Multi-screen display system using V-BY-ONE signals

The utility model discloses a multi-screen display system using V-BY-ONE signals. The multi-screen display system comprises a signal source, a plurality of V-BY-ONE distribution boards and a plurality of displays, the signal source comprises a CPU (Central Processing Unit), a THCV215 chip and an RS485 interface, wherein the THCV215 chip and the RS485 interface are respectively connected with the CPU; the V-BY-ONE distribution board comprises a THCV2712 chip and a THCV216 chip, wherein the THCV216 chip is connected with the THCV2712 chip, and the THCV216 chip is connected with the THCV2712 chip. And the V-BY-ONE distribution board is connected with the display through the THCV216 chip. Parallel LVDS signals sent by a CPU are serialized into V-BY-ONE signals through a THCV215 chip, the V-BY-ONE signals are output to a THCV2712 chip, the THCV2712 chip copies the V-BY-ONE signals into two paths of identical V-BY-ONE signals and outputs the two paths of identical V-BY-ONE signals to a corresponding THCV216 chip an
