One of the key advantages of OLED in digital signage (and it has only a few) is flexibility. LG showed concave and convex displays in 65″ and with UltraHD resolution. The concave display was a very tight 500R which made the single display very immersive, while the concave version was 1500R. Colour gamut is the same as the dual sided version, but brightness was better at 450 cd/m² at 25% (150 cd/m² at 100%).

Samsung has started mass production of its large transparent OLED, so it was no surprise to see LG getting into this segment. The panel was a 55″ with 40% transparency, but staff told us that mass production could be as far away as December 2018. (We wondered how LG was making this panel, as a standard OLED, using LG’s white OLED with colour filter could not achieve this level of transparency, but we were unable to get more info.)
In the middle of the meeting room, LG had set up a set of “dual view” curved OLED displays, that were curved into “S” shapes to show the flexibility of the OLED technology (see image)
In the TV side, the ArtSlim concept is still being developed and a 65″ version, which just needs the electronics added, was show. There was also an 8K M+ RGBW display with 700 cd/m² of brightness and 90% of DCI P3. LGD told us that it is working to ensure that the same SoC could be used for 4K and 8K panels. Staff told us that the 8K M+ panel would ship “soon”.
Although most of the emphasis was on OLED, LGD did show some LCDs. A 65″ UltraHD using the M+ technology boasted peak brightness of 1,500 cd/m² (typical 1,000 cd/m²) and with 133% of sRGB and 95% of DCI P3. The direct view LED backlight is segmented into 170 zones and the refresh rate is 240Hz.
Finally, we had a quick look at an 86″ “Ultra Stretch” display (left). No further information was being revealed, but we’ll follow up at ISE. The aspect ratio was said to be 58:9.
We were focused on collecting the data at the show, so we didn’t get much in the way of video. This video from mobilegeeks.de caught some good footage of the flexible and transparent displays at the show. http://tinyurl.com/hmvys2g
