TCL CSOT

TCL 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 both LCDs and OLED displays.

CSoT started developing OLED technologies back in 2012. In 2013 it was reported that CSOT will invest over $4 billion to build a 8.5-Gen Oxide-TFT LCD+OLED TV fab, but that did not materialize. In 2017 CSoT started to construct a 6-Gen LTPS flexible AMOLED production line in Wuhan, China, in a $5.08 billion investment. CSoT is now producing mobile AMOLED displays at that fab, and is developing high-end technologies, including LTPO, microlens arrays and polarizer-free OLEDs.

 

CSoT is very active with inkjet printing technologies, and is aiming to start mass production of OLED TV panels by 2024. Over the years the company presented impressive prototypes of printed panels.
