Description
本發明屬於液晶材料領域,具體涉及到一種化合物及其液晶組合物和應用。
使用液晶組合物的液晶顯示元件被廣泛用於鐘錶、計算器、文字處理器等的顯示器中。這些液晶顯示元件是利用液晶化合物的折射率各向異性、介電各向異性等。液晶顯示元件中的運作模式已知的主要分為PC(phase change,相變)、TN(twist nematic,扭曲向列)、STN(super twisted nematic,超扭曲向列)、ECB(electrically controlled birefringence,電控雙折射)、OCB(optically compensated bend,光學補償彎曲)、IPS(in-plane switching,共面轉變)、VA(vertical alignment,垂直配向)等類型。近年來,亦盛行研究對光學各向同性液晶相施加電場而使其表現出電致雙折射的模式。
基於元件的驅動方式的分類主要分為被動矩陣(passive matrix,PM)和主動矩陣(active matrix,AM)。被動矩陣又分類為靜態(static)與多工(multiplex)等,主動矩陣分類為薄膜電晶體(thin filmtransistor,TFT)、金屬-絕緣體-金屬(metal insulator metal,MIM)等。
這些液晶顯示元件包含具有適當物性的液晶組合物。作為液晶組合物的成分的液晶化合物所必須的一般物性如下所述。
(1)化學性穩定以及物理性穩定;(2)具有高透明點(液晶相-各向同性相的相轉移溫度);
(3)液晶相(向列相、膽固醇相、層列相、藍相等光學各向同性液晶相等)的下限溫度低;(4)與其他液晶化合物的相容性優異;(5)具有適當大小的介電各向異性;(6)具有適當大小的折射率各向異性。
包含如(1)所述化學性、物理性穩定的液晶化合物的液晶組合物用於液晶顯示元件,則可提高電壓保持率。另外,若為包含如(2)和(3)所述具有高透明點或液晶相的低下限溫度的液晶化合物的液晶組合物,則可擴大向列相或光學各向同性液晶相的溫度範圍,可在廣泛的溫度範圍內用作顯示元件。液晶化合物為了表現出單一的化合物所難以發揮的特性,通常作為與其他很多液晶化合物混合而製備的液晶組合物來使用。因此,液晶顯示元件所使用的液晶化合物最好如(4)所述與其他液晶化合物等的相容性良好。近年來,尤其要求顯示性能,例如對比度、顯示容量、回應時間特性等更高的液晶顯示元件。進而對所使用的液晶材料要求驅動電壓低的液晶組合物。另外,為了以低電壓來驅動以光學各向同性液晶相所驅動的光元件,最好使用介電各向異性及折射率各向異性大的液晶化合物。
在液晶產品上顯示圖像時,通過施加不同的電壓,可以控制液晶分子旋轉的角度,進而改變光線的穿透量來獲得不同的灰階。如,常白模式的液晶面板,在液晶上沒有施加電壓時,棒狀液晶分子會以近似于平躺的姿態排列,此時光線穿過上下偏振片最多,液晶面板呈現出亮態;在液晶上施加到一定電壓使得液晶垂直站立時,光線幾乎不能通過,此時液晶面板呈現為暗態。而當需要顯示每個中間灰階時,只需在液晶上施加對應電壓即可。
在上述向液晶施加電壓的過程中,如果所施加的電壓固定不變,液晶分子的特性會受到破壞,即使將電壓取消,液晶也無法再隨電場的變化而轉動,從而也無法呈現出不同的灰階。因而,液晶面板的顯示電壓會有正負極性,從而改變施加在液晶上的電壓。如,當液晶面板的顯示電壓高於公共電極電壓時,顯示電壓為正極性;反之,當液晶面板的顯示電壓低於公共電極電壓時,顯示電壓為負極性。不管顯示電壓為正極性還是負極性,當所述顯示電壓與公共電極電壓的壓差絕對值相同時,所呈現出的灰階也是一樣的。
從上述液晶面板的顯示過程可以看出,顯示灰階與光線的透過率是相關的。因而,通過測量液晶面板的透過率曲線,可以進行液晶面板進行電壓設定,從而控制各個灰階的顯示,得出符合人的感官的影像圖形。
傳統的液晶顯示器常常會由於驅動方式以及液晶分子特性的差異,而出現透過率低、閾值電壓大(~2.92V),回應時間慢等問題,進而會造成驅動困難和圖像拖影等現象,因而急需提供一種透過率高且回應迅速的液晶材料。
針對現有技術的缺陷,本發明的目的在於提供一種具
有高的透過率並回應迅速的化合物及其液晶組合物,以及包含所述液晶組合物的液晶顯示元件。
