Description

Technical Field

[0001] The present disclosure relates to the field of electronic technology, and in particular to a method and device for adjusting display parameters of a display screen, a mobile terminal, and a storage medium. Background Art

[0002] The display is a crucial component of mobile devices. To enhance the user's visual experience, the display operates at varying brightness levels under varying ambient lighting conditions. This reduces visual irritation caused by overly bright displays in low light conditions, and reduces the difficulty of seeing images in bright light conditions due to overly dim displays.

[0003] However, it's worth noting that in related technologies, display brightness adjustment relies on a default brightness curve, which is rigid and doesn't meet practical needs. While displays can achieve adaptive adjustment based on ambient light under certain conditions, the resulting visual effect needs further optimization. Summary of the Invention

[0059] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0060] like Figure 1 As shown, an embodiment of the present disclosure provides a method for adjusting display parameters of a display screen, which is applied to a mobile terminal. The method includes:

[0061] S110: Monitoring the foreground application of the mobile terminal;

[0062] S120: Detecting ambient light in the environment where the mobile terminal is currently located to obtain an attribute value of the ambient light;

[0063] S130: Determine a current display scene based on the monitored attribute values ​​of the foreground application and the ambient light;

[0064] S140: Adjusting display parameters of the display screen according to the current display scene.

[0065] The mobile terminal includes but is not limited to at least one of the following electronic devices: a mobile phone, a tablet computer, a wearable device or an office display device.

[0066] The display screen of the mobile terminal can be classified into a 2D display screen or a 3D display screen according to the form of the display screen. The 3D display screen here at least includes: a waterfall screen, etc.

[0067] It is understandable that the display screen of the mobile terminal can be classified according to the display principle of the display screen, and the display screen can include: a liquid crystal display screen or an organic light emitting diode (OLED) display screen.

[0068] In the embodiment of the present disclosure, the mobile terminal monitors the application running in the foreground. Here, the application running in the foreground is an application opened by the mobile terminal and the application interface is displayed on the display screen.

[0069] Different applications have different display characteristics. For example, gaming applications, video applications, or live streaming applications may have brighter and / or more vibrant colors than other applications (e.g., reading applications) to better meet user expectations.

[0070] For another example, for a reading application, a visual effect that better meets user expectations is: the display interface has a diffuse reflection effect of a paper book and / or a soft display effect.

[0071] Therefore, different applications may expect different visual experience or have different visual characteristics.

[0072] In view of this, moving the currently displayed application is taken into consideration when determining the currently displayed scene.

[0073] In S120, detecting the ambient light of the environment in which the mobile terminal is currently located, and obtaining the attribute value of the ambient light may include at least one of the following:

[0074] Detecting the brightness of the ambient light in the environment where the mobile terminal is currently located to obtain the ambient brightness or ambient illumination;

[0075] Detect the hue of the ambient light in the environment where the mobile terminal is currently located and obtain the chromaticity value of the ambient light.

[0076] Thus, the attribute value of the ambient light includes: an ambient brightness value and / or a chromaticity value; or an ambient illumination value and / or a chromaticity value.

[0077] In the embodiment of the present disclosure, the current display scene can be determined based on the current foreground application of the mobile terminal and the detected attribute value of the switching light. Different display scenes correspond to different basis for adjusting the display parameters of the display screen.

[0078] The display parameters of the display screen corresponding to different display scenes are adjusted based on different criteria, including but not limited to at least one of the following:

[0079] Different display scenes correspond to different brightness adjustment curves;

[0080] Different display scenes correspond to different chromaticity adjustment curves;

[0081] Different display scenes correspond to different contrast adjustment curves;

[0082] Different display scenarios correspond to different adjustment mechanisms of display parameters.

[0083] The above are merely examples of the basis for adjusting the display screen corresponding to different display scenarios, and the specific implementation is not limited to any of the above examples.

[0084] In S130, the program identifier of the application displayed in the foreground of the mobile terminal is used as a query index. Under the multiple display scenes corresponding to the program identifier, the display scene corresponding to the attribute value of the current ambient light is queried to obtain the scene identifier of the current display scene. Based on the scene identifier, the adjustment basis and / or adjustment parameters for adjusting the current display parameters of the display screen are determined.

[0085] The display parameters mentioned in S140 include but are not limited to at least one of the following:

[0086] Display brightness;

[0087] Display chromaticity;

[0088] Contrast.

