Quadruple-high-definition liquid crystal color screen input interface

A quadruple-high-definition liquid crystal color screen input interface comprises a DP interface, wherein the forefront end of the DP interface is provided with a DPHUB, the DPHUB is divided into two paths which are connected with two DP interface chips respectively, and the DP interface chips are connected with the same vision signal processor. The DPHUB can support the 4LANE maximum support communication rate to be 21.6G, and can receive vision signals of 3840X2160@60Hz. The DPHUB is connected to the DP interface chips through two DP interface signal wires which can transmit DP interface signals, the DP interface chips can convert the DP signals to RGB vision data signals, and the RGB vision data signals are transmitted to the vision signal processor to process through the signal wires. The quadruple-high-definition liquid crystal color screen input interface is simple and compact in structure, through split transmission of flow of the DPHUB and the DP interface chips, transmission quantity of the flow is improved, data flow can be transmitted to the vision signal processor in good order, and image quality and refreshing frequency of a quadruple-high-definition liquid crystal color screen are guaranteed.
