When the current state is the unfolding state, the first display module and the second display module are both in the using state, and then the target display module is determined to be the first display module and the second display module.

In one possible implementation, the current state is a folded state, and when the foldable device is opened, the foldable device determines the currently illuminated display module as the target display module in the use state.

In another possible implementation manner, when the current state is a folded state and the foldable device is in a standby state, the foldable device may determine the display module corresponding to the upward lighted display area as a target display module in a use state; or, the foldable device may determine the display module corresponding to the last used display area as the target display module currently in the use state; or the foldable equipment determines the display module corresponding to the display area with high use frequency in the preset time before the current time as the target display module in the use state.

When the current state is a folded state, the first display module or the second display module is in a use state, and when the first display module is in the use state, the target display module is determined to be the first display module; and when the second display module is in a use state, determining that the target display module is the second display module.

In step S402, the foldable device determines a target power supply module for supplying power to the target display module according to the target display module.

In one possible implementation manner, when the target display module is the first display module and the second display module, determining that the target power supply module is the first power supply module and the second power supply module; or, determining the target power supply module as a first power supply module; or, determining that the target power supply module is the second power supply module.

In this implementation, when the target display module is the first display module and the second display module, the first power supply module can supply power to the target display module, the second power supply module can also supply power to the target display module, and the first power supply module and the second power supply module can also supply power to the target display module. In the embodiment of the present disclosure, when the target display module is the first display module and the second display module, the target power supply module is not specifically limited.

In another possible implementation manner, when the target display module is the first display module, the target power supply module is determined to be the first power supply module. And when the target display module is the second display module, determining that the target power supply module is the second power supply module.

In this disclosed embodiment, by the power module that directly links to each other with the target display module assembly for the power supply of target display module assembly, improved the transport efficiency in the electric quantity transmission process, reduced the electric quantity loss in the electric quantity transmission process.

In another possible implementation manner, when the target display module is the first display module, the target power supply module is determined to be the second power supply module. And when the target display module is the second display module, determining that the target power supply module is the first power supply module.

In the embodiment of the disclosure, the power supply module which is not in the same shell with the target display module supplies power to the target display module, so that the electromagnetic interference generated by the target power supply module in the power supply process is reduced.

It should be noted that, in this disclosure, when the foldable device is in the folded state and the target display module is the first display module or the second display module, the target power supply module supplies power to the target display module. When the target display module is in the use state, another display screen that does not use is standby, and other power supply modules in the power supply module can be for the power supply of another display screen, and when only another display screen was standby, power consumption was less, compares in the power consumption of the target display module of use state, and its power consumption can be ignored. Therefore, in the present disclosure, the target power supply module supplies power to the target display module mainly for the target display module in a use state.

In step S403, the foldable device supplies power to the target display module through the target power supply module.

In one possible implementation manner, the target power supply module is a first power supply module, and when the target display module is a first display module, the first power supply module supplies power to the first display module; when the target display module is the first display module and the second display module, the first power supply module supplies power to the first display module and the second display module.

In another possible implementation manner, the target power supply module is a second power supply module, and when the target display module is a second display module, the second power supply module supplies power to the second display module; when the target display module is the first display module and the second display module, the second power supply module supplies power to the first display module and the second display module.

In the embodiment of the present disclosure, the target power supply module is not specifically limited to be the first power supply module or the second power supply module.

In the embodiment of the disclosure, after the foldable device determines the target power supply module, it may be determined whether the target power supply module supplies power to the target display module or other power supply modules supplies power to the target display module according to the current first remaining capacity of the target power supply module.

In a possible implementation manner, after the foldable device determines the target power supply module, the foldable device also determines a current first remaining capacity of the target power supply module; and when the first residual electric quantity is not greater than the first preset electric quantity, supplying power to the target power supply module through other power supply modules in the power supply modules.

