Sony showed off a new television technology called Crystal LED, which is literally every pixel is a RGB LED pixel, has better contrast and a lower power consumption.
You can check out a YouTube video, or more from sony at CES at their blog.
Looks like this tech is a bit in the future, but sounds very cool, and I have seen described as between plasma and lcd. Personally deeper black is very exciting, and with individual led’s it should have pretty good color fidelity.
Now I just wonder how expensive it will be.
