Wide color gamut
Barco's RHDM-family has
RGB-LED backlights
with separate red, green and blue
LEDs. This results in a wide color gamut (wider than required for Rec.709). This color
gamut is then transformed to the required display gamut (e.g. Rec.709, SMPTE, EBU).
Worry-free auto-calibration
To counteract the effects of ambient temperature and backlight aging, the RHDM
series have
integrated calibration and stabilization technology
, including a spec-
trometer, various color sensors and temperature sensors. This means that the
displays’ colors and white point are constantly monitored and corrected in real time in
case of imperfections. What’s more, there is no need to recalibrate the monitors for at
least a one-year period.
Via an easy user interface, the embedded spectrometer enables manual control of the
display white point in actual (x,y) coordinates. In the RHDM-P versions, also the pri-
maries can be adjusted so that film post-production users can benefit from the large
LED gamut. The white point balancing is directly performed on the backlight. Unlike
typical R-G-B gain controls in traditional monitors, the contrast is preserved and no
display levels are discarded. Manual calibration is as simple as typing in the required
white-point color coordinates, for example those measured on a CRT.
Motion blur prevention
Traditional LCD monitors present blur artifacts as a result of the deinterlacing mode,
which typically builds up the image in a line by line drawing process. Barco's RHDM
series counteract this by
reducing the ‘hold’ effect
created by LCDs. First of all, the
monitors have a fast
120Hz panel
. In addition, the RHDM series’
scanning backlight
system
makes sure that only the stable LCD information is illuminated.
Finally, to avoid the typical de-interlacing artifacts, the RHDM-family also allows for
black line insertion
for
native interlaced representation
. In practice, this means
that each field of interlaced video (odd and even) is displayed separately and the cor-
responding second fields are blanked with black lines.
