Description

Display modules, electronic devices, and screen brightness adjustment methods

[0001] This application claims priority to Chinese Patent Application No. 202411490381.6, filed on October 22, 2024, entitled "Display Module, Electronic Device and Screen Brightness Adjustment Method", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminal technology, specifically to a display module, electronic device, and screen brightness adjustment method. Background Technology

[0003] Screen display is the primary means of interaction between mobile devices such as smartphones and users. The screen brightness that feels comfortable to users varies depending on the ambient light intensity. Typically, mobile devices are equipped with ambient light sensors to detect changes in ambient light intensity and adjust the screen brightness accordingly. However, in related technologies, the field of view (FOV) of ambient light sensors in mobile devices is relatively small, which can easily affect the accuracy of ambient light intensity detection, thus impacting screen brightness adjustment and making it difficult to meet the screen brightness adjustment needs in low-light environments.

[0004] Application content

[0005] In view of this, this application provides a display module, an electronic device, and a screen brightness adjustment method to solve the problem that the field of view of the ambient light sensor in the prior art is small, making it difficult to meet the screen brightness adjustment requirements in low-light environments.

[0006] The first aspect of this application provides a display module including a screen and an ambient light sensor. The screen includes a main body and an outer peripheral body, the outer peripheral body being circumferentially connected to the main body. At least a portion of the ambient light sensor is disposed on the outer peripheral body, the ambient light sensor having a light detection surface, and the light detection surface forming an angle with one side surface of the screen in the thickness direction of the display module.

[0007] In this application, because the light detection surface and the screen have an angle on one side of the display module's thickness direction—that is, the light detection surface is tilted relative to the main body—the normal direction of the light detection surface is also offset relative to the normal direction of the screen. This causes the field of view of the ambient light sensor to also shift outwards along with the light detection surface relative to the main body. Therefore, without changing the field of view of a single ambient light sensor, it makes it easier for light sources from the side to illuminate within the field of view and be detected by the ambient light sensor. This improves the ambient light sensor's ability to perceive light sources from the side, thereby expanding the overall ambient light perception field of view of the electronic device and improving the accuracy of detecting ambient light intensity. Furthermore, the electronic device can also use this to more precisely adjust the screen brightness, meeting the screen brightness adjustment needs in low-light environments and avoiding problems such as the screen being too dim or too bright. This makes the screen brightness more suitable for the user's eye needs and improves the user experience.

[0008] In one possible design, the display module includes a plurality of ambient light sensors, which are spaced apart on the outer periphery.

[0009] Multiple ambient light sensors are spaced apart on the outer periphery, thereby expanding the equivalent field of view of the sensors and further increasing the overall ambient light sensing field of view of the electronic device. This improves the device's ability to perceive ambient light in environments with side or low light sources. The spaced arrangement of multiple sensors reduces the number of sensors required on the screen and avoids overlap between adjacent sensors, ensuring detection accuracy while reducing manufacturing costs. Furthermore, multiple sensors can simultaneously detect ambient light, allowing the electronic device to synthesize the light intensity measurements from each sensor to obtain a more accurate ambient light intensity value and reduce detection errors.

[0010] In one possible design, the light detection surface faces the display side of the screen, that is, the light detection surface of the ambient light sensor faces the outside of the screen, so that the ambient light sensor can directly detect the ambient light. The structure is simple and facilitates the installation of multiple ambient light sensors.

[0011] In one possible design, the angle between the light detection surface and the screen on one side of the display module in the thickness direction is α, where 0° < α ≤ 90°.

[0012] When the angle α between the light detection surface and one side surface of the screen in the thickness direction of the display module satisfies 0°<α≤90°, the field of view of the ambient light sensor faces the front of the electronic device, that is, the field of view of the ambient light sensor faces the display side of the screen, and can avoid the casing of the electronic device from blocking the field of view of the ambient light sensor. This can effectively expand the equivalent field of view of multiple ambient light sensors and improve the accuracy of detecting the light intensity value of ambient light.

[0013] In one possible design, the ambient light sensor is located within the screen.

[0014] This structure allows ambient light sensors to be integrated with the screen, improving the integration of the display module. Multiple ambient light sensors can be installed during screen manufacturing along with other sensors and electronic components integrated within the screen, reducing the difficulty of installing multiple sensors, improving the manufacturing efficiency of electronic devices, and saving costs. Furthermore, by placing the ambient light sensors within the screen, the internal circuitry can be reused to communicate with the processor within the electronic device, further enhancing the integration of the display module. This also eliminates the need to occupy internal space within the electronic device's casing, thus improving the utilization of internal space.

[0015] In one possible design, the display module includes an ambient light detection unit, with the ambient light sensor integrated into the ambient light detection unit to further improve the integration of the display module.

[0016] In one possible design, along the thickness direction of the display module, the ambient light sensor is positioned on the side of the screen away from the display side, thereby increasing the design freedom of the electronic device.

[0017] In one possible design, at least a portion of the outer periphery is bent relative to the main body to form a bending region, and at least a portion of the ambient light sensor is disposed in the bending region.

[0018] At least a portion of the ambient light sensor is located in the bending area, allowing the sensor to be tilted relative to the main body by utilizing the natural curvature of its outer periphery. This creates an angle between the light detection surface and the surface of the main body, facilitating the installation of the ambient light sensor without the need for additional support blocks or other auxiliary installation components. This further reduces the structural complexity of electronic devices, simplifies their fabrication, and saves costs.

[0019] In one possible design, the outer periphery and the main body are located on the same plane, thereby reducing the difficulty of screen fabrication and increasing the design freedom of the display module.

[0020] In one possible design, the display module further includes a proximity sensor for detecting the distance between the ambient light sensor and an obstruction, and emitting a first detection signal.

[0021] Electronic devices can determine whether the ambient light sensor is obstructed based on the first detection signal, thereby eliminating abnormal values ​​from multiple light intensity measurements and selecting the light intensity measurement value from the unobstructed ambient light sensor, i.e., the first light intensity measurement value. This reduces the impact of obstructions on the accuracy of ambient light detection and improves the accuracy of ambient light intensity detection. This method of determining the obstruction status of the ambient light sensor is simple and reliable, facilitating accurate determination of the obstruction status of the ambient light sensor, reducing the complexity of screen brightness adjustment methods, and improving the efficiency and accuracy of screen brightness adjustment.

[0022] In one possible design, the display module further includes a touch sensor for detecting the contact position of an obstruction on the screen and emitting a second detection signal.

[0023] The electronic device can further determine whether the ambient light sensor is obstructed based on the second detection signal, thereby eliminating abnormal values ​​from multiple light intensity measurements and selecting the light intensity measurement value from the unobstructed ambient light sensor, i.e., the first light intensity measurement value. This reduces the impact of obstructions on the accuracy of ambient light detection and improves the accuracy of detecting ambient light intensity values. This method of determining the obstruction status of the ambient light sensor is simple and reliable, further improving the accuracy of determining the obstruction status of the ambient light sensor and further improving the efficiency and accuracy of screen brightness adjustment.

[0024] A second aspect of this application provides an electronic device, including a processor and a display module as described in any of the above embodiments. The processor is electrically connected to the display module. The processor is configured to acquire light intensity measurement values ​​from a plurality of ambient light sensors in the display module, as well as the normal directions of the light detection surfaces of the plurality of ambient light sensors in space, and adjust the screen brightness of the display module according to the plurality of light intensity measurement values ​​and the plurality of normal directions.

[0025] Multiple ambient light sensors can simultaneously detect ambient light. By comparing and analyzing the light intensity measurements from each sensor, the processor can obtain a more accurate ambient light intensity value. Furthermore, by combining the positional information of each sensor's light detection surface, such as the normal direction in space, the orientation of the light source relative to the electronic device can be determined. This allows the electronic device to make more precise adjustments to its screen based on both the ambient light intensity and the light source's orientation, thus improving the user experience.

[0026] In one possible design, the processor includes an ambient light calculation module and a screen brightness adjustment module. The ambient light calculation module determines the ambient light intensity value based on multiple light intensity measurements and sends the ambient light intensity value and multiple normal directions to the screen brightness adjustment module. The screen brightness adjustment module determines the target screen brightness value based on the ambient light intensity value and the adjustment speed based on the multiple normal directions. It then adjusts the screen brightness based on the target screen brightness value and the adjustment speed, thereby obtaining a more accurate ambient light intensity value. Furthermore, the direction of the light source relative to the electronic device can be determined based on the multiple normal directions. Additionally, the rate of change of the direction of the light source relative to the electronic device can be determined based on the normal direction information from multiple ambient light sensors at different times. This allows the electronic device to determine the adjustment speed and adjust the screen brightness accordingly, preventing the screen from flickering between bright and dim.

