The present application claims priority to Chinese Patent Application No. 201910394091.4, filed May 13, 2019, which is herein incorporated by reference in its entirety.
The present invention relates to the technical field of electronic devices, and particularly to a scalable displaying method, a mobile device and a storage medium for power savings in mobile devices.
Mobile device displays are a significant consumer of mobile device power. As a result, mobile devices oftentimes provide a “lower power mode” or “low battery mode” to reduce power consumption on the mobile device. Typically, with respect to the mobile device display, these power saving modes have included operating the display at a reduced brightness so that less power is consumed for operating the display. However, the effect of power saving in such a manner is not good enough. When a user expects to prolong service time of the mobile device, a desired result often cannot be obtained in such a manner
The present disclosure provides a scalable display to reduce power consumption on the mobile device. The display is scaled by activating only a portion of the screen of the mobile device for use as the display, such that an overall power consumed by the screen is reduced. The scalable display of the present disclosure may or may not be used in combination with the known technique of reducing display brightness to reduce power consumption.
According to one aspect of the present disclosure, a method is provided, comprising:
receiving an instruction to scale a display of a mobile device; and
scaling the display on a screen of the mobile device in response to the instruction.
According to another aspect of the present disclosure, a mobile device is also provided, comprising:
one or more processors;
one or more memories for storing one or more computer programs;
when the one or more computer programs are executed by the one or more processors configuring the mobile device to perform operations comprising:
receive an instruction to scale a display of a mobile device; and
scale the display on a screen of the mobile device responsive to the instruction.
According to yet another aspect of the present disclosure, a storage medium is also provided on which a computer program is stored. When the computer program is operated by at least one processor, the at least processor implements the method according to one aspect of the present disclosure.
A scalable displaying method, a mobile device and a storage medium for power saving in mobile devices according to the present disclosure, scale the display by activating only a portion of the screen of the mobile device for use as the display, such that an overall power consumed by the screen is reduced, which may therefore prolong service time of the mobile device.

One or more computer program instructions may be stored on the computer readable storage medium. The processor 102 may run the program instructions to realize the client functions in the embodiments of the present invention (realized by the processor) as described below and/or other desired functions. Various application programs and data may be also stored in the computer readable storage medium, such as the various data used and/or generated by the application programs, and the like.
The input/output device 106 may be a device with which a user inputs instructions and outputs various information outwards. For instance, the input device may comprise one or more of a keyboard, a mouse, a microphone and a touch screen, and the like. The output device may comprise one or more of a display and a loudspeaker, etc.
The communication interface 108 broadly represents an adaptor or a communication device of any type or form which can promote communication between the exemplary electronic device 100 and one or more auxiliary devices. For instance, the communication interface 108 may promote communication of the electronic device 100 with a front-end or an accessory electronic device and a back-end server or the cloud. The example of the communication interface 108 comprises but is not limited to a wired network interface (e.g. a network access card), a wireless network interface (e.g. a wireless network interface card), a modem and any other suitable interfaces. In one embodiment, the communication interface 108 provides direct connection to a remote server/remote front-end device through a direct connection with the network such as Internet.

The display device 110 may further comprise a display controller such as a LCD controller for controlling/driving the display of the display device 110, e.g. brightness, refresh rate of the display device, to drive the display device 110 to display the specific colors and contents.
Exemplarily, the exemplary electronic device for implementing the scalable displaying method and the mobile device according to embodiments of the present disclosure may be realized as portable electronic devices or battery powered electronic devices such as a smart phone, a tablet computer, a laptop, and the like.
With reference to
In step S202, an instruction to scale a display of a mobile device is received. In the context of the present method, scaling the display includes down-sizing the display of the mobile device for presentation on just a portion of the entire screen of the mobile device, such that a remaining portion of the screen of the mobile device (not showing the display) is deactivated for power saving purposes. Thus, in the context of the present description, the display refers to the graphical user interface (GUI) presented on an activated (e.g. illuminated. etc.) portion of the screen of the mobile device for viewing by a user of the mobile device.
