CSOT shows a new wave of OLED screens – from 14 to 77 inches. During this year's Display Week trade show in Los Angeles, TCL CSOT presented new prototypes of OLED screens created using inkjet printing technology. At the booth, panels with diagonal sizes of 31, 65, and 77 inches were showcased, as well as a 14-inch 4K display designed for mobile devices and laptops.
The presented panels offer full coverage of the DCI-P3 color gamut, support for Dolby Vision, and refresh rates of up to 144 Hz. TCL also claims a contrast ratio of 1,000,000:1, and the response time should not exceed 0.1 ms. These parameters target the premium market, both for home entertainment and gaming.
Production technology without a metal mask – cheaper and more scalable!
The key element is the use of inkjet printing technology. Unlike traditional OLED production methods using a fine metal mask (FMM), inkjet printing allows for the precise application of organic layers without material waste and the need for expensive masks. This means potentially lower costs, especially for larger diagonals, which are currently exceptionally expensive to produce.
Importantly, CSOT is not just a one-off idea, as the company is already operating a plant in Guangzhou adapted for mass production of OLEDs using this method. This could mean that the first commercial products based on this technology will be seen sooner than we expected.
TCL also showcases a 115-inch Micro LED screen and a 162" miniLED 8K!
The new OLED panels are just part of the portfolio presented at Display Week. TCL demonstrated a 115-inch Micro LED screen, as well as a massive 162-inch miniLED 8K panel. Both projects confirm the company's ambitions to establish a presence not only in the consumer segment but also in the professional space, that is, in commercial environments and digital installations.
Micro LED, although still an expensive technology, offers exceptional image parameters: high brightness, no burn-in, deep blacks, and long lifespan. These characteristics make it a potential standard in premium applications – especially in the commercial sector and high-end home theater.
However, if you are looking for something available today, we recommend our current rankings of the best televisions from LG and Samsung – tested models that combine great quality with real availability.
Printed OLED in Practice – What's Next?
Although TCL CSOT's presentations remain prototype in nature, the message coming from the trade show is clear: OLED printing technology is maturing, and the Chinese manufacturer is at the forefront of its development. The question remains when panels will hit the consumer market – and whether they will be able to compete realistically with solutions from LG Display or Samsung Display.
However, looking at the pace of CSOT's progress and the ready infrastructure, one can assume that the next two years will be crucial for the fate of this technology. Inkjet printing in OLEDs is not just an alternative – it’s an opportunity to redefine the market in terms of pricing, sizes, and availability.
