Description

Display screen adjusting method and electronic equipment

Technical Field

The embodiment of the application relates to the technical field of terminals, in particular to a display screen adjusting method and electronic equipment.

Background

When a user uses electronic equipment such as a mobile phone, a tablet and the like, whether the backlight brightness and the color temperature displayed by a display screen of the electronic equipment are accurately regulated directly influences the comfort level of eyes. Generally, the electronic device can adjust the brightness and display color of its display screen according to the light intensity of the surrounding environment, so the electronic device needs to detect the current ambient light. A module in an electronic device having this function is called an ambient light detection module. The electronic equipment can adjust the backlight brightness and the color temperature displayed by the display screen according to the ambient light parameters reported by the ambient light detection module.

In an electronic device, an ambient light detection module includes a light intake path and an ambient light sensor. The performance of an ambient light sensor can be expressed by a field of view (FOV), which describes the case where the output value of the ambient light sensor decays with angle, and typically, an angle at which the output value of the ambient light sensor decays to half is used as the field of view of the ambient light sensor. In general, a larger field angle indicates a better field of view of the ambient light sensor and better adaptability.

Currently, electronic devices typically place an ambient light sensor in a position in front of a display screen. The layout structure of the light inlet path of the ambient light sensor is also various due to the influence of the layout of the display screen of the electronic device, for example, the electronic device adopts a layout mode such as a full screen. When the layout structure of the ambient light sensor and the light inlet channel in the electronic equipment is poor, the influence of different degrees is brought to the view angle, and then the normal adjustment of the backlight brightness and the color temperature of the display screen of the electronic equipment is influenced.

Disclosure of Invention

The display screen adjusting method and the electronic device provided by the embodiment of the application are used for solving the problem that the adjustment of the backlight brightness, the color temperature and the like of the display screen of the electronic device is inaccurate due to the influence of the performance of an ambient light sensor in the prior art.

In order to achieve the above purpose, the application adopts the following technical scheme:

in a first aspect, a method for adjusting a display screen is provided, where the method is applied to an electronic device, and the method includes: the electronic equipment determines the current equipment gesture; the electronic equipment acquires first ambient light data output by an ambient light sensor; the electronic equipment determines second ambient light data according to the equipment gesture and the first ambient light data; and the electronic equipment adjusts the display screen according to the second ambient light data.

According to the display screen adjusting method, the first ambient light data output by the ambient light sensor is compensated according to the current equipment posture of the electronic equipment, the influence on the visual angle performance of the ambient light sensor caused by the reasons of layout, architecture and the like can be made up, the response curve formed based on the compensated second ambient light data approximates to the response curve formed by the ambient light data output by the ambient light sensor with stronger visual angle performance, the purpose of enhancing the visual angle performance of the ambient light sensor is achieved, the accuracy of the ambient light data reported to the system is improved, the accuracy of the electronic equipment for adjusting the backlight brightness, color temperature and other parameters of the display screen based on the compensated second ambient light data is facilitated, and the adjusted display screen is ensured to be more suitable for human eyes to watch.

With reference to the first aspect, in some possible implementations, the determining, by the electronic device, the current device pose may be implemented based on a pose sensor in the electronic device. Specifically, the electronic device may determine a current device posture according to posture data by reading the posture data output by the posture sensor. Among other things, the gesture sensors in the electronic device may include any one or more of the following sensors: acceleration sensor, magnetic sensor, gyroscope; wherein the magnetic sensor comprises a magnetometer.

It can be appreciated that the electronic device may determine the current device gesture using any gesture data output by any gesture sensor, or may determine the current device gesture using any gesture data output by any of a plurality of gesture sensors.

The electronic device may read data output by the acceleration sensor, determine a current device posture according to the data output by the acceleration sensor, read data output by the magnetic sensor or the gyroscope, determine the current device posture according to the data output by the magnetic sensor or the gyroscope, and read data output by the acceleration sensor and the magnetic sensor simultaneously, and determine the current device posture according to the data output by the two posture sensors.

With reference to the first aspect and the foregoing implementation manner, in some possible implementation manners, each gesture sensor may have a corresponding weight value. When the electronic equipment determines the current equipment gesture according to gesture data output by a plurality of gesture sensors, the equipment gesture can be calculated by adopting the gesture data output by each gesture sensor, and then the equipment gesture calculated by each gesture sensor is fused based on the weight value, so that the fused equipment gesture is obtained.

For example, the electronic device may calculate the current device pose using pose data output by the acceleration sensor and the magnetic sensor, respectively. In this way, the electronic device may obtain two different resulting device poses. Then, the electronic device can fuse the device gestures of the two different results, and the fused result is used as the current device gesture of the electronic device.