In one embodiment, the instruction may be triggered automatically based on the battery status of the mobile device. For example, the instruction may be triggered when the battery reaches a threshold level. The threshold level may be predefined and/or configured by a user of the mobile device. In another embodiment, the instruction may be triggered on-demand by the user of the mobile device selecting an option to scale the display (e.g. a sliding tool with values ranging from 0% to 100% of the original size of the display), or selecting an option to operate the mobile device in a reduced power consumption mode that includes operating with a scaled down display.
In another embodiment, the instruction may indicate an amount to scale the display of the mobile device. The amount may be a percentage of an original size of the display. For example, the amount may be 75%, 50%, or 25% of the original size of the display or a full size of the screen of the mobile device. As an option, the amount to scale the display may be a function of the battery status of the mobile device. Thus, as the battery level of the mobile device decreases, the display size may also be decreased. As another option, the amount to scale the display may be selected by the user of the mobile when selecting the option to scale the display, as described above.
In one embodiment, the instruction may indicate an area of the screen to present the scaled display, or in other words the area of the screen to be activated. For example, the scaled display may be centered on the screen of the mobile device. As another example, the scaled display may be top left-justified on the screen of the mobile device. It should be noted that centering the scaled display on the screen may require more mathematical calculations than top-left justifying the scaled display on the screen in order to determine equal left/right and equal top/bottom portions of the screen to deactivate.
In step S204, the display of the mobile device is scaled on the screen in response to the instruction. The display may be scaled by the amount indicated by the instruction, or a predefined amount, thereby reducing a resolution of the display. Since the active area of the screen is reduced, less power is consumed by the screen (that is, the power consumed by the screen is reduced).
In one embodiment, the display of the mobile device is scaled via a screen controller (e.g. liquid crystal display (LCD) controller) and a graphics processing unit (GPU) of the mobile device. The screen controller and the GPU are notified of the instruction to scale the display. As a result, the GPU outputs the scaled display (i.e. scaled GUI) and the screen controller sends the scaled display to only the area of the screen to be activated. In the present embodiment, the portion of the screen is activated by turning ON a portion of a backlight of the mobile device corresponding to the portion of the screen, for presenting the scaled display on the screen for viewing by the user. The remaining portion of the backlight is turned OFF for deactivating a remaining portion of the screen.
Further to the above embodiment, timing configuration settings of the screen controller may be updated. The timing configuration settings may be updated only for the portion of the screen to be deactivated, to at least temporarily prevent the screen controller from sending pixel data to the portion of the screen to be deactivated, or otherwise reduce the frequency at which the screen controller sends pixel data to the portion of the screen to be deactivated.
In another embodiment, particularly where the screen is an organic light-emitting diode (OLED) screen that is already configured for selectively activating a backlight for portions of a screen, the scaling of the display and the control of the backlight may be provided using the GPU (e.g. without any hardware changes required for the screen controller as otherwise required in the embodiment described above). In particular, in response to the instructions, the GPU may output pixel data for an entire area of the screen ,wherein the pixel data for the portion of the screen to be activated presents the scaled-down display and the pixel data for the portion of the screen to be deactivated is black. By the GPU driving the back to the portion of the screen to be deactivated, the OLED screen will automatically deactivate the backlight for that portion of the screen, thus providing power saving.
