those skilled in the art. For example, the pupil state of the pupil of the user is acquired by an infrared sensor. In different brightness environments, human eyes have different brightness senses for the same actual brightness, so the pupil state of the pupil of the user is used as the brightness adjustment parameter in this embodiment.
The relative position relationship between the user pupil and the electronic device refers to the relative position relationship between the user pupil and the electronic device when the user uses the electronic device, and the relative position relationship can be acquired by using a front camera, a proximity sensor, an infrared sensor or the like. The main reason why the relative position relationship between the pupil of the user and the electronic device is used as the brightness adjustment parameter in this embodiment is as follows: when a user uses the electronic device, when the relative position relationship is increased, the light entering the pupil of the user is reduced, and at this time, the screen brightness of the electronic device needs to be increased. When the relative position relationship is decreased, the light entering the pupil of the user is increased, and at this time, the screen brightness of the electronic device needs to be decreased. Therefore, the screen brightness of the electronic device can be adjusted through the relative position relationship between the pupil of the user and the electronic device. In one embodiment, the relative positional relationship between the user pupil and the electronic device may include a relative distance between the user pupil and the electronic device, a relative angle between the user pupil and the electronic device, and the like.
In addition, when the electronic device is a folding screen, the brightness adjustment parameter may also include a folding angle of the electronic device, and the brightness of the electronic device may also be adjusted by detecting the folding angle in real time. The brightness adjustment parameters specifically include those which are not specifically limited, and may be set according to actual requirements.
Step S230: and adjusting the reference brightness by using the brightness adjusting parameter.
After the brightness adjustment parameters are acquired, the electronic device adjusts the acquired reference brightness according to the brightness adjustment parameters, and the brightness adjustment parameters including the pupil state of the user pupil and the relative position relationship between the user pupil and the electronic device can be known through the introduction. In an embodiment, the reference brightness of the electronic device may be adjusted according to a pupil state of a user pupil, or may be adjusted according to a relative positional relationship between the user pupil and the electronic device, or may be adjusted by combining two types of brightness adjustment parameters, that is, a pupil state of the user pupil and a relative positional relationship between the user pupil and the electronic device.
According to the brightness adjusting method provided by the embodiment of the application, the screen brightness of the electronic equipment is adjusted by acquiring the reference brightness and the brightness adjusting parameter of the electronic equipment, and the relation between a user and the screen of the electronic equipment can be fully considered when the screen brightness is adjusted, so that the finally acquired screen brightness can better meet the actual requirements of the user.
Referring to fig. 5, another embodiment of the present application provides a brightness adjusting method applied to an electronic device including a light sensing device, where the brightness adjusting method may include steps S310 to S370.
Step S310: and acquiring the reference brightness of the electronic equipment.
Referring to fig. 6, step S310 may include steps S311 to S312.
Step S311: and acquiring the ambient brightness of the electronic equipment by using the light sensing device.
Electronic equipment can be provided with the light sense device in this embodiment, can acquire through this light sense device electronic equipment locates external environment's illumination intensity, this application can utilize the light sense device to acquire electronic equipment's ambient brightness promptly. In addition, the light sensing devices are mounted on different screens of the electronic equipment, namely the light sensing devices can be mounted according to the number of the screens. In other words, when the electronic device is a single screen, the light sensing device may be mounted on the front surface of the electronic device, and when the electronic device is a dual-screen or multi-screen electronic device, one light sensing device may be mounted on the front surface corresponding to each screen, so that the light sensing device can accurately obtain the light intensity corresponding to each screen.
Step S312: and acquiring the reference brightness of the electronic equipment according to the ambient brightness.
The light sensing device acquires the ambient brightness, and can acquire the reference brightness corresponding to the ambient brightness according to the corresponding relationship between the ambient brightness and the reference brightness. For example, the reference luminance of the corresponding electronic device is 25 when the ambient luminance is [0, 200], the reference luminance of the corresponding electronic device is 70 when the ambient luminance is [400, 1000], or the reference luminance of the corresponding electronic device is 250 when the ambient luminance is [3000, infinity ]. How the ambient brightness and the reference brightness correspond specifically is not described in detail here, and may be set according to actual conditions.
Step S320: and acquiring a brightness adjustment parameter, wherein the brightness adjustment parameter comprises a pupil state of a user pupil or a relative position relation between the user pupil and the electronic equipment.
The pupil state of the user pupil refers to the size of the user pupil when the user uses the electronic device, and may be, but not limited to, acquired by processing and analyzing an image acquired by the front-facing camera. In addition, in this embodiment, the relative position relationship between the user pupil and the electronic device may include a relative distance and a relative angle between the screen of the electronic device and the user pupil. The relative distance between the screen of the electronic device and the user's pupil may be, but is not limited to, acquired using proximity sensor acquisition, infrared ranging techniques, or acquired by processing and analyzing images captured by a front-facing camera. The relative angle between the screen of the electronic equipment and the pupil of the user refers to an included angle between the sight line of the pupil of the user and the screen of the electronic equipment.
