What Is MicroLED?

MicroLED displays are the next generation of televisions and display screens. They comprise extra tiny pixels that produce brighter images with better contrast than the other LED display technologies like Organic Light-Emitting Display (OLED), Liquid Crystal Display (LCD), MiniLED, and other traditional display technologies too numerous to mention.

With its configuration, one can easily say that microLED picks up everything about OLED displays and improves it with better features and benefits. Like organic light-emitting diode TVs and other LED walls, micro LEDs have a wider color gamut, fast response time, and better color reproduction, all without sacrificing energy efficiency.

How Do MicroLEDs Emit Light?

As their name suggests, micro LEDs are small in size, measuring around a few micrometers in diameter. Like the traditional LEDs, they operate through a process called electroluminescence. Simply put, electroluminescence is a term that describes the movement of electrons in a semiconductor material to produce light.

When electricity passes through the semiconductor, it charges the electrons and causes them to get excited and move to higher energy levels. After a while, they relax and return to their original positions and release the extra energy as photons. These photons are particles of light that combine to create the picture on your wall display.

The micro LEDs are tightly packed together to produce a high-quality display. Micro LED technology can transmit many colorful and dynamic displays on different screens; it just depends on the material and the design of the LEDs in use. 

Advantages of MicroLED Displays 

Many manufacturers are gradually embracing micro LED technology because of the many benefits it offers to the users. Although it’s not as common as the other LED displays, the microLED has a lot of advantages, which include:

1. High Brightness

Micro LED can reach high levels of brightness without burning out, and this makes them suitable for display in well-lit areas and the outdoors. Unlike the OLED TV, a micro LED can reach a brightness level of up to 5000 nits. Even in areas with direct sunlight, you can still expect top-notch visibility.

2. Longevity and Durability

As bright as the micro LEDs shine, they do not burn out or get damaged easily. Thanks to the LEDs attached to the backplane, there is easier heat distribution and a reduced chance of overheating. With micro-LED displays, you can enjoy up to 100,000 hours of crisp video quality without any glitches or interruptions. 

3. Energy Efficiency

One awesome benefit of the micro LED TV is its self-illuminating feature, which translates to higher energy efficiency. Unlike the OLED and other types of LEDs, this type of display can save up to 50% energy. The portable devices with this microLED technology are not left out, as you’ll enjoy longer-lasting battery life.

4. Scalability

One common limitation most LCDs face is their scalability; they are only usually usable for big screens and TVs, while the smaller devices are left out. Micro LEDs, however, have a wide range of applications, from smartwatches to video walls and even stadium displays. Some screens are adjustable, so you can always set it to your desired viewing angle.

5. Superb Color Gamut

If your main concern is accurate color reproduction, you can trust the micro-LED display to deliver. The LED screen display panel will produce red, green, and blue (RGB) with exceptional accuracy. This feature will greatly benefit professional video and photo editors as it will help them produce high-quality content.

6. Small Pixel Size

The pixel pitch shows the gap between one pixel and another in an LED or microLED display. Generally, a smaller pixel size indicates that the television or screen has a higher resolution and better image display quality and vice versa. This directly affects the pixel density, that is, the number of pixels per inch in a display. 

With a lower pixel density, you will get dull and pixelated images with lower resolution. On the other hand, a higher pixel density will translate to a clearer picture and sharper display. With a reasonable distance and an accurate viewing angle, you can enjoy a clear display from your micro LED display screen. 

7. Increased Eye Comfort

A major concern many LCD users have is the eye strain that comes with constantly using their screens. No one wants to splurge their funds on glasses and treatments at the optometrist. This is why micro LEDs use flat light distribution to help reduce this eye discomfort. The wider light dispersion has been shown to reduce eye strain despite long viewing hours.

8. Elimination of Sub-pixel Arrangements

In OLEDs and other LED screen models, the pixels are arranged side by side, such as sub-pixels, to ensure that the colors are displayed accurately. However, with microLED TVs, the sub-pixel does not exist; hence, the microLEDs themselves serve as the sub-pixels. But this time, they are arranged vertically, with one LED pixel membrane sitting on another and sliced to make a grid-like pattern.

