Problems solved by technology

However, limited by the chip architecture and operating system architecture design, on the existing Linux platform, usually only some applications that can be displayed simultaneously on dual-screen or multi-screen
In such applications, one display screen can only be used as an extension of another display screen, and two different screens can only display the same content. This type of technology has become more and more difficult to meet the actual needs

Abstract

The embodiment of the invention discloses a multi-screen display control method and device, an embedded processing system, a video controller and a storage medium. The multi-screen display control method comprises the steps that display controller nodes in an equipment information list are matched in sequence, and a specified function is executed after matching succeeds every time so as to obtaininformation of the display controller nodes; constructing a display storage space corresponding to the information of each display controller node according to the acquired information of each displaycontroller node, and generating a display content input node corresponding to each display storage space; to-be-displayed content is received through the multiple display content input nodes, and thereceived to-be-displayed content is input into the corresponding display storage space; and displaying and outputting the to-be-displayed content in the display storage space corresponding to each display controller node. According to the embodiment of the invention, different display contents can be played on a plurality of display devices.

Description

technical field [0001] The present invention relates to the technical field of display control, in particular to a multi-screen display control method, a multi-screen display control device, an embedded processing system, a video controller and a storage medium. Background technique [0002] With the rapid development of electronic technology, embedded electronic devices have been widely used in industrial control, consumer electronics and other fields. However, limited by the design of chip architecture and operating system architecture, on the existing Linux platform, only some applications that can be displayed synchronously on dual screens or multiple screens can usually be realized. In such applications, one display screen can only be used as an extension of another display screen, and two different screens can only display the same content. This type of technology has become more and more difficult to meet the actual needs. Contents of the invention [0003] Embodi...
