The invention provides a combination instrument of an automobile. The combination instrument comprises a combination instrument module and a combination instrument LCD screen, wherein the combination instrument module transmits display information to a main chip of a sound through a communication bus; the main chip of the sound drives the combination instrument LCD screen to display the information through the communication chip. Since the combination instrument LCD screen is driven by present functions of the main chip of the sound to display the information, a display driving circuit module is omitted in hardware of the combination instrument module when the cost of the main chip of a sound system is not increased. Therefore, the hardware circuit of the combination instrument module can be simplified greatly, and the cost of a combination instrument system is reduced relatively greatly.
