TCL CSOT has unveiled a new generation of IJP OLED panel, that is, an OLED manufactured using inkjet printing. The 27-inch panel offers 4K resolution, a 120 Hz refresh rate and, most interestingly, a claimed brightness of as much as 500 nits across the entire screen.
500 nits across the full screen
It's an important distinction, because modern OLEDs can reach very high brightness in small patches of the image, but with a full white screen they usually perform significantly worse. PC Gamer notes that current QD-OLED and WOLED solutions achieve roughly 300–335 nits of full-screen brightness. The new TCL CSOT panel should therefore represent a clear step forward. The manufacturer has also used the classic Real Stripe RGB subpixel layout, which may improve text legibility and reduce coloured fringing typical of some current OLED panels.
OLED printed like ink
IJP OLED also differs in its production method. Instead of depositing organic materials in vacuum through masks, TCL CSOT uses a technology similar to inkjet printing, in which the OLED material is applied directly onto the substrate. The company is increasingly developing this technology. In August, MSI already showed a 27-inch 4K 120 Hz monitor with a TCL CSOT IJP OLED panel and, as we mentioned in another news item, TCL is also building a Gen 8.6 production line intended specifically to scale this technology.
No release date yet
The panel shown is 27-inch, 4K and 120 Hz, but TCL CSOT has not yet given a date for when a specific monitor with this 500-nit version will go on sale. It's also unclear when the technology will be offered in other sizes. If the manufacturer's claims are confirmed in final monitors, IJP OLED could become a real competitor to QD-OLED and WOLED, particularly where high brightness across large, bright image areas matters.
