With the maturity of digital display technology, its application scope is also more and more extensive, and there are more and more application cases in the protection and inheritance of minority hand-weaving skills. This paper builds a general framework for the design of the digital inheritance system for the handloom weaving techniques of the Miao family in southern Sichuan, and applies three-dimensional modeling technology, three-dimensional animation technology, digital imaging technology and interactive interface design to complete the preliminary establishment of the digital display system for the handloom weaving techniques of the Miao people in southern Sichuan. Combined with the information dissemination characteristics of mobile intelligent terminals, relevant improvement programs are proposed. At the same time, the optimization and improvement of the digital display system is further improved to meet the needs of users. Comparing the users’ experience and perception of the digital display system, the system designed in this paper is superior to R-Space in terms of functional scope and technology, and the average score of the system designed in this paper is 4.193, which is higher than the score of 3.985 of the R-Space system, and the system designed in this paper has a higher score. At the same time, the user’s satisfaction with the system’s interactivity is more stable in the three aspects of login start, system home page, and Chuannan humanities resources. In the login start, the scores of very satisfied, more satisfied, and general are 2, 3, and 2.5 respectively, which indicates that the user’s experience of this paper’s system is better.