In other display technologies, the blue LEDs are usually placed on top because they have higher energy, unlike the other red and green LEDs. This is not the order with the micro LEDs, as each LED shines brightly and displays a beautiful fusion of the three colors without reducing their brightness.

9. Low Latency

As a gamer, there’s nothing more annoying than a delayed response to your input on the screen. You would most certainly want an instant response as you play to enjoy your game. The micro LED technology is the perfect solution to the high latency issues you may have suffered. Within 40 to 60 milliseconds, your input can reflect on the screen, and your gaming experience will remain seamless.

10. Maintaining Consistent Pixel Density When Scaling

As you enjoy scaling your screens up and down, it’s vital to maintain your display and picture quality; otherwise, the scalability will be in vain. Micro LED manufacturers were intentional to ensure that you can adjust your wall screen without reducing the picture quality. So, with the high pixel density, there will be less motion blur and a premium display of high-quality content.

11. Direct Light Emission

When displaying with the micro LEDs, light is emitted directly as there’s no disruption or blockage. This is because the LEDs are lined up independently and can emit light without lying atop one another. Micro LEDs can have up to 10,000 nits of brightness, while OLEDs usually start at 1000 nits. The microLED wall display has pixels in a configuration that ensures an even light distribution across the microLED screen.  

12. Wide Viewing Angles

If the quality of your display changes when you are not directly in front of your screen, there’s a problem. If people at a distance also have to strain their necks and eyes just to see what is showing on your LED wall, it’s also an obvious limitation.

Although there have been many attempts to develop display technologies that will solve this obvious limitation, the micro-LED display surpasses them all. Whether you’re hosting a game night with your friends or there are hundreds of others watching a screen with you in a stadium, you can be sure of wider viewing angles.

How Do MicroLED Displays Enhance Pixel Density?

Pixel density determines the resolution of your screen and the quality of the image it produces, even on closer view ranges. A higher pixel density means that your picture representation will be vivid and more pronounced, while a lower density means that it’ll be less visible and blurry. But since a microLED display wall takes up everything about known LED screens like OLED and makes it even better, let’s talk about how it also enhances pixel density.

1. More Pixels Same Shape

The pixels in standard LED are significantly big and arranged side by side, and due to their size, it is difficult to fit in more pixels. However, with a micro LED display, more LEDs can fit in the same frame, thanks to its super small size. Consequently, more pixels will lead to higher screen resolution and a better viewing experience. 

2. Higher Resolution

Unlike standard LEDs that mostly have a pixel pitch of 0.9mm, micro LEDs’ pixel pitches can be made lower with an average of 0.5mm pixel pitch. Such configurations can accommodate over 2.5 million pixels/m2. This increase in the number of pixels micro-LED can accommodate is accompanied by better screen resolution for indoor and outdoor displays and various viewing distances.

3. Flexible Content Display Formats

MicroLEDs have more flexibility than standard LED displays; they can be used to manufacture wearable devices, televisions, etc. This flexibility is not limited to the design; it extends to the kind of content you’d like to showcase with your screen. Whether you need a microLED display for home viewing, games, advertising, or entertainment, there’s a plethora of content formats that you can display. 

The micro-LED screen allows users to explore their creative minds and experiment with various content formats that are best for their needs. Additionally, for those in advertising, microLED has smooth remote content management, enabling you to tweak and change content as often as you need.

MicroLED Features

Some of the outstanding features of the microLED display technology include a higher IP rating, and resistance to moisture, dust, and other foreign elements. Any TV screen wall with the micro LED technology is designed with enhanced features that make them suitable for various applications without losing physical or mechanical integrity. Other common features of micro-LEDs include:

1. MicroLED Power Consumption

Even though smart TVs are expected to consume more energy than certain conventional screens, a micro LED television is designed to consume less power than all preexisting displays. Internally and externally, micro LEDs consume over 30% less power than OLEDs. This makes microLED a long-term, cost-effective option because you can save money spent on electricity bills.

