OLED (Organic Light Emitting Diode) technology offers bright, efficient and fast displays, outperforming LCD display. OLEDs deliver the best picture quality ever and are used in many devices, from smartwatches through smartphones and tablets to TVs and more. 

OLEDs are also used to enable high-end monitors that offer excellent contrast, image quality, colors and new form factors.  This article will explain the benefits, the current status and the future of OLED monitors.

OLED monitors vs LCD monitors

  • OLED provide a better image quality with a much higher contrast (true blacks), wide color gamut, better viewing angles and a much faster refresh rate (great for gaming!)
  • OLED panels are much thinner and lighter compared to LCD panels
  • OLED monitors consume less power - as only lit pixels draw energy on OLED displays
  • An OLED monitor can be flexible, bendable, rollable - and transparent

OLED monitors and the burn-in challenge?

Of course OLED technology is not perfect. One of the major drawbacks of an OLED display is image retention / burn-in. In an OLED display each pixel is driven independently and each pixel ages differently - and as brightness is reduced with use (the lifetime of OLED materials is limited), we have burn-in problems.

For mobile phones and TVs this is less of a problem - but in a computer user interface many UI elements are quite fixed (toolbars, icons, etc) which means that burn-in is a real problem. There are some technologies to handle this problem - for example by measurement and compensation, or by adopting a tandem architecture to increase the lifetime. In addition user-interface designers can design a user interface that will be more suited for OLED displays.

OLED monitors on the market

OLED technology is very popular in smartphones, wearables and TVs - and in recent years OLED monitors has entered the market as display makers now target this market, starting with high-end models aimed towards gaming and content creation.

Display makers LG Display, Samsung Display and others target premium applications and mostly produce OLED panels in the range of 27-inch to 42-inch. One example of an OLED monitor is the ViewSonic VX2776-2K-OLED, based on a 26.5" 1000 nits (HDR) 2560x1440 240Hz 0.03 ms G2G VRR WOLED display (made by LGD).

Asus has several OLED monitors. The PG32UCDM and PG34WCDM are two gaming monitors, each based on a different OLED panel technology. The PG32UCDM uses a 32" 4K (3840x2160, 16:9) 240Hz VRR 1000 nits (HDR peak) QD-OLED panel, produced by Samsung Display. The PG34WCDM monitor, on the other hand is based on a 34" 3440x1440 (21:9) 240Hz VRR 1300 nits (HDR peak) MLA (microlens) WOLED curved (800R) panel, produced by LG Display.

Samsung has its own high-end OLED monitor, the Odyssey OLED G95SC. This is an ultra-wide gaming monitor based on a 49-inch 5120x1440 resolution, 240Hz, 1800R curved QD-OLED panel. The G95SC is now shipping, for around $2,000.  LG also offers OLED monitors, including the UltraGear 27GR95QE-B a gaming monitor with a 27" 2560x1440 240Hz 0.3ms (GtG) response time OLED display. The 27" UltraGear OLED monitor is now shipping for around $850.

LG Display said to be progressing with its 8.6-Gen IT AMOLED line plans, to announce its plans in H2 2024

According to recent rumors, LG Display has decided to go ahead and build its 8.6-Gen (2250 x 2600 mm) IT AMOLED line, in Paju, Korea (at its P10 hub, which was originally planned for OLED TV production). The company recently started to conduct discussions with equipment makers for supply agreements.

LGD P10 OLED fab, Paju Korea (March 2019)

LG Display's plan is to officially announce its 8.6-Gen production line plans in the second half of the year, and start ordering equipment. It is likely that the capacity of the fab will be between 7,500 to 15,000 monthly substrates. LG will be using its P10 building and existing equipment (backplane deposition) to reduce the costs of the 8.6-Gen line. This will mean that there will be delays to LG's WOLED TV panel capacity expansion plans.

Omdia sees a rebound in the display production equipment market

Market research firm Omdia says that display production equipment sales will rebound in 2024 and reach $7.7 billion (154% over 2023), and will grow slowly in the near future, mainly driven by 8.6-Gen OLED production lines (used to make IT displays).

Omdia says that the new 8.6-Gen OLED fab require novel technologies, which results in high equipment costs. In 2024, 32% of all spending ($2.4 billion) will be for Samsung's A6 line, a large investment for a 15,000 monthly subtrates fab. BOE's investment in its upcoming B16 flexible 8.6-Gen line will be even higher - by 18% due to the backplane choice (LTPO over Samsung's oxide-TFT A6).

Rtings.com posts the results of its 10-month OLED and LCD display longevity tests

RTINGS.com posted an interesting article, detailing the results of their long-term (10-months) longevity tests on several OLED and LCD TVs and monitors. The test is simple - display a CNN feed constantly, and checking what happens. Note that CNN changed their logo a bit a few months into the test, but the team did not make any changes to the test itself.

As is expected, OLED monitors and TVs suffer from image retention problems, and the CNN logo is visible in some of these panels, when showing a gray screen. Some TVs suffer more than others.
