Last month, we wrote that according to reports, TCL will introduce printed OLED panels for use in the medical industry next year. It hasn't been long, and we have official confirmation that the Chinese giant has started production of such displays for general use. Will this be a game changer in the OLED market?
This information has been confirmed by the display production department TCL, namely CSOT at its annual DTC2024 conference held, of course, in China. Until now, printed OLED panels were to be used in a narrow medical industry, but the manufacturer justified production for a broader market. "Based on 11 years of continuous research and innovation, TCL CSOT's IJP OLED technology has achieved significant leaps and breakthroughs in technical specifications, establishing new industry standards." It must be admitted that research and testing started more than a decade ago may allow for the success of this solution.
The mass-produced panel presented by TCL is a 21.6-inch 4K display. It is typically used in the medical industry. In addition, a 27-inch OLED prototype was introduced, which may be an alternative to the panels from LG or Samsung used in monitors. The TCL display features RGB OLED pixels arranged next to each other, 4K resolution, a refresh rate of 120Hz, 250 nits of brightness across the screen, and 600 nits of peak brightness.
The problem may be the not very high brightness and refresh rate, where OLED monitors reach 480Hz in models from Sony or LG. An advantage that TCL boasts is a higher level of PPI compared to Retina displays with a value above 300 PPI. The use of RGB side-by-side is supposed to ensure the display of fonts without colored fringes, providing sharp and clear images. Importantly for EU ecological standards, OLED printing technology offers twice the material efficiency and a 50% reduction in light loss, resulting in higher light efficiency compared to traditional self-emissive displays. As a result, printed panels consume the same amount of energy as traditional ones while offering better image quality. TCL also assures higher durability of this type of solution.
The next novelty presented was, according to TCL CSOT, the world's first 14-inch IJP QD-EL 2.8K display. This new technology is based on quantum dots, and it was once known as true QLED and is also referred to as NanoLED and QD-LED. This display achieves over 85% coverage of BT.2020 colors and supports a variable refresh rate of 30-120 Hz.
