A couple of days back, we reported that LG announced its new OLEX EX technology, which aimed to improve brightness by as much as 30 percent compared to current OLED provided by the Korean giant’s competitors. An increase in overall brightness could allow OLEX EX to be directly comparable to mini-LED, which can hit 2000 nits of brightness and higher. More importantly, it can overcome one limitation that may entice the likes of Apple to use it in future products. Let us discuss.

LG stated that OLED EX’s 30 percent brightness increase is due to the use of deuterium compounds to allow the light-emitting diodes to emit stronger light. Unlike mini-LED, any product that takes advantage of OLEX EX will not suffer from the blooming effect, which can be noticed on Apple’s 12.9-inch M1 iPad Pro. Later, a display analyst Ross Young commented that the reason this blooming effect shows up on Apple’s flagship tablet is due to the lack of dimming zones, and if OLED was used in its place, this small but noticeable issue would not materialize.
