Faithful Color Reproduction Meets Broadcasting Needs
[2550] [1760] [1710]
The BT-LH2550/BT-LH1760/
BT-LH1710 features a new
image processing engine.
By using a three-dimensional
LUT (Look Up Table) for each
RGB color and applying
precise 10-bit image
processing, it achieves
faithful color reproduction
from low to high brightness
levels in all video formats.
* SMPTE-C in North America.
I/P Conversion Circuit for Motion Response
[2550] [1760] [1710] [80WU]
A circuit delay time (not including panel delay) of approximately
5 msec*
1
is achieved by incorporating an I/P converter circuit that
converts SD and HD interlace signals with high precision and
generates a progressive signal without causing field-length delay.
Minimizing the delay between the input signal and monitor output
enables the user to confirm footage without any incongruity.
*1: Differs slightly depending on the signal format.
Diagonal Line Compensation
[2550] [1760] [1710] [80WU]
Jagged noise on diagonal
lines in moving images is a
common problem. These LCD
monitors solve this by
detecting correlations in the
diagonal direction, resulting in
smooth, precise reproduction
of moving images.
Gamma Compensation for Each Monitor
[2550] [1760] [1710]
In order to make the LCD monitor suitable for professional
broadcasting applications, compensation is conducted for each
monitor in 256 discrete RGB steps, rated gamma properties
(g = 2.2) are reproduced, and gradation suitable for broadcasting is
achieved. Color temperature of 9300K/6500K/5600K; 3000K to
9300K can be selected with the variable setting.
Double-Speed Drive for Blur-Less Moving Images
[1760]
Moving images without any afterimage are achieved by driving at a
speed (120 Hz/100 Hz) that is twice the panel speed and inserting
a black frame of a certain level between frames. Unlike frame
creation methods, this system minimizes afterimages while
displaying images faithful to the input signal. This high-
performance, high-speed image display function is ideal for
broadcast applications.
High-Speed Response
[2550] [1760] [1710]
The biggest concern when receiving a video feed is response time
in the intermediate gradations. The BT-LH1760 uses double-speed
drive to achieve superb response over the entire image, enabling
the vivid image display without blurring. The BT-LH2550 and
BT-LH1710 feature an overdrive circuit to improve response in
intermediate gradations.
Wide Viewing Angle
[2550] [1760] [1710] [900A]
By using a high-intensity, high-contrast LCD panel, wide viewing
angle is achieved in all models. The BT-LH2550 has a 178°, and the
BT-LH1760/LH1710 has a 176° horizontal and vertical viewing
angle. The BT-LH900A also has a 170° horizontal and vertical
viewing angle. Easy viewing is ensured by reducing changes in
color due to the viewing angle.
HD/SD Multi-Format
[2550] [1760] [1710] [900A] [80WU]
Compatible with most HD and SD formats, Panasonic LCD
monitors are ideal for a wide range of applications in locations
around the world.