[0089] In the disclosed embodiments, the display parameters of the display screen are adjusted in conjunction with the mobile terminal's foreground application, rather than simply adjusting the display parameters based on a default adjustment curve or a single attribute value of the current ambient light. The display parameters of the display screen are adjusted based on more physical quantities, enabling more granular adjustments of the display screen under different states, achieving refined adjustments, and improving the visual effects after adjustment. The display parameter adjustments of the display screen performed using the disclosed embodiments are more consistent with the visual effects desired for the current display scene.

[0090] In one embodiment, the method further comprises:

[0091] S101: Detecting the display posture of the mobile terminal during display, and obtaining posture parameters;

[0092] The S140 may include step S141:

[0093] The step S141 may include: when it is determined according to the posture parameter that the display posture of the mobile terminal has changed, determining the current display scene according to the monitored attribute value of the ambient light of the foreground application.

[0094] The posture of the mobile terminal may include at least:

[0095] Horizontal screen display posture when the screen is displayed in landscape mode;

[0096] Portrait display posture when the screen is displayed in portrait mode.

[0097] If a user has been using a mobile terminal and the foreground application on the mobile terminal's display changes, causing a switch in the display scene and further triggering an adjustment to display parameters, the user may notice a noticeable change in the display effect if the current display posture of the mobile terminal has not changed. This may be somewhat surprising to the user, as they may experience an adjustment without triggering the display adjustment. This may feel like an overly strong or noticeable change in the display screen. To further immerse the user in the display services provided by the mobile terminal and minimize or eliminate the user's perception of display parameter adjustments, the display posture of the display is monitored. For example, various sensors on the mobile terminal, including but not limited to inertial sensors such as accelerometers, are used to detect the posture of the mobile terminal. The posture of the mobile terminal during display refers to the posture of the mobile terminal in one state. Based on the acquired posture parameters, it can be determined whether the mobile terminal is rotating or whether the mobile terminal is in the process of switching from one display posture to another or has just completed switching. During the process of adjusting the mobile terminal's display posture, the user's visual focus may be partially distracted by the mobile terminal's posture switch, or after the mobile terminal switches, it may take a short time to recover to the level of focus before the display posture switch. Therefore, in order to achieve the display parameter adjustment being imperceptible or insignificant to the user, the display parameter adjustment can be implemented during the display parameter adjustment process of the mobile terminal or immediately after the adjustment.

[0098] Therefore, the S140 may include:

[0099] According to the posture parameters, during the switching process of the display posture of the mobile terminal, adjusting the display parameters of the display screen according to the current display scene;

[0100] or,

[0101] After the display posture of the mobile terminal is switched according to the posture parameters, the display parameters of the display screen are adjusted according to the current display scene.

[0102] Specifically, the display parameters of the display screen may be adjusted to parameter values ​​corresponding to the current display scene at one time during the display posture switching process of the display screen; or, the display parameters of the display screen may be adjusted to parameter values ​​corresponding to the current display scene immediately after the display posture of the display screen switches.

[0103] In another embodiment, the method further comprises:

[0104] When the display scene of the mobile terminal has changed, and it is determined based on the self-parameters that the display posture of the mobile terminal has not changed or it is predicted that the display posture of the mobile terminal has a probability value greater than a probability threshold and has not changed, the display parameters of the display screen are adjusted step by step to parameter values ​​corresponding to the current display scene according to a first adjustment step.

[0105] The first adjustment step may be a pre-configured adjustment value that is not noticeable or barely noticeable to the user's vision.

[0106] Through this adjustment method, the display parameters of the display screen can be gradually adjusted to correspond to the current display scene, and the gradual adjustment will reduce the obvious change in display effect felt by the user before and after a one-time adjustment.

[0107] One-time adjustment and step-by-step adjustment are two different adjustment methods for adjusting the display parameters of a display screen, and can be applied to different display scenarios of the display screen.

[0108] In one embodiment, when determining according to the posture parameter that the display posture of the mobile terminal has changed, determining the current display scene according to the monitored attribute value of the ambient light of the foreground application includes:

[0109] When it is determined according to the posture parameter that the display switches from the portrait posture to the landscape posture, the current display scene is determined according to the monitored attribute value of the ambient light of the foreground application.

[0110] It can be explained that the S130 may include:

[0111] If the current foreground application of the mobile terminal is a preset application, the current display scene is determined according to the preset application and the attribute value of the ambient light.

[0112] The preset application can be an application in a list, such as an application in a whitelist. If the current foreground application on a certain terminal is an application whose program identifier is in the whitelist, the current display scene is determined based on the damaged application and the currently detected ambient light attribute value. Otherwise, the current display scene can be determined directly based on the ambient light attribute value; alternatively, the display parameters of the display screen can be adjusted directly based on the ambient light attribute value.

