More brilliance thanks to inner radiance
Liquid crystal displays - LCDs - still dominate the market today. LED, i.e. light-emitting diodes, are only used as white versions for backlighting. It is true that colour LEDs can also be produced for a long time, which can be grouped in groups of three (in the RGB colours red, green and blue) into one pixel of a colour display. Due to the size of these LED groups, however, the system is only suitable for large screens, e.g. as advertising boards or displays in stadiums.
The industry has long been keen on LED technology, which can be reduced to such an extent that it can also be used in consumer electronics - especially in mobile devices - not only for lighting but also for the independent display of content in natural colours. And another criterion is immensely important: the lowest possible energy consumption. After all, even the most exciting technological innovation is not much fun for the user if the battery needs to be recharged after just a few hours.
OLED (Organic Light Emitting Diodes) have been available for some time now - LED made of organic semiconducting materials that light up themselves, i.e. do not require backlighting. OLED have excellent black values and represent a wide colour spectrum. However, they are currently still quite expensive to manufacture, not very bright, suffer from burn-in effects under certain conditions and do not yet reach the service life of conventional displays.
The hottest contender for the top position on the market is therefore a new competitor - the Micro LED: Compared to the current display technology, it offers a higher pixel density, a longer lifetime, greater brightness, a higher switching speed and a wider colour spectrum - all advantages that make it groundbreaking for a large number of current and future application scenarios. In addition, the Micro LED is particularly characterized by its very low energy consumption - a fact that predestines it especially for future generations of small mobile devices with little space for batteries.
No wonder that virtually all major display manufacturers are now preparing for the future and are looking for production processes that are as reliable as they are economical.
