Description

液晶組合物及液晶顯示元件
本發明屬於液晶材料技術領域,具體涉及液晶組合物及其含有該液晶組合物的液晶顯示元件。
目前,液晶顯示技術已經成熟應用於各類顯示元件中,成為當今訊息顯示領域的主流產品,在儀器儀錶、電腦、電視、手機等各種顯示器中得到了廣泛的應用。根據液晶顯示方式的不同,液晶顯示元件可以分為扭曲向列相(TN)模式、超扭曲向列相(STN)模式、共面(IPS)模式、垂直配向(VA)模式等多種模式。
薄膜電晶體顯示器(TFT-LCD)也迅速成長為主流顯示器,這與它具有的優點是分不開的。
其優點有:1)低黏度,滿足快速反應需求;2)高電壓保持率(VHR),這就需要液晶材料的電阻率高,一般會達到1013Ω.cm;3)較低的閾值電壓,可以滿足低電壓驅動,實現低功耗環保性能; 4)與TFT-LCD相匹配的光學各項異性(Δn),消除彩虹效應,獲得較好的對比度與視角性能。
對於動態畫面顯示應用,消除顯示畫面殘影和拖尾,要求液晶具有很快的反應速度,因此要求液晶具有較低的旋轉黏度γ1;另外,對於便攜式設備,為了降低設備能耗,希望液晶的驅動電壓盡可能低;而對於電視等用途的顯示器來說,對於液晶的驅動電壓低的要求要緩和一些。
液晶化合物的黏度,尤其是旋轉黏度γ1直接影響液晶加電後的反應時間,不管是上升時間(ton)還是下降時間(toff),都與液晶的旋轉黏度γ1成正比關係,上升時間(ton)由於還與液晶盒和驅動電壓有關,可以藉由加大驅動電壓的方法與降低液晶盒盒厚來調節;而下降時間(toff)與驅動電壓無關,主要是與液晶的彈性常數和液晶盒盒厚有關,盒厚的趨薄會降低下降時間(toff),而不同顯示模式下,液晶分子的運動方式不一樣,TN、IPS、VA三種模式分別與平均彈性常數K、扭曲彈性常數、彎曲彈性常數成反比關係。
TFT-LCD面板的透射率是指背光源透過TFT-LCD面板前後的光強之比。TFT-LCD是透射率只有3%~10%的低效率元件,當背光源的亮度為100時,從背光源入射的光藉由面板的各層後,大部分被吸收,最終透過面板後的光亮度只有5,也就是說透射率只有5%,只有一少部分光可以有效的利用、被人眼捕獲。
如果可以對液晶的穿透率進行提高,那麼就可以有效增加TFT-LCD面板的透射率,可以使得更多的光有效被利用;另一方面,也可以降低背光強度,從而實現節省能耗的目的,延長設備的使用時間。
本發明需要解決的技術問題是,提供一種液晶組合物,其光和熱的穩定性好,具有較低的黏度,較快的反應速度,可以得到較為寬泛的折射率、較高的清晰點(很寬的使用溫度範圍),尤其是具有較高光穿透率的液晶組合物、具有較高的亮度或是具有節能省電的效果的液晶顯示元件。
為了解決以上技術問題,本發明提供了一種液晶組合物,包含有一種或多種式I所示化合物、一種或多種式II所示化合物、一種或多種式III所示化合物以及一種或多種式IV所示化合物,

本發明實施例藉由使用式I、式II和式IV所示化合物的搭配組合使用,可以顯著提升液晶組合物的垂直方向的介電各向異性,同時液晶組合物的Δε不會變小,從而能夠大幅提升液晶組合物的穿透率。式III所示化合物具有低的旋轉黏度,還具有較高的清晰點(Cp),與式I、式II和式V所示化合物搭配組合使用,液晶組合物的旋轉黏度降低,反應速度加快。本發明液晶組合物光和熱的穩定性好,具有較低的黏度,較快的反應速度,可以得到較為寬泛的折射率、較高的清晰點(很寬的使用溫度範圍),尤其是液晶組合物具有較高的光的穿透率,因而顯示元件具有較高的亮度或是具有節能省電的效果。