With reference to the first aspect and the foregoing implementation manner, in some possible implementation manners, the determining, by the electronic device, the second ambient light data according to the device gesture and the first ambient light data may mean that the electronic device compensates the first ambient light data according to the device gesture, so as to obtain compensated second ambient light data. The process specifically may include: the electronic equipment acquires a pre-generated compensation function; and compensating the first ambient light data according to the equipment posture and the compensation function to obtain second ambient light data.

With reference to the first aspect and the foregoing implementation manner, in some possible implementation manners, the electronic device may generate the compensation function in advance by adopting the following steps: the electronic device records test data output by the ambient light sensor under test conditions, wherein the test data can comprise output values of the ambient light sensor corresponding to different device attitudes. Then, the electronic device may generate an actual response curve of the ambient light sensor using the test data, and fit the actual response curve to a preset ideal response curve to obtain a compensation function, where the ideal response curve may be used to characterize a correspondence between different device poses and an output value of the ambient light sensor in an ideal state.

For example, since both the actual response curve and the ideal response curve may represent a relationship between the output values of the ambient light sensor corresponding to different device poses, for the same device pose, the electronic device may fit the output values on both the actual response curve and the ideal response curve in that device pose, thereby obtaining the compensation function.

With reference to the first aspect and the foregoing implementation manner, in some possible implementation manners, the compensation function includes any one of the following function types: a linear function, a nonlinear function; the nonlinear function may include, among other things, a polynomial function, a logarithmic function, an exponential function, a power function, and the like.

With reference to the first aspect and the foregoing implementation manner, in some possible implementation manners, the first ambient light data used for compensation by the electronic device may be ambient light original data output by an ambient light sensor, or may be data obtained by converting the ambient light original data.

For example, the ambient light raw data output by the ambient light sensor may be values of respective color components in the RGB color mode, and the data of actual ambient light intensity, color temperature, and the like of the current environment may be obtained by performing conversion processing on the respective color components in the RGB color mode. Therefore, the electronic device may compensate the first ambient light data by compensating the values of the respective color components in the RGB color mode, or may compensate the data such as the actual ambient light intensity and the color temperature of the current environment obtained after the conversion.

With reference to the first aspect and the foregoing implementation manner, in some possible implementation manners, the adjusting, by the electronic device, the display screen according to the second ambient light data may specifically include: and the electronic equipment determines display parameters of the display screen corresponding to the compensated second ambient light data, and adjusts the display screen according to the display parameters.

With reference to the first aspect and the foregoing implementation manner, in some possible implementation manners, after the electronic device determines the current device posture, compensation may be directly performed on original display parameters of the display screen instead of compensating for the first ambient light data output by the ambient light sensor. Specifically, the electronic device may determine an original display parameter of the display screen according to the first ambient light data, and then compensate the original display parameter according to the device gesture to obtain a compensated display parameter; and the display screen is adjusted by adopting the compensated display parameters.

The service scenario described in the embodiment of the present application is for more clearly describing the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application, and as a person of ordinary skill in the art can know that, with the appearance of a new service scenario, the technical solution provided by the embodiment of the present application is applicable to similar technical problems.

In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of the association object, indicating that three relationships may exist. For example, a and/or B may represent: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Currently, common ambient light detection methods include slit ambient light detection, under-screen ambient light detection, ejection/side-out ambient light detection, and the like. The angle of view of ambient light sensors is typically small when detecting ambient light due to limitations of the ambient light sensor and the light entry path. Before introducing the technical solution of the embodiment of the present application, a description is first given of the above-mentioned several commonly used methods for detecting ambient light.

Fig. 1 is a schematic diagram of a slit ambient light detection method according to an embodiment of the present application. In fig. 1, the ambient light sensor is placed below the display screen. Specifically, the glass cover plate of the display screen is arranged above the ambient light sensor, the circuit board and the battery cover inside the electronic equipment are arranged below the ambient light sensor, and the photosensitive area is a gap between the display screen and the middle frame of the electronic equipment. Since the display module of the display screen generally has no display function in the edge area, the glass cover plate can be blacked by ink in the area to form a black edge of the display screen. When the gap ambient light detection method is applied, the light-transmitting area in the black edge of the display screen can use the printing ink with the light semitransparent function, so that light can penetrate through the printing ink layer from the outside, and is downwards transmitted from the gap between the display module and the middle frame and irradiates on the ambient light sensor, thereby realizing the ambient light detection function. By using the slit ambient light detection method, the intensity of light transmitted through the slit needs to reach a certain value to be sensed by an ambient light sensor. Therefore, the width of the slit needs to satisfy a certain minimum value. The method cannot be used in the case that the gap between the display module and the middle frame of the electronic device is small or is blocked by the light-tight material. In addition, the gaps may cause the black edge of the display screen of the electronic device to be enlarged, which has negative effects on the screen ratio of the display area of the display screen of the electronic device and the aesthetic property of the electronic device.

