Sony shows 55-inch prototype using new "Crystal LED Display" technology

While OLED may have staked a claim as the next generation display technology to beat, Sony has chosen CES 2012 to unveil a new display technology called "Crystal LED." Instead of an LED or CCFL backlight shining through an LCD layer to produce an image, the Crystal LED display technology is a true LED TV that uses a layer of tiny self-emitting LEDs to directly produce the image - think of it like a high resolution shrunk down JumboTron like those found at sporting stadiums.
With each pixel in the 1080 x 1920 Full HD resolution display made up of a red, green and blue LED, the 55-inch prototype model on display at CES uses over six million individual LEDs to create an image. Sony says mounting the LED light source directly on the front of the display results in greater light use efficiency and produces higher contrast images in both light and dark viewing conditions. It also produces a wider color gamut and wider viewing angles compared to existing LCD and plasma displays.
In fact, the display's technical specifications list a brightness of approx. 400 cd/m2, a color gamut of more than 100 percent compared to NTSC, a viewing angle of 180 degrees, and a contrast in dark environments that is "more than measurable limit values." Additionally, Sony says the prototype display has a video response time that is 10 times faster than its current LCD models.
While the Japanese electronics giant says it will continue development of OLED TVs, it will be working in parallel to develop and commercialize its new Crystal LED Display technology with an eye on both professional and consumer products.
Here's a video from Sony detailing the new technology - somewhat embarrassingly, the audio cuts out half way through.
