Transparent OLEDs: introduction and market status

Submitted by Ron Mertens on Sun, 02/10/2019 - 15:42

OLED technology enables thin, efficient and bright displays and lighting panels. OLEDs are currently used in many mobile devices, some TVs and lighting fixtures. OLED displays offer a better image quality compared to LCD or Plasma displays - and can also be made flexible and transparent.

Transparent OLED displays

Several companies develop transparent OLED (also referred to as T-OLED) technologies. While there's no inherent technology barrier towards transparent OLED displays, finding actual applications for such displays is not easy.

As of 2021, LG Display is producing 55-inch transparent OLED panels (used mostly in signage and commercial settings) while other companies produce small (around 1-2 inch in size) transparent PMOLED display. In April 2013 we posted a review of Futaba's 2" 160x128 transparent PMOLED panel - which could be an interesting read even if this specific display is no longer in production.

Transparent OLED Lighting

OLED technology can be used to make lighting panels - these are thin, area-lit and efficient lighting panels, that can be made transparent. Unlike displays, transparent OLED lighting panels have more immediate applications (embedded in windows, for example). In April 2012 we posted our hands-on review with a transparent Tabola OLED lighting panel sample. As the OLED lighting market in general is still at an early stage, we do not see actual adoption and production of transparent OLED lighting.

OTI says it is close to commercialization of its technology and materials, but the company is still some years before this will reach products. Towards the end of 2022 OTI started shipping its 2nd-gen ConducTorr Cathode Patterning Materials (CPM) to customers, but perhaps these were only sample shipments.

LGD says that the loss was due to weak demand for TV and IT displays, coupled with supply chain issues and the lockdowns in China. LGD says it plans to continue and reduce its LCD TV business, and to stop LCD production in Korea in 2023, earlier than expected before.
