Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Along with the rapid development of the internet of things technology, the interaction demand of a user on intelligent equipment is higher and higher, particularly, in an application scene of an intelligent home, the user often performs regulation and control on networking equipment through intelligent equipment such as a control panel of a wall surface and a control end of a desktop, and in order to facilitate the user to check the running state of each networking equipment through a display panel of the intelligent equipment or execute related regulation and control operations, the display panel of the intelligent equipment generally performs display in a normally bright mode.
However, the above display scheme undoubtedly brings a large power consumption burden and occupies too much system processing resources. In order to solve the above technical problem, one solution in the prior art is to close the display panel after the user completes execution of the relevant control operation and waits for a period of time, and if the user needs to check the running state or execute the relevant control operation, trigger the smart device again to light the display panel. However, the above solutions sacrifice user experience in order to achieve power consumption saving, and a user cannot check an operating state or execute related regulation and control operations in time, and a processing manner of directly turning off a display panel does not meet the practical requirements under the existing smart home environment, and cannot provide a display panel brightness control scheme with more balanced device power consumption, heat productivity and convenience in use for the user.
Therefore, the inventor proposes a method for controlling brightness of a display panel of a smart device, a smart device and a computer-readable storage medium provided by the embodiment of the present application, in which the display panel is lighted when a user interacts with the smart device; then, when the user stops interacting with the intelligent device, timing is started; if the interaction instruction of the user is not received after the preset duration is reached, the brightness of the display panel is reduced to a preset brightness value according to the time period, wherein the brightness value is not zero, so that the brightness of the display panel can be accurately and timely adjusted, a display panel brightness control scheme with more balanced equipment power consumption, heat productivity and use convenience is realized, and the user experience is enhanced.
Example one
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for controlling brightness of a display panel of an intelligent device according to an embodiment of the present application. The embodiment provides a method for controlling the brightness of a display panel of an intelligent device, which comprises the following steps:
and S1, lighting the display panel when the user interacts with the intelligent equipment.
In this embodiment, when the smart device detects that the user is in the process of interacting with the smart device, in order to provide better interaction experience for the user, at this time, the display panel of the smart device is lit up according to a preset brightness display scheme. The interaction between the user and the intelligent device comprises voice interaction, gesture interaction and touch interaction. In the process of interaction between a user and one intelligent device, if the related function can be linked with other intelligent devices in the moving direction according to the movement of the user, correspondingly, the other intelligent devices are determined to be in the interaction process with the user, and simultaneously or sequentially lightening the display panels of the other intelligent devices according to the moving direction. Optionally, in this embodiment, when the display panel of the smart device is made of a display material made of a self-luminous material, in order to further achieve balance among power consumption, heat generation amount, and convenience of use of the smart device, when it is detected that a user is in the process of interacting with the smart device, a type of interaction or a type of a function to be executed is determined, so that a local display area related to the type of interaction or the type of the function to be executed is determined in one entire display area of the display panel, and a requirement of the user for interacting with the smart device is met by lighting only the local display area. Further, in this embodiment, when the entire display area of the display panel is in a low-brightness standby display state, if it is detected that the user is in the process of interacting with the smart device, the requirement of the user for interacting with the smart device is met by increasing the brightness of the local display area.
And S2, starting timing when the user stops interacting with the intelligent device.
In this embodiment, in order to avoid the problems of power consumption of the device, heat generation of the device, and the like caused by lighting the display panel for a long time, when the user stops interacting with the smart device, the display brightness of the display panel starts to be lowered. In this embodiment, in consideration of a real usage scenario that a user may perform some interactive operations multiple times or at intervals in a short time, therefore, in order to avoid inconvenience of subsequent use for the user caused by immediately turning down the display brightness of the display panel when the user stops interacting with the smart device, this embodiment starts timing when the user stops interacting with the smart device, that is, determines a stop duration after the user stops interacting with the smart device by means of subsequent timing, so as to facilitate dynamically and adaptively adjusting and controlling the brightness of the display panel according to the stop duration. Specifically, in this embodiment, whether the user has stopped interacting with the smart device, that is, whether the user has stopped sending a voice signal, a gesture signal, or a touch signal to the smart device, may be detected by a distance sensor, an ultrasonic sensor, a light sensor, a temperature sensor, a screen pressure sensor, a screen component, a microphone component, and the like of the smart device. Optionally, in this embodiment, the end time of the last voice signal, or gesture signal, or touch signal sent to the smart device by the user is used as the timing start point of this embodiment.
And S3, if the interaction instruction of the user is not received after the preset duration, reducing the brightness of the display panel to a preset brightness value according to the time period, wherein the brightness value is not zero.
