According to information gathered by the Korean media outlet The Elec, LG Display is developing, for the first time, OLED screens with five emitter layers, compared with the four layers of its most advanced Tandem WOLED panels to date, used for example in the LG G6 TV series and the Philips OLED911.
Brightness and durability up for future 2029 iMacs
This new technology is said to have been ordered by Apple for its very first [abc]Oled[/abc] iMacs scheduled for 2029, but it would also presumably be used in televisions. This fifth layer would offer greater brightness and better durability, in exchange for higher production costs.
The race for layers against Samsung Display's Penta Tandem
It is amusing to note that on one hand LG Display is trying to remove layers (from three to just two, cf. our news item LG Display dual-layer OLED panels: more affordable and less power-hungry, without loss of quality) to lower prices, and on the other to add them to improve quality. Note finally that five layers are nothing new, since Samsung Display has already been in the field since 2024 with Penta Tandem QD OLED.
