An electronic device according to an embodiment of the present application is described below with reference to fig. 1 to 3.
In some embodiments of the present application, an electronic device is provided, where fig. 1 shows one of the schematic structural diagrams of a driving circuit according to an embodiment of the present application, fig. 2 shows the second schematic structural diagram of the driving circuit according to an embodiment of the present application, and fig. 3 shows a schematic structural diagram of an electronic device according to an embodiment of the present application, as shown in fig. 1, fig. 2, and fig. 3, an electronic device 200 includes a first display panel 202, a second display panel 204, and a driving circuit 100, a driving voltage of the second display panel 204 is lower than a driving voltage of the first display panel 202, and the driving circuit 100 includes:
the driving control module 102, wherein the driving control module 102 is electrically connected to the first display panel 202;
the voltage reduction module 104, the driving control module 102 is electrically connected with the second display panel 204 through the voltage reduction module 104;
when the first display panel 202 is in a working state, the voltage reduction module 104 is in a bypass mode, and the driving control module 102 supplies power to the first display panel 202; when the second display panel 204 is in a working state, the voltage-reducing module 104 is in a voltage-reducing mode, and the driving control module 102 supplies power to the second display panel 204 through the voltage-reducing module 104.
In the embodiment of the present application, the electronic device 200 may specifically be an electronic device 200 such as a mobile phone, a tablet computer, a palmtop game machine, and the like, where the electronic device 200 includes a first display panel 202 and a second display panel 204, where the first display panel 202 and the second display panel 204 correspond to a main screen and a sub-screen, respectively.
The "secondary screen" is mainly used for displaying contents such as time, missed calls, unread messages or other beautified wallpaper patterns when the primary screen is turned off, and generally, the display area or the display resolution of the secondary screen is smaller than that of the primary screen, so that the power supply voltage value required by the second display panel 204 of the secondary screen is generally smaller than that required by the first display panel 202 of the primary screen.
Based on this, in the present application, the first display panel 202 and the second display panel 204 multiplex the same driving control module 102, and taking the first display panel 202 and the second display panel 204 as an Active Matrix Organic Light-Emitting Diode (AMOLED) panel as an example, the driving control module 102 can be denoted as an AMOLED Driver.

Here, when the main screen of the electronic device 200 is turned on, the user cannot see and does not need to obtain information through the sub-screen, and thus the sub-screen is turned off at this time. When the main screen is extinguished, the auxiliary screen can be lightened, namely the main screen and the auxiliary screen cannot work simultaneously.
Therefore, when the main screen works, the driving control module 102 supplies power to the first display panel 202, at this time, the voltage reduction module 104 works in a Bypass (Bypass) mode, and in the Bypass mode, the influence of the voltage reduction module 104 on the power supply voltage value is very small and can be ignored, and at this time, the voltage reduction module 104 is equivalent to directly supplying power to the first display panel 202 of the main screen.
When the main screen is turned off and the sub-screen starts to operate, the driving voltage required for operating the second display panel 204 is lower than that of the first display panel 202, so that the Buck module 104 operates in a Buck mode when the second display panel 204 of the sub-screen operates. In the voltage drop mode, the voltage drop module 104 reduces the voltage output by the driving control module, specifically, reduces the working voltage of the second display module to the secondary screen, thereby meeting the requirement of the secondary screen.
