The Panasonic BT-LH1850 LCD Monitor
offers high-end performance and functions for broadcasting use.
With features like the 3D-LUT Color Correction, the high-quality
image engine produces faithful color hues and smooth gradation,
together with quick-response motion images. It's also packed with
convenient broadcasting functions, like a waveform monitor for Y,
R, G and B signals, SDI closed caption display, and a RS-485 serial
remote. The new panel with an LED backlight provides remarkably low
power consumption and high cost-performance. This versatile monitor
meets a wide range of needs, from image production to broadcasting
and business use.

3D-LUT Color Correction Keeps
Colors Faithful Even at Low Luminance Level
The color space on LCD displays tends
to narrow when the luminance level drops, and it's often
accompanied by color phase shifts that cause colors to drift.
3D-LUT (Look Up Table) Color Correction on the LH Series LCD
monitors includes a look up table for each luminance level, and
applies 10 bit image processing to each RGB color to balance the
six coordinate poles of the three primary colors (RGB) and their
complementary colors (CMY). This solves the problem of color
drifting at low luminance levels, and keeps colors vividly
natural. |

·
6-Poles (RGB/CMY) Coordinate
Correction Produces Smooth Intermediate Colors
In addition to enhancing low luminance
areas, 3D-LUT Color Correction helps to produce finely nuanced
intermediate hues. Based on color measurements in the intermediate
color parts of the image, this function applies smooth correction
processing while balancing the six coordinates of the three primary
colors (RGB) and their complementary colors (CMY), resulting in
beautifully smooth gradation. It keeps the intermediate shades of
extremely fine colors vibrant and lifelike. |
| |
· Faithful Color Correction from the
3D-LUT
By using a three-dimensional LUT (Look Up Table) for each RGB color
and applying precise 10 bit image processing, faithful colors are
reproduced from low to high luminance levels and natural
intermediate colors are attained. (more information)
· I/P Conversion Circuit for Motion
Response
A circuit delay time (not including panel delay) of approximately 5
msec* is achieved by incorporating an I/P converter circuit that
converts SD and HD interlace signals with high precision to
generate progressive signals without causing field-length delay.
Minimizing the delay between the input signal and monitor output
enables the user to confirm footage without any incongruity.
* Differs slightly depending on the signal format. |
| |
· Diagonal Line Compensation
Jagged noise on diagonal lines in moving images is a common
problem. This LCD monitor solves this by detecting correlations in
the diagonal direction, resulting in smooth, precise reproduction
of moving images. |
 |
| |
· Broadcast Settings for
Gradation and Color Temperature
Individual RGB corrections are made on every monitor that is
shipped, to ensure that rated gamma properties (g = 2.2) are
reproduced, and gradation suitable for broadcasting is achieved. A
color temperature of 9300 K/6500 K/5600 K, or 3000 K to 9300 K, can
be selected with the variable setting.
· WFM (Y/R/G/B) Display
The built-in waveform monitoring function displays a waveform in a
sub-screen. The display signal can be selected from Y, R, G and
B.
· Vectorscope Display
All lines of the input signal via SDI are displayed as a
vectorscope, and can be positioned in any of the four corners of
the screen.
· Various Markers
Various markers can be displayed in both 16:9 and 4:3 aspect
ratios.
• Aspect Marker (16:9): 4:3, 13:9, 14:9, CNSCO2.39,
CNSCO2.35, 2:1 or VISTA, with background brightness control of
Black (0%), Half (50%) or Normal (100%).
• Safe Area Marker (16:9/4:3): 95%, 93%, 90%, 88%, 80% or VAR
(variable setting).
• Center Marker (16:9/4:3): ON/OFF. The center marker can be
displayed together with another marker, as shown in the example
right.
· Cross Hatch Overlay
A simple cross hatch overlay can be displayed to check the
tilt of the camera.
|
 |
· Pixel-to-Pixel Display
This function lets you display and confirm video pixels without any
resizing. When displaying 1080i/p, you can choose from five display
areas: center, right-top, rightbottom, left-top or left-bottom.
· Still Frame Display
A frame of video can easily be frozen and displayed as a still
image on the left side of the screen. This function can be used to
match a live camera with a frame of video shot at an earlier time
or with a different camera.
· Audio Level Meter
The color audio level meter displays the input level of embedded
audio (SDI, HDMI*) or analog audio.* The display mode can be
selected from 2-channel, 4-channel, 8-channel or OFF. It is also
equipped with reference point setting, peak hold and over-range
display functions.
* For HDMI or analog audio input, the level meter displays only two
channels. |
| |
· Time Code
Display
With HD SDI input, this function displays the value of the VITC,
LTC or UB time code.
· HV
Delay Display and Mono Mode
The HV Delay function that displays the video blanking period, and
the Mono mode that switches the display to black-and-white, can be
assigned to function keys for quick access.
· RS-485 Serial Remote
Up to 32 monitors connected in a loop-through configuration can
each be designated and controlled by a distinct ID number. TSL
commands allow text display (8 alphanumeric characters) and tally
indication. The monitors also support unique Panasonic commands
(equivalent to RS-232C).
· Calibration Function
The BT-LH1850 comes installed with software that allows it to be
calibrated without using a PC, by simply connecting a
manufacturer-designated display color analyzer and measurement
probe to the monitor.
* Konica Minolta CA-310 Display Color Analyzer with CA-PU32/PU35 or
CA-PSU32/ PSU35 Standard Measurement Probe. For more information
about the Konica Minolta calibration system, please see the
following website [KONICA MINOLTA]. |

· Cine-gamma and Black Mode
The BT-LH1850 is equipped with a cine-gamma (F-REC) compensation
function and serves as a monitor for the Varicam camera recorder.
The black mode also makes dark image areas in low-gradation scenes
easier to see. It helps to produce movies as well as film-like HD
programs and commercials.
· Function Keys
Each of the function keys on the front panel can be assigned a
function selected from various display and switchover functions to
enable one-touch display ON/OFF or mode change. These function
buttons speed up operation and customize the functions to
individual user needs.
· SDI, HDMI and DVI-I Inputs
Two SDI inputs (SDI1/SDI2) with an automatic HD/SD switching
function are provided as standard equipment. They support embedded
audio, and the channel for audio output to speakers and headphone
can be selected. The next-generation HD Link is featured to allow
high-quality digital connection of a wide range of digital HD
products with an HDMI terminal, such as BD/DVD players. Digital and
analog DVI-I (Single Link) input is also provided.
· Low Power Consumption and Mercury-Free Design Help
Protect the Environment
A thorough energy-saving design has achieved low power consumption
of only 22 W (with DC input), which is a 54% reduction from our
previous model (the BT-LH1710 (2009 model) / Power Consumption 48W
(DC IN)). A mercury-free LED backlight is also gentle to the
environment. |
