摘要

摘要: 選用單壁及多壁碳納米管摻雜在液晶中制備了扭曲向列相液晶顯示模式液晶盒,采用液晶綜合參數測試儀研究了單壁及多壁碳納米管對扭曲向列相液晶顯示模式液晶盒的驅動電壓、對比度及響應時間的影響.結果表明:單壁及多壁碳納米管的加入均能顯著降低扭曲向列相液晶顯示模式液晶盒的驅動電壓,但對比度也有較大幅度的降低.摻雜單壁碳納米管的液晶盒的開態及關態響應時間均有一定程度的增加,而摻雜多壁碳納米管的液晶盒關態響應時間基本上有所降低,開態響應時間沒有明顯的變化規律.

Abstract: Twisted nematic (TN) liquid crystal display mode cells doped with single-walled carbon nanotubes (SWNT) and multiwalled carbon nanotubes (MWNT) were prepared. The effects of SWNT and MWNT on the driving voltage, contrast ratio and response time of TN liquid crystal display mode cells were investigated with a liquid crystal display parameters tester. It was found that the addition of SWNT and MWNT remarkably decreased the driving voltage and decreased the contrast ratio significantly. The fieldon response time (t_on) and field-off response time (t_off) of TN liquid crystal display mode cells doped with SWNT were higher than those of pure TN liquid crystal display mode cells. For TN liquid crystal display mode cells doped with MWNT, t_off was reduced, but the variation of t_on had no obvious rules.
