What is the Difference Between Full HD & LCD HD?
When it comes to HD (High Definition) television, a potential HDTV customer will encounter a variety of marketing terminology that can lead to confusion. “LCD HD” indicates a type of flat-panel display, while “Full HD” indicates the quality of an HD signal.
To qualify as “high definition,” the image must be at least 1280 x 720 pixels. This is known as “720p,” where the “p” refers to progressive scan, a display method that refreshes the screen all at once for more fluid motion.
720p and 1080p
The next step up from 720p is 1080p, which is 1920 x 1080 pixels, progressively scanned. 1080p is the highest-quality of HD signal, so it is sometimes referred to as “full HD”-the “fullest” form of HD you can have.
LCD refers to Liquid Crystal Display. This is one type of flat-panel display technology. Others are plasma, DLP (Digital Light Processing) and LCoS (Liquid Crystal on Silicon).
Therefore, “LCD HD” refers to a liquid crystal display that is capable of at least 720p. Such a display is not necessarily capable of 1080p.
1080i can also be “full HD,” since the term refers to image resolution and not necessarily the scan method. The “i” stands for “interlaced.” While progressive scan refreshes the screen all at once, interlaced scan refreshes every other horizontal line on the screen.
