LEDs are a type of light bulb that have come into popularity due to their efficiency, environmentally friendly nature, and long lifespan. When used commercially in digital signs and scoreboards, LED diodes have the ability to improve the light quality, durability, and cost of the sign.

There are many different types of LEDs but most used for LED display is DIP and SMD for the last 20 years. Although they are slightly similar in mechanics (they’re both energy efficient light sources that are used in conjunction to make one big illumination), they are quite different in makeup, rendering them better suited for two different applications.

We'd like to explain the main differences between DIP & SMD LEDs and how they are best used. Do you understand the difference between SMD LED display and COB LED display?

DIP (Dual Inline Package)

DIP LEDs or dual in-line packages are constructed to resemble a traditional light bulb, with a single colour per component. A red, green, and blue bulb are joined together to create an endless possibility of colours. A fourth white one can also sometimes be added for additional variety and brightness. These bulbs have a low lumen output, at about 4 per LED.

The small triad of bulbs are pieced together to create the large intended display image. As such, bulbs can be seen within the screen and have a high pixel pitch. DIPs are usually made durably, making them resistant to weather and able to withstand hard conditions. Due to the limitations of their visibility, and weather-resistant design DIP bulbs are often used on outdoor signs.

SMD (Surface Mount Diode)

SMD LEDs or surface mount diodes are lightweight LEDs built inside of an enclosed case that is commonly used in a variety of screens and devices on the market. They are small in design offering a ton of versatility in their use and screen configuration and offering a low pixel pitch. These types of LEDs are a popular choice due to their energy efficiency, long lifespan.

As an improved design from traditional LEDs, SMDs offers a high lumen output of about 50 to 100 lumens per watt. They can be extremely bright with crisp output, clear images, and true to colour nature. Not only are SMDs a cost-effective choice, they offer superior quality for close viewing, high resolutions and bright images, making them great for indoor signs and screens. Do you know the difference between indoor LED display and outdoor LED display?

What’s the difference?

LED packaging technology:

SMD displays use surface mount LED packaging technology, and the LED chips are directly mounted on the surface of the LED module. This makes SMD LEDs thinner, lighter, and have a wider viewing angle.
The DIP display screen uses dual in-line packaging technology. The LED chip is inserted into the hole of the module through the pins and then welded. This makes DIP LEDs larger and thicker in packaging.

Brightness and visibility:

Since the LED chips of SMD displays are directly on the module surface and the LED light source is closer to the audience, SMD displays usually have higher brightness and wider viewing angles. This enables SMD displays to provide excellent visibility in both indoor and outdoor applications.
DIP displays are usually used in indoor applications due to their packaging characteristics, while outdoor applications may require more light sources to achieve sufficient brightness.

Resolution and image quality:

SMD displays typically have higher resolution and better image quality because the LED chips can be packed closer together, allowing for finer pixel pitches. This makes SMD screens suitable for applications requiring high resolution and image detail, such as indoor LED video walls.
DIP displays typically have larger pixel pitches and relatively lower resolutions, making them suitable for less demanding applications such as billboards.

Maintenance and serviceability:

SMD displays are generally easier to maintain because the LED modules are easier to replace and don't require much soldering work.
Maintenance of DIP displays can be more challenging because replacing LED modules involves complex soldering work.

Durability:

Because DIP displays have relatively larger LED packages, they may in some cases be more durable and able to handle harsh weather and physical damage.
SMD displays are more fragile and require additional protective measures to ensure long-term reliability.

Overall, SMDs are a newer, more improved LED design that makes them capable of offering high-quality resolution and crisp, bright signs. Being a newer technology SMDs are much smaller in size than DIP’s, with a superior colour output. They are a more common choice when it comes to digital screens not only due to their capabilities but also their efficiency and lifespan. Typically, SMD displays are more suitable for indoor and outdoor applications, while DIP displays may be more suitable for special environments and large billboards. Do you know the current price of outdoor LED displays?

DIPs are a reliable choice if outdoor signs are your goal, due to their weather-resistant nature. Compared to incandescent bulbs these LEDs are still energy efficient and of a preferred quality.

Regardless of which type ultimately make up your scoreboard or display or digital sign, LEDs are a great environmentally and cost-friendly option that your patrons will enjoy. 

While choosing an LED display, customers generally ask questions like “How do I decide which specifications are important?”, “What is the difference between RGB (DIP) and SMD technologies?” and many others.

Following are few important features will enable you to use these displays for advertising purposes both outdoor and indoor:

• High contrast and brightness
• Wide viewing angle
• Playing video and graphics, displaying animation
• Setting the number of times an ad is shown
• Managing and programming online
• Time of the day and distance do not affect the working capacity
• Time of year, weather conditions and ambient temperature do not affect the working capacity

One of the major advantages of an LED display is its reliability and long LED life (up to 10 years). Furthermore, even if a part of it is damaged, the display will not stop working. The faulty cluster will stay unnoticeable.

Now Come to Technologies used: DIP and SMD Technology

I'm sure many of you have already understood the difference by the above pictures only. Let me explain with more details

Direct In-line Package LED Technology

In a DIP display, the LED bulbs are separated from each other and are clearly visible. From every angle of the screen, the red LED, the green LED and the blue LED is visible. The DIP 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 weatherproof each module.

The LEDs used in this module are also in relief; this means that a non-homogenous contrast is sometimes exhibited as compared to some SMD modules which are flat and do not reflect any external light.

The DIP technology also proposes a “virtual pitch” technology. This consists of adding a fourth white LED to emphasize the definition and visibility of the screen. A DIP module digital screen will ideally produce about 4 lumens per LED. Because of these features, the DIP module does not allow visibility to go low and makes it a more globally robust option – hence being perfect for outdoor solutions. When compared to SMD modules, DIP is always the better option for outdoor use.

Surface Mounted Diode LED Technology

In an SMD module, the three colors of LED bulbs are encapsulated into one slim case which is directly soldered onto a circuit. The red, green and blue LEDs are visually regrouped into a single point, producing either the color black, or white. This point is either a circle or a square, which has a diameter of just a few millimeters. These modules can be made to as small as 1mm in size.

The LEDs are not directly visible in this module. The best screens in use today have reached a distance of about 0.0 millimeters between each point on the screen.

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 much higher resolution as compared to DIP modules and this is why SMD modules are more popularly used in indoor solutions. Although this module is beginning to develop a focus on high definition outdoor digital devices, the main focus remains on indoor LED signs.

Pros and Cons:

• The technological advancements have played a major role in reducing the price gap between SMD and DIP modules. still, DIP modules are still the cheaper and mostly used in outdoor LED signs.
• Due to the design of DIP modules, they are better at withstanding different weather conditions and hence are preferred for Outdoor LED Display solutions
• For indoor use, SMD modules are mostly considered because the smaller pixels provide better color and amazing quality of text and images. The colors produced are much crispier, closely resemble the intended color and have better color uniformity.
• The maintenance of SMD modules is higher and they have a shorter lifespan because of the heat dissipation issues in the way these modules are designed.
• 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.
• SMD modules are lightweight, have a much wider viewing angle and are more energy-efficient.
• As a result of its features and being much less pixelated, SMD modules have a more natural end result (look and feel of an image on a digital display).

In either of the technology, there is one thing is common – each pixel consists of three LEDs: Red, Green and Blue (RGB). There is no such result that which is better, its totally depend on the requirement,

I can conclude that SMD modules are more often used in indoor solutions. On the other hand, DIP modules are more robust and ideal for outdoor applications. Once the maximum viewing distance for looking at each of these screen types is reached, there is really no visible difference between the two technologies.
