For the last couple of years, LG Display has shown a 65-inch rollable OLED-TV screen in its analyst/media/customer suite at CES. This year, LG Electronics introduced the LG Signature OLED TV R rollable television set with high-voltage fanfare (Fig. 1).
The set is a 65-inch, 4K, OLED TV whose screen rises from a slot in its oblong base. The set can operate in different modes with different screen heights protruding from the base.
At LG’s press event held at the Mandalay Bay on the Monday of CES Week, LG showed videos of the OLED TV Rs in multi-million-dollar apartments with window walls and magnificient views — views you would not want to block with a conventional high-end TV screen (Fig. 2). On the evidence of these videos, LGE sees the market for these TVs as the Mar-a-Lago social set. On the show floor, LGE had five of the roll-up sets continually going up and down, and they drew a self-refreshing crowd (Fig. 3).
But, although LGE was giving the OLED TV R what looked like a major product roll-out, it’s unlikely the set will be available before the end of the year, if then. Pricing was also not released (although an LG Display representative said to me that it will be expensive – Man. Ed.) An LGD person said LGE intends to wait and see how Samsung responds. I don’t understand that because Samsung does not have a flexible, large-screen technology to respond with.
Samsung dominates the market for flexible RGB OLEDs for smartphones, but they do not have the display technology or manufacturing facillities needed to make TV-sized flexible displays at an acceptable cost. Samsung has announced it is working on QD OLED, which would use blue OLED layer with red and green quantum-dot color convertors.
At first look, it doesn’t seem reasonable to base a display technology on the least efficient and shortest-lived of the OLED emitters. But let’s start from a different starting point: LG’s “color by white” OLED technology. LG deposits unpatterned “white OLED,” which is a combination of blue and yellow OLED, which together make “white.” The light passes through an RGB matrix color filter much like the filters commonly used in LCDs.
