The specific embodiment is as follows:
fig. 1 shows a schematic structural diagram of a mobile terminal provided in an embodiment of the present application, where in the embodiment, the mobile terminal includes any one of a mobile phone, a notebook computer, and a tablet computer. For convenience of explanation, only the portions related to the present embodiment are shown:
the mobile terminal 1 comprises a display screen module 11, a solar circuit module 12, a solar processing module 13 and an external power supply 14;
the panel of the display module 11 may be a liquid crystal panel.
The solar circuit module 12 and the solar processing module 13 are both configured inside the display screen module 11;
the solar circuit module 12 is used for collecting solar energy, converting the collected solar energy into electric energy and then sending the electric energy to the solar processing module 13 for processing;
the solar energy processing module 13 is configured to process the received electric energy, and supply power to the display screen module 11 by using the processed electric energy;
the external power supply 14 is used for supplying power to the display screen module 11.
In this embodiment, the external power source 14 refers to a power source outside the display module 11. Optionally, the external power supply 14 may supply power to other modules inside the mobile terminal, such as a motherboard, a chip, and the like of the mobile terminal, besides the display screen module 11. The external power source 14 has a fixed maximum charge capacity, and assuming that the maximum charge capacity of the external power source 14 is X, the external power source 14 can be recharged with a new charge after the current charge of the external power source 14 is less than X.
In this embodiment, the solar Circuit module 12 is used as an input end of the electrical energy of the solar processing module 13, the solar processing module 13 processes the electrical energy to obtain a processed voltage and current signal, and then outputs the processed voltage and current signal to the cathode and the anode of the display screen module 11 connected to the solar processing module 13, for example, when the display screen module 11 includes a liquid crystal panel, the solar processing module 13 correspondingly provides the voltage and current signal to a VSN and a VSP inside an Integrated Circuit (IC). The VSN and VSP are positive and negative voltages in a power supply for driving the liquid crystal panel, and the VSN and VSP are a pair and jointly constitute a liquid crystal driving power supply.
It should be noted that, in this embodiment, both the external power source 14 and the solar processing module 13 may supply power to the display screen module 11, and in a specific power supply process, a scheme that the external power source 14 and the solar processing module 13 supply power to the display screen module 11 in turn may be adopted, or a scheme that the external power source 14 and the solar processing module 13 supply power to the display screen module 11 at the same time may be adopted.
In the embodiment of the present application, the mobile terminal includes a display screen module 11, a solar circuit module 12, a solar processing module 13, and an external power supply 14, and the solar circuit module 12 and the solar processing module 13 are both configured inside the display screen module 11. Solar energy circuit module 12 sends after converting the solar energy of gathering into the electric energy to solar energy processing module 13 handles, and by solar energy processing module 13 adopts the electric energy after handling do display screen module 11 supplies power, in addition, external power source 14 is used for doing display screen module 11 supplies power. Since the display screen module 11 is powered by the solar processing module 13 and the external power supply 14, the demand of the display screen module 11 for supplying electric power can be satisfied. In addition, since the electric energy of the solar processing module 13 is converted from solar energy, the electric quantity demand of the display screen module 11 on the external power supply 14 can be reduced, so that the number of charging and discharging times of the external power supply 14 in the same time period can be reduced, and the service life of the external power supply 14 can be prolonged.
Optionally, the solar processing module 13 is a direct current to direct current (DC-DC) module, and at this time, the solar processing module 13 is specifically configured to:
and converting the voltage value corresponding to the received electric energy into a specified voltage value.
In this embodiment, when the display screen module 11 is driven by a dc voltage, it is necessary to ensure that the voltage input to the display screen module 11 is the dc voltage, and to avoid that the service life of the display screen module 11 is lost due to the input of different voltage values, it is necessary to ensure that the voltage value input to the display screen module 11 is within a certain range, and preferably, the voltage value input to the display screen module 11 is a specified voltage value.
Optionally, the solar circuit module 12 is specifically configured to:
the method comprises the steps of collecting solar energy, judging whether the intensity of the solar energy is greater than or equal to a preset intensity threshold value, converting the collected solar energy into electric energy and then sending the electric energy to the solar energy processing module 13 for processing if the intensity of the solar energy is greater than or equal to the preset intensity threshold value.