In this embodiment, after the timing is started from the timing start point, if the interactive instruction of the user is not received within a preset time period, it is determined that some other interactive operations may not be executed for multiple times or at intervals within a short time period, and at this time, the brightness of the display panel is reduced to a preset brightness value according to the time period of the timing start point, where the brightness value is not zero. Specifically, in this embodiment, first, a time length for determining whether the user will perform some other interactive operations multiple times or at intervals in a short time is preset, for example, the time length is fifteen seconds, when the user stops interacting with the smart device, timing is started, if the timed time length reaches fifteen seconds, timing is continued, and a time period in which the timed time length is located is determined. In this embodiment, a plurality of time periods are preset, for example, each time period is the same fifteen seconds, and when the time period of the timing is forty seconds, it is determined that the timing is in the second time period. In this embodiment, the preset time periods are intended to determine the corresponding brightness values respectively by determining the time period of the timing duration, that is, when the timing duration is forty seconds, determining that the timing duration is in the second time period, and further reducing the brightness of the display panel to the brightness value corresponding to the second time period. It is to be understood that, in order to avoid inconvenience to the user in the next use due to complete screen blanking, in the present embodiment, the corresponding luminance values are successively decreased in the ascending order of the time period, but the lowest luminance value is kept non-zero.
The method has the advantages that the display panel is lightened when the user interacts with the intelligent device; then, when the user stops interacting with the intelligent device, timing is started; if the interaction instruction of the user is not received after the preset duration is reached, the brightness of the display panel is reduced to a preset brightness value according to the time period, wherein the brightness value is not zero, so that the brightness of the display panel can be accurately and timely adjusted, a display panel brightness control scheme with more balanced equipment power consumption, heat productivity and use convenience is realized, and the user experience is enhanced.
Example two
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for controlling brightness of a display panel of an intelligent device according to another embodiment of the present application. In this embodiment, in order to further determine that the display panel is lit when the user interacts with the smart device, this step includes:
and S11, determining the default brightness value when the display panel is lightened according to the display parameters.
In this embodiment, the default brightness value may be a fixed brightness value set by the factory of the intelligent device or actively set by the user; alternatively, the default brightness value may be a dynamic brightness value determined according to historical operating state information of the smart device, for example, the dynamic brightness value is obtained according to one or more of a historical system operating power consumption state, a historical processor heating state, and a historical display power consumption state of the smart device; or, the default brightness value may also be a dynamic brightness value determined according to a setting parameter of a display panel of the smart device and the current ambient light intensity.
S12, when the operation state of the intelligent device is detected to be high-power operation, the display panel is lightened by a brightness value lower than the default brightness value, and when the operation state of the intelligent device is detected to be low-power operation, the display panel is lightened by a brightness value higher than the default brightness value.
In this embodiment, the default brightness value is dynamically adjusted according to the current operating state of the smart device, that is, for the scheme for determining the default brightness value, the step is to obtain the corresponding brightness value according to the current operating state. For example, when the default brightness value is a dynamic brightness value determined according to historical operating state information of the intelligent device for one week or one month, on the basis, the operating state of the lighting current time is obtained, and a corresponding brightness value is determined according to the operating state.
In this embodiment, the corresponding power state is determined according to the processor occupancy rate in the current operation state, that is, when the processor occupancy rate is high, for example, the processor occupancy rate is greater than a preset threshold, the current operation state is determined to be high-power operation, and conversely, when the processor occupancy rate is low, the current operation state is determined to be low-power operation.
Optionally, the corresponding power state is determined according to the power output of the power management chip in the current operating state, that is, when the power output is high, for example, the power output is greater than a preset threshold, the current operating state is determined to be high-power operation, and conversely, when the power output is low, the current operating state is determined to be low-power operation.
Optionally, the corresponding power state is determined according to the number of active processes in the current operation state, that is, when the number of active processes is high, for example, the number of active processes is greater than a preset threshold, the current operation state is determined to be high-power operation, and conversely, when the number of active processes is low, the current operation state is determined to be low-power operation.
Optionally, the corresponding power state is determined according to the task execution state in the current operation state, that is, when the task execution state is not completed, the current operation state is determined to be high-power operation, otherwise, when the task execution state is completed or no task is currently executed, the current operation state is determined to be low-power operation.
