China Star Optoelectronics Technology (CSOT, also called Shenzhen Huaxing Photoelectric Technology) is a China based display producer (owned by TCL, Century Science & Technology Investment and Samsung Display). The company is producing small and large LCD panels and is developing OLED technologies.
In March 2012 it was reported that the company plans to enter the AMOLED market. The original plan was to start production by the end of 2012 in a 4.5-Gen LTPS line, but that never materialized. In October 2012 AUO filed a law suit against two of its former executives that allegedly stole technologies (including AMOLED related ones) from the company and supplied it to CSOT.
Towards the end of 2013 it was reported that TCL and CSOT will invest 24.4 billion yuan (just over $4 billion) to build a new 8.5-Gen Oxide-TFT LCD+OLED TV fab in Shenzhen. In 2016 TCL revised its plan - and said that the new fab will use 11-Gen substrates and is to be built by 2019. In May 2018 TCL announced it has approved this plan, but now targets 2021 for actual production.
In April 2017 CSOT announced plans to construct a 6-Gen LTPS flexible AMOLED production line in Wuhan, China, in a $5.08 billion investment. In June 2017 CSoT started construction at the site.
Together with TianMa, in 2016 CSOT established a company called Guangdong Juhua Printing Display Technology to develop printing OLED TV technologies. Johua Printing is an "open innovation platform" guided by the Chinese government that collaborates with both industry and universities to drive the progress of China's display industry and the GUangdong Province specifically.
