Description

一种上下不同配向方式的胆甾相液晶显示屏及其方法
技术领域
本发明是一种上下不同配向方式的胆甾相液晶显示屏及其方法,属于液晶显示屏技术领域。
背景技术
胆甾相液晶是一种具有在空间随意螺旋轴取向的液晶畴,液晶粘度大,如果在胆甾相液晶盒内配向膜上进行常规的摩擦,使得胆甾相液晶具有初始排列方式,会破坏液晶分子螺旋结构的周期性,造成胆甾相液晶显示屏表面光滑如镜的旋光反射,对比度极差的效果。
液晶配向膜作为液晶分子的配向锚定材料,在液晶显示中起着关键的作用。由于液晶分子的运动方式和扭曲不同,所以对液晶配向膜的预倾角的要求也不一样。胆甾相液晶配向膜固含量在原液中占比是很少的小分子化合物,通过高温下产生的聚合反应,形成带有许多支链的大分子固体聚合物的聚酰胺。这种支链与主链的夹角就是配向膜的预倾角。胆甾相液晶分子在液晶盒内沿着配向膜的预倾角有序排列,预倾角决定了液晶分子的初始排列方向。

具体实施方式
本发明是利用上下不同配向方式提高胆甾相液晶显示屏显示效果的方法制作的胆甾相液晶显示屏,胆甾相液晶是在向列相液晶中添加手经济得到的一种具有在空间随意螺旋轴取向的液晶畴,胆甾相液晶分子在同一平面上分子的长轴相互平行,在不同的平面上有不同的取向,各平面的指向矢逐层扭曲,形成周期性螺旋结构。通过在液晶盒内上玻璃下涂覆预倾角为7度的平行液晶配向膜,在下玻璃上涂覆预倾角为80度的垂直液晶配向膜,使得胆甾相液晶在液晶盒内有序排列,形成随着电场变化而变化的有规律的周期性螺旋结构,从而提高液晶显示屏的显示效果。由于胆甾相液晶是一种具有在空间随意螺旋轴取向的液晶畴,液晶粘度大,如果在胆甾相液晶盒内配向膜上进行常规的摩擦,使得胆甾相液晶具有初始排列方式,会破坏液晶分子螺旋结构的周期性,造成胆甾相液晶显示屏表面光滑如镜的旋光反射,对比度极差的效果,但是胆甾相液晶分子具有空间随意螺旋轴取向性,所以必须通过液晶配向膜预倾角让胆甾相液晶分子在液晶盒内有规律的起始排列,便于电场控制胆甾相液晶分子的扭曲,从而达到显示的效果。
