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.

Features

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.