[0113] Optionally, the preset application and the non-preset application other than the preset application may be two types of application having different display characteristics or expected visual effects.

[0114] For example, a preset application may have display characteristics or desired display effects that are significantly different from those of other applications.

[0115] For gaming applications, the requirements for color saturation or display switching frame rate may be significantly different from those for ordinary browser applications.

[0116] For another example, the preset applications include: video applications; video applications use video broadcasting as their main business. At this time, the audience may have higher requirements for color saturation or color fidelity, which is different from browser applications or social applications. If the foreground application of the display is a video application, it is necessary to additionally determine the basis for adjusting the display chromaticity, color saturation and / or contrast.

[0117] Of course, different preset applications have different display characteristics or expected display effects.

[0118] Therefore, in some embodiments, non-default applications may be applications that can share the same or similar adjustment basis.

[0119] In some embodiments, the S140 may include:

[0120] Determining a brightness curve according to the current display scene;

[0121] The brightness of the display screen is adjusted according to the brightness curve.

[0122] The display parameters of the display screen include display brightness, and the visual effect corresponding to the display brightness is the change between light and dark of the display screen.

[0123] In the embodiment of the present disclosure, the brightness curve is determined according to the current display scene, rather than directly according to the properties of the ambient light.

[0124] For example, if the foreground application on a mobile terminal is a game application, and the display brightness required by the game application, determined by pre-configuration or other means, is higher than that required by other applications, the demand for the required display brightness will be reflected in the current display scene, and a brightness curve that increases the display brightness of the display screen will be selected. Compared with non-preset applications (or ordinary applications), when the mobile terminal displays a game application in the foreground, the curve selected for adjusting the display brightness according to the attribute value of the ambient light will have a higher display brightness value on the brightness curve under the same ambient light brightness.

[0125] In some embodiments, the brightness curve comprises: forming a curve through a series of brightness values. The unit of these brightness values ​​may be nits (NIT).

[0126] In some embodiments, the brightness curve may be pre-configured in the mobile terminal, or may be received by the mobile terminal from a network side, for example, the mobile terminal receives it from a manufacturer's server.

[0127] In other embodiments, the brightness curve may also be generated based on historical display brightness values ​​of the mobile terminal itself, foreground applications, and attribute values ​​of ambient light at historical moments.

[0128] In some embodiments, the brightness curve is determined based on brightness adjustment behavior data of multiple terminals.

[0129] For example, the brightness curve is generated based on the brightness adjustment behavior data of a large number of terminals. A server on the network side can receive reports of the brightness adjustment behavior data of the mobile terminals themselves. In this way, the server on the network side can perform big data processing based on the brightness adjustment behavior data reported by a large number of mobile terminals, thereby obtaining statistical data on the display brightness adjustment performed by a large number of terminals, and forming the brightness curve that can cover the display brightness requirements of users of a large number of mobile terminals. The curve can then be distributed to the mobile terminals regularly or irregularly for use by the mobile terminals.

[0130] In some embodiments, the method further comprises:

[0131] The display parameter adjustment behavior data of the display screen (for example, including but not limited to brightness behavior adjustment data) is collected and marked; and the collected display parameter adjustment behavior data is then reported to the server.

[0132] For example, reporting to the server periodically or aperiodically. Aperiodic reporting here includes: reporting to the server when the amount of collected display parameter adjustment behavior data reaches a reporting threshold; or reporting collected and not yet reported display parameter adjustment behavior data to the server upon receiving a reporting instruction from the server.

[0133] In this way, the display parameter adjustment behavior data collected and reported by the mobile terminal can be used by the server to generate an adjustment basis for adjusting the display parameters of the display screen for different display scenarios based on big data, such as a display parameter adjustment curve or a display parameter adjustment function.

[0134] In some embodiments, the method further includes: determining, based on the attribute value of the ambient light, whether the ambient brightness of the environment in which the mobile terminal is currently located meets an adjustment condition;

[0135] The S140 may include: when the ambient brightness of the environment in which the mobile terminal is currently located meets the adjustment condition, adjusting the display brightness of the display screen according to the current display scene.

[0136] In some cases, adjusting the display brightness can improve the display effect, but the improvement is not very obvious. In order to reduce the power consumption caused by unnecessary or frequent adjustments, the present disclosure also determines whether the ambient brightness of the environment in which the mobile terminal is currently located meets the conditions based on the attribute value of the ambient light. If the conditions are met, it means that the current adjustment has significantly improved the visual effect, and step S140 is executed. Otherwise, step S140 may not be executed.

