some questions about LED display

  1. What is LED?
    • LED is the abbreviation LED (Light emitting diode), the display industry, said the “LED”, refers specifically to emit visible light LED;
  2. What is a pixel?
    • The minimum luminous LED pixel display, with ordinary computer monitor, said the “pixel” has the same meaning;
  3. What is the pixel pitch (dot pitch)?
    • From the center of one pixel to another pixel distance from the center;
  4. What is the LED display module?
    • Composed by a number of display pixels, the structure of independent LED display can be composed of the smallest unit. Typical are “8 × 8″, “5 × 7″, “5 × 8″, etc. Through specific circuits and structures can be assembled into a module;
  5. What is DIP?
    • DIP is a Double In-line Package acronym, dual in-line assembly;
  6. What is SMT? What is SMD?
    • SMT is Surface Mount Technology (Surface Mounted Technology abbreviation), is the electronics assembly industry of the most popular technologies and processes; SMD is a surface mount device (Surface mounted device abbreviation);
  7. What is the LED display module?
    • Determined by the structure of the circuit and installation, with display, the display functions through a simple assembly to achieve the basic unit;
  8. What is the LED display?
    • Some control by way of LED device array formed by the display screen;
  9. What is the plug lamp module? What are the advantages and disadvantages?
    • DIP package is the lamp will light foot through the PCB, soldering tin filled through the hole in the lamp, made by this process module is inserted lamp module; advantages of a large angle, high brightness, good heat dissipation ; disadvantage is that pixel density;
  10. What is the surface-mount module? What are the advantages and disadvantages?
    • SMD also known as SMT, the SMT package soldered welding process lights through the surface of PCB board, not through the PCB board light feet, made by this process is called surface mount module module; advantages are: great view, soft display image, pixel density, suitable for indoor viewing; drawback is the brightness is not high enough, heat lamp itself is not good enough.
