It is necessary to use a data synthesizing device or a plug-in to serially encode left and right eye data, that is, ' Synthetic 'or 'reuse', LED The judgment accuracy of the display receiving end needs to be nanosecond or less. In some cases, the left and right eye image source data is greatly different due to format or other reasons, and it is technically difficult to adopt 'mixed image transmission'.
技术问题technical problem
本发明的目的是提供一种新的三维LED显示***，将左右眼图像数据由混编图像传输改为独立图像传输。  It is an object of the present invention to provide a new three-dimensional LED display system that converts left and right eye image data from a mixed image transmission to an independent image transmission.
