TCL CSOT showcases its portfolio of inkjet-printed (IJP) display technologies, including a People's Choice Award-winning 27-inch 4K monitor based on Quantum Dot Electroluminescence (QDEL). This next-generation QDEL display is presented alongside a 27-inch 4K inkjet-printed OLED monitor, which is scheduled for mass production this year. The IJP process is utilized for RGB materials across various layers, aiming to reduce manufacturing costs.

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

A direct comparison of the 27-inch 4K monitors reveals key differences. The QDEL prototype achieves 500 nits of brightness and covers 85% of the BT.2020 color gamut, offering superior color performance. The IJP OLED reaches 400 nits and covers 100% of DCI-P3. The QDEL technology is positioned as a future product, with a development timeline of two to three years for market readiness. Both IJP technologies are highlighted for their eye-care benefits, reducing harmful blue light by approximately 20%.
The demonstration also includes several other applications of inkjet-printed OLED technology. A notable product is the first R-shaped IJP OLED notebook display with a 2.8K resolution and a 3mm R-shape curvature. For gaming, TCL CSOT presents an IJP OLED notebook panel with a 240Hz refresh rate. These displays are built on an LTPS (Low-Temperature Polycrystalline Silicon) backplane.
Further expanding the lineup, TCL CSOT displays a 27-inch monitor that utilizes an oxide backplane instead of LTPS. This oxide array technology enables a high refresh rate of 240Hz while also offering a lower cost structure. A 2K tablet display is also shown, emphasizing the eye-care advantages of the IJP OLED technology. The versatility of the panels is demonstrated through a foldable and portable monitor that can expand to 28 inches or be used as a 16-inch display when folded.
Beyond consumer electronics, the same flexible inkjet-printed panel technology is adapted for automotive applications, shown in a curved display configuration. The exhibit also features a stretchable display concept, illustrating the potential for dynamic screen sizes in future devices. These prototypes collectively represent TCL CSOT's strategic focus on advancing inkjet printing as a core manufacturing process for next-generation OLED and QDEL displays.
