This paper introduces the LCD display system of the voice and billing design, backend circuit design, and relevant theoretical analysis and so on. The paper details the method and principle of the circuit design, the functions of the circuit and the methods of the data processing. In software design, it introduces the work flow of the software design, the program design of the LCD display and the voice chip software design. Through the software and hardware design, a plete LCD display system of the voice and billing had pleted by a speech broadcast system and a liquid crystal display parts.
