Development judgment of the main display techniques based on the trends of Engineering System evolution
In order to assist R & D investment and science and technology projects management, the evolution trend of some main display techniques was evaluated.Based on the S-curve evolution trend, new display technology systems' development stage and direction were judged. And the relationship between R & D investment and market life was analyzed by using the patent quantity in different years.It is showed that liquid crystal and organic light-emitting diode display systems are in the mature and growing period, respectively, E-paper and laser display are in the transitional period, quantum dots and micro light-emitting diodes are in the infancy. A large number of patents indicates a large R & D investment and long market life of a technology. The lower the maturity of the technology system, the higher the invention level of R & D achievements. Therefore, the investment in basic research should focus on infancy, and the investment in R & D of common key technologies should focus on the transition period and the early growth period. The content and leading investors of R & D were put forward.
