LCD Projectors
LCD Display Panels
LCD (Liquid Crystal Display) projectors are in many ways similar to DLP projectors,
and share many of the same advantages and disadvantages. Instead of
bouncing the image off a mirror, an LCD projector uses an “LCD slide” to
modulate the light. The more analog nature of this technology means some LCD
projectors may require more adjustment than DLP projectors, and exhibit less
long-term stability.
LCD projectors may also suffer from a poor black level. The problem may be
even more noticeable on LCD projectors than on DLP projectors, and there’s a
wider span of variation due to the large number of LCD chip manufacturers.
Apply the same precautions as for DLP projectors.
Modern LCD displays typically have very good color matching, brightness and
long-term stability – particularly when connected digitally. However, when
using multiple LCD displays to build larger display areas, bear in mind the
often limited viewing angle.
Most LCD displays are designed for optimal image quality when viewed from
the front, with image quality degrading drastically as you move off-center.
Often, the viewing angle is better when moving horizontally than when moving
vertically (as would be the case when placing multiple landscape-oriented LCD
displays in a column).
