Produces very bright images due to high peak intensity.
Very suitable for environments that are brightly lit
considerably lower electric, magnetic and electromagnetic
fields than CRTs.
geometric distortion at the native resolution. Minor
distortion can occur for other resolutions.
efficient. Consume less than 1/3 the power of a comparable
CRT. Consume less electricity than a CRT and produce
up about 40% less desk space. LCDs are thin and compact.
the native resolution, the image is perfectly sharp.
Adjustments are required at all other resolutions
which can result in measurable degradation to the
aspect ratio and resolution are fixed.
proficient at producing black and very dark grays.
In a "standard" configuration, not appropriate
for use in dimly lit and dark conditions.
contrast than CRTs due to a poor black-level.
and Gray-Scale Accuracy
Color saturation is reduced at low intensity levels
due to a poor black-level. Images are satisfactory,
but not accurate due to problems with black-level,
gray-scale and Gamma.
more expensive purchase price than comparable CRTs
. (Cheaper lifetime cost: lasts about 13,000 - 15,000
more hours than a typical CRT.)
an irregular intensity scale and typically produce
fewer than 256 discrete intensity levels. For some
LCDs portions of the gray-scale may be dithered.
response times and scan rate conversion result in
severe motion artifacts and image degradation for
moving or rapidly changing images.
best at the native resolution. The native resolution
can not be changed. All other resolutions require
adjusting procedures which can cause considerable
deterioration of the image.
viewing angles. Viewing angles affect the brightness,
contrast and colors shown. Wide angles can lead to
contrast and color reversal.
Saturation and compression can occur due to the bright-end
of the intensity scale becoming overloaded. Contrast
control must be carefully adjusted.
have many weak or stuck pixels, which are permanently
on or off. Some pixels may be improperly connected
to adjoining pixels, rows or columns.
require frequent readjustments throughout the day
due to timing drift and jitter. Analog input requires
careful modification of pixel tracking / phase to
decrease or eliminate digital noise in the image.
