Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
An embodiment of the present invention provides a display method, as shown in fig. 1, the display method includes:
step 101, detecting whether the residual electric quantity of the mobile terminal is smaller than a preset electric quantity threshold value.
And 102, when the residual electric quantity is smaller than a preset electric quantity threshold value, carrying out equal-scale reduction on a current display picture of the mobile terminal to obtain a reduced picture.
And 103, locally displaying the reduced picture on the screen.
In summary, according to the display method provided in the embodiment of the present invention, by the method, when the remaining power is less than the preset power threshold, the mobile terminal can reduce the current display screen of the mobile terminal in an equal proportion, and then locally display the reduced screen on the screen.
An embodiment of the present invention provides another display method, as shown in fig. 2-1, the display method includes:
step 201, detecting whether the residual electric quantity of the mobile terminal is smaller than a preset electric quantity threshold value.
The method can be applied to any electronic equipment with a picture display function, such as a mobile phone, a tablet computer, a laptop computer and the like. Taking a mobile phone as an example, at present, the screen size of the mobile phone is getting larger, the screen size of the mobile phone is changed from 3.5 inches to 4 inches, 5 inches, 5.5 inches or even larger, and the power consumption of the mobile phone is getting larger. When the residual electric quantity of the mobile phone reaches a preset power-off threshold value, the mobile phone in the full-screen display state can be automatically powered off. For example, the preset power-off threshold may be 5% of the total power of the mobile terminal.
By the display method provided by the embodiment of the invention, the mobile terminal can detect whether the residual electric quantity of the mobile terminal is smaller than the preset electric quantity threshold value or not, and when the residual electric quantity is smaller than the preset electric quantity threshold value, the mobile terminal enters a screen-shrinking display mode, namely, the mobile terminal shrinks the current display picture in equal proportion. The preset electric quantity threshold value can be an electric quantity value when the mobile terminal enters a low-electric-quantity mode, and the preset electric quantity threshold value is larger than a preset shutdown threshold value when the mobile terminal is automatically shut down. For example, when the preset power-off threshold is 5% of the total power of the mobile terminal, the preset power threshold may be 15% of the total power of the mobile terminal. In the embodiment of the present invention, if the total power of the mobile terminal is 1, the preset power-off threshold may be represented by 5%, and the preset power threshold may be represented by 15%.
Step 202, when the remaining power is smaller than the preset power threshold, performing equal-scale reduction on the current display picture of the mobile terminal to obtain a reduced picture.
When the mobile terminal detects that the residual electric quantity of the mobile terminal is smaller than the preset electric quantity threshold value, namely the mobile terminal starts to enter a low electric quantity mode, the mobile terminal can reduce the current display picture of the mobile terminal in an equal proportion. Assuming that the preset power threshold is 15% and the remaining power of the mobile terminal is 12% (less than 15%), the mobile terminal may reduce the current display of the mobile terminal in an equal scale, so as to reduce the display area of the display. Therefore, the degree of the low residual capacity of the battery of the mobile terminal at the current moment can be displayed to the user more intuitively, and the user can know how long the mobile terminal can be used before the automatic shutdown more intuitively. Meanwhile, when the remaining power is smaller and smaller, the display area of the display picture is smaller and smaller, and the mobile terminal is automatically powered off until the remaining power is lower than a preset power-off threshold, so that the method is more power-saving in the low power mode, and the service time of the mobile terminal in the low power mode is prolonged.
Optionally, as shown in fig. 2-2, the scaling down the current display screen of the mobile terminal may include:
step 2021, determining a display area of the display screen according to the remaining power, the preset power threshold and the area of the screen.
Optionally, step 2021 may include:
and calculating the display area of the display picture according to the residual electric quantity, the preset electric quantity threshold value and the area of the screen and the first area calculation formula.
The first area calculation formula is:
Figure BDA0001068556430000061
wherein S is1To display area, S0Is the area of the screen, p1For remaining capacity, p0Is a preset electric quantity threshold value.
Illustratively, area S of the screen0Is 81cm2(square centimeter), residual capacity p1Is 12%, a preset electric quantity threshold value p015%, the display area of the display screen can be obtained according to the first area calculation formula
Figure BDA0001068556430000062
It should be noted that, if the remaining power of the mobile terminal is too low, the display area of the display screen may be very small according to the first area calculation formula, so that the display screen displayed on the screen by the mobile terminal according to the display area is relatively small, and the viewing experience of the user is directly affected. So, in order to avoid that the display screen displayed on the screen by the mobile terminal is too small, optionally, step 2021 may include:
and calculating the display area of the display picture according to the residual electric quantity, the preset electric quantity threshold value and the area of the screen and a second area calculation formula.
