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

COB Technology

COB (chip on board) LED has 3 LED chips (each RGB color) directly soldered on an LED substrate.

Manufacturers embed multiple LEDs within the inner substrate to produce one LED module. This process has a flat LED module surface encapsulated by a resin or lens for protection.

With the COB package design, the LED chips look like one LED lighting panel rather than multiple LED lights.

The chip on board (COB) technology is a process or manufacturing procedure. It describes the package design and structure of this particular LED technology.

And since it does not follow the traditional package design, the COB LED chips can occupy less space but still achieve their highest potential.

The COB technology offers higher reliability compared to the previously discussed LED technologies. The process does not require any supports and brackets, which, as a result, reduces the failure sites.

The COB LED display is more resistant to humidity, dust, rust, and moisture than other LED technologies such as the DIP and SMD.

B. What Are The Unique Features Of COB LED Display?

Direct Attachment. FOR EXAMPLE, COB LED display technology supports direct attachment to a heat sink without attaching the LED chips first to the PCB circuit board. As a result, you can expect the COB LED display to have better heat dissipation.

Unlike traditional LED technology that uses three different LEDs (red, green, and blue), SMD technology groups the LEDs in one square or dot that can 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, they are highly versatile in producing adjustable color output levels. Think of it like this: SMD technology makes it possible for each diode to produce any color instead of having separate diodes to create different colors. With this, users like you are guaranteed to have excellent sharpness and vivid picture quality.

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 has a cathode and 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.

What Do The Numbers In The SMD Mean?

Each SMD LED type has four digits. 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:
