First, what are the parameters of LED display
Due to different manufacturers, the number of parameter items of its LED display is also different, but basically each display has more than two dozen, after analysis and classification, can be divided into three types: core parameters, basic parameters and auxiliary parameters.
1. Core parameters
The core parameters are the parameters necessary for the LED display, if the setting is incorrect, the light will not be displayed, and the heavy will burn the screen. The core parameters include cascade direction, OE polarity, data polarity, LED display type, color, scanning mode, walking point order and line order, a total of 8 items.
2. Basic parameters
The basic parameters are the basic parameters of the LED display, if the settings are incorrect, it cannot communicate, does not display, or the display is not normal. The basic parameters include display width, display height, control card address, baud rate, IP address, port number, MAC address, subnet mask, gateway, LED display refresh rate, shift clock frequency and line blanking time, a total of 12 items.
3. Auxiliary parameters
Auxiliary parameters are parameters set for better display and control, including control card name, communication display mark, brightness, and screen opening and closing time, a total of 4 items.
Second, how to set the parameters of the LED advertising screen
Although the ed scope of application of LED display is becoming more and more advertised, most people still do not know much about some basic setting information of LED display. How to set the parameters of the LED display is the first to do.
For single and double color bar screens, this setting is relatively simple. It is often referred to as the control parameter setting. The user can change it at will. All types of controllers are similar, but some invisible parameters and some software require shortcut keys to call out, or require engineering passwords. Treat these Certain professional knowledge is required.
In short, different control cards have different setting methods. You can download the control card manual from the website, or make a after-sales call.
Third, how to set the parameters of outdoor LED display
A light bulb is a dot. Then you see what your cell board looks like. How long is it and how wide is it? Then you can use some basic math to figure it out.
Indoors are generally 64*32, and outdoors are generally 32*16.
Outdoor: 21*32=672 4*16=64
Indoor: 21*64=1344 4*32=128
