Recently, 3D is a convergence technology that combines various technologies, and it is changing the
paradigm in the traditional industry and advancing the convergence industry. In particular, domestic
companies have competitiveness in 3D technology as well as corporations, government agencies, research
institutes and universities. However, as it is an immature industry, it is time for a strategic approach.
Therefore, this paper analyzes patent trends in medical, education / training, advertising / exhibition, entertainment, construction, defense / military, distribution / logistics by statistical techniques. Based on this,
we aim to analyze trends and present implications. This paper uses patent data from January 1, 1990 to
February 27, 2017. As a result of the study, the patents trend of the entire 3D convergence industry is on
the increase of patent application, and the technology market of the 3D convergence industry shows a
typical growth phase. In particular, the 3D display market and the 3D application market are expected to
continue to expand. In addition, domestic 3D technology and application equipment have a relative
advantage. However, considering the future expansion of 3D convergence industry, intensive policy support
and fostering of 3D contents and application fields are required.
