TFTLCD vsIPSLCD vs AMOLED

These LCD screens provide vibrant colors, high contrast, and clear images even at wide viewing angles, albeit at a premium price. This technology is frequently employed in high-definition screens, particularly in gaming or entertainment setups.

The Vivobook 15 Pro offers a glossy display which does help with avoiding the haziness of a matte finish, but ASUS has not added any sort of anti-glare coating, so the Vivobook Pro 15 is very reflective. This is an area where most PC manufacturers need to up their game. Dell has some wonderful anti-glare coatings on their XPS lineup, but most glossy laptops offer none.

If you're considering purchasing a new monitor, you might be deliberating on the choice of display technology. In today’s market, two primary types of computer monitors stand out: TFT LCD monitors and IPS monitors.

Representation and Reproduction of Colour: Winner. the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.

Image Sticking or “Ghosting”: No clear winner emerges as it depends on the display screen manufacturer. Generally speaking, TFT is less prone to experiencing this issue.

IPS (In-Plane Switching) technology represents an advancement over traditional TFT LCD display modules, retaining the same basic structure while offering enhanced features and broader applicability.

ASUS does offer an included ICC color profile as well, and the device is Pantone Validated for color accuracy, but that is for the P3 gamut of course. The display also reduces blue-light emissions by 70% from some value that is not provided.

The Vivobook’s OLED display also supports HDR, and is DisplayHDR True Black 600 certified, which is VESA's highest tier for OLED displays. Thanks to the high contrast, performing HDR on an OLED display is much easier than on an LCD where you need a very bright backlight to compensate for the high black levels of LCD displays.

TFTLED

Due to the wide-set nature of IPS technology, display screens made with IPS technology typically feature a wider aspect ratio. This results in improved visibility and a more realistic viewing experience with a stable effect.

OLED does have drawbacks though, and they can be significant for a laptop computer. While power draw when displaying darker content is an advantage, when displaying bright or white images or graphics the power draw of OLED can exceed an LCD at the same brightness. OLED also suffers from issues with burn-in, as the subpixels themselves age over time with use, and in an uneven fashion depending on the color.

Considering the price point of this laptop, it is one of the least expensive ways to get into an OLED laptop. As long as you are aware of the downsides of OLED with its possible burn-in issues and the P3 gamut causing overblown colors for most software the Vivobook Pro 15 OLED display is a stunner.

Energy Consumption: Winner. Although TFT LCDs consume around 15% more power compared to IPS LCDs, IPS displays have lower transmittance, which necessitates them to consume more power through backlights. Therefore, TFT LCDs contribute to better battery life.

Unlike the gamut test which measures the primary and secondary colors at their 100% levels, the saturation test measures them at 4-bit steps across 0-100%. This shows that across most of the sweep, the color accuracy of the Vivobook Pro 15 OLED is quite good, and the Cyan issue seen in the gamut test happens only when the display is getting close to 100% levels for that color. Yellow is actually the least accurate color for most of the range.

To see how the ASUS Vivobook Pro 15 OLED display performs, it was run through our display testing. For brightness levels and contrast, the X-Rite i1Display Pro colorimeter is used, and for color accuracy testing, the X-Rite i1Pro 2 spectrophotometer takes the stage. As always, thanks to our friends at Portrait Displays for their Calman software suite which we utilize with a custom workflow. As always, we test all displays at 200 nits brightness.

20221221 — The key distinction between the two is that the Nit measures luminance or brightness of an object, and lumens measure how much light is being emitted.

Despite the 15.6-inch OLED display, the Vivobook Pro 15 still gets quite bright at almost 400 nits. ASUS claims it can peak at 600 nits brightness which will be for a much smaller section of the display than the full-screen white we test on. The display also has a very wide range of brightness, going all the way down to 4.6 nits at 0%.

Switching to the software side of matters, Windows 10 offers a dark mode, and ASUS has included their own tweaks to take advantage of OLED’s strengths, but in the PC world a significant amount of software still defaults to a light theme, which can create a higher power draw on OLED versus LCD. That, coupled with the burn-in of often static content being displayed have certainly slowed the adoption of OLED in the laptop space.

Both TFT and IPS displays are active-matrix displays, meaning they cannot emit light on their own like OLED displays. Instead, they require a backlight of white bright light to generate the picture. Modern panels often utilize LED backlighting (light-emitting diodes), which consumes less power and requires less depth by design. Neither TFT nor IPS displays can produce color independently; instead, there is a layer of RGB (red, green, blue) color filters in each LCD pixel to produce the colors visible to consumers. Upon closer inspection with a magnifier, RGB color can be seen in each pixel. By toggling the on/off switch and adjusting brightness levels of RGB, a wide range of colors can be achieved.