Step S330: and acquiring the designated brightness corresponding to the brightness adjustment parameter.
By the introduction, after the electronic device obtains the ambient brightness, the reference brightness corresponding to the electronic device can be obtained according to the ambient brightness, and after the reference brightness is obtained, the electronic device can obtain the brightness adjustment parameter by using the front camera, the proximity sensor or the infrared sensor, and the like, and fine-tune the reference brightness according to the brightness adjustment parameter to obtain the specified brightness. Wherein, the brightness adjustment parameter may be at least one of a pupil state of a pupil of the user, a relative distance and a relative angle between a screen of the electronic device and the pupil of the user. In other words, the specified brightness may be obtained by the pupil state of the user's pupil; the relative distance between the screen of the electronic equipment and the pupil of the user can be obtained; or the relative angle between the screen of the electronic device and the pupil of the user can be obtained; and may even be obtained using any combination of these three brightness adjustment parameters. For example, after the reference luminance is acquired, the electronic device first acquires the relative distance between the screen of the electronic device and the pupil of the user, and the specified luminance may be acquired directly using the relative distance. How to obtain the corresponding designated brightness by using the brightness adjustment parameter is not described in detail herein.
Step S340: and adjusting the reference brightness to be initial brightness according to the specified brightness.
After the electronic device obtains the specified brightness in the above manner, the reference brightness may be adjusted according to the specified brightness, and then the initial brightness is obtained. When the brightness is adjusted, the reference brightness can be adjusted by utilizing a brightness fine adjustment mode, and the brightness fine adjustment is mainly performed according to the brightness adjustment range and the ambient brightness.
Step S350: detecting whether the brightness adjusting parameter is changed.
After the initial brightness is obtained, the electronic equipment can obtain the brightness adjustment parameter in real time, compare the brightness adjustment parameter obtained at the target moment with the historical brightness adjustment parameter before the target moment, and indicate that the brightness adjustment parameter is changed when the obtained brightness adjustment parameter is different from the historical brightness adjustment parameter. As can be known from the above description, the brightness adjustment parameter may be at least one of a pupil state of a pupil of the user, a relative distance and a relative angle between a screen of the electronic device and the pupil of the user. Therefore, in this embodiment, when detecting whether the brightness adjustment parameter is changed, the three brightness adjustment parameters may be detected and determined respectively, and the process proceeds to step S360 as long as one of the brightness adjustment parameters is changed.
Step S360: and if so, acquiring the change information of the brightness adjustment parameter.
As can be known from the above description, when the brightness adjustment parameter is changed, step S360 is performed, that is, when the brightness adjustment parameter is increased, the initial brightness is increased according to the brightness adjustment range; and when the brightness adjusting parameter is reduced, reducing the initial brightness according to the brightness adjusting amplitude. At the initial brightness, when the relative distance or relative angle between the screen of the electronic device and the pupil of the user is detected to be increased or decreased, the brightness of the screen of the electronic device is increased or decreased correspondingly. In addition, the screen brightness of the electronic device under different environments can be adjusted according to the principle of relativity of human eyes to actual brightness and darkness and the change of the pupil size, that is, the pupil becomes large to represent that the light received by the eyes becomes small, at this time, the brightness of the screen needs to be increased, and the pupil becomes small to represent that the light received by the eyes becomes large, at this time, the brightness of the screen needs to be reduced.
Obviously, when the brightness adjustment parameter changes, the electronic device may obtain change information of the brightness adjustment parameter, where the change information refers to information of increasing or decreasing the brightness adjustment parameter, and if the brightness adjustment parameter is different, the corresponding change information is different. For example, if the relative distance between the screen of the electronic device and the pupil of the user at the target time is 40cm, and the historical relative distance before the target time is 30cm, the change information at this time is "the relative distance is decreased by 10cm". For another example, the pupil diameter in the pupil state of the pupil of the user at the target time is about 2.5mm, and the pupil diameter in the historical pupil state before the target time is about 5.3mm directly, then the change information at this time is "pupil diameter increased by 1.8mm in the pupil state", and the like.
Step S370: and adjusting the initial brightness according to the change information to obtain the target brightness.
After obtaining the change information of the brightness adjustment parameter, the electronic device may adjust the initial brightness by using the change information to obtain the target brightness. The initial brightness can be adjusted by utilizing the brightness adjustment amplitude, the initial brightness can be adjusted by utilizing a brightness adjustment model in artificial intelligence, or the initial brightness can be adjusted by utilizing a brightness adjustment rule, and the specific mode of brightness adjustment is not described in detail here.
