摘要-我们展示了一种A4纸大小的柔性铁电液晶（FLC）彩色显示器，该显示器是通过使用一种新的基于塑料基板的工艺制造的，该工艺是为大型设备开发的。精细图案化的滤色器和ITO电极通过转移方法形成在塑料基板上，以避免基板的表面粗糙度和热变形，这引起FLC分子排列的无序。通过使用柔性版印刷和层压技术，在大面积上很好地控制了夹在两个塑料膜基底之间的FLC/单体溶液的厚度。通过使用UV光照射的两步光聚合诱导相分离方法在FLC中形成分子取向的聚合物壁和纤维。制造的用于色段驱动的A4尺寸柔性板显示器即使在弯曲时也能够显示彩色图像。
Abstract— We demonstrated an A4‐paper‐sized flexible ferroelectric liquid‐crystal (FLC) color displays fabricated by using a new plastic‐substrate‐based process which was developed for large‐sized devices. Finely patterned color filters and ITO electrodes were formed on a plastic substrate by a transfer method to avoid surface roughness and thermal distortion of the substrate, which induce disordering of the FLC molecular alignment. The thickness of an FLC/monomer solution sandwiched by two plastic‐film substrates was well controlled over a large area by using flexographic printing and lamination techniques. Molecular‐aligned polymer walls and fibers were formed in the FLC by a two‐step photopolymerization‐induced phase‐separation method using UV‐light irradiation. A fabricated A4‐sized flexible‐sheet display for color‐segment driving was able to exhibit color images even when it was bent.