[0027] A third aspect of this application provides a screen brightness adjustment method, applied to the aforementioned electronic device, the adjustment method comprising:

[0028] Acquire light intensity measurements from multiple ambient light sensors, as well as the normal directions of the light detection surfaces of the multiple ambient light sensors in space.

[0029] In this step, the processor of the electronic device can periodically read the light intensity measurement values ​​of each ambient light sensor, for example, every 100ms, 200ms, 300ms, and 400ms, to adjust the screen brightness in a timely manner based on the real-time ambient light intensity. Simultaneously, the ambient light sensor has a light detection surface, and the direction perpendicular to its light detection surface is the aforementioned normal direction. Since the positions of the multiple ambient light sensors on the screen are different, the positions of their light detection surfaces in space are also different, and the positions of their normal directions in space are also different. Therefore, the electronic device can determine the position of the corresponding ambient light sensor based on the normal direction, and then determine the position of the light source relative to the ambient light sensor based on the light intensity measurement values ​​of each sensor, thereby determining the direction of the light source relative to the electronic device, allowing for more accurate adjustment of the screen brightness.

[0030] The target screen brightness and adjustment speed are determined based on multiple light intensity measurements and multiple normal directions.

[0031] In this step, the processor compares and analyzes multiple light intensity measurements to obtain a more accurate ambient light intensity value, and calculates the target screen brightness most suitable for human viewing under that ambient light condition. The processor can also analyze multiple normal directions to determine the relative position of the light source with respect to the ambient light sensor, thereby determining the positional relationship between the light source and the electronic device. Furthermore, based on the normal direction information from multiple ambient light sensors at different times, the processor can determine the rate of change of the light source's direction relative to the electronic device, allowing the electronic device to determine its adjustment speed accordingly.

[0032] The screen brightness is adjusted according to the target screen brightness and the adjustment speed.

[0033] In this step, the processor adjusts the screen brightness from the current brightness to the target brightness using a specific adjustment speed to meet the user's needs. A faster adjustment speed results in a shorter time for the screen to adjust from the current brightness to the target brightness, while a slower adjustment speed results in a longer time.

[0034] In this embodiment, multiple ambient light sensors can simultaneously detect ambient light, expanding the overall ambient light perception field of view of the electronic device. Furthermore, the electronic device can integrate the light intensity measurements detected by each ambient light sensor to obtain a more accurate ambient light intensity value, reducing detection errors and calculating an accurate target screen brightness. This allows for precise adjustment of the screen brightness, meeting the needs of low-light environments and preventing issues such as excessively dim or bright screens. The resulting screen brightness better suits the user's eye requirements, improving the user experience. Simultaneously, the adjustment speed of the screen brightness can be determined by the normal direction of the light detection surface of each ambient light sensor in space, preventing flickering brightness and further improving the control precision of screen brightness adjustment. This meets the user's eye requirements under different light sources, further enhancing the user experience.

[0035] In one possible design, determining the target screen brightness and adjustment speed based on multiple light intensity measurements and multiple normal directions specifically includes:

[0036] Valid light intensity measurements are selected from the multiple light intensity measurements.

[0037] By analyzing the light intensity measurements obtained from various ambient light sensors, abnormal readings are removed, and valid light intensity measurements are selected to reduce detection errors.

[0038] The ambient light intensity value is determined based on the effective light intensity measurement value.

[0039] In this step, the ambient light intensity value is obtained by calculating the average value of each effective light intensity measurement, which further reduces the detection error.

[0040] The target screen brightness is determined based on the ambient light intensity value.

[0041] In this step, the target screen brightness, which is most suitable for human viewing under the ambient light, is calculated based on the light intensity value. Specifically, the target screen brightness can be determined from a lookup table based on the mapping relationship between ambient light intensity and screen brightness, thereby improving the processor's processing speed.

[0042] By selecting the effective light intensity measurement value from multiple light intensity measurements, and calculating a more accurate target screen brightness based on the effective light intensity measurement value, the detection error can be further reduced, thereby enabling more precise adjustment of the screen brightness.

[0043] In one possible design, the step of filtering valid light intensity measurements from a plurality of light intensity measurements specifically includes:

[0044] Determine the occlusion status of the ambient light sensor.

[0045] In this step, the occlusion status of the ambient light sensor can be determined using auxiliary information such as proximity sensors and touch sensors. Of course, other methods can also be used to determine the occlusion status of the ambient light sensor, and this is not a limitation here.

[0046] The light intensity measurement value of the unobstructed ambient light sensor is obtained, and the light intensity measurement value of the unobstructed ambient light sensor is the first light intensity measurement value.

[0047] In this step, the aforementioned light intensity measurement values ​​include the light intensity measurement values ​​measured by the occluded ambient light sensor and the light intensity measurement values ​​measured by the unoccluded ambient light sensor. In this step, it is necessary to remove the light intensity measurement values ​​measured by the occluded ambient light sensor and retain the light intensity measurement values ​​measured by the unoccluded ambient light sensor. The light intensity measurement value of the unoccluded ambient light sensor is the first light intensity measurement value.

[0048] The threshold value is determined based on the first light intensity measurement value.

[0049] In this step, the threshold value can serve as a reference value to filter out valid light intensity measurements. For example, the threshold value can be determined by the maximum value among the first light intensity measurements. Alternatively, the threshold value can be determined by the average value of the first light intensity measurements.

[0050] Obtain light intensity measurements that are greater than the threshold value from the first light intensity measurements; these light intensity measurements that are greater than the threshold value are considered valid light intensity measurements.

[0051] In this step, the first light intensity measurement value is compared with the threshold value in turn. If the first light intensity measurement value is greater than the threshold value, the first light intensity measurement value is output as a valid light intensity measurement value.

[0052] By judging the occlusion state of the ambient light sensor and determining the threshold value to filter multiple light intensity measurements, more reliable and effective light intensity measurements can be selected for the current environment, thereby further reducing detection errors. Moreover, this method is simple and easy to implement, and can quickly filter multiple light intensity measurements, improving the efficiency of screen brightness adjustment.

[0053] In one possible design, determining the occlusion state of the ambient light sensor specifically includes:

[0054] The distance between the ambient light sensor and the obstruction is detected to be less than a first threshold.

[0055] In this step, a proximity sensor can be set to detect the distance between the ambient light sensor and the obstruction, and a first detection signal can be emitted. This allows the processor to compare the distance between the ambient light sensor and the obstruction with a first threshold based on the first detection signal, thereby determining whether the distance between the ambient light sensor and the obstruction is less than the first threshold.

[0056] If the distance is less than the first threshold, it is determined that the ambient light sensor is blocked.

[0057] In this step, the distance is compared with a first threshold. If the distance is less than the first threshold, it is determined that the ambient light sensor is blocked.

[0058] If the distance is greater than or equal to the first threshold, it is determined that the ambient light sensor is not obstructed.

[0059] In this step, the distance is compared with a first threshold. If the distance is greater than or equal to the first threshold, it is determined that the ambient light sensor is blocked.

[0060] Electronic devices can determine whether an ambient light sensor is obstructed by comparing the distance between the sensor and an obstruction to a first threshold. This allows for the elimination of abnormal values ​​from multiple light intensity measurements, filtering out the light intensity measurement value from the unobstructed sensor (the first light intensity measurement value). This reduces the impact of obstructions on the accuracy of ambient light detection and improves the accuracy of ambient light intensity detection. This method of determining the obstruction status of the ambient light sensor is simple and reliable, facilitating accurate determination of the sensor's obstruction status, reducing the complexity of screen brightness adjustment methods, and improving the efficiency and accuracy of screen brightness adjustment.

[0061] In one possible design, determining the occlusion state of the ambient light sensor further includes:

[0062] The touch sensor emits a second detection signal based on the capacitance change generated when it comes into contact with an obstruction.

[0063] When a human body or an object such as a stylus touches the screen, the touch sensor detects the change in capacitance caused by the contact and sends out a second detection signal. These signals are then transmitted to the processor of the electronic device.

[0064] The contact position of the obstruction on the screen is determined based on the second detection signal.

[0065] In this step, the processor can determine the contact position of the obstruction on the screen based on the second detection signal.

[0066] The occlusion state of the ambient light sensor is determined based on the contact location.

[0067] In this step, the occlusion status of the ambient light sensor can be determined by comparing the contact position with the position of the ambient light sensor.

