[0037] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0038] The brightness adjustment method provided in the present disclosure is applied to the screen brightness adjustment scenario of a terminal, for example, to the screen brightness adjustment scenario of a wearable device.

[0039] With the development of terminal technology, the display screen of the terminal device can be partially lit in the screen-off state. In the present disclosure, the terminal can be a mobile phone, a tablet, a smart watch, etc. This partially lit screen display mode is called AOD mode. In AOD mode, the display screen is only partially lit. Compared with the entire screen being lit, the number of lit pixels is small, which can save power consumption. At the same time, in AOD mode, since the display screen is partially lit, some information can be displayed in the partially lit pixels. Taking wearable devices as an example, Figure 1 is a schematic diagram of a wearable device when the screen is on according to an exemplary embodiment. Figure 1 As shown, the installed applications can be displayed normally, or when the application is running, the display brightness is normal brightness instead of the screen-off display brightness. Figure 2 This is a schematic diagram of a wearable device in the AOD mode when the screen is off, according to an exemplary embodiment. Only some pixels on the screen are lit to display information such as time. This mode can save power. In related technologies, in order to ensure that the screen display brightness in the AOD mode can change according to the ambient light, a light sensor is used to collect ambient brightness information in real time and adjust the screen display brightness. However, this solution increases power consumption and makes it difficult to ensure the user experience.

[0040] In order to solve the above problems, the present disclosure proposes a brightness adjustment method. After the terminal enters the screen-off display mode, the light sensor is turned off, and the corresponding screen-off display brightness is determined by the brightness of the most recently lit screen display to adjust the screen-off display brightness of the display screen.

[0041] Figure 3 is a flow chart of a brightness adjustment method according to an exemplary embodiment, the method is applied to a terminal, such as Figure 3 As shown, the method includes steps S11, S12 and S13.

[0042] In step S11, in response to the display screen of the terminal entering the AOD mode, the light sensor of the terminal is turned off, and the first bright screen display brightness is obtained.

[0043] In the disclosed embodiment, when the terminal enters the AOD mode, the light sensor of the terminal is turned off to reduce power consumption.

[0044] The first screen display brightness is the screen display brightness before the display screen enters the AOD mode, and is also used as a data source for further determining the screen display brightness in the AOD mode.

[0045] In step S12, according to the correspondence between the on-screen display brightness and the off-screen display brightness, the first off-screen display brightness corresponding to the first on-screen display brightness is determined.

[0046] The on-screen display brightness is the brightness of the terminal when the display screen is fully lit, and the off-screen display brightness is the brightness when the display screen is only partially lit after the terminal enters the AOD mode. Due to the optical characteristics of the display screen, there is a corresponding relationship between the off-screen display brightness and the on-screen display brightness. After entering the AOD mode, different on-screen display brightnesses of the display screen will form an off-screen display brightness corresponding to the on-screen display brightness. Based on the corresponding relationship between the on-screen display brightness and the off-screen display brightness of the terminal display screen, the first off-screen display brightness is determined using the first on-screen display brightness. The first off-screen display brightness is the corresponding off-screen display brightness after the display screen enters the off-screen mode from the first on-screen display brightness.

[0047] In the embodiment of the present disclosure, based on the relationship between the on-screen display brightness and the off-screen display brightness, the off-screen display brightness is determined using the on-screen display brightness, thereby providing an accurate brightness determination method for obtaining the off-screen display brightness of the display screen.

[0048] In step S13, the off-screen display brightness of the display screen is adjusted to a first off-screen display brightness.

[0049] The first off-screen display brightness is the display brightness of the screen after the display screen enters the off-screen display state from the bright screen display state. The display brightness of the off-screen state of the display screen of the terminal is set to the off-screen display brightness determined according to the bright screen display brightness.

[0050] In the embodiment of the present disclosure, the off-screen display brightness of the display screen is adjusted to the first off-screen display brightness, and the brightness adjustment in the off-screen display state is completed. Through the present disclosure, the problem of high light sensing power consumption and narrow brightness adjustable range in the off-screen display mode is solved.

