15. The System will auto calculate the performance configuration parameters after done box
design，you can also adjust some options to make display effect better.
Refresh rate： an important indicator of the Led screen.Increasing the refresh frequency
can improve the water ripple when using the camera to take pictures.
Display mode ： It can be divided into
priority： In this mode， the brightness efficiency will be reduced while the refresh rate of
the module can be greatly improved. Grayscale priority： This mode will have a better
grayscale effect at low brightness.
Refresh rate times： High brush algorithm for improving visual refresh rate，default 16.
Data clock frequency： it is related to the design of LED module circuit and the driving
chip used.If the well-designed high brush IC is used ，the module can be reached higher
clock while gray degree and refresh frequency can be supported higher with the same
load area.
Grayscale： Increasing the grayscale according to the requirements of the LED. The higher
the grayscale，the better the picture quality. Generally，it is 12 to 14bit，(12bit grayscale
is equal to 4096 gradation grayscale)
Data clock phase：timing starting point of the clock setting.It can be adjusted when the
screen body has flash point ， flower screen and other abnormal phenomena.Generally
12.5~17.86.
Duty cycle： refers to the duty cycle of the clock phase. Changing this data can make the
scanning clock phase higher generally set to 50%.
Line changing time/discharge time/sweeping position： mainly adjust the scan screen
