From the perspective of market players, at present, the main global liquid lens enterprises include Corning, optotune, etc. These enterprises have higher technological maturity and earlier market layout, and occupy an absolutely leading position in the domestic and foreign markets.

 

Liquid lens is a lens made of one or more liquids, which can change the focal length by changing the curvature of the liquid. The liquid lens can realize automatic focusing and zoom, which helps to reduce the cost of optical lens and module, and can fully meet the needs of miniaturization of downstream devices and end products.

 

Liquid lenses are classified in many ways. According to the amount of liquid contained, the liquid lens can be divided into single liquid lens and double liquid lens. The single liquid lens realizes zoom based on the principle of physical suction, while the double liquid lens is mostly made based on the principle of electrowetting on the medium. According to its structure and working principle, liquid lens can be divided into liquid crystal liquid lens, liquid filled liquid lens, electrowetting liquid lens, liquid lens driven by dielectric elastomer, etc.

 

From the perspective of market players, at present, the main global liquid lens enterprises include Corning, optotune, etc. These enterprises have higher technological maturity and earlier market layout, and occupy an absolutely leading position in the domestic and foreign markets. The research of liquid lens in China started later than that in European and American developed countries, the technology accumulation is relatively weak, and the industrialization has not been realized. At present, the domestic liquid lens market is mainly occupied by Corning, optotune and other imported brands, and the main participants in the industry are imported brand agents. According to the Research Report on China's liquid lens Market Analysis and development prospects from 2021 to 2026 issued by xinsijie Industrial Research Center, China's liquid lens imports will exceed 100000 in 2020.

 

New thinking industry analysts said that in recent years, the research on liquid lens at home and abroad has continued to deepen, but some common problems have not been well solved, such as image distortion caused by unstable optical axis, high driving voltage and easy saturation of contact angle, which limits the expansion and application of liquid lens to a certain extent. At present, the practical application of liquid lens in the world is mainly concentrated in the industrial field. Representative downstream products include code scanners. With the progress of relevant technologies, the application of liquid lens has gradually penetrated into 3C electronics such as mobile phones.

 

With the rapid development of mobile Internet, Internet of things, artificial intelligence and other technologies, the application fields of optical lens are further enriched. Automatic driving, smart home, VR / AR equipment, UAV, 3D sensing and other fields emerge one after another, which not only injects new power into the development of optical lens industry, but also lays a foundation for the growth of liquid lens demand. In the future, with the development and application of 5g commercial and Internet of things, the market will have higher requirements for lens focusing speed and accuracy. Liquid lens is expected to be further popularized and applied in industries, entertainment and other fields, driving the rapid growth of its demand.
