The embodiment of the invention discloses a 4K splicing processor and a 4K splicing display
system. The 4K splicing processor comprises a
driving circuit used for
processing a 4K resolution
signal, the
driving circuit comprises an
FPGA chip U5, TVS array chips U10, U11, U12 and U13 and DP
signal line connectors CN9 and CN10; the model of the U5 is Spartan-6, the models of the U10, the U11, the U12 and the U13 are all RClamp0524P, the CN9 is connected with the U5 through the U10 and the U11, and the CN10 is connected with the U5 through the U12 and the U13; the U5 receives the input 4K resolution
signal through the CN9 to process the 4K resolution signal and outputs the processed 4K resolution signal through the CN10 to achieve 4K resolution signal looping. According to the 4K splicing processor and the 4K splicing display
system, the problem that 4K splicing display
system equipment is complex is solved.
