OLED TV: Introduction and Industry News

Last updated on Sun 14/07/2024 - 14:42

What is an OLED TV?

OLED TVs use a display panel technology called OLED (Organic Light Emitting Diodes). Compared to LCDs, OLEDs offer an improved image quality, and are brighter, more efficient, and thinner. Simply put, OLED TVs deliver the best picture quality ever!

OLED TV technology

Each pixel in an OLED TV emits light on its own (in fact each pixel is made from 3 different OLEDs, red, green and blue). OLEDs are truly emissive devices with a simple design which gives them many advantages over current LCD technology:

  • High contrast: in OLEDs we have true blacks as when a pixel is off it does not emit any light. In LCDs, the backlighting is always on and so true blacks are impossible to achieve. Even when compared to the latest high-end mini-LED backlit LCDs, the contrast of OLEDs is superior.
  • High refresh rates: OLEDs can switch on and off much faster than LCDs.
  • Better power consumption: OLEDs only consume light on lit pixels - as opposed to LCDs who always need to use the backlighting. The power consumption of OLEDs depends on the image shown, but in most cases OLEDs will be more efficient than LCDs.
  • Flexibility: the simple design of OLEDs enables next-generation flexible, bendable, foldable and even rollable displays.

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

The leading OLED TV panel producer is LG Display - making panels ranging from 42-inch to 97-inch. These OLEDs offer the best image quality of all TVs on the market today. LGD is offering its OLED panels to many companies, including LG Electronics, Sony, Vizio and Panasonic.

In 2022 Samsung joined LGD and started to produce its own OLED TV variant, called QD-OLED (which is based on blue OLED emitters and quantum dots color conversion technology). QD-OLED panels offers a superb image quality, but Samsung's production capacity is smaller than LG's. 

Today close to 10 million OLED TVs ship every year, from many TV producers (including LG, Samsung, Sony, Panasonic, Philips and more), offering a wide range of OLED TV models. Click here for the latest OLED TVs on the market.

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.

Direct Emission vs WRGB / QD-OLED

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 used in Apple's latest iPhones, iPads and Watches). But direct-emission OLEDs are not available in TV sizes (not yet, anyway).

For its OLED TVs, however, LG Display uses 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 many years ago 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 compared to direct-emission TVs .

As we stated, Samsung's OLED TV architecture is based on blue OLED emitters and quantum-dots color conversion layers. In terms of performance, this architecture seems to be rather similar to LGD's WRGB panels.

OLED TVs - is there a path towards increased production capacity?

OLED TVs offer excellent image quality, outperforming LCDs with superb contrast, excellent and vivid color reproduction and fast refresh rates. In addition, OLEDs enable thin and efficient TVs. OLED TV production has been increasing up until a year ago, reaching a potential capacity of around 10 million units. This is impressive, but considering the entire global TV market that amounts to around 250 million units, OLEDs represent only around 2.5% of the total market (it is important to note that OLEDs tend to be produced in large sizes and carry a much higher average selling price compared to LCDs).

But OLED TV production capacity growth has declined in recent years. In this article we will shortly detail the history of OLED TV production, and look at potential paths towards increased penetration in the future. More details and into the future of OLED technologies and OLED TVs is included in the OLED Toolbox.

A bit of history: in 2013, both Samsung and LGD started producing OLED TV panels. Samsung chose the straightforward RGB side-by-side architecture, in which there are three sub-pixels, with red, green and blue OLED emitters. LG chose its own WRGB (or WOLED) architecture (the IP was acquired from Kodak in 2009) which uses four white OLED subpixels (made from yellow and blue OLED subpixels). Both companies released 55" FHD OLED TVs, priced at over $10,000 per unit. It soon became clear that Samsung's approach was not scalable, while LGD managed to enter mass production quickly and reduce prices dramatically within a few years to compete with the dominant LCD TV technology.

LG to launch screensaver ads on OLED TVs, do owners need to worry about lifetime and burn-in?

LG Electronics is going to add screensaver ads to its TVs, including its high-end OLED TV range. It seemed the company has already started testing this new feature, which shows full-screen ads, and the company will offer a way to turn the ads off, as it markets the new ad system a "feature".

LG Ad Solutions company announced the new "Native Screensaver Ads" feature, that "capitalizes on idle screen time, turning what may be perceived as a period of downtime into a valuable engagement opportunity".

Three former senior researchers from LG Display are accused of sealing OLED trade secrerts

According to reports from Korea, three former senior researchers at LG Display are accused of passing OLED trade secrets to a Chinese panel maker. The Seoul District Prosecutor office says that the there researchers took photos of designs at LGD's Guangzhou factor in 2021 and 2022, related to large-area WOLED panel production processes.

One of the suspects started working for a large China-based display company in 2021, and he allegedly colluded with a former LG Display employee to steal large-scale OLED panel mass production technology.

Study reveals OLED TVs promote healthier sleep patterns compared to LCD screens

Seoul's Kookmin University researchers concluded a clinical study to verify the impact of TV panels of sleep, measuring the levels of the sleep-inducing hormone melatonin in 40 adult men and women divided into groups watching the same content on either LCD or LG's WOLED TVs.

The researcher found that melatonin secretion fell 2.7% over two hours for the LCD group and it increased 8.1% in the OLED TV group. Melatonin rises in the evening to prepare the body for sleep, but the blue light emitted from displays disturbs the melatonin secretion as it confuses the body. As LCDs emit about twice as much blue light as OLEDs, it is not a surprise they have this effect on melatonin levels.
