OLED (Organic Light Emitting Diode) is a display technology that is brighter, more efficient, thinner and feature better refresh rates and contrast than an LCD display. OLEDs deliver the best picture quality ever and OLED displays have been used in smartphones, wearables and TVs.
Why are OLED displays better than LCDs?
- In OLED displays, each pixel emits light independently (in LCDs, there is a white backlight).
- The contrast ratio of OLEDs is much better than in LCD, so are the refresh rates and the viewing angles.
- OLEDs are thinner and lighter than LCDs, and can be made flexible, foldable, rollable and transparent.
- OLEDs are more efficient, as only lit pixels draw energy. A smart user interface can result in very power efficient OLED displays!
2019 - OLED laptops finally arrive
OLEDs are already very successful in smartphone displays (over 500 million panels produced annually, adopted in smartphones from Apple, Samsung, Sony and others), OLED TVs and wearables. While in early 2016 several laptop makers announced the first OLED laptops (such as the Lenovo X1 Yoga with its 14" 2550x1440 AMOLED and the HP Spectre X360 with its 13.3" 2560x1600 AMOLED display), these laptops were produced in small quantities and quickly discontinued.
In early 2019, Samsung finally announced it start mass producing OLED displays for laptops. Since then we have seen many laptops from HP, Dell, Asus, Gigabyte, Lenovo and others adopt OLED displays, first at premium models and slowly in medium-range laptops as well.

Samsung, and other display makers, are expanding OLED laptop production capacity as demand for IT in general is rising and consumers prefer OLED displays.
Image retention (burn-in)?
One of the major drawbacks of an OLED display is that because each pixel is driven independently and because the lifetime of an OLED emitter is limited, OLED panels suffer from image retention (known as burn-in). A much-used pixel is less bright than a pixel that hasn't been driven a lot (for a more technical explanation, click here).
In computer user interface this is a problem - as some UI elements are quite fixed (toolbars, icons, etc). There are some technologies to handle this problem - for example by measurement and compensation, by using a tandem architecture to extend lifetime, and more. The situation has improved much in recent years, to the point where OLEDs are very much suitable as laptops displays.
The latest OLED Laptop news:
Following strong demand for IT devices, and Samsung's success in the OLED laptop market, OLED makers have began to plan building new OLED production lines specifically for IT applications: laptops, tablets and monitors.
Several OLED makers, including Samsung, LG and BOE, are considering building 8.5-Gen production lines for this market. In fact DSCC estimated that there are 11 such lines under development right now. But it turns out that this is not so simple as designing the evaporation equipment for larger substrates is a challenge.
DSCC sees fast growth ahead for OLED displays in the notebook market, while miniLED LCDs will stagnate
DSCC says that in 2022, MiniLEDs will hold a 49% share in the advanced notebook market, while OLED will hold a 51% share. Looking into the future,MiniLEDs sales will increase slightly, while OLED sales will rise much faster, and by 2026 OLED shipments to the notebook market will reach over 40 million panels, and hold a 75% market share.
Looking at specific vendors, DSCC sees Asus as the leading OLED notebook maker, with a market share of 55%, followed by Lenovo at 17% and both Samsung and HP at 11%. The market ranking will remain pretty constant in 2022 as a whole.
Samsung Display officially announced its latest laptop OLED display, a 15.6" 240Hz panel aimed for gaming laptops. The display offers a QHD (2560x1440) resolution, a response time of 0.2 ms and VESA DisplayHDR 600 certification.
Samsung also announced that the first laptop to adopt the new display, which will enter production soon, is MSI's Raider GE67 HX, which is already available for pre-orders.
DSCC says that global OLED revenues in Q1 2022 were around $9.5 billion, the same as in Q1 2021, even though unit shipments declined 4%.
Smartphone remained the leading OLED application, with a 79% revenue share, even though shipments decreased 8% (and revenues decreased 3%). The second largest application by shipments is wearables (16% in Q1 2022 by shipments and in 6% market share by revenues).
Samsung Display unveils new OLED displays at SID Displayweek 2022. First up is the Flex G flexible display, which folds inwards twice, and the Flex S, that can fold both inwards and outwards.
Samsung is also new rollable displays - a 6.7" slidable display that can expand and a larger 12.4" slidable OLED that can expand from both ends. When close, the display is 8.1" in size.
Samsung Electronics reported its financial results for Q1 2022. Revenues hit a new record of 77.78 trillion Won ($61.2 billion USD) and the operating profit was 14.12 trillion Won ($11 billion USD).
Samsung Display's revenues were 7.97 trillion Won ($6.3 billion USD) with an operating profit of 1.09 trillion Won ($900 million USD). Samsung says its mobile display earnings improved from 2021, led by strong demand for OLED smartphone displays and growing adoption of OLED displays in laptops and gaming devices.
Samsung Display announced that its OLED displays for laptop applications has received 'Halo Free' verification from the safety science leader, UL, for its glare-free and sharp picture quality.
Samsung explains that LCD displays suffer from light-blurring which occurs when the outline of a bright subject appears white on an image with sharp contrast. This is because even with local dimming, LCDs cannot adjust the backlight brightness exactly on the edge. OLEDs, with their self-lit pixels, do not suffer from this.
Demand for larger mobile OLED displays, for laptops, tablets and monitors is on the rise, and display makers are looking into 8.5-Gen OLED production lines dedicated to the IT market.
According to a new report from Korea, BOE is moving forward with its plans to establish an IT AMOLED production line. The company is aiming to establish a 8.5-Gen (2250x2600 mm) production line at its B16 fab in Chengdu. BOE's goal is to start production by the end of 2024, with an initial capacity of 15,000 monthly substrates.
According to reports in Korea, HP has decided to launch a foldable OLED laptop by the end of the year. HP will source 17-inch 4K in-folding OLED panels from LG Display.
The Lenovo ThinkPad X1 Fold
The Elec suggests that LGD will start mass producing the 17-inch panels in Q3, with plans to produce around 10,000 units.
DSCC estimates that just over 10 million foldable OLED displays shipped in 2022, and the market is set to grow to 86 million units by 2026 (54% CAGR).
DSCC says that foldable smartphone revenues rose 342% in 2021, and have reached $5.8 billion. The most popular foldable smartphone was the Galaxy Z Flip 3 (51% market share in 2021), followed by the Galaxy Z Fold 3 (26% market share) and the Huawei Mate X2 (6% market share).
