1. Determine if the Fixed LED Video Display processing is synchronized with the Fixed LED Video Display or the asynchronous Fixed LED Video Display:
The display of the synchronized Fixed LED Video Display depends on the display settings, and the asynchronous Fixed LED Video Display does not depend on the display settings:
2. Determine if the Fixed LED Video Display is a partial display problem or a problem with the entire solution display;
If the partial display is abnormal, the problem of the communication party can be eliminated. Generally, it is determined that the Fixed LED Video Display hardware is faulty.
3. There are several reasons why the whole screen may not be displayed properly:
For the synchronized Fixed LED Video Display, you should confirm whether the display settings are changed, the communication is normal, and the transmission is normal.
4. Then whether the reception is normal:
For asynchronous Fixed LED Video Display, you should first confirm the parameters of the display screen: hardware address, width, height, IP change, if these parameters are correct, then test whether the communication is normal, and finally determine whether the Fixed LED Video Display control is normal.
5.Fixed LED Video Display unit board interface:
The Fixed LED Video Display consists of a block of display unit boards that are transmitted via a flat cable. Interface description of the cell board: N = ground (GND) L = latch (LAT or ST) S = time 钊 ' (Clk) 0 = enable (OE) E = energy (/OE) R = red data G = green Data U = blue data ABCD = row signal H = decoded row signal F = dangling v = vcc) modification.
In order to save customers' investment, we can provide transformation, update and other services for our customers' Fixed LED Video Display. According to the situation of the customer's Fixed LED Video Display, it can be roughly divided into the following three types:
6. Same display unit board interface
Many Fixed LED Video Display manufacturers display unit board interfaces are not standard. If the customer's led display unit board interface is the same as the above interface, we can upgrade the system, such as text screen, low gray screen, high gray screen. This method is low in cost and quick in effect.
