LG Display demonstrates a prototype WOLED display with a microlens MLA array

As we reported last week, LG Display is developing OLED TV panels that utilize a microlens array to increase the light output. LGD unveiled its first prototype display at SID Displayweek 2022.

LGD is showing a 77" 8K panel that features what the company refers to as Meta-lit Lens Array, or MLA technology. The MLA layer increases light output by more than 20%, and the panel achieves a brightness of 2,000 nits. LGD says that the viewing angles is also increased using the MLA technology.


To deposit the MLA layer, LG Display uses a deposition and patterning process that creates the convex lens shapes directly on the OLED panel. LG says t

The idea of adding a microLens layer is not new. Reports suggest that the Samsung Galaxy S21 Ultra AMOLED panel has such a structure. Last year Tianma demonstrated a smartphone panel with microLens array, saying that the power consumption savings are up to 15%. Seeya also has microLens technology in its OLED microdisplay roadmap.
