Eye Care

70% blue-light reduction for eye care

Blue light is known to cause visual discomfort and disrupt sleep quality. However, due to the nature of the special organic lighting materials in an OLED display, ASUS OLED laptops emit 70% less harmful blue light1, and they’re also certified by TÜV Rheinland and SGS. More importantly, unlike traditional blue-light filters, shifting the spectrum means there’s no need to compromise colour accuracy.

Eye Care

Eye care, even more critical for children

Since children’s eyes are not fully developed, with a more transparent lens and cornea, harmful blue light can penetrate the eye more easily, potentially causing premature aging of the retina. Research4 has shown that in a five-year-old child's eyes, approximately 60% of the received blue-light emissions pass through to the retina, compared to only around 20% for a 60-year-old adult. With ASUS OLED displays, the significantly lower blue light levels mean better eye care for children.

Response Time

Fastest response time on any laptop for motion clarity

For a display, response time is the time taken to replace one colour with another: the faster the time, the better motion is reproduced. The diagram below shows a colour transition from purple to blue. On an ASUS OLED, this transition takes only 0.2 milliseconds, while on an LCD, it might take 10 ms or longer. This makes a lot of difference, since OLED colours and images look correct for most of the time a frame is displayed, whereas LCD images may be blurry during the transition process.
ASUS OLED displays have a 0.2 ms response time — the fastest of any laptop, and 50x faster5 than the average laptop LCD display. This ensures smoother fast-paced action scenes, low-latency gameplay, and subtle details like blur-free text scrolling. In effect, the smooth visuals on an OLED display can rival those on an LCD display with a much higher refresh rate.

MOTION CLARITY

Ultimate 120 Hz / 0.2 ms for exceptional motion clarity

The new premium ASUS OLED display with 120 Hz refresh rate and 0.2 ms pixel response time is incredibly smooth and clear. In fact, both surprisingly and counter-intuitively, the 120 Hz / 0.2 ms OLED display is faster than a 165 Hz / 3 ms LCD IPS display — because it reduces ghosting to an indiscernible level. Simply put, this means even fast-moving visuals are smoother and clearer than ever.

MOTION CLARITY

How 120 Hz / 0.2 ms OLED display has better motion clarity than 165 Hz / 3 ms LCD display

It seems counter-intuitive that a 120 Hz / 0.2 ms OLED display could outperform a 165 Hz / 3 ms LCD display rival — so how is this possible? Well, the LCD panel takes precisely 6.06 ms to refresh each frame, but it takes another 3 ms of response time to process the correct colours. That’s a total of 9.06 ms to fully load the image. A 144 Hz / 12.5 ms LCD display takes even longer, at 19.44 ms to show the full, final frame of each image. But with its extreme-speed response, a 120 Hz / 0.2 ms OLED display takes just 8.5 ms to process the same — making it even faster than a 165 Hz / 3 ms LCD display.

Colour Volume

Colour-perfect at any brightness

ASUS OLED laptops maintain a 100% DCI-P3 colour gamut at both high and low brightness levels, while on a standard LCD laptop the colour gamut is reduced dramatically at low brightness levels. At a gray-level brightness of 16 G, LCD laptops only have an 11% DCI-P3 colour gamut, while ASUS OLED laptops maintain a 100% DCI-P3 colour gamut.

Colour Volume

OLED has 1.6x colour volume compared to LCD

On conventional LCD displays, detail and colour quality usually decrease dramatically as the brightness is reduced. But ASUS OLED laptops are able to show great detail at lower brightness settings due to their high contrast and their ability to maintain a wide colour gamut at low brightness. When calculating the 3D colour volume — which adds illumination to the traditional 2D colour gamut — ASUS OLED displays have about a 60% higher colour volume, offering better colour performance at any brightness level.

