Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method.
The first embodiment,
An embodiment of the present invention provides a control method, applied to a mobile terminal, as shown in fig. 3, including:
step 301: the mobile terminal is in a first display state, wherein the first display state represents a state that the mobile terminal at least adopts a first display unit to display information;
step 302: acquiring the residual electric quantity of the mobile terminal, and judging whether the mobile terminal meets a first preset condition according to the residual electric quantity of the mobile terminal, wherein the first preset condition represents that the display power consumption of the mobile terminal needs to be reduced;
step 303: if the mobile terminal is determined to meet a first preset condition, controlling the mobile terminal to be switched from a first display state to a second display state, wherein the second display state represents a state of closing the first display unit and displaying information through the second display unit; the second display unit is a display unit with power consumption smaller than that of the first display unit.
In this embodiment, the first display unit and the second display unit may be respectively disposed on the front side and the back side of the mobile terminal, for example, see fig. 4 and 5. In the figure, the first display unit is a display unit generally used by the mobile terminal, and the second display unit may be an ink screen with lower power consumption, or may be a display parameter different from the first display unit, that is, assuming that the first display unit uses the RGB display protocol for displaying, the second display unit may be set to use only black and white for displaying. It should be understood that the embodiment does not limit the specific implementation units of the first display unit and the second display unit, as long as the power consumption of the second display unit can be ensured to be low. For example, fig. 4 is a schematic front view of a dual-screen display mobile phone, and fig. 5 is a schematic back view. The dual-screen display mobile phone comprises a first display screen 40 on the front side and a second display screen 50 on the back side.
The first display screen 40 may be an LCD, LED screen.
The second display screen 50 may be an ink screen, an LCD screen, or an LED screen. In order to facilitate the arrangement of modules such as a camera on the back surface, the size of the second display screen 50 may be smaller than that of the first display screen 40. When the second display screen 50 is an ink screen, the standby time can be prolonged by adopting the second display screen 50 because the energy consumption of the ink screen is low; when the second display screen 50 is an LCD or LED screen, the display parameters of the second display screen 50 may be changed, for example, the second display screen 50 may be adjusted to a black-and-white mode or a mode with lower color, so as to reduce power consumption.
The first display state may be: only starting the first display unit to display information; the first display unit and the second display unit can be both opened and can simultaneously display information according to the control of a user.
The method for acquiring the remaining power of the mobile terminal may be: detecting a power supply unit of the mobile terminal in real time to obtain operation parameters of the power supply unit; and acquiring the residual electric quantity of the mobile terminal by analyzing the operation parameters.
The first preset condition may be set according to actual conditions, for example, the first preset condition may be set as: whether the residual capacity is smaller than a residual capacity threshold value or not is set according to requirements, and the residual capacity threshold value can be set to be 10% or 5%; alternatively, whether the operation time length of the mobile terminal supported by the remaining power may satisfy the preset time length may be set, for example, the preset time length may be 1 hour, or may be 2 hours.
In this embodiment, the second display state may be a state in which only the second display unit is turned on for displaying; the first display unit and the second display unit are of the same type and are both LCD screens:
when the first display state is that the first display unit and the second display unit are turned on and the first display unit and the second display unit both adopt the same display parameters, the second display state may be that only the second display unit is turned on and the display parameters are not changed;
or, the second display state may be that only the second display unit is turned on, and the display parameters are changed, assuming that the original display parameters may be RGB, and the modified display unit may be the display parameters for controlling to display only black and white colors.
The first display unit and the second display unit are different in type, for example, the first display unit is an LCD display screen, and the second display unit is an ink screen:
when the first display state is to turn on the first display unit and the second display unit, the second display state may be to turn on only the second display unit;
when the first display state is to turn on only the first display unit, the second display state may be to turn on only the second display unit.
The embodiment can be used for realizing multiple functions by setting the front screen and the rear screen on the mobile phone, so that the performance of the mobile phone is enhanced, and the user experience is improved. Wherein, different screens are selected for display according to different application programs. The front screen (main screen) can be used for normally displaying various functions such as videos, games and the like; the rear screen (auxiliary screen) can be used for displaying electronic books, character information and the like with low power consumption; thereby extending the standby time.
The flow of the above scheme can be seen in fig. 6, which includes:
in step 601, a power threshold is calculated according to the usage.
In step 602, when the current power amount is lower than the power amount threshold, a power saving mode is prompted to enter.
In step 603, the main screen is closed and the sub-screen is used for displaying.
In step 604, the corresponding power supply parameters are adjusted according to the secondary screen. Wherein, the adjusting the power supply parameter may include: voltage, current, etc.
Therefore, in the above scheme, for the mobile terminal with two display units, by detecting the current use condition of the mobile terminal, that is, the remaining power, when the remaining power meets the first preset condition, the second display unit with lower power consumption is controlled to be started for displaying. Thereby prolonging the service time and improving the user experience.
Example II,
An embodiment of the present invention provides a control method, applied to a mobile terminal, as shown in fig. 3, including:
step 301: the mobile terminal is in a first display state, wherein the first display state represents a state that the mobile terminal at least adopts a first display unit to display information;
step 302: acquiring the residual electric quantity of the mobile terminal, and judging whether the mobile terminal meets a first preset condition according to the residual electric quantity of the mobile terminal, wherein the first preset condition represents that the display power consumption of the mobile terminal needs to be reduced;
step 303: if the mobile terminal is determined to meet a first preset condition, controlling the mobile terminal to be switched from a first display state to a second display state, wherein the second display state represents a state of closing the first display unit and displaying information through the second display unit; the second display unit is a display unit with power consumption smaller than that of the first display unit.
