by | Nov 7, 2023 | Blogs | 0 comments

What is Micro LED?

Micro LED, also known as a micro light-emitting diode, is one of the most recent advancements in display business and technology. It has certainly made headlines over the past few years and offered a shift towards cutting-edge displays. Such screens are made of numerous diodes that are self limited and act as individual pixels for an improved viewing experience. “micro” would make you think about the small dimension of the pixels displayed by such LEDs. The core concept behind micro LED is to use these minuscule LEDs for generating displays instead of traditional LED and LCD approaches. Micro LED screens are self-emitting, unlike typical LCDs, which use a backlight to illuminate the entire screen. Each LED is responsible for emitting light. This feature offers more power over the contrast and brightness of the display, which results in enhanced and precise graphics.

You might be aware of a few applications using Micro LEDs, but what might be interesting to know is that the display uses inorganic materials. The most important one is GaN (gallium nitride), which is the foundation for the small LEDs. These substances have various advantages, including excellent performance, durability, and ability to withstand burn-in, which can be an issue with other displays such as OLED. Because of their tiny size, these LEDs can create screens with highly high pixel densities, resulting in amazingly crisp and intricate images. Micro LED screens connect these tiny LEDs to a substrate, often a printed circuit board. These LEDs are precisely placed and arranged, each corresponding to a distinct pixel on the screen. Because tiny LED displays are self-emitting, they may attain flawless blacks and endless contrast metrics, contributing to improved image quality. This technology is highly versatile and may be scaled to various sizes and purposes.

It is most commonly found in tiny gadgets like cellphones, watches, and Augmented Reality, where high pixel density is essential for clear visuals. LED micro display might be scaled up to create larger screens, making them suitable for broadcasts, digital indicators, and theatre screens. The compact size also enables for more excellent energy-efficient performance. Each LED may be changed independently of one another, allowing for precise control of electrical consumption. Once a pixel is switched off, it requires no power, resulting in cost-effective micro-LED displays. This technology not only reduces energy usage but also increases the lifespan of the batteries of portable devices equipped with micro-LED displays.

In short, micro LED is a new display technology that uses small, self-emissive LEDs to create excellent-quality screens. Its high pixel density, self-emissive features, scalability, and energy economy make it an appealing option for various applications. Micro LED has been shown to revolutionise how we engage with visual material, either in small portable gadgets or large-scale screens.

Given that each pixel emits its light, micro LED technology provides exceptional picture quality with bright colours, outstanding contrast ratios, and precise blacks. Let’s discuss a few other benefits of such displays:

  • Its capacity to produce exceptionally bright levels qualifies it for high-dynamic-range (HDR) content, resulting in excellent peak brightness and better contrast in well-lit areas.
  • Micro LEDs outperform specific competitors when it comes to resilience and endurance since they are very resistant to burning in as well as possessing a longer lifespan, especially when weighed against OLED displays.
  • They can also be cost-effective by only flashing the needed pixels, minimising electrical usage during gloomy scenarios.

Nonetheless, there are some significant negatives to consider.

  • The cost of manufacturing and acquiring Micro LED screens is relatively low, limiting their availability.
  • The sophisticated production process, which necessitates a billion tiny LEDs, can cause manufacturing problems and potential faults, adding to the final cost. While compact Micro LED panels are more viable, bigger ones are more difficult and expensive.
  • The extreme brightness levels attained by Micro LEDs may produce heat, demanding proficient heat management methods to minimise overheating and preserve the longevity of the display.

Micro LED technology provides excellent display quality and endurance at a high cost and with significant manufacturing complexity. It can become a crucial player in the visualisation business as technology progresses.

Micro LED screen Vs  OLED Display

Micro LED screen and OLED (also termed Organic Light-Emitting Diode) are two essential contenders in display gadgets, each having its own set of benefits and limitations. It’s already established that they provide stunning viewing experiences and can change how we view and communicate with screens. Let’s look at the fundamental features of Micro LED and OLED screens, as well as their advantages and disadvantages.

  • The technology of display:

Micro LED screens has micro-sized LEDs, each of which can emit light. They’re also self-emitting, so exact control over the brightness and colour of each pixel is possible. OLED displays, on the other hand, use organic chemicals that generate light when the electricity flows through them. While OLEDs are likewise self-emitting, their organic nature makes them prone to damage over time.

  • Image Quality:

There are a bunch of benefits of OLED and micro-LEDs as far as image quality is concerned. As you might already know, micro LEDs offer amazing image quality with the best ratios of contrast and black. Individual pixel control guarantees that each pixel produces the right light, creating crisper and more realistic images. OLED displays are also good, with deep blacks and vivid colour. However, OLEDs are susceptible to burn-in, which occurs when a static image is displayed for an extended period and causes permanent damage.

  • Brightness:

In terms of brightness, micro LED panels offer a significant advantage. They have extraordinarily high brightness scales, making them excellent for HDR stuff. This functionality is especially appealing in well-lit areas where the display must contend with ambient light. Although OLED displays may achieve high brightness levels, Micro LED screens outperform them in this regard, particularly at bigger panel sizes.

  • Lifespan and Durability:

Micro LED display panels are exceptionally resilient and have an extended lifespan when weighed against OLED displays. Because of their inorganic structure, they are resilient to burn-in, and this can be an issue with OLED screens, particularly in applications where still pictures are presented for extended periods. Micro LED displays have a longer lifespan, making them a more cost-effective solution.

  • Size Restrictions:

Although Micro LED technology emerges in smaller screens,  the production process gets more difficult and expensive. OLED screens, on the other end of the spectrum, are more adaptable and can be adjusted to various dimensions with ease.

  • Heat Management:

Because of the high brightness levels, Micro LED panels and OLED screens require good heat management. Micro LEDs may necessitate specialised cooling techniques to prevent overheating, particularly in large, brilliant displays. OLEDs also produce heat, but organic substances may be more temperature-sensitive, making controlling heat a critical factor.

Is MicroLED better than OLED?

When analysing MicroLED and OLED screen technologies, size constraints are an essential factor to consider. While microLED provides excellent picture quality and longevity, it has restrictions, especially when it relates to producing larger screens as the dimension of the microLED screen increases. The production process gets more difficult and expensive. This limits the usage of MicroLED in uses that demand large screens, such as large televisions or digital billboards.

OLED’s size adaptation not only meets a variety of purposes, but it is also more cost-effective, making it the favoured choice in many situations where screen size diversity is critical. OLED displays, on the other hand, have greater versatility when it comes to size, consequently making them a popular choice for a variety of applications. They can be adjusted to various sizes without running into the same production issues as MicroLEDs. Because of their adaptability, OLEDs can be employed in various applications, from small mobile devices to enormous wall-mounted displays.

The choice between the MicroLED and OLED is influenced by several factors, one of which is size. While MicroLED sparkles in compact displays and provides exceptional image quality, it may not be the most significant choice for applications that require larger screens. In such circumstances, the versatility of OLED makes it the ideal technology. Finally, the decision should consider unique needs, budget limits, and the significance of screen dimension and image quality.
