Fig. 8 is a detailed flowchart of a control method of an electronic terminal with a display 303 according to a fourth embodiment of the present invention, where the control method of the electronic terminal includes:

s801, detecting whether the electronic terminal meets an energy acquisition condition: the residual quantity of the battery is smaller than a preset electric quantity threshold value and the target application is running.

In the embodiment of the invention, the electronic terminal is a mobile phone, the energy collection condition is that the battery residual quantity of the mobile phone is smaller than a preset electric quantity threshold value, for example, the battery residual quantity of the mobile phone is smaller than 10% of the preset total battery quantity, and the mobile phone is running a preset target application, for example, a game application with large power consumption.

S802, the control unit of the electronic terminal controls the first solar panel and the second solar panel to collect light energy, the light energy is converted into electric energy, the electric energy is processed, the battery of the electronic terminal is charged, and meanwhile the electric quantity of the battery is monitored.

When the mobile phone detects that the game application is running and the battery remaining amount of the mobile phone is less than 10% of the total amount of the battery, the energy acquisition rule preset in the memory of the control unit in the mobile phone controls the transparent first solar panel 132 in the display screen 303 to acquire the light source emitted by the self-luminous light source panel 3031 in the display screen 303 and the light source of the external environment of the mobile phone, the first solar panel 132 converts the acquired light sources at the two positions into electric energy to charge the battery of the electronic terminal after processing the electric energy, and the control unit in the mobile phone also controls the second solar panel 170 to convert the electric energy acquired by the light source of the external environment of the mobile phone into electric energy to charge the battery of the. While charging, the control unit of the mobile phone also monitors the battery level, and when it is confirmed that the battery level is fully charged, S803 is executed.

And S803, the first solar panel 132 and the second solar panel 170 are forbidden to supply power to the electronic terminal by converting the light energy into the electric energy.

The following ways of prohibiting the solar panel from converting the light energy into the electric energy to supply power to the electronic terminal are available:

The control method of the electronic terminal with the display screen 303 provided by this embodiment is applied to the case that the battery remaining capacity of the mobile phone is smaller than the preset battery threshold value in the daytime and the mobile phone is running the preset target application, and charges the battery of the electronic terminal after the control unit of the mobile phone processes the electric energy converted from the light energy collected by the first solar panel 132 and the second solar panel 170 in the display screen 303 of the mobile phone, so that the inconvenience of charging the electronic device due to the fact that the user must rely on an external power supply is avoided, and the user experience is improved.
