Led display receiving card A8s Model
Product Feature:Led display receiving card A8s Model
Features
Description
Supporting HDR10
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, making the image smoother.
Supporting low latency
(Calibration not supported after
rotation)
A8s can reduce the frame latency
(for the module that the RAM is built within the driver IC) of the video source
on the receiving card end to one frame.
Support 18Bit+
Enabling of 18 bit mode could improve
LED display grayscale by 4 times, and therefore avoid grayscale loss caused by
brightness reduction and make images finer.
Support 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.
Support 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.
Supporting pixel level brightness
and chroma calibration
Working with NovaLCT and NovaCLB,
A8s supports brightness and chroma calibration on each pixel.
Supporting 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°(90°, 180°, 270° and 360°).
Supporting 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.
Supporting 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.
3.2 Improvement in Maintainability
Features
Description
Supporting the smart module
(Supported by dedicated firmware
program)
The smart module is composed of
Flash and MCU.
Flash could store calibration
coefficients and module information. MCU could 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 could make
monitoring unit smaller, requiring no independent monitoring card and saving
cabinet space.
Supporting LVDS transmission
(Supported by dedicated firmware
program)
The transmission mode of
low-voltage differential signaling (LVDS) 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, and better stabilizes the image output.
Supporting module auto calibration
After the module has been
replaced, the receiving card can automatically read the new module ID and
calibration coefficient which could be saved to calibration system files.
Supporting Mapping function
Enable the Mapping function on
NovaLCT, then the target cabinet will display the cabinet number and Ethernet
port information, and the user could get the receiving card`s location and
wiring route.
Supporting setting of images
pre-stored of the receiving card
On NovaLCT, the specified images
could be set as the screen startup image and images used when the Ethernet
cable is disconnected or no video source signal is available.
Supporting module Flash management
On NovaLCT, lamp panel Flash could
be managed.
Supporting 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

Features
Description
on NovaLCT.
Supporting LCD module
Supports NovaStar's general 5-pin
LCD module. The LCD module is connected to the HUB board to display
temperature, voltage, single operating time and total operating time of the
receiving card.
Support one-click application of calibration
coefficient in module Flash
In the event of network outage,
hold down the self- test button to read the calibration coefficient in module
Flash back to the receiving card.
3.3 Improvement in Hardware
Reliability
Features
Description
Supporting dual-card backup
In the high-reliability
environment, single HUB board could be populated with two A8s 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.
Supporting dual-power backup
detection
Two power supplies could be
simultaneously connected, and operating status of the power supplies could be
detected.
Supporting 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.
3.4 Improvement in Software
Reliability
Features
Description
Supporting readback of firmware
version
On NovaLCT, the firmware versions
of the receiving card can be read back.
Supporting dual-backup and restoring
of the calibration coefficient
Calibration coefficients could be
saved to both the factory area and application area at the same time.
Calibration coefficients in the
factory area is default as the delivery value, while the calibration coefficient
in the application area could be modified or be restored to the factory reset
by the user on NovaLCT.
Supporting readback of
configuration file
l On NovaLCT, the receiving card
configuration parameters can be backed up to the receiving card.
