The MRV328 supports pixel level brightness and chroma calibration, which effectively removes color difference, greatly improves display consistency of LED images, and presents finer displays to users.
Software and hardware designs of the MRV328 have fully concerned users' deployment, operating and maintenance scenarios, enabling easier deployment, more stable operating and more efficient maintenance.
The MRV328 is a new receiving card developed by NovaStar. A single MRV328 loads up to 256x256 pixels.
The MRV328 supports pixel level brightness and chroma calibration, which effectively removes color difference, greatly improves display consistency of LED images, and presents finer displays to users.
Software and hardware designs of the MRV328 have fully concerned users' deployment, operating and maintenance scenarios, enabling easier deployment, more stable operating and more efficient maintenance.
Hardware design:
ntegrates 8 standard HUB75 connectors, which makes the HUB board unnecessary.
Adopts the Gigabit Ethernet port, which can connect to the PC.
Software design:
Supports pixel level brightness and chroma calibration.
Supports setting of images pre-stored in the receiving card.
Supports status detection of temperature, voltage, Ethernet cable communication and video source signals.
Supports the 5-pin LCD module.

Description
|
|
Supporting pixel level brightness
and chroma calibration
|
Brightness and chroma calibration
on NovaLCT for each pixel could
remove color difference effectively,
make the brightness and chroma
of the whole screen highly consistent,
and improve the display effect.
|
|
Supporting setting of images
pre-stored in the receiving card
|
On NovaLCT, the specified images
could be set as the screen startup
image and images used when the
Ethernet cable is disconnected or
no video source signal is available.
|
|
Supporting status detection
of temperature, voltage,
Ethernet cable communication
and video source signals
|
On NovaLCT, the status of receiving
card's temperature, voltage,
Ethernet cable communication and
video source signals can be detected.
|
|
Supporting LCD module
|
Supports NovaStar's general 5-pin
LCD module. The LCD module is
connected to the HUB board to
display temperature, voltage, single
operating time and total operating
time of the receiving card.
|
|
Supporting readback of configuration file
|
On NovaLCT (V5.0.0 or later), the
configuration information stored in
the receiving card can be read back.
|
|
Supporting readback of firmware version
|
On NovaLCT (V5.0.0 or later), the
firmware versions of the receiving
card can be read back.
|
The MRV328 is applied to the LED display synchronous system which is generally composed of the LED display, receiving card, LED display controller (optional) and controller peripherals. The receiving card is connected to the LED display over HUB connectors.
The synchronous system requires connecting a computer to display the computer’s images and texts on the LED display. The synchronous system's structure is shown in the following figure.