In this implementation, the foldable device determines a current first remaining power of the target power supply module, and when the first remaining power is greater than a first preset power, the target power supply module supplies power to the target display module. And when the first residual electric quantity is not greater than the first preset electric quantity, other power supply modules in the power supply modules supply power to the target power supply module.

For example, the first preset power is 10%, and when the target power supply module is the first power supply module, the foldable device determines a current first remaining power of the first power supply module. For example, if the first remaining capacity is 30% and the first remaining capacity is greater than the first preset capacity by 10%, the first power supply module supplies power to the target display module. For example, if the first remaining capacity is 5% and the first remaining capacity is not greater than 5% and the first predetermined capacity is not greater than 10%, the second power supply module supplies power to the first power supply module.

The first preset electric quantity may be a default electric quantity, or may be determined according to an application currently running on the foldable device. The currently running application includes a foreground application and/or a background application. Correspondingly, before or after the foldable device determines the current first remaining power of the target power supply module, the foldable device determines a first preset power according to the currently running application program, and the process may be:

in a first implementation manner, a corresponding relation between an application program and a preset electric quantity is stored in a foldable device; the foldable device obtains a first preset electric quantity corresponding to the currently running application program from the corresponding relation between the application program and the preset electric quantity according to the currently running application program.

In a second implementation manner, the corresponding relation between the application program type and the preset electric quantity is stored in the foldable device; the foldable device determines the type of the application program according to the currently running application program, and obtains a first preset electric quantity corresponding to the currently running application program from the corresponding relation between the type of the application program and the preset electric quantity according to the type of the application program.

It should be noted that there may be one or more currently running applications. When a plurality of currently running applications exist, the preset electric quantities corresponding to the plurality of applications can be determined according to the method, the maximum electric quantity in the preset electric quantities corresponding to the plurality of applications is used as a first preset electric quantity, and the preset electric quantities corresponding to the plurality of applications can also be subjected to weighted summation to obtain the first preset electric quantity.

The point to be described is that when the other power supply modules supply power to the target power supply module, so that the first remaining power of the target power supply module reaches the fifth preset power, the other power supply modules temporarily stop supplying power to the target power supply module, and the target power supply module supplies power to the target display module. And the fifth preset electric quantity is greater than the first preset electric quantity.

For example, if the target power supply module is the first power supply module, the first remaining power is 5%, the first preset power is 10%, and the first remaining power is 5% smaller than the first preset power by 10%, the second power supply module supplies power to the first power supply module. When the second power supply module supplies power to the first power supply module, so that 5% of the first remaining power of the first power supply module reaches a fifth preset power, for example, the fifth preset power is 30%. The second power supply module temporarily stops supplying power to the first power supply module, and the first power supply module supplies power to the target display module.

Another point to be described is that, when other power supply modules supply power to the target power supply module, so that the fourth remaining power of other power supply modules is not greater than the sixth preset power, other power supply modules temporarily stop supplying power to the target power supply module, and the target power supply module supplies power to the target display module.

For example, the target power supply module is a first power supply module, the first remaining capacity is 5%, the first preset capacity is 10%, the fourth remaining capacity is 8%, and the sixth preset capacity is 15%. When the first residual electric quantity of the first power supply module is 5% less than the first preset electric quantity of 10%, the second power supply module supplies power to the first power supply module. When the second power supply module supplies power to the first power supply module, so that 8% of the fourth residual electric quantity of the second power supply module is not more than 15% of the sixth preset electric quantity, the second power supply module temporarily stops supplying power to the first power supply module, and the first power supply module supplies power to the target display module.

The size of the first preset electric quantity can be set and changed as required. In the embodiment of the present disclosure, the magnitude of the first preset electric quantity is not particularly limited. For example, the first preset amount of power is 5%, 8%, or 10%. The size of the first remaining capacity can be set and changed as required. In the embodiment of the present disclosure, the magnitude of the first remaining capacity is not particularly limited. For example, the first remaining capacity is 30%, 40%, or 50%. The fifth preset electric quantity is larger than the first preset electric quantity, and the fifth preset electric quantity can be any value larger than the first preset electric quantity. In the embodiment of the present disclosure, the magnitude of the fifth preset electric quantity is not particularly limited. For example, if the first preset amount of power is 5%, the fifth preset amount of power may be 20%, 30%, or 40%.

