LG.Display Latest LCD Panel Development Plans – March 2023

Share this content

We have some updates from LG.Display about their LCD panel development plans which is always interesting to see. OLED panels will be covered in a separate article as there’s lots to talk about there too! As a reminder, this is LG.Display as a panel manufacturer, as opposed to LG Electronics the monitor/display manufacturer, but it gives an indication of where monitors are likely to go in the future by looking ahead at the panel production plans. LG.Display make a large portion of the IPS-type panels in the market which is always of interest.

Please keep in mind that the production dates are not set in stone and may change, and there is then also a lag of several months before a panel is produced, then used in a display and launched to market. We will update our panel parts database with all the new information we have as well as best we can.

If you missed it, our last update for LG.Display was June 2022 and worth a read back. Here are the highlights from this new update. We have also recently published an update for AU Optronics and have one for LG.Display OLED panels and for another supplier, BOE coming soon so stay tuned for those.

Expansion of IPS Black Panels in the Professional Space

Part of LG.Display’s focus is in the professional part of the monitor market, producing panels aimed at content creators, designers and studios. They plan to increase resolution, continue to improve contrast ratio compared with traditional IPS technology, and also bring higher-end Mini LED backlights to more mainstream displays. IPS Black is a big part of that focus, and it seems this technology is for now still reserved for professional use, with no high refresh rate options currently being developed. That’s a shame, as we know a lot of people are interested in that possibility in the future.

The IPS Black panels offer significantly improved contrast ratio compared with traditional IPS panels (2000:1+ spec expected). We looked at IPS Black last year, so you can see our thoughts and comparisons with other IPS technologies in our video here.

LG.Display already produce IPS Black panels in 27″ (4K), 31.5″ (4K) and 34″UW (3440 x 1440) options. The new IPS Black panels being planned are:

  • 49″ super ultrawide IPS Black with 5120 x 1440 resolution – this panel would be a new ultrawide format in a larger screen size for LG.Display’s IPS Black tech. It would also have a subtle 3800R curvature, 32:9 aspect ratio, and usual specs like 98% DCI-P3 gamut and 350 nits brightness. It should be in production now as of Q1 2023
  • 37.5″ ultrawide IPS Black with 3840 x 1600 resolution – this panel would also be a new ultrawide format in a larger screen size for LG.Display’s IPS Black tech. It would also have a 2300R curvature, 24:10 aspect ratio, and usual specs like 98% DCI-P3 gamut and 300 nits brightness. It should be in production now as of Q1 2023
  • 27″ sized IPS Black panel with a 5K resolution and Mini LED backlight – This panel has a 5120 x 2880 resolution giving a very high pixel density of 218 PPI. Whether or not this is really needed when we already have high density 4K panels in this size is questionable in our opinion, although for professional work, it’s perhaps desirable to improve that further. The more interesting element to this new panel for us is that it will be based on LG.Display’s IPS Black technology and paired with a high-end Mini LED backlight. The Mini LED backlight is expected to have 1560 dimming zones which should offer impressive levels of control and dimming. Considering that the first generation of FALD backlights in this screen size had 384 zones when first released, this is a massive improvement. HDR1000 support is listed along with a 98% DCI-P3 colour gamut. This panel is only in planning stage at the moment with production penciled in for H1 2024 but very much TBC
  • 27″ 1440p IPS Black option – with the current 27″ panel in production only being available with a 4K resolution, it’s good to see a more mainstream 1440p (2560 x 1440) version in the plans. This should help make IPS Black more affordable in mid tier monitors, and also for those who don’t want the complications of powering or scaling a 4K resolution on a smaller sized screen like this. This is pencilled in for possible Q4 2023 production.

Update on the new 27″ 4K IPS panel with Mini LED and 144Hz

This was covering in our last update in June 2022 but of note in the forthcoming Mini LED panel line-up is a 27″ panel. The LM270WR8-SSE1 will offer a 4 side borderless design, 3840 x 2160 “4K” resolution, 144Hz refresh rate, 99.5% DCI-P3 colour gamut (92% Adobe RGB, 99% sRGB also) and a Mini LED backlight with (we believe) 1560 zones capable of supporting the HDR 1000 standard.

The specs we had last time suggest this panel has a typical SDR brightness of 500 cd/m2 but a peak brightness for HDR of 1250 cd/m2. Other expected specs include a 4ms G2G response time (listed as “without overdrive” interestingly), 1000:1 contrast ratio, 178/178 viewing angles, 8-bit+FRC colour depth.

This panel has been delayed a bit further, slipping from Q4 2022 to Q1 2023 and now also slipping further to Q3 2023.

24.5″ 1080p IPS panel with 480Hz

This was actually mentioned all the way back in our 2021 update, but it seems this is still not in mass production even now, although thankfully it looks like it will be soon. This is now listed for Q2 2023 mass production. It’s expected to have support for a 510Hz overclock, 4ms G2G response time and a standard sRGB colour gamut.

27″ 4K IPS panel with 240Hz refresh rate

This one is only in the planning stage at the moment, but pencilled in for H2 2024 is a new 4K resolution panel in 27″ size, offering a 240Hz refresh rate. Previously LG.Display’s 240Hz panel plans had maxed out at 1440p so it’s good to see the push to 4K in their plans.
