To solve the above problems, the present disclosure provides an electronic device, which is described in detail below with reference to the accompanying drawings:

FIG. 2 is a block diagram illustrating an electronic device according to an exemplary embodiment of the present disclosure. Referring to fig. 2, the electronic device includes: the display device comprises a control module 210, a driving module 220 and a plurality of display modules 230, wherein the driving module 220 comprises a power supply port 221, a first input port 222 and a second input port 223; the input ports of the display modules 230 are connected to the power port 221, the output ports of the display modules 230 are connected to the first input port 222 of the driving module 220, and the output port of the control module 210 is connected to the second input port 223 of the driving module 220.

The control module 210 may be a Central Processing Unit (CPU). The driving module 220 may be a driving chip. The display module 230 may be a display screen, such as an OLED display screen, an LED display screen, or the like.

In application, the control module 210 determines a target display module 230 to be driven, and controls the driving module 220 to drive the target display module.

After determining the target display module 230 to be driven, the control module 210 may send a corresponding signal to the driving module 220, where the signal indicates the target display module 230, and the driving module 220 identifies the signal, determines that the target display module 230 needs to be driven, and drives the target display module 230 according to the signal. The different display modules 230 may be indicated by the waveform, frequency, etc. characteristics of the signal.

The driving module 220 may drive only one display module 230 at a time, and may drive several display modules 230 at the same time when the driving capability is strong.

In the structure, the electronic equipment drives the display modules by using one driving module, and compared with the driving of one display module by using one driving module, the driving module has the advantages that the using number of the driving modules is reduced, the occupied area of the driving module on a printed circuit board is reduced, other devices can be favorably installed on the printed circuit board, and meanwhile, the manufacturing cost of the electronic equipment is reduced.

In some embodiments, the control module 210 in fig. 2 may further include an obtaining circuit and a processing circuit, where the obtaining circuit is connected to the processing circuit and an output port of the control module 210, and is configured to obtain the usage information of the electronic device and send the usage information to the processing circuit; the processing circuit is configured to determine a target display module to be driven according to the usage information of the electronic device, send a first signal for driving the target display module to the driving module 220 through an output port of the control module 210, and trigger the driving module 220 to drive the target display module.

The control module 210 determines the target display module 230 in various ways, for example, the control module 210 determines the target display module 230 to be driven according to the folded states of the plurality of display modules 230. In one example, the electronic device includes two display screens, and it is preset that when the two display screens are folded, the display screen to be driven is determined to be the display screen 1, and when the two display screens are unfolded, the display screen to be driven is determined to be the display screen 2.

For another example, the user may input module information of the target display module 230, such as a number of the target display module, to the electronic device, and the control module 210 determines the target display module 230 to be driven according to the module information input by the user. There are various ways in which a user may input module information to an electronic device, such as selecting an on-screen option, pressing a physical key, inputting a voice command, etc.

The signal characteristics, such as the magnitude, waveform, frequency, etc., of the signal are different for different display modules 230. The control module 210 generates a first signal according to the signal characteristic corresponding to the target display module 230.

For example, when the target display screen is the display screen 1, the first signal is a high-level pulse signal; when the target display screen is the display screen 2, the first signal is a pulse signal of a low level. After receiving the first signal, the driving module 220 determines that the target display screen is the display screen 1 by recognizing that the first signal is a high level signal, and determines that the target display screen is the display screen 2 by recognizing that the first signal is a low level signal.

In some embodiments, the driving module 220 in fig. 2 may further include a driving circuit and a control circuit, the control circuit is connected to the driving circuit, the first input port 222 and the second input port 223, and the driving circuit is connected to the power port 221;

The target driving information required by the plurality of display modules 230 may be the same or different, and is determined by factors such as the structure, performance, and usage requirements of each display module. The driving information may include a driving voltage.

Generally, the information value of the initial driving information stored in the driving module 220 is small, and the information value of the target driving information stored in the display module 230 is large. The display module 230 is driven by using the initial driving information, so that the display module 230 can finish displaying in a short time, and the display module 230 is driven by using the target driving information stored in the display module 230, so that the display module 230 can display according to the required brightness, and the use requirement of the user is met.

In some embodiments, the number of the power ports of the driving module 220 is multiple, and the power ports connected to the input ports of different display modules 230 are different.

Based on the above structure, the driving module 220 is convenient to control different display modules 230.

In some embodiments, a plurality of driving voltages are required to drive the display module 230 successfully, and the driving module 220 needs to use different lines to output different driving voltages to the display module 230.

In application, after determining the target display module to be driven, the control module 210 sends a second signal to the switch component 240 through the second output port 212, where the second signal is used to trigger the switch component 240 to connect the target display module 230 to be driven with the driving module 220, so that the driving module 220 drives the target display module 230.

Based on the setting of the switch component 240, the electronic device turns on the target display module 230 and the driving module 220 only when the target display module 230 needs to be driven, so that the driving module 220 can determine which display module 230 transmits the received target driving information.