S12', or, when it is detected that the temperature value of the smart device is greater than a preset temperature value, light the display panel with a brightness value lower than the default brightness value, and when it is detected that the temperature value of the smart device is less than the preset temperature value, light the display panel with a brightness value higher than the default brightness value. In this embodiment, the default brightness value is dynamically adjusted according to the current temperature value of the intelligent device, that is, according to the scheme for determining the default brightness value, the step is to obtain the corresponding brightness value according to the current temperature value. For example, when the default brightness value is a dynamic brightness value determined according to the historical temperature information of the smart device in the same time period (e.g., noon, morning, night, etc.), on the basis, a temperature value at the current lighting time is obtained, and a corresponding brightness value is determined according to the temperature value.
Optionally, in this embodiment, if a trigger signal of the user to the smart device is detected, the display panel is illuminated, where the trigger signal includes one or more of a voice signal, a gesture signal, and a touch signal. Specifically, for the same smart device, the voice signal, the gesture signal, and the touch signal do not distinguish whether the same user triggers the same smart device, that is, when multiple users send one or more of the voice signal, the gesture signal, and the touch signal to the same smart device for multiple times or at intervals, it is determined that the display panel of the smart device needs to be lit. Optionally, in this embodiment, when it is detected that one smart device receives one or more of the voice signal, the gesture signal, and the touch signal, the method continues to monitor whether the execution of the one or more of the voice signal, the gesture signal, and the touch signal is completed, if not, monitors the moving direction of the user, and determines whether there is another smart device in the moving direction that can continue to execute the one or more of the voice signal, the gesture signal, and the touch signal that is not completed, and if so, when the user exceeds the range of the previous smart device, and/or enters the range of the next smart device, the display panel of the next smart device is lit up, and the display panel of the next smart device is ready to receive the one or more of the voice signal, the gesture signal, and the touch signal that are not completed, so as to implement the linked lighting of the multi-device display panels, and bring more consistency to the user, A seamless interactive experience.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for controlling brightness of a display panel of an intelligent device according to another embodiment of the present application. In this embodiment, before starting timing when the user stops interacting with the smart device, the method includes the steps of:
and S21, determining the preset time length according to the function required to be executed by the intelligent equipment during interaction and/or the signal type of the trigger signal.
In this embodiment, in order to avoid inconvenience brought to current use or next use of the user by immediately turning down the screen brightness value when the interaction is stopped, in this embodiment, the preset duration is determined according to a function to be executed by the smart device and/or a signal type of the trigger signal during the interaction. Specifically, the preset time period is dynamically determined according to the function to be executed and/or the signal type of the trigger signal. For example, when the function to be executed is a single function such as turning on and off a light, a short preset time period is determined, and when the function to be executed is a plurality of functions such as regulating and controlling the operating parameters of the air conditioner, a long preset time period is determined; for another example, when the trigger signal is a voice signal, a longer preset duration may be determined in consideration of the fact that the voice signal may involve multiple continuous voices, and when the trigger signal is a touch signal, a shorter preset duration may be determined in consideration of the fact that the touch signal triggers the feature in time.
And S22, sequentially presetting a plurality of time periods from short to long after the preset time length.
It can be seen that, in the above embodiment, the preset time periods are aimed at determining the corresponding brightness values respectively by determining the time periods in which the timing durations are located, but the time periods set by the above scheme are the same and not completely in accordance with the interaction interval habits of users, so that in this embodiment, after the preset time period, a plurality of time periods from short to long are preset in sequence. For example, the first time period is five seconds, the second time period is ten seconds, the third time period is fifteen seconds, and the like, and on this basis, when the time length of the timing is forty seconds, the timing is determined to be in the third time period.
And S23, respectively determining a plurality of corresponding preset brightness values from high to low according to the plurality of time periods from short to long.
In this embodiment, it is considered that the foregoing embodiment proposes to preset a plurality of time periods, for example, each time period is the same fifteen seconds, each corresponding time period corresponds to a decreasing brightness value, and the time span of the decreasing brightness is uniform and does not conform to the interaction distribution state of the user in a certain period, so that the embodiment sequentially preset a plurality of time periods from short to long, and thus respectively determine a plurality of corresponding preset brightness values from high to low according to the plurality of time periods from short to long. Likewise, for example, a first time period of five seconds, a second time period of ten seconds, a third time period of fifteen seconds, etc., meanwhile, the first period is 80% of the previous brightness value, the second period is 80% of the previous brightness value, the third period is 80% of the previous brightness value, etc., or the first period is 80% of the previous brightness value, the second period is 70% of the previous brightness value, the third period is 60% of the previous brightness value, etc., on the basis, when the time length of the timing is forty seconds, the timing is determined to be in a third time period, the brightness value is adjusted three times in turn by 80 percent of the previous brightness value, alternatively, the luminance value adjustment is performed once by 80% of the previous luminance value, the second adjustment is performed by 70% of the adjusted luminance value, and the third adjustment is performed by 60% of the adjusted luminance value in this order.
