What is an OLED TV?

An OLED TV screen uses a new display technology called OLED (Organic Light Emitting Diodes). OLED technology enables displays that are brighter, more efficient, thinner and feature better refresh rates and contrast than either LCD or Plasma displays. Simply put, OLED TVs deliver the best picture quality ever!

OLED TV technology

OLED displays are made by placing thin films of organic (carbon based) materials between two conductors. When electrical current is applied, light is emitted. OLED displays are emissive and unlike LCDs, do not require a backlight (unlike LCDs). OLED TV panels offers several advantages over LCDs:

  • Faster refresh rate, better contrast (true blacks) and better color reproduction
  • Better form factor - OLED enables much thinner panels
  • Better viewing angle - almost 180 degrees
  • Efficiency - in an OLED display, only the lit pixels draw power, unlike in an LCD.)
  • OLED panels can potentially be made flexible and/or transparent - think rollable TVs!

OLED TVs on the market - what can you buy today?

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's 2018 OLED TV lineup include the flagship Wallpaper OLEDW8 (which attaches to the wall using magnets), the high-end OLED-on-glass OLEDG8 and OLEDE8, the basic OLEDC8 and the entry level OLEDB8. All of these TVs are now shipping globally.

In August 2013, Samsung launched an OLED TV as well, the KN55S9C, that used Samsung's own OLED TV panels. Samsung stopped producing and marketing the S9C OLED TVs soon afterwards and is currently focused on quantum-dot enhanced LCDs (and perhaps Micro-LED will be Samsung's future TV display technology of choice).

Direct Emission vs WRGB

The most straightforward OLED architecture uses 3 color OLED sub-pixels (Red, Green and Blue) to create each 'pixel'. This is referred to as a direct emission OLED, and is the design used in mobile OLED displays (for example those in Samsung's Galaxy S8 and Apple's iPhone X.

For its OLED TVs, however, LG Display is using a different architecture, called WRGB (or WOLED-CF) which uses four white OLED subpixels (each created by using both blue and yellow OLED emitters) with color filters on top (RBG and W). The WRGB technology (developed by Kodak and now owned by LG Display) was found to be easier to scale-up for large-area OLED production, although it suffers from lower efficiency and more complicated design.

Rollable and transparent OLED televisions?

Like we said before, OLEDs can be made flexible, or transparent. Both LG and Samsung demonstrated large 55" transparent and mirror OLED prototypes, and LGD already demonstrated 77" rollable and transparent OLED panels, which it plans to commercialize by 2020. These kinds of technologies are exciting - and while it will be some years before they reach the market, they could eventually redefine the TV of the future.

DSCC: the OLED market will grow 19% in 2019 to reach $31 billion in revenues

DSCC estimates that the AMOLED market will grow 19% in 2019 to reach $31 billion, up from $26.5 billion in 2018. OLED revenues will continue to grow and reach $48.8 billion in 2022 (a CAGR of 16%).

OLED panel revenue by type, (2016-2022, DSCC)

Look at OLED unit shipments and area production, 2019 will see a 22% growth in unit shipments to 610 million panels and a 35% growth in area to 9 million square meters. Area shipments will grow faster than revenues as OLED selling prices will continue to decline - and as OLED TVs take up a larger share of the OLED market.

Here are JOLED's new OLED display prototypes

Japan-based printed OLED developer JOLED demonstrated several new OLED displays at Finetech Japan last week. We already posted on these new OLEDs, and now we have photos of the new panels.

More details emerge on Samsung's QD-OLED TV Plans

Samsung Display is developing hybrid QD-OLED TV technology, and according to estimates, the company aims to begin trial production in 2019. It seems that Samsung is managing to overcome the technical challenges and the company is preparing to start production of such QD-OLED TVs in 2019.

Last month Digitimes updated about Samsung's plans to start installing equipment by the end of 2018 and begin trial production in H2 2019. Digitimes now posted another article, revealing more details on Samsung's plans.

JOLED to show new printed OLED monitors and TV prototypes at Finetech Japan

Last month Japan-based printed OLED developer JOLED announced that it will demonstrate new OLED prototypes (including a 55" printed OLED TV) at Finetech Japan, which starts tomorrow (December 5). Today JOLED detailed the new panels it will have on display at the trade show.

So first we have two automotive displays - a 12.3" HD OLED and a 12.2" flexible (curved ) Full-HD OLED. JOLED's latest investors, Denso and Toyoto Tsusho, are both helping the company with its entry into the automotive display market.

CSoT breaks ground on its upcoming T7 fab, which includes a printed OLED TV line

China-based display maker CSoT held a ceremony yesterday as it started construction on its upcoming T7 large-area display production fab. The T7 fab, which has a total cost of around 42.7 billion Yuan ($6.15 billion USD), will produce both LCD and OLED display.

Total capacity in the T7 line will be 105,000 monthly substrates (according to our information, the OLED capacity will be 20,000 monthly substartes). The T7 OLED line will use IGZO backplanes and inkjet printing deposition. CSoT's plan is to start production by the end of 2020 - with real mass production starting in 2021.

BOE demonstrates its first ink-jet printed OLED TV prototype

BOE is hosting its Global Innovation Partner Conference 2018 (BOE IPC-2018, which invited experts from all over the world to see BOE's latest technology and future trends.

During the event, BOE unveiled an ink-jet printed 55" UHD OLED TV prototype. This is the first time that BOE demonstrated an ink-jet printed TV (in May 2018 BOE unveiled 5.5" FHD flexible AMOLED which was also produced using a printing process).

Panasonic demonstrates a transparent OLED TV prototype in Shanghai

Panasonic is demonstrating a new transparent OLED TV "Smart Glass" prototype at the China International Import Expo tradeshow in Shanghai. We do not have any specification of this panel.

In September 2017 Panasonic demonstrated a 55" 4K transparent OLED, this could be the same display but we are not sure. We do not know who's the producer of the panel itself, but it is likely to be LG Display.

JOLED to demonstrate a 55" ink-jet printed OLED TV next month

Japan-based printed OLED developer JOLED announced that it will demonstrate a 55" 4K printed OLED TV at Finetech Japan 2018 (December 5-7 2018). JOLED will also introduce its proprietary printed OLED manufacturing technology. A few weeks ago JOLED announced that it has signed an agreement to develop, manufacture, and sell printing equipment together with Panasonic and Screen Finetech.

This is the first time JOLED will show a 55" OLED prototype (in July 2018 the company did include TVs in its future roadmap). JOLED tells us that it has no plans to produce large size OLEDs at this stage - and this TV is on display just to demonstrate JOLED's printing technology.

LG to bring a rollable OLED TV and a foldable OLED phone to CES 2019

LG Electronics demonstrated its 65" rollable OLED TV prototype in 2018, showing how such a display can be used to create a TV that rolls into its base.

Engadget says that LG has plans to showcase a rollable TV again in CES 2019 (January 9-11). Engadget says that according to its information the rollable TV will take "center stage" in next year's event - which may point to the fact that LG is close to commercializing such a TV. In 2017 LGD did say it plans to bring rollable OLED TVs to market by 2020.

LG - we sold over 3 million OLED TVs since launching the first one in 2013

LG Electronics said that it has sold over 3 million OLED TVs, since launching its first one in 2013 - in September 2018 it has shipped over 3.2 millionth units, in fact.

LG Display is increasing its production capacity quickly, and so LG Electronics can increase its TV shipments (although today there are over a dozen other companies that use LGD's OLED TV panels, including Sony, Philips, Panasonic and Toshiba). In 2018 alone LGD expects to sell a total of 2.9 million OLED TV panels (up from 1.7 million in 2017).
