For example, the main screen may be an LCD or OLED display screen of a terminal device such as a smartphone or a tablet computer; the sub screen may be an electronic ink (Eink) screen. Specifically, the secondary screen can adopt a meta-Tai electronic ink screen, utilizes a bistable display technology of reflective light display, and displays different contents based on the driving combination of black-white ink capsules with positive and negative charges. In some embodiments, the plug-and-play of the secondary screen module can be realized by using a specially designed interface capable of detecting the insertion state, and the display of the primary screen and the secondary screen can be freely switched.

Taking a tablet personal computer as an example, as shown in fig. 2, at a main board end of the tablet personal computer, an ARM processor is adopted, and two MIPI interfaces are provided to connect the main screen and the auxiliary screen respectively, so as to realize simultaneous display or separate display of two screens. As shown in fig. 3, the sub-screen module includes an Eink screen (i.e., the sub-screen) interface, an Eink screen gate-source voltage driving circuit, and a hardware TCON circuit. Specifically, a Pin of the connector Pin can be reserved at a corresponding position of the back of the tablet computer through a high-speed interface connector, a corresponding connector interface is configured on the auxiliary screen module, and signals of the auxiliary screen module comprise MIPI interface signals displayed by an LCD, control signals of a TCON chip special for an Eink screen and power supply signals (VBAT) required by the whole module.

In some embodiments, after the external auxiliary screen module is detected, the scheme presents prompt information for selecting the screen on the main screen; specifically, a selection prompt (menu) for switching screens may pop up on the main screen, and if the user selects to operate only the sub-screen, the CPU is notified to turn off the operating circuit and the power supply of the main screen, and the current user operation interface is displayed on the sub-screen. Here, customized launcher (rom) design may be performed for an operating system of a terminal device such as a tablet computer, so as to implement a dual-screen interactive design.

For example, it is possible to facilitate the user to switch between the main screen and the sub-screen by setting a special menu or button.

In some embodiments, if the user's selection operation is to select to display the interface on the secondary screen separately; wherein the method further comprises: stopping power supply to the main screen. For example, when the user selects the sub-screen reading mode, the system can turn off the power supply and the working interface of the main screen, so that the power consumption of the whole machine is reduced, the main CPU is still in a working state at the moment, and the user operation interface can be displayed through the sub-screen. The electronic ink screen can be expanded to serve as the auxiliary screen, the requirement of deep reading of a user can be met under the condition that the main screen is closed, the eyesight health of the user is protected, and the power consumption of the system is reduced. If be applied to the panel computer product of education trade with this scheme, when switching to the electronic ink screen reading mode, can avoid traditional audio-visual amusement and the interference that various advertising message propelling movement brought, can not only protect student user's eyesight health, can also bring immersive reading experience for the user.

And step S103, stopping power supply to the auxiliary screen module based on the removal operation of the user, and displaying an interface on the main screen.

For example, before the sub-screen is removed, the user may notify a terminal device such as a tablet computer through a specific menu button to turn off the interface power and signal. In addition, the Hall sensor detects that the magnetic flux becomes small, corresponding interrupt signals are output to the CPU, and then the CPU turns off corresponding control signals and a power supply, so that the risk of live operation when the auxiliary screen module is inserted again is prevented.

In some embodiments, a specially designed plug-and-play interface can be adopted at the tablet personal computer end, so that hot plugging and unplugging of the display screen are realized, the electric brush screen is ensured to be detected firstly and then be electrified, when the secondary screen is detected to be unplugged, the system can close the corresponding interface and the power supply and automatically switch back to the main screen for displaying, and the risk that the interface is still electrified when the secondary screen is plugged is prevented.
