We're seeing more and more OLED displays in laptops, phones, and TVs, and with these brilliant upgrades come some important questions. What is OLED and how does it compare to the more standard LCD? How do OLED displays work? Is burn-in still an issue? What are some of the pros and cons when buying an OLED display? If you've been wondering what the deal is with these displays, we can hopefully answer some of your questions.
What is OLED and how does it compare to LCD?
You've likely heard about light-emitting diodes (LED), the small lights used just about everywhere these days in lieu of incandescent style bulbs, but OLED, which stands for "Organic Light Emitting Diode," is a display technology that relies on layers of organic (hydrogen and carbon) material that light up when placed between anode (positive) and cathode (negative) layers and given a current.
An emissive layer next to the cathode takes on electrons, while a conductive layer next to the anode has electrons removed, creating holes. When electrons and holes meet, the result is a particle of light, or photon. This process happens incredibly fast, and as long as the display has power, it continues emitting light. To get the brilliant color associated with OLED displays, layers of colored film are used.
Because there's no need for a separate backlight like with LCD displays, you'll generally see lower power consumption with OLED, no backlight bleed — that light that shines from the edge of your laptop's display when showing dark images — a thinner overall construction, better color reproduction, and better contrast.
When we reviewed LCD and OLED versions of Lenovo's ThinkPad X1 Yoga, for example, we saw very different results when testing color accuracy. The OLED display hit 100 percent sRGB and 100 percent AdobeRGB, while the LCD display with IPS hit 96 percent sRGB and 72 percent AdobeRGB. The difference in everyday use is immediately noticeable.
You can also depend on a bright picture, fast refresh rate, better viewing angles, and far better flexibility, which is a feature we saw taken advantage of in Samsung's Galaxy Fold and, more recently, Lenovo's ThinkPad X1 foldable prototype PC.
OLED displays can be paired with touch and pen functionality, and they can even be made transparent. Aside from phones and laptops, you'll often find OLED displays in standard desktop PC monitors, TVs, and VR headsets like the Samsung Odyssey+. Once you start looking at the positives, it's clear why so many manufacturers are making the move to OLED, but there are still some downsides to keep in mind.
What are the downsides of OLED displays?
The brilliant contrast of an OLED display comes with a tradeoff. When creating a mostly-white picture — like when word processing and web browsing, two common activities on a laptop — each sub-pixel must shine bright, which will suck more battery power.
This is quite different than an IPS panel, which will consume the same amount of battery whether the display is showing primarily white or primarily black colors. The backlight sets itself at a certain brightness and doesn't move unless you tell it to. However, if you happen to use apps with dark themes, or you enjoy watching movies that have a lot of dark scenes, you should see battery life actually improve. OLED displays simply stop using a pixel to create a dark color, which in turn takes less battery power.
One of the biggest problems that many consumers have with OLED displays is that they're prone to burn-in. An image that's shown too long on an OLED display — something static like the Windows 10 taskbar is a perfect example — can remain visible even when not actually displayed, like when you're watching a movie. Before panic sets in, know that OLED burn-in is reported a lot less frequently than it used to be on plasma TVs. Remember the minimap from games remaining after you turned off your Xbox? That's not likely going to happen here to the same extent, even if you game on your laptop with an OLED display.
Laptop manufacturers are taking strides to reduce the risk of burn-in on OLED laptop displays, similar to what Microsoft implemented with its Xbox screen dimmer. You can, for example, choose to always dim the taskbar and background, or you can choose intervals in which it will turn on when the laptop is idle. A good practice on laptops without dedicated settings is to make your display dim or turn off after a few minutes of idling. If you take good care of your OLED display, chances are you will not experience any severe image retention.
There's also the price factor. You're going to pay more for an OLED display than for an LCD counterpart, and whether or not that cost is worth the upgrade is really up to you and your usage scenario.
Does it make sense for you to buy OLED?
While OLED displays will likely one day be cheaper than their LCD counterparts, the current upgrade cost in a laptop is certainly noticeable and you'll pay more for OLED TVs and desktop monitors. Paying extra for OLED will come down to whether or not you think you can take advantage of the excellent color reproduction, wide viewing angles, high contrast, and fast refresh rate. Professionals in design and development work are prime targets for OLED displays, as are gamers who want the best picture possible.
There are some exciting laptops, monitors, and TVs out there with OLED display technology, and while a lot of people will get by just fine with LCD, others will prefer to have the latest tech and the best picture possible.
Something like Dell's refreshed XPS 15 7590 laptop comes with a 15.6-inch 4K OLED display and the internal hardware, including discrete NVIDIA graphics (GPU) and Intel Core i9 processor (CPU), to handle a heavy workload, making it a prime option for those who want a premium laptop with desktop performance.