[0137] The ambient brightness adjustment condition includes but is not limited to at least one of the following:

[0138] The ambient brightness is lower than a brightness threshold;

[0139] The ambient brightness is lower than the brightness threshold, and a change in the brightness value of the ambient brightness within a preset time period including the current time is less than a fluctuation threshold.

[0140] In some embodiments, adjusting the display parameters of the display screen according to the current display scene includes:

[0141] Adjust the contrast of the display screen according to the current display scene.

[0142] For example, in a display scenario where a reading application is the foreground application, excessive contrast may create a glaring visual effect, so the contrast can be appropriately reduced. Therefore, according to the embodiment of the present disclosure, the display parameters of the display screen are not limited to display brightness, but can also include display contrast, etc.

[0143] The present disclosure provides a method for adjusting a display screen, and the specific operations may be as follows:

[0144] Many applications (apps) are downloaded onto mobile devices, such as smartphones. For example, many apps were previously downloaded onto mobile devices running the Android operating system. Due to the differences in functionality of these apps, users may have different requirements for display brightness. For example, when playing games or watching videos, users may have different requirements for display brightness or color saturation.

[0145] The following description takes the brightness adjustment of a display screen as an example, but the specific implementation is not limited to brightness adjustment.

[0146] The technical solution provided by the embodiments of this disclosure involves dynamically adjusting the default brightness curve based on the specific app running in the foreground of a mobile terminal. This brightness curve is different from the default brightness curve. Instead, it is a functional curve fitted based on big data collected from the brightness adjustment behavior of the mobile terminal when using the specific app. Based on this functional curve, a brightness that better suits the user's current usage scenario is output, thereby improving the brightness user experience of the mobile terminal.

[0147] When the mobile terminal is started, the display screen will show that this technical solution will start to monitor the switching of the user's foreground app and the change of the device rotation direction in the background. When the app displayed in the foreground is in the whitelist of curves that need to be switched and the rotation direction of the display screen is horizontal, it will again determine whether the current lux meets the threshold. If it does, it will switch to the fitted scene curve to modify the brightness.

[0148] This technical solution will identify the specific display scene of the mobile terminal by registering the foreground App listener and the rotation listener of the display screen.

[0149] Combined with the foreground application monitoring and the display rotation monitoring, it can accurately identify the real display scenario currently in use, and adjust the display parameters of the display according to the data reported to the processor by the monitor.

[0150] For apps in the whitelist, the system sends a notification message to the BrightnessMAppingStrategy class, which is responsible for creating and switching brightness curves.

[0151] When the BrightnessMAppingStrategy class receives this notification message, it will again determine whether the current ambient light brightness meets the threshold. If it does, it will switch to the fitted current display scene and modify the display brightness to adjust the currently used brightness curve.

[0152] In one feasible embodiment, during daily use of a mobile terminal, the program code of the mobile terminal is instrumented to collect data on the user's brightness adjustment behavior. After collecting massive amounts of user data, the brightness adjustment behavior data is analyzed from multiple dimensions, such as the foreground app, the current ambient light attribute value, the current display brightness, the brightness value of the adjusted display, and / or the combination of landscape and portrait screens, to fit a brightness curve that suits most users. This curve is used to replace the default brightness curve when the preconditions are met, thereby solving the user's pain point of brightness not meeting expectations in certain usage scenarios.

[0153] When watching videos or playing games on a mobile device in dim ambient light, if the point light source is on the back of the phone or the light source is dim, the default curve often gives a dim brightness, making it difficult to see the content on the display, forcing the user to manually adjust the brightness. This technical solution eliminates the need for active user adjustment in this scenario, directly providing the brightness that suits the user and improving the user experience.

[0154] like Figure 3 As shown, the brightness adjustment method of a display screen provided by the embodiment of the present disclosure may include:

[0155] Monitor the front-end APP of the mobile terminal;

[0156] Monitoring the rotation of the mobile terminal, for example, based on monitoring whether the mobile terminal is currently in a landscape or portrait state;

[0157] Monitor the ambient brightness of the mobile terminal's current environment and determine whether it meets a threshold, for example, whether it is below a threshold;

[0158] Collect brightness adjustment behavior data and determine the brightness curve for adjusting the display brightness in different display scenarios;

[0159] Dynamically adjust the brightness curve based on the predetermined brightness curve, the app monitored in the foreground, the posture of the mobile terminal and the current ambient brightness;

[0160] The display screen dynamically switches brightness according to the adjusted brightness curve.