Industry nomenclature: TFT LCD panels or TFT screens can also be referred to as TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology.

TFTLCD

Fast Response Time: Winner. IPS TFT screens typically have a response time of around 0.3 milliseconds, whereas TN TFT screens have a response time of around 10 milliseconds. This significant difference makes TN TFT screens unsuitable for gaming.

The panel underlying the Vivobook Pro 15 OLED is a Samsung AMOLED part, which other sources have pegged as the ATNA56YX03-0. This means it's a true RGB panel, without any kind of color filters (ala WOLED), similar to Samsung's phones.

Although ASUS includes an ICC profile, they appear to be calibrating the laptops in batches, which means the color correction is not finely tuned to the individual panel. We generally consider a device with a dE2000 under 3.0 to be considered accurate, and for most of the range the Vivobook OLED does fall under 3.0, but then around 65% brightness the error levels start to creep up as the red levels go too high. The average is just over 3.0, so this is still an accurate display, but the error level at 100% is significant. That is why we always include the entire graph.

In a world where OLED has become much more common thanks to it being prevalent in the smartphone space, it is still special to see it in a notebook. This is not a perfect implementation, but the insane contrast just never disappoints. Sadly Windows still does not handle non-sRGB color gamuts very well, so even though ASUS has done a reasonable job calibrating the display, most of the time the color accuracy will be terrible unless you are using a color managed application.

Finally we have the colorchecker swatch, which shows the target color on the bottom of the image and the achieved color on the top of the image. This is a relative test as any inaccuracies in your own display will skew the result, but very much shows how the Vivobook Pro 15 biases towards red.

TFT LCDs have the capability to deactivate certain pixels while activating others, allowing the screen to operate with minimal energy consumption by manipulating the liquid crystal molecules between two electrodes. Capacitors and transistors are integral components of TFT LCDs, playing a crucial role in ensuring the monitor functions efficiently while producing vibrant, consistent images.

As previously discussed, this notebook targets the P3 D65 gamut rather than sRGB. Overall it is able to achieve that level, although cyan is well past its target. The average error level of 3.8 is quite good, but again points to a batch-corrected display rather than individual panel calibration.

Probably the biggest single advantage of OLED is that it offers an (effectively) infinite contrast ratio. Unlike an LCD light which uses filters to block a white LED backlight, OLED pixels themselves are the light source and can be turned off completely which means OLED offers a much deeper black level than any LCD can achieve. In addition, the OLED subpixels can generally offer a wider range of colors than most LCDs. OLED can also be very stingy with power when displaying black or dark images or graphics. In the smartphone world, most top-tier phones are now OLED and offer a dark mode enabled by default to reap the benefit.

The display in the Vivobook Pro 15, again, thanks to its OLED roots, offers a wider color gamut than a typical laptop as well. The Vivobook Pro 15 is marketed with DCI-P3 color support, although that is technically incorrect, as what it offers is actually P3 D65 color support – DCI-P3 is a cinema standard with a different white point. It is hard to fault ASUS here since most companies make the same mistake, but all we can do is point out the error when we see it.

OLED is right in the name of the product, and it is certainly one of the key differentiators with the Vivobook Pro 15 notebook. OLED of course stands for Organic Light Emitting Diode which is a completely different display technology than the traditional Liquid Crystal Display (LCD) that the vast majority of notebooks employ. OLED has some major advantages over LCD which have translated into it dominating the smart phone market, as well as being the best option for televisions, but it has most certainly not won over the PC space.

TFT, or Thin Film Transistor, refers to the technology employed in LCD displays. This type of LCD is also commonly known as an active-matrix LCD. If you're interested in delving deeper into understanding TFT Displays, we have additional resources available for you.

To combat this, the OLED panel manufacturers will vary the size of the subpixels. Blue ages the quickest, so the blue subpixel is the largest to compensate. This also means there are fewer blue subpixels than red and green, so there will not be the same resolution across all of the colors.

As far as contrast, it is basically infinite thanks to the OLED display being able to turn off the subpixels completely. Case in point: our meter read 0 nits on the black frame in our test workflow. We normally have a graph for contrast, but when the maximum brightness of 395 nits was divided by 0 nits, strange things happened, so that graph will have to be skipped for this review.

Both P3 gamut support and HDR are advantages over most other notebooks. Or at least they should be. Sadly, Windows does not offer great support for either HDR or wider than sRGB color spaces. There is no native color management system in Windows which will display sRGB content at the correct color levels on a wider than sRGB display, which means the colors will be over-saturated unless you are using a properly color-managed application such as Adobe Photoshop. That means most content you look at on this notebook will be the oversaturated. That is a sad thing indeed, because the OLED display does look amazing.
