Samsung has been working on all manner of screens and LCD tech for a long time. The company is one of the world's largest producers or LCD panels and those panels make their way into many other brands of TVs and computers.
Samsung has unveiled the world's largest transparen't AMOLED screen. The screen is 19-inches and you can see through the image and the screen to what is behind it.
This would be cool tech for future car windshields where you could put information on the windows and the driver could still see. I don't see the tech being big in the TV market where it would cause problems with image quality.
