TCL CSOT Mass Produces 27-Inch 4K IJP OLED Panel for Monitors

TCL CSOT has shifted its OLED manufacturing strategy by beginning mass production of a new 27-inch 4K 120Hz RGB stripe panel. This move matters because the company uses Ink-Jet Printing (IJP) technology to lower costs and increase speed compared to traditional methods. Buyers looking for high-refresh-rate monitors may see more affordable options as these manufacturing efficiencies scale. The panel marks a departure from the company's previous reliance on LG Display for large-size OLED supplies.

New ink-jet printing method lowers manufacturing costs by over 20 percent

The specific product is a 27-inch display panel designed for IT devices like monitors, laptops, and tablets. It features a 4K resolution and a 120Hz refresh rate to support gaming and high-fidelity content. The panel achieves 300 nits of brightness and covers 99% of the DCI-P3 color gamut. This configuration targets users who need accurate color reproduction and smooth motion handling in non-television applications.

Panel Specifications

• Panel Size: 27 inches
• Resolution: 4K
• Refresh Rate: 120Hz
• Brightness: 300 nits
• Color Gamut: 99% DCI-P3

TCL CSOT developed this panel using Ink-Jet Printing (IJP) technology on its 5.5th Gen production line. The company states that IJP manufacturing reduces costs by over 20% compared to traditional vacuum evaporation. Production speed also increases by approximately 30% with this new method. The company claims the panel has passed internal verification and officially entered mass production.

The company is investing 1.5 billion RMB to triple capacity at its Wuhan 5.5th Gen line. This expansion serves as a transition before an 8.6th Gen line opens in Guangzhou, which targets 2027. Initial production focuses on IT devices to avoid the OLED burn-in issues prevalent in TVs. We looked at TCL CSOT Completes T8 Factory in our earlier coverage of their inkjet OLED progress.

End-product availability will likely lag behind the panel mass production start. The source notes that terminal product launch requires additional development time. The company is currently focusing on monitors and other IT hardware rather than immediate consumer TV releases.