Fig. 2 is a schematic diagram of an under-screen ambient light detection method according to an embodiment of the present application. By applying the under-screen ambient light detection method, an ambient light sensor can also be placed below the display screen of the electronic device, and the ambient light transmitted from the display screen area is detected by the ambient light sensor by utilizing the light transmittance of the display screen, so that the function of ambient light detection is realized. The under-screen ambient light detection method can save the internal space of the electronic equipment, and does not occupy the gap between the edge of the display screen and the middle frame. However, the under-screen ambient light detection method can only be applied to electronic equipment with a light-permeable display screen, and cannot be used for other types of light-impermeable display screens. In addition, due to the influence of the light transmission performance of the display screen, the light interference of the display screen, and the like, the noise of the light signal received by the ambient light sensor may be larger, which easily results in poor accuracy of the detection result.

Fig. 3 is a schematic diagram of an ejection/side-out ambient light detection method according to an embodiment of the present application. The liftout/side-out ambient light detection method is a technique that uses functional holes on the top or side of an electronic device to realize ambient light detection. For example, fig. 3 is an example of implementing ambient light detection by using an external sound outlet hole formed in a middle frame of the electronic device, where one or more sound outlet holes may be communicated with an ambient light sensor through the sound outlet hole of the electronic device, so as to conduct light in an external environment to the internal ambient light sensor, thereby implementing ambient light detection. Generally, the diameters of the sound outlet holes of the electronic device are smaller, and the middle frame needs to meet certain thickness requirements, so that the sound outlet holes are generally slender, and the transmission of light in the sound outlet holes is easy to generate loss. Therefore, in some cases, a light guide column with a light homogenizing function can be designed between the sound outlet hole of the electronic equipment and the ambient light sensor, so that light can be uniformly transmitted in the light guide column, scattering loss of light entering the hole is reduced, and detection sensitivity of the ambient light sensor is enhanced. In parallel, as shown in fig. 4, another schematic diagram of an ejection/side-out ambient light detection method according to an embodiment of the present application is shown, and fig. 4 is an example of implementing ambient light detection by sharing a sound outlet of a dust screen of an electronic device. The dustproof net can be located between the middle frame of the electronic equipment and the glass cover plate, small holes are formed in the dustproof net, light can penetrate through the small holes and can irradiate on the ambient light sensor through air or a light guide column, and detection of ambient light is achieved. Whether the common sound outlet hole or the dust screen sound outlet hole is shared, the aperture is usually smaller, and the manufacturing and assembling difficulties are larger when an ejection/side-outlet ambient light detection method is applied to the electronic equipment.

Whether slit ambient light detection, under-screen ambient light detection, or push-out/side-out ambient light detection is applied, ambient light sensors are often difficult to place in the optimal position on the front of an electronic device due to the shape of the electronic device and the layout of the ambient light sensors, which greatly affects the angular performance of the ambient light sensors. When there is a problem with the angular of view performance of ambient light sensors, electronic devices often cannot accurately measure the intensity of ambient light. Meanwhile, in the using process of the electronic equipment, the intensity of the ambient light measured by the ambient light sensor is also likely to be suddenly changed, so that abnormal dimming of the display screen is easily caused, and the using experience of a user is affected.

To improve the angular of view performance of the ambient light sensors, in some examples, two or more ambient light sensors may be arranged on the electronic device and the data of one of the ambient light sensors may be selected for reporting in combination with the readings of the acceleration sensor for the problem of limited angular of view performance of the single ambient light sensor. For example, a maximum value of data in two or more ambient light sensors is selected for reporting. However, installing multiple ambient light sensors in an electronic device clearly adds significant cost to the product as well as complexity to the architecture. Due to miniaturization of electronic devices and design with full screen, etc., the architecture space of electronic devices is becoming more and more intense, and it is also difficult to allow multiple ambient light sensors to be arranged in an electronic device. Also, even if a plurality of ambient light sensors are arranged in the electronic device, when some of the ambient light sensors are arranged in a poor position, the intensity data of the ambient light detected by them may not be accurate.

In view of the above problems, the embodiments of the present application provide a display screen adjustment method, by combining detection data of an attitude sensor in an electronic device, to compensate output data of an ambient light sensor, so that a response curve formed by the compensated output data approximates to a response curve formed by output data of the ambient light sensor with a relatively strong viewing angle performance, thereby achieving the purpose of enhancing the viewing angle performance of the ambient light sensor, improving accuracy of ambient light intensity data reported to a system, ensuring that the reported ambient light intensity data is closer to actual ambient light intensity of a current environment, and improving accuracy of adjusting backlight brightness, color temperature, and the like of a display screen by the electronic device based on the reported ambient light intensity data.

