LCDs are a crucial component of 3LCD systems and are the reason that 3LCD got its name, but no, the two technologies are not the same. Here is an overview of both technologies and how they relate to each other.
What is LCD?
LCD standard for Liquid Crystal Display.
A very popular display technology, you find LCDs all around you, in
digital clocks, MP3 players, and watches, just to name a few. LCDs are
very common because they offer distinct advantages: they are thinner,
lighter, and draw less power than many competing technologies
One key feature of LCDs is that applying an electric current controls the way light passes through the display.
The simplest version of this effect is seen in digital watches where
numbers are created by the display not allowing light to pass through
in the shape of each number. Over the years, Epson has built upon this
basic technology and developed LCDs that display millions of colors.
These sophisticated LCDs are used in televisions and projectors, where subtle and precise color differences create the beautiful images you see.
What is 3LCD?
In developing LCD technology, Epson discovered that using a combination of three LCDs to produce a final image was the optimal way to achieve the sharpest and most beautiful images
in televisions and projectors. Since this trio of LCDs is a unique
technology used in projecting images, it was important to differentiate
this innovation from the hundreds of other uses for single LCDs. Thus the name 3LCD was born.
projection systems give you dazzling brightness, true-to-life color
saturation, and razor-sharp contrast for displaying digital content. This robust technology is incredibly versatile and is used in a variety of applications. For example, 3LCD easily displays full high-definition television (HDTV) broadcast signals. With the increasing popularity of HDTV, 3LCD's versatility confirms its top position in the video projection market.
