Product Feature:Led display receiving card A8 Model
|
Features
|
Description
|
|
Supporting HDR10
|
A8 can work with the independent
controller MCTRL4K featuring large loading capacity to support HDR10
compliant video input, realizing larger dynamic brightness range and larger
color space, making the image smoother.
|
|
Supporting low latency (Customized
function)
|
A8 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 1 frame.
|
|
Supporting 18Bit+ grayscale output
|
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.
|
|
Supporting 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.
|
|
Supporting arbitrary-angle
rotation for the screen
|
Make A8 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,
A8 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, A8 supports
quick adjustment of bright and dark lines, which can remove the seams between
modules and between cabinets.

Features
|
Description
|
|
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.
|
|
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, A8 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 auto module 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 on NovaLCT.
|
|
Supporting LCD module
|
Supports NovaStar's general 5-pin
LCD module.

Features
|
Description
|
|
|
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 A8 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.
