Seoul's Kookmin University researchers concluded a clinical study to verify the impact of TV panels of sleep, measuring the levels of the sleep-inducing hormone melatonin in 40 adult men and women divided into groups watching the same content on either LCD or LG's WOLED TVs.

The researcher found that melatonin secretion fell 2.7% over two hours for the LCD group and it increased 8.1% in the OLED TV group. Melatonin rises in the evening to prepare the body for sleep, but the blue light emitted from displays disturbs the melatonin secretion as it confuses the body. As LCDs emit about twice as much blue light as OLEDs, it is not a surprise they have this effect on melatonin levels.

Xiaomi announced four new devices, all with high-end AMOLED displays. First up we have the Mix Fold 4, a foldable smartphone that has a 7.98" 120Hz 3000 nits 2224x2488 foldable LTPO AMOLED display, and a second 6.56" 120Hz 3000 nits 1080x2520 LTPO external AMOLED display.

According to a new report by Business Korea, LG Display is finalizing the development of its 3rd-gen tandem-stack automotive OLED technology, and aims to start mass producing these panels by 2026. LGD believes the new panels will improve the brightness and efficiency of its OLEDs by 20% (compared to its current 2nd-gen tandem OLEDs).

LG Display believes it is leading the industry with its tandem OLED technology (and we tend to agree) and it hopes to accelerate its technology development to widen its lead. LG Display is enjoying a lead in the automotive display market with its OLED solutions and has already achieved design wins with many companies, including Genesis, Mercedes-Benz, Cadillac and GM.
