A single A8s loads up to 512×384 pixels. Adopting the exclusive Image Booster Engine technology of NovaStar, the A8s can precisely calibrate the color gamut and grayscale of the screen, and improve the grayscale by 64 times. It also supports the pixel level brightness and chroma calibration, individual Gamma adjustment for RGB, low latency, 3D and HDR functions, greatly improving the brightness, grayscale and color performance from every aspect and offering users an ultimate visual experience with a uniform, smooth and lifelike image. The A8s uses high-density connectors for communication to limit the effects of dust and vibration, resulting in high stability. It supports up to 32 groups of parallel RGB data or 64 groups of serial data (expandable to 128 groups of serial data). Its reserved pins allow for custom functions of users. Thanks to its EMC Class B compliant hardware design, the A8s has improved electromagnetic compatibility and is suitable to various on-site setups that have high requirements. Features Improvements to Display Effect Image Booster Engine The Image Booster Engine has the following 3 functions which improve the display effect (the actual effect depends on the driver IC) from different dimensions. - Color Management: Switch the color gamut of the screen between multiple gamuts to enable more precise colors on the screen. - Precise Grayscale: Individually correct the 65,536 levels of grayscale (16bit) of the driver IC to fix the display problems at low grayscale conditions, such as brightness spikes, brightness dips, color cast and mottling. This function can also better assist other display technologies, such as 22bit+ and individual Gamma adjustment for RGB, allowing for a smoother and uniform image. - 22bit+: Improve the LED display grayscale by 64 times to avoid grayscale loss due to low brightness and allow for more details in dark areas and a smoother image. NovaLCT V5.3.1 or later is required. Pixel level brightness and chroma calibration Working with NovaLCT and NovaCLB, the receiving card supports brightness and chroma calibration on each LED, which can effectively remove color discrepancies and greatly improve LED display brightness and chroma consistency, allowing for better image quality. Quick adjustment of dark or bright lines The dark or bright lines caused by splicing of cabinets or modules can be adjusted to improve the visual experience. This function is easy to use and the adjustment takes effect immediately. Low latency 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 function Working with the independent controller which supports 3D function, the receiving card supports 3D image output. Individual Gamma adjustment for RGB Working with NovaLCT (V5.2.0 or later) and the independent controller which supports this function, the receiving card supports individual adjustment of red Gamma, green Gamma and blue Gamma, which can effectively control image non-uniformity under low grayscale and white balance offset, allowing for a more realistic image. Image rotation in 90° increments The display image can be set to rotate in multiples of 90° (0°/ 90°/180°/270°). Image rotation at any angle Working with the MCTRL R5 LED display controller and SmartLCT, the receiving card supports image rotation at any angle. HDR Supports HDR10 and HLG video sources. Working with the independent controller which supports the HDR function, the receiving card can reproduce the original brightness range and color space of the video source, allowing for a more lifelike image. www.novastar.tech 2 A8s Receiving Card Specifications Improvements to Maintainability Smart module (dedicated firmware required) Working with the smart module, the receiving card supports module ID management, storage of calibration coefficients and module parameters, monitoring of module temperature, voltage and flat cable communication status, LED error detection, and recording of the module run time. Automatic module calibration After a new module with flash memory is installed to replace the old one, the calibration coefficients stored in the flash memory can be automatically uploaded to the receiving card when it is powered on. Quick uploading of calibration coefficients The calibration coefficients can be quickly uploaded to the receiving card, improving efficiency greatly. Module Flash management For modules with flash memory, the information stored in the memory can be managed. The calibration coefficients and module ID can be stored and read back. One click to apply calibration coefficients stored in module Flash For modules with flash memory, if the Ethernet cable is disconnected, users can hold down the self-test button on the cabinet to upload the calibration coefficients in the flash memory of the module to the receiving card. Mapping function The cabinets 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. Temperature and voltage monitoring The temperature and voltage of the receiving card can be monitored without using peripherals. Cabinet LCD The LCD module connected to the cabinet can display the temperature, voltage, single run time and total run time of the receiving card. Bit error detection The Ethernet port communication quality of the receiving card can be monitored and the number of erroneous packets can be recorded to help troubleshoot network communication problems. NovaLCT V5.2.0 or later is required. Status detection of dual power supplies When two power supplies are connected, their working status can be detected by the receiving card. Firmware program readback The firmware program of the receiving card can be read back and saved to the local computer. NovaLCT V5.2.0 or later is required. Configuration parameter readback The configuration parameters of the receiving card can be read back and saved to the local computer. LVDS transmission (dedicated firmware required) Low-voltage differential signaling (LVDS) transmission is used to reduce the number of data cables from the hub board to module, increase the transmission distance, and improve the signal transmission quality and electromagnetic compatibility (EMC). Improvements to Reliability Dual card backup and status monitoring In an application with requirements for high reliability, two receiving cards can be mounted onto a single hub board for backup. In the case that the main receiving card fails, the backup card will serve to ensure uninterrupted operation of the display. The working status of the main and backup receiving cards can be monitored in NovaLCT V5.2.0 or later. Loop backup The receiving cards and the sending card form a loop via the main and backup line connections. If 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 backup of the application program Two copies of the application program are stored in the receiving card at the factory to avoid the problem that the receiving card may get stuck due to program update exception. Dual backup of calibration coefficients The calibration coefficients are stored in the application area and factory area of the receiving card at the same time. Users usually use the calibration coefficients in the application area. If necessary, users can restore the calibration coefficients in the factory area to the application area. www.novastar.tech 3 Appearance A8s Receiving Card Specifications All product pictures shown in this document are for illustration purpose only.
