samsung 200hz technology

Samsung LCD TVs weren't the first to offer 200-hertz technology - this honor goes to the manufacturer's panel-production partner, Sony - but Samsung is hard on Sony's heels. The technology is intended to eliminate the weaknesses of older LCD TVs - in particular, the frequent motion blur. Besides top electronics, however, the TVs also need fast, responsive panels. Compared to older models, current liquid-crystal displays switch much more quickly from light to dark - and back. Without this added speed, the so-called "Motion Plus" technology would be totally ineffective.

200 Hz Motion Plus generates 200 images per second, which is no easy task - TV channels (or DVD players) only deliver 25 per second. And, to complicate matters further, these 25 images appear not intact but, rather, split up into 50 "interlaced" images. To put it more clearly: A TV camera records images in horizontal lines. First, it records the uneven-numbered lines - first, third, fifth, and so on. These form the first interlaced image. The second interlaced image then consists of all the even-numbered lines - 2, 4, 6, and so on. One 50th of a second elapses between the recording of these two images, meaning a rolling football, for example, will be in a different position in the two images. This "interlacing" method of capturing images causes no bother on tube-based TVs.
