TCL (CSoT) announced that the company has finalized the development of several new OLED technologies, which has been deployed at the company's production lines.
The first technology is LTPO, or Low-Temperature Polycrystalline Oxide, an OLED backplane technology developed originally by Apple. LTPO enables variable refresh rates, and TCL's technology can support a wide range of frequencies, from 1Hz to 144Hz.
The second technology is MPL, or Micro-Lens Panel. Using photolithography , TCL adds a micro lens array on top of the OLED panel, to increase light output. TCL says that its MPL panels offer an increase in power consumption (by increasing brightness) by 10-15%. Combined with LTPO, the technology can achieve power consumption improvement of about 30%.
The third technology is polarizer-free OLED (or PLP, Polarizer-Less Panel). TCL syas that its PLP panels reduce the thickness of the OLED panel by 20%, and improve light output by around 30%.
The fourth technology is low-frequency LTPS (called LTPS Plus). By changing the backplane design and optimizing the driving and the production process, TCL can now produce LTPS AMOLED displays with a 30Hz refresh rate, which will enable low power consumption, low-cost, low flicker and low-frequency displays.
TCL can now produce this range of new OLED displays at its T4 production line in Wuhan, with a monthly capacity of 6-Gen 15,000 substrates.
TCL is also moving forward with its inkjet printing process, and the company recently demonstrated a 65" 8K OLED panel, produced using an inkjet printing process. This display was co-developed by TCL's CSoT and JOLED.
Last year it was reported that TCL's CSoT is building a $6.8 billion 8.5-Gen inkjet printing line in Guangzhou (the T8 line), with production expected to begin in 2023.
