Coming Soon: Trillion-Color TV

Technology promises to bring the color of cinema to home TV sets

3 min read

You sink into the couch and start to play a DVD on your big-screen TV set, ready for some cinema-quality entertainment in the comfort of your home. But something is missing, even if you might not notice it, and it's not the gigantic popcorn bucket. It's real color, says Genoa Color Technologies Ltd., an Israeli company in Herzlia Pituach.

While film used in cinema contains pigments that can create an infinitely large number of color variations, TV sets combine discrete amounts of red, green, and blue light to create a much more limited color range. To produce more colors, TV sets would have to combine purer, or more saturated, red, green, and blue by using narrowband light filters that select colors more precisely but diminish brightness at the same time.

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.