Optionally, in this embodiment, when the user stops interacting with the smart device, starting timing includes the steps of: and when receiving the instruction corresponding to the function and/or the trigger signal and delaying for a preset time, determining that the user stops interacting with the intelligent device and starting timing. In this embodiment, after the user interacts with the smart device, there is a period of reaction, execution, or waiting time in the stages of function execution, initialization, and the like involved in the process of this interaction, and in this period of time, the function initialization needs some time, some intermediate information may be displayed on screen, some feedback information of execution may be reminded by sound, and the like. Therefore, after receiving the instruction corresponding to the function and/or the trigger signal and delaying the preset time, it is determined that the user has stopped interacting with the smart device and starts the timing, that is, when the user sends the last voice signal, or gesture signal, or touch signal to the smart device, the timing is started after delaying the preset time. For example, if the delay time is five seconds, when the last voice signal, gesture signal, or touch signal sent to the smart device by the user is delayed for the preset five seconds, and then, if it is monitored that the user still does not interact with the smart device within the next fifteen seconds, timing is started.
Optionally, in this embodiment, when the user stops interacting with the smart device, starting timing includes the steps of: and when receiving an instruction corresponding to the function and/or the trigger signal and monitoring that the user exceeds the preset distance range of the intelligent device, determining that the user stops interacting with the intelligent device and starting timing. Specifically, in this embodiment, when the user sends one or more of the voice signal, the gesture signal, and the touch signal to the smart device, it is determined whether the execution of the one or more of the voice signal, the gesture signal, and the touch signal is completed, if the execution of the one or more of the voice signal, the gesture signal, and the touch signal is in the process of being executed but not completed, it is monitored whether the user is beyond a preset distance range of the smart device, and if the user is beyond the preset distance range of the smart device and waits for a preset time, the user is still not within the distance ranges of other associated smart devices, it is determined that the user has stopped interacting with the smart device, and the timing is started. Optionally, if it is determined that one or more of the voice signal, the gesture signal, and the touch signal are executed, timing is started when the monitoring user exceeds the preset distance range of the smart device. Optionally, if it is determined that one or more of the voice signal, the gesture signal, and the touch signal are executed, when it is monitored that the user exceeds the preset distance range of the smart device and returns to the preset distance range of the smart device at intervals, it is determined whether the time away from the distance range reaches another preset time length, and if not, timing is not started.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for controlling brightness of a display panel of an intelligent device according to another embodiment of the present application. In this embodiment, if the interaction instruction of the user is not received after the preset duration, reducing the brightness of the display panel to a preset brightness value according to the time period, where the brightness value is not zero, includes:
and S31, determining the current time length of the interactive instruction of the user which is not received yet according to real-time timing.
In this embodiment, as described in the above example, in order to avoid inconvenience to the current use or the next use of the user due to the instant reduction of the screen brightness value when the interaction is stopped, in this embodiment, the preset duration is determined according to the function to be executed by the smart device during the interaction and/or the signal type of the trigger signal. Specifically, the preset time period is dynamically determined according to the function to be executed and/or the signal type of the trigger signal. For example, when the function to be executed is a single function such as turning on and off a light, a shorter five-second time period is determined, and when the function to be executed is a plurality of functions such as regulating and controlling the operating parameters of the air conditioner, a longer ten-second time period is determined; for another example, when the trigger signal is a voice signal, the longer fifteen second duration is determined in consideration of the fact that the voice signal may involve multiple continuous voices, and when the trigger signal is a touch signal, the shorter three second duration is determined in consideration of the fact that the touch signal triggers the feature in time.
S32, if the current time length exceeds the preset time length, determining the time period of the current time length in real time.
In this embodiment, as described in the above example, it is considered that the above embodiment proposes to preset a plurality of time periods, for example, each time period is the same fifteen seconds, each corresponding time period corresponds to a decreasing brightness value, and the time span of the decreasing brightness is uniform and does not conform to the interaction distribution state of the user in a certain period, so that the embodiment preset a plurality of time periods from short to long in sequence, and thus respectively determine a plurality of corresponding preset brightness values from high to low according to the plurality of time periods from short to long. Similarly, for example, the first time period is five seconds, the second time period is ten seconds, the third time period is fifteen seconds, and the like, and on this basis, when the length of the timing is forty seconds, it is determined that the timing is in the third time period.
And S33, adjusting the brightness of the display panel to the preset brightness value corresponding to the time period.
