Flexible speckle-free polymer-stabilized liquid crystal screen for laser projection
Despite considerable effort and progress, accomplishing speckle-free laser displays remain challenging, particularly in flexible displays. In this paper, we propose a novel and easy-to-implement method for developing a flexible polymer-stabilized liquid crystal (PSLC) screen. A uniformly alignment layer was achieved on polyethylene terephthalate substrates using a low-temperature curing system, and polystyrene (PS) microspheres are spin-coated to enhance the mechanical stability. The dynamic scattering of the PSLC effectively reduces laser speckle, leading to improved image clarity. When applied to a laser projection system, the developed flexible PSLC screen exhibits good image quality, low light-intensity loss, and a speckle suppression efficiency of 77.9%. Furthermore, it exhibits excellent optical performance, mechanical stability, and size adaptability, which are suitable for applications in flexible, transparent, and augmented/virtual reality displays; and other optical imaging scenarios.
期刊介绍:
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
