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. This means it's a true RGB panel, without any kind of color filters (ala WOLED), similar to Samsung's phones.

The panel underlying the Vivobook Pro 15 OLED is a Samsung AMOLED part, which other sources have pegged as the ATNA56YX03-0. 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. Blue ages the quickest, so the blue subpixel is the largest to compensate. To combat this, the OLED panel manufacturers will vary the size of the subpixels. 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. 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 does have drawbacks though, and they can be significant for a laptop computer. In the smartphone world, most top-tier phones are now OLED and offer a dark mode enabled by default to reap the benefit. OLED can also be very stingy with power when displaying black or dark images or graphics. In addition, the OLED subpixels can generally offer a wider range of colors than most LCDs. 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. Probably the biggest single advantage of OLED is that it offers an (effectively) infinite contrast ratio. 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. 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 is right in the name of the product, and it is certainly one of the key differentiators with the Vivobook Pro 15 notebook.