[0068] Electronic devices can determine whether the ambient light sensor is obstructed based on the second detection signal, thereby further eliminating abnormal values ​​from multiple light intensity measurements and selecting the light intensity measurement value from the unobstructed ambient light sensor, i.e., the first light intensity measurement value. This reduces the impact of obstructions on the accuracy of ambient light detection and improves the accuracy of detecting ambient light intensity values. This method of determining the obstruction status of the ambient light sensor is simple and reliable, further improving the accuracy of determining the obstruction status of the ambient light sensor and further improving the efficiency and accuracy of screen brightness adjustment.

[0069] In one possible design, after selecting the valid light intensity measurement value from the plurality of light intensity measurements, the method further includes:

[0070] Obtain the normal direction in space for each of the ambient light sensors corresponding to the effective light intensity measurement value, wherein the normal direction is the first normal direction.

[0071] In this step, the normal direction of each ambient light sensor corresponding to the effective light intensity measurement value is obtained from the normal directions corresponding to multiple ambient light sensors, that is, the first normal direction. The position of the corresponding ambient light sensor on the electronic device can be determined by the first normal direction, thereby determining the positional relationship of the light source relative to the ambient light sensor, and then determining the direction of the light source relative to the electronic device.

[0072] The direction of the normal is determined based on the first normal direction.

[0073] In this step, the sum normal direction is the resultant direction of multiple first normal directions. When there is only one first normal direction, the sum normal direction is the same as the first normal direction.

[0074] Obtain the sum and normal directions at multiple time points.

[0075] In this step, the sum and normal directions at multiple moments can be obtained through the aforementioned steps.

[0076] The change in the normal direction is determined by the sum of the normal directions at two adjacent moments.

[0077] In this step, if the environment is one where the direction of the ambient light source relative to the electronic device is constantly changing, such as walking under a street lamp, the direction of the light source relative to the electronic device will be different at two adjacent moments. Therefore, the ambient light sensors corresponding to the effective light intensity measurements at those two adjacent moments will be different, and the normal directions of each ambient light sensor corresponding to the effective light intensity measurements will be different in space—that is, the first normal direction will be different. Consequently, the calculated sum normal directions will also be different, resulting in a change in the normal direction. The change in normal direction can be obtained by comparing and subtracting the sum normal directions at two adjacent moments. A larger change in normal direction indicates a faster change in the direction of the ambient light source relative to the electronic device, while a smaller change in normal direction indicates a slower change in the direction of the ambient light source relative to the electronic device.

[0078] The adjustment speed is determined based on the change in the normal direction.

[0079] In this step, the rate of change of the direction of the light source relative to the electronic device between two adjacent moments can be determined based on the change in the normal direction. This allows the processor to determine the corresponding adjustment speed based on the change in the normal direction, enabling the electronic device to adjust the screen brightness using different adjustment speeds under different lighting conditions.

[0080] By analyzing the normal directions of the light detection surfaces of multiple ambient light sensors in space, the direction of the light source relative to the electronic device can be determined. This allows the electronic device to calculate the change in the normal direction based on the sum of the normal directions from multiple ambient light sensors at different times (i.e., the composite normal direction). This allows the device to determine the rate of change in the direction of the light source relative to the electronic device, enabling it to adjust the brightness of the screen accordingly under different ambient light conditions. This avoids flickering brightness and improves the user experience.

[0081] In one possible design, determining the adjustment speed based on the change in the normal direction specifically includes:

[0082] Compare the change in normal direction with a preset threshold.

[0083] In this step, the preset threshold can be used as a reference value to determine the magnitude of the change in the normal direction, so as to determine how fast the direction of the ambient light source changes relative to the electronic device.

[0084] If the change in the normal direction is greater than or equal to the preset threshold, the adjustment speed is determined to be the first speed.

[0085] In this step, the change in the normal direction is compared with a preset threshold. If the change in the normal direction is greater than or equal to the preset threshold, the direction of the light source relative to the electronic device changes faster, that is, the screen brightness is adjusted using the first speed.

[0086] If the change in the normal direction is less than the preset threshold, the adjustment speed is determined to be the second speed.

[0087] In this step, the change in the normal direction is compared with a preset threshold. If the change in the normal direction is less than the preset threshold, the direction of the light source relative to the electronic device changes slowly, and the screen brightness is adjusted using a second speed.

[0088] This method is simple and reliable, improves the accuracy of screen brightness adjustment, meets the eye needs of users using electronic devices in different environments, avoids the phenomenon of screen 1 flickering between bright and dim, and improves the user experience.

[0089] In one possible design, the first speed is less than the second speed, enabling the electronic device to adjust screen brightness at a slower speed in environments where the direction of the light source relative to the electronic device changes rapidly, thus avoiding screen flickering and affecting user experience; conversely, enabling the electronic device to adjust screen brightness at a faster speed in environments where the direction of the light source relative to the electronic device changes slowly, thus allowing the screen to quickly adjust from its current brightness to a target brightness suitable for the user, promptly meeting the user's eye needs and improving the user experience.

The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0109] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0110] Screen display is the primary means of interaction between mobile devices such as smartphones and users. The screen brightness at which users feel comfortable varies depending on the ambient light intensity.

[0111] Please refer to Figure 1, which is a partial structural diagram of a mobile device in the related art.

[0112] As shown in Figure 1, in related technologies, mobile devices typically include a screen 1' and an ambient light sensor 2' disposed at the bottom of the screen. The ambient light sensor 2' has a light detection surface 21', which is used to sense changes in the light intensity value of ambient light and can adjust the screen brightness to the optimal screen brightness according to the changes in the light intensity value of ambient light.

[0113] In the relevant technology, the normal direction of the light detection surface 21' of the ambient light sensor 2' is consistent with the normal direction of the screen 1', that is, the angle between the normal direction of the light detection surface 21' of the ambient light sensor 2' and the normal direction of the screen 1' is 0°. Here, the normal refers to a straight line perpendicular to the surface of the light detection surface 2' or the screen 1'.

[0114] Please refer to Figure 2 simultaneously. Figure 2 is a response curve of an ambient light sensor to incident light at different angles. In Figure 2, the horizontal axis represents the angle between the incident light source and the normal direction of the light detection surface 21' of the ambient light sensor 2', and the vertical axis represents the response of the ambient light sensor 2' to the incident light source. The greater the response, the larger the detection value of the ambient light sensor 2'. As shown in Figure 2, when the incident light source is directly above the light detection surface 21', that is, when the angle between the incident light source and the normal direction of the light detection surface 21' of the ambient light sensor 2' is 0°, the response is the greatest, and the reading of the ambient light sensor 2' is the greatest. As the deviation angle between the incident light source and the normal direction of the light detection surface 21' of the ambient light sensor 2' increases, the reading of the ambient light sensor 2' decreases. Typically, the angle corresponding to a response of 0.5, that is, half the reading of the ambient light sensor 2' when the incident light source is directly above the light detection surface 21', is defined as the field of view (FOV), which is generally [-45°, +45°]. The field of view (FOV) is small. When the light source comes from the side, the reading of the ambient light sensor 2' drops significantly, and it may even be unable to detect in low light. This can affect the accuracy of detecting the intensity of ambient light, thereby affecting the screen brightness adjustment and making it difficult to meet the screen brightness adjustment requirements in low light environments.

[0115] In view of this, embodiments of this application provide a display module to expand the equivalent field of view of the ambient light sensor, improve the overall ambient light perception field of view of the electronic device, and enhance the accuracy of detecting the light intensity value of ambient light. This display module can be applied to electronic devices, including mobile phones, tablets, desktop computers, laptops, handheld computers, ultra-mobile personal computers (UMPCs), netbooks, as well as cellular phones, personal digital assistants (PDAs), augmented reality (AR) devices, virtual reality (VR) devices, artificial intelligence (AI) devices, wearable devices, in-vehicle devices, smart home devices, supercomputing servers, smart city devices, and other electronic products. Embodiments of this application do not impose any special limitations on the specific type of electronic device.

[0116] For ease of explanation, the following description uses a mobile phone as an example. The electronic device of this application will be described below with specific embodiments.

[0117] Please refer to Figure 3, which is a schematic diagram of the structure of the electronic device provided in this application in a specific embodiment. As shown in Figure 3, the electronic device 100 may include a display module 10 and a housing 30. The display module 10 is mounted on the housing 30, and together with the housing 30, they can form an installation space for mounting a motherboard, battery, camera module, and other electronic devices.

[0118] The display module 10 may include a liquid crystal display (LCD), an organic light-emitting diode (OLED) display panel, or other display panels for displaying images. The housing 30 may consist of a middle frame and a back cover. The middle frame supports the entire device and may be made of materials such as metal, ceramic, glass, or plastic. The back cover may also be made of materials such as metal, ceramic, glass, or plastic. The middle frame and back cover may be molded separately and fixed together by welding, snap-fitting, or bonding to form the housing 30.

