LG Display showcased several of its OLED technologies at SID DisplayWeek. The most impressive display was a 77" panel that is both flexible and transparent. The large panel features a 4K (3840x2160) resolution and 40% transmittance. The bending radius of the display is 80 mm. This seems to be the same display announced in June 2017.
LGD also demonstrated, for the first time, its VR OLED display, developed in collaboration with Google. This is a 4.3" 3840x4800 (1443 PPI) glass-based display on an LTPS backplane, that supports a refresh rate of 120Hz.
Finally LGD also demonstrated its crystal-sound OLED, which was already used commercially by Sony in its 2017 XBR-A1E OLED TV.
It was disappointing to see that LGD did not showcase many of its innovative OLED displays and products - its 88" 8K OLED TV, the rollable 65" OLED TV, the transparent and curved commercial OLED panels and of course its commercial OLED TVs and mobile phone displays that are now in production.
It seems that more and more companies, LG included, prefers to showcase some of their display technologies at CES and not at SID.
