content.
Easy maintenance
The receiving card supports configuration parameter read-back function, single point

customer system upgrade and maintenance.
Recommend loading
The receiving card can achieve the best display effect and application experience under
the control area of 256*256.
The display effect of the receiving card is directly related to the length of the on-load
module. In order to ensure the smooth screen adjustment, we generally recommend the
following settings (refresh priority, gray level 4096).

should refer to the 1/16 values.
If possible better to use the folio mode to improve the effect.
USER MANUAL
Set parameters
Display mode
Now, we have two modes, refreshment priority and brightness priority. Refreshment
priority is for high refresh rate, and you will get good feedback by mobile phone or camera,
but the brightness is lower. If you use brightness priority, you will get higher brightness
but photo by mobile phone or camera may not so good. Usually,for indoor screen,
brightness is not so important,so you can choose refreshment priority;But for outdoor
screen,brightness is needed,in this situation,need to choose brightness priority.
Brightness mode
For brightness mode, there are 3 modes: lower, normal or high brightness. If the

www.onbonbx.com 第 9页
display mode is fixed, then, the higher the brightness is, the lower the refreshment will be.
Or, on the same refreshment, the control width will be smaller. So, when the brightness is
enough, you can choose lower brightness mode, as to obtain a better refresh rate and
shooting effect.
Gray grade
On the same refresh rate, if the control size is the same, then, the gray grade is higher,
the effect will be better. But if the gray grade is higher, the control size will be smaller. So,
we usually suggest to use 4096 gray scale, do not over than 16384.
Refresh rate
It is not correct that the refresh magnification is higher, the effect will be better. If the
refresh rate is enough, the refresh magnification is lower, the shoot effect will be better.
Replacement clock
Replacement clock is also an important parameters. The higher the replacement clock is,
the control size will be larger(on the same refresh rate). But some kinds of modules are not
so good with quality, cannot use higher replacement clock, usually, there will be some
special flashing on the screen.
Gray from the first grade
If users need better low gray effect, you can choose. But the effect will be not so good, it
will be weird by your eyes. So, usually, we do not suggest.

FAQ
Gigabit or Sending card
If need better shoot effect, choose sending card mode.
Is there any affect for shooting by environment?
Usually, the environment brightness is the biggest fact for shoot. Cause the time of the
camera shutter is according the the environment brightness.
In indoor, the brightness is lower, so, the shutter will be slower, usually, 1/60 - 1/200
seconds. In this situation, if the refresh rate is about 1000, the shoot effect will be better.
But if in outside, the brightness is higher, the shutter time will be faster, usually, faster than
1/800 seconds. In this situation, the refresh rate should be about 3000.
So, for same screen, the shoot effect in night is better then in day. And that is the reason
why outdoor screen needs a higher refresh rate.