[0119] Please refer to Figure 4, which is a schematic diagram of the structure of the display module provided in this application in a specific embodiment.

[0120] As shown in Figure 4, the display module 10 includes a screen 1 and an ambient light sensor 2.

[0121] Screen 1 can be used to display images, videos, etc. Screen 1 includes a main body 11 and an outer peripheral part 12, with the outer peripheral part 12 circumferentially connected to the main body 11.

[0122] For example, the main body 1 can be a display area, and the outer peripheral portion 12 can be a non-display area. The ambient light sensor 2 is positioned on the outer peripheral portion 12 to prevent the display light from the screen from affecting the ambient light sensor 2, thus facilitating the accurate detection of the ambient light intensity value by the ambient light sensor 2. For example, both the main body 1 and the outer peripheral portion 12 are display areas to improve the display interface of the screen 1, thereby enhancing the user experience. The specific settings of the screen 1 can be configured according to actual needs and are not limited here.

[0123] In this application, screen 1 can be a flexible screen. Exemplarily, screen 1 can be an active-matrix organic light-emitting diode (AMOLED) display. As a self-emissive display, AMOLED does not require a backlight module (BLM). Therefore, when the substrate of the AMOLED display is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display can be bent. Exemplarily, display panel 1 can also be an organic light-emitting diode (OLED) display, a mini organic light-emitting diode (MLED) display, a micro organic light-emitting diode (MOLED) display, a quantum dot light-emitting diode (QLED) display, etc., without limitation.

[0124] The ambient light sensor 2 is used to detect the light intensity value of the ambient light in the user's environment, and at least a portion of the ambient light sensor 2 is disposed in the outer peripheral portion 12.

[0125] Please refer to Figure 5, which is a cross-sectional view along the AA direction in Figure 4.

[0126] As shown in Figure 5, the ambient light sensor 2 has a light detection surface 21, which has an angle with one side surface of the screen 1 in the thickness direction Z of the display module 10.

[0127] In this embodiment, as shown in Figure 5, since the light detection surface 21 and the screen 1 have an angle on one side of the display module 10 in the thickness direction Z, that is, the light detection surface 21 is tilted relative to the main body 11, the normal direction of the light detection surface 21 is also offset relative to the normal direction of the screen 1. This causes the field of view (FOV) of the ambient light sensor 2 to also deflect outwards along with the light detection surface 21 relative to the main body 11. Therefore, without changing the FOV of a single ambient light sensor 2, light sources from the side can more easily illuminate the FOV and be detected by the ambient light sensor 2, thus improving the ambient light sensor 2's ability to perceive light sources from the side. This expands the overall ambient light perception field of view of the electronic device and improves the accuracy of detecting the ambient light intensity value. Furthermore, the electronic device can also use this to more precisely adjust the brightness of the screen 10, meeting the screen brightness adjustment needs in low-light environments and avoiding problems such as the screen 10 being too dark or too bright. This makes the brightness of the screen 10 more suitable for the user's eye needs and improves the user experience.

[0128] As shown in Figure 5, in this embodiment of the application, the light detection surface 21 of the ambient light sensor 2 faces the display side 13 of the screen 10, that is, the light detection surface 21 of the ambient light sensor 2 faces the outside of the screen 10, so that the ambient light sensor 2 can directly detect the ambient light. The structure is simple and it is convenient to set up and install multiple ambient light sensors 2.

[0129] As shown in Figures 4 and 5, the display module 10 includes multiple ambient light sensors 2, which are spaced apart on the outer periphery 12. This expands the equivalent field of view (FOV) of the multiple ambient light sensors 2, further increasing the overall ambient light perception FOV of the electronic device and improving its perception of ambient light in environments with side or weak light sources. The spaced arrangement of the multiple ambient light sensors 2 reduces the number of sensors required on the screen 1 and avoids overlap of the FOVs of adjacent sensors, ensuring detection accuracy while reducing manufacturing costs. Furthermore, the multiple ambient light sensors 2 can simultaneously detect ambient light, allowing the electronic device to combine the light intensity measurements from each sensor to obtain a more accurate ambient light intensity value, reducing detection errors.

[0130] Figure 2 shows the response curves of each ambient light sensor 2 to incident light at different angles. As mentioned earlier, in related technologies, a response of 0.5, i.e., the angle corresponding to half of the maximum light intensity measurement value of a single ambient light sensor 2 as the angle of the incident light source changes, is typically defined as the field of view. Based on this, the angle corresponding to half of the maximum equivalent detection value of multiple ambient light sensors 2 can be defined as the equivalent field of view of multiple ambient light sensors 2. The equivalent detection value refers to the equivalent measurement result obtained by combining the light intensity measurements of multiple ambient light sensors 2; this equivalent measurement value is the ambient light intensity value detected by multiple ambient light sensors 2.

[0131] Please refer to Figure 6, which is an equivalent curve diagram showing the response of multiple ambient light sensors in the display module provided in this application to incident light at different angles. In Figure 6, the horizontal axis represents the angle between the incident light source and the normal direction of the equivalent light detection surface, and the vertical axis represents the equivalent response of the multiple ambient light sensors 2 to the incident light source. The greater the response, the greater the equivalent detection value of the multiple ambient light sensors 2 for the ambient light.

[0132] As shown in Figure 6, in the display module 10 provided in this application, the angle corresponding to half of the maximum equivalent detection value of the incident light source at different angles by the multiple ambient light sensors 2 is relatively large. That is, the equivalent field of view (FOV) of the multiple ambient light sensors 2 of the display module is relatively large, thereby improving the perception capability of light sources from the side and expanding the overall ambient light perception field of view of the electronic device. This improves the detection accuracy of the ambient light intensity value, allowing the electronic device to adjust the brightness of the screen 10 more precisely, meeting the screen brightness adjustment needs in low-light environments, avoiding problems such as the screen 10 being too dark or too bright, making the brightness of the screen 10 more in line with the user's eye needs, and improving the user experience.

[0133] Please refer to Figure 7, which is a diagram showing the positional relationship between the display module and the light source provided in this application.

[0134] As shown in Figure 7, since the light detection surface 21 is tilted relative to the surface of the screen 1, i.e., it has an angle, the field of view (FOV) of the ambient light sensor 2 is deflected. Therefore, when the light source 200 is located to the side of the electronic device, the angle between the light source and the normal direction of the light detection surface 21 is different for the ambient light sensor 2 at different positions. As a result, the response of the ambient light sensor 2 at different positions to the light source located to the side is also different, and the detected light intensity measurement value will have a large difference.

[0135] For example, in the specific embodiment shown in FIG7, when the light source 200 is located to the side, the ambient light sensor 2, which is closer to the light source 200, detects more light within its field of view (FOV), has a smaller angle between the normal direction of its light detection surface 21 and the light ray, exhibits a higher response, and detects a larger light intensity measurement value. Conversely, the ambient light sensor 2, which is farther from the light source 200, detects less light within its FOV, has a larger angle between the normal direction of its light detection surface 21 and the light ray, exhibits a lower response, and detects a smaller light intensity measurement value. Therefore, it can be determined that the light source 200 is closer to the ambient light sensor 2, which has a larger measured light intensity value, thus indicating that the light source 200 is located on the side of the ambient light sensor 2 on the electronic device that has the larger measured light intensity value.

[0136] Therefore, by comparing and analyzing the light intensity measurements of the ambient light sensors 2 at various locations, the relative position of the light source with respect to the ambient light sensor 2 can be obtained. This allows the approximate direction of the light source relative to the electronic device, enabling the electronic device to combine the ambient light intensity value and the direction of the light source to make more precise adjustments to the screen 10 of the electronic device, thereby improving the user experience.

[0137] As shown in Figure 7, in one specific embodiment, the angle between the light detection surface 21 and one side surface of the screen 1 in the thickness direction Z of the display module 10 is α, where 0° < α ≤ 90°. For example, the angle α between the light detection surface 21 and the upper surface of the screen 1 can be 5°, 10°, 15°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, etc. Of course, the angle α can also be other values ​​within the above range. It can be set according to actual needs and is not limited here.

[0138] If the included angle α = 0°, the equivalent field of view (FOV) of multiple ambient light sensors 2 is the same as that of a single ambient light sensor 2. The accuracy of the electronic device in detecting light or weak light sources remains low, and its ability to perceive ambient light cannot be improved. However, if the included angle α is too large, for example, α > 90°, part of the FOV of the ambient light sensor 2 tends to face the side of the screen 1 away from the light-emitting side 13, meaning part of the FOV of the ambient light sensor 2 tends to face the back of the electronic device, resulting in wasted field of view. Consequently, the projected area of ​​the light detection surface 21 of the ambient light sensor 2 in the direction perpendicular to the thickness direction Z becomes too large. This not only makes it easy for the casing of the electronic device to block the light detection surface 21 of the ambient light sensor 2, but also easily blocks the FOV of the ambient light sensor 2, affecting its perception of ambient light and reducing the accuracy of detecting the ambient light intensity value.

