Keys to Projector Color, LCD vs DLP vs LCoS
In years past, the hands down favorite for accurate color representation has been LCD. However, DLP technology has improved significantly over the past five years, especially with the breakthrough of Brilliant Color technology, which includes an expanded color wheel featuring CMY colors along with RGB.
Still, LCD technology is generally considered to display the most accurate colors. DLP projectors will create slightly softer images, with richer color and deeper blacks. LCD color will appear more true to life, with natural skin tones and more correct greens, blues, and particularly yellows.
DLP offers better contrast ratios and less space between pixels (nicknamed the screen door effect). A few individuals report seeing “rainbows” with DLP projectors. To some, these prisms can be very distracting. Most people do not notice this color artifacting.
The newest player in the display game is LCos. Remember, LCD is a transmissive technology whereas DLP is reflective. LCoS, in very simple terms, is a combination of the two – an LCD panel on a mirror.
The amount of pixels is less restricted than LCD or DLP because the electronics can be placed under the pixel rather than next to it. This high pixel density means high resolution. It eliminates flickering, the ‘screen door’ effect and ‘rainbows,’ and provides an overall higher picture quality on moving images. Because of this, many viewers say LCoS projects the most film-like image. Look for this technology in Canon projectors.
