Abstract
The disclosure provides a device for receiving a single-ended signal of an LED control card and forwarding as differential signals, including a parsing unit, a control unit, an SRAM and a differential output unit; the parsing unit is used for receiving and parsing data, latch and clock signals sent by the control card; the SRAM is used for storing display data of a parsing result; the control unit is used for processing commands of the parsing result, accessing the SRAM, modifying the display data transmitted by the parsing unit in the SRAM, and filling the SRAM for provision to a back end for output display; and the differential output unit is used for obtaining differential signals based on a processing result of the control unit.
