LED display is a relatively common device in our life. It has the advantages of high brightness, low operating voltage, low power consumption, large size, and long life. It is widely used in airports, shopping malls, hotels, high-speed rail and other places. So do you know some knowledge about LED display? Next, follow the editor of YONGS LED display to learn together:
1. What is LED?
LED is the English abbreviation of Light Emitting Diode (LIGHT EMITTING DIODE).
2. What is a pixel?
The smaller light-emitting unit of the LED display has the same meaning as the pixel in the ordinary computer monitor.
3. What is the pixel distance (dot spacing)?
The center distance between two adjacent pixels. The smaller the distance, the shorter the visible distance. People in the industry usually abbreviated P to represent the point spacing.
4. What is pixel density?
Also known as dot density, it usually refers to the number of pixels per square meter of display.
5. What is LED display module?
It is composed of several display pixels, which is independent in structure and can form a small unit of LED display screen. Typical ones are 8*8, 8*7 and so on.
6. What is DIP?
DIP is the abbreviation of DOUBLE IN-LINE PACKAGE, double in-line assembly.
7. What is SMT? What is SMD?
SMT is surface assembly technology (abbreviation of SURFACE MOUNTED technology), which is a popular technology and process in the electronic assembly industry; SMD is the abbreviation of surface mounted device.
8. What is LED display module?
A basic unit with a display function determined by a circuit and an installation structure, which can realize the function of a display screen through simple assembly.
9. What is LED display?
Through a certain control method, the display screen is composed of an array of LED devices.
10. What is a plug-in module, and what are the advantages and disadvantages?
It means that the DIP packaged lamp passes the lamp pin through the PCB board, and fills the lamp hole with tin by welding. The module made by this process is the plug-in lamp module. The advantages are: high brightness, good heat dissipation, the disadvantage is The pixel density is low.
