According to the OLED-INFO service, TCL CSOT has developed breakthrough materials for inkjet printing of OLED panels that allow for the application of colour filters directly onto the encapsulation layer (COE architecture). This solution eliminates the need for a traditional polariser, paving the way for the production of cheaper and more efficient OLED screens.
COE: Thinner, Brighter, More Energy-Efficient
The use of COE architecture in the inkjet printing process allows for significant improvements in panel construction. According to data provided by OLED-info, TCL CSOT has already tested samples with a density of 326 PPI, which showed:
30% reduction in power consumption compared to panels with a polariser.
Light reflectance at just 6.41%, which translates to better readability in bright environments.
Higher material efficiency, which drastically reduces production costs in the long run (by as much as 15-20% compared to vacuum deposition methods).
Fight Against Dominant Korea
The new production method is set to be a direct response to WOLED (LG Display) and QD-OLED (Samsung Display) panels. TCL CSOT aims to first compete for the mid-size screen market, such as:
Premium tablets and laptops,
Monitors for gamers and professionals,
Or even medical displays
At the recent CES 2026 trade show, the company demonstrated that its ambitions reach further. Thanks to the flexibility of inkjet printing, these screens could soon be heading to car cockpits, offering unprecedented shapes.
Despite the status of a "development project," the rapid progress of TCL CSOT suggests that commercial products based on IJP-OLED may soon become a market reality.