[0051] In the disclosed embodiment, the brightness of the screen display is adjusted by the brightness of the screen before the screen is turned off, so as to avoid the problem of high power consumption caused by the continuous operation of the light sensor when the screen is turned off. When users use the terminal for a long time, they need both long battery life brought by low power consumption and a comfortable experience that the display can adapt to the ambient brightness. Therefore, when the terminal is in the screen-off display state, the screen-off display brightness can also be adaptively adjusted according to the ambient light brightness. That is, in order to ensure that the screen-off display brightness can match the changes in ambient light, the screen-off display brightness needs to be calibrated.

[0052] Figure 4 is a flow chart of a brightness adjustment method according to an exemplary embodiment. Figure 4 As shown, it includes step S21 and step S22.

[0053] In step S21, when it is detected that the display screen meets the preset conditions in the AOD mode, the light sensor is started to collect the current ambient light brightness data.

[0054] The preset condition is used to determine whether the display state of the display screen in the AOD mode needs to be switched.

[0055] In the disclosed embodiment, it is detected that the display screen meets the preset conditions in the AOD mode, and there are the following situations: the target posture of the terminal is detected, and / or the target operation of the terminal user is detected. Among them, the target posture is a specific posture that triggers the terminal's own posture to change so that the display state of the display screen is switched, such as a wrist-raising gesture. The target operation is an operation in which the user performs a specific operation on the terminal to switch the display state of the display screen, such as double-clicking the screen, pressing the power button, and the user's face approaching the screen. The detection of the target posture can be detected by the acceleration sensor in the terminal, specifically including: the acceleration sensor collects acceleration data, and analyzes and detects the target posture from the acceleration data.

[0056] In the disclosed embodiment, when the target gesture is detected, it is necessary to determine whether the switch for the current terminal to perform the corresponding operation in response to the target gesture is turned on. If the switch is turned on, the display screen will switch from the bright screen display state to the off screen display state; if the switch is turned off, the display screen will continue to maintain the off screen display state. Correspondingly, when the target operation of the terminal user is detected, it is also necessary to determine whether the switch for the current terminal to perform the corresponding operation in response to the target operation is turned on. If it is turned on, the display screen state is switched, and if it is turned off, the current off screen display state is maintained.

[0057] To ensure that the display brightness of the display in AOD mode can match the ambient brightness, the display brightness needs to be calibrated. The light sensor needs to be started to collect the ambient light brightness.

[0058] In step S22, the first off-screen display brightness is corrected according to the current ambient light brightness data.

[0059] After the current ambient light brightness data is acquired by the light sensor, the first off-screen display brightness can be corrected based on the current ambient light brightness data. The first off-screen display brightness is the display brightness of the display screen in the AOD mode determined according to the ambient light brightness acquired by the light sensor.

[0060] When calibrating the display brightness of the display screen, the terminal can calibrate the display brightness of the screen on according to the ambient light brightness, or calibrate the display brightness of the screen off according to the ambient light brightness. Figure 5 It is a schematic diagram of a curve showing the relationship between ambient light and the display brightness and the bright screen display brightness of a display screen in AOD mode according to an exemplary embodiment. At different ambient light brightnesses, the screen brightness when the screen is off is different. At different ambient light brightnesses, the screen brightness when the screen is on is also different. That is, under different ambient light, different first off-screen display brightnesses can correspond. For example, when the wearable device turns off the screen when the wrist is raised, the accelerometer-sensor (A+G) module detects the wrist raising action and starts the light sensing module to collect ambient light data. The data is directly transmitted to the system platform, and the AOD off-screen display brightness and ambient light brightness curve are called for correction.

[0061] In the disclosed embodiment, the display brightness of the display screen in the AOD mode is corrected by using the ambient light brightness data collected by the light sensor, thereby ensuring that the display brightness in the AOD mode can be updated and providing accuracy of the display screen brightness.

