OLED EX technology combines compounds of deuterium and custom algorithms to improve the stability and efficiency of the organic light-emitting diode, thus improving the overall performance of the screen and especially the brightness levels that can be increased by up to 30% compared to existing OLED panels.

In addition to the improved brightness levels, the use of EX technology also supposedly allows the screen to achieve “perfect black” and vivid colors, something these panels excel at. LG Display has also updated its designs using this technology, reducing the thickness of the bezel from the original 6mm OLED to 4mm.
