Novastar MRV416-N LED Display Screen Receiving Card

The MRV416-N is a general receiving card developed by NovaStar Tech Co., Ltd. (hereinafter referred to as NovaStar). For PWM driver ICs, a single MRV416-N supports 8-bit video sources and resolutions up to 512×512@60Hz. For common driver ICs, a single MRV416-N supports 8-bit video sources and resolutions up to 512×[email protected] various functions such as Color Management, 18bit+, Pixel Level Brightness and Chroma Calibration, Quick Adjustment of Dark or Bright Lines, Multi-batch Adjustment, Low Latency, 3D, Individual Gamma Adjustment for RGB, and 90° Image Rotation, the MRV416-N can significantly improve the display effect and user experience.The MRV416-N uses 16 standard HUB75E connectors for communication. It supports up to 32 groups of parallel RGB data and is suitable for various on-site setups.

Features

1.Improvements to Display Effect
 Color Management
Support standard (Rec.709 / DCI-P3 / Rec.2020) and custom color gamuts, enabling more precise colors on the screen.
 18bit+
Improve the LED display grayscale by 4 times to avoid grayscale loss due to low brightness and allow for a smoother image.
 Pixel Level Brightness and Chroma Calibration
Work with NovaStar’s high-precision calibration system to calibrate the brightness and chroma of each pixel, effectively eliminating differences and enabling high consistency for both brightness and chroma.
 Quick Adjustment of Dark or Bright Lines
The different brightness of seams caused by splicing of modules or cabinets can be corrected to improve the visual experience. The correction is easy and takes effect immediately.
 Multi-batch Adjustment
Adjust the brightness of cabinets or modules to minimize display discrepancies caused by variations in production batches.
 Low Latency
Low Latency can be enabled or disabled as required, default is disabled. When enabled, the latency of video source on the receiving card end can be reduced to 1 frame (only when using modules with driver IC with built-in RAM).
 3D
Work with the controller that supports 3D function to enable 3D output.
 Individual Gamma Adjustment for RGB
Working with NovaLCT and the controller that supports this function, the receiving card supports individual adjustment to red gamma, green gamma and blue gamma, which can effectively control image non-uniformity at low grayscale conditions and white balance offset, allowing for a more realistic image.
 90° Image Rotation
The display image can be rotated in multiples of 90°(0°/90°/180°/270°).

2.Improvements to Maintainability
 Mapping 1.1
The cabinets can display the controller number, receiving card number, and Ethernet port information, allowing users to easily obtain the locations and connection topology of receiving cards.
 Settings of a Stored Image in the Receiving Card
The image displayed during startup, or displayed when the Ethernet cable is disconnected or there is no video signal can be customized.
 Temperature and Voltage Monitoring
The receiving card temperature and voltage can be monitored without using external devices.
 Cabinet LCD
The LCD module of the cabinet can display the temperature, voltage, single run time and total run time of the receiving card.
 Bit Error Detection
Real-time monitoring of the communication of the Ethernet port on the receiving card which helps users troubleshoot network communication problems.
 Firmware Program Readback
The receiving card firmware program can be read back and saved to the local computer.
 Configuration Parameter Readback
The receiving card configuration parameters can be read back and saved to the local computer.

3.Improvements to Reliability
 Loop Backup
The receiving card and controller form a loop via the primary and backup line connections. When a fault occurs at a location of the lines, the screen can still display the image normally.
 Dual Backup of Configuration Parameters
The receiving card configuration parameters are stored in the application area and factory area of the receiving card at the same time. Users usually use the configuration parameters in the application area. If necessary, users can restore the configuration parameters in the factory area to the application area.
 Dual Program Backup
Two copies of firmware program are stored in the receiving card at the factory to avoid the problem that the receiving card may get stuck abnormally during program update.