In the embodiment of the present application, the electronic device may be a mobile phone, a tablet computer, an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a notebook computer, a personal computer (personal computer, PC), a netbook, a personal digital assistant (personal digital assistant, PDA) or the like, which has a screen display function and is capable of adjusting backlight brightness and color temperature of a display screen based on ambient light intensity data detected by an ambient light sensor. The embodiment of the application does not limit the specific type of the electronic equipment.

As shown in fig. 6, the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, a sensor service, and the like.

For example, the application layer receives a registration request for calling various sensor data by each application program, reads the data output by the sensor, and the like.

Run time includes a core library and virtual machines. />runtime is responsible for->Scheduling and management of the system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part isIs a core library of (a). In an embodiment of the present application, the function may include a function for reading the ambient light data buffered in the lower buffer, such as the ambient light data reading function in fig. 6.

The converted data such as brightness, color temperature and the like of the ambient light are cached in an ambient light data cache, and the upper layer functions are read and called.

Based on the software architecture shown in fig. 6, referring to fig. 7, a schematic diagram of a reporting flow of ambient light sensor output data according to an embodiment of the present application is shown. According to the reporting flow shown in fig. 7, the sensor driver of the kernel layer may receive the raw data output by the ambient light sensor, process the raw data in the sensor driver, and output the converted ambient light data. These ambient light data may be buffered to an ambient light data buffer in the kernel layer. The sensor service of the application framework layer may regularly call an ambient light data reading function in the system layer, through which ambient light data is read from the ambient light data buffer, for use by the respective application of the application layer. The compensation of the output data of the ambient light sensor in the embodiment of the application is to compensate the original data output by the ambient light sensor or the ambient light data obtained after the conversion of the sensor drive in the sensor drive of the kernel layer.

Fig. 8 is a schematic diagram showing an effect of compensating output data of an ambient light sensor according to an embodiment of the present application. The abscissa in fig. 8 is the pitch angle (pitch) of the electronic device, and the ordinate is the output value of the ambient light sensor. The unit of the abscissa is the degree, and the angle of the electronic equipment rotating around the X axis of the coordinate system of the electronic equipment can be represented; the output value of the ambient light sensor represented by the ordinate may be ambient light intensity data, and the unit size thereof may be determined according to different ambient light sensors, which is not limited by the embodiment of the present application.

Referring to fig. 9, a schematic diagram of an electronic device coordinate system according to an embodiment of the present application is shown. In the electronic device coordinate system shown in fig. 9, the origin may be a center point of the electronic device display screen, a plane formed by an X axis and a Y axis of the electronic device coordinate system is parallel to the electronic device display screen, and a Z axis is perpendicular to the electronic device display screen. Wherein the X-axis may be used to represent a left-right direction on a plane formed by a display screen of the electronic device and the Y-axis may be used to represent an up-down direction on a plane formed by a display screen of the electronic device. When a user is using the electronic device, the display screen of the electronic device rotates around the X axis to form a pitch angle, rotates around the Y axis to form a roll angle (roll), and rotates around the Z axis to form a yaw angle (yaw).

In fig. 8, a curve L1 is a response data curve formed based on current ambient light intensity data detected by an ambient light sensor in the electronic device, and the response data curve L1 is an uncompensated original response curve. The maximum output value of the ambient light sensor in the response data curve L1 is about 24000, and the pitch angle of the corresponding electronic device is about 45 degrees. It should be noted that, due to the type of the ambient light sensor and the type of the output data thereof, there is a large difference in the magnitudes of the output values of different ambient light sensors, and the units of these output values may also be different. The unit of the output value of the ambient light sensor in fig. 8 is not limited in the embodiment of the present application. As can be seen from fig. 8, the maximum output value 24000 is about the output value 12000 when the maximum output value 24000 is attenuated to half, and the pitch angle of the electronic device corresponding to the output value 12000 is about 18 degrees. It can be seen that, before uncompensated, when the pitch angle of the electronic device is within the range of 18-45 degrees, the ambient light sensor can accurately detect the ambient light intensity of the current environment, that is, the field angle performance of the ambient light sensor is relatively good when the pitch angle of the electronic device is within the range of 18-45 degrees.

The curve L2 in fig. 8 is an ideal response curve, and the ideal response curve L2 can be regarded as a response curve formed by detecting the ambient light intensity of the current environment when the ambient light sensor is mounted at a certain position of the electronic device and the layout structure is not limited and the ambient light sensor has good performance. The ideal response curve L2 described above may be formed, for example, when an ambient light sensor is arranged on the front of the display screen of the electronic device and its performance is not affected by other components or structures of the electronic device, with which ambient light intensity of the current environment is detected. As can be seen from fig. 8, the maximum output value of the ambient light sensor in the ideal response curve L2 is about 17000, and the pitch angle of the corresponding electronic device is about 45 degrees. As is clear from fig. 8, the maximum output value 17000 is about the output value 8500 when the maximum output value 17000 is attenuated to half, and the pitch angle of the electronic device corresponding to the output value 8500 is about 5 degrees. It can be seen that, under ideal conditions, when the pitch angle of the electronic device is within the range of 5-45 degrees, the ambient light sensor can accurately detect the ambient light intensity of the current environment, that is, the view angle performance of the ambient light sensor is relatively better when the pitch angle of the electronic device is within the range of 5-45 degrees, and the pitch angle range is obviously larger than the pitch angle range corresponding to the uncompensated original response curve.