[0062] In the disclosed embodiment, the off-screen display brightness of the display screen is corrected by the ambient light brightness data collected by the light sensor, and the light sensor is activated when the display screen meets a preset condition. If the preset condition triggers the display screen to switch from the off-screen display state to the bright screen display state, the current display state of the display screen has been switched to the bright screen display state. For example, a target gesture / target operation is detected and the target gesture / target operation can trigger the display screen to switch from the off-screen display state to the bright screen display state. That is, when it is determined that the display screen switches from the off-screen display state to the bright screen display state, the off-screen display brightness is corrected by the following brightness adjustment method.

[0063] Figure 6 is a flow chart of a method for correcting the first off-screen display brightness according to current ambient light brightness data according to an exemplary embodiment. Figure 6 As shown, the following steps are included.

[0064] In step S31, the second bright screen display brightness is determined according to the current ambient light brightness data.

[0065] If a target gesture / target operation is detected, and the target gesture / target operation is set to the gesture for waking up the display screen, that is, it is necessary to switch from the off-screen display mode to the normal display mode. If the switch for performing the corresponding operation based on the target gesture / target operation is in the on state, then the AOD mode is exited and the normal display mode is entered, which is equivalent to adjusting the brightness of the bright screen display to match the current ambient light brightness in the bright screen display state.

[0066] After the current ambient light brightness data is collected by the light sensor, the second bright screen display brightness is determined, wherein the second bright screen display brightness is the bright screen display brightness corresponding to the currently collected ambient light brightness data.

[0067] In step S32, based on the correspondence between the on-screen display brightness and the off-screen display brightness, a second off-screen display brightness corresponding to the second on-screen display brightness is determined.

[0068] If the user does not perform any operation within the preset time, the display screen will re-enter the off-screen display mode and re-calibrate the off-screen display brightness. At this time, the off-screen display brightness is adjusted based on the determined second on-screen display brightness.

[0069] The second off-screen display brightness is the off-screen display brightness corresponding to the bright screen display brightness determined by the display screen according to the ambient light brightness after entering the off-screen display mode. The off-screen display brightness corresponding to the bright screen display brightness is determined according to the corresponding relationship curve between the bright screen display brightness and the off-screen display brightness of the terminal display screen. This relationship curve between the bright screen display brightness and the off-screen display brightness is measured in the laboratory.

[0070] In step S33, the second screen-off display brightness is determined as the first screen-off display brightness.

[0071] The first off-screen display brightness value is updated using the determined second off-screen display brightness value.

[0072] In one implementation of the present disclosure, Figure 7 The diagram is a schematic diagram of a corresponding relationship curve between the brightness of the screen on and the brightness of the screen off according to an exemplary embodiment. Different brightness of the screen on corresponds to different brightness of the screen off.

[0073] The second off-screen display brightness corresponding to the second on-screen display brightness is used to update the first off-screen display brightness, so that the off-screen display brightness of the terminal can be updated and corrected in a timely manner. For example, when the screen is on, the light sensor collects the current ambient light brightness data, and determines the corresponding on-screen display brightness based on the current ambient light brightness data. When the screen is off after a timeout, the current off-screen display brightness will be determined based on the most recent on-screen display brightness, and the off-screen display brightness can be updated in a timely manner.

[0074] In the disclosed embodiment, the brightness of the corresponding display screen is determined by the ambient light brightness, and then the corresponding off-screen display brightness value is determined by the brightness of the display screen, and the off-screen display brightness value is used to update the off-screen display brightness. For example, taking the target posture as the wrist-raising screen-raising as an example, when the wrist-raising screen-raising is turned on, the A+G acceleration sensor module data is transmitted to the system platform, the light sensing module is started to collect ambient light data, and the on-screen display brightness and ambient light brightness curve are used to calibrate the on-screen display brightness. When the AOD off-screen display mode is subsequently entered, the AOD off-screen display brightness is corrected according to the off-screen display brightness and the on-screen display brightness curve in the AOD off-screen display mode.

