HDTV and Home Theater Podcast - Podcast #522: Crystal LED HDTV Technology

Today’s Show:

Crystal LED HDTV Technology

It was pretty clear that the OLED TVs demonstrated by LG and Samsung stole the show at the last Consumer Electronics Show we went to. We were really impressed by the color, contrast and sharpness of the picture. Check out this video we shot in the Samsung booth (Samsung Super OLED HDTV). However, there are some issues that need to be resolved before we see mainstream OLED HDTVs in sizes that we would want in our living rooms.

Rather than go with an OLED TV, Sony displayed a technology called Crystal LED. Crystal LED takes six million tiny LEDs to create a picture that they hope will rival OLED technology. A 1080P TV has nearly 2 million pixels on screen. Crystal LEDs TVs take three LEDs, one for red, green, and blue, and combine them for each pixel. Each pixel is mounted directly in front of the display. This is not an LED based LCD but an actual LED TV.

On paper this technology has a ton of potential. For instance, like plasma, each individual pixel can be controlled. This should provided blacks that can rival plasma and OLED. Another benefit for the technology is that a Crystal LED will use far less energy, 70 watts for a 55 inch screen. Crystal LED TVs produces a picture with viewing angles of 180 degrees, high contrast ratios, and better color than current plasma and LCD HDTVs.

The version that we saw in Las Vegas looked quite impressive. One of the things that stuck us was that there was minimal reflection. That is another drawback of plasmas. We left the Sony booth thinking we could have our cake and eat it too!.

The concept isn’t new. Those really large screens that you see at stadiums use this type of technology to do the same thing. Its much easier to do this on a large screen when you are sitting tens or hundreds of meters away. The key for Sony is that they are shrinking the size of the LEDs down dramatically so that they can fit six million of them into a screen that would fit in your family room. That process is complex and costly. Sony wants to get this right. With six million LEDs there will be a higher chance of having a dead pixel.

Cost and Availability

So when can I have one and how much will it cost? Sony isn’t answering any of these questions. Our hunch is that it will cost about what an OLED TV will cost. And if Sony wants this technology to have a chance it needs to come out at about the same time as OLED. We know that Samsung will be releasing their OLEDs in the second half of the year. Our prediction is that you will be able to by a Crystal LED TV from Sony by the summer of 2013 and it will run about $6,000.

Hi guys - sorry to burst your bubble, but the models you saw were wire-bonded with over 6 million connections In other words, these I-LED TVs were hand-built prototypes and WAY too expensive to manufacture for the retail space. You are not likely to see them any time soon - they were just a technology concept exhibit.

This information provided from sources in Japan who are more familiar with the design and assembly of these TVs.

So for now, the Samsung and LG 55-inch OLEDs will have a substantial head start both in terms of time and cost....
