Abstract
- Flexible laser display is a critical component for an information output port in next-generation wearable devices. So far, the lack of appropriate display panels capable of providing sustained operation under rigorous mechanical conditions impedes the development of flexible laser displays with high reliability. Owing to the multiple scattering feedback mechanism, random lasers render high mechanical flexibility to withstand deformation, thus making them promising candidates for flexible display planes. However, the inability to obtain pixelated random laser arrays with highly ordered emissive geometries hinders the application of flexible laser displays in the wearable device. Here, for the first time, we demonstrate a mass fabrication strategy of full-color random laser arrays for flexible display panels. The feedback closed loops can be easily fulfilled in the pixels by multiple scatterings to generate durative random lasing. Due to the sustained operation of random laser, the display performance was well-maintained under mechanical deformations, and as a result, a flexible laser display panel was achieved. Our finding will provide a guidance for the development of flexible laser displays and laser illumination devices.
