Embodiment 1
[0039] This embodiment discloses a method for dual-screen differential display in a vehicle entertainment system. The vehicle entertainment system is based on an Android system, and the Android version is less than or equal to 9.0.
[0040] In this embodiment, the vehicle entertainment system includes vehicle host hardware and a main screen (the first DisplayDevice) and a secondary screen (the second DisplayDevice) connected to the vehicle host hardware.
[0041] Such as figure 1 As shown, the method includes:
[0042] S10. Customize the display manager (DisplayManager) and Surfaceflinger of the in-vehicle entertainment system, so as to expand the docking driver into a physical path of dual display screens, so that the display device information of the secondary screen is consistent with that of the main screen.
[0043] In this step, the display manager (DisplayManager) is the management of the display device, that is, the management of the display screen (the above-mentione...

The invention relates to a double-screen different display method in a vehicle-mounted entertainment system, the vehicle-mounted entertainment system is based on an Android system; the vehicle-mounted entertainment system comprises vehicle-mounted host hardware, and a main screen and an auxiliary screen which are connected with the vehicle-mounted host hardware, and the method comprises the following steps: customizing a display manager and a Surfaceflinger of the vehicle-mounted entertainment system, and expanding the docking drive into a double-display-screen physical path, so that the display equipment information of the auxiliary screen is consistent with that of the main screen; performing double-display-screen expansion on the window state of the window management layer so as to respectively display the window states of two different applications on a main screen and an auxiliary screen; and carrying out expansion support of a double-display-screen application stack on the application management layer so as to place the application which needs to be placed on the secondary screen. According to the invention, a host system is realized to support multi-screen display, applications can be flexibly configured or customized to be displayed on different display screens, the hardware cost of a cockpit system is reduced, non-secondary screen display is basically not different from primary screen display, and very good experience is provided for a user.
Description
technical field [0001] The invention relates to the technical field of terminal applications, in particular to a method for dual-screen differential display in a vehicle-mounted entertainment system. Background technique [0002] Now the car cockpit system has multi-screen functions, mainly in the following ways: 1. Use more hosts to realize, because it is realized by multiple hardware hosts, resulting in doubled cost; 2. One host is connected to multiple screens, only one The main screen of the system and other screens are mainly realized by the output of video streams. This solution has limited display content. Either the current main screen information is displayed synchronously, or some applications are deeply customized, and the information that the application itself needs to display is independently transmitted to another screen. [0003] Therefore, non-main screen users have limited choices and it is difficult to expand, such as supporting user-controlled operations...
