Priority Mode
◆
Brightness Priority: Protecting the brightness lost less, then do refresh acceleration, usually used
for outdoor display require high brightness.
◆
Refresh Priority: In this mode, it will sacrifice about20% brightness efficiency. It can update
Frequency clearly. Usually used for indoor display.
◆
Gray level Priority : If for lower brightness requirement, it can select this mode. Usually used for
indoor led display.
5)
Output mode
◆
Normal output: For ordinary HUB type.
◆
Two separate output: For sacrifice half control height to increase 1 times control width (Refresh
rate and brightness no change)
◆
Four separate output: For sacrifice 3/4 control height to increase 4 times control width
(Refresh
rate and brightness no change)
Note: Two separate output and Four separate output can not use together with Extension board
6) Gamma: The Gamma represent the contrast degree between light and dark. The higher data the
higher contrast. The range 1.0-6.0 and usually set 2.8
7) Display calibration: For color correction (Red,Green,Blue)
8) Use Expansion board: For sacrifice half control height to increase 1 times control width (Refresh
rate and brightness no change)
9) Use20 Groups of RGB: Just used for specified HUB, Like HUB75(20 Height)
10) 138 Decoder: According to led module, whether use 138 decoder.
11) Data Polarity: Two types of High effective and low effective .If in high effective, the LED
light will be lighten up, and shut down with low effective
12) OE Polarity: The OE Polarity with same features as Data Polarity.
13) Phase: The relative time relationship between moving clock and moving data.
If showing photo have flicker or dislocation, adjust this parameter it can eliminate
14) Duty cycle: The moving clock of duty cycle. If change this data, it can increase the
scanning moving clock, usually set 50%
15) Blank lines: When refresh rate high, it could result showing afterglow, adjust this data it
can decrease affect, but can not eliminate. It used for scan modules, for static module it is useless
16) Luminance efficiency: The higher and the more brighter, usually set 85%
