Electronic paper is now closer than ever to changing the way we read, write, and study. This was hailed as a revolution so profound that some see it as second only to the invention of the printing press in the 15th century. In this study, four analytical methods, which included statistical analysis, technology decomposition, multistage technological evolution and growth potential analysis were used. Results showed that technological research on business has great potential for development and vast market, and it would be another 16 years before the limit could be reached for patents. A great deal of technology breakthrough has been achieved during 1992 and 2012. The four major countries for printed electronic paper development are Japan, USA, South Korea and China. However, China has a gap compared with other countries, as the key technology was held by large enterprises. The apparatus for printed electronic paper has been the major focus in China. The key point for research on printed electronic paper was focused on devices for presentation and light emission, and related semiconductor devices.
