COB LED vs. SMD LED, What is the Difference?

Ultra-high definition (UHD) monitors, along with advancements in LED packaging technology and improved packaging efficiency, have gradually become the trend in LED display screen development. It’s widely known that the smaller the pixel pitch of an LED display screen, the higher the resolution and the better the picture quality. In recent years, COB (Chip on Board) and SMD (Surface Mount Device) technologies have been dominating the small-pitch display market, serving as key elements in achieving a smaller pitch for LED display screens.

While both COB LED and SMD LED technologies have their unique characteristics and advantages, we often hear claims that COB, with its various technological advantages, surpasses traditional SMD. In this article, we will explore COB LED vs SMD LED technologies to help you make a wise decision when choosing the LED display screen that best suits your specific needs.

What is SMD LED Technology?
SMD stands for Surface Mount Device, which is a type of LED packaging technology that directly mounts LED chips onto a printed circuit board (PCB) using surface mount technology. In other words, materials such as lamp cups, brackets, and crystal components are packaged into different specifications of light beads, which are then soldered onto the circuit board through high-speed SMT machines using high-temperature reflow soldering.

SMD LEDs are known for their energy efficiency, and ability to produce perfect color. They enable more compact and versatile designs, making them suitable for various applications with limited space, such as electronic devices, lighting fixtures, automotive lighting, displays, and signage.

What is COB LED Technology?

COB stands for Chip on Board, and it’s a new LED packaging technology that is ahead of SMD. COB LED technology involves mounting multiple LED chips directly onto a ceramic or metal substrate, and then encapsulating them to form a single unit module, which is then assembled into a complete LED screen. The LED chips are closely packed in an array, resulting in higher levels of light output and better heat management.

COB LED is known for its high light output, excellent heat management, and uniform light distribution. Its closely arranged LED chip array also allows for better color mixing. Therefore, COB LED technology is very suitable for indoor and outdoor lighting, commercial displays, and horticultural lighting where high levels of brightness and performance are crucial.

Differences Between COB LED and SMD LED

Light Quality

In a COB LED display, the closely arranged array of LED chips allows for better color mixing and uniform light distribution. SMD LED displays have individual light beads, resulting in a point light source effect. In contrast, COB LED displays have an overall encapsulation above the light-emitting chips, which transforms the light source into a surface light source after scattering and refraction through the encapsulation.

Point light sources can cause glare because the light produced by SMD LED technology is the result of many light sources coupling together. In contrast, surface light sources have a more uniform overall light, providing better visual perception and reducing eye strain, making them more suitable for prolonged close-range viewing.

Contrast

After overall encapsulation using new processes, COB LED displays can achieve a contrast ratio of over 20000:1, whereas SMD LED displays typically do not exceed 10000:1. As a result, when viewed from the front, COB LED screens offer a viewing experience closer to that of LCD screens, with vivid colors and better detail representation.

Brightness

The difference in brightness between COB LED technology and SMD LED technology is due to variations in lumens. For COB LED display screens, there are at least 80 lumens per watt, while for SMD LED displays, it ranges from 50 to 100 lumens per watt. Therefore, COB LED displays have higher brightness, resulting in better image quality.

Color and Color Temperature

In terms of color and color temperature, SMD LED technology surpasses COB LED technology. SMD LED technology uses the three primary colors to provide a wider color range and has stronger color temperature adjustability. On the other hand, COB LED displays cannot individually select and match the optical performance of each light bead-like SMD screen. Instead, they only allow for emitting a single color, which can lead to color inconsistency when viewed from wide angles. However, precisely because COB LED emits only one color, it can provide more stable lighting.

Reliability

Since the light-emitting chips of SMD LED displays are packaged before being mounted, they have weaker overall protection and are more susceptible to damage from collisions. Additionally, SMD screens have poor water, moisture, and dust resistance, and cannot be wiped clean. However, they are convenient for on-site repairs and beneficial for later maintenance.

COB LED display screens use high-standard coating technology, with a front protection level of up to IP65, protecting against collisions, scratches, as well as damage from water, moisture, and UV rays to the internal components.

Additionally, due to the fewer number of components and the elimination of traditional LED chip structure packaging, COB LED generates less heat from each LED chip. Excellent heat management enables COB LED displays to support all-weather operation, even in extreme temperatures ranging from 30 to 80 degrees Celsius.

However, due to the overall encapsulation of COB LED screens, on-site repairs are not possible, requiring professional equipment and factory servicing, which can be inconvenient.