As shown in fig. 8, the curve L3 is a response curve after compensation. The embodiment of the present application compensates the output data of the ambient light sensor, that is, compensates the response data curve L1 in fig. 8, so that the compensated response curve L3 approximates to the ideal response curve L2. In some implementations, the compensation for the original response data curve L1 may be performed in a linear, nonlinear compensation manner; in other implementations, the original response data curve L1 may be compensated by using a hyperbolic or quadratic curve compensation method, so as to obtain a compensated response curve L3. As can be seen from fig. 8, the maximum output value of the ambient light sensor in the compensated response curve L3 is about 17000, and the pitch angle of the corresponding electronic device is about 45 degrees. The maximum output value 17000 is about 8500 when it is attenuated to half according to the definition of the view angle of the ambient light sensor. In fig. 8, the pitch angle of the electronic device corresponding to the output value 8500 is about 5 degrees. After the original response data curve L1 is compensated, when the pitch angle of the electronic device is within a range of 5-45 degrees, the ambient light sensor can also accurately detect the ambient light intensity of the current environment, that is, by compensating the output data of the ambient light sensor, the view angle performance of the ambient light sensor can be close to the view angle performance under ideal conditions, so that when the pitch angle of the electronic device is within a larger angle range, the ambient light sensor can also obtain relatively good view angle performance.

The following describes the technical scheme of the present application with reference to specific embodiments.

Example 1

Fig. 10 is a schematic diagram of a method for adjusting a display screen according to an embodiment of the present application, where the method specifically includes the following steps:

s1001, the electronic equipment reads the gesture data of the gesture sensor.

In an embodiment of the present application, the attitude sensor may include an acceleration sensor, a magnetometer, a gyroscope, and the like. The electronic device can read attitude data output by any one or more of the acceleration sensor, the magnetometer and the gyroscope.

The electronic device may read data output by the acceleration sensor as posture data for calculating the inclination angle later, or may read data output by the magnetometer as posture data; or the electronic equipment can also read the data output by the acceleration sensor and the magnetometer at the same time, and the data output by the two sensors are used as posture data for calculating the inclination angle later.

It should be noted that, the electronic device may read the gesture data of the gesture sensor under the control of the processor of the electronic device.

S1002, the electronic equipment calculates the current pitch angle according to the attitude data.

The gesture data output by the gesture sensor may be used to determine a specific gesture of the electronic device in a current state. Generally, the posture of an electronic device may be determined according to the inclination angle of a user when using the electronic device. At different tilt angles, the display screen orientation of the electronic device is also different.

As can be seen from fig. 9, when the user uses the electronic device, the inclination angle of the electronic device may include an angle formed by rotating the display screen around the X-axis of the coordinate system of the electronic device, i.e., pitch angle (pitch), an angle formed by rotating the display screen around the Y-axis, i.e., roll angle (roll), and an angle formed by rotating the display screen around the Z-axis, i.e., yaw angle (yaw).

Typically, since the ambient light sensor is mainly laid out on the top half and the top of the electronic device. For example, the ambient light sensor in a cell phone is typically placed under the top half of the display on the front of the cell phone or on top of the cell phone. In this way, the impact of how the user holds the electronic device when using the electronic device is greatest on the ambient light sensor. Also, the most common change in attitude of an electronic device is a change in pitch angle for the user. Therefore, after the electronic equipment reads the gesture data of the gesture sensor, the current pitch angle of the electronic equipment can be calculated according to the gesture data, and the influence of the angle change of the roll angle and the yaw angle on the ambient light sensor is ignored.

S1003, the electronic device receives the first ambient light data output by the ambient light sensor.

The ambient light sensor can be used for sensing the intensity of light of the current environment of the electronic equipment and outputting corresponding data. The first ambient light data may be data that the ambient light sensor outputs for a current ambient light intensity variation. When the electronic equipment determines that the self inclination angle changes according to the posture data output by the posture sensor, the electronic equipment needs to confirm whether the ambient light also changes under different inclination angles, so that the backlight brightness, the color temperature and the like displayed on the display screen are conveniently adjusted according to different ambient light intensities, and the display screen is adapted to the current ambient light. Thus, the electronic device may receive the first ambient light data output by the ambient light sensor in real time.

S1004, the electronic equipment determines second ambient light data according to the pitch angle and the first ambient light data.

In the embodiment of the present application, the second ambient light data may be ambient light data obtained after the electronic device compensates the first ambient light data according to the device gesture.

