While LG and Samsung trumpet their OLED prototypes, Sony has apparently moved on from the tech, choosing to highlight a new 55-inch Crystal LED prototype at CES 2012. Its display relies on "ultrafine" LEDs mounted to each RGB color, equivalent to the number of pixels, which is all affixed directly to the front of the display. We don't have the full details, but so far Sony is claiming 3.5 times contrast, 1.4 times the color gamut and 10 times faster response time than LCDs.
Update: We've seen it in person and we can certainly say it was both bright and beautiful, however it was only displaying still images at a frustratingly slow refresh rate. In other words, it was a prototype, but one we'd love to watch some real videos on some time soon.

Sony Develops Next-generation Display, "Crystal LED Display" Ideal for High Picture Quality on Large screens
Full HD 55-inch Prototype model Exhibited at 2012 International CES
Tokyo, Japan – January 10, 2012 – Sony Corporation ("Sony") today announced that it has developed the next-generation self-emitting display, "Crystal LED Display," and presents a Full HD, 55-inch prototype model at the '2012 International CES' (International Consumer Electronics Show held in Las Vegas, Nevada, from January 10 - 13, 2012). It is the industry's first 55-inch Full HD self-emitting display using LEDs as the light source.
The "Crystal LED Display" is a self-emitting display that uses Sony's unique methods to mount ultrafine LEDs in each of the Red-Green-Blue (RGB) colors, equivalent to the number of pixels (approximately six-million LEDs for Full HD). The RGB LED light source is mounted directly on the front of the display, dramatically improving the light use efficiency. This results in images with strikingly higher contrast (in both light and dark environments), wider color gamut, superb video image response time, and wider viewing angles when compared to existing LCD and plasma displays, with low power consumption. Furthermore, due to the display's structure, the "Crystal LED Display" is also ideal for large screens.
Compared to existing LCD displays, the 55-inch prototype exhibited at CES is boasting approximately 3.5 times*1 higher contrast in light environment, approximately 1.4 times wider color gamut, and approximately 10 times faster video image response time (all values based on current Sony models). Sony envisages a wide range of applications for its "Crystal LED Display", ranging from professional to consumer use. Parallel to its continued development and commercialization of organic light emitting diode (OLED) displays, Sony will work conscientiously to bring the "Crystal LED Display" to market.