[0139] In this embodiment, as shown in FIG7, when the angle α between the light detection surface 21 and one side surface of the screen 1 in the thickness direction of the display module satisfies 0°<α≤90°, the field of view (FOV) of the ambient light sensor 2 faces the front of the electronic device, that is, the field of view (FOV) of the ambient light sensor 2 faces the display side 13 of the screen 1, and can avoid the casing of the electronic device from blocking the field of view (FOV) of the ambient light sensor 2, thereby effectively expanding the equivalent field of view of multiple ambient light sensors 2 and improving the accuracy of detecting the light intensity value of ambient light.

[0140] As shown in Figure 7, in one specific embodiment, multiple ambient light sensors 2 are disposed within the screen 1, thereby integrating the ambient light sensors 2 with the screen 1, improving the integration of the display module 10. Furthermore, the multiple ambient light sensors 2 can be installed along with other sensors and electronic devices integrated within the screen 1 during the screen 1 manufacturing process, reducing the installation difficulty of the multiple ambient light sensors 2, improving the manufacturing efficiency of the electronic device, and saving costs. In addition, by disposing of the ambient light sensors 2 within the screen 1, the internal circuitry of the screen 1 can be reused to achieve communication with the processor within the electronic device, further improving the integration of the display module 10, and without occupying the internal space of the electronic device's casing, thus further improving the utilization rate of the internal space of the electronic device.

[0141] Screen 1 has a multi-layered structure, including a glass cover layer, a touch layer, and a display panel stacked together. The glass cover layer primarily serves a protective function, preventing external physical damage. It is typically made of wear-resistant, high-strength, and light-transmitting materials such as glass or plastic, and no restrictions are placed here. The touch layer is usually located between the display panel and the glass cover layer, responsible for receiving user touch operations. The touch layer is usually composed of multiple thin films, including a touch sensor layer, a protective layer, and a conductive layer. When a finger or stylus touches the glass cover, the sensor layer detects a signal, which is transmitted to the processor of the electronic device, thereby enabling operation of the electronic device. The display panel is used to display images and text and can be made of a flexible material. Of course, screen 1 can also include other film layer structures, and can also include other electronic components such as cameras, fingerprint recognition sensors, and proximity sensors to improve the integration of the electronic device and enrich its functionality, and no restrictions are placed here.

[0142] The multiple ambient light sensors 2 in this application can be disposed between any two layers of the screen 1, so that the multiple ambient light sensors 2 can be integrated with the screen 1 as a whole. For example, the multiple ambient light sensors 2 can be disposed between the glass cover layer and the touch layer; for example, the multiple ambient light sensors 2 can be disposed between the touch layer and the display panel. Of course, the multiple ambient light sensors 2 can also be disposed between other film layers of the screen 1, and the specific configuration can be determined according to actual needs, without limitation.

[0143] For example, multiple ambient light sensors 2 can also be disposed within any one of the film layers in the screen 1. For instance, the ambient light sensor 2 can be disposed within the display panel or within the touch layer. The specific arrangement can be determined according to actual needs, as long as the ambient light sensor 2 is located inside the screen 1. No restrictions are imposed here.

[0144] For example, the ambient light sensor can also be formed as a separate film structure in the display module.

[0145] For example, the display module 10 may further include an ambient light detection unit, and multiple ambient light sensors 2 may be integrated into this ambient light detection unit to further improve the integration of the display module 10. Multiple ambient light sensors 2 may be integrated into any of the aforementioned film layers as ambient light sensor units, without limitation.

[0146] Please refer to Figure 8, which is a schematic diagram of the structure of the display module provided in this application in another specific embodiment.

[0147] As shown in Figure 8, in another specific embodiment, along the thickness direction Z of the display module 10, the ambient light sensor 2 is disposed on the side of the screen 1 away from the display side 13, that is, the ambient light sensor 2 can be disposed below the screen 1.

[0148] For example, the ambient light sensor 2 can be integrated with the screen 1 to facilitate the overall installation of the display component 10. Alternatively, the ambient light sensor 2 and the screen 1 can be fabricated separately and then connected by bonding or other methods. When the ambient light sensor is integrated as an ambient light detection unit, it can also be integrated into various film layers of the screen 1 through integrated circuit control. For example, the ambient light sensor 2 can also be installed on other components located in the space below the screen 1 within the electronic device to enhance the design freedom of the electronic device. The specific configuration can be tailored to actual needs and is not limited here.

[0149] When the ambient light sensor 2 is located below the screen 1, the circuitry within the screen 1 can be reused to communicate with the processor within the electronic device, thereby improving the integration of the display module 10. Of course, the ambient light sensor 2 can also utilize other circuitry within the electronic device to communicate with the processor, which is not restricted here.

[0150] As shown in FIG8, in one specific embodiment, at least a portion of the outer peripheral portion 12 is bent relative to the main body portion 11 to form a bending region 121, and at least a portion of the ambient light sensor 2 is disposed in the bending region 121.

[0151] In this embodiment, as shown in FIG8, at least a portion of the ambient light sensor 2 is disposed in the bending area 121, so that the ambient light sensor 2 can utilize the natural bending of the outer peripheral portion 12 to achieve an inclined arrangement of its light detection surface 21 relative to the main body portion 11, thereby creating an angle between the light detection surface 21 and the surface of the main body portion 11, which facilitates the installation of the ambient light sensor 2 and eliminates the need for additional support blocks or other auxiliary installation components, further reducing the structural complexity of the electronic device, facilitating the manufacture of the electronic device, and saving costs.

[0152] The bending area 121 can be formed by bending one or more layers of structure in the screen 1 on the outer periphery 12. Of course, it can also be formed in other ways, which are not limited here.

[0153] In another specific embodiment, as shown in FIG4, the outer peripheral portion 12 and the main body portion 11 can also be located on the same plane, thereby reducing the manufacturing difficulty of the screen 1 and increasing the design freedom of the display module 10. As long as there is an angle between the light detection surface 21 of the ambient light sensor 2 located at least partially on the outer peripheral portion 12 and the surface of the main body portion 11, no limitation is imposed here.

[0154] Please refer to Figure 9, which is a structural block diagram of a display module provided in this application.

[0155] As shown in Figure 9, the display module 10 also includes a proximity light sensor 3, which is used to detect the distance between the ambient light sensor 2 and the obstruction and to emit a first detection signal.

[0156] When multiple ambient light sensors 2 detect ambient light simultaneously, the processor of the electronic device receives the light intensity detection values ​​from multiple ambient light sensors 2. However, since at least a portion of the multiple ambient light sensors 2 are located on the outer periphery 12 of the screen 1, during user operation, some ambient light sensors 2 may be blocked by objects such as people, clothing, supports, walls, and cabinets. The detection values ​​of the blocked ambient light sensors 2 are obviously abnormal. If these abnormal measurement values ​​are included in the calculation, the accuracy of the ambient light intensity detection value will be easily reduced.

[0157] In this embodiment, the electronic device can determine whether the ambient light sensor 2 is obstructed based on the first detection signal, thereby eliminating abnormal values ​​from multiple light intensity measurements and selecting the light intensity measurement value of the unobstructed ambient light sensor 2, i.e., the first light intensity measurement value. This reduces the impact of obstructions on the accuracy of ambient light detection and improves the accuracy of detecting ambient light intensity values. This method of determining the obstruction state of the ambient light sensor 2 is simple and reliable, facilitating accurate determination of the obstruction state of the ambient light sensor 2, reducing the complexity of screen brightness adjustment methods, and improving the efficiency and accuracy of screen brightness adjustment.

[0158] Specifically, the ambient light sensor can be determined to be blocked if the distance between it and the obstruction is less than a first threshold. If the distance is less than the first threshold, the ambient light sensor is determined to be blocked. If the distance is greater than or equal to the first threshold, the ambient light sensor is determined to be unblocked.

[0159] Furthermore, as shown in Figure 9, the display module 10 may also include a touch sensor 4, which can be used to detect the contact position of an obstruction on the screen 1 and emit a second detection signal.

[0160] Specifically, when a human body or a stylus or other obstruction touches the screen 1, the touch sensor 4 detects the change in capacitance caused by the contact and sends out a second detection signal. These signals are transmitted to the processor of the electronic device. By comparing the contact position with the position of the ambient light sensor 2, the occlusion status of the ambient light sensor 2 can be determined. For example, if the contact position and the position of the ambient light sensor 2 overlap at least partially, it can be determined that the ambient light sensor 2 is occluded. If the contact position and the position of the ambient light sensor 2 do not overlap, it can be determined that the ambient light sensor 2 is not occluded.

