OLED and MicroLED (µLED) are both emissive display technologies. The obvious benefit of emissive technologies is the infinite CR and wide color gamut. These technologies also support flexible and transparent designs, bringing more options for the use cases and available form factors. While OLED has established its position as a high-end display technology throughout the applications field, MicroLED is a newer entrant. Due to its excellent luminance capability, long lifetime, high reliability and wide temperature range, MicroLED is expected to break through especially in the automotive market. Yield and cost issues are currently limiting MicroLEDs adoption as a mainstream technology.
Microstructures can be used to manipulate emission angles and increase the light extraction efficiency of emissive displays. Our MLAs have been applied in light management for OLED and MicroLED applications alike.
