Novastar DH7508 LED Screen Receiving Card 256X256 Pixels, Replace MRV328

Novastar DH7508 High-Cost Performance LED Receiving Card is a cost-effective receiver card from Novartis. It can carry a maximum of 256X256 pixels on a single card and supports point-by-point brightness chroma correction, fast bright and dark line adjustment, 3D and other functions to improve the screen display effect and user experience. DH7508 adopts 8 standard HUB 75E interfaces for communication, with high stability and supports up to 16 groups of RGB parallel data. The hardware design complies with EMC standard, which improves the electromagnetic compatibility of the product and is applicable to the construction of various field environments. Improvements to Display Effect Pixel level brightness and chroma calibration Work with NovaStar’s high-precision calibration system to calibrate the brightness and chroma of each pixel, effectively removing brightness differences and chroma differences, and enabling high brightness consistency and chroma consistency. Quick adjustment of dark or bright lines The dark or bright lines caused by splicing of modules or cabinets can be adjusted to improve the visual experience. The adjustment is easy and takes effect immediately. 3D function Working with the sending card that supports 3D function, the receiving card supports 3D output. Loading capacity: − 192×256 pixels (PWM IC) − 176×256 pixels (Common IC) Improvements to Maintainability: Quick uploading of calibration coefficients The calibration coefficients can be quickly uploaded to the receiving card, improving efficiency greatly. Mapping function The cabinets can display the receiving card number and Ethernet port information, allowing users to easily obtain the locations and connection topology of receiving cards. Setting of a pre-stored image in receiving card The image displayed on the screen during startup, or displayed when the Ethernet cable is disconnected or there is no video signal can be customized.