[0161] Therefore, the electronic device can further determine whether the ambient light sensor 2 is obstructed based on the second detection signal, thereby eliminating abnormal values ​​from multiple light intensity measurements and selecting the light intensity measurement value of the unobstructed ambient light sensor 2, i.e., the first light intensity measurement value. This reduces the impact of obstructions on the accuracy of ambient light detection and improves the accuracy of detecting ambient light intensity values. This method of determining the obstruction state of the ambient light sensor 2 is simple and reliable, further improving the accuracy of determining the obstruction state of the ambient light sensor 2 and further improving the efficiency and accuracy of screen brightness adjustment.

[0162] Of course, other methods can also be used to determine the occlusion status of ambient light sensor 2, and no restrictions are imposed here.

[0163] It should be noted that the various sensors in this application, such as ambient light sensor 2, proximity light sensor 3, or touch sensor 4, can be independent devices or sensing units integrated into various film layers in the display module 10. The specific settings can be made according to actual needs, and no restrictions are imposed here.

[0164] Please refer to Figure 10, which is a structural block diagram of an electronic device provided in this application. As shown in Figure 10, the electronic device 100 further includes a processor 20, which is electrically connected to the display module 10. The processor 20 is used to acquire the light intensity measurement values ​​of multiple ambient light sensors 2 in the display module 10, as well as the normal direction of the light detection surface 21 of the multiple ambient light sensors 2 in space, and adjust the screen brightness of the display module 1 according to the multiple light intensity measurement values ​​and the multiple normal directions.

[0165] As shown in Figure 8, the ambient light sensor 2 has a light detection surface 21. The direction perpendicular to its light detection surface 21 is the normal direction mentioned above. As shown in Figure 4, since the positions of the multiple ambient light sensors 2 on the screen 1 are different, the positions of the light detection surfaces 21 of the multiple ambient light sensors 2 in space are also different, and the positions of the normal directions of each ambient light sensor 2 in space are also different. Therefore, the electronic device can determine the position of the corresponding ambient light sensor 2 based on the normal direction, and then determine the position of the light source relative to the ambient light sensor 2 based on the light intensity measurement value of each ambient light sensor 2, thereby determining the direction of the light source relative to the electronic device, so as to more accurately adjust the brightness of the screen 1. Of course, the positions of each ambient light sensor 2 can also be determined by other methods, which are not limited here.

[0166] In this application, multiple ambient light sensors 2 can simultaneously detect ambient light. By comparing and analyzing the light intensity measurements of each ambient light sensor 2, the processor can obtain a more accurate ambient light intensity value. Simultaneously, by combining the positional information such as the normal direction of the light detection surface 21 of each ambient light sensor 2 in space, the direction of the light source relative to the electronic device can be obtained. This allows the electronic device to more precisely adjust its screen 10 based on the ambient light intensity value and the direction of the light source, thus improving the user experience.

[0167] Specifically, as shown in Figure 10, the processor 20 includes an ambient light calculation module 201 and a screen brightness adjustment module 202. The ambient light calculation module 201 is used to determine the ambient light intensity value based on multiple light intensity measurements, and send the ambient light intensity value and the normal direction of the light detection surface 21 of the multiple ambient light sensors 2 in space to the screen brightness adjustment module 202. The screen brightness adjustment module 202 is used to determine the target screen brightness of the screen 1 based on the ambient light intensity value, and to determine the screen brightness adjustment speed based on the normal direction of the light detection surface 21 of the multiple ambient light sensors 2 in space, and to adjust the brightness of the screen 1 based on the target screen brightness and the adjustment speed.

[0168] The direction of the light source relative to the electronic device can be determined based on the normal direction of the light detection surface 21 of multiple ambient light sensors 2 in space. Furthermore, the speed of change of the direction of the light source relative to the electronic device can be determined based on the normal direction information of multiple ambient light sensors 2 at different times. This allows the electronic device to determine the adjustment speed and adjust the brightness of the screen 1 accordingly, thus avoiding the phenomenon of the screen 1 flickering between bright and dim.

[0169] In this embodiment, the adjustment speed of screen brightness can be determined by the normal direction of the light detection surface 21 of the ambient light sensor 2 in space, thereby avoiding the phenomenon of screen 1 flickering between bright and dim, further improving the control accuracy of screen brightness adjustment, meeting the user's eye needs under different light sources, and improving the user experience.

[0170] Please refer to Figure 11, which is a structural block diagram of the electronic device provided in this application in another specific embodiment.

[0171] As shown in Figure 11, the electronic device also includes a driver chip 5, which is used to convert the analog light signal collected by the ambient light sensor 2 into a digital signal and transmit it to the processor 20.

[0172] The driver chip 5 can be connected to the multi-channel ambient light sensor 2 and supports the processing of multiple signals to improve signal conversion efficiency.

[0173] For example, the driver chip 5 can be integrated into the screen 1 together with the ambient light sensor 5, thereby further improving the integration of the display module. For example, the driver chip 5 can also be a separate chip housed in the casing of the electronic device; the specific configuration can be determined according to actual needs and is not limited here.

[0174] Please refer to Figure 12, which is a flowchart of the screen brightness adjustment method provided in this application in a specific embodiment.

[0175] This application also provides a screen brightness adjustment method, the adjustment method comprising:

[0176] Step S1: Obtain the light intensity measurement value X(i) of multiple ambient light sensors 2, and the normal direction of the light detection surface 21 of multiple ambient light sensors 2 in space.

[0177] In this step, the processor 20 of the electronic device 100 can periodically read the light intensity measurement value X(i) of each ambient light sensor 2. For example, it can read the light intensity measurement value X(i) of the ambient light sensor 2 every 100ms, 200ms, 300ms, and 400ms to adjust the brightness of the screen 1 in a timely manner according to the real-time ambient light intensity. Here, i represents the number of the ambient light sensor 2. When there are n ambient light sensors 2, i = 1, 2, 3...n. At the same time, as shown in Figure 8, the ambient light sensor 2 has a light detection surface 21. The direction perpendicular to its light detection surface 21 is the normal direction mentioned above. As shown in Figure 4, since the positions of the multiple ambient light sensors 2 on the screen 1 are different, the positions of the light detection surfaces 21 of the multiple ambient light sensors 2 in space are different, and the positions of the normal directions of each ambient light sensor 2 in space are also different. Therefore, the electronic device can determine the position of the corresponding ambient light sensor 2 based on the normal direction, and then determine the position of the light source relative to the ambient light sensor 2 based on the light intensity measurement value of each ambient light sensor 2, thereby determining the direction of the light source relative to the electronic device, so as to adjust the brightness of the screen 1 more accurately.

[0178] Step S2: Determine the target screen brightness B and adjustment speed V based on multiple light intensity measurements X(i) and multiple normal directions.

[0179] In this step, the processor 20 obtains a more accurate ambient light intensity value X by comparing and analyzing multiple light intensity measurements X(i). avg And based on the light intensity value X avg The processor 20 calculates the target screen brightness B, which is most suitable for human viewing under the ambient light conditions. It can also analyze multiple normal directions to determine the relative position of the light source with respect to the ambient light sensor 2, thereby determining the positional relationship of the light source with respect to the electronic device 100. Furthermore, based on the normal direction information of multiple ambient light sensors 2 at different times, it can determine the rate of change of the light source's direction relative to the electronic device 100, allowing the electronic device to determine the adjustment speed V accordingly.

[0180] Step S3: Adjust the screen brightness according to the target screen brightness B and the adjustment speed V.

[0181] In this step, the processor 20 uses an adjustment speed V to adjust the screen 1 from the current screen brightness B' to the target screen brightness B to meet the user's needs. The faster the adjustment speed V, the shorter the time it takes for the screen 1 to adjust from the current screen brightness B' to the target screen brightness B; conversely, the slower the adjustment speed V, the longer the time it takes for the screen 1 to adjust from the current screen brightness B' to the target screen brightness B.

[0182] In this embodiment, multiple ambient light sensors 2 can simultaneously detect ambient light, expanding the overall ambient light perception field of view of the electronic device. Furthermore, the electronic device 100 can integrate the light intensity measurements X(i) detected by each ambient light sensor 2 to obtain a more accurate ambient light intensity value X. avg This reduces detection errors, allowing for the accurate calculation of the target screen brightness B. This enables precise adjustment of screen 1's brightness, meeting the needs of low-light environments and preventing issues such as excessively dim or bright screens. The resulting brightness better suits the user's eye requirements, enhancing the user experience. Furthermore, the adjustment speed V of the screen brightness can be determined by the normal direction of the light detection surface 21 of each ambient light sensor 2 in space. This prevents screen 1 from flickering between bright and dim areas, further improving the control precision of screen brightness adjustment and meeting the user's eye requirements under different light sources, thus further enhancing the user experience.

