Real Black Drive System: Conventional plasma displays tend to
illuminate blacks, which lowers the contrast. In Panasonic plasma displays,
however, the pre-discharge emission intensity is greatly reduced, and the number
of emissions per field is cut from the usual 12 to 1. This dramatically reduces
black levels and provides deep, rich blacks. It also achieves a high contrast
ratio of 4000:1.
1536 Shades of Gradation: Plasma displays can suffer from an artifact
called "false contouring", where transitions between different shades of the
same color are too sharp. These transitions can appear as distinct lines between
the different shades of color. Having 1536 shades of gradation helps minimize
the false contouring artifact so color transitions take on a smooth, natural
Mach Band Effect Enhancer: The appearance of an object, as perceived
by the human eye, is influenced by the colors of the objects surrounding it.
This is known as the Mach Band Effect. Panasonic Plasma TVs feature an M.B.E
enhancer, which utilizes the principals of this theory to enhance the brightness
of objects on the screen, helping improve sharpness.
Gamma Enhancement System: The Gamma Enhancement System adds
subtle nuance to dark scenes and gives images greater depth by increasing the
number of gradation shades at low brightness levels. It employs non-linear
signal processing to reproduce images that help accommodate the high sensitivity
of the human eye. Additionally, the system features the Panasonic Plasma AI
function, which analyzes scenes and automatically adjusts peak brightness
according to the brightness of the images.
CableCARD Slot: This TV has a back panel CableCARD slot that allows
digital cable reception without a set-top box. CableCARDs will be available from
your local cable provider.
HDTV (ATSC) Tuner: The TV has a built-in over-the-air HDTV (ATSC)
tuner, so you don't have to purchase a separate digital set-top box to receive
and decode over-the-air HDTV/SDTV signals.
Native Resolution: The TH-37PD25 has a display resolution of 852 x
480. The HDMI input and component video inputs will accept 1080i, 480p, and
480i, and will display them as 852 x 480. All other input signals will also be
displayed as 852 x 480.
Progressive Scan Doubler: The progressive scan doubler displays a full
frame of video in 1/60th of a second by de-interlacing the incoming video signal
and progressively scanning the image. This scan doubler also provides even more
image enhancement by improving the quality of diagonal lines in a moving
Motion-Adaptive 3D-Y/C Digital Comb Filter:
This filter is designed to
eliminate hanging dots and work on diagonal patterns to eliminate the color
rainbow effect in closely spaced patterns by compensating for the motion that
occurs between fields. As a result, bright colors and fast action scenes are
displayed with incredible clarity.
Color Matrix: When viewing digital television programming from a DTV
receiver/decoder connected to the component video inputs, this TV will
automatically adjust the color parameters for 480p transmissions. Manual
adjustments are also possible for non-standard DTV formats.
2-Tuner Picture-in-Picture: This feature allows you to watch
two programs at once using the television's internal tuners. You can select PIP
or Split operation. During Split operation, the main picture and split picture
are side-by-side. During PIP operation, a small PIP frame is superimposed on the
main picture. The PIP frame can be moved to any corner on the screen and the
frame's size can be adjusted. If you want to use an external source for
picture-in-picture, you can choose from any of the TV inputs.
Freeze: This feature is used to freeze the main picture and display it
in a PIP or Split frame.
Depending on the input signal, you can choose one of the following aspect modes:
displays a 4:3 picture at its standard size
magnifies the central section of the picture
displays the picture at its maximum size but with slight elongation
displays a 4:3 picture at its maximum size but with aspect correction
applied to the center of the screen so that elongation is only apparent at
the left and right edges of the screen
Picture Mode: You can choose one of the following picture modes:
- Standard: recommended for normal viewing conditions with subdued
- Dynamic: provides enhanced brightness for viewing in a well-lit
- Cinema: for watching movies in a dark room; this mode provides a
soft, film-like picture
- Auto: automatically selects the mode that best suits the
brightness of the environment
BBE High-Definition Sound: BBE High-Definition Sound provides true
linear phase correction and dynamic amplitude compensation. With BBE, speech
intelligibility is improved and the dynamic range of musical passages is
restored to provide outstandingly natural sound.
BBE/VIVA 3D High Definition Sound System: BBE/VIVA provides a
musically accurate natural 3D image with hi-fi sound. The clarity of the sound
is improved by BBE while the width, depth and height of the sound image are
expanded by BBE's proprietary 3D sound processing.
Surround Function: The surround function lets you enjoy a concert hall
Sleep Timer: This television features a built-in electronic sleep
timer, set by remote control, that turns the TV off automatically after 30, 60,
or 90 minutes.
Programmable On/Off Timer: The programmable timer allows you to
program the TV set to turn itself on and off at designated times every day,
while being tuned in to a selected channel.
SD Card Slot: The SD card slot allows you to use the following media:
SD card, MultiMediCard, and miniSD card.
Note: A miniSD adapter is required to use a miniSD card.
Photo Viewer: The Photo Viewer lets you display JPEG images recorded
on media inserted into the SD card slot. When the media is inserted into the
slot, a thumbnail screen appears showing all the available images. The following
functions are available during playback: slideshow, zoom (2x, 4x), and image
rotation, which allows you to rotate the current image 90-degrees clockwise or
counterclockwise. During slideshow playback, you can choose one of the following
interval settings: 5 seconds, 10 seconds, 15 seconds, 30 seconds, 60 seconds, 90
seconds, or 10 minutes. The sequence of the slideshow can be set to Order (plays
the images in order) or Random (plays the images randomly). You can play a
slideshow once or repeatedly.
Note: Photo Viewer can only show DCF and EXIF standard JPEG
files with the following resolution: 64 x 64 to 8192 x 8192. The Photo
Viewer can display a maximum of 100 folders and 3000 files.
