High-Quality Images, Advanced Functions,
Low Power Consumption
and Excellent Cost-Performance.
A 47 cm (18.5 inches) LCD Monitor for Diverse Broadcasting Needs.
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.
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.
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.
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 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.
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.
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.
• RS-485 (RJ-45), RS-232C (9-pin) and GPI (9-pin) remote input terminals.
• Tally lamp (red/green/amber).
• Key Lock function disables the front panel operation/control functions, except for Power switch, menu operation and sound level adjustment.
• Monaural speakers and headphone jack on the front panel.
• Fanless drive and its quiet operation make this model ideal for use in editing studios or MA rooms.
• Auto power down with no operation nor signal input for a certain period of time.
• Tilt Stand is included as standard (detachable).
