A liquid crystal active screen for laser speckle reduction
- Abstract:
-
This study demonstrates a novel liquid crystal-based active screen for effective speckle reduction in laser projection displays. By optimising the device architecture, the proposed approach achieves an 88% reduction in laser speckle while maintaining optical throughput. Comparative analysis highlights the advantages of reflective active screens over transmissive designs. Practical demonstrations confirm the device’s ability to suppress speckle across the visible spectrum without degrading image quality.Unlike previously adopted methods these novel devices are simultaneously compatible with high-power projection systems, maintain wide colour gamuts and possess no mechanically-moving components. These findings position liquid crystal active screens as a new promising solution for improving laser projection technology, offering a pathway toward clearer, high-quality projection displays with minimal speckle noise.
