When you need to buy a full -color LED display, many users do not understand some professional terms of LED display. When consulting the manufacturer, there will be a lot of things that do not understand, so let's take a look at it today.
1. Full -color LED display pixels, pixel diameter, point interval pixels:
The minimum light -emitting unit of the LED display is the same as the pixel meaning in the ordinary computer display; each of the luminous units that can be controlled separately in the LED display is called pixels.
Pixel diameter: Pixel diameter ： refers to the diameter of each LED light pixel point, and the unit is millimeter.
Pixel spacing: The center distance between the two pixels of the LED display is called pixel spacing, also called point spacing. The more dense spacing the point is, the higher the pixel density in the unit area, the high resolution, and the high cost. The smaller the pixel diameter, the smaller the point distance.
2. What is a full -color LED display module
LED display module: consisting of several display pixels, the minimum unit of the structure, the minimum unit that can form the LED display, and the typical 8*8 -point module.
3. Full -color LED display unit board
The full -color LED display unit board is the main body composition unit of the display, which is composed of luminous materials and drive circuits. Indoor LED display is usually composed of unit boards.
Full -color LED display module: minimum display unit for outdoor display. From several luminous diode pipes in the order of arrangement, packaging in a fixed mold shell through welding, glue and other processes, and becoming a module.
Full -color LED display unit box: The main body of the LED display is composed of the unit board in a certain order. Outdoor full -color LED display is usually composed of unit boxes.
4. What is SMT? What is SMD?
SMT is the abbreviation of surface assembly technology.
SMD is a surface assembly device (abbreviation of Surface Mountain Device), which is used for indoor full -color LED display, which can achieve single -point maintenance and effectively overcome mosaic phenomena.
5. What is a full -color LED display lamp module, what are the advantages and disadvantages?
The lamp module refers to the DIP packaging lamp through the lights through the PCB board. The tin is filled in the light hole by welding. Okay, the disadvantage is that the pixel density is small.
