Cool concept and commercial OLEDs and LCDs from LG Display

The private booth of LG Display was home to some of the strangest and coolest TVs at the 2017 CES. Let's take a closer look.

Shown here: A display that actually creates sound I heard as well as felt.

Here's a video wall composed of three OLED displays in portrait orientation.

OLEDs can have extremely thin borders around the edges for a more seamless look.

A display shows all of the "layers" that go into an LCD TV.

In comparison OLED can be extremely thin. The "wallpaper" design is between 2 and 4mm thick.

Yep, pretty thin.

Did I mention it was thin?

77 inches of OLED hugeness.

The ribbon cable that connects the "wallpaper" OLED display to the box that houses inputs, the power supply and other necessaries.

This demo showed a new use case for OLED LG called "Crystal Sound." I could hear as well as feel the music coming from the screen itself.

It was strong enough to actually bounce these small plastic beads.

The sound is delivered by transducers like this behind the screen -- in effect, the whole screen behaves as a speaker. The best part is that Sony is actually bringing the technology to market this year in its A1E OLED TV.

Here's a 77-inch OLED set back-to-back with another on a rotating stand in portrait mode. The idea? Life-size models, the better to practice your forehand.

Yep, these are thin, too.

Transparent OLED lets high-end digital signage get the message across with more clarity.

Objects like these flowers behind the screen actually show through.

Here we find a column wrapped in six 77-inch OLEDs in landscape mode curved convex.

It's pretty amazing in person. This image doesn't really convey it, but the video helps.

In addition to OLEDs, LGD also makes scads of LCD displays. Surrounding a 4x4 video wall are some unusual ultra-wide aspect ratios for digital signage.

LGD says its new IPS-based LCDs are better.

"Nano color" appearing in 2017 Super UHD LCD TVs is the company's answer to Samsung's quantum dots.

They tout an even wider viewing angle than before. No mention was made of improving black level, IPS' biggest weakness.

LG also touts improved light output in its LCDs, to better reproduce HDR.

No tour of concept displays is complete without an 8K display. At 65 inches, individual pixels are basically invisible.

I'll talk to you after I'm done counting all 33,177,600 of them. While you wait, check out my post-show report for more on CES 2017's TV news.