According to the brightness adjusting method, the screen brightness of the electronic equipment can be accurately and effectively adjusted by combining three brightness adjusting parameters, namely the pupil state of the pupil of the user, the relative distance and the relative angle between the screen of the electronic equipment and the pupil of the user, and finally obtained screen brightness better meets the actual requirement of the eyes of the user on the brightness of the electronic equipment.
Still another embodiment of the present application provides a brightness adjustment method, which is applied to an electronic device including a fold-out screen, where the fold-out screen includes a first screen area and a second screen area that can rotate with respect to each other, and referring to fig. 7, the brightness adjustment method may include steps S410 to S440.
Step S410: detecting a folded state of the electronic device.
The folded state of the electronic device in this embodiment may include an unexpanded state and an expanded state. The first screen area and the second screen area can be completely overlapped in the unfolded state, the first screen area and the second screen area are in a non-contact state in the unfolded state, and an included angle between the first screen area and the second screen area of the outward folding screen is gradually increased in the change process from the unfolded state to the unfolded state.
Therefore, in the two different states, the included angle between the first screen area and the second screen area is different, so that the current folding state of the folding screen can be determined by detecting the angle between the first screen area and the second screen area. In one embodiment, an included angle between the first screen region and the second screen region may be obtained by using a distance sensor, an angle sensor, and the like, and after the included angle is obtained, the folded state of the electronic device may be obtained by using a state obtaining rule. The state obtaining rule refers to the angle ranges corresponding to the first screen area and the second screen area when the outer folding screen is in the non-unfolded state and the unfolded state. For example, a folded state with an angular range of 0 ° to 10 ° is an unexpanded state, while a folded state with an angular range greater than 10 ° is an expanded state.
Step S420: when the folding state of the electronic equipment is the non-unfolding state and the first screen area is the screen area currently used by the user, acquiring the reference brightness of the first screen area.
After the included angle between the first screen area and the second screen area is acquired by using a distance sensor or an angle sensor, the folded state of the electronic equipment can be acquired by using the included angle. When the included angle between the first screen area and the second screen area is within the angle range of the non-unfolded state, the folded state of the electronic equipment is indicated as the non-unfolded state. For example, the angle range of the undeployed state is 0 ° to 10 °, and the angle between the first screen region and the second screen region acquired with the sensor is 5 °. Obviously, 5 ° is located in the angular range of 0 ° to 10 ° in the non-unfolded state, and the folded state of the electronic apparatus is the non-unfolded state at this time. In addition, when the folded state of the electronic equipment is determined to be the unfolded state, whether the first screen area is the screen area currently used by the user is judged, and if yes, the light sensing device installed on the first screen area is used for acquiring the reference brightness of the first screen area.
Step S430: and acquiring the brightness adjusting parameter of the first screen area.
In order to more accurately acquire the target brightness of the first screen area of the fold-out screen, at least one front camera may be installed on the first screen area, and the front camera may be used to acquire a brightness adjustment parameter of the first screen area. The brightness adjustment parameter may include at least one of a pupil state of a user pupil, a relative distance and a relative angle between the user pupil and the first screen region.
Step S440: and adjusting the reference brightness of the first screen area according to the brightness adjustment parameter to obtain a first target display brightness.
After the brightness adjustment parameter of the first screen area is obtained, the reference brightness of the first screen area can be adjusted to be the initial brightness according to the brightness adjustment parameter, then whether the brightness adjustment parameter of the first screen area changes or not is detected, if the brightness adjustment parameter of the first screen area changes, change information corresponding to the change is obtained, the initial brightness is adjusted by the change information, and the target brightness of the first screen area is obtained and is called as first target display brightness.
In addition, as shown in fig. 8, another embodiment of the present application provides an adjusting method further including steps S450 to S470.
Step S450: and when the folded state of the electronic equipment is the unfolded state, acquiring the reference brightness of the second screen region, wherein the reference brightness of the second screen region is smaller than the first target display brightness.
When the included angle between the first screen area and the second screen area exceeds the angle range of the non-unfolded state, the folded state of the electronic equipment is the unfolded state. For example, the angle range of the undeployed state is 0 ° to 10 °, and the angle between the first screen region and the second screen region acquired with the sensor is 105 °. Obviously, 105 ° lies between the angular range of 0 ° and 10 ° beyond the undeployed state, i.e. when the folded state of the electronic device is the deployed state. When it is determined that the folded state of the electronic device is the unfolded state, the reference brightness of the second screen region may be obtained, and the reference brightness of the second screen region is smaller than the first target display brightness, that is, the reference brightness of the second screen region may be set according to the first target display brightness.
