By integrating super-aligned carbon nanotube (SACNT) movies with paraffin wax, an addressable optical valve composite array was created by display screen printing and laser slicing. The temperature of the SACNT movie could be managed, which quickly induces section adjustments within the paraffin wax, resulting in a swift change in optical transparency. The transmission spot exhibited important variations, with a distinction diploma reaching as much as 0.65. At a paraffin wax floor density of 1.17×10-4 g/mm2, the rise and fall occasions of the transmitted optical sign throughout the 350–1100 nm spectrum have been 155 ± 2 ms and 135 ± 11 ms, respectively, enabling fast spatial gentle modulation. A prototype was fabricated, able to dynamically displaying letters, with the crosstalk impact of the present being considerably mitigated in spatial gentle modulation. This fast spatial modulation prototype could be personalized to any form and dimension, and it may well both be freestanding or mounted on any substrate. This innovation presents a brand new strategy to spatial gentle modulation.
