SMD Screen displays are among the most recent developments in the field of fine pitch led package technology. In the realm of LED displays, the progressive formation of two distinct technologies for the manufacture of LED display panels has been brought about by the development of upstream packaging technology. These technologies are known as SMD and COB. These two technologies will allow us to manufacture micro LED display screens with extremely tight spacing. In addition, we will discuss some information with you on these two different technologies, SMD Screen.
The following is the specialized definition of IMD:
This scheme is also referred to as “N in 1.” A standard IMD model takes the shape of a 2*2 or 4-in-1 configuration when it is created. Each 4-in-1 package has four Surface Mount Devices (SMDs), and each SMD contains three chips (Red, Green, and Blue). IMD is a product that is between SMD and COB and possesses the benefits that are associated with each of these technologies. When it comes to the manufacturing of LED displays with a fine pitch of 0.9 millimetres, the most popular 4-in-1 model on the market is the NationStar IMD09. In the year, it became officially available for mass production, SMD Screen.
Advantages:
IMD has stronger anti-collision performance and higher SMT efficiency than regular SMD does. This is due to IMD’s smaller pitch. IMD combines the benefits of traditional SMD and COB and has correctly handled concerns relating to damage protection, black consistency, seamless splicing, light leakage, and maintenance. IMD also combines the advantages of classic SMD and COB. It has a greater contrast ratio, higher integration, is easier to maintain, and has a lower cost, all of which contribute to the fact that it is an excellent product for the development to finer pitches. Conventional SMT 1010 machines can still be utilised for the creation of IMD using a manufacturing procedure that is analogous to the original. LED display producers can speed up their transition to IMD display production by maintaining the SMT process. This is possible because there is already a mature supply chain for SMT.
Disadvantages：
IMD is running into the same issue as SMD, which is that there will always be a physical limit, leaving little possibility for IMD product growth. This difficulty is caused by the ongoing narrowing of pixel pitch.
As a result of the presence of numerous RGB chips in each package, the process of selecting bins for IMD products becomes more challenging if chip suppliers do not subdivide their bins further. It’s possible that the level of uniformity and consistency of the RGB chips contained in each package won’t be as great as that of LED displays composed of individual SMDs. Read more: Mustangled
