OLED is an emerging display technology that uses thin films of organic materials to make efficient, thin and high quality displays. OLED panels can made flexible, rollable and transparent. Korea's LG is at the forefront of OLED development and production - as the world's only OLED TV producer and a leading developer of flexible OLED and OLED lighting panels. LG's subsidiary LG Display is responsible for OLED R&D and panel production, while LG Electronics produces and markets OLED TVs.

LG OLED TVs

LG's 2018 OLED TV lineup include the flagship Wallpaper OLEDW8 (which attaches to the wall using magnets), the OLED-on-glass OLEDE8, the basic OLEDC8 and the entry level OLEDB8. The only TV that is shipping now is the 55" OLEDC8 which is priced at $2,500 (note: this is an affiliated link to Amazon).

As of 2018, the only company that produces produces commercial OLED TV panels is LG Display, and LG Electronics is the leading OLED TV producer - although LGD also supplies OLED panels to other companies including including Panasonic, Sony, Grundig, Philips, Metz, Loewe, Skyworth, Changhong, Haier, Konka and others.

Reviews of OLED TVs are terrific, and most experts and consumers agree that these OLED TVs are the best TVs ever produced - with virtually perfect image quality and beautiful form factors. LG is also developing next-generation OLED TV technologies, and has recently demonstrated a 65" rollable TV.

While the basic OLED TV design uses RGB OLED sub-pixels to create each 'pixel' (what is referred to as direct emission OLED, the design used in mobile OLED displays used in Samsung's and Apple's smartphones, for example), LG Display opted for a different OLED TV design. The so-called WRGB (or WOLED-CF) architecture uses four white OLED subpixels with color filters on top (hence W+RBG). The WRGB technology (developed by Kodak and now owned by LG Display) is much easier to produce and scale-up, even though it has some technical disadvantages - and it is the technology that enabled LG to be the first company to actually produce commercial OLED TV panels.



LG Flexible OLEDs for mobile devices

LG currently produces flexible OLEDs (branded as pOLEDs), for both wearable devices and smartphones. LG is the exclusive supplier of AMOLED displays for Apple's Watch smartwatch and it also supplies OLED displays for smartphones - such as the 6.4" 1440x3120 notch-type pOLED used in LG Electronics's V40 ThinQ, introduced in October 2018 and the 6" QHD+ display used by Sony in its Xperia XZ3 flagship.

LG Transparent OLEDs

LG are also working on transparent OLEDs. In 2014 LGD unveiled a 18" transparent OLED prototype, and later in 2016 LGD demonstrated transparent 55" FHD AMOLED display prototypes. These panels are not yet in production, but hopefully LG will start producing these eventually.

LG OLED Light

LG Display is developing and producing OLED lighting panels, and the company is one of the leaders in OLED lighting. The company produces several panels, including flexible OLED panels and high efficiency panels. In December 2017 LG started mass production at its new 5-Gen OLED lighting fab in Gumi, Korea.

The 5-Gen line has an initial capacity of 15,000 substrates per month - about 30 times the capacity of LG's previous 2-Gen line that had a monthly capacity of 4,000 substrates. LG hopes that the new line will enable it to produces OLED lighting panels at a much lower cost (initial estimates suggested a 95% cost reduction!) which it hopes will trigger the widespread adoption of OLED lighting globally.

Korea's supreme court ends years-long battle between LG and Samsung over OLED encapsulation trade secrets leak

The Korean Supreme court put an end to a years-long legal battle between LG Display and Samsung Display, saying that SDC's employees and a chief executive of one of LG's suppliers are not guilty in IP theft.

The supreme court upheld the original ruling and dismissed the appeal. The case revolved around LGD's face seal encapsulation technology for OLED displays. The main issue in the legal case was whether leaked LGD documents were trade secrets. The employees and executives were first found guilty, but at a higher court they were found innocent as it was decided that the information was already widely known in the industry.