In this embodiment, if the intensity of the solar energy is determined to be less than the preset intensity threshold, the solar circuit module 12 does not perform the conversion operation. Optionally, in order to save electric power and prevent the solar circuit from being in a working state all the time, if it is determined that the intensity of the solar energy is smaller than a preset intensity threshold, the solar circuit is controlled to keep a sleep detection state before no energy conversion action is executed.
Optionally, prior to collecting solar energy, the solar circuit module 12 is further configured to:
whether sunlight irradiates the display screen module 11 is detected.
Specifically, whether the spectrum of the incident light is the same as the spectrum of the sunlight is determined by detecting the spectrum of the light incident to the display screen module 11, and if so, the incident light is determined to be the sunlight. Optionally, in order to save power and avoid that the solar circuit is always in the working state, the solar circuit is controlled to keep the sleep detection state before the energy conversion action is not executed.
Optionally, in order to be able to convert from solar energy to stable electrical energy, the solar circuit module 12 is specifically configured to:
the method comprises the steps of collecting solar energy within preset time, judging whether the intensity of the solar energy collected within the preset time is greater than or equal to a preset intensity threshold value or not, and if the intensity of the solar energy is greater than or equal to the preset intensity threshold value, converting the collected solar energy into electric energy and then sending the electric energy to the solar energy processing module 13 for processing.
In this embodiment, solar energy is continuously collected, whether the intensity of the collected solar energy is greater than or equal to a preset intensity threshold value or not is judged, and if the intensity of the collected solar energy is greater than or equal to the preset intensity threshold value and the intensity of the collected solar energy is greater than or equal to the preset intensity threshold value within a preset time, the currently collected solar energy is converted into electric energy. Because if the solar energy intensity collected within the preset time is greater than or equal to the preset intensity threshold value, the probability of continuously converting the electric energy is higher, the collected solar energy is converted into the electric energy, and the stability of the output electric energy can be ensured.
Optionally, since the electric energy converted by the solar circuit module 12 is to be input to the display screen module 11, in order to avoid useless conversion operation, the mobile terminal further includes a Central Processing Unit (CPU);
the CPU is configured to determine whether the display screen module 11 is in a working state, and notify the solar circuit module 12 to collect solar energy if the display screen module 11 is in the working state.
Whether the display screen module 11 is in the working state can be judged in the following way: the method comprises the steps of obtaining an attribute value of a screen of a current display screen module 11, comparing the obtained attribute value with a pre-stored bright screen attribute value, judging that the screen of the display screen module 11 is in a bright screen state if the obtained attribute value is the same as the pre-stored bright screen attribute value, comparing the obtained attribute value with a pre-stored black screen attribute value, and judging that the screen of the display screen module 11 is in a black screen state if the obtained attribute value is the same as the pre-stored black screen attribute value. In this embodiment, the display module 11 whose screen is in a bright state is determined to be in a working state. If the screen of the display screen module 11 is in a black screen state, the CPU determines whether the background of the mobile terminal has running applications, and if so, determines that the display screen module 11 is in a working state. Further, since the power consumption of the display module 11 is related to the content that needs to be displayed, for example, the power consumption for displaying the content with rich colors is greater than the power consumption for displaying the content with single color, the solar circuit module 12 can be notified to collect solar energy only after it is estimated that the display module 11 will need a large amount of electric energy. Specifically, if it is determined that there is an application running in the background of the mobile terminal, it is continuously determined whether the application running in the background is an application related to image display, for example, an application playing a video, an application displaying an image, an instant messaging application (e.g., QQ, wechat), and the like, and if the application running in the background is an application related to image display, the solar circuit module 12 is notified to collect solar energy, otherwise, the solar circuit module 12 is not notified to collect solar energy.
Optionally, in case that the solar circuit module 12 has a sunlight detecting function and the CPU also has a solar energy collecting function: the solar circuit module 12 detects whether sunlight irradiates the display screen module 11, if not, the CPU does not execute the step of judging whether the display screen module 11 is in a working state; if the solar circuit module 12 detects that the sunlight irradiates the display screen module 11, the CPU executes a step of determining whether the display screen module 11 is in a working state.
In this embodiment, the solar circuit module 12 collects solar energy only when 2 conditions are satisfied, and therefore, the solar circuit module 12 can be prevented from executing an invalid collecting action.
