Competitors are not LCD and other display technologies - "China Electronics News": From the perspective of display technology, what is the current value and future development space of e-paper technology? In particular, how do you view the competitive relationship between e-paper and LCD and other display technologies?

Li Zhenghao: At present, the mainstream displays are mainly LCD and OLED, and Mini LED and Micro LED technologies have also emerged. It remains to be seen which technology will become the mainstream in the future. But from the perspective of electronic paper, electronic paper has never been to compete with display technologies such as LCD, OLED or Micro LED, but to develop as a technology to replace paper.

Therefore, in terms of resource investment in e-paper technology, it is mainly to make e-paper more like real paper in terms of vision and touch, and even flexible and foldable e-paper can be made in the future. Paper consumes a lot of electricity and natural resources in the production process, so it is not environmentally friendly; electronic paper has the characteristics of bistable and reflective type, which is less harmful to the eyes, and compared with LCD or OLED, whether it is The energy consumption of the manufacturing process and the power consumption of the product are much lower. Today, in the process of intelligent and digital transformation of electronic products, electronic paper is more suitable for application in IoT scenarios due to its power saving and eye-friendly features, which is different from the application scope of LCD and other technologies.

Of course, there are different subdivision technologies in the field of electronic paper, such as electrophoresis, electrowetting, cholesteric liquid crystal, etc., and each technology has its own characteristics and advantages. Yuantai's goal is to replace paper, so he is more optimistic about electrophoretic e-paper technology, hoping that e-paper can be applied to the surface of any object in the future and make it into a digital, non-luminous display product. In the future, when the full-color electronic paper display technology matures, it will be used more widely.

The market positioning of e-paper is different from that of LCD and OLED, so it will not be in a state of direct competition, but will open up some new applications that have not been used in the field of LCD or OLED before. In this context, cooperation between display technologies has become particularly important and is expected to achieve complementarity.