Energy Efficiency

Compared to SMD LED display screens, COB screens have higher energy-saving benefits. This is because the light-emitting diodes (LEDs) inside SMD LED displays often use a positive mounting process, leading to wire obstruction above the light source. In contrast, COB LED displays mostly use an inverted mounting process, resulting in unobstructed light sources. Therefore, at the same level of brightness, COB LED screens have lower power consumption and are more cost-effective.

Additionally, the epoxy resin used to encapsulate SMD LED displays has lower transparency, while the overall encapsulation used in COB LED displays has higher transparency, further enhancing the cost-effectiveness of COB LED displays.

In summary, when comparing COB LED and SMD LED technologies, COB LED has unparalleled advantages in terms of light quality, contrast, brightness, reliability, and energy efficiency, while SMD LED technology excels in color and color temperature adjustability. By understanding the differences between these two technologies, you can make informed decisions and choose the LED packaging technology that best suits your specific needs.

LED display screens are widely used in commercial advertising, conference presentations, and stage performances due to their stunning visual effects. Although they boast high brightness, vivid colors, and excellent clarity, installing and configuring LED display screens is crucial as it affects the final display performance and screen operation.

In this article, we will provide you with detailed instructions on how to install an LED display screen in a simple manner and what to pay attention to during installation and use. Mastering the installation and maintenance of LED display screens will promote your advertising effectiveness and information dissemination.

Installation Process of LED Display Screens

There are two common ways to install LED display screens: LED cabinet installation and LED module installation. The former integrates LED modules, power supplies, and other components into a cabinet, and the operator only needs to install the LED cabinet on the steel structure. Therefore, the LED cabinet installation method not only protects the internal components, making the overall structure more reliable, but also simplifies the entire installation process of the LED display screen, making it more user-friendly for operators.

LED module installation directly fixes the module to the steel structure with magnets, but requires technicians to install power supplies, LED receiving cards, and sending cards. Unlike LED cabinet installation, this method makes the LED display screen thinner and more aesthetically pleasing. In addition, LED module installation does not have a screen body, making it more suitable for the installation of indoor LED display screens with smaller areas, thus reducing costs.

LED Cabinet Installation

Preliminary Survey:

The first step in the LED display screen installation guide is to survey the location where you plan to place the LED display screen. This helps in planning the steel structure, the size of the LED display screen, and the installation method. For LED wall installation, you need to check if the building’s load-bearing strength is sufficient. For outdoor LED display screen installation, you may need to consider whether to use pole-mounted, wall-mounted, hanging, or embedded installation methods.
Steel Structure and LED Screen Design:

After surveying the installation environment for the LED display screen, the steel structure and the size of the LED display screen need to be designed according to the site conditions. Technicians need to ensure that the steel structure and LED screen can fit in the chosen installation location.
Screen Power, Distribution Facilities, and Network Control Line Design:

In addition to designing the size of the steel structure and LED display screen, it is also necessary to plan the power usage of the screen, distribution cabinets, control network cables, and the quantity of fiber optics, and ultimately produce a complete design drawing.
Install Steel Brackets:

Based on the size of the LED display screen and the designed steel structure drawings, weld rectangular pipes into a frame. The quality and safety of the steel structure should be a top priority, and it should be ensured that the brackets are stable during construction. Additionally, the dimensions of the steel structure need to be very precise, with welding errors not exceeding 4mm to avoid rework later on. It is also important to leave a maintenance passage of 700mm to 1000mm for later maintenance.
Install LED Cabinets on the Steel Brackets:

Install the LED cabinet units one by one from bottom to top and from one side to the other using bolts and connecting plates, securing them onto the frame to form a large LED display screen.
Connect Signal Lines:

After the LED cabinet installation is complete, the signal lines of the LED display screen need to be connected to the controller so that video, images, text, and other signals can be sent to the LED display screen via the sending box or video processor. Ensure that the signal line connections are secure to avoid any transmission issues.
Connect Power:

Once the LED display screen is installed, it needs to be powered. Connect the power cord of the LED display screen to the power outlet, ensuring that the power cord connections are secure to avoid wire breakage or short circuits.

