Stretchable OLED displays take a big leap forward

Stretchable OLED displays take a big leap forward

A new OLED design can stretch dramatically while staying bright, solving a problem that has long limited flexible displays. The breakthrough comes from pairing a highly efficient light-emitting material with tough, transparent MXene-based electrodes. Tests showed the display kept most of its brightness even after repeated stretching. The technology could power future wearable screens and on-skin health sensors.

Michael’s Miscellany: Observe the Bow-tie Nebula

This celestial wonder sits unassumingly near the head of the northern constellation Cepheus the King within 20° of the North Celestial Pole. Despite its low overall magnitude, the Bow-tie Nebula (also cataloged as NGC 40 and Caldwell 2)makes a fine target through all telescopes because its surface brightness is high. The Bow-Tie sits 5½° south-southeast of the star marking the head of Continue reading "Michael’s Miscellany: Observe the Bow-tie Nebula" The post Michael’s Miscellany: Observe the Bow-tie Nebula appeared first on Astronomy Magazine .
