【Module Information】

Chip: drive IC

Size: LED module resolution

Scan Type: LED module scan type

Direction: LED module connection direction

Decode Type: LED module decoding type

Data Group: data group of one LED module

【Cabinet Information】

Regular: cabinet shape is rectangle

Irregular: Some modules are missing inside the cabinet, or the data groups have very complicated relation

Performance settings:

Symmetrical Output: if selected, the two 50pin output ports of one receiving card will work for the left and the right half of cabinet respectively.

D clock as the second road extended to 32 groups of data : if selected, the receiving card will provide 32 groups of data output to cabinet. But under this circumstances, LED display can achieve 1/8 scan maximum.

Group Swap: select this function when cabinet data group are not in regular order.

Refresh Rate: The higher the refresh rate is, the more stable the video is for watching.

Accelerate Rate: This parameter is used to increase the refresh rate. If N is selected, the refresh rate will be increased by N times, but will decrease LED display brightness.

Gray Scale: the more levels the gray scale is divided into, the more exquisite the shown images will be.

Gray Mode: There are three options for Gray Mode, Brightness First, Refresh Rate First and Gray First.

High refresh rate and high gray scale config procedure for scan LED display:

1. Select 【Gray First】 in Gray Mode, choose “16” times accelerate rate.

2. Select “25Mhz” Data Clock, LED module support required.

3. High refresh rate will cause serious afterglow, to reduce afterglow (can’t be eliminated) please increase “Blanking Time”, set Blanking Time between 30~100, for most LED displays (without afterglow reducing circuit), set “Line Change time” as a low value, for example “3”.

4. OE pulse width will become smaller when high refresh rate and high gray scale are selected, if LED module drive IC can not respond to the OE pulse width changing, the LED display performance at low gray scale levels will be reduced. So user should make a choice in this circumstance, higher refresh rate and gray scale levels or better performance at low gray scale levels.

5. 【Gray First】 mode is about 8% brightness efficiency lower than “Brightness First” mode, if brightness efficiency is more important to user, please select 【Brightness First】 mode, but please be noted in this mode “16” times accelerate rate is not supported, and the LED display pictures taken by a camera will not be as good as 【Gray First】 mode.

After config receiving card performance settings, like the pixels it manages, appropriate Data Clock, Refresh Rate, Gray Scale, Clock Phase etc., click 【Send to HW】 and 【Save File】.
