| Résumé: | © 2024 The Author(s). Advanced Materials published by Wiley‐VCH GmbH. Conventional laser panel displays are developed through the mass integration of electrically pumped lasers or through the incorporation of a beam steering system with an array of optically pumped lasers. Here a novel configuration of a laser panel display consisting of a non-steered pumping beam and an array of electrically Q-switchable lasers is reported. The laser oscillator consists of a robust, self-standing, and deformable minute droplet that emits laser through Whispering-Gallery Mode resonance when optically pumped. The laser oscillation is electrically switchable during optical pumping by applying a vertical electric field to the droplet. Electromagnetic and fluid dynamics simulations reveal the deformation of the droplet into a prolate spheroid under the electric field and associated attenuation of quality factor (Q-factor), leading to the halt of the laser oscillation. A 2 × 3 array of droplets is fabricated by inkjet printing as a prototype of a laser panel display, and it successfully achieves the pixel-selective switching of the oscillation |
