implemented to separate pixels from bleeding into the adjacent pixel. The light dome occupies physical space that can also be used to place a discrete integrated circuit or other micro components such as sensors. Combining mini and micro LED technology can enhance colour and brightness characteristics, leading to better image quality and component reliability, with potential to surpass the standards set by existing OLED technology.
Improved device efficiency Due to the increased number of mini or micro LED die in the same area as that used by a traditional LED, power consumption is more distributed, resulting in more efficient device operation. Mini and micro LEDs can be operated at their maximum efficiency ratings, instead of their maximum drive capability, as with traditional LED applications, resulting in improved thermal characteristics and an overall reduction in power consumption.

Manufacturing benefits Mini and micro LED technology provides several advantages in the process of manufacturing displays: the ability to place the mini or micro LEDs at a desired pitch, select LED components of the preferred size, and the ability to bin components at specified wavelengths.

Black levels are also enhanced with defined zones of the display image now appearing completely black, with the ability to create a genuine representation of ‘true black’. In between each pixel on a direct emission micro LED display is a light dome which is
Binning the small-scale LEDs at a fixed wavelength leads to optimal product performance in terms of luminosity, uniformity, and colour temperature. A variety of LED die size configurations is a key contributor to achieving the desired product design and performance.
A bright future for mini and micro LED
While mini LED can provide performance improvements for existing LCD backlights, micro LED technology promises to be more progressive, offering a display technology that can compete with OLED, with improved brightness, deeply saturated colours and enhanced reliability.
Smaller components and their benefits - enhanced optical performance, reduced power consumption, and the reduced costs of mini and micro LEDs bring new possibilities for many display systems and applications. Understanding the advantages and characteristics of mini and micro LED technology is essential for today’s engineers and designers to create smarter, more efficient display products and systems.
