![]() Micro-LEDs, however, are not without their own challenges, and high-volume manufacturing of these displays is among them. Absence of backlight, which allows thinner and lighter displays with lower power consumption.Faster refresh rates, with response times in the nanoseconds.Longer lifetimes, with improved reliability and environmental stability.Higher resolutions due to greater pixel density.Higher luminous efficiency, brightness, and contrast.Of all these options, micro-LEDs - which are miniaturized LEDs in a display matrix - offer the most numerous advantages for display applications 1, including: OLEDs have their own drawbacks compared to LEDs, most notably the burn-in effect, which limits their display life. ![]() While LCD panels are passive displays that need backlight illumination, OLEDs and LEDs are active elements that eliminate the need for backlighting by emitting their own light.
