Description

Technical field [0001] The invention relates to the technical field of multi-screen splicing display, in particular to a multi-screen splicing device and a multi-screen splicing method. Background technique [0002] In the current field of multi-screen display, there are two ways to use a single graphic processing unit (Graphic Processing Unit, GPU) and multiple GPUs. Among them, the solution of using multiple GPUs is usually composed of multiple graphics cards distributed in multiple graphics cards. A general-purpose GPU generates high-resolution multi-screen signals. This solution can achieve high-resolution multi-screen splicing. However, because general-purpose GPUs do not have a mechanism for collaboratively completing 3D images, it is difficult for multiple general-purpose GPUs to coordinate operations to complete a complete 3D image. Therefore, the current multi-screen splicing display of multiple GPUs is limited to 2D display. The invention patent application with applica...

[0002] In the current field of multi-screen display, there are two ways of using a single Graphic Processing Unit (Graphic Processing Unit, referred to as GPU) and multiple GPUs. A general-purpose GPU generates high-resolution multi-screen signals. This solution can achieve high-resolution multi-screen splicing. However, since there is no mechanism for general-purpose GPUs to cooperate to complete 3D images, it is difficult for multiple general-purpose GPUs to cooperate to complete a complete 3D image. Therefore, the current multi-screen splicing display of multiple GPUs is limited to 2D display. The invention patent application with the application number of 200810026939.X discloses a multi-screen splicing method and device. The bandwidth standard of the output port adjusts the output refresh rate of the GPU, so that the output resolution of the GPU meets the requirements of the total resolution of the splicing, and then divides the output video data, and performs standard splicing under the action of the corresponding standard pixel clock Output, to achieve high-resolution multi-screen splicing, this kind of multi-screen display scheme that uses a single GPU to output the complete 3D image through the video output port and display it after image segmentation can meet some high-resolution However, the methods in the prior art all transmit the displayable image to the display unit through the image output port of the GPU for display. Due to the number of image output ports of the existing general-purpose GPU and the Due to the limitation of bandwidth, the resolution that can be output and the number of mosaic units that can be driven are small, and it is difficult to output ultra-high-resolution 3D images. At the same time, since the video ports of each general-purpose GPU are the same, it is not flexible in applications. The number of rows and columns can be configured accurately (for example, GPU usually only has two video ports, so it is inconvenient to configure a splicing system with an odd number of screens), which limits the application of multi-screen splicing display technology
