DIP LED Module VS SMD VS COB? One Article Tells You.

Pros:

For more information, please visit Moonleds.

(1)High brightness: 

DIP LEDs have a large size so as to produce higher brightness. Generally, DIP LED module can reach a brightness level up to 7,500 nits and even more than 10,000 nits.

This is a huge advantage that outdoor LED screen can utilize as high brightness is an indispensable factor that determines the final effect.

(2)Less power consumption

DIP LED displays are usually consumed electricity compared with SMD LED display, normally only need the 1/3 of electricity cost of SMD LED screen. Lower power consumption can save you more cost, and also is environmental-friendly.

(3)Longer service life

It is more durable than SMD LEDs in the long term as this packaging technology enables better heat dissipation. And this can prolong the working life of DIP LED modules that can be up to 100,000 hours.

(4)Seldom cold soldering problem

Because the long feet will be inserted into the PCB board directly, so there is seldom a cold soldering problem while SMD LEDs may cause such problems as the packaging method asking the LED lamp bead to mount on the PCB board.

(5)Better waterproof protection

Due to the packaging method, DIP LED modules have higher waterproof protection ability than SMD LED modules. Generally, DIP LED modules can reach IP65 waterproof level.

The water or moisture-entering will affect the normal operation of displays, and also shorten the life span. Thus, for some outdoor LED display screen which needs high waterproof protection, DIP LED displays can be one of the wise choices.

Cons:

(1)Longer viewing distance

Limited by the size of LED lamp beads, the pixel pitch of DIP LED modules can be relatively large. Generally speaking, now DIP LEDs only supports LED screens with pixel pitch larger than 6mm, that is P6.

The longer viewing distance makes DIP LEDs are not so suitable for some indoor LED displays that need small pixel pith.

(2)Narrower viewing angle

The viewing angle is narrower than that of the SMD LED module, which is only between 70 degrees to 110 degrees.

What is DIP technology?

DIP meaning (Dual In-line Package)

Dual in-line package is an electronic component package with a rectangular housing and two parallel rows of electrical connecting pins. The package is through-hole mounted to a printed circuit board (PCB) or inserted in a socket. DIP screens have a separate LED (R, G, B) for each of the three main colors: Red, Green, and Blue.

Now being used in just about every lighting situation pertaining to technology, they are most recognized by the two pins that extend from the bottom of the LED.

What is SMD technology?

SMD meaning (Surface Mounted Devices)

Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD).

SMD&#;s came about due to devices becoming smaller and the need to be able to have this type of LED fit within the smaller technology. So with that said, the uses for SMDs have rapidly increased in the first decade of the 21st century.

DIP LED screen is one of the old designs of LED if compared with the new technology of SMD. But it is also one of the most durable and stable solution for outdoor led display. SMD led display is an new technology these years and it becomes more and more popular now due to its better picture quality and higher resolution.

Advantages of DIP and disadvantages of SMD

1. For DIP that each pixel is made of three independent color(RGB) LED bulbs. Each bulb have two long feet. The long feet are inserted into PCB pad, so after through-hole soldering that there will be seldom cold soldering problem. The SMD LED display has short feet and the led lamp was mounted on the PCB pad which is more easier to cause cold soldering problem than the DIP one.
2. The long feet enable the led bulbs do better performance on heating dissipation. Better heating dissipation means long life time for led displays. So DIP LEDs would be more durable than SMD one from long run.
3. The DIP LED lamp size is big, it allows the led screens present higher brightness. Usually normal brightness DIP led displays can reach 7,500nits while the high brightness one can reach more than 10,000nits. Normally for outdoor SMD led display that the brightness is around 6,000nits.
4. DIP led screens consume less power if compared with same specifications SMD. Usually the power consumption of DIP LED displays is 1/3 less than the SMD one.

Compared to DIP displays, SMD displays have the following advantages:

• SMD&#;s are light weight, they have a much wider visual angle, the color output is much crisper and truer to the intended color along with better color uniformity They are more energy efficient then the DIP.
• SMD chips that features better heat dispersion, high lumen output (high lumen flux ) and longer overall life (low optical decay) than its predecessor the DIP LED .
• SMD&#;s having a much more natural look and feel of an image on an LED Display &#; being much less pixilated.
• SMD&#;s is that they can be easily manufactured using efficient quantity mass production, which helps keep the costs down during production. This will obviously save on labor costs and LED Displays will be able to have a larger scale of production.

In general that they both have advantages and disadvantages. If your outdoor fixed installation project requires high brightness and more durable application then you may choose DIP LED displays.

If you require higher resolution and wider viewing angle then SMD LED would be a good option. For indoor application, the viewing distance is shorter and usually we seek for the best picture quality and no need very high brightness, so the SMD led screens would always be the best option.
