So, let’s embark on a journey of exploration and discovery!

What is MicroLED?

MicroLED, or Micro Light-Emitting Diode, is an innovative display technology that represents an advancement in the field of visual displays. MicroLED, at its core, comprises microscopic LEDs that serve as individual pixels in a display panel. These tiny LEDs emit light when an electric current passes through them, allowing the creation of vibrant and vivid images.

Unlike traditional display technologies such as OLED (Organic Light-Emitting Diode), and LCD (Liquid Crystal Display), MicroLED uses an array of self-emissive LEDs meaning each of its pixels has its own light. This characteristic eliminates the need for a backlight, leading to enhanced contrast ratio, deeper blacks and fitting colour accuracy.

The active matrix structure is an essential component of MicroLED technology. It consists of a transistor matrix that controls each pixel, enabling precise control over each LED’s colour and brightness. This active matrix framework allows for dynamic and flexible displays capable of rendering high-resolution images and videos.

One of the most prominent microLED displays is their high-quality picture. With unique contrast rations and deep blacks, MicroLED panels offer stunning visuals with lifelike colours and sharp details. In addition, MicroLED displays are also known for their high brightness, which makes them perfect for outdoor environments and well-lit spaces.

Moreover, MicroLED gives a wide colour gamut which means it can reproduce various colours that lead to vibrant and realistic images. This feature is appealing, especially for content creators, designers and those looking for true-to-life colour representation.

Another significant advantage of MicroLED is its energy efficiency. MicroLED panels consume less power than traditional displays, such as LCDs, as they dont need a separate backlight. This energy efficiency helps reduce electricity consumption and contributes to longer battery life that uses MicroLED displays such as smartphones and smartwatches.

In terms of durability, MicroLED displays are well-known for their longevity. They are less susceptible to burn-in, a phenomenon where static images can imprint permanently on the screen. This characteristic ensures that MicroLED displays maintain visual integrity over extended periods, providing a reliable and long-lasting display solution.

How Does MicroLED Work?

MicroLED technology operates with the emission of light from microscopic LEDs. These tiny LEDs serve as individual pixels in a display panel, and when an electric current passes through them, they emit light.

The basic structure of a MicroLED display contains an array of these microscopic LEDs. Each LED is made from three sub-pixels: red, green, and blue, primary colours used to create all other colours in the visible spectrum.

In order to control the emission of each pixel, MicroLED displays employ an active matrix structure. The Thai framework contains a matrix of transistors made from thin-film technology, which maintains the current flowing through each LED.

The active matrix structure ensures precise control over the brightness and colour of each pixel.

By selectively adjusting the amount of current passing through the transistors, the intensity of light emitted by each LED can be controlled, allowing for the creation of different shades and colours.

The self-emissive property of MicroLEDs is a defining feature of this technology. Unlike LCDs, which require a separate backlight to illuminate the pixels, and OLED displays, which rely on organic compounds that emit light when electrically stimulated, MicroLEDs emit light on their own. This eliminates the need for a backlight or colour filter, resulting in improved contrast, deeper blacks, and more accurate colour reproduction.

The individual pixels in a MicroLED display are typically very small, measuring in the range of micrometres. These tiny pixels allow for high pixel density and resolution, making more detailed images sharper.

To create a full-colour image on a MicroLED display, each pixel’s red, green, and blue sub-pixels work in tandem. By combining different intensities of light emitted by these sub-pixels, a wide range of colours can be produced. This colour-mixing process makes accurate and vibrant colour representation at the pixel level.

Overall, MicroLED technology harnesses the power of microscopic LEDs and an active matrix structure to enable precise control over individual pixels’ light emission. This self-emissive characteristic, coupled with high pixel density and resolution, leads to superior picture quality, exceptional colour accuracy, and immersive visual experiences in MicroLED displays.