In some scenarios, the data about the ambient light detected by the ambient light sensor may not be accurate, subject to differences in the layout, architecture of the ambient light sensor. For example, when the tilt angle of the electronic device changes, the ambient light of the current environment in which the electronic device is located may not change, but the output data may show that the ambient light changes greatly due to the performance of the ambient light sensor. Therefore, in order to compensate for adverse effects on ambient light detection due to layout and architecture defects of the ambient light sensor, the embodiment of the application can compensate for the first ambient light data output by the ambient light sensor. By compensation, the performance of the ambient light sensor is indirectly improved.

Because the angle change of the pitch angle of the electronic device has the greatest influence on the ambient light sensor, in the embodiment of the application, the electronic device can compensate the first ambient light data output by the ambient light sensor according to the calculated pitch angle.

In one implementation, the electronic device may compensate for the original data of the first ambient light data. In another implementation, since the ambient light raw data output by the ambient light sensor needs to be converted to be used by the electronic device for subsequent display adjustment, the electronic device may also compensate the first ambient light data.

For example, for the first ambient light data output by the ambient light sensor, the raw data thereof may be values of respective color components in Red Green Blue (RGB) color mode. The electronic device needs to convert the RGB values to obtain values of ambient light intensity, color temperature, and the like. The ambient light data reported by the electronic device to the processor for display screen adjustment should be converted ambient light intensity, color temperature, etc. Thus, in one implementation, the electronic device may compensate the first ambient light data by compensating the RGB values, and converting the RGB values to values of ambient light intensity, color temperature, etc. after the compensation. In another implementation, the electronic device may also compensate for the first ambient light data by compensating for values of the converted ambient light intensity, color temperature, etc.

In the embodiment of the application, the electronic device can compensate the first ambient light data through a corresponding compensation function. The compensation function may be a linear or nonlinear compensation function, or may be a quadratic curve, a hyperbolic curve or other compensation function, and the specific type or form of the compensation function is not limited in the embodiments of the present application.

In one example, the compensation function may be expressed as a linear functional form of y=ax+b, where x is an independent variable, y is a dependent variable, and a and b are parameters. In another example, the compensation function may also be expressed in the form of a polynomial-like function of y=ax≡2+bx+c, where x is an argument, y is a dependent variable, and a, b and c are parameters.

After the electronic device calculates the pitch angle according to the attitude data, the electronic device can calculate a corresponding y value by taking the calculated pitch angle as the value of x in the compensation function, and take the y value as the compensated second ambient light data.

For example, if the electronic device compensates the ambient light by compensating the converted ambient light intensity, the electronic device may calculate the compensated ambient light intensity using a compensation function according to the calculated pitch angle.

In one possible implementation, the compensation function may be derived by processing the actual response curve of the ambient light sensor output data as well as the ideal response curve. As can be seen from fig. 8, the curve L1 is an actual response data curve formed based on the current ambient light intensity data detected by the ambient light sensor in the electronic device, the curve L2 is an ideal response curve, and the corresponding compensation function can be obtained by performing data fitting on the curves L1 and L2. Thus, after the electronic device calculates the current pitch angle, the ambient light data calculated according to the pitch angle and the compensation function is approximately equal to the ambient light data corresponding to the pitch angle in the ideal response curve.

In practical applications, the actual response curve and the ideal response curve of the output data of the environmental light sensor in the electronic device may be obtained through experiments. For example, for a certain type of electronic device, the actual response curve may be obtained by placing the electronic device in a set environment and testing the ambient light data output by its ambient light sensor at different inclination angles. For the ideal response curve, the ideal response curve can be obtained by testing the ambient light sensor of the electronic equipment under the conditions of better position, layout and architecture by adopting the same testing method. The compensation function obtained based on the actual response curve and the ideal response curve can be built in the electronic equipment for subsequent compensation.

In the embodiment of the application, the electronic equipment can compensate the output data of the ambient light sensor based on the pitch angle by reading the attitude data of the attitude sensor and calculating to obtain the current pitch angle. Because the pitch angle is the most obvious factor influencing the ambient light sensor in the use process of the electronic equipment, the electronic equipment compensates the ambient light output data based on the pitch angle, the compensation effect can be ensured, the data quantity required to be processed in the compensation process is reduced to the greatest extent, and the compensation efficiency is improved.

For the compensated second ambient light data, the electronic device may be configured to adjust a backlight brightness, a color temperature, etc. of the display screen, so that the adjusted display screen is more suitable for viewing by human eyes.

Example two

Fig. 11 is a schematic diagram of another display screen adjustment method according to an embodiment of the present application, where the method specifically includes the following steps:

s1101, the electronic device reads the gesture data of the gesture sensor.

S1102, the electronic equipment calculates the current attitude angle according to the attitude data.

