CES 2012: Sony Pulls “Crystal” Display Technology Out Of the Lab

Has Sony ceded OLED to Korean companies? Is “Crystal” an alias for “Quantum-Dot”?

CES 2012: Sony Pulls “Crystal” Display Technology Out Of the Lab

For several years, Sony has pointed to its small, expensive, but definitely gorgeous OLED (Organic Light Emitting Diode) television displays as the future of television technology.

At this year’s Consumer Electronics Show in Las Vegas, Nevada, it indeed seems that the OLED future has arrived, with 55-inch OLED televisions from Korean companies Samsung and LG drawing huge crowds. One place you won’t find an OLED television this year, however, is in the Sony booth.

Likely, Sony simply isn’t ready to produce 55-inch OLED TVs, and the smaller models of previous years would look a little silly with giant OLED models just down a couple of aisles.

Instead, the “future” section of Sony’s booth features a 55-inch prototype of a technology that it calls “Crystal”. A Sony representative explained that the technology uses “RGB LEDs”, that is, each pixel is made up of 3 individual LEDs—6 million all together, manufactured on a single substrate, that presses right up against the glass for maximum brightness. That’s about all the technical details he would give, and he was careful to point out that it is indeed just a technology at this point, one of several advanced technologies being explored for advanced displays, and, while Sony thinks it has more potential than OLED, it isn’t abandoning that technology.

But what exactly are “RGB LEDs?” Could they—and bear with my while I go out on a limb here—be quantum dot technology? Sony is one of several companies believed to have been working on this technology into displays—is Crystal the first demonstration?

If anybody knows for sure, please comment here, or tweet direct @TeklaPerry on Twitter.

The century-old quest for truly realistic sound production is finally paying off

Now that recorded sound has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it’s an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week.

Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison’s phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
