The invention discloses a vehicle-mounted same-screen control method, a vehicle-mounted same-screen control device, electronic equipment, a storage medium and a vehicle, and the method comprises the steps that a screen sending end and a screen receiving end establish a data link for synchronous display, and the screen sending end monitors the screen content change of the screen sending end; if the screen content of the screen sending end changes, reading the screen data in the video memory; the screen data comprises the screen frame data of the pixel data and the coordinate data corresponding to the screen content change of the screen sending end; the screen sending end sends the screen data of the screen sending end in the video memory; a screen receiving end receives the screen data; and the screen receiving end controls the screen of the screen receiving end to refresh screen display according to the screen data. According to the scheme, the frame data only containing the pixel data and the coordinate data is transmitted, so that the bandwidth requirement is greatly reduced, and meanwhile, the refreshing efficiency of same-screen display is improved.
本申请公开了一种车载同屏控制方法、车载同屏控制装置、电子设备、存储介质及车辆,方法包括,屏幕发送端与屏幕接收端建立数据链路,用于同步显示,其中,屏幕发送端监听屏幕发送端屏幕内容变化;若,屏幕发送端屏幕内容有变化,则读取显存中屏幕数据;所述屏幕数据包括,对应屏幕发送端屏幕内容变化的像素数据和坐标数据的屏幕帧数据;屏幕发送端发送显存中屏幕发送端所述屏幕数据;屏幕接收端接收所述屏幕数据;屏幕接收端根据所述屏幕数据,控制屏幕接收端屏幕刷新屏幕显示。通过上述方案,传递只包含像素数据和坐标数据的帧数据,使带宽需求大大降低的同时,增加同屏显示的刷新效率。
