Sony Intros 55-Inch Crystal LED Display Using 6 Million LEDs

By - Source: Sony | B 38 comments

Sony has developed a new Full HD display using six million LEDs and measuring 55-inches.

On Tuesday Sony said that it has developed the industry's first 55-inch Full HD self-emitting display using LEDs as the light source. Called the Crystal LED Display, it uses Sony’s "unique methods" to mount ultrafine LEDs in each of the Red-Green-Blue (RGB) colors, equivalent to the number of pixels -- meaning the company uses approximately six-million LEDs to create a Full HD display.

"The RGB LED light source is mounted directly on the front of the display, dramatically improving the light use efficiency," Sony said. "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."

Sony is currently showing a prototype display at CES 2012 in Las Vegas. It has a brightness of approximately 400 cd/m², a viewing angle of approximately 180 degrees, and a contrast of "more than measurable limit values." The color gamut is also "more than 100-percent compared to NTSC (xy)." When compared to existing LCD displays from Sony, the prototype boasts approximately 3.5 times higher contrast in light environment, approximately 1.4 times wider color gamut, and approximately 10 times faster video image response time.

Sony said it will "work conscientiously" to bring the Crystal LED Display to market while also continuing development and commercialization of organic light emitting diode (OLED) displays.

    This is what I thought current "LED" TVs were when they first came out. I was disappointed to find out that they were just referring to the backlighting.

    It sounds incredibly expensive to manufacture, but it must look amazing.

    so how does this compare to OLED?

    Isn't Sony also fond of claiming infinite contrast ratios by turning the screen off completely to get their black value? I'm sure this screen is awesome, but I really don't trust Sony on their contrast ratio claims any more.

    Hopefully unlike OLED oxygen doesn't kill it and also hopefully it has a life cycle longer than 7 years.

    I'm interested in this, as well as knowing how much power draw is behind 6 million LEDs on a mostly white screen.

    willard, the whole point of LED backlighting is to get deep blacks by turning backlighting off, as opposed to CCFL backlighting that is always on. it's not just sony that can erroneously brag about contrast ratios on their LED TVs, it's everyone who makes LED TVs.

    with that said, i understand the benefits of having the pixels themselves light up and negating backlighting altogether. it would actually improve contrast ratios, energy efficiency, and (i imagine) eliminate the "ghosting" effect current LED TVs suffer from while still maintaining the ability to deliver truly deep blacks.

    i'd like to know pricing and availability on these TVs, i'll be in the market for a new HDTV in a year or two.

    The example picture of the screen is pretty absurd, I mean, If it looks great, then the only reason is cuz my current screen got great colors.....

    Normally I would agree with you, as I am NOT a fan of dynamic contrast screens. Turning off sections of back lighting to boost contrast numbers does not increase the quality of the picture, and it creates halo effects when areas of light are surrounded by dark picture. It looks worse than when the dynamic lighting is disabled, in my opinion.

    However, in this case, I think the dynamic back lighting has real potential and the inflated numbers may finally be accurate. This screen would no longer be manipulating the back lighting for sections of the picture, but for each individual color of each individual pixel. This potentially puts the LCD picture on par, if not ahead, with what modern plasma screens are capable of, with much lower power use and waste heat.

    I'm looking forward to this making its way into the mainstream. It's a technology approach that I always dreamed would happen but never dared to hope for.

    Organic LEDs are based on organic compounds which may or may not have metals and, like devilzzz2007 pointed out, they break down over time (not to oxygen though these are sealed in a vacuum) due to electrical current and the resulting heat. these leds are more likely made of metals and metal compounds with nitrogen or various metalloids.

    so what will manufacturers mislabel this as? we already have "led tvs" which are really "lcd tv backlit by led"... if this was called "led tv" it would lead to even more mass market confusion.

    i'm all for this type of technology. this is definitely a step forward.

    you know what would be awesome, get a dslr camera and set it to a 2ms exposure time, and let people take picutres of a ball going back and forth, so we aren't lied to about its repose time so blatantly.

    every number on a tv besides its size is a lie.

    "wider viewing angles when compared to existing LCD and plasma displays"????

    Thought plasmas had NO limit on viewing angle, neither of mine seem to, that's for sure.

    Also, I just love how everyone thinks LED isn't LCD. At Walmart the other day listening to a "sales person" telling an older couple how LED is soooo much better than LCD, then the old guy said "Why does the box say LED LCD?" Dude was like "uh, that box is probably used for two different tv's" I was about to go smack him upside the head.

    Sony is losing out in sales still with HDTV's because it still pricing them based off a reputation they still think they have. Sony isn't the king of the hill and no one pays more for thier name as much anymore.

    I'll stick with my LG's.

    Contrast on AMOLEDs (the only variation of OLED in production I guess) was said to have LOWER contrast than conventional LCD.

    On the first read through of the first like I though it meant 6 million 55" LED's and the first thought was "Oh my God that is huge!" followed by "That can't be right... were's my coffee...."

    This will not be a cost competitive TV any time soon and as with all tech, what it can do and what the medium such as cable/DVD/Blue Ray can actually output are 2 different things.

    I wonder what the "dead pixel" policy will be on this.

    a contrast of "more than measurable limit values."

    Does this mean when you turn on the T.V. you could watch it through the walls of your house or that your house will be a beacon to space ships?

    Brandenwillard, the whole point of LED backlighting is to get deep blacks by turning backlighting off, as opposed to CCFL backlighting that is always on.

    In reality only the highest end LED TV's use local dimming, most of them are edge lit displays that stay on at all times. And like shoreless pointed out, the local dimming displays suffer from some pretty wonkey problems, so they are best avoided. OLED and true LED are the way to go as you get super high contrast like a plasma screen, but without the power bill or burn in issues.
