A matte display is an electronic display with a matte surface. Matte displays feature a light-scattering antireflection layer, which reduces reflectivity at the cost of decreased contrast and color intensity under dimly lit conditions.

The image quality in displays with matte finish is not as sharp or bright as a glossy screen but is easier to color-match and calibrate with a printer.

While there are many different manufacturers of LCD monitors, the panels themselves are actually only manufactured by a relatively small selection of companies. The three main manufacturers tend to be Samsung, AU Optronics and LG.Display (previously LG.Philips), but there are also a range of other companies like Innolux and CPT which are used widely in the market. Below is a database of all the current panel modules manufactured in each size. These show the module number along with important information including panel technology and a detailed spec. This should provide a detailed list of panels used, and can give you some insight into what is used in any given LCD display.

Note:These are taken from manufacturer product documentation and panel resource websites. Specs are up to date to the best of our knowledge, and new panels will be added as and when they are produced. Where gaps are present, the detail is unknown or not listed in documentation. The colour depth specs are taken from the manufacturer, and so where they specify FRC and 8-bit etc, this is their listing. Absence of such in the table below does not necessarily mean they aren’t using FRC etc, just that this is how the manufacturer lists the spec on their site.

The decision to close the LCD business, by Samsung Display, will be completed by June of 2022 as the company faces tough competition from its Chinese and Taiwanese counterparts, reports GizmoChina.

The company has decided to focus on manufacturing organic light-emitting diode (OLED) and quantum dot (QD) displays, as OLED panels have started to become the norm in the smartphone market.

A recent Display Supply Chain Consultants (DSCC) revealed that the price of an LCD is 36.6 per cent of what it used to be in January 2014, the component"s peak production period.

No investment plan details have since been announced, and the employees of the LCD business are expected to be transferred to the QD business, the report said.

Samsung Display had decided to close its LCD business in late 2020, but the plans were delayed at Samsung Electronics" request due to a sudden increase in the prices of LCD panels during the COVID-19 pandemic.

Glossy screen finishes reflect less light overall than other screen finishes. As there"s less light reflected, the picture quality isn"t affected as much as semi-gloss screens. The perceived contrast ratio remains the same as blacks still appear deep and inky. Contrast is one of the most important elements of picture quality, so it"s safe to say that, overall, glossy screen finishes offer the best picture quality of any screen finish. This is also why matte screens are no longer around. The perceivable depth of blacks isn"t as great with matte, and so in that regard, the picture quality looks worse than it does with semi-gloss or glossy screens.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
