Ultra-high resolution display system and display control method

Abstract

The invention relates to the field of video display and discloses an ultrahigh-resolution display system and a display control method. The ultrahigh-resolution display system comprises a video card, a video memory duplication unit, a display storage unit, a bus switch and at least two video output units. The video card comprises an internal bus and an external bus, the internal bus is connected with a processor of a computer where the video card is positioned, and the external bus is connected with the bus switch; the bus switch is connected with the external bus and the video output units; each video output unit comprises a video memory and an interface; the video memory duplication unit directly duplicates video signals in the display storage unit into the video memories of the video output units through the external bus and the bus switch. Due to the fact that the video signals in the display storage unit are directly duplicated into the video memories of the video output units through the external bus, ultrahigh-resolution GIS (geographic information system) base maps, CAD (computer-aided design) drawings, application control interfaces and the like can be displayed on a large screen formed by a plurality of display screens.

Description

technical field [0001] The invention relates to the field of video display, in particular to an ultra-high resolution display system and a display control method. Background technique [0002] Screens with a large field of view are usually required in large-scale monitoring or high-end conference projects, so large-screen splicing technology is imperative. At present, the large-screen splicing technology can realize the window opening of the video on the large screen, roaming display, and support for zooming in any proportion, but it cannot support the display of ultra-high-resolution geographic information system (Geographic Information System, referred to as "GIS") Maps, computer-aided design (Computer-Aided Design, referred to as "CAD") drawings, etc. Therefore, although the resolution of multiple display sub-screens combined by the corresponding large-screen splicing can be extremely high, the corresponding ultra-high-resolution GIS maps and CAD drawings cannot be input...

AI Technical Summary

Problems solved by technology

At present, the large-screen splicing technology can realize the window opening of the video on the large screen, roaming display, and support for zooming in any proportion, but it cannot support the display of ultra-high-resolution geographic information system (Geographic Information System, referred to as "GIS") Maps, computer-aided design (Computer-Aided Design, referred to as "CAD") drawings, etc. Therefore, although the resolution of multiple display sub-screens combined by the corresponding large-screen splicing can be extremely high, the corresponding ultra-high-resolution GIS maps and CAD drawings cannot be input to the corresponding display sub-screen for display, because all current display interfaces cannot output ultra-high-resolution images

[0003] Due to the limitations of the processing performance of the graphics card and the transmission bandwidth of the video cable, the corresponding video image cannot reach a high resolution. The output interface is used to realize ultra-high-resolution video images, but the corresponding output interface can only support up to 6 resolutions of 1080P (1920x1080), which cannot be larger, which limits the ultra-high-resolution GIS map. CAD drawings, etc. are displayed on the large screen

Even multi-head graphics cards can only support a resolution of 10 to 20 million, and cannot support ultra-high resolutions of tens of millions or even hundreds of millions