[0075] In related scenarios, in order for users to view the information displayed on the screen more clearly and comfortably when using the terminal, the terminal needs to adjust the brightness of the display according to user operations / user postures. In particular, when the user views the screen content of the terminal in detail, the brightness of the display needs to be intelligently adjusted to match the current ambient light brightness.

[0076] In the embodiment of the present disclosure, if the preset condition does not trigger the switching of the display state of the display screen, that is, the display state of the current display screen is still in the off-screen display state. For example, the target gesture / target operation is detected but the target gesture / target operation cannot trigger the display screen to switch from the off-screen display state to the bright-screen display state. That is, when it is determined that the display screen is in the off-screen display state, the off-screen display brightness is corrected by the following brightness adjustment method.

[0077] Figure 8 is a flow chart of a method for correcting the first off-screen display brightness according to current ambient light brightness data according to an exemplary embodiment. Figure 8 As shown, the following steps are included.

[0078] In step S41, according to the correspondence between the ambient light brightness data and the screen-off display brightness, a third screen-off display brightness corresponding to the current ambient light brightness data is determined.

[0079] If the target gesture / target operation is detected and the target gesture / target operation cannot wake up the display, the display will not switch from the off-screen display state to the on-screen display state, that is, the off-screen display state will continue. However, since the current ambient light data state may have changed, the off-screen display brightness of the off-screen display state needs to be readjusted. In this case, the off-screen display brightness needs to be adjusted to match the current ambient light brightness according to the correspondence between the ambient light brightness data and the off-screen display brightness in the off-screen display state so that the user can view it.

[0080] In step S42, the third screen-off display brightness is determined as the first screen-off display brightness.

[0081] In the off-screen display state, since it has not switched to the bright screen display state, but the light sensor is turned on, the brightness of the current display still needs to adapt to the current ambient light brightness. At this time, the off-screen display brightness is adjusted according to the ambient light brightness data. Specifically, the off-screen display brightness of the display is adjusted according to the ambient light brightness data. Figure 5 The corresponding relationship curve between the ambient light brightness and the screen off display brightness is determined. The screen off display brightness corresponding to the current ambient light brightness data is used as the third screen off display brightness.

[0082] The corresponding off-screen display brightness is obtained through the current ambient light brightness, and the off-screen display brightness is updated. That is, the third off-screen display brightness is used as the first off-screen display brightness.

[0083] In the disclosed embodiment, when the target posture is detected and the display screen is still in the screen-off display state, the screen-off display brightness is determined based on the corresponding relationship between the ambient light display brightness and the screen-off display brightness.

[0084] The above determination of the screen display brightness by ambient light, or determination of the screen off display brightness by the display brightness of the display screen on, requires a corresponding mapping model to provide a corresponding relationship of brightness data.

[0085] In one implementation of an embodiment of the present disclosure, the display state of the display screen can be an off-screen display state or a bright-screen display state, wherein the off-screen display state is the display state of the terminal in AOD mode, and the bright-screen display state is the display state of the terminal in normal mode.

[0086] In one implementation of the present disclosure, Figure 5 The relationship curve between the ambient light brightness data and the display screen brightness when the display is on and the corresponding relationship curve between the ambient light brightness data and the display screen brightness when the display is off. It reflects the mapping relationship between the ambient light brightness data and the display screen brightness when the display is on, and the mapping relationship between the ambient light brightness data and the display screen brightness when the display is off. That is, the current corresponding display screen brightness when the display is on and the display screen brightness when the display is off can be determined by the ambient light brightness data.

[0087] In one implementation of the present disclosure, Figure 7 The relationship curve between the on-screen display brightness and the off-screen display brightness of the display screen shown. Among them, the on-screen display brightness is the brightness when the terminal's display screen is fully lit, and the off-screen display brightness is the brightness when the display screen is only partially lit after the terminal enters the AOD mode. According to the optical characteristics of the display screen, there is a corresponding relationship between the on-screen display brightness of the same display screen before entering the AOD mode and the off-screen display brightness after entering the AOD mode, that is, different on-screen display brightness of the display screen will form an off-screen display brightness corresponding to the on-screen display brightness after entering the AOD mode.

