Intel Pushes Into Home Entertainment

Liquid crystal on silicon for rear-projection HDTV is part of consumer-focused plan

4 min read

21 January 2004--Drawing on its expertise in making silicon chips, Intel Corp., in Santa Clara, Calif., is moving beyond the world of PCs into home entertainment with a chip it says will dramatically reduce the cost of big-screen televisions. The company announced at the International Consumer Electronics Show (CES) in Las Vegas, Nev., in January that it will start selling liquid crystal on silicon (LCOS) chips later this year. The LCOS chips will be used to create microdisplays for rear-projection TVs, allowing manufacturers to sell 50-inch high-definition television sets for less than US $1800. "This will change big-screen television economics," Intel president Paul Otellini told a CES audience.

Currently, big-screen TVs cost anywhere from $3000 to $8000. Of the rear-projection TV models, between 80 and 90 percent use cathode-ray tube technology, says David Mentley, senior vice president of analyst firm iSuppli/Stanford Resource, in Santa Clara, Calif., a technology that he believes could be used to make a big-TV screen for as little as $1200, although the quality would not be as good as that of LCOS models.

Digging Into the New QD-OLED TVs

Formerly rival technologies have come together in Samsung displays

Sony's A95K televisions incorporate Samsung's new QD-OLED display technology.

Televisions and computer monitors with QD-OLED displays are now on store shelves. The image quality is—as expected—impressive, with amazing black levels, wide viewing angles, a broad color gamut, and high brightness. The products include:

All these products use display panels manufactured by Samsung but have their own unique display assembly, operating system, and electronics.

I took apart a 55-inch Samsung S95B to learn just how these new displays are put together (destroying it in the process). I found an extremely thin OLED backplane that generates blue light with an equally thin QD color-converting structure that completes the optical stack. I used a UV light source, a microscope, and a spectrometer to learn a lot about how these displays work.
