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.

Digitimes: Samsung and LG aim to reduce their reliance on foreign organic material producers

Mar 22, 2017

Digitimes Researcher states that currently Samsung Display and LG Display both rely on imported organic materials used in OLED production, but the two Korean makers aim to decrease this reliance. Both companies are buying stakes in companies outside of Korea (for example Samsung's Novaled acquisition and Sun Fine Chem investment) in order to obtain patents and move production in house, mostly at LG Chem and Samsung SDI.

The polyimide used as a substrate in flexible OLEDs, for example, is produced by Japanese Ube Industries - and used by both LG and samsung. Several organic materials used in the OLED stack are produced by Universal Display (PHOLED emitters), Idemitsu Kosan, Dow Chemical and Merck. Both companies use glass mostly from Corning and high-temperature thin film for the back-end processing from 3M.

How does LG's Wallpaper OLEDW7 compare to last year's high-end OLEDs?

Mar 14, 2017

LG started shipping the 65" Signature Wallpaper OLED W in the US recently. The price of LG's flagship TV is $7,999 (the 77" will cost $19,999 and will launch later this year). Value Electronics in New York now has one such on display, and the company sent us the following photos and video showing the display in action.

We also discussed the installation and quality of the new TV. Robert Zohn from VE says that the TV wall mounts very easily and the connection is done via the low-voltage control cable which is placed inside the wall. The cable is then connected to the I/O box (which LG calls the AIO box). This creates the beautiful look as the TV has no visible connections and is virtually attached on the wall with a very thin profile.

DSCC sees 1.2 billion mobile AMOLED displays produced in 2021, SDC's market share to drop to 63%

Mar 10, 2017

Display Supply Chain Consultants (DSCC) released some very interesting information regarding the mobile OLED market from its recent OLED market report by Yoshio Tamura and Ross Young. DSCC expects mobile AMOLED demand to grow from almost 400 million panels in 2016 to almost 1.2 billion in 2021.

AMOLED shipments by smartphone brand (2016-2021, DSCC)

Samsung Electronics, who's already using AMOLED displays in almost 80% of its smartphones will not increase its AMOLED orders by a lot, but shipments will grow dramatically to other players led by Apple, Huawei and Oppo.

The OLEDC7 is one of LG's basic models in its 2017 OLED TV lineup, an update to the OLEDC6 series from 2016. Interestingly, the C7 uses a flat panel (unlike the curved one in the C6). These OLED TVs (55" or 65") feature 4K resolution, HDR support (four different standards), WebOS 3.5 and Dolby Atmos sound.

LG reveals an AMOLED VR headset prototype

Mar 02, 2017

LG announced that it is developing a new VR headset that is powered by Valve's StreamVR tracking. LG demonstrated a prototype at the Game Developers Conference and revealed the specification of the device.

LG's VR headset uses dual 3.64" 1440x1280 (529 PPI) 90Hz OLED displays, produced by LG Display (which means that these are probably flexible OLEDs produced on plastic substrates). The headset provides a 110-degrees field of view, and LG is ready to make development kits later this month and will ship them to select partners.

LGD progresses with its P10 OLED fab, considering building a Gen-10 TV line

Feb 07, 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. The P10 will produce both mid-sized flexible OLED and large-sized OLED TV panels. Production was planned for the first half of 2018.