[0183] During the process of adjusting screen 1 from the current screen brightness B' to the target screen brightness B, the screen brightness can be refreshed at regular intervals to gradually adjust the screen brightness from the current screen brightness B' to the target screen brightness B, thereby further avoiding the phenomenon of screen 1 flickering between bright and dim. Specifically, the screen refresh interval can be 50ms, 100ms, 150ms, 200ms, etc., that is, screen 1 can sequentially refresh its brightness every 50ms, 100ms, 150ms, 200ms, etc., which can be set according to actual needs and is not limited here.

[0184] Specifically, the processor 20 includes an ambient light calculation module 201 and a screen brightness adjustment module 202. The ambient light calculation module 201 is used to determine the ambient light intensity value X based on multiple light intensity measurements X(i). avg And the ambient light intensity value X avg The light detection surfaces 21 of the multiple ambient light sensors 2 are sent in the normal direction in space to the screen brightness adjustment module 202. The screen brightness adjustment module 202 is used to determine the target screen brightness B of the screen 1 according to the light intensity value of the ambient light, and to determine the screen brightness adjustment speed V according to the normal direction in space of the light detection surfaces 21 of the multiple ambient light sensors 2, and to adjust the brightness of the screen 1 according to the target screen brightness B and the adjustment speed V.

[0185] In one specific embodiment, step S2, determining the target screen brightness B and adjustment speed V based on multiple light intensity measurements X(i) and multiple normal directions, specifically includes:

[0186] Step S21: Select the effective light intensity measurement value X(k) from multiple light intensity measurement values ​​X(i).

[0187] In this step, by analyzing the light intensity measurement values ​​X(i) obtained from each ambient light sensor 2, abnormal readings are removed, and valid light intensity measurement values ​​X(k) are selected to reduce detection errors. Here, k represents the number of the ambient light sensor 2 corresponding to the valid light intensity measurement value.

[0188] Step S22: Determine the ambient light intensity value X based on the effective light intensity measurement value X(k). avg .

[0189] In this step, the ambient light intensity value X is obtained by calculating the average of each effective light intensity measurement value X(k). avg , that is, X avg =average(X(k)), further reducing detection error.

[0190] Step S23, based on the ambient light intensity value X avg Determine the target screen brightness B.

[0191] In this step, based on the light intensity value X avg Calculate the optimal screen brightness B for human viewing of screen 1 under this ambient light condition. This can be determined based on the ambient light intensity value X. avg The mapping relationship with screen brightness is used to determine the target screen brightness B in the lookup table to improve the processing speed of processor 20.

[0192] When multiple ambient light sensors 2 detect ambient light simultaneously, the processor 20 of the electronic device receives the light intensity detection values ​​from multiple ambient light sensors 2. However, since multiple ambient light sensors 2 are located on the outer periphery 12 of the screen 1, some ambient light sensors 2 may be blocked by objects such as people, clothing, brackets, walls, and cabinets during user operation. The detection values ​​of the blocked ambient light sensors 2 are abnormal. If such abnormal measurement values ​​are included in the calculation, the accuracy of the ambient light intensity detection value will be reduced.

[0193] In this embodiment, by selecting the effective light intensity measurement value X(k) from multiple light intensity measurement values ​​X(i), and calculating the target screen brightness B more accurately based on the effective light intensity measurement value X(k), the detection error is further reduced, thereby enabling more precise adjustment of the brightness of screen 1.

[0194] Further, step S21, selecting the effective light intensity measurement value X(k) from multiple light intensity measurement values ​​X(i), specifically includes:

[0195] Step S211: Determine the occlusion status of ambient light sensor 2.

[0196] In this step, the occlusion status of the ambient light sensor 2 can be determined using auxiliary information such as proximity sensors and touch sensors. Of course, other methods can also be used to determine the occlusion status of the ambient light sensor 2, and this is not a limitation here.

[0197] Step S212: Obtain the light intensity measurement value of the unobstructed ambient light sensor 2. The light intensity measurement value of the unobstructed ambient light sensor 2 is the first light intensity measurement value X(j). Here, j represents the number of the unobstructed ambient light sensor 2.

[0198] In this step, the aforementioned light intensity measurement value X(i) includes the light intensity measurement value measured by the occluded ambient light sensor 2 and the light intensity measurement value measured by the unoccluded ambient light sensor 2. In this step, it is necessary to remove the light intensity measurement value measured by the occluded ambient light sensor 2 and retain the light intensity measurement value measured by the unoccluded ambient light sensor 2. The light intensity measurement value of the unoccluded ambient light sensor 2 is the first light intensity measurement value X(j).

[0199] Step S213: Determine the threshold value X1 based on the first light intensity measurement value X(j).

[0200] In this step, the threshold value X1 can serve as a reference value to filter out valid light intensity measurements X(k). For example, it can be the maximum value X(j) among the first light intensity measurements X(j). max Determine the threshold value X1, i.e., X1 = a*X(j). max Where 'a' is a threshold coefficient, which can be 0.2, 0.3, 0.4, etc., and can be set according to actual needs; no restrictions are imposed here. For example, it can also be the average value X(j) of the first light intensity measurement value X(j). avg Determine the threshold value X1, i.e., X1 = b*X(j). avg b is the threshold coefficient, and a can be 0.3, 0.4, 0.5, etc. The specific value can be set according to actual needs, and there is no restriction here.

[0201] Step S214: Obtain the light intensity measurement value greater than the threshold value X1 from the first light intensity measurement value X(j). The light intensity measurement value greater than the threshold value X1 from the first light intensity measurement value X(j) is the effective light intensity measurement value X(k). Here, k represents the number of the ambient light sensor 2 corresponding to the effective light intensity measurement value.

[0202] In this step, the first light intensity measurement value X(j) is compared with the threshold value X1 in turn. If X(j) > X1, the first light intensity measurement value X(j) is output as the effective light intensity measurement value X(k).

[0203] In this embodiment, by judging the occlusion state of the ambient light sensor 2 and determining the threshold value X1, multiple light intensity measurement values ​​X(i) are screened multiple times. More reliable and effective light intensity measurement values ​​X(k) can be selected for the current environment, thereby further reducing detection errors. Moreover, this method is simple and easy to implement, and can quickly screen multiple light intensity measurement values ​​X(i), improving the efficiency of screen brightness adjustment.

[0204] Further, step S211, determining the occlusion state of the ambient light sensor 2, specifically includes:

[0205] Step S211a: Detect whether the distance S between the ambient light sensor 2 and the obstruction is less than the first threshold Y.

[0206] In this step, the distance S between the ambient light sensor 2 and the obstruction can be detected by setting the proximity light sensor 3, and a first detection signal can be emitted. This allows the processor 20 to compare the distance S between the ambient light sensor 2 and the obstruction with a first threshold Y based on the first detection signal, thereby determining whether the distance S between the ambient light sensor 2 and the obstruction is less than the first threshold Y.

[0207] In this context, the distances between the multiple ambient light sensors 2 and the obstruction are denoted by S(i), where i is the number of the ambient light sensor. By comparing the magnitudes of the multiple distances S(i) with the first threshold Y, the obstruction status of the multiple ambient light sensors 2 can be determined.

[0208] Step S211b: If the distance S is less than the first threshold Y, it is determined that the ambient light sensor 2 is blocked.

[0209] In this step, the distance S is compared with the first threshold Y. If S < Y, it is determined that the ambient light sensor 2 is blocked.

[0210] Step S211c: If the distance S is greater than or equal to the first threshold Y, it is determined that the ambient light sensor 2 is not blocked.

[0211] In this step, the distance S is compared with the first threshold Y. If S≥Y, it is determined that the ambient light sensor 2 is blocked.

[0212] In this embodiment, the electronic device can determine whether the ambient light sensor 2 is obstructed by comparing whether the distance S between the ambient light sensor 2 and the obstruction is less than a first threshold Y. This allows it to eliminate abnormal values ​​from multiple light intensity measurements and filter out the light intensity measurement value of the unobstructed ambient light sensor 2, i.e., the first light intensity measurement value. This reduces the impact of the obstruction on the accuracy of ambient light detection and improves the accuracy of detecting the ambient light intensity value. This method of determining the obstruction state of the ambient light sensor 2 is simple and reliable, facilitates accurate determination of the obstruction state of the ambient light sensor 2, reduces the complexity of the screen brightness adjustment method, and improves the efficiency and accuracy of screen brightness adjustment.

