Overview

A8s is a high-end receiving card developed by NovaStar, featuring small size and large loading capacity with a single card loading up to 512×256 pixels (PWM IC). It supports up to 32 parallel data groups and 128 serial data groups. A8s can work with the independent controller MCTRL R5, making display rotate at any angel. A8s can also work with the independent controller MCTRL4K featuring large loading capacity and support HDR10 compliant video input, realizing larger dynamic brightness range and larger color space, and making the image smoother. A8s supports pixel level brightness and chroma calibration by working with NovaLCT and NovaCLB to realize calibration on each pixel. It can effectively remove color difference and greatly improve LED display image consistency, presenting smoother images to users. In addition, it also supports image rotation in 90° increments, creating richer images and improving visual experiences. Software and hardware designs of the A8s concern the user deployment as well as operating and maintenance scenarios, enabling easier deployment, more stable operating and more efficient maintenance.

Supports individual Gamma adjustment for RGB : A8s can work with the independent controllers and NovaLCT (V5.2.0 or later) which support individual Gamma adjustment for RGB to effectively control problems such as image non-uniformity under low grayscale and white balance offset by adjusting red Gamma, green Gamma and blue Gamma respectively, making image more real.

Supports precise grayscale correction : A8s can work with the precise grayscale tool and NovaLCT to further correct the screen image after calibration, enabling precise grayscale control. It also can work with the display technologies such as 18Bit+, ClearView, individual Gamma adjustment for RGB to improve display effect of screen and make image more real.

Supports HDR : The HDR function supports two video source standards: HDR10 and HLG. Working with the large loading capacity MCTRL 4K independent controller, A8s can accept HDR10 or HLG-compliant video input, supporting a higher dynamic brightness range and larger color space, allowing for a smoother image.

Supports low latency : A8s can reduce the frame latency of the video source on the receiving card end to one frame (only when using modules with driver IC with builtin RAM).

Supports 18Bit+ : Activation of 18Bit+ mode can improve LED display grayscale by 4 times, avoiding grayscale loss due to low brightness and allowing for a finer image.

Supports ClearView : Enable ClearView on NovaLCT to adjust the texture, size and contrast in different area based on human visual system to make image more realistic. 

Supports arbitrary-angle rotation for the screen : Make A8s work together with MCTRL R5 and then set the screen on SmartLCT to make display rotate at any angel, show different shapes, and present changeable images.

Supports pixel level brightness and chroma calibration : Working with NovaLCT and NovaCLB, A8s supports brightness and chroma calibration on each pixel.

Supports image rotation in 90° increments (Calibration not supported after rotation) : On NovaLCT, the image on the screen can be set to rotate in the multiples of 90° (0°, 90°, 180°, and 270°).

Supports quick seam correction : Working with NovaLCT, A8s supports quick adjustment of bright and dark lines, which can remove the seams between modules and between cabinets.

Supports 3D function : On NovaLCT or operation panel of controllers which support 3D function, you can enable 3D function and set the 3D parameters to make the LED screen display 3D effects.

Supports the smart module (Supported by dedicated firmware program) : The smart module is composed of Flash and MCU. Flash can store calibration coefficients and module information. MCU can communicate with the receiving card to realize monitoring over temperature, voltage and wiring communication status for the module. Working with the driver chip, A8s supports open circuit detection on LED. The smart module can make monitoring unit smaller, requiring no independent monitoring card and saving cabinet space.

Supports LVDS transmission (Supported by dedicated firmware program) : Low-voltage differential signaling (LVDS) transmission is used, which reduces the number of data cables that connect the receiving card's HUB board to the module, increases the transmission distance, improves the signal transmission quality, enhances the electromagnetic compatibility (EMC), and better stabilizes the image output.

Supports auto module calibration : After the target module (with module flash) is replaced, the receiving card, when powered on, can automatically read the new module ID and calibration coefficients which will be saved to the receiving card. 

Supports Mapping function : Enable the Mapping function on NovaLCT, then the target cabinet will display the cabinet number and Ethernet port information, and the user can easily get the receiving card’s location and data flow.

Supports setting of images pre-stored of the receiving card : On NovaLCT, the specified images can be set as the screen startup image and images used when the Ethernet cable is disconnected or no video source signal is available.

Supports module Flash management : On NovaLCT, lamp panel Flash can be managed.

Supports monitoring voltage and temperature of itself : The voltage and temperature of the receiving card itself can be monitored without using other peripherals. The monitoring data can be checked on NovaLCT.

Supports LCD module
 Supports NovaStar's general 5-pin LCD module. The LCD module is connected to the HUB board to display temperature, voltage, single run time and total run time of the receiving card.

 Supports cabinet LCD backlight control by working with NovaLCT (V5.2.0 or later).

 Supports cabinet run time reset by working with NovaLCT (V5.2.0 or later).

Support one-click application of calibration coefficient in module Flash : In the event of network outage, hold down the selftest button to read the calibration coefficient in module Flash back to the receiving card.

การปรับปรุงของฮาร์ดแวร์

Supports dual-card backup and status monitoring

 In the high-reliability environment, single HUB board can be populated with two A7s receiving cards. In case that the main receiving card fails, the standby one will serve in a timely manner to ensure normal operation of the display.

 During dual-card backup, A7s can work with NovaLCT (V5.2.0 or later) to monitor the working statuses of the main card and backup card. 

Supports dual-power backup detection : Two power supplies can be simultaneously connected, and operating status of the power supplies can be detected. 

Supports loop backup : HUB’s Ethernet port improves the reliability for the serial connection of the receiving card through main and standby redundant mechanism. Among the main and standby serial connection lines, if one fails, the other will begin to work to ensure the normal operation of the display.

การปรับปรุงซอฟต์แวร์

Supports bit error detection : A7s can work with NovaLCT (V5.2.0 or later) to detect the packet loss of the transmission link during communication between receiving cards. 

Supports readback of firmware : On NovaLCT, the firmware of the receiving card can be read back and saved in the local PC.

Supports dual-backup and restoring of the calibration coefficient : Calibration coefficients can be saved in both the factory area and application area at the same time.

 Calibration coefficients in the factory area are the factory defaults.

 Users can save the calibration coefficients configured by themselves in the user area and can also restore the calibration coefficients in the user area to factory defaults.

Supports backup and readback of receiving card configuration file

 On NovaLCT, the receiving card configuration parameters can be backed up in the receiving card.

 On NovaLCT, the receiving card configuration parameters can be read back.
