After more than 10 years of development, the company based on data storage business, and through continuous horizontal layout of the new generation of information technology industry actively, it has expanded its business to the field of human-computer interaction touch with data collection as the core application direction and the field of photoelectric communication with data transmission as the core application direction. At present, the company has completed the development of its own touch control chip, among the field of human-computer touch control interaction. On this basis, the company form the touch control module for different application scenarios of integrated solutions, and achieve small-scale trial produced; In June 2020, the company established a wholly-owned R&D tam and the subsidiary named Shenzhen Techwinsemi Optoelectronic Company Limited, focusing on the development and industrial application of high-speed optical communication chips. The chip is designed to meet the rapidly growing industrial application requirements of the new generation of information technology products such as intelligent terminals and self-driving technology. The VCSEL optical chip project, which has been approved by Shenzhen 2020 and 2021 Major Projects, is currently in the stage of industrial application exploration.