LED Module Installation

Steel Structure and LED Screen Design:

The first step in installing LED modules is to survey the installation environment and design the steel structure and the size of LED display screens accordingly.
Install Steel Structure: The LED modules need a steel structure to support them. The steel structure is usually made of 40x40mm or 40x20mm rectangular pipes. After welding the steel structure, use expansion bolts, chemical bolts, or angle steel hooks to secure the frame to the wall. Leave a space of about 10mm behind the bracket for ventilation since indoor LED display screens generally cannot install fans.
Install Power and Cables:

After installing the steel structure, install the DC5v cables and power directly on the pipes or walls. The cable installation needs to be completed before installing the power. The power can be directly fixed on the side of the square tube or wall using mounting brackets and self-tapping screws or fixed on the side of the square tube using cable ties. The position of the power needs to be calculated according to the power load, the number of LED modules loaded by a single power supply when arranged horizontally and vertically.
Install LED Receiving Card and Connection Line:

Connect the receiving card to the data line, then fix it to the frame with a fixing plate or screws. Before installing the receiving card on the steel structure, the cable needs to be connected to the J1, J2, J3… interface of the receiving card in the order of the program file. Then connect the LED receiving card in order with the network cable. The network port near the power supply is the input port. In addition, the output port of the first receiving card should be connected to the input port of the second receiving card.
Install LED Modules:

After assembling the LED modules and magnets, connect the receiving card’s ribbon cable and the DC5v ribbon cable of the power output terminal to power the LED modules. The LED modules should be installed from bottom to top and from the middle to the sides to make it easier to control the vertical and horizontal errors. This is especially important for small-pitch LED display screens because it requires higher precision. When installing LED modules, make sure there are no gaps between the modules and they are installed tightly to avoid affecting the screen’s flatness and image display effect. Also, use short flat cables to connect the LED modules.
LED Screen Configuration and Calibration:

After installing four LED modules and one receiving card, turn on the power and begin calibration before continuing installation to avoid having to disassemble LED modules if problems arise. There is usually a test button on the control card. After turning on the power, you can press the button to test. If installed correctly, the LED screen will sequentially display red, green, blue, line, field, and point information. Then check if the network cable is working properly through a controlled computer. You can also maximize the visual aesthetics of the LED display screen by adjusting the luminous range during calibration.

What to Consider When Installing an LED Display Screen?

When installing an LED display screen, in addition to safety, stability, reliable connections, and calibration, it is also important to consider waterproofing, dustproofing, lightning protection, heat dissipation, and the impact of strong light to ensure the normal and stable operation of the LED display screen.

Waterproof, Dustproof, and Moisture-proof Design for LED Display Screen

The entry of water and moisture can cause serious damage to the internal components of the LED display screen. Therefore, outdoor LED display screens need to have backplanes and sealing glue to prevent water leakage. Additionally, the seamless connection of the LED display screen with the steel structure and the connection between the screen cabinets should be ensured. Proper drainage and ventilation measures should be in place within the steel structure and screen cabinets to prevent rainwater from entering the screen cabinets during extreme weather conditions. RIGARD’s outdoor LED display screens undergo waterproof testing before leaving the factory to ensure a protection level of IP65 or higher to withstand extreme weather.
Installation of Lightning Rods on Buildings and LED Screens

Discrete Packaging resulted in noticeable gaps between LEDs, reducing resolution and seamless visual effects.

To overcome these limitations, Surface Mount Device (SMD) was introduced in LED screen packaging. Surface mount device (SMD) is LED chips encapsulated with materials such as cups, brackets, leads, and epoxy resin in different sizes, which are then directly soldered onto printed circuit boards (PCBs). This packaging technology improved image quality and reduced power consumption, becoming the mainstream LED packaging technology today. However, the SMD technology increased the risk of LED color shift, failure, and damage due to the LEDs being exposed to the external environment without protection.

With the popularity of small pitch LED screens and the increasing demand for high definition, an innovative packaging technology called Chip On Board (COB) emerged. COB LED packaging technology involves directly mounting multiple LED chips on a PCB to form an integrated unit. This LED technology effectively reduces the pixel pitch of LED display screens, improves heat dissipation, and enhances the visual experience. Although COB packaging technology effectively reduces potential risks associated with SMD LED screens, it is currently challenging to produce COB LED screens on a large scale due to high technology costs and difficulties in maintaining color uniformity and color deviation.

In this context, a new technology called Glue On Board (GOB) packaging emerged as an improvement of the SMD packaging process. GOB LED display technology utilizes a proprietary transparent epoxy resin adhesive, which is applied to the surface of a PCB module that is soldered with thousands of SMD lamps, forming a special shield. GOB LED packaging technology provides a solution for protecting LED chips and enables cost-effective mass production, successfully addressing issues such as uneven surface flatness, color deviation, and the inability to mix light in COB displays. However, GOB LED displays still have drawbacks such as poor flexibility, high maintenance costs, weak heat dissipation performance, and viewing angle limitations.

Another significant development in LED screen packaging technology is the use of Hotmelt On the Board (HOB) packaging technology. HOB LED display technology combines the advantages of SMD and COB LED technologies, making it stand out among other techniques.

