Description
本發明涉及液晶顯示領域,具體涉及特定可聚合化合物與特定液晶組分搭配形成的液晶組合物,以及包含有該液晶組合物的顯示元件。
薄膜晶體管液晶顯示器(TFT-LCD)經歷了漫長的基礎研究階段,在實現大生產、商業化之後,以其輕薄、環保、高性能等優點已經成為LCD應用中的主流產品:無論是小尺寸的手機屏、還是大尺寸的筆記本電腦(Notebook PC)或監視器(Monitor),以及大型化的液晶電視(LCD-TV),到處可見TFT-LCD的應用。
早期商用的TFT-LCD產品基本採用了TN顯示模式,其最大問題是視角窄。隨著產品尺寸的增加,特別是在TV領域的應用,具有廣視野角特點的IPS顯示模式、VA顯示模式依次被開發出來並加以應用,尤其是基於VA顯示模式的改進,分別先後在各大公司得到了突破性的發展,這主要取決於VA模式本身所具有的寬視野角、高對比度和無需摩擦配向等優勢,再有就是,VA模式顯示的對比度對液晶的光學各向異性(△n)、液晶盒的厚度(d)和入射光的波長(λ)依賴度較小,必將使得VA這種模式成為極具前景的顯示技術。
但是,VA模式等的主動矩陣尋址方式的顯示元件所用的液晶介質,本身並不完美,例如殘像水平要明顯差於正介電各向異性的顯示元件,響應時間比較慢,驅動電壓比較高等缺點。此時,一些新型的VA顯示技術悄然而
生:像PSVA技術即實現了MVA/PVA類似的廣視野角顯示模式,也簡化了CF製程,從而降低CF成本的同時,提高了開口率,還可以獲得更高的亮度,進而獲得更高的對比度。此外,由於整面的液晶都有預傾角,沒有多米諾延遲現象,在保持同樣的驅動電壓下還可以獲得更快的響應時間,殘像水平也不會受到影響,但是由於像素中Fine Slit密集分佈電極,故如果電極寬度不能均勻分佈,很容易出現顯示不均的問題。像UVVA技術,在保持PSVA技術優勢的基礎上,由於在TFT側沒有Slit結構,出現像素電極寬度不均引起的顯示不均問題還得到了改進。雖然顯示器件在不斷的發展,但是人們還要一直致力於研究新的液晶化合物,得以使液晶介質及其應用於顯示器件的性能不斷的向前發展。
可聚合介晶單元(RMs)目前是顯示行業非常熱門且重要的課題,其可能應用的領域包括聚合物穩定配向(PSA)液晶顯示,聚合物穩定藍相(PS-BP)液晶顯示以及圖形化位相差膜(Pattern Retarder Film)等。
PSA原理正被應用在不同典型的LC顯示器中,例如PSA-VA、PSA-OCB、PS-IPS/FFS和PS-TN等液晶顯示器。以目前最為廣泛應用的PSA-VA顯示器為例,通過PSA方法可以獲得液晶盒的預傾角,該預傾角對響應時間具有積極的影響。對於PSA-VA顯示器,可以使用標準的MVA或PVA像素和電極設計,但是如果在一側的電極設計採用特殊圖形化的而在另一端不採用突起的設計,可以顯著的簡化生產,同時使顯示器得到非常好的對比度、及很高的光透過率。
現有技術已經發現LC混合物和RMs在PSA顯示器中的應用方面仍具有一些缺點。首先,到目前為止並不是每個希望的可溶RM都適合用於PSA顯示器;同時,如果希望借助於UV光而不添加光引發劑進行聚合(這可能對某些
應用而言是有利的),則選擇變得更小;另外,LC混合物(下面也稱為“LC主體混合物”)與所選擇的可聚合組分組合形成的“材料體系”應具有最低的旋轉黏度和最好的光電性能,用於加大“電壓保持率”(VHR)以達到效果。在PSA-VA方面,採用(UV)光輻照後的高VHR是非常重要的,否則會導致最終顯示器出現殘像等問題。到目前為止,並不是所有的LC混合物與可聚合組分組成的組合都適合於PSA顯示器。這主要是由於可聚合單元對於UV敏感性波長過短,或光照後沒有傾角出現或出現不足的傾角,或可聚合組分在光照後的均一性較差,或因為UV後VHR對於TFT顯示器應用而言是較低等方面的影響。
本發明提供一種可聚合化合物以及這種可聚合化合物與特定液晶組分搭配形成的液晶組合物以及包含該液晶組合物的液晶顯示元件,尤其適用於顯示器或TV應用的PSVA液晶組合物,以及IPS模式的PSA-IPS液晶組合物,尤其是可聚合化合物具有較快的聚合速度並且所選擇的可聚合組分與液晶組分形成的“材料體系”具有較低的旋轉黏度、較好的光電性能,且採用(UV)光輻照後具有高的VHR,避免了最終顯示器出現殘像等問題。

1.聚合性化合物的轉化率
測定可聚合化合物製備得到的液晶介質在用於液晶顯示器件中的聚合速率:以對比例6中去掉RM-1的混合物為母體MUTY,分別向其中添加2500ppm的實施例1~6的可聚合化合物RM;作為對比,分別向MUTY中添加等量對比例1-5的RM,以上述提到的液晶介質製備方法製備成液晶介質,灌注液晶盒後,模擬PSA面板製程,測定其聚合速率,具體條件:UV1:80mW/cm2@ 365nm,200s;UV2:5mW/cm2@ 365nm,120min,再剖開液晶盒進行HPLC分析,結果如下表4所示。
從轉化率可以看出,的存在,加快了反應速度,提高了相同時間內的轉化率,本發明提供的可聚合化合物優於對比例的現有技術。
而且,與對比例4在具有同樣快速的反應時間下,同時具備均勻細密的顆粒物形態,優化了形成的預傾角。可以看到對比例3和對比例4形成的角度偏大,也就是較小的預傾角,這會造成響應時間變慢。在引入了後,改善了預傾角,因此可以縮短響應時間。
而對比例5,由於反應時間過快,導致形成的顆粒物偏大,不均勻,形成的預傾角太大,造成了漏光現象。本發明提供的可聚合化合物在保持了較快的反應時間的情況下,形成的顆粒均一,預傾角適當,技術優勢明顯。
2.響應時間
將各種可聚合性化合物和液晶化合物而製備的混合物注入至器件中。通過照射紫外線來使聚合物性化合物聚合後,測定器件的響應時間。未添加聚合性化合物與液晶化合物的混合物時,響應時間慢。因此,可得出結論:有本發明涉及的聚合性化合物和液晶化合物的組合在縮短響應時間方面有效。
3.信賴性
將各種可聚合性化合物和液晶化合物而製備的混合物注入至測試盒中。通過照射紫外線來使聚合物性化合物聚合後,再在紫外線、高溫等條件下測試其電壓保持率(VHR),較佳高信賴性液晶,即高VHR(16.7ms)。