The first embodiment is an introduction of compensating the output data of the ambient light sensor based on the change of the pitch angle of the electronic device; in the second embodiment, a process of compensating the output data of the ambient light sensor based on a change of an attitude Angle (Euler Angle) of the electronic device is described.

As can be seen from fig. 9, when the user uses the electronic device, the inclination angle of the electronic device is not changed only by the angle of the pitch angle formed by rotating the electronic device around the X-axis of the electronic device coordinate system. Tilting of the electronic device may also cause a change in the angle of the roll angle formed by rotation about the Y axis and the yaw angle formed by rotation about the Z axis. The angular changes of the electronic device rotating around the X axis, the Y axis and the Z axis of the self coordinate system can be represented by using attitude angles, and the attitude angles represent the overall inclination condition of the electronic device in three dimensions.

Similar to the embodiment, in the case that a plurality of different similar gesture sensors are installed in the electronic device, the electronic device can select and read gesture data output by any one or any of the plurality of sensors. For example, the electronic device may read only the data output by the acceleration sensor as the posture data of the subsequent calculated tilt angle, or may read the data output by the acceleration sensor and the magnetometer at the same time, and use the data output by both the acceleration sensor and the magnetometer as the posture data of the subsequent calculated tilt angle. The electronic device may then calculate a current attitude angle from the attitude data.

In one implementation, the electronic device may calculate, according to the read gesture data, angles of rotation of the electronic device about the X-axis, the Y-axis, and the Z-axis of its own coordinate system in the current state, respectively. That is, the electronic device may first calculate the pitch angle, the roll angle, and the yaw angle from the attitude data. Then, the electronic equipment performs fusion processing on the pitch angle, the roll angle and the yaw angle to obtain the attitude angle of the electronic equipment.

S1103, the electronic device receives the first ambient light data output by the ambient light sensor.

And S1104, the electronic equipment compensates the first ambient light data according to the attitude angle to obtain compensated second ambient light data.

In the embodiment of the application, the electronic device compensates the first ambient light data according to the attitude angle, which may be the compensation of the original data output by the ambient light sensor, or may be the compensation of the ambient light intensity, the color temperature and other data after the ambient light sensor drives to convert the original data to obtain the ambient light intensity, the color temperature and other data.

In one possible implementation, the electronic device may use the calculated attitude angle as an input of the compensation function according to a built-in compensation function, and use an output value of the compensation function as the compensated second ambient light data. For example, if the electronic device compensates the ambient light intensity, the posture angle may be used as a value of a central argument of a compensation function corresponding to the ambient light intensity, and the compensated ambient light intensity may be calculated using the compensation function.

The compensation function in the second embodiment can also be obtained by processing the actual response curve and the ideal response curve of the ambient light sensor output data in a similar manner to the manner in which the compensation function in the first embodiment is determined. The difference is that when determining the actual response curve and the ideal response curve under the three-dimensional condition, the angle change condition of the attitude angle of the electronic equipment in the test process, namely the rotation condition of the electronic equipment around the coordinate axis of the electronic equipment in three directions, should be considered.

Fig. 12 is a schematic diagram showing an output data compensation effect of another ambient light sensor according to an embodiment of the present application. Fig. 12 shows the effect of compensating the output data of the ambient light sensor based on the angular change of the attitude angle. The black triangle in fig. 12 is the origin of the coordinate system, and the vector direction formed by the connection line between the origin of the coordinate system and any other data point in the figure represents the normal vector of the screen of the electronic device in the gesture, and the normal vector of the screen can be used for representing the gesture angle of the electronic device. Curve l in FIG. 12 ₁ Is the curve before compensation, that is, the actual response curve of the data output by the ambient light sensor; curve l ₂ The curve is obtained by adopting a nonlinear compensation function to compensate the data output by the ambient light sensor. As can be seen from FIG. 12, curve l ₂ More planar, the view angle performance of the corresponding ambient light sensor is better.

Because the electronic device rotates in the pitch direction and rotates in other directions during use, compared with the first embodiment which only considers rotation in the pitch direction, the second embodiment simultaneously considers rotation in the pitch direction, the roll direction and the yaw direction. In the second embodiment, the attitude of the electronic device in the three-dimensional space is calculated by using the attitude sensor, so that the output of the ambient light sensor is compensated based on the attitude angle in the three-dimensional space, and the rotation of the electronic device in different directions can be fully considered, thereby being beneficial to obtaining a better compensation effect.

And S1105, the electronic equipment adjusts the display screen according to the second ambient light data.

The electronic equipment can adjust parameters such as backlight brightness and color temperature of the display screen according to the compensated second ambient light data, so that the adjusted backlight brightness and color temperature are matched with actual light intensity of the current environment, and the human eye comfort level of a user when the user uses the electronic equipment is improved.