These display screens not only have visual appeal but are also energy-efficient and durable. However, like all electronic devices, LED display screens require regular maintenance to ensure optimal performance and longevity.

Maintenance can be done from the front or back of the display screen, and each method has its unique advantages and challenges. In this article, we will delve into the differences between front and rear maintenance of LED displays, focusing on their methods, pros and cons, and appropriate application scenarios.

What is Front Maintenance of LED Displays?

Front maintenance of LED displays, also known as front repair or front service, refers to the process of maintaining, repairing, or replacing the components of an LED display screen from the front. Front maintenance LED displays usually use magnetic fixation to secure the LED display modules and cabinets. When maintenance is required, the damaged LED modules can be easily removed from the front of the display screen using suction cups and repaired directly.

The front service is typically used in situations where accessing the back of the LED display screen is restricted or not possible, such as when the screen is wall-mounted or in a tight space. Front service LED displays not only make the screen thinner and lighter, saving space but also make future maintenance much more convenient. As a result, they are becoming increasingly popular among users.

Front Maintenance Methods for LED Displays

Although front maintenance LED displays are generally used indoors, there are still three different front maintenance methods to address different scenarios.

Front maintenance with screws

This is a front maintenance method where each LED module is fixed to the cabinet using screws. When the LED display screen needs maintenance, technicians can easily remove the damaged LED modules from the front using a hex wrench for repair.

This front screw system for LED displays is very safe and reliable, and it is suitable for outdoor installations, although it requires slightly more effort during installation. The application of outdoor front service LED displays is becoming more widespread because this method does not require a maintenance channel, saving screen thickness and reducing maintenance costs.

Here, we will explore spherical LED display solutions related to construction and operation.

Structural Engineering

Building such a massive spherical LED display requires precise structural engineering. The steel structure must be able to support the weight of the spherical LED panels, withstand external forces like wind and earthquakes, and ensure the safety of the audience inside.

During the construction of the MSG Sphere, an 86-meter temporary support tower was built in the center of the venue to erect a 154-ton compression ring on top of 32 trusses. The team also transported the world’s fourth-largest crawler from Belgium to position some of the largest and heaviest components.

Design and manufacturing of LED panels

Creating LED panels that seamlessly cover the spherical surface is a complex task. LED sphere screens require flexible LED panels with sufficient flexibility to adapt to the curved shape without distorting the image while maintaining consistent brightness and color across the entire surface. The manufacturing process must also ensure the durability and lifespan of the flexible LED panels as they will be exposed to various environmental conditions.

Image calibration and mapping

Achieving a seamless visual experience on a spherical LED display requires precise image calibration and mapping. Each LED panel needs to be calibrated to display the correct color and brightness levels, ensuring a uniform appearance across the entire surface. Additionally, content creators must consider any deformations caused by the spherical surface and accurately map the visuals to adapt to the curved shape.

Content creation and adaptation

Creating content for a spherical LED display is a unique challenge. Traditional flat-screen content may need to be adjusted or redesigned to fit the curved surface and take advantage of the immersive environment. Content creators must also consider the viewing angles and perspectives of the audience to ensure visually engaging experiences from any position within the venue.

Processing power and data management

Spherical LED displays require powerful processing capabilities and data management due to their size and resolution requirements. The LED panels need to receive and process a large amount of data in real time to display high-resolution images and videos. This requires robust hardware and software solutions to efficiently process and distribute content to the LED panels.

Heat dissipation and cooling

LED panels generate heat during operation, and heat dissipation is a critical concern for spherical LED displays. The large surface area of the display and the proximity of the LED panels can result in a significant accumulation of heat. Effective cooling systems must be in place to prevent overheating, as it can affect the performance and lifespan of the LED sphere screens.

Power supply and energy efficiency

Operating a spherical LED display requires a substantial amount of power. Ensuring a reliable and efficient power supply is crucial to avoid any interruptions during events. Additionally, considering the environmental impact of energy consumption, designing energy-efficient LED display screens is essential to minimize carbon footprints.

Maintenance and repairs

Due to the size and complexity of a spherical LED display, its maintenance and repairs can be challenging. Opting for flexible LED modular during construction can improve maintenance efficiency and reduce costs. To keep the LED sphere screen in optimal condition, a strict schedule for regular maintenance must be implemented, and trained technicians should be available on-site.

Conclusion

MSG Sphere represents a new era of live entertainment, where technology and creativity come together to create unforgettable experiences. The world’s largest spherical LED display will take audiences into a new dimension, blurring the boundaries between reality and virtual reality.