As shown in fig. 9, the folded state of the electronic device is an unfolded state, in fig. 9, the first display corresponds to the first screen region, and the second display corresponds to the second screen region. In order to better acquire the brightness adjustment parameter of the electronic device, the first display screen and the second display screen in this embodiment are respectively provided with "light sense/proximity". The light sensation is a light sensation device which is mainly used for acquiring the illumination intensity of the environment where the electronic equipment is located, and the proximity sensor is mainly used for acquiring the position relation between the pupil of the user and the electronic equipment.
Step S460: and acquiring the brightness adjusting parameter of the second screen area.
In order to more accurately acquire the target brightness of the second screen area of the fold-out screen, at least one front camera may be installed on the second screen area, and the front camera may be used to acquire a brightness adjustment parameter of the second screen area. Wherein the brightness adjustment parameter may include at least one of a pupil state of a user pupil, a relative distance and a relative angle of the user pupil to the second screen region.
Step S470: and adjusting the reference brightness of the second screen area by using the brightness adjustment parameter of the second screen area to obtain a second target display brightness.
After the brightness adjustment parameter of the second screen area is obtained, the reference brightness of the second screen area can be adjusted to be the initial brightness according to the brightness adjustment parameter, then whether the brightness adjustment parameter of the second screen area changes or not is detected, if the brightness adjustment parameter of the second screen area changes, change information corresponding to the change is obtained, the initial brightness is adjusted by the change information, and the target brightness of the second screen area is obtained and is called as second target display brightness.
After the adjusting the reference brightness of the second screen region by using the brightness adjustment parameter of the second screen region, the method further includes: and when the folding angle between the first screen area and the second screen area is larger than a preset angle, acquiring a median value of the first target display brightness and the second target display brightness, and adjusting the brightness of the first screen area and the second screen area by using the median value. For example, the folding angle between the first screen area and the second screen area is 145 °, and the preset angle is 135 °, and the display brightnesses of the first screen area and the second screen area are 60 and 66, respectively, and obviously, the folding angle is greater than the preset angle, so that the final display brightness of the first screen area and the second screen area of the electronic device needs to be adjusted by the median 63 of the display brightness of the first screen area and the second screen area.
The brightness adjusting method provided in the embodiment of the application is suitable for the situation that the electronic equipment is a folding screen, and when the electronic equipment is the folding screen, the brightness of the first screen area and the brightness of the second screen area can be respectively adjusted, so that the brightness of the multiple screens can be adjusted, the phenomena of dazzling, halation and the like caused by the brightness difference of the multiple screens can be avoided, and the comfort level of watching the screens by a user is improved.

Step S530: and adjusting the reference brightness by using the brightness adjusting parameter.
Step S540: and judging whether a brightness adjusting instruction is input or not, wherein the brightness adjusting instruction is input by a user based on the electronic equipment.
After adjusting the reference brightness by using the brightness adjustment parameter, the electronic device may detect whether a brightness adjustment instruction is input, where the brightness adjustment instruction is input by a user based on the electronic device. In other words, when the user is not satisfied with the final display brightness of the electronic device, the user may adjust the display brightness of the electronic device by a manual adjustment method, and when the user performs the manual adjustment, the user needs to input a brightness adjustment instruction through the electronic device, that is, the electronic device receives the brightness adjustment instruction input by the user. The brightness adjustment instruction is used for increasing or decreasing the display brightness of the electronic equipment.
Step S550: and if a brightness adjusting instruction is input, acquiring the optimal display brightness corresponding to the brightness adjusting instruction.
And when the brightness adjusting instruction is input, acquiring an adjusting parameter corresponding to the brightness adjusting instruction, wherein the adjusting parameter is used for adjusting the reference brightness, and if the adjusting parameter is different, the adjusting operation on the reference brightness is different. For example, if the brightness adjustment command is to increase the reference brightness by 5, the corresponding adjustment parameter is 5, and if the reference brightness is 65, the adjusted reference brightness is 70, that is, the optimal display brightness of the electronic device is 70.
Step S560: and adjusting the screen brightness of the electronic equipment by using the optimal display brightness.
After the optimal display brightness is obtained, the electronic device can input the optimal display brightness into a brightness adjustment model, and the brightness adjustment model is trained and optimized by using the optimal display brightness.

In addition, after the optimal display brightness corresponding to the brightness adjustment instruction is acquired, the pupil state of the user corresponding to the optimal display brightness may be acquired, and the pupil state may be used as the optimal pupil state. Through the introduction, it can be known that if the external environments of the electronic devices are different, the corresponding brightness adjustment parameters are also different. Therefore, after the brightness of different environments is adjusted by using the brightness adjustment model, the pupil states of the user pupils corresponding to the brightness adjustment model can be stored, then the obtained pupil states of the plurality of user pupils are analyzed to obtain a pupil state transformation data set, and the internal parameters of the electronic device can be adjusted by matching the transformation data set with the optimal pupil state. The built-in parameters may include reference luminance, pupil state and luminance adjustment range of the user's pupil in a default state, and the like.
