It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. 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 invention.
The terms "first", "second", and the like in the present invention are used for distinguishing different objects, not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The mobile terminal provided by the embodiment of the invention can be a mobile phone, a tablet personal computer, an intelligent wearable device and the like.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating an embodiment of a method for reducing a temperature rise of a mobile terminal, the method including:
s11: the temperature of the mobile terminal is detected.
Optionally, in an embodiment, the temperature of the mobile terminal may be detected in real time in a power-on state of the mobile terminal; in another embodiment, the temperature of the mobile terminal can be detected in real time in a state that a screen of the mobile terminal is lighted.
Specifically, the temperature of the mobile terminal may be detected specifically, the temperature of a display screen of the mobile terminal may also be detected, the temperature of a battery or other components may also be detected, and in addition, the temperatures of multiple places of the mobile terminal may also be detected to obtain an average value through calculation. Taking the display screen as an example, one or more temperature sensors may be disposed inside or at other positions of the display screen to detect the temperature of the display screen. Alternatively, the temperature sensor may be a thermistor.
S12: and when the temperature of the mobile terminal is greater than a preset value, judging whether an effective display picture in a current operation interface displayed by a display screen of the mobile terminal is displayed in a full screen mode.
The preset value may be a default value in a factory setting of the mobile terminal, or may be determined according to a setting of a user, which is not limited herein.
The current operation interface of the display screen refers to all displayed pictures in the display screen, and the effective display pictures are different according to different application scenes. For example, when a video is played, the effective display screen is a video playing interface; when chatting software is used for chatting, the effective display picture is a message bar and an input method bar; when music is played, the effective display screen is an audio adjusting button (such as a button for playing, pausing, next music and the like).
Specifically, taking video playing on a mobile phone as an example, when a video is played on a horizontal screen (i.e., full screen), it is equivalent to that an effective display picture is displayed in full screen; when the video is played on the vertical screen, the video is often played in a part of display areas of the mobile phone, and other display areas can display characters related to the video or other contents irrelevant to the video content, which belong to non-effective display pictures.
In step S12, if the determination result is yes, step S13 is executed, and if the determination result is no, step S14 is executed.
S13: and reducing and displaying the effective display picture, and setting the rest area of the display screen as a black screen.
As shown in fig. 2, in an embodiment, taking the mobile phone 20 as an example, in the display screen 21, the operation interface 211 is a video playing interface, and the operation interface 211 is an effective display screen. It is understood that the video playing picture played in full screen is called horizontal screen playing.
As shown in fig. 3, in the present embodiment, the horizontal and vertical screens of the display screen are not switched, but the original display screen is simply reduced in a set ratio. While the remaining area 212 is set to a black screen.
Optionally, in this embodiment, the scale of the reduced screen may be set arbitrarily, and in addition, a drag button may be further set at the edge of the displayed screen, so that when a touch operation of a user is received, the size of the displayed screen may be adjusted at will.
S14: and setting the rest area of the display screen except the effective display picture as a black screen.
As shown in fig. 4, in another embodiment, taking the mobile phone 30 as an example, in the display screen 31, a part of the operation interface is a video playing interface, and in this embodiment, the video playing screen is in a vertical screen playing mode. It will be appreciated that in the portrait play mode, the play screen 311 occupies only a portion of the display screen 31, with the remaining area typically displaying text or video-related introductions, comments, and the like. In the present embodiment, the video play screen 311 is retained, and the remaining area 312 is set as a black screen.
Alternatively, in the embodiments of S13 and S14, the effective display screen may be a horizontal full-screen display screen as shown in fig. 2, or may be switched to a vertical display screen as shown in fig. 4, and then the remaining area is set to be displayed as a black screen.
Optionally, in the above embodiment, the effective display screen may be switched in real time according to the placement state of the mobile phone detected by the gravity sensor in the mobile phone. For example, in the display state shown in fig. 3, if it is detected that the mobile phone is switched to the vertically-placed state, the display screen is switched to the display state shown in fig. 4; in the display state shown in fig. 4, if it is detected that the mobile phone is switched to the landscape orientation state, the display screen is switched to the display state shown in fig. 3.
Optionally, in another embodiment, when the mobile terminal receives a touch operation of a user, or when the temperature of the mobile terminal is less than a preset value, the display screen is restored to the initial state.
Specifically, although the reduction of the effective display screen or the setting of the remaining area as a black screen reduces the power consumption of the mobile terminal to some extent, the user experience may be affected. Therefore, in an embodiment, when the user needs to restore the display screen, the user may touch the display screen or press a home key on the mobile terminal to restore the display screen. In a specific example, in order to avoid the misoperation, the display screen can be restored by touching the black screen area. In this embodiment, when the remaining area is set as a black screen, the touch function of the touch screen in the remaining area is not turned off, so that the touch operation can still be performed in the black screen area. Of course, in other embodiments, the corresponding touch function may also be turned off, and then, when the display screen is restored, the effective display area may be touched or the home key may be clicked.
Specifically, in another embodiment, whether to restore the display screen may also be determined by the temperature acquired by the temperature sensor in real time. When the temperature is greater than the preset value, steps such as S13 and S14 are performed, by which the temperature rise of the terminal can be reduced, and in addition, the temperature rise of the terminal can be reduced by other means, and it is known that when the temperature of the terminal is less than the preset value, the display screen is restored to the initial state.
In another embodiment of the method for reducing the temperature rise of the mobile terminal provided by the invention, the display screen can be divided into at least two areas in advance. Then, in step S11, the temperatures of at least two regions may be detected respectively.
Therefore, when the effective screen is displayed, the effective screen can be displayed in any one of the at least two divided areas and then switched.
In one embodiment, the effective display frames can be alternately displayed in different areas of the display screen according to a set time sequence. In another embodiment, the effective display frame may be alternately displayed in at least two regions with a temperature less than a preset value according to a set time sequence.
Of course, in other embodiments, the switching may be performed not according to a set timing but according to the temperature of a different region.
As shown in fig. 5, in the landscape display mode, the display screen may be divided into four areas in advance, and the effective display screen is displayed in one of the areas, and then the display areas are sequentially replaced in the order of the arrows shown in the figure.
As shown in fig. 6, in the vertical screen display mode, the display screen may be divided into two areas in advance, and the effective display screen is displayed in one of the two areas and then alternately displayed in the two areas according to the arrow shown in the figure.
Optionally, continuing to use fig. 6 as an example, in an embodiment, now the first area displays the effective picture, when the temperature of the second area decreases below the preset value, the effective picture is displayed in the second area, and when the temperature of the first area decreases below the preset value, the first area is switched to display the effective pictures, and the steps are sequentially alternated.
The method for reducing the temperature rise of the mobile terminal provided by the embodiment of the invention comprises the following steps: detecting the temperature of the mobile terminal; when the temperature of the mobile terminal is greater than a preset value, judging whether an effective display picture in a current operation interface displayed by a display screen of the mobile terminal is displayed in a full screen mode; if so, reducing and displaying the effective display picture, and setting the rest area of the display screen as a black screen; and if not, setting the rest area except the effective display picture in the display screen as a black screen. Through the mode, the display can be performed only by using the partial area of the display screen at the same time, so that the power consumption of the display screen is effectively reduced, and the temperature rise of the mobile terminal is reduced.
The present invention also provides a computer-readable storage medium on which a schematic structural diagram of an embodiment of a computer program is stored, the computer-readable storage medium being used for storing the computer program, and the computer program being executed by a processor to implement the method provided in the above embodiment.
