Company Profile
Zhengzhou Shenglong Information Technology Co., Ltd. (stock code:
831361), founded in 1998, is one of the earliest high-tech
enterprises in the world engaged in the design, production and
installation of LED display systems. The company adheres to the
concept of creative R&D design and is committed to the research
and development of technical products in the field of special
displays. It is an advocate and pioneer of new display technologies
in China.
Zhengzhou Shenglong Information Technology Co., Ltd. has a
technical team with doctoral supervisors, master supervisors and
senior engineers as the core. The technical staff have decades of
R&D experience. Many of them have participated in the
compilation of the textbook "Optoelectronic Display Technology and
Application" for Chinese universities. Team members have
participated in the construction of major projects such as the
Chinese government's countdown board for the return of Hong Kong to
the world-renowned Tiananmen Square, the largest screen in Asia,
and the Sydney Olympics.

successively passed ISO quality system, national standard quality
system, information security management system, intellectual
property management system, as well as US FCC certification, EU CE,
EU RoHS and other certifications; It has more than 70 patents and
software copyrights, and has established the "Henan Intelligent
Control and Aviation Information Technology Engineering Technology
Research Center" and "Zhengzhou Information Security Protection
Display System Engineering Technology Research Center" scientific
research platforms recognized by the government; Won nearly 100
qualifications and honors such as "Specialized and New", "Top 50
Electronic Information Enterprises", "National 100 Quality and
Integrity Enterprises", "National VR Industry Quality Leading
