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 2017, only LG Display produces commercial OLED TV panels (China's BOE is initiating small-scale production). LG Electronics has several OLED TV models on the market - ranging in size from 55" to 77". LG's latest range of OLED TVs all support 4K (UHD) resolution and HDR. Reviews of OLED TVs are terrific, and most experts and consumers agree that OLED TVs are the best TVs ever produced - with virtually perfect image quality.

LG Display also supplies panels to other companies - including Panasonic, Sony, Grundig, Philips, Metz, Loewe, Skyworth, Changhong, Haier, Konka and others. The following table shows some of the prominent 2017 OLED TVs available in the US:

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.

UBI: The price gap between premium OLED and LCD TVs is almost gone

Nov 16, 2017

UBI Research is tracking the price of premium TV sold on Amazon.com in the US. As competition intensifies, the price gap between OLED and LCD TVs keeps getting lower - to the point where is not much difference between a high end Samsung QLED TV and LG's OLEDC7 OLED TVs.

LCD vs OLED TV price gap, (UBI Research, 2016-2017)

In December 2016, the price gap between a 65" LG OLED TV to a 65" Samsung SUHD TV was about $1,000. The price gap as of today is only about $300. The price gap for a 55" TV is even lower (around $200).

IHS: The production price gap between a 55" OLED TV and a 55" LCD is about 2.5 times

Nov 02, 2017

According to IHS, production costs of 55" 4K OLED TVs have declined 55% from the beginning of 2015 to Q2 2017. IHS estimates that it costs $582 for LGD to produce a 55" OLED panel, and the price will continue to drop to reach $242 in 2021.

55'' TV production cost, LCD-vs-OLED (2015-2017, IHS)

In early 2017 the cost of a 55" OLED TV is about 2.5 times the production cost of an equivalent 4K LCD TV panel. The price gap has narrowed as it was 4.3 times back in Q1 2015. The price in material cost is currently around 1.7 times - but other factors such as yields and depreciation increase LGD's production costs.

The Korea Government approves LG's Guangzhou OLED TV fab

Nov 01, 2017

In July 2017 LG Display announced that it has decided to build a 8.5-Gen (2200x2500) OLED line in Guangzhou, China, to make OLED TV panels. The Korean government hesitated whether to approve this plan, as it sees OLED as a strategic technology Korea' economy and this is the first time a Korean company plans to build an OLED fab outside of Korea.

According to a rather confusing report from Business Korea, it seems that the Korean Government committee decided to approve this plan, and LG is now free to start constructing its fab. The new fab, according to the initial plan at least, will be a joint-venture with the local government and LGD will hold a 70% share. The total cost for this fab will be KRW2.6 trillion ($2.3 billion USD).

Beyond lower-wages in China compared to Korea and the proximity to the huge Chinese market, LG is looking for a subsidy from the local government. LG Display's Guangzhou OLED line is supposed to be a joint-venture with the local government, where LGD will hold a 70% share.

DSCC: LGD will start mass producing top-emission OLED TV panels in 2019

Oct 27, 2017

LGD's current OLED TV panels use a bottom-emission architecture, but according to DSCC LGD is aiming to shift their production process to a top-emission design starting in 2019. LG currently has a pilot capacity of about 3,000 monthly top-emission substrates, and plans to start mass production (with over 10,000 monthly substrates) in 2019.

DSCC says that top-emission will be required for 65" 8K panels as a bottom-emission design will not be bright enough with such a high density. The shift to top-emission will increase the aperture ratio (=brightness) by around 10%.

DSCC: Ink-Jet printing could lead to 17% cost reduction in 55" OLED TV production

Oct 27, 2017

LG Display currently produces all its OLED TV panels using an evaporation (VTE) process. Market research company DSCC says that ink-jet printing is more efficient than current VTE processes as it will result in simpler displays (no need for color filters, for example, as used by LG's current WRGB displays). Ink-Jet printing will also enjoy lower depreciation costs and lower indirect expenses such as water and electricity.

DSCC estimates that an ink-jet printed 55" OLED TV panel will cost 17% less to produce compared to a VTE produced panel. An ink-jet printed panel will theoretically be significantly brighter (as the color filters absorb a large portion of the light), however solution-based OLED materials have traditionally lagged behind evaporation ones (Merck though says that the latest soluble materials are on-par with evaporation ones).
