Paweł KoperAccording to OLED-INFO, TCL CSOT has developed breakthrough materials for inkjet printing OLED panels, which allows for the application of color filters directly on the encapsulation layer (COE architecture). This solution eliminates the need for a traditional polarizer, opening the way for the production of cheaper and more efficient OLED screens.
COE: Thinner, Brighter, More Economical
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:
Power consumption reduction of 30% compared to panels with a polarizer.
Light reflectance coefficient of just 6.41%, which translates into better readability in bright environments.
Higher material efficiency, which in the long run drastically reduces production costs (by even 15-20% compared to vacuum deposition methods).
Fight Against Dominant Korea
The new production method is expected to be a direct response to WOLED (LG Display) and QD-OLED (Samsung Display) panels. TCL CSOT intends to primarily compete for the market of medium-sized screens, such as:
Premium tablets and laptops,
Monitors for gamers and professionals,
Or even medical displays
However, during 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 make their way into car cockpits, offering previously unseen shapes.
Despite the status of "development project," the rapid progress of TCL CSOT suggests that commercial products based on IJP-OLED may soon become a market reality.
