SEL demonstrates a 15,000 nits direct-emission tandem OLED microdisplay

Japan's Semiconductor Energy Laboratory (SEL) demonstrated its latest OLED microdisplay technology at Displayweek 2024. The 1.5" 3840x2880 (3207 PPI) display achieves a brightness of 15,000 by using a tandem architecture and a direct-emission design. The OLED deposition was performed using photo-lithography. 

This is an impressive display, with very high brightness. It surpasses LGD's 10,000 nits microdisplay also shown at Displayweek, which uses a white-OLED with color filter design, and a microlens array. It matches eMagin's 15,000 nits microdisplay, demonstrated back in 2023 - which is a single stack device.

LG Display shows its latest OLED displays at Displayweek 2024

LG Display demonstrated its latest OLED display prototypes and commercial panels at Displayweek 2024. The company showed flexible panels, automotive displays, transparent OLED, gaming monitors, a 10k nit microdisplay and more.

So first up, LG Display shows its automotive Advanced-Thin-OLED (ATO) displays, which are produced on glass substrates and use a tandem structure. These OLEDs are lower in cost compared to LGD's flexible automotive p-OLED panels, but still enable low-weight and thin profile, and the excellent image quality of an OLED display. The smaller display was a 12.3" 2400x900 (209 PPI) 1,000 nits panel, while the other panel was larger at 17" 1920x2560 (188 PPI).

Japan Display to start producing eLeap laptop displays at its 6-Gen Mobara fab, ahead of schedule

In 2022, Japan Display (JDI) announced that it has developed a "historic breakthrough in display technology" - a new OLED deposition process which they refer to as eLEAP, that is said to be cost effective and can be used to create freeform OLEDs that are brighter, more efficient, and longer lasting compared to OLEDs produced using mask evaporation (FMM).

JDI is planning to establish a 8.7-Gen eLEAP fab in China, and it is also building a smaller-scale 6-Gen eLEAP production line in Mobara, Japan. The company announced that the 6-Gen Mobara fab is advancing ahead of schedule, and production of eLEAP panels will begin before the end of 2024. JDI developed 14" laptop panels that are three times brighter than other OLEDs (at 1,600 nits), and is also targeting smartwatches, smartphones and automotive displays. JDI is also looking into adopting a tandem structure, to increase brightness even further to 3,000 nits.

Reports suggest low yields at SDC's fab causes Apple to delay the launch of its first AMOLED tablets

In January 2024 we reported that Samsung Display and LG Display have started to produce AMOLED displays for Apple's future iPads, to be announced later this year. Earlier expectations were for Apple to order a total of 10 million iPad AMOLED displays in 2024 from both LGD and SDC, with LGD getting around 60% of the orders. 

Apple was aiming to launch the new OLED iPads this month, but have now reportedly delayed the release to May, as Samsung is suffering from low yields for the 11" AMOLED panels, mostly due to the tandem stack architecture.