In this embodiment, the first display unit and the second display unit may be respectively disposed on the front side and the back side of the mobile terminal, for example, see fig. 4 and 5. In the figure, the first display unit is a display unit generally used by the mobile terminal, and the second display unit may be an ink screen with lower power consumption, or may be a display parameter different from the first display unit, that is, assuming that the first display unit uses the RGB display protocol for displaying, the second display unit may be set to use only black and white for displaying.
The first display state may be: only starting the first display unit to display information; the first display unit and the second display unit can be both opened and can simultaneously display information according to the control of a user.
The method for acquiring the remaining power of the mobile terminal may be: detecting a power supply unit of the mobile terminal in real time to obtain operation parameters of the power supply unit; and acquiring the residual electric quantity of the mobile terminal by analyzing the operation parameters.
The first preset condition may be set according to actual conditions, for example, the first preset condition may be set as: whether the residual capacity is smaller than a residual capacity threshold value or not is set according to requirements, and the residual capacity threshold value can be set to be 10% or 5%; alternatively, whether the operation time length of the mobile terminal supported by the remaining power may satisfy the preset time length may be set, for example, the preset time length may be 1 hour, or may be 2 hours.
Specifically, the method for judging whether the mobile terminal meets a first preset condition according to the residual electric quantity of the mobile terminal includes the following modes:
in a first way,
Determining the residual working time of the mobile terminal according to the residual electric quantity of the mobile terminal;
and judging whether the residual working time of the mobile terminal meets a preset time, and if so, determining that the mobile terminal meets a first preset condition.
The method for determining the remaining duration of the mobile terminal may be: and predicting the remaining duration of the mobile terminal according to the remaining power and the first display state.
Determining the remaining operating time of the mobile terminal, wherein the remaining operating time may be calculated according to the display power consumption of the first display state and the remaining power.
It is understood that, in the process of determining the remaining operating time period in the present embodiment, the power consumption speed of the application currently used by the user may be further considered. For example, when a user currently opens an application with high power consumption, such as a game, the remaining operating time is calculated according to the power consumption speed of the application and the current remaining power.
The second way,
The judging whether the mobile terminal meets a first preset condition according to the residual electric quantity of the mobile terminal comprises the following steps:
acquiring the current moment, and determining the predicted working time between the current moment calculation and the predicted charging moment;
determining the residual working time of the mobile terminal according to the residual electric quantity of the mobile terminal;
and judging whether the residual working time of the mobile terminal is less than the expected working time, and if so, determining that the mobile terminal meets a first preset condition.
It is understood that, in the process of determining the remaining operating time period in the present embodiment, the power consumption speed of the application currently used by the user may be further considered. For example, when a user currently opens an application with high power consumption, such as a game, the remaining operating time is calculated according to the power consumption speed of the application and the current remaining power.
The method for acquiring the charging time may be: and acquiring input information, and acquiring the expected charging time according to the input information.
Specifically, the user may be prompted to input the expected charging time, the input information of the user is obtained, and the expected charging time is determined according to the input information of the user.
The third method,
The judging whether the mobile terminal meets a first preset condition according to the residual electric quantity of the mobile terminal comprises the following steps:
acquiring the current moment, and determining the predicted working time between the current moment calculation and the predicted charging moment;
determining an electric quantity threshold according to the residual electric quantity of the mobile terminal and the estimated working time;
and judging whether the residual electric quantity of the mobile terminal is smaller than the electric quantity threshold value, if so, determining that the mobile terminal meets a first preset condition.
Wherein, the determining the power threshold according to the remaining power of the mobile terminal and the expected operating time specifically may include: and calculating the electric quantity threshold according to the expected use duration, the residual electric quantity and the electric quantity consumption value of the auxiliary screen.
For example, a user charges at 10 pm every day, now at 4 pm, and needs to use for 6 hours, the electric quantity remains 10%, and if the auxiliary screen electric quantity is consumed by 1% every hour, the electric quantity threshold is determined to be 6%. That is, the required power amount for operating the expected operating time by turning on only the second display unit is determined based on the power consumption amount per hour of the second display unit, and the required power amount is used as the power amount threshold. Therefore, as long as the second display unit is started when the electric quantity threshold is reached, the normal operation of the mobile terminal can be ensured until the expected charging time.
In this embodiment, the second display state may be a state in which only the second display unit is turned on for displaying;
in addition, the first display unit and the second display unit are of the same type and are both LCD screens:
when the first display state is that the first display unit and the second display unit are turned on and the first display unit and the second display unit both adopt the same display parameters, the second display state may be that only the second display unit is turned on and the display parameters are not changed;
or, the second display state may be that only the second display unit is turned on, and the display parameters are changed, assuming that the original display parameters may be RGB, and the modified display unit may be the display parameters for controlling to display only black and white colors.
When the types of the first display unit and the second display unit are different, the first display unit is an LCD display screen, and the second display unit is an ink screen:
when the first display state is to turn on the first display unit and the second display unit, the second display state may be to turn on only the second display unit;
