Furthermore, the necessary, known, and customary elements from commercially available technical solutions are not illustrated, so the clarity of the embodiments is not impaired. DESCRIPTION OF THE EXECUTION FORMS
[0021] The following description sets out numerous specific details to enable a thorough understanding of this application. However, it is obvious to those skilled in the art that this invention can be implemented without these specific details. Under other circumstances, well-known methods are not described in detail so as not to obscure this invention.
[0022] In this description, the terms “an embodiment”, “an exemplary embodiment”, or “a further exemplary embodiment” are to be understood as meaning that the specific features, structures, or properties described in connection with that embodiment or exemplary embodiment are included in at least one embodiment of the invention, and that they do not necessarily all relate to the same embodiment or exemplary embodiment. Furthermore, specific features, structures, or properties may be applied in any suitable combination and / or subcombination to one or more embodiments or exemplary embodiments.
[0023] Fig. Figure 1 shows a schematic block diagram of a management system 10 for a vehicle screen according to an embodiment of the invention, wherein the vehicle screen comprises a main screen and at least one secondary screen (not shown). The system 10 comprises a power supply module 102 and a display module 104.
[0024] The power supply group module 102 comprises a main screen power management module 1021 and a secondary screen power management module 1022. The main screen power management module 1021 is configured to manage the power state of the main screen. The secondary screen power management module 1022 is configured to manage the power state of at least one secondary screen.
[0025] The display group module 104 comprises a main screen display management module 1041 and a secondary screen display management module 1042. The main screen display management module 1041 is configured to manage the display state of the main screen. The secondary screen display management module 1042 is configured to manage the display state of at least one secondary screen.
[0026] In one embodiment, the main screen generally refers to the screen for the driver, and the secondary screen generally refers to the screen for the front passenger and / or the screen for the rear seat occupants. In another embodiment, it is conceivable that the main screen and the secondary screen could be defined as needed.
[0027] Advantageously, the power and screensaver programs of the main and secondary displays can be controlled separately to prevent them from interfering with each other. This is achieved by managing the main display's power management and display management modules, and the secondary display's power management and display management modules. For example, if a user operates the main display, this will not affect the secondary display's entry into or exit from screensaver mode, and vice versa.
[0028] In one embodiment, the system 10 further comprises a screen monitoring module (not shown). The screen monitoring module is configured to monitor the display state of the main screen and the at least one secondary screen and to output corresponding screensaver trigger information after the main screen or the at least one secondary screen has been inactive for a predetermined period (which is configurable by the user). The screensaver trigger information includes identity information (e.g., the screen ID) of the main screen or the at least one secondary screen that should be put into screensaver mode.In one embodiment, it indicates that the main screen or the at least one secondary screen will enter screensaver mode if the screen monitoring module monitors an inactive state of the main screen or the at least one secondary screen for a period of, for example, 2 minutes, 3 minutes, or another preset duration. Before entering screensaver mode, the screen monitoring module sends a screensaver trigger message indicating that the main screen or the at least one secondary screen has entered screensaver mode.
[0029] The screen monitoring module sends the screensaver trigger information to the corresponding power management module of the main screen 1021 or to the corresponding power management module of the secondary screen 1022, depending on the screen identity information contained in the screensaver trigger information.
[0030] In one embodiment, the power management module of the main screen 1021 is further configured to adjust the power of the main screen in response to the received screensaver trigger information, including the identity information of the main screen, in order to put the main screen into screensaver mode. The power management module of the secondary screen 1022 is further configured to adjust the power of the secondary screen in response to the received screensaver trigger information, including the identity information of the secondary screen, in order to put the secondary screen into screensaver mode.
[0031] For example, if the screen monitoring module detects an inactive state of the main screen being viewed by the driver for a period of, say, 2 minutes, 3 minutes, or another predetermined duration, the screen monitoring module sends a screensaver trigger signal indicating that the main screen is entering screensaver mode and includes the main screen's identity information. In response to this received screensaver trigger signal and the main screen's identity information, the main screen's power management module adjusts the main screen's power consumption to bring it into screensaver mode. For example, it reduces the main screen's power consumption to put it into sleep mode or activate a screensaver.At this point, the passenger in the front seat can continue to operate the corresponding secondary screen. This is not affected by the main screen's screensaver mode. This improves the usability of the secondary screen for the vehicle occupant.
[0032] In one embodiment, the system 10 further comprises a user input monitoring module (not shown). This module is configured to monitor and receive a user input event from the main screen and the at least one secondary screen. The user input event contains identity information of the corresponding main screen or secondary screen receiving the user input. The user input monitoring module sends the user input event to the corresponding display management module of the main screen or to the corresponding display management module of the secondary screen, depending on the screen identity information contained in the screensaver trigger information.
[0033] In one embodiment, the display management module of the main screen 1041 is further configured to adapt the main screen in response to the received user input event containing the identity information of the main screen, so that the main screen displays the appropriate content or exits screensaver mode. The display management module of the secondary screen 1042 is further configured to adapt the secondary screen in response to the received user input event containing the identity information of the secondary screen, so that the secondary screen displays the appropriate content or exits screensaver mode.
[0034] A user input event on at least one secondary screen is, for example, the activation and use of an application program (APP) on the corresponding secondary screen by the passenger in the front seat. The user input monitoring module then sends the user input event to the corresponding display management module of the secondary screen, depending on the relevant identity information of the secondary screen contained in the user input event. In response to the received user input event with the relevant identity information of the secondary screen, the display management module of the secondary screen adjusts the corresponding secondary screen to display the appropriate content.
[0035] A user input event on at least one secondary screen is, for example, a click on the corresponding secondary screen (in screensaver mode) by the passenger when the secondary screen viewed by the passenger is in screensaver mode. The user input monitoring module then sends the user input event to the corresponding display management module of the secondary screen, depending on the screen's identity information contained in the screensaver trigger information. In response to the received user input event with the corresponding identity information of the secondary screen, the display management module of the secondary screen adjusts the corresponding secondary screen to exit screensaver mode.
[0036] Thus, the display state of the secondary screen or the exit of the screensaver mode can advantageously be controlled separately, so that they are not affected by the state of the main screen, and vice versa, by using a user input monitoring module and managing the main screen through the main screen's display management module and managing the secondary screen through the secondary screen's power management module.

[0040] In step S2041, the display state of the main screen is managed by a main screen display management module.
[0041] In step S2042, the display state of the secondary screen is managed by a secondary screen display management module.
[0042] In one embodiment, the method 100 may further comprise: monitoring the display state of the main screen and the at least one secondary screen by a screen monitoring module; and outputting a corresponding screensaver trigger information when the main screen or the at least one secondary screen is inactive for a predetermined period, wherein the screensaver trigger information contains identity information of the main screen or the at least one secondary screen that should be put into screensaver mode; sending the screensaver trigger information by the screen monitoring module to the corresponding power management module of the main screen or to the corresponding power management module of the secondary screen, depending on the identity information of the screen contained in the screensaver trigger information.