The second area calculation formula may be:
Figure BDA0001068556430000063
wherein S is1Is a display area, 0 is more than α and less than or equal to 1, S0Is the area of the screen, p1For remaining capacity, p0Is a preset electric quantity threshold value.
For example, α may be equal to
Figure BDA0001068556430000064
That is, the second area calculation formula may be:
Figure BDA0001068556430000065
wherein S is1To display area, S0Is the area of the screen, p1For remaining capacity, p0Is a preset electric quantity threshold value.
For example, α may be equal to
Figure BDA0001068556430000066
That is, the second area calculation formula may also be:
Figure BDA0001068556430000067
wherein S is1To display area, S0Is the area of the screen, p1For remaining capacity, p0Is a preset electric quantity threshold value.
Illustratively, area S of the screen0Is 81cm2Residual electric quantity p1Is 12%, a preset electric quantity threshold value p0Is 15%, then when the second area calculation formula is
Figure BDA0001068556430000068
Then, according to the second area calculation formula, the display area of the display picture can be obtained
Figure BDA0001068556430000069
Therefore, the display area of the display picture obtained by calculation according to the second area calculation formula is larger than that of the display picture obtained by calculation according to the first area calculation formula, and the watching experience of a user is improved.
It should be noted that S in the two second area calculation formulas0The coefficient of (b) can be determined according to the requirement, for example, the second area calculation formula can also be:
Figure BDA0001068556430000071
(S in the formula1To display area, S0Is the area of the screen, p1For remaining capacity, p0A preset charge threshold), which is not limited in the embodiment of the present invention.
Step 2022, the display screen is scaled down according to the display area.
The display screen is reduced in equal proportion according to the display area of the display screen calculated in step 2021. With the area S of the screen in step 20210Is 81cm2And the display area of the display picture obtained by calculation is 64.8cm2For example, the display area of the reduced screen is 80% of the original display area. Here, the scaling down means that the ratio of the length and width of the display screen remains unchanged.
With the area S of the screen in step 20210Is 81cm2And the display area of the display picture obtained by calculation is 72.9cm2For example, the display area of the reduced screen is 90% of the display area of the original screen.
And step 203, displaying the reduced picture on the screen partially.
And after obtaining the reduced picture, the mobile terminal locally displays the reduced picture on the screen. When the remaining power is smaller and smaller, the display area of the display picture is smaller and smaller, and when the remaining power is lower than a preset shutdown threshold, the mobile terminal is automatically shut down. Fig. 2-3 show schematic views before a display is reduced, and fig. 2-4 show schematic views after the display shown in fig. 2-3 is reduced. Because the display picture is reduced, the user can know the residual electric quantity of the mobile terminal at the current moment more intuitively, and meanwhile, because the display picture is small, the effect of saving electricity is achieved, and the service time of the mobile terminal in the low-electricity mode is prolonged.
And step 204, controlling the area on the screen, which is not displayed with the reduced picture, to be in a black screen state.
Further, in order to reduce the consumption of the remaining power of the mobile terminal, the mobile terminal may control an area of the screen where the reduced screen is not displayed to be in a black screen state, as shown in fig. 2 to 4, so that the use time of the mobile terminal in the low power mode is prolonged.
Step 205, receiving a moving instruction for moving the reduced screen to the target area of the screen.
Alternatively, when the user wants to change the display position of the reduced screen on the screen, the user may touch the screen with a stylus or a finger to generate the movement instruction.
And step 206, moving the reduced picture to a target area of the screen according to the moving instruction.
After receiving a moving instruction triggered by a user, the mobile terminal can move the reduced picture to a target area of a screen, so that the user requirements are met, and the user experience is improved.
It should be noted that the order of the steps of the display method provided in the embodiment of the present invention may be appropriately adjusted, and the steps may also be increased or decreased according to the situation. Any method that can be easily conceived by those skilled in the art within the technical scope of the present disclosure is covered by the protection scope of the present disclosure, and thus, the detailed description thereof is omitted.
