Abstract

The embodiment of the invention discloses a multi-screen abnormal display method and device, main display equipment, a system and a storage medium; the method is applied to the main display equipment,and the method comprises the following steps: responding to a playing operation, and generating a playing instruction; encoding the to-be-split-screen display data according to a set protocol, wherein the set protocol comprises a matching relationship between the to-be-split-screen display data and the device identifier of each slave display device; sending the encoded to-be-split-screen displaydata to corresponding slave display equipment according to a set protocol; if response instructions from all the slave display devices are received, sending the playing instruction to each slave display device to indicate each slave display device to play according to the to-be-split-screen display data, wherein each response instruction is generated after each slave display device receives the to-be-split-screen display data corresponding to the device identifier of the slave display device. The limitation of the spatial distance between the master display device and each slave display deviceis broken through, and multi-screen different display is realized.

Description

technical field [0001] Embodiments of the present application relate to multi-screen display technologies, and in particular to a multi-screen differential display method, device, main display device, system, and storage medium. Background technique [0002] In order to meet diverse display requirements, a multi-screen display technology has been developed. The current multi-screen display includes multi-screen simultaneous display and multi-screen different display. Among them, the multi-screen different display is to display different content from the first display on the second display connected to the Android device, and the modules in it can be controlled through the keys or touch of the device. [0003] In related technologies, the Android system supports up to two screens with different displays. If there is a need for multiple screens with different displays, only a USB (Universal Serial Bus, Universal Serial Bus) external graphics card can be used to increase the d...