2. MicroLED Refresh Rate

For the speed it uses to switch between content in a second, microLED response time is 1000 times faster than OLED, which has a response time of less than 0.1 milliseconds. With microLEDs’ faster refresh rate, gamers, and movie lovers can enjoy watching speedy scenes without worrying about input lag, blurry images, or other LED artifacts.

3. MicroLED Projection Display

MicroLEDs are fueled or inspired by augmented reality (AR), so unlike a standard LED TV wall that also supports projection, micro LEDs have a stack of lenses that collect light from the micro-LED display and project it in a parallel bundle of light. This ensures that more light reaches the eye even under harsh sunlight and bright indoor settings.

4. MicroLED Resolution

Micro LED screen TV offers higher screen resolution options than OLEDs. Though this advancement can greatly affect the price of the screen, it is a one-time investment that ensures that your screen displays images, videos, and other visual content with less pixelation, smooth transitions, and optimum quality by enhancing the difference between whites and blacks.

5. MicroLED Pixel Density

From the size of the LEDs, it’s only logical that the pixel pitch reduces. Picture this: there’s more room for extra pixels that will increase the pixel count and density. So, if a typical LED screen could fit in an average of 0.9mm standard LEDs each in a panel, a micro-LED display will be able to fit in LEDs of 0.5mm or even less! Undoubtedly, any LED screen wall with the micro LED technology has an outstanding pixel density.

MicroLED Manufacturing 

Among the different challenges that come with microLED production, the size will always be a major challenge. Seeing as they are relatively new, there’s a lot of experimenting that goes into the production to get the accurate size for several screens. Not to mention the attempts at deciphering the cheapest way to produce these micro LEDs in commercial quantity.  

The manufacturing process usually starts with wafer fabrication. The wafers come from semiconductor materials like indium gallium nitride (InGaN) or gallium nitride (GaN). After fabrication, different materials are deposited on the wafer to determine its properties like color, size, efficiency, etc. This stage is called epitaxy. 

After that, the wafers are etched to create the pixel layout and then transferred to the actual display panel. The transfer process requires great care and precision and can be done by a pick-and-place method, printing, or microled mass transfer

Upon transfer to the panel, they are transferred again to the substrate and encapsulated to give them a protective layer. At this stage, the micro LEDs will also be tested for the first time. Manufacturers employ several testing and quality control methods to identify and fix any defects.

After a successful microLED inspection, the necessary drivers are installed to integrate the power supply, connections, and signal processing. The final stage is to assemble the display panel into the final product and then seal it for commercial distribution. It could either be a smartwatch, wall TV, gaming monitor, etc.

Even with a laser-focus adherence to these steps, there’s still a likelihood of some technical glitches or malfunctions, especially in novel applications. That is why micro LED manufacturers are expected to engage in constant research and innovation to explore the many possibilities of micro LED display technology. 

MicroLED vs. Other Competing Technologies

The microLED is a fresh approach to digital display; however, the truth remains that there were many other display technologies in place before it came on board. Technologies like LCD and OLED are very capable of giving microLEDs a run for their money. Let’s have a look at some of their similarities and divergencies:

1. OLED vs. MicroLED

The OLED technology relies on organic materials to emit light, while microLED uses semiconductor materials like GaN. Although both technologies can produce vibrant and high-quality picture displays, the OLED is more likely to burn in and produce a fixed image if proper care is not taken.

Since OLED uses organic materials, it is prone to degrade with time, thereby reducing the display’s lifespan. There’s every tendency that your screen will not last as long as you would have wished. 

With a microLED screen, this will be the least of your worries. They are made with sturdy materials that do much more than emitting light. They are sturdy and built to withstand hard weather conditions, direct sunlight, and other elements. .

2. LCD vs. MicroLED

In terms of display technology, the LCD relies on a backlight that passes through liquid crystals to emit light. On the other hand, micro LEDs are self-illuminating and do not need an extra backlight to emit light.