[0213] The first threshold Y can be 1mm, 2mm, 3mm, 4mm, 5mm, etc., and can be set according to actual needs. No restrictions are imposed here.

[0214] Further, step S211, determining the occlusion state of the ambient light sensor 2, specifically includes:

[0215] In step S211d, the touch sensor 4 sends out a second detection signal based on the capacitance change generated when it comes into contact with the obstruction.

[0216] In this step, when a human body or a stylus or other obstruction comes into contact with the screen 1, the touch sensor 4 detects the change in capacitance caused by the contact and sends out a second detection signal. These signals are then transmitted to the processor 20 of the electronic device.

[0217] Step S211e: Determine the contact position of the obstruction on the screen 1 based on the second detection signal.

[0218] In this step, the processor 20 can determine the contact position of the obstruction on the screen 1 based on the second detection signal.

[0219] Step S211f: Determine the occlusion state of the ambient light sensor 2 based on the contact position.

[0220] In this step, the occlusion status of the ambient light sensor 2 can be determined by comparing the contact position with the position of the ambient light sensor 2. For example, if the contact position and the position of the ambient light sensor 2 at least partially overlap, it can be determined that the ambient light sensor 2 is occluded; if the contact position and the position of the ambient light sensor 2 do not overlap, it can be determined that the ambient light sensor 2 is not occluded.

[0221] In this embodiment, the electronic device can determine whether the ambient light sensor 2 is obstructed based on the second detection signal. This allows for the elimination of abnormal values ​​from multiple light intensity measurements, filtering out the light intensity measurement value of the unobstructed ambient light sensor 2, i.e., the first light intensity measurement value. This reduces the impact of obstructions on the accuracy of ambient light detection and improves the accuracy of detecting ambient light intensity values. This method of determining the obstruction state of the ambient light sensor 2 is simple and reliable, further improving the accuracy of determining the obstruction state of the ambient light sensor 2 and further enhancing the efficiency and accuracy of screen brightness adjustment.

[0222] Of course, the electronic device 100 can also determine the occlusion status of the ambient light sensor 2 in other ways. The specific settings can be made according to actual needs, and no restrictions are imposed here.

[0223] In one specific embodiment, after selecting the valid light intensity measurement value X(k) from the plurality of light intensity measurement values ​​X(i) in step S21, the method further includes:

[0224] Step S24: Obtain the normal direction in space for each ambient light sensor 2 corresponding to the effective light intensity measurement value X(k), which is the first normal direction. Here, k represents the number of the ambient light sensor 2 corresponding to the effective light intensity measurement value X(k).

[0225] In this step, the normal direction of each ambient light sensor 2 corresponding to the effective light intensity measurement value X(k) is obtained from the normal directions corresponding to the multiple ambient light sensors 2, that is, the first normal direction. The position of the ambient light sensor 2 numbered k on the electronic device 100 can be determined by the first normal direction, thereby determining the positional relationship of the light source relative to the ambient light sensor 2 numbered k, and then determining the direction of the light source relative to the electronic device.

[0226] As mentioned earlier, as shown in Figure 7, the angle between the light source and the normal direction of the light detection surface 21 varies for ambient light sensors 2 at different positions. This results in different response levels of ambient light sensors 2 to side light sources. When the light source 200 is located to the side, ambient light sensors 2 closer to the light source 200 detect more light within their field of view (FOV), have a smaller angle between the normal direction of their light detection surface 21 and the light rays, exhibit a higher response, and receive a larger measured light intensity. Conversely, ambient light sensors 2 farther from the light source 200 detect less light within their FOV, have a larger angle between the normal direction of their light detection surface 21 and the light rays, exhibit a lower response, and receive a smaller measured light intensity. Therefore, the ambient light sensor 2 with the effective light intensity measurement X(k) corresponding to the number k is closer to the light source, thus indicating that the light source is located on the side of ambient light sensor 2 with the number k on the electronic device.

[0227] Step S25: Determine the normal direction based on the first normal direction.

[0228] In this step, the sum normal direction is the resultant direction of multiple first normal directions. When there is only one first normal direction, the sum normal direction is the same as the first normal direction.

[0229] Step S26: Obtain the sum and normal directions at multiple time points.

[0230] In this step, the sum and normal directions at multiple moments can be obtained through the aforementioned steps.

[0231] Step S27: Determine the change in normal direction based on the sum of normal directions at two adjacent moments.

[0232] In this step, if the environment is one where the direction of the ambient light source relative to the electronic device is constantly changing, such as walking under a street lamp, the direction of the light source relative to the electronic device 100 is different at two adjacent moments. Therefore, the ambient light sensors 2 corresponding to the effective light intensity measurement values ​​X(k) at two adjacent moments are different. The normal directions of each ambient light sensor 2 corresponding to the effective light intensity measurement value X(k) in space are different, that is, the first normal direction is different, and the calculated sum normal directions are also different, resulting in a change in the normal direction. The change in the normal direction can be obtained by comparing and subtracting the sum normal directions at two adjacent moments t1 and t2, thereby determining the rate of change of the direction of the ambient light source relative to the electronic device. Specifically, the larger the change in the normal direction, the faster the change of the direction of the ambient light source relative to the electronic device 100; the smaller the change in the normal direction, the slower the change of the direction of the ambient light source relative to the electronic device 100.

[0233] Step S28: Determine the adjustment speed V based on the change in the normal direction.

[0234] In this step, the rate of change of the direction of the light source relative to the electronic device between two adjacent moments t1 and t2 can be determined based on the change in the normal direction. This allows the processor 20 to determine the corresponding adjustment speed V based on the change in the normal direction, so that the electronic device can adjust the screen brightness in different ways under different light source environments.

[0235] In this embodiment, by analyzing the normal direction of the light detection surface 21 of multiple ambient light sensors 2 in space, the direction of the light source relative to the electronic device can be determined. Thus, the electronic device 100 can calculate the change in normal direction based on the sum and normal directions of multiple ambient light sensors 2 at different times, thereby determining the rate of change of the direction of the light source relative to the electronic device 100. Based on this, the electronic device 100 can determine the adjustment speed V, so that the electronic device 100 can use different adjustment speeds V to adjust the brightness of the screen 1 under different ambient light sources, avoiding the phenomenon of the screen 1 flickering between bright and dim, and improving the user experience.

[0236] Further, step 28, determining the adjustment speed based on the change in the normal direction, specifically includes:

[0237] Step S281: Compare the change in normal direction with a preset threshold.

[0238] In this step, the preset threshold can be used as a reference value to determine the magnitude of the change in the normal direction, so as to determine how fast the direction of the ambient light source changes relative to the electronic device 100.

[0239] Step S282: If the change in the normal direction is greater than or equal to a preset threshold, determine the adjustment speed V as the first speed V1.

[0240] In this step, the change in the normal direction is compared with a preset threshold. If the change in the normal direction is greater than or equal to the preset threshold, the direction of the light source relative to the electronic device 100 changes faster. V = V1 is then determined, and the screen brightness is adjusted using the first speed V1.

[0241] Step S283: If the change in the normal direction is less than the preset threshold, determine the adjustment speed V as the second speed V2.

[0242] In this step, the change in the normal direction is compared with a preset threshold. If the change in the normal direction is less than the preset threshold, the direction of the light source relative to the electronic device 100 changes slowly. V = V2 is then determined, and the screen brightness is adjusted using the second speed V2.

[0243] In this embodiment, the method is simple and reliable, improves the accuracy of screen brightness adjustment, meets the eye needs of users using electronic devices in different environments, avoids the phenomenon of screen 1 flickering between bright and dim, and improves the user experience.

[0244] The size of the preset threshold can be set according to actual needs, and there are no restrictions here.

[0245] Furthermore, the first speed V1 is less than the second speed V2, i.e., V1 < V2. This allows the electronic device 100 to adjust the screen brightness at a slower speed when the change in the normal direction is greater than or equal to a preset threshold, even in environments where the direction of the light source relative to the electronic device 100 changes rapidly. This prevents the screen 1 from flickering between bright and dark, which would affect the user experience. Conversely, the electronic device 100 can adjust the screen brightness at a faster speed when the direction of the light source relative to the electronic device 100 changes slowly, i.e., when the change in the normal direction is less than a preset threshold. This allows the screen 1 to quickly adjust from the current screen brightness B' to the target screen brightness B suitable for the user, promptly meeting the user's eye needs and improving the user experience.

[0246] Of course, in addition to setting the above two speed settings, the electronic device 100 can also set three speed settings, four speed settings, etc., such as third speed V3, fourth speed V4, etc. The specific settings can be made according to actual needs, and there are no restrictions here.
