Mini- and Micro-LEDs are driving innovation in the global display market., offering superior performance, energy efficiency and visual quality compared to other display tech. Micro-LEDs are less than 1/10th the size of a traditional LED, allowing for a much higher pixel density, resulting in a sharper, more vibrant images. Mini-LEDs, while larger than Micro-LEDs, are still significantly smaller than conventional LEDs, and offer a middle ground between LED and Micro-LED tech, allowing for improved performance and efficiency at a lower price point than Micro-LEDs.
Micro-LED and Mini-LED displays consume significantly less power than traditional LED displays, reducing their environmental impact and also improving long-term cost-effectiveness. Lower power consumption results in less heat generation, which can extend the lifespan of the display.
Micro-LED and Mini-LED displays also offer superior visual quality. They can produce deeper blacks and brighter whites, resulting in a higher contrast ratio. They also offer a wider colour gamut. Due to their small size, they are also incorporated into flexible and stretchable displays, facilitating their application in markets including wearables and automotive displays. Apple and Samsung, already incorporate Mini- and Micro-LEDs into their products. Apple utilize Mini-LED technology in the iPad Pro, and Samsung has launched a Micro-LED TV range.