[0088] In one implementation of the present disclosure, Figure 5 and Figure 7 The brightness relationship curves are all fitted based on the big data of user usage habits. During user use, the device records the screen brightness data and ambient light brightness data. After collecting a large amount of user usage data, the corresponding mapping relationship in the data is mined through machine learning algorithms to fit the accurate data internal relationship curve.

[0089] In the embodiment of the present disclosure, an A+G acceleration sensor is used as a sensor for detecting a target posture, and the target posture is wrist raising as an example. The brightness adjustment method of the terminal display screen involved in the embodiment of the present disclosure is described below.

[0090] In one implementation of the disclosed embodiments, when the display screen is in the AOD screen-off display mode, if the brightness changes, the AOD screen-off display brightness cannot be adjusted, affecting the user experience; the A+G acceleration sensor module is called to supplement the brightness adjustment optimization algorithm, and the A+G acceleration sensor module continues to work in all scenarios in the wearable product to complete the collection of consumer step / exercise data. Based on this, for the above scenarios, when the A+G acceleration sensor module detects that the consumer raises his wrist, the light sensor starts the ambient light data capture action, re-collects the ambient light, and completes the brightness data correction.

[0091] In one implementation of the disclosed embodiment, the off-screen display brightness of the terminal depends on the bright screen display brightness. First, the display screen of the terminal enters the AOD off-screen display mode and turns off the light sensor. Second, the most recent bright screen display brightness data of the display screen is retained. Furthermore, according to the following example, Figure 7 The corresponding relationship curve between the off-screen display brightness and the bright-screen display brightness of the display screen shown is used to obtain the off-screen display brightness corresponding to the most recent bright-screen display brightness data of the display screen. Finally, this off-screen display brightness is set as the display brightness of the display screen in the AOD off-screen display mode of the terminal. Taking wearable devices as an example, for example, when the wearable device is worn, after directly entering the off-screen display from the bright-screen display, the system platform of the wearable device transmits data to the AOD off-screen display adjustment module according to the current bright-screen display brightness, and sets the off-screen display brightness data of the wearable device display in the AOD off-screen display mode. When the A+G acceleration sensor module detects the consumer's wrist raising action, the light sensor starts the ambient light data capture action, re-collects the ambient light, and completes the brightness data correction.

[0092] In one implementation of the disclosed embodiment, the screen-off display brightness of the terminal is related to the current motion state. When the terminal is in AOD mode, if the A+G acceleration sensor module detects that the user is in motion, the light sensor appropriately increases the screen-off display brightness of the display screen according to the current ambient light brightness for the user to view. If the A+G acceleration sensor module detects that the user is not in motion, the screen-off display brightness is restored to the original.

[0093] In the disclosed embodiment, the display brightness of the terminal is related to the current target posture / target operation. Taking a mobile phone as an example, for example, the lift-to-light-screen / double-click-to-light-screen function of the mobile phone is set with two options: on and off. When lift-to-light-screen / double-click-to-light-screen is turned on, after the terminal detects the lift / double-click action, it starts the light sensing module to collect ambient light brightness data and exits the AOD mode, and corrects the bright screen display brightness of the display screen through the relationship curve between ambient light brightness and bright screen display brightness. When the AOD screen-off display mode is subsequently entered, the screen-off display brightness of the AOD screen-off display mode is corrected according to the relationship curve between the screen-off display brightness and the bright screen display brightness. When lift-to-light-screen / double-click-to-light-screen is turned off, after the terminal detects the lift / double-click action, it starts the light sensing module to collect ambient light brightness data. The data is directly transmitted to the system platform of the terminal, and the screen-off display brightness of the display screen is corrected according to the relationship curve between the ambient light brightness and the AOD screen-off display brightness.
