LGD's WOLED panels feature the highest color accuracy in the display industry, according to a new IEC standard

LG Display announced that the International Electrotechnical Commission (IEC) has adopted its “color perception difference measurement method” as an international standard. According to the new standard, LG Display’s large-sized OLED panels have high color accuracy, with a color perception difference of only about 10%, the lowest in the industry.

LG Display explains that in this context, differences in color perception refer to a phenomenon in which different viewers perceive the same color differently when it is shown on a display, resulting in color distortion. It is mainly caused by viewers’ visual characteristics, but the difference can be greater depending on the type of display. For example, the same white color can be perceived by different viewers to have either a blue or yellow tone.

Does it make sense for LG Display and Samsung Display to merge?

In this article, we examine the theoretical question of whether or not it makes sense for LG Display and Samsung Display to merge, into one company.

Note that we have no indications that such a merger is even considered by the two companies, but we feel this is a fascinating topic that should be explored, and is supported by several strong arguments.

We'll start with a short introduction to the two companies, then see why there are many reasons to pursue a merger, then explain the reasons against a possible merger, and finally detail the current financial situations of both companies.

Samsung Display and LG Display

Samsung Display Corporation (SDC) is a subsidiary of Samsung Electronics. SDC is a leader in OLED production, with a market share of over 40% in the small OLED display market (the second largest player, BOE, holds a market share of around 15%). SDC produces over 300 million AMOLED displays per year - supplying them to Apple's iPhones and tablets, Samsung Electronics Galaxy phones, and many more. The Company also produces larger-area QD-OLED panels for TVs and gaming monitors, and has a capacity of producing around a million TV panels per year. SDC no longer produces any LCDs. SDC does produce microLED displays (but on a very small scale, this is currently a strictly next-gen display technology), and the company develops OLED microdisplays (and also holds OLED microdisplay producer eMagin which it acquired in 2023 for $243 million).

LG Display's WOLED panels receive Eyesafe's Circadian Certification

LG Display announced that its entire lineup of OLED TV and monitor panels, from 27 to 97 inches (all of its WOLED panels), have become the world’s first displays to receive Eyesafe Circadian Certification. LG Display’s OLED TV and monitor panels achieved the highest circadian certification rating (CPF 50).

EyeSafe, a US-based company specializing in blue light mitigation solutions, says that LG's OLED panels are promoting eye health and better sleep, as the emit just 36% blue light, the lowest in the industry.

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.

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.
