摘要
降低能耗对于液晶显示器件,尤其是移动显示尤为重要。在本研究中,3nm和5nm两种不同尺寸的CdS纳米粒子被用来掺杂入5CB液晶材料。掺杂浓度分别为0.1wt%和0.2wt%。掺杂所得到的液晶显示器件的开启电压由于纳米粒子的影响而被降低,最多可达到25%。并且,相比于前期报道的金属纳米粒子掺杂的液晶显示器件,CdS纳米粒子显示出稍弱的频率调制特性。
Reduction of power consumption is very important for liquid crystal displays, especially mobile displays. In this study, CdS semiconductor nanoparticles with two diameters of 3 nm and 5 nm were utilized to modify the molecules of 5CB liquid crystal material. The doping concentrations were 0. 1wt% and 0.2wt%, respectively. The CdS-doped 5CB LCD cells show lower threshold voltage than pure 5CB LCD cell because of the influence of CdS nanoparticles on 5CB molecules, the threshold voltage can be reduced by 25% at most. Furthermore,weak frequency modulation response of the electro-optic characteristics was also found in CdS-doped 5CB LCDs,compared with others a previous reported liquid crystal display doped with metal nanoparticles.
