LED display screen system architecture supporting multifunctional display

Abstract

The invention discloses an LED display screen system architecture supporting multifunctional display, which comprises a first main control card, a second main control card, a sending card and a display module, and the first main control card provides a first video signal and outputs the first video signal to the second main control card; the second main control card is used for receiving any one or more of the two-dimensional video signal, the three-dimensional video signal and the first video signal, randomly switching, splicing, moving, zooming, superposing and performing cross-screen roaming to generate a second video signal, and outputting the second video signal to one or more sending cards; and the sending card receives the second video signal, cuts the second video signal, packagesthe second video signal and distributes the second video signal to receiving cards of one or more display modules. According to the invention, through the processing of the second main control card, the LED display screen can independently display a two-dimensional picture or a three-dimensional picture, and the two-dimensional picture and the three-dimensional picture can be displayed at the sametime, so that the functions are rich, and the application in various occasions is satisfied.

Description

technical field [0001] The present invention relates to the technical field of LED display screens, in particular to a system architecture of LED display screens supporting multi-functional display. Background technique [0002] Both the patent document CN 110633063A and the patent document CN110569012A are existing all-in-one system architectures for LED display screens. The main control card in the existing all-in-one system architecture can only realize two-dimensional display, but cannot realize three-dimensional display. [0003] Patent document CN 104243964 A discloses a stereoscopic LED display control system and method, and a display control card. The control system (that is, the system architecture) in this patent document needs to be equipped with a special main controller in order to realize three-dimensional display on the LED display screen, which also requires a special main control card. Moreover, this main control card can only realize three-dimensional dis...
