MicroLED Displays

  • Micro-LED (also known as mLED or µLED) is a display technology that is based on micro LED devices that are used to directly create color pixels.
  • MicroLEDs are self-illuminating diodes that have brighter and better colour reproduction than Organic Light Emitting Diode (OLED) display technology.
  • The first high-resolution and video-capable microLED microdisplay was realized in 2009.
  • The picture in a microLED screen is generated by several individual light-emitting diodes.
  • MicroLED offers greatly reduced energy requirements when compared to conventional LCD displays while also offering pixel-level light control and a high contrast ratio.
  • MicroLED is being touted as the display of the future, including and especially for augmented reality.
  • Pixel density, brightness, contrast efficiency, response time, space requirements and service life of MicroLED is higher than similar technologies.
  • MicroLEDs have limitless scalability, as they are resolution-free, bezel-free, ratio-free, and even size-free an can be freely resized in any form for practical usage.
  • MicroLEDs individually produce red, green, and blue colours without needing the same backlighting or colour filters as conventional displays.
  • Unlike OLED displays, microLED displays use inorganic materials, which also brings in the advantages of ultra-low black levels, but with higher peak brightness.
