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
- OLEDs offer a much faster refresh rate and better viewing angles (great for games!)
- 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. The first displays will be 15.6" UHD (3840x2160) AMOLED panels that feature high contrast ratio, extreme color accuracy, full HDR compatibility, a very wide color gamut and remarkable outdoor visibility (for more details on Samsung's 2019 15.6" AMOLEDs, click here). SDC is targeting premium laptops, as these ultra high resolution panels are optimized for gaming, graphic design and video streaming.
Following Samsung's announcement, three companies quickly announced 15" OLED laptops - HP with its Spectre x360, Lenovo with the Yoga C730 and Dell with the XPS 15, Dell G7 15 and the Alienware m15. It is likely that at least some of these laptops will start shipping in March 2019 when SDC will actually start supplying the panels. Click here for our complete list of laptops with OLED displays.
What the future holds
If this first wave of OLED laptop displays will be successful, it is likely that Samsung will release more laptop displays - including smaller 13.3" OLEDs and 14" OLEDs. In addition we are looking forward to seeing laptops with flexible OLEDs and also ones with transparent displays (not sure why is that a good idea, but it sure looks great):
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, image retention (known as burn-in) is a real problem. 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. As OLED lifetime improves, image retention is also less visible - and it appears that as of 2019, the situation is improved enough that Samsung believes OLED can be adopted successful in laptop displays.
The latest OLED Laptop news:
HP announced a new edition to its 13.3" Spectre x360 13 laptop - which comes with an optional 13.3" 4K AMOLED display. HP will start shipping the Spectre x360 13 OLED in October 2019.
This is the first time we hear of this new 13.3" 4K AMOLED display. In 2016 and 2017 Samsung produced 13" laptop OLED displays - but with a lower 2560x1440 resolution. This was used in an 2016 HP Spectre x360 13 laptop and also in some Alienware gaming laptops. In February 2019 Samsung started to produce 15.6" 4K AMOLEDs for laptops - and it's great to hear that it is now adding a smaller laptop display as well.
The Verge recently reviewed another OLED laptop, the HP 2019 Spectre x360 15, which uses the same SDC 15.6" display. The Verge says that the OLED is tremendous, and the reviewer sees "no reason why someone would pick an LCD over this OLED, given the option".
The Verge posted a review of one of the world's first 2019 OLED laptops, the HP 2019 Spectre x360 15. The reviewer loves the OLED display: "The Spectre x360 15’s display is tremendous, and I see no reason why someone would pick an LCD over this OLED, given the option. It’s absolutely worth the higher cost (Ed: around $400)."
HP's Spectre x360 15 features an Intel Core i7 CPU, 16 GB of RAM and 512 GB of SSD storage. The OLED display is a 15.6" 3840x2160 panel produced by SDC. HP's Spectre x360 15 laptops are now shipping, the OLED models start at $2,299.
Last week we reported that Asus demonstrated an OLED gaming laptop - even though it still has some concerns with OLED displays and is not ready to release such a device commercially.
It turns out that Asus has another OLED laptop in the works - the ZenBook Pro Duo which actually features two screens - an SDC 15.6" 4K AMOLED main display and another, smaller 14" LCD that is placed above the keyboard. This is just a prototype, but according to reports this seems like a finished product, and it could reach the markets soon.
Asus recently launched a new gaming laptop, the Zephyrus S GX502, which uses a 15.6" 4K 120Hz LCD IPS display. At Computex 2019 in Taiwan, Asus demonstrated one of these laptops with an 15.6" SDC AMOLED display.
Asus says it has no immediate plans to release an OLED gaming laptop as it still has concerns over the shorter lifespan of OLED displays, image retention (burn-in) and long-term color accuracy. As soon as these concerns are resolved, Asus says it will push forward with incorporating OLED panels in gaming laptops.
In February 2019 Samsung Display started to mass produce its new 15.6" 3840x2160 OLED display panels, and some of the first 2019 OLED laptops are already shipping.
Korea-site The Elec says that according to its sources, Apple is "considering adoption" of OLED displays in its Pro laptop and tablets lines. The iPad Pro will adopt an 11" OLED while the MacBook Pro will adopt a 15.6" one.
Earlier this month Lenovo demonstrated a prototype 13.3" foldable OLED ThinkPad laptop. We speculated that LGD is the display supplier, and yesterday LGD's CTO confirmed this.
Lenovo said that it developed this device for over three years, and hopes to launched a commercial one in 2020. In October 2018 it was first reported that LG Display is working together with Lenovo on a 13.3" foldable OLED laptop device, but that was not confirmed until now.
Update: LGD confirms it is supplying the 13.3" foldable OLEDs to Lenovo's prototypes.
Lenovo demonstrated a prototype foldable ThinkPad laptop, that features a 13.3" foldable OLED display. Lenovo says that it developed this device for over three years, and hopes to launched a commercial one in 2020.
The reporters at The Verge really liked the device, but noted that the hardware is clearly not finished - the folding mechanism for example did not feel sturdy (and we all know this is critical in a foldable device) and the display itself suffers from "remarkably poor viewing angles".
