Today at CES Samsung unveiled a new 55" curved OLED TV prototype. According to Samsung, a curved TV provides depth to the image and so enables a more life-like viewing experience. This is especially true for panorama landscapes and nature scenes, they say you'll feel surrounded by the beautiful scenery.
This is just a prototype, probably nowhere near production, and Samsung wouldn't reveal any technical details. Unlike Samsung's Nexus S phone which used a regular OLED and curved glass, this seems to be an actually curved flexible OLED panel, at least from the photos.
Obviously making a flexible OLED like that is not easy. Samsung is still struggling with their small flexible OLEDs (having delayed production to 2013). But it's good to see them manage to produce even just one flexible panel so large...
Interestingly, back in 2010 Samsung showed a flexible 3D OLED TV concept, which was an idea from their design-your-display contest. The concept TV was foldable - so you can get optimum 3D images from anywhere in the room. The real prototype they are showing now isn't foldable of course, but it's nice to see Samsung actually delivering (at least partly) on that idea from two years ago).
Back in October 2008 Sony showed their own curved OLED TV prototype. While it was much smaller in size (11"), the width of Sony's panel was only 0.3 mm, which is very impressive.
