The invention discloses a multi-screen projection method and device and a vehicle, and relates to the technical field of vehicles, and the method comprises the steps: responding to the access of a projection screen peripheral, and receiving projection screen data and projection screen attribute information sent by the projection screen peripheral; transmitting the projection screen attribute information of the projection screen peripheral to the first display system and the second display system respectively; based on the screen projection attribute information, controlling screen projection data sent by the screen projection peripheral to perform screen projection in the first display system; in response to a multi-screen projection request sent by the second display system, controlling to start a video signal deserializer in the first display system; and transmitting the projection screen data to a second display system based on the video signal deserializer so as to complete synchronous display of the projection screen information in the first display system and the second display system. Compared with the prior art, the first display system and the display system are connected based on the video signal deserializer to realize simultaneous screen projection display between the two systems, so that the images simultaneously displayed between the two systems are more synchronous and smoother.

    本公开公开了多屏幕投屏的方法及装置、车辆,涉及车辆技术领域,包括:响应于投屏外设的接入,接收投屏外设发送的投屏数据和投屏属性信息;将投屏外设的投屏属性信息分别传输至第一显示系统和第二显示系统;基于投屏属性信息,控制投屏外设发送的投屏数据在第一显示系统中进行投屏;响应于第二显示系统发送的多屏幕投屏请求,控制启动第一显示系统中的视频信号解串器;基于视频信号解串器将投屏数据传输至第二显示系统,以完成投屏信息分别在第一显示系统与第二显示系统的同步显示。与相关技术相比,本公开通过将第一显示系统与显示系统基于视频信号解串器进行连接来实现两系统之间同时投屏显示,使得两系统之间同时显示的图像更同步且流畅。
