The invention discloses an integrated driving device used for an LED advertisement display screen, which belongs to the field of LED driving control and solves the problems of high cost, processing complexity and easy damage due to more elements in the conventional method for driving display data of an LED driving integrated circuit. The integrated driving device comprises a data buffering unit and a decoding control unit, wherein the data output end of the data buffering unit is connected with the data input end of the decoding control unit. Through the integrated scheme adopted by the invention, the number of chips in each unit plate is reduced by more than half, and meanwhile the interconnection of circuits between the chips is reduced due to the reduction of the chips, so the processing cost is remarkably reduced; and some functions such as protection function realized by the conventional scheme are realized inside the chips, so devices such as a diode or a resistor-capacitor and the like at the periphery of the conventional chip do not need to be increased; therefore, the cost is reduced, and the fault rate and the maintenance/repair cost are also reduced.
