Establishing an R&D strategy based on a patent analysis of the display industry

Abstract

This study proposes a method for establishing an R&D strategy that can be used by R&D decision-makers in companies and countries in the display industry in order to develop an effective technology. In order to develop a technology tree for the display industry, the entire technology is classified into three main category levels (LCD, FD, and OLED), 19 sub-category levels, and 69 sub-subcategory levels, based on the opinions of the experts in the display industry and on the reports from related technologies. Next, the technology area is examined by conducting a patent indicator analysis on each of the 69 sub-subcategory levels and the technological life cycle is identified by applying the Bass diffusion model. Based on the results, we propose R&D strategies for decision-makers in the display industry, such as R&D investment, technology M&A, and monitoring strategy proposals.
