摘要

光响应胆甾液晶（CLC）作为可重写纸的有效材料之一，凭借其可调间距和无源显示的特性，为节能和可持续发展做出了贡献。本研究提出了一种具有全色域可调的高分辨率被动显示画布，这归功于引入了二元手性掺杂体系，使CLC的可调光谱覆盖整个可见范围。由于光响应CLC与数字化光场之间的超快相互作用，可以实现光响应材料在任何区域的多维调节，从而获得优异的分辨率性能。此外，通过控制数字化光的曝光量和曝光时间，实现了光谱的精确调制。在我们的系统中实现的理想分辨率约为80 μm，支持重复重写复杂的多色图案，其色域几乎跨越整个可见光谱，范围从420 nm到730 nm。利用clc的光响应特性和数字化光场的精度，不仅验证了高分辨率、全色域被动显示的可行性，而且为研究光场与光敏液晶之间的微观相互作用提供了平台。

Digitalized light driven photo-responsive liquid crystals for high resolution and full gamut passive displaying

Photo-responsive cholesteric liquid crystal (CLC), as one of effective materials for rewritable paper, contributes to energy saving and sustainable development through their tunable pitch and passive display characteristics. In this study, a high-resolution passive display canvas with full-color gamut tunability was presented, which was attributed to the introduction of a binary chiral dopant system enabling the CLC's tunable spectrum to cover the entire visible range. Due to the ultrafast interaction between the photo-responsive CLC and the digitalized light field, multidimensional regulation of the photo-responsive material in any region could be achieved, resulting in excellent resolution performance. Additionally, by controlling the exposure dosage and exposure time of digitalized light, precise modulation of the spectrum was also realized. The ideal resolution achieved in our system is approximately 80 μm, supporting the repeated rewriting of intricate multicolor patterns with a color gamut spans nearly the entire visible spectrum, ranging from 420 nm to 730 nm. By harnessing the photo-responsive properties of CLCs and the precision of digitalized light fields, we not only validated the feasibility of high-resolution and full-gamut passive displaying, but also provided a platform for the study of the microscopic interaction between the light field and photosensitive liquid crystals.
