Device based on FPGA spliced screen and self-adaptive display method thereof

Abstract

The invention discloses a device based on a field programmable gate array (FPGA) spliced screen and a self-adaptive display method thereof. A plurality of splicing units are arranged in an array mode, the splicing units in a single row or a single column are connected to sub FPGA modules, each sub FPGA module is connected to a main FPGA module in parallel, the method is applied to the main FPGA module, and the self-adaptive display method is applied to the main FPGA module. The method comprises the following steps: obtaining first screen display information and first position information of a splicing unit through the sub FPGA module; judging whether the splicing unit is damaged or not according to the first screen display information, performing video picture clipping according to the position information, and obtaining a clipping picture, wherein the first clipping picture is transmitted to the splicing unit through the sub-FPGA module to be displayed. The spliced screen is high in expandability, and an oversized spliced screen can be quickly expanded without secondary development; In addition, through plugging and dismounting, rapid maintenance can be realized under the condition that the display is not influenced.

Description

technical field [0001] The invention relates to the communication field, in particular to an FPGA-based splicing screen device and an adaptive display method thereof. Background technique [0002] Screen splicing refers to dividing a complete image signal into N blocks and assigning them to N video display units. [0003] With the advent of the information age, the rapid development of computer multimedia technology, the widespread application of network technology, the establishment of command and monitoring centers and network management centers, as well as the conduct of temporary meetings and technical lectures, all desire large-screen, multi-color, High brightness, high resolution display effect. The large-screen projector technology developed rapidly in recent years has become an effective way to solve the problem of color large-screen display. The scope of application has been further expanded, and the market has become increasingly active due to the growth of demand...

Problems solved by technology

[0004] However, the current existing screen splicing is mainly based on rough assembly of large-size display panels, and then the data is distributed and transmitted by the control system. splicing screen

In addition, such splicing is limited in terms of equipment maintenance and expansion. After one piece is removed, the entire graphic display effect will be greatly affected