With reference to the foregoing description of the first embodiment and the second embodiment, when any one of the device posture of the electronic device and the first ambient light data output by the ambient light sensor is changed, the electronic device may implement adjustment of the display screen according to the technical solution provided by the embodiment of the present application.

In some embodiments, when the ambient light of the environment in which the electronic device is currently located changes, the first ambient light data output by the ambient light sensor will also change. In this case, the electronic device may compensate the changed first ambient light data according to the current device posture, so as to implement adjustment of backlight brightness and color temperature of the display screen. For example, when the electronic device is in a certain fixed device posture, the device posture of the electronic device calculated based on the posture data output by the posture sensor is a fixed value, that is, the device posture of the electronic device is not changed. Meanwhile, the electronic equipment can also adjust the display screen because the first ambient light data output by the ambient light sensor changes.

In other embodiments, if the first ambient light data output by the ambient light sensor is unchanged, but the device posture of the electronic device is changed, the electronic device may also compensate the first ambient light data according to the changed device posture, so as to implement adjustment of the display screen. Illustratively, in some scenarios, the first ambient light data detected and output by the ambient light sensor is constant, but the position, orientation, etc. where the electronic device is located changes, which may result in a change in the gesture data output by the gesture sensor. Correspondingly, the device gesture obtained by the electronic device according to the gesture data will also be different, i.e. the device gesture of the electronic device changes. In this case, the electronic device may compensate the first ambient light data that is unchanged based on the changed device posture, thereby adjusting the display screen according to the compensation result.

Example III

Fig. 13 is a schematic diagram of another display screen adjustment method according to an embodiment of the present application, where the method specifically includes the following steps:

s1301, the electronic equipment reads the gesture data of the gesture sensor.

S1302, the electronic equipment calculates the current inclination angle according to the gesture data.

In the embodiment of the application, the current inclination angle calculated by the electronic equipment according to the gesture data can be the pitch angle of the electronic equipment or the gesture angle. The process of the electronic device reading the attitude data of the attitude sensor and calculating the pitch angle or the attitude angle according to the attitude data can be referred to the description in the first embodiment and the second embodiment, and the description of the embodiment of the present application is omitted.

And S1303, the electronic equipment compensates the display parameters according to the inclination angle.

In the first and second embodiments, the purpose of the electronic device to compensate the ambient light data may be to adjust the display parameters of the display screen according to the compensated ambient light data. In general, display parameters of a display screen have a certain correspondence with different ambient light data. Illustratively, taking the backlight brightness of a display screen as an example, for a certain electronic device, a functional expression of ambient light data and the backlight brightness of the display screen to be adjusted may be stored therein. Based on the ambient light data detected by the ambient light sensor and having different sizes, the electronic device can adjust the backlight brightness of the display screen according to the functional expression. In general, the functional expression of the ambient light data and the backlight brightness of the display screen to be adjusted can be expressed in a piecewise linear function mode, and the functional expression is different for different electronic devices and display screens made of different materials.

Therefore, in the embodiment of the application, after the electronic device calculates the current inclination angle and other data according to the gesture data, the original display parameters of the display screen can be directly compensated by utilizing the corresponding compensation function based on the inclination angle. Wherein the original display parameters of the display screen may be determined from the first ambient light data output by the ambient light sensor.

In one possible implementation manner, taking the electronic device to compensate the display parameters of the display screen according to the pitch angle as an example, the electronic device may fuse the compensation function in the first embodiment with the functional expression of the ambient light data and the backlight brightness of the display screen to be adjusted, to obtain a fusion compensation function directly used for compensating the display parameters of the display screen according to the pitch angle. After the electronic equipment calculates the current pitch angle according to the attitude data, the pitch angle can be used as input data, and the fusion compensation function is utilized to output the value of the backlight brightness of the display screen to be adjusted. The electronic device may then adjust the display screen based on the value of the output backlight brightness.

In another possible implementation manner, taking the electronic device to compensate the display parameters of the display screen according to the attitude angle as an example, the electronic device may fuse the compensation function in the second embodiment with the functional expression of the ambient light data and the backlight brightness of the display screen to be adjusted, to obtain a fused compensation function directly used for compensating the display parameters of the display screen according to the attitude angle. After the electronic device calculates the current attitude angle according to the attitude data, the electronic device can output the value of the backlight brightness of the display screen to be adjusted by using the fusion compensation function by taking the attitude angle as input data. The electronic device may then adjust the display screen based on the value of the output backlight brightness.

In the embodiment of the application, the electronic device can directly compensate the display parameters of the display screen according to the calculated current inclination angle, and compared with the first embodiment and the second embodiment, which compensate the ambient light data output by the ambient light sensor according to the inclination angle and then adjust the display parameters of the display screen according to the compensated ambient light data, the embodiment omits the intermediate step of adjusting the ambient light data, reduces the probability of erroneously adjusting the display parameters, and improves the accuracy of adjusting the display parameters.