Perceptual Brightness

OLED has much higher perceptual brightness

ASUS OLED laptops can maintain good colour reproduction at any brightness level, so you can freely adjust the screen's brightness to suit your working environment, while still enjoying exceptionally vivid colours. For example, in the living room environment (usually illuminated at about 100 lux), you only need 177 nits brightness in an OLED display to produce the same clear image as 400 nits brightness in an LCD display. At the lower brightness levels needed on OLED displays, there's less harmful blue light emitted.

Contrast

True black: See the unseen

ASUS OLED laptops reproduce blacks perfectly. An OLED pixel consists of three sub-pixels, each with its own self-generated illumination: a Full HD (1920x1080) display has 2,073,600 pixels, which means it has 6,220,800 self-illuminated sub-pixels, compared to just a few dozen LED backlights in a Full HD LCD display. When displaying black on an OLED display, the pixel is simply turned off to produce the darkest possible black. This enables extremely crisp and clear images even in the darkest scenes. You’ll be surprised to see how many new details you’ll spot in your favourite films!

ASUS OLED Care

Protecting your OLED display

ASUS OLED laptops come with an ASUS-exclusive OLED Care mechanism that’s proven to protect your OLED display. Image persistence, or burn-in7, on an OLED display can occur if a static high-contrast image is displayed for a prolonged period of time. To avoid this, when your ASUS laptop is idle for over 30 minutes, our specially designed Pixel Refresh feature kicks in. We also include Pixel Shift technology, which moves displayed pixels slightly to avoid consistently showing static images on your desktop. This significantly reduces the chance of burn-in by making sure all the pixels are illuminated and darkened equally, thus protecting the display from visible colour shifts over time.

Harmful effects on retinal cells

Cone cells are the cells in the eye's retina that enable colour vision. Blue light is often more harmful to these cells compared to other wavelengths of light. In experiments conducted by the Gifu Pharmaceutical University in Japan2, mice cone cells were subjected to red, green, and blue light sources. The survivability of the cone cells under blue light exposure dropped dramatically to 20% after 24 hours, while cone cells exposed to other colours retained around 100% survivability.

Blue light disrupts sleep cycles

When it gets dark, your brain produces the hormone melatonin, which helps to maintain the correct scheduling of your daily sleep cycles. According to a Stanford University study3 the production of melatonin can be blocked by exposure to blue light at night, and potentially cause sleep disruption.

Protect young eyes with OLED

In a five-year-old child's eyes, approximately 60% of the received blue light emissions pass through to the retina, compared to only around 20% for a 60 year-old adult. The potential harmful effects of blue light on young children will be significantly reduced if you choose an ASUS OLED display.

Consistent colour in any environment

ASUS OLED laptops can maintain good colour reproduction at any brightness level, so you can freely adjust the screen's brightness to suit your working environment. So even with a lower brightness, you can still enjoy exceptionally vivid colours. At the lower brightness levels needed on OLED displays, there's less harmful blue light emitted.

High coverage of HDR standard

The industry HDR standard covers a huge range of brightness from 0.0005 nits — the lowest measurable level — up to 10,000 nits. The true blacks and high brightness possible with OLED displays give them a 75% coverage of the HDR standard, compared to about 46% for LCD displays.

Millions of pixels, individually illuminated

The pixels on an OLED display each contain three sub-pixels. A Full HD (1920x1080) display has 2,073,600 pixels, which means it has 6,220,800 sub-pixels. Each sub-pixel self-illuminates independently, unlike LCD displays with pixels that need to be backlit, usually by just 50 or 60 LEDs. This means that it's easier to achieve true black on an OLED display, by simply turning off a pixel. This can't be done on an ordinary LED display, because the backlight can't be turned off with such granularity. This fact also gives OLED displays exceptionally high contrast.

Clearer motion than ultrafast LCD displays

The ultrafast 0.2 ms response time of an OLED display means it can switch colours and images much quicker than even LCD displays with higher refresh rate. So a 90 Hz, 0.2 ms OLED display shows much smoother and clearer motion than a 144 Hz, 25 ms LCD laptop display.
