With advances in technology, requirements for the performance of liquid crystal displays (LCDs) are gradually increasing, especially for flexible displays, which involve many new challenges. Here, we propose a new method for implementing optically driven LCD flexible displays. Upon doping an E7 nematic liquid crystal (LC) with RM257 liquid crystal monomer and polymerizing it using ultraviolet light, a polymer network forms as the spacer between the two substrates of the LC, maintaining the surrounding E7 LC in a relatively stable state and improving the mechanical properties of the LC. This also endows the LC mixture with a limited capacity for deformation recovery and enables uniform deformation under stress, thereby achieving flexible displays. Applying an electric field to the two ends of the LC cell, the viscosity coefficient of the LC molecules is improved and the rewriting time can be optimized. This type of LC cell can be programmed through light control, achieving low power consumption for a wearable display device.

基于RM257掺杂的柔性光驱动液晶显示器

随着技术的进步，对液晶显示器（LCD）的性能要求逐渐提高，尤其是柔性显示器，这带来了许多新的挑战。在这里，我们提出了一种实现光学驱动 LCD 柔性显示器的新方法。在 E7 向列液晶 (LC) 中掺杂 RM257 液晶单体并利用紫外光进行聚合后，在 LC 的两个基板之间形成聚合物网络作为间隔物，使周围的 E7 LC 保持在相对稳定的状态，并提高了LC 的机械性能。这也赋予液晶混合物有限的变形恢复能力，并能够在应力下实现均匀变形，从而实现柔性显示器。在液晶盒的两端施加电场，可以提高液晶分子的粘度系数，并优化重写时间。这种类型的液晶单元可以通过光控制进行编程，从而实现可穿戴显示设备的低功耗。
