LG Display is expected to launch large OLED panels with micro lens array technology which will improve brightness and power consumption.

The South Korean display panel maker first unveiled a 77-inch 8K OLED panel with the technology and deuterium applied at SID 2022 in May this year.

Micro lens array (MLA) bends the light’s trajectory using lenses to increase luminance efficiency.

This allows light that would usually bounce inside the panel to head toward the viewer, increasing the overall brightness of the panel.

LG Display, last year, began applying deuterium on its OLED panels to increase their brightness from 800nit to over 1,000nit. The company brands these panels as OLED.EX.

Adding MLA technology to this will increase the brightness further and potentially prolong the panel’s life span as well.

LG Display faced problems when first applying MLA as it would result in “smudges” (also known as mura in Japanese, a word used outside of Japan as well in the sector) where the display surface looks uneven or nonuniform.

To resolve this, LG Display is planning to add an adhesive using micro beads to expand the light from the backlight evenly.

The adhesive will be supplied by Japan’s Sumitomo if the Korean firm decides to take this route.

OLED with MLA will not launch next year as LG Electronics and Sony, which purchases OLED panels from LG Display for their TVs, have no lineup with the technology, TheElec can confirm.
