Difference between DIP and SMD type LED modules

The choice made by investors regarding the module of LED sign they want to purchase will vary based on the purpose for which the sign will be used.

DIP (Direct In-line Package)

This module is put together by using three bubble shaped color LED bulbs that are joined with two connector feet. Sockets or through-hole soldering is used to mount these DIP modules. With sockets, replacing the device is very simple and also there is no risk of damage caused by overheating (which occurs during soldering).After the assembling of DIP outdoor modules is done, heat-dissipating silicone is used to weather proof each module.


SMD (Surface Mounted Diode)

smdIn an SMD module, the three colors of LED bulbs are encapsulated into one slim case which is directly soldered onto a circuit. Because these diodes are mounted onto only one surface on the board, they are small and can be placed closer together. Closer placement results in a higher resolution and this is why SMD modules are more popularly used in indoor solutions. These modules can be made to as small as 1mm in size.

Pros and Cons:

  • The technological advancements have played a major role in reducing the price gap between SMD and DIP modules. Yet, DIP modules are still the cheaper ones and are mostly used in outdoor LED signs.
  • Due to the construction of DIP modules, they are better at withstanding various weather conditions and hence are preferred for outdoor LED solutions.
  • For indoor use, SMD modules are better because the smaller pixels provide better color and amazing quality of text and images.
  • The maintenance required with SMD modules is higher and they have a shorter lifespan because of the heat dissipation issues in the way these modules are constructed.
  • The pixels in SMD modules are dimmer and consume more power; roughly about 6500 NITs. Compared to this figure, DIP modules average at about 12000 NITs.
  • The SMD chips are coated in white at the back and this affects the outcome of the color on the screen. For example, darker colors may have more of a grayish effect on SMD module screens.
