Repeat the step till you get an appropriate
result.
You can modify multiple border values and the
“Send” button reflects all the result at a time.
If a visible boundary still remains even after the
compensation, follow the boundary adjustment
(p. 43).
Color calibration memory saving
Once completed all the necessary compensation,
save all the compensated values in the control unit.
Select the control units that include the adjusted
LED units and click the “Save in Control Unit” button
in the “Maintenance” tab to save. It takes about 3 to
5 minutes to complete the saving.
The color data in the “LED unit adjustment” menu
is independent from the system memory. Surely
save it after the adjustment.
System memory
Sensor
Once the color calibration memory setting is
completed, set the “Sensor feedback” menu
accordingly.
To display a static image for a long period of time,
set it “Run”, which corrects image persistence. To
display moving pictures or images that frequently
change, leave it “Off” as the correction effect would
be less.
The sensor function periodically monitors the
brightness and its lighting time of every single
LED chip. Using this data, it automatically controls
the luminance to correct the brightness
discrepancy of the LED chips.
After a long term operation, when the brightness
reaches a low limit specified in the “Threshold for
feedback” menu, the LED chip will be separated
from the brightness control group. It is to avoid
the situation that a partial dark area makes the
entire LED wall too dark.
This limit can be changed. Lower setting keeps
the brightness uniformity for a longer period
while the entire LED wall will be darker. The initial
setting is 45 %.
System memory saving
After you change the Senor menu, surely click the
“Save” button to save the setting in the control unit.
