From the images and videos we have, it also seems that the panel itself is rather small – around 30 or 40 inches – but maybe I am wrong as the only large-area transparent OLED panels ever demonstrated were 55″ in size (from both Samsung and LG Display).
It is highly unlikely that Panasonic produced this panel itself as the company stopped its large-area OLED TV development in 2013. It’s likely that Panasonic uses LGD made panels, as it does with its commercial OLED TVs.
According to reports, this is Panasonic’s 2nd gen transparent displays. The first generation displays were LCD (LED) based displays, but the company was not happy with the quality of the display and the low transparency. Changing to an OLED display resulted in better transparency and great images – virtually indistinguishable from non transparent TVs.
