Display driving circuit and system with same

The embodiment of the invention provides a display driving circuit. The display driving circuit comprises a receiving decoding module, a display data processing module and an address data processing module, wherein the receiving decoding module is used for decoding received data, carrying out separation to form display data and address data, and inputting the display data and the address data into the display data processing module and the address data processing module respectively, the display data processing module is used for outputting driving signals according to the display data, and having control over an LED display device, and the address data processing module is used for receiving and storing the address data, and then outputting the address data in a forwarding mode. The embodiment of the invention further provides a display control system. According to the scheme, writing of the address data in a serial connection mode and writing of the display data in a parallel connection mode can be carried out on a parallel dedicated integrated circuit with the function of independent control over lamps, production efficiency and reliability of LED display driving chips are improved, the cost of a display system is reduced, and system performance is optimized.
