Abstract

The embodiment of the invention discloses an application screen projection method and device, a vehicle-mounted terminal and a readable storage medium. The method comprises the steps that an application program installed in a mobile operation system is connected with a preset virtual display screen; synthesizing an application interface of the application program in the canvas of the virtual display screen; transmitting the application interface to a real-time operating system through the shared memory channel; and controlling the real-time operating system to display the application interface on the target display screen. According to the embodiment of the invention, the operation performance of the vehicle-mounted terminal can be improved.

Description

technical field [0001] The present application belongs to the technical field of information processing, and in particular relates to an application screen projection method, device, vehicle-mounted terminal and readable storage medium. Background technique [0002] With the continuous upgrading of the vehicle-mounted terminal technology, various application programs can be installed in the vehicle-mounted terminal, and after the vehicle-mounted terminal starts the application program, the interface of the application program can be displayed on the corresponding display screen. In order to facilitate drivers to quickly grasp various types of application information such as navigation information and communication information, multiple display screens controlled by vehicle-mounted terminals often display content at the same time. [0003] At present, by configuring a display port of a display framework (OpenWF Display, WFD) for the mobile operating system, the content of the...
