Definitions
- the present invention relates to the field of display technologies, and in particular, to a PDLC display panel, a method for fabricating the same, and a liquid crystal display device.
- Polymer Dispersed Liquid Crystal is a method in which a low molecular liquid crystal (LC) is mixed with a prepolymer and polymerized under certain conditions to form micron-sized liquid crystal droplets uniformly dispersed at a high level.
- the dielectric anisotropy of the liquid crystal molecules is used to obtain a material having electro-optic response characteristics, which can realize a dark state in a light state and a power-off state in an energized state, and mainly works in a scattering state and a transparent state. There is a certain gray level between them.

Description
本发明涉及显示技术领域,尤其涉及一种PDLC显示面板及其制作方法与液晶显示装置。
聚合物分散液晶(PDLC,Polymer Dispersed Liquid Crystal)是将低分子液晶(LC,liquid crystal)与预聚物相混合,在一定条件下经聚合反应,形成微米级的液晶微滴均匀地分散在高分子网络中,再利用液晶分子的介电各向异性获得具有电光响应特性的材料,可以实现在通电状态下的亮态与断电状态下的暗态,它主要工作在散射态和透明态之间并具有一定的灰度。
聚合物分散液晶膜是将液晶和聚合物结合得到的一种综合性能优异的膜材料。液晶分子赋予了聚合物分散液晶膜显著的电光特性,使其受到了广泛的关注,并有着广阔的应用前景。相对于传统显示器件来说,聚合物分散液晶显示器具有很多优点,例如不需要偏振光片和取向层,制作工艺简单,易于制成大面积柔性显示器等,目前已在光学调制器、热敏及压敏器件、电控玻璃、光阀、投影显示、电子书等方面获得广泛应用。
现有市场上的液晶显示装置(LCD,Liquid Crystal Display)大部分为背光型液晶显示装置,其包括液晶显示面板及背光模组(backlight module)。通常液晶显示面板由彩膜基板(CF Substrate,Color Filter Substrate)、薄膜晶体管基板(TFT Substrate,Thin Film Transistor Substrate)、夹于彩膜基板与薄膜晶体管基板之间的液晶、密封胶框(Sealant)、以及偏振光片组成;但是该结构的液晶显示面板对光的吸收、过滤作用强,如上下两偏振光片通常能过滤、吸收掉超过55%的光强,彩色滤光片可吸收掉超过2/3的光强,因而现有液晶显示装置的背光利用率极低,约5~8%左右。
当前出现的新材料量子点以其优异的发光特性,诸如窄发光峰,可调谐的发光波段,高的内量子效率为显示行业带来了新的色彩发展空间。
因此,将PDLC与量子点结合成新型显示器势必成为显示行业以后研究的重点。
