In May 2022 we reported that LG Display is looking into adopting a microLens array in its large OLED TV panel architecture. The microlens layer could boost brightness by up to 20%, which will also increase efficiency (if brightness is kept as before). According to a new report from Korea, LGD is progressing in its project and estimates that the first MLA (Micro Lens Array) OLED panels will enter production in 2024.

The original report in May stated that LGD could actually begin producing MLA OLEDs as early as in 2022 - but it seems as this was overly optimistic. Earlier this year, LGD demonstrated a 77" 8K MLA WOLED panel.
LGD will apply the technology to its OLED.EX panels, so brightness could reach up to 1,200 nits. LGD considers this technology as it faces competition in large-area OLED production, from Samsung's QD-OLED panels, for the first time.