The magnitude of the sixth preset electric quantity can be set and changed as required. In the embodiment of the present disclosure, the magnitude of the sixth preset electric quantity is not particularly limited. For example, the magnitude of the sixth preset amount of power is 5%, 10%, or 15%. The fourth remaining capacity is not greater than the sixth preset capacity, that is, the fourth remaining capacity may be less than the sixth preset capacity or equal to the sixth preset capacity. In the embodiment of the present disclosure, the fourth remaining capacity is not particularly limited.

The other point to be described is that the sixth preset electric quantity may be 0, that is, other power supply modules supply power to the target power supply module, and all the electric quantity of the current electric quantity of the power supply module may be used to supply power to the target power supply module, or a part of the electric quantity of the current electric quantity of the power supply module may be used to supply power to the target power supply module. In the embodiments of the present disclosure, this is not particularly limited.

In another possible implementation manner, after the foldable device determines the target power supply module, the foldable device further determines a current first remaining capacity of the target power supply module; and when the first residual electric quantity is not greater than the second preset electric quantity, changing the target power supply module into other power supply modules in the power supply module.

In this implementation, the foldable device determines a current first remaining power of the target power supply module, and when the first remaining power is greater than a second preset power, the target power supply module supplies power to the target display module. And when the first residual electric quantity is not greater than the second preset electric quantity, changing the target power supply module into other power supply modules.

When the first residual electric quantity is larger than the second preset electric quantity, the foldable equipment periodically detects the current first residual electric quantity of the target power supply module in the process of supplying power to the target display module by the target power supply module; and when the first residual electric quantity is not greater than the second preset electric quantity, changing the target power supply module into other power supply modules in the power supply module.

For example, the second preset power is 10%, and when the target power supply module is the first power supply module, the foldable device determines a current first remaining power of the first power supply module. For example, if the first remaining capacity is 30% and the first remaining capacity is greater than the second predetermined capacity by 10%, the first power supply module supplies power to the target display module. For example, if the first remaining capacity is 5% and the first remaining capacity is not greater than 5% and the second predetermined capacity is not greater than 10%, the second power supply module is used as the target power supply module, and the second power supply module supplies power to the target display module.

The size of the second preset electric quantity can be set and changed as required. In the embodiment of the present disclosure, the magnitude of the second preset electric quantity is not particularly limited. For example, the second preset amount of power is 5%, 10%, or 15%.

In step S503, the foldable device determines a target power supply module for supplying power to the target display module according to the second remaining power and the third remaining power.

In this step, when the second remaining capacity is greater than the third remaining capacity, the foldable device determines that the target power supply module is the first power supply module. When the second remaining capacity is not greater than the third remaining capacity, the foldable device determines that the target power supply module is the second power supply module.

For example, when the second remaining capacity is 70% and the third remaining capacity is 50%, and the second remaining capacity is 70% greater than the third remaining capacity by 50%, the foldable device determines that the target display module is powered by the first power supply module. For example, when the second remaining capacity is 40% and the third remaining capacity is 60%, and the second remaining capacity is 40% and less than the third remaining capacity 60%, the foldable device determines that the target display module is powered by the second power supply module.

The size of the second remaining capacity can be set and changed as required. In the embodiment of the present disclosure, the magnitude of the second remaining capacity is not particularly limited. For example, the second remaining capacity is 60%, 70%, or 80%.

The size of the third remaining capacity can be set and changed as required. In the embodiment of the present disclosure, the magnitude of the third remaining capacity is not particularly limited. For example, the third remaining capacity is 50%, 60%, or 70%.
