introduction to products

Novastar-DH7516S

The DH7516S is a cost-effective receiving card. For PWM driver IC, the maximum on-load resolution of single card is 512×384@60Hz; For general driver ics, the maximum on-load resolution of a single card is 384×384@60Hz. Support brightness correction, fast light and dark line adjustment, 3D, RGB independent Gamma adjustment, screen 90° multiple rotation and other functions, improve the screen display effect, improve user experience.

DH7516-S uses 16 standard HUB75E interfaces for communication, has high stability, and supports up to 32 sets of RGB parallel data, which is suitable for the construction of a variety of field environments.

product feature
Improve display	Brightness correction: the brightness of each light point is corrected to effectively eliminate the brightness difference, so that the brightness of the whole screen is consistent. Fast light and dark line adjustment: Adjust the light and dark lines caused by module splicing and box splicing to improve the visual obtrude caused by bright and dark lines 3D: Output 3D images with the controller that supports 3D functions RGB IndependentGamma adjustment: With the controller that supports RGB independent Gamma adjustment and NovaLCT (V5.2.0 and above), adjust "red Gamma", "green Gamma" and "blue Gamma" respectively. Effectively control the display low gray uneven, white balance drift and other issues, so that the picture is more real. The screen is rotated in a multiple of 90° (0°/90°/180°/270°)
Improve maintainability	Correction factor: The correction factor is quickly uploaded to the receiving card to improve efficiency. Mapping 1.1: Displays the controller number, receiver card number, and network port information on a container to clearly obtain the location and cabling mode of the receiver card. Temperature and voltage monitoring: real-time monitoring of the receiving card's own temperature and voltage without other peripherals. Box body fluid display: display the temperature, voltage, single run time and total run time of the receiving card through the box LCD module. Error code detection: Detects the communication quality of the receiving card network port and records the number of error packets to help eliminate network communication risks. Read back of the same program: read back the same program of the receiving card and save it to the local. Configuration parameter read back: Read back the configuration parameters of the receiving card and save them to the local PC.
Improve reliability	Loop backup: The receiver card is connected to the controller in a loop through the active and standby lines. When a fault occurs somewhere in the line, the screen body can still be displayed normally. Dual program backup: Two copies of the firmware program are saved at the factory of the receiving card to prevent the receiving card deadlock problem from abnormal updating process.
