Abstract： Aiming at the problem of time-consuming and lengthy problems caused by tedious manual operation in the traditional display audio test process, this paper combines the basic principles of display audio test to propose a display audio automatic test system based on virtual instrument technology. The program designs the communication circuit between the PC and the display to be tested, and realizes remote communication through the mixed programming of LabVIEW and VC++. Then, the control of the measuring instrument is realized through the related tools of the virtual instrument. Finally, combined with the audio test steps，the system test process is designed to realize the automatic execution of the full test project. Experimental verification shows that compared with manual operation, the system has a higher degree of automation under the same accuracy, and the average test time is shortened by 84.25%, which provides a practical reference scheme for automatic audio testing of display devices.