Although LCDs have improved over the years, there are still some obvious limitations in reproducing colors accurately. Their liquid display feature sometimes causes color bleeds and poor contrast. You will not suffer this with microLEDs, as they have better color accuracy and offer higher contrast.

MicroLEDs are more energy-efficient than LCDs, which consume more energy to power their backlight source and stay on. Also, LCDs may have limited viewing angles so as not to reduce the picture quality. However, micro LEDs are more versatile and offer wider viewing angles.

Factors to Consider When Choosing a MicroLED Display

Before you settle on a microLED, you must put several factors into perspective. Truly, human needs are specific, and whatever works for ‘A’ may not apply to ‘B,’ but it is always wise to weigh every possibility and align with your basic needs before settling on a screen.

Here are some things you should consider before you settle on that tiny LED display with microLED technology:

1. Manufacturing Complexities

By nature, micro TV LEDs are designed to be hung up in big and open environments. There are attempts currently ongoing by microLED manufacturers to see that this technology becomes accessible in homes and in smaller spaces. 

The manufacturing process is no small feat, and it requires undivided attention and precision. Any attempt to make anything apart from the usual will require more unplanned steps, and as such, the technology is not readily accessible yet, and the price remains undisclosed.

Suppose you’re not patient enough to wait from the manufacturing process down to the commercialization; you may end up feeling frustrated. Whether it is a big or small LED screen, it needs the touch of a specialist to complete the installation and activation process. However, if you are unfamiliar with this process and its many rigors, you would want to opt for a different display screen.

2. Cost Considerations

As a general rule, the higher the pixels and the resolution, the higher the LED panel TV price. While this may be true, the case isn’t exactly the same for microLED displays because they do not utilize organic materials like OLEDs and are less expensive than the average OLED screen.

However, this is not the only determinant for the price of a microLED screen. Resolution, pixel density, screen size, panel type, shipping, and manufacturing complexities are all factors that can potentially affect the price of a microLED display.

3. Market Adoption and Competition

The microLED technology was not developed with the average screen and home in mind, thanks to its initial configuration. Consequently, this has limited the market adoption rate as only big entities who use big screens will purchase them.

Their success on the big screens has given rise to various experiments and innovations to infuse this technology into regular everyday household and wearable devices. This move is expected to increase the market adoption rate, increase demand, and garner more user anticipation.  

Additionally, they can sell at a competitive rate or even cheaper than OLED screens because of the exemption of organic materials as opposed to its integration in the OLED LED wall screens.

Potential Use Cases in Consumer Electronics

As discussed earlier, micro LEDs are currently not readily available in consumer electronics since they are configured for bigger spaces. However, due to market demand and a promising adoption rate, various manufacturers are working on making it available to the average household.

Soon, microLED displays will be used to manufacture consumer electronics intended for daily use, including microLED smartphones, personal computers, tablet computers, wearables, microLED monitors, televisions, etc. All these devices will be equipped with energy efficiency and high IP ratings to help them maintain their integrity even with consistent use and exposure to various weather conditions.

Impact of MicroLEDs on Emerging Display Technologies

The advancements in microLED displays have set the bar high for emerging display technologies. Manufacturers producing these screens may need to provide features that are better than those of micro LED screens to effectively break into the competitive market. 

Without better features like more energy efficiency, lesser power consumption, brighter displays, deeper contrast, super fast response time, and longer lifespan, they might be the same as OLEDs, SMD LEDs, and other known LEDs.

Conclusion

MicroLED screens are changing the way display technologies are manufactured and used. With better features, more advantages, and potential competitive pricing than OLEDs and other displays, the adoption rate may double that of standard LEDs. 

However, note that household and consumer electronics built with microLED screens are yet to be supplied by most manufacturers. Regardless, other standard LEDs like SMD LED, OLED, and MINI LED are supplied in high quantities and also have competitive features to microLEDs. So, if you need a high-quality and customized LED display for sale that meets your display needs, contact NSE LED.