In this embodiment, the scaled display, which is implemented according to the present disclosure, is described by taking the laptop 300 as an example. The electronic device 100 as shown in
In the present embodiment, the scaled display of the laptop 300 is triggered by function key Fn308 and FX310 on the keyboard of the laptop 300. For example, the function keys Fn+F8 are configured when it is pressed down, the scaled display of the laptop 300 is triggered. Certainly, the scaled display of the laptop 300 may also be triggered by other manners, e.g. by control options of the display device 304 or other setting options. When the options of the configured laptop 300 is triggered, an instruction to scale the display is received by the graphics processing unit (GPU) 302 and the LCD controller 306 of the laptop 300. The graphics processing unit (GPU) 302 subsequently outputs the scaled display (i.e. the scaled GUI), and the screen controller 306 sends the scaled display only to an area of the display device 304 to be activated. In this embodiment, the area of the display device 304 to be activated is configured in a top left-justifying manner That is, if the size of the scaled display is ¼ of the original size, the top-left ¼ area of the display device 304 is an area to be activated. If the size of the scaled display is ½ of the original size, the top-left ½ area of the display device 304 is an area to be activated. As illustrated above, the percentage of the scaled display may be included in a triggering instruction of the scaled display. As an example, after the function keys Fn+F8 are pressed down, the instruction to scale the display is triggered, and meanwhile the instruction further indicates that the percentage of the scaled display is ½. In the embodiment, the function keys Fn+F8 may be further configured to trigger a further scale display instruction when it is pressed again, for instance, the percentage to scale the display changes from ½ to ¼.
In the embodiment, as illustrated above, the display device 304 is activated by turning ON a portion of the backlight corresponding to the portion for presenting the scaled display. The remaining portion of the backlight is turned OFF for deactivating the remaining portion of the screen. Thus, the deactivated portion of the display device 304 is electrically turned OFF to reduce power consumption by the display device 304 and prolong the usage time of the battery of the laptop 300. As an example, if the display device 304 consumes 50% power of the entire system of the laptop 300, and if the display device 304 is operated with a ½ scaled display at 100% power supply level, the working time of the laptop 300 may prolong 33.3%; if the display device 304 is operated with a ¼ scaled display at 100% power level, the working time of the laptop 300 may prolong 60%.
It should be appreciated that in this embodiment, the function keys Fn308 and FX310 as an option to trigger the scaled display are exemplary but not limited. The percentage of the scaled display is also exemplary but not limited. Those skilled in the art may make suitable configuration as needed. For example, as explained above, the laptop 300 may be configured to trigger an instruction to scale the display when its battery level is below a threshold level, such as below 20%. For another example, when the laptop 300 enters a lower power mode, an instruction to scale the display is triggered.
It should be further appreciated that in the embodiment, although the display is scaled by electrically turning OFF a portion of the backlight of the display device 304 to reduce power consumption of the display device 304 and prolong the usage time of the battery of the laptop 300, it may or may not be used in combination with the known technique of reducing display brightness to reduce power consumption. That is, while the scaled display is performed, the power consumption of the display device 304 is further reduced while the brightness of the area of the display device 304 for presenting the scaled display can be reduce.
Please refer to the description in the part of
In this embodiment, when an instruction to scale the display is triggered, in response to the instruction, the GPU may output pixel data for an entire area of the screen, wherein the pixel data for the portion of the screen to be activated presents the scaled-down display and the pixel data for the portion of the screen to be deactivated is black. By the GPU driving back to the portion of the screen to be deactivated, the OLED screen will automatically deactivate the backlight for that portion of the screen, thus providing power saving.
Referring back to the
As shown in
It should be appreciated that the tool options (or plug-ins) 606, 608, 610 are only exemplary. The smart phone 600 may comprise only one of the tool options and also more tool options, and the tool options (or plug-ins) 606, 608, 610 may be configured on the pull-down menu, popup-menu, settings or shortcut options of the smart phone 600.
It should be further appreciated that although in this embodiment, the scalable display is explained in a top left-justified, centered, and bottom-justified manner, the present disclosure is not limited thereto, for example, the scalable display may also be configured in a top right-justified, lower left-justified, lower right-justified, top justified manners. In addition, the trigger option of the scalable display is not limited to the function keys Fn+Fx of the laptop and the tool options (or plug-ins) of the smart phone either, and may also be other entity keys or virtual options of the laptop or the smart phone. For example, the power switch of a smart phone may be configured to enable the smart phone enters a scalable display mode or a lower power consumption mode that includes operating the smart phone with a scaled down display when it is longpressed for a set time. Take another example, the specific operation (e.g. sliding operation) in the specific area of a smart phone or laptop may trigger an instruction to enable the smart phone or the laptop to enter the scalable display mode or the lower power consumption mode that includes operating the smart phone with a scaled down display.
