Said signal processing unit pursues to the said Third Road vision signal of said frame cell stores and the four tunnel vision signal that row/reorganization line by line interweaves; Extract the odd column/odd-numbered line of said Third Road video signal video frame and the even column/even number line of corresponding said the four road video signal video frame; With first the odd column/odd-numbered line of said Third Road video signal video frame and first even column/initial row of even number behavior of corresponding said the four road video signal video frame; Odd column/odd-numbered line to the said Third Road video signal video frame that extracted pursue the column interleaving reorganization with the even column/even number line of corresponding said the four road video signal video frame, obtains said Third Road vision signal and said the four tunnel vision signal vision signal after recombinating that interweaves.
13. the video playing terminal of display system as claimed in claim 11; It is characterized in that; The refreshing frequency of said display screen is not less than 120Hz; And road vision signal in the two-path video signal of said display screen after odd-numbered frame is play the said reorganization that interweaves, another road vision signal in the two-path video signal after even frame is play the said reorganization that interweaves.
14. the video-see terminal of a display system; Said display system also comprises a video playing terminal; It is characterized in that; Said video-see terminal comprises at least one first liquid crystal shutter glasses; Said first liquid crystal shutter glasses has one of two polarization directions of polarization direction and the polaroid of said video playing terminal identical polarizing coating in the liquid crystal layer surface coverage of eyeglass, said video-see terminal is used to receive the synchronous playing signal that said video playing terminal is sent, and according to the said liquid crystal layer of said synchronous playing unblanking/close.
15. the video-see terminal of display system as claimed in claim 14; It is characterized in that; Said video-see terminal also comprises at least one second liquid crystal shutter glasses, and said second liquid crystal shutter glasses has another identical polarizing coating in two polarization directions of polarization direction and the polaroid of said video playing terminal in the liquid crystal layer surface coverage of eyeglass.
