\n\"\"<\/p>\n

OLED panel manufacturer, LG Display today announced some further details of one of their new panels which was teased a couple of days ago<\/a> in a promotional video (along with other new updates). The newly announced OLED panel offers a 27\u2033 screen size, with a 3840 x 2160 \u201c4K\u201d resolution and a 240Hz refresh rate. This is the first time they\u2019ve produced a 27\u2033 4K panel, following on from Samsung Display\u2019s competing QD-OLED panel released in 2025.<\/p>\n

This LG Display panel also offers support for a \u201cdual-mode\u201d function which allows you to double the refresh rate to 480Hz, at a lower 1080p resolution. Most interesting of all is the switch to a true RGB-stripe sub-pixel layout, doing away with the white sub-pixel and helping to improve text clarity and reduce fringing.<\/p>\n

True RGB stripe layout<\/p>\n

\"\"<\/p>\n

The RGB stripe sub-pixel structure arranges the three primary colour subpixels \u2014 red, green, and blue \u2014 in a straight line, significantly reducing visual distortions such as colour bleeding and fringing, even at close viewing distances. This is a change from their earlier \u201cWOLED\u201d panels which had an added white sub-pixel which was used for boosting brightness. In the past the earlier WOLED panels were arranged in an RWBG layout, but this was later updated and improved somewhat to RGWB with some of their newer panels.<\/p>\n

We\u2019d already seen significant improvements in text clarity on competing QD-OLED panels of this size and resolution, and although the increased pixel density alone would likely have solved most lingering issues anyway, it\u2019s great to see LG Display just shift to a true RGB-stripe layout with the new panel. This structure is \u201coptimized for operating systems such as Windows and for font-rendering engines, ensuring excellent text readability and high colour accuracy\u201d.<\/p>\n

LG Display mention a pixel density of 160 PPI in the press release<\/a>, although if the actual panel size remains the same as previous 27\u2033 class monitor panels (at 26.5\u2033), it would be more like 166 PPI in reality. Although OLED panels using the RGB stripe method existed before (e.g. the professional-focused monitors featuring panels from JOLED), their maximum refresh rate reached around 60Hz, making them unsuitable for use as gaming monitors.<\/p>\n

High refresh rate<\/p>\n

\"\"<\/p>\n

LG Display\u2019s new panel is the first in the world to achieve a 240Hz refresh rate while maintaining an RGB stripe structure. It incorporates the company\u2019s specialized Dynamic Frequency & Resolution (DFR) technology (\u201cdual-mode\u201d), allowing users to directly switch between high-resolution (UHD 240Hz) and high-refresh-rate (FHD 480Hz) modes.<\/p>\n

They explain that as they \u201cdeveloped [their] new pattern optimized for monitor use, it applied various new technologies \u2014 such as increasing the aperture ratio, which is the proportion of the pixel area that emits light. As a result, it achieved the world first of implementing both an RGB stripe structure and a high refresh rate simultaneously.\u201d<\/p>\n

4th Gen Tandem OLED?<\/p>\n

\"\"<\/p>\n

This new panel should be considered part of their 4th Gen technology as far as we can tell although information shared at the moment is not complete and somewhat confusing. We\u2019re seeking further clarification from LG Display on this area. <\/p>\n

We do know that the new 27\u2033 4K panel was mentioned in a recent promotional video<\/a> which talked about their \u2018Tandem WOLED\u2019 and \u2018Tandem OLED\u2019 technologies, implying it should fall in to one of those categories. Traditionally it\u2019s been easy to just refer to LG Display\u2019s OLED monitor panels as \u201cWOLED\u201d but clearly that won\u2019t be appropriate with these new RGB-stripe panels without the \u201cW\u201d element. Their accompanying press release<\/a> explained that \u201cTandem WOLED applies to large-sized OLED TV and monitor panels, which are now distinguished from Tandem OLED for small- and medium-sized panels, including automotive, tablet, and laptop displays.\u201c<\/p>\n

If the new 27\u2033 4K panel is not a \u2018Tandem WOLED\u2019 panel, does that mean it\u2019s the same as their \u2018Tandem OLED\u2019 panels used in laptops and smaller devices? LG Display explain that those panels incorporate dual stacked RGB layers, and it\u2019s not clear if that\u2019s what is used here for this new 27\u2033 4K panel. That\u2019s used for smaller display panels and so it\u2019s likely it is the same technology used here, but strangely there\u2019s zero mention of \u201cTandem\u201d in the press release<\/a> which announces this new panel. This also has a potential impact on panel performance in other areas such as lifespan, brightness (discussed below) and black depth retention in the presence of ambient light.<\/p>\n

We\u2019re seeking clarification from LG Display on how this new panel is classified and its panel structure.<\/p>\n

Panel brightness<\/p>\n

Another thing that remains unclear at the moment is what impact removing the white sub-pixel and increasing the pixel density will have on brightness specs. Without the white sub-pixel boost we\u2019d expect a drop in the brightness specs being advertised, it probably won\u2019t reach the same 1500 nits peak that their most recent 4th Gen Tandem WOLED panels have reached. Whether or not it can meet the VESA DisplayHDR 500 True Black certification tier is also unknown at this time.<\/p>\n

With only RGB sub-pixels now available, this will offer an \u201cadditive\u201d approach to colour brightness, which should mean we get higher colour volume in HDR \u2013 i.e. colours will be maintained even at maximum brightness. This will behave differently to previous WOLED panels where the white pixel would be used to boost brightness, but this can lead to some washout of colours and \u201cvolumetric collapse\u201d when considering colour volume for HDR for lower APL scenes.<\/p>\n

More news at CES<\/p>\n

No doubt there will be more news and information at CES in early January, and we will be visiting LG Display\u2019s booth to get all the latest updates. They\u2019ve already teased another new OLED panel, a 39\u2033 ultrawide with a 5K2K resolution, so we hope to see that exhibited as well. Please keep in mind that this is an announcement about an OLED panel, not any specific display at this stage. It remains to be seen whether familiar monitor brands will adopt this new panel and when, but hopefully we\u2019ll see some news and announcements at CES from the likes of Asus and LG Electronics, who often used LG Display\u2019s panels.<\/p>\n
