"unlike OLEDs, micro-LEDs use inorganic materials, which makes them more robust and longer lasting... tiny lights made smaller are dimmer, an especially difficult problem for red light, most important color for making a full-color screen... need for clear/ bright images, compact/ transparent/ flexible/ stretchable displays/ glasses... brightening methods: lasers firing or special liquid guiding micro-LEDs into place, microscopic assembly lines placing/ connecting them faster/ more accurately... VR, AR, smartphones"
