DIP LED Technology

Even though it is considered the oldest form of LED technology, it is far from obsolete. DIP LEDs are still widely used today for many signages and digital displays because of their durability and high performance.

It is easy to recognize a DIP LED because of its distinct structure. It has a cylindrical body and a spherical top and has the same shape as the bullet.

Each DIP LED has a single chip and semiconductor die that emits light when supplied with electricity. The LED chip is encased with a hard-plastic epoxy lens or case and two (2) connecting pins for easy soldering to any LED circuit or LED board.

Each DIP LED is only capable of producing one color. That is why it is commonly combined with the other two differently colored DIP LEDs to achieve the RGB (red, green, blue) color scheme.

This type of LED produces around 4 lumens per single LED, and the input power is 5 volts to 12 volts.

SMD (Surface-Mounted Device)

The advancement in LED technology has eliminated most of the limitations of using the earlier versions of LED screens. Before, LED displays were only based on DIP technology or Dual In-line package LED screens.

Now, there are several LED display screen technologies that you can choose from depending on which you find more suitable or fitting for your personal or business needs.

Some LED technology options available in the market are DIP, SMD, COB, and GOB. You can read our detailed article about the difference between these four here SMD Vs DIP Vs COB Vs GOB LED Screeen.

For this article, we will focus on Surface Mounted Diode (SMD) LED Display screens. This article will explain why it is a trendy choice and why you should have it too.


1. What Is An SMD Screen LED?

Unlike traditional LED technology that uses three different LEDs (red, green, and blue), SMD technology groups the LEDs together in one square or dot that can either be white or black.

Each grouping has a minimal diameter. The SMD LEDs are almost not visible separately, meaning the gap between each pixel or dot is unlikely to be noticed. This structure allows for smaller pixel pitches, which is ideal if you prefer ultra-high resolution. LED screens with 1 mm pixels are possible with this technology.

Since SMD LEDs can have three (3) diodes in a single chip, it’s highly versatile in producing adjustable color output levels. Think of it like this, instead of having separate diodes to create different colors, SMD technology makes it possible for each diode to produce any color. With this, users like you are guaranteed to have picture quality that has excellent sharpness and vividness.


2. How Do SMD LED Displays Work?


The SMD LED has 3-in-1 encapsulation. In other words, it integrates three cells into one system. Each system has a luminescent element or light semiconductor that emits light whenever electric current flows through it.

The SMD LED each has a cathode contact and an anode contact for each semiconductor luminescent element.

These LED squares are soldered on the panel circuit board through a process called polarization using high-tech equipment. It is a crucial step for SMD technology to prevent loose attachment or non-functioning LEDs.

Protective resins are then used to cover the upper/outer part of the chip to protect it from scratch or intrusion, which can damage or affect its light quality. The resins are available in different shades and colors.


3. What Do The Numbers In The SMD Mean?


Each SMD LED type has four-digit. These numbers that you see after “SMD” refer to the size of the LED used in the LED display. The first two digits refer to the length, and the next two refer to the height (tenths of mm).

Here’s a table for your guidance and reference:
