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 is the world's clear leader in OLED TV technologies. LG Display is the only company that produces commercial panels (although China's BOE is also entering production), and LG Electronics has several OLED TV models on the market - ranging in size from 55" to 77". Some of these are flat, and some are curved, and all the latest models support 4K (UHD) resolution and HDR. Reviews of LG's OLED TVs are great, and most experts say that these are the best TVs ever produced - with virtually perfect image quality. Following is a table of LG's 2016 models (LG's 2017 OLEDTV models are just entering the market now as well)

In early 2017 LG launched updated 2017 models, and the company's new flag ship TV is the Wallpaper Signature OLEDW7. These extremely thin TVs (2.57 mm all the way) attach to the wall using magnets. LG Display also supplies panels to other companies - including Panasonic, Sony, Grundig, Philips, Metz, Loewe, Skyworth, Changhong, Haier, Konka and KTC.

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 such as those in Samsung Galaxy S7 Edge and Apple's Watch), 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 plastic-based OLEDs in its Gen-4.5 fab, with a monthly capacity of 14,000 substrates (more than double its capacity in the beginning of 2014). LG Display's flexible AMOLEDs were used in LG's mobile phones (the G Flex 2) and are currently used in wearable devices (such as the Wear 2.0 Watch Sport) and in Apple's Watch and Watch Series 2.



LG's flexible OLED capacity is quite limited at this stage, but the company is set to dramatically increase its production capacity. With 3 flexible OLED fabs already underway. The first one will be the the E5 6-Gen (1500x1850 mm) $900 million line that is scheduled to begin mass production in the first half of 2017.

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 Lighting

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 the world's largest OLEDs (at 320x320 mm) and the world's first flexible OLEDs (on a glass substrate).

LG's current OLED lighting production capacity is limited, but the company is constructing a Gen-5 OLED lighting fab that will enter production in early 2017. The new fab will enable LG to increase production volume and cut prices dramatically.

LG orders two 6-Gen flexible OLED deposition systems from Canon Tokki

Jun 23, 2017

Japan-based Canon Tokki is considered the world's leader in vacuum evaporation equipment, and the company has a large backlog - reportedly it had to decline orders from several OLED makers as all of its capacity was taken up mostly by Samsung Display and BOE.

LGD confirms that its P10 plant in Paju will be exclusively used to make OLED displays

Jun 22, 2017

Towards the end of 2015 LG Display announced that it plans to build a new OLED fab (P10) in Paju in a $8.7 billion investment to produce both mid-sized flexible OLED and large-sized OLED TV panels. In May 2017 it was reported that LG decided to produce LCD panels rather than OLED panels in its upcoming fab.

According to Business Korea, LGD has confirmed that the P10 plant will indeed be used to produce only OLED displays - and will vote on this decision next week. The P10 fab will be used to make OLED TV panels in addition to small and medium sized flexible OLEDs. LGD has yet to decide exactly how to split the production capacity between large-area and small-area displays.

Google and a leading OLED maker are developing a next-gen OLED VR display

May 30, 2017

Google's VR vice president, Clay Bavor, revealed that Google has partnered with "one of the leading OLED makers" on a secret project to develop a high-end VR display. The OLED display will support a resolution of 20 million pixels per eye.

This is a very high resolution - a 4K display has 8.3 million pixels, so it means 2.5X the number of pixels in a 4K display. It terms of display density (which depends on the panel size of course, which we assume to be around 3.5"), this could be around 1,800 PPI.
