HDTV and Multimedia Display Technology Shoot-Out
Comparing CRT, LCD, Plasma, DLP, and LCoS Display Technologies
|
This set of articles provides in-depth comparisons, analysis and evaluations
of CRT, LCD, Plasma, DLP, and LCoS display technologies
for HDTV and Multimedia displays,
including computer monitors, projectors and mobile displays
where picture quality and color and gray-scale accuracy are important.
They are based on in-depth laboratory measurements and
scientific analysis using the
DisplayMate Multimedia Editions
with a Spectroradiometer.
The articles are written by
DisplayMate Technologies President,
Dr. Raymond Soneira.
They have been translated and published in over two dozen consumer video,
computer, Professional Audio-Video, and Research publications worldwide.
Most manufacturers use seat-of-the-pants ad-hoc display design, tweaking and calibration methods with below par results
DisplayMate Technologies
specializes in sophisticated mathematical display
optimization and advanced scientific display calibration
to deliver unsurpassed image and picture quality and accuracy
that is guaranteed to out-perform all
traditional ad-hoc calibration methods.
These articles are a lite introductory analysis for general audiences.
Our proprietary display optimization technology corrects these deficiencies and much more.
