SID 2025, TCL exhibits inkjet OLEDs from 6.5 inches to 65 inches… Will mass production shake up the display market?
At the SID 2025 Display Week, TCL showcased various sizes of inkjet OLED products. The inkjet method is considered to be a technology that is advantageous in reducing material costs compared to the vacuum deposition method due to its high utilization efficiency of luminescent materials. TCL officially announced the mass production of a 21.6-inch 4K inkjet OLED professional display in November 2024, and is currently considering investment for mass production.
At this exhibition, TCL showcased a 6.5-inch inkjet OLED display for smartphones, which provides a high resolution of 360ppi based on real stripe, which is equivalent to approximately 460ppi based on pentile. In addition, a variety of product lines were exhibited, including a 14-inch oxide TFT-based OLED notebook panel with a 2.8K resolution (243ppi), a 27-inch OLED monitor with 4K 120Hz specifications, and a 65-inch OLED TV display with 33 million pixels and 8K 120Hz.

The 65-inch product maintains 99% of the DCI-P3 color gamut even in low-gradation, and has applied technology that doubles the utilization of light-emitting materials and reduces blue light by 50%. This is evaluated as a significant technological breakthrough in the large-scale and commercialization of inkjet OLED.

With a full lineup from 6.5 inches to 65 inches, TCL has shown confidence that inkjet OLED technology can be applied to all product lines from mobile to TV. Up to now, Chinese OLED panel manufacturers have focused on production based on technologies first verified by advanced companies, but inkjet OLED is the first technology that China has led in mass production. The success of this technology can be an opportunity for Chinese panel manufacturers to leap forward in both technology and production.
However, OLED using vacuum deposition method is continuously improving brightness and lifespan through tandem IT OLED structure or multi-stack TV OLED structure, and inkjet OLED still has the task of not only securing productivity but also reducing this performance gap.
