Samsung Display was tucked away in a meeting room and was talking to its clients and specifiers for LFDs. As we went into the booth, we were met by the four way 55″ transparent OLED video wall that we saw at CES. Once again, photos were banned. However, we were able to clarify one point. The OLEDs have 30% transparency at the moment, but will be 40% by the time that production volumes of panels become available in Q4. By next year, the plan is to get to 50%. There will be a 65″ version as well as the 55″, later. An interesting point about the OLEDs is that a camera placed very close to the display can take a picture through the OLED panel.
A second variation that was not seen at CES was a very impressive mirror display. When the OLED was powered down, the mirror looked just like a regular mirror, but when the OLED was on, data was overlaid on the reflective image. Once again, we were not allowed to take pictures, sadly, but the visual effect was very impressive and staff told us that reflectivity of the mirror is 82%, which is only just below a standard mirror. An interesting comment is that touch is not a good application for mirror displays because of the problems from finger marks. In prestige stores, screens would have to be cleaned every hour.
There was an area of the suite that was devoted to new LED backlights. The LEDs have diffusing lenses so that direct backlights can be much more even and fewer LEDs can be used. 
Samsung is also bringing back the 21.6″ square display which it featured a couple of years ago, but then dropped in production. There were also new “bar type” of 43″ and 49″ (cut from a 55″). The new bars have thinner bezels than previous versions.
Samsung was also highlighting its 2,500 cd/m² LCDs with 46″, 55″ and 75″ options. There was also a 75″ FullHD “EBoard” display (with UltraHD an option).
